TrackMe's web development and user plugins. Developers welcome!!

As some people suggested I'm creating an specific thread for TrackMe's web development.
TrackMe is a free GPS/WiFi/Cell ID tracking tool. You can watch your tracks (saved or live) with Google Earth, Google Maps (or any tool that accepts KML or GPX files). It also includes many other options and features.
You can also watch your tracks from the web. This thread is focused on that part.
TrackMe is available for Android, Windows Mobile and Windows Phone 7. Check my signature for support for each version.

1. TrackMe (NMEA records) to OziExplorer (.plt) converter by tahdor
Description:
Simple perl script which takes the TrackMe (NMEA records) and put them as OziExplorer (.plt) format. Then you can open the .plf record in GpsVp to view the track.

2. User limitation for web viewer access by Real_Justus
Description:
Limit access to Web viewer for servers running in public mode
I was wondering how I could limit the access to my server. I wanted a group of users to be able to track all TrackMe clients via GoogleMaps.
The attached three files will enable a simple authorization for users. The server has to be installed accessable for everyone (public).
To create the authorziation, you have to edit .htaccess and htpasswd from the ZIP attached as follows:
1: Open .htaccess with the texteditor.
2: In the line "AuthUserFile" you have to add the WHOLE path to .htpasswd.
3: .htpasswd contains the users. The username is just plain text. The password is ht-encrypted. You can encrypt passwords here.
4: When both files are modifyed for your needs, upload them to the TrackMe directory on your server. If this is done correctly, a simple authorization is required for opening the webinterface for your TrackMe-server. All valid users can Track all clients.
If you don´t know the exactly path, upload phpinfo.php from the ZIP attached to the TrackMe directory on your server and open the file in your browser. (http://www.yourserver.com/TrackMe/phpinfo.php). Search for "Document_ Root" The path might be something like: /var/www/user/html/YourTrackMe/Directory. Insert the path in .htaccess
!!!Make sure to delete the phpinfo.php after use!!!

3. Plugin that allows you to assign multiple pictures to a single position by ElHozo
Description:
I've made a change in tod files of the server to allow view of multiple pictures in on dialog ballon. This (at least for me) is very usefull when you want to take many pictures from one place (no position change)
You have to edit to files
in request.php make this change to allow having multiples images in one single position record
Code:
if($action=="updateimageurl")
{
$imageurl = urldecode($_GET["imageurl"]);
$id = urldecode($_GET["id"]);
$iconid='null';
$result=mysql_query("Select ID FROM icons WHERE name = 'Camera'");
if ( $row=mysql_fetch_array($result) )
$iconid=$row['ID'];
/* HOZO 20/Jun/2009 : Esta es la modficacion que permite poner mas de una
* imagen en un solo punto, pone las url una atras de otra saparadas por un
* espacio. la linea que queda comentada es la original.
* Ver en index.php el cambio que las muestra en el globo del dialogo */
// BEGIN ORIGINAL CODE - MUST BE COMMENTED
//mysql_query("update positions set imageurl='$imageurl',fk_icons_id=$iconid where id=$id");
// END ORIGINAL CODE
// BEGIN NEW CODE
mysql_query("update positions set imageurl=CONCAT_WS(' ', imageurl, TRIM('".$imageurl."')), fk_icons_id='".$iconid."' where id='".$id."'");
// END NEW CODE
echo "Result:0";
die();
}
in index.php change this to show multiple images in one dialog balloon
Code:
if($row['ImageURL'])
{
/* HOZO 20/Jul/2009 : Agregar este pedazo de codigo en reemplazo del orginal,
* la ultima linea que esta comentada es la orgiinal.*/
// BEGIN NEW CODE
// Por las dudas me aseguro de eliminar espacios duplicados
$row['ImageURL'] = eregi_replace (" ", " ", $row['ImageURL']);
$row['ImageURL'] = eregi_replace (" ", " ", $row['ImageURL']);
$stFotos = explode (" ", trim($row['ImageURL']));
// Armo la cantidad de columnas y tamaño de la imagen del globo
// de acuerdo a la cantidad de fotos que haya para mostrar
if (count ($stFotos) == 1)
{
$inFotosCols = 1;
$inImgWidth = 200;
}
else
{
$inFotosCols = count ($stFotos);
if ($inFotosCols > 16)
$inFotosCols = 5;
else if ($inFotosCols > 9)
$inFotosCols = 4;
else if ($inFotosCols > 3)
$inFotosCols = 3;
$inImgWidth = ( 400 / $inFotosCols ) - 5;
}
$html .= "<tr><td>";
$html .= "<table>";
$inFotoIndex = 0;
while (list ($inKey, $szData) = each ($stFotos))
{
if ( ($inFotoIndex % $inFotosCols) == 0)
$html .= "<tr>";
$inFotoIndex++;
$html .= "<td><a><img></a></td>";
if ( ($inFotoIndex % $inF";
}
$html .= "</tr>";
$html .= "</table>";
$html .= "</td>";
$html .= "</tr>";
// END NEW CODE
// La que sigue es la linea orignal de codigo
// BEGIN ORIGINAL CODE - MUST BE COMMENTED
//$html .= " <tr><td><a><img></a></td></tr>";
// END ORIGINAL CODE
}
Know issues : The filed imgeurl in DB is limited to 255 chars, is better if you change this value to something bigger to fit more images urls.
I have included a ZIP with the two modified files

Great new thread!
Let the development begin!

With the advice of timoline I'm playing (and I'm trying to understand) with open-flash-chart.
Here is my first try :
When you move the mouse on the graphic, there is a sticker with the speed.
I'm trying to add the altitude on red with the Y axis right. But It doesn't works for now.
Thanks for your advice Timoline .

Is there some sort of ocumentation about the TrackMe <-> Webserver communication? It would be nice if you can write a little about this.
I point as I browsed the source I saw that the password was transmit unencrypted maybe you can change that to md5 or somthing similar?
Btw. Trackme is a great App

Thanks.
Unfortunately there is not doc about the server-client communication.
However, feel free to ask any questions about that here.
Regarding the encrypted pass... yes, that's in the to-do list (actually it has been there for a long time) but there is something that I want to ask.
Let's suppose that from the client I do $encrypted = encode_md5(password)
And now that's what I send to the server.
On the server side, should I do $pass = decode_md5 ($encrypted) ?
or it's not necessary because I am going to store the pass already encrypted in the database?
And one more thing, what's really the purpose of that encoding? If somebody has access to the encrypted password, wouldn't he be able to do the same things than if it is not encrypted?
I mean if I my password is role392 and the encryped one is sadj2jkfDk43j54... what's really the difference? Both are like regular passwords.
I hope it makes sense.

It makes more or less sense
Normal a webapp stores the password 'encrypted' with md5 in its Database. From the Login it gets clearly send per Post and the server will 'encrypt' it. Then it verfy it against the md5 hash in the db. You will be still able to sniff it but if the DB gets hacked you will only have the md5 values which can't be decoded. Also because of the Post-Method the Pass is not clearly visible in the URL.
Thats not much secruity but a little more. Maybe you can XOR the md5 with the actuall hour/minute at the client side and send it. At server-side you will do the same with the saved md5 an look if they are the same. This is a little more secure but not much.
I hope you understand me and my 'broken' Englisch
For the Docs I will have a look at the code when there is Time because I'am on a tenancy changeover(?).

Language Update
I've updated the dutch part in the language.php from jcleek's web viewer.
See attachment:

I've been working on my own server development, at the moment I have:
1. Weather at the persons current or last postion.
2. Address of the persons current or last position (I think US only)
3. Geofence option that texts whoever the user wants to text when the user has entered a predefined area.
4. Ability to place markers on the map for whatever purpose the user chooses, business, personal or otherwise.
5. The server stores the mileage driven in each state or country if the user chooses for fuel tax or other reasons.
6. Server is not just limited to Trackme, it can also be an alturl for Mologogo, and a custom server for GPSGate. Server still retains all Trackme functionality.
http://fleettracking.fleettrack.net/maps.php
The frontend is still a little "raw", as I am concentrating on the back end for the moment.

Thanks a lot for the detailed explanation!!
I think I will start by encoding it in MD5 only in the database. I may add the XOR later.

hey looks good!! Let me know when you have something to release so I can add your viewer in the first post.
Thanks a lot for your contribution.
and please keep us updated!

Not so detailed but some basics maybe you will have a look at http://en.wikipedia.org/wiki/Md5 or http://en.wikipedia.org/wiki/Sha-1
Another thing, is it possible to have the server running on an selfsigned ssl server ?
The next point is. I've made a list of functions/ requests required by TrackMe on the Serverside.
Can you have a look at it staryon? The other aswell
I hope I made no mistake and all is there also its not very well layouted but better than nothing. Some function doesn't have an errorcode is this right? or not implentet a serverside?

Unless I missed something it looks ok to me.
I just updated the second post inside this thread with information about the server-client communication.
Please let me know if you need information about a specific parameter.

The only things which are from interest as well are the Date / Long / Lat / .... dataformats, but they are all in the DB like they transmited, if I am right?
Maybe one last thing have you some testing app or something else to test the communication without Trackme and the Phone because my Dataplan is not unlimited. Else I will make manual Request iin the webbrowser.
thanks for your quick responses
EDIT:
Ok found out some Formats
Date - YYYY-MM-DD HH:MM:SS
lon/lat - xx.XXXXXX -
WGS48 ? - but then the dot is moved 2 left and there are no East,West,Nord,South data? Can you help me here with the format?
BatteryStatus in % 0-100
Singalstrengh in dB ? -xxx
CID - X-X-XXX-XXXXX
For these I've no Data because there are no Trips with GPS in the DB, waiting for my X1.

Here is how the GET is given to the server (this is an actual one pulled from my logs). I use CDMA, so I can't use CELLID:
requests.php?a=upload&u=xxxxxxxx&p=xxxxxxx&lat=37.54446&long=-76.8039466666667&do=2009-2-2%209:18:19&tn=02-01-09&alt=-31.4&sp=&ang=77.2&bs=100&db=8
I round the lat and lon to 5 places after the decimal as anything more is just wasted db usage.

You're right, I would like to truncate those values before being sent to the server one day...

Why the basic OPENGL ES app can not run on my Touch HD?

Hi, all.
I find this perfect site through Google after I bought a Blackstone.
I want to do something on my phone, that's OpenGL ES.
When I download the sample code "7 OpenGL ES Tutorials for Win32/WinCE from TyphoonLabs" from khronos and compile them. The samples run well on the Windows Mobile 6.5 Emulator. (there is no libGLES_cm.dll file in the windows folder)
But, when I copy the exe files to my Blackstone, they failed to run. The Tutorials 1 only flash a title then over.
I can find a libGLES_cm.dll file in the windows folder of my Blackstone. It is 322KB, smaller than others I can get. (such as 491KB 10-10-2004). I can't replace it or delete it.
I think the 1st sample of TyphoonLabs is a typical and basic OpenGL ES app, it has not use any advanced ES feature.
however, VR HOLOGRAM runs well on my phone.
I installed "Ati d3d driver", and my app development environment is:
Visual Studio 2008
Windows Mobile 6 SDK
thanks

Have a look at the first post of my OpenGLES test app(check my sig) and try to run this app (take the latest one). There is also a link to a thread about a driverpack (v3 has just been released). Just to be sure that your device has some OpenGLES capable drivers.
AFAIK the hologram app uses d3d.
edit: The examples you mentioned create a rendering device using Red 8, Green 8, Blue 8 bits. Change them to 5, 6, 5 and try again. And don't copy their libgles_cm.dll to the device. Instead use the latest driverpack as described above.

Thank you, heliosdev
yes, i already tried your OpenGLES test app. it runs well also on my phone, but I don't understand C. do you have C code?
i try to modify the sample code following you instruction. but i failed. where am i wrong?

On your device there is no libgles_cm.dll at the place where your exe is, right?
Otherwise remove it from the directory where your exe is.
edit:
If it still doesn't start you could try to write out some messages during initialization (at the places before returning false).
Do you have libgles_cl.dll? In the code you have thes FixedFrom* calls.
You could try to remove all these calls, i.e. instead of FixedFromInt(i) just i and you'll have to change the x to i,f or d in the calls like Rotatex.

I copied the libgles_cm.dll file before from windows folder to Storage Card, where the exe file locates.
now I delete the libgles_cm.dll file , but nothing changes.

Hy,
maybe this can be a workaround for you!
http://cegcc.sourceforge.net/docs/faq.html#DllDoesNotWorkWithWindowsMobile6.1
------------------
Memory management changes in Windows Mobile 6.1 cause some DLLs not to load. It has been suggested (see this blog that the underlying problem is a writable code section in the DLL, other reports suggest that the DLL size may be an issue.
The workaround or solution (I'm not sure what to call it) that we have is to restrict this DLL to Slot 0 by adding the following registry key:
[HKEY_LOCAL_MACHINE\System\Loader\LoadModuleLow] "MyDll.dll"=dword:1
Obviously you need to change "MyDll" into the name of the DLL that causes the problem.
Please note that using the this approach will force your entire DLL into Slot 0 and, it may prevent other modules from loading in that slot. Therefore, the above registry setting should be used with caution.

thank you, mccoffein. that is a different idea.
But i think registry table is not the issue. Because the app can run on WM6.5 emulator, and heliosdev's OPENGL ES test app can run on my phone also.
I download glBenchmark 1.0 from glbenchmark.com, it can run also.
now I have no idea.

anyone can help me?

Got it
When I put my libgles_cm.dll in the same folder of my App, the App runs.
I think the libgles_cm.dll from HTC has some unknown problems.
Thanks

[GUIDE] Android Client-Server Communication (PHP-MYSQL REST API)

Hey XDA, this is my first guide and first proper contribution to the community!
I’m writing this because I've seen many people ask a variation of the question: “How can my app get information from a database?”
This guide is intended for those who have created their first app – it is assumed you have a working development environment and are reasonable comfortable with the Android SDK and Java. I'm also assuming little to no knowledge of PHP and MYSQL
This guide walks you through:
Setting up a database and a PHP script
Testing the server
Accessing it from Android.
To make it relevant, we're going to use data that we might see in an actual app: First & Last Name, Age and Points.
Requirements:
Android Device*
Computer*
Apache/PHP/MySQL Server – I use WAMP (for Windows) (PHP v 5.4)
Postman Rest Client for Google Chrome
(*Both must be connected to the same network!)
This guide will help you setup a local server. If you want to host your script and database online, you will have to purchase paid hosting.
Let's get started!
First off, what is a RESTful service?
According to Wikipedia: A RESTful web API (also called a RESTful web service) is a web API implemented using HTTP and REST principles.
How it works:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
A breakdown of the steps:
The client makes a request using a HTTP POST to a server
The PHP script queries the MYSQL server
The PHP script gets the SQL data
The PHP script puts the data into an array and assigns keys for the values. The script then outputs the data as a JSON array. JSON (JavaScript Object Notation) is a standard for data exchange, and formats the data in a way both humans and computers can easily read.
The app parses the JSON and displays the data.
Code!
Part 1: The Server
We’re going to start by setting up the server!
Install WAMP server. Leave the settings at the default values.
Start WAMP server and let it come online.
Try and open http://localhost/phpmyadmin/ - if you installed it correctly, you should be greeted by the phpMyAdmin welcome screen. We're going to be using phpMyAdmin to create our database.
Creating the Database:
Create a database called ‘mytestdatabase’. Now click the SQL tab, paste in the following SQL Code and hit run. This will create a test table called ‘users’ and fill it with data.
The table contains 5 columns: id, FirstName, LastName, Age, Points. It has 6 rows of sample data.
SQL Code:
Code:
-- phpMyAdmin SQL Dump
-- version 3.5.1
-- http://www.phpmyadmin.net
--
-- Host: localhost
-- Generation Time: Jun 15, 2013 at 10:07 PM
-- Server version: 5.5.24-log
-- PHP Version: 5.3.13
SET SQL_MODE="NO_AUTO_VALUE_ON_ZERO";
SET time_zone = "+00:00";
/*!40101 SET [user=714032]@old_[/user][email protected]@CHARACTER_SET_CLIENT */;
/*!40101 SET [user=714032]@old_[/user][email protected]@CHARACTER_SET_RESULTS */;
/*!40101 SET [user=714032]@old_[/user][email protected]@COLLATION_CONNECTION */;
/*!40101 SET NAMES utf8 */;
--
-- Database: `MyTestDatabase`
--
-- --------------------------------------------------------
--
-- Table structure for table `users`
--
CREATE TABLE IF NOT EXISTS `users` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`FirstName` text NOT NULL,
`LastName` text NOT NULL,
`Age` int(11) NOT NULL,
`Points` int(11) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=7 ;
--
-- Dumping data for table `users`
--
INSERT INTO `users` (`id`, `FirstName`, `LastName`, `Age`, `Points`) VALUES
(1, 'John', 'Doe', 25, 61),
(2, 'Glen', 'Willis', 55, 3145),
(3, 'Helen', 'Cook', 35, 1232),
(4, 'Karen', 'Johnson', 20, 6456),
(5, 'Bill', 'Cooper', 60, 3856),
(6, 'Mary', 'Gomez', 30, 5422);
/*!40101 SET CHARACTER_SET_CLIENT [user=714032]@old_[/user]CHARACTER_SET_CLIENT */;
/*!40101 SET CHARACTER_SET_RESULTS [user=714032]@old_[/user]CHARACTER_SET_RESULTS */;
/*!40101 SET COLLATION_CONNECTION [user=714032]@old_[/user]COLLATION_CONNECTION */;
Your database should now look like this:
We’re now ready to move on to the PHP!
Open up your WWW directory (C:\wamp\www) and create a new folder called ‘clientservertest’. In this folder, create a file called ‘login.php’.
Paste the following code into the file. (The PHP code is commented so you can follow what is going on)
PHP:
<?php
#Ensure that the client has provided a value for "FirstNameToSearch"
if (isset($_POST["FirstNameToSearch"]) && $_POST["FirstNameToSearch"] != ""){
#Setup variables
$firstname = $_POST["FirstNameToSearch"];
#Connect to Database
$con = mysqli_connect("localhost","root","", "mytestdatabase");
#Check connection
if (mysqli_connect_errno()) {
echo 'Database connection error: ' . mysqli_connect_error();
exit();
}
#Escape special characters to avoid SQL injection attacks
$firstname = mysqli_real_escape_string($con, $firstname);
#Query the database to get the user details.
$userdetails = mysqli_query($con, "SELECT * FROM users WHERE FirstName = '$firstname'");
#If no data was returned, check for any SQL errors
if (!$userdetails) {
echo 'Could not run query: ' . mysqli_error($con);
exit;
}
#Get the first row of the results
$row = mysqli_fetch_row($userdetails);
#Build the result array (Assign keys to the values)
$result_data = array(
'FirstName' => $row[1],
'LastName' => $row[2],
'Age' => $row[3],
'Points' => $row[4],
);
#Output the JSON data
echo json_encode($result_data);
}else{
echo "Could not complete query. Missing parameter";
}
?>
Testing the Script:
Try accessing http://localhost/clientservertest/login.php from your browser. Do you get this message:
"Could not complete query. Missing parameter"
Then it’s working! The script is looking for a POST variable called “FirstNameToSearch” – we didn't provide any, so it did't work!
To finish testing the script, open the Postman-REST client.
Set it up like so:
Request URL: http://localhost/clientservertest/login.php
Type: POST
Key: FirstNameToSearch
Value: John
Hit send, and you should see this:
Code:
{"FirstName":"John","LastName":"Doe","Age":"25","Points":"61"}
Congrats – your server just returned a result! Try some of the other names in the database (Glen, Helen, Karen, Bill, Mary) and see how their data is returned.
Note: Before we move on to the Android section, we’re going to have to put our WAMP server online. Click the WAMP icon in the taskbar and select 'Put Online'.
Find your computers local network IP address and insert it into the URL like so: http://192.168.1.112/clientservertest/login.php
You should be able to access the script. If this doesn't work, try turning off your firewall - it could be blocking the server.
Part 2: Android
We’re now going to use our Android device to access the web server instead of the Postman client.
I'm not going to go into detail with the boilerplate UI code - I've attached the source code to this post so you can download the project files and browse through them.
Note: Android 3.x+ cannot perform Network operations on the main thread. To solve this, we have to multithread our program. To keep this as simple as possible, we’re going to use an AsyncTask. Again, the code for this can be found in the project download.
Inside of the AsyncTask, we have the most important code - where we create and execute a HTTP POST in Java.
Creating and Executing a HTTP POST in Java:
We have to first setup the name-value pairs for our POST variables. In this case, we use "FirstNameToSearch" as our Key.
Code:
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("FirstNameToSearch", strNameToSearch));
The following code sets up connection timeouts (15 seconds) and creates a HttpClient and HttpPost pointing to our url (http://192.168.1.112/clientservertest/login.php)
Code:
//Create the HTTP request
HttpParams httpParameters = new BasicHttpParams();
//Setup timeouts
HttpConnectionParams.setConnectionTimeout(httpParameters, 15000);
HttpConnectionParams.setSoTimeout(httpParameters, 15000);
HttpClient httpclient = new DefaultHttpClient(httpParameters);
HttpPost httppost = new HttpPost("http://192.168.1.112/clientservertest/login.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
The following code executes the POST, gets the result and converts it to a string:
Code:
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
String result = EntityUtils.toString(entity);
Finally, the following code creates a JSON object from the result string and extracts our data:
Code:
// Create a JSON object from the request response
JSONObject jsonObject = new JSONObject(result);
//Retrieve the data from the JSON object
strFirstName = jsonObject.getString("FirstName");
strLastName = jsonObject.getString("LastName");
intAge = jsonObject.getInt("Age");
intPoints = jsonObject.getInt("Points");
That's it. It's so simple!
Where do we take it from here?
This combination of PHP/MYSQL is quite powerful. I'd recommend that you learn more about these technologies and build upon the demo in this guide. PHP Tutorials & MySQL Tutorials
Ideas for practice apps:
Online notes application - Sync your notes to the cloud
Build an Activation Server - Users can activate an app with a key

Thanks for this amazing guide but I have a issue.I have my own table and columns.So I changed your php code according to that and when I do a post query in rest,I get all null.But if I do the same in phpmyadmin,I have results.
This is what I get in postman:
Code:
{"pid":null,"name":null,"UID":null,"mobile":null,"description":null,"created_at":null,"updated_at":null}
attached the output of phpmyadmin.
And my phpcode:
Code:
<?php
#Setup variables
$firstname = $_POST["FirstNameToSearch"];
#Avoid SQL injection attacks
$firstname = mysql_real_escape_string($firstname);
#Connect to Database
$con = mysql_connect("localhost","user","pass");
if (!$con)
{
die('Could not connect');
}
#Select the test database
mysql_select_db("mydb", $con);
#Get the user details from the database
$userdetails = mysql_query("SELECT * FROM mytable WHERE name = '$firstname'");
#Catch any errors
if (!$userdetails) {
echo 'It seems the server is down.Please try later';
exit;
}
#Get the first row of the results
$row = mysql_fetch_row($userdetails);
#Build the result array (Assign keys to the values)
$result_data = array(
'pid' => $row[1],
'name' => $row[2],
'UID' => $row[3],
'mobile' => $row[4],
'description' => $row[5],
'created_at' => $row[6],
'updated_at' => $row[7],
);
#Output the JSON data
echo json_encode($result_data);
?>
Thanks for help.
Edit: just found that your app is missing internet permission in manifest
Code:
<uses-permission android:name="android.permission.INTERNET" />

:thumbup:
Thanks so much for this. I will try it out soon.

I was able to reproduce the null result - it means that the result was not available in the database. You'll want to double check the value you are passing to the script in Postman. (When I used 'FirstNameToSearch' and 'test' - I got a correct result. However, when I used 'testa', I got a null result.)
You can try adding this into the PHP script to catch this problem:
Code:
#Get the first row of the results
$row = mysql_fetch_row($userdetails);
[B]#Check to see if a result was returned.
if(!$row){
echo 'User does not exist';
exit;
}[/B]
I also noticed a few things in your PHP script:
In your screenshot, your table name appears to be 'Myapp', however in your PHP script, it looks like you are using 'mytable'
When you build the result array at the end, you are trying to access a column that doesn't exist:
This code tries to access an 8th column/index:
Code:
'pid' => $row[1],
'name' => $row[2],
'UID' => $row[3],
'mobile' => $row[4],
'description' => $row[5],
'created_at' => $row[6],
'updated_at' => $row[7],
You only have seven columns, so it should be:
Code:
'pid' => $row[0],
'name' => $row[1],
'UID' => $row[2],
'mobile' => $row[3],
'description' => $row[4],
'created_at' => $row[5],
'updated_at' => $row[6],

Now that's interesting.. I've never experienced a problem with that before.
I took a look at the PHP docs and found that mysql_real_escape_string() is depreciated - that could be contributing to the problem. I'll investigate this further and adjust the guide as necessary.
Thanks for sharing your solution!.

Maybe you are using ancient php module .BTW Can I also put data into tables using your php and slightly modifying "mysql_query" and using post?Or should I use put along with mysql_query?If later is the solution,could give me the snippet of how a put variable looks?because I dono php and I was waiting for someone to write this guide because before I was connecting to db with JDBS which isnt safe.Thanks and sorry for the trouble.
Edit: I got it to work like I said.But only issue is the created at and updated at time stamp which is not the part of php nor the app.I will correct it from mysql.Thanks once again.Will be happy to trouble you soon lol...No dont take it serious BTW

Do post() in async because it has to do http request which needs to be done in another thread.

Thanks, I figured out and got the code page of our glorious forum

I'm having an issue while testing the Query... I'm using Firefox and using RESTClient for debugging... and testing whatever value, db always responds null (See attachment)...

Exactly what I experienced first time.Try after commenting the line which prevents mysql injection and see if it works.If you run latest mysql,the chances are probably that its the issue

Already tried that... No go... Had to write the whole thing using w3schools example code as base... Just resolved a couple minutes ago and completed the project (it can be viewed @ Github:CardManager (App) and cardmanager_json (Web Service, only principal.php is the one handling the whole thing))...
Maybe a good add to the tutorial would be to have a config.php file with the user, passwd, database and table data calling it through require_once()... The DBConexion and DBGestion files (in my github) are supposed to do that, but didn't work either (hence doing the principal.php code all over again)...

Interesting.. I'll take a look at at your script, revisit the W3 tutorials, and then re-write mine. It's really rudimentary and tends to fail easily. I wanted to write about the config.php, however, I also wanted to keep this guide as simple as possible for newer users. Maybe I'll add in an advanced section.
I'll update the guide in a few days, as I'm right in the middle of exams :/
Thanks for the feedback!

[HELP] Native Toast Launcher

I was able to install the HTC Sprint Diagnosis app on my Nokia Lumia 1520 and also have the HTC CSDDiag app installed.
Interesting Part : I was able to run CSDDiag on the Lumia handset and all tests were completed.
Now what i would like to know is how do i run this code in the Native Toast Launcher :

However I would like to run the Dialer commands to see if I can mod anything else on the phone. Could some with good brain explain how this will be possible.
I have tried install other platform Diag tools but was only able to install the two above using fiddler ( thanks ngame for your tutorial )

Who did you do that ? I Try it many times before to install these aps on RM-821 Nokia Lumia 920 but didn't work !
how did you do that ? Could you please P.M Me ?

It wasnt hard to install those apps. Just followed the fiddler tutorial posted.
Then I connected the phone and installed SysPushApp onto the device and did an update for the SysPushApp to get the non_OEM files of Samsung and HTC . I couldnt install Samsung Diagnosis as it wasn't letting nor was I able to install HTC Hub ( I dont know why, may be they check some .dll specific to them in the phone before install ) .
Change the oSession in fiddler config file to the specific OEM you want to install the app. Example for HTC[ ->
oSession (NOKIA)
(NOKIA), (HTC) /B]
Mt device is Dev-Unlock.

Samsung diagnosis already removed from wp store so you can't install it easy
and diagnosis you can see in store may different from one in Samsung phones! If you check file sizes you will get what i say
Most of HTC apps only can install ID_Resolution_HD720p and WVGA devices i don't know how is it possible to deploy them on 1080 devices
maybe MS accept this resolution for all apps because the old apps have to add 1080 support?

I don't have this xaps but you have to use .Net Reflector 8 or any .net Decompiler then u can see all hidden xamls after _default you have to enter a #/ then dll name without it's dll them a ; and then folder and xaml address
example :
app://GUID/_default#/dllname;Pages/ExamplePage.xaml

OMG!!!!!!!! so many xamls !
If you can get a Screen Shot of each xaml is more useful I think

None of them works. We need to add Dialercodes in the end.

its alright mate.thanks for your help. I will try tomorrow.
did you check the xap's i posted in the other thread. I hope they will be useful. Thanks.
btw my phone came with Hong Kong firmware but I have installed the Australian firmware. Im glad atleast this was possible.

@nGage were you able to install those apps on your phone ?

@nGage there is some good news i was able to run the strings which you posted. It was all about changing 'Component' -> 'component' and some other tweaks. But the .dll library refers to something else and hence the data is not fetchable. I will post the screenshots tomorrow. @W_O_L_F can this file 'HTC Diagnostics_Sprint be hacked in any way as I was able to install this on Nokia 1520 via Windows App Store -> SysPush ( via Fiddler i.e chainging the OEMID=HTC )

Not for Nokia.

Be very careful with the HTC Sprint tool, since it has the ability to change NV values, even if it is commented out. (don't know why.) but it sure does.

thanks for the advice. But the app is pointless on Nokia phones as i have tried it and it doesn't work ... It can go to the menu's bit cannot get the values either it needs Interop or the dll linked is not for the device.

How to search StorageFiles

I need a way to search in StorageFiles with dynamically pattern, which comes from a TextBox. The directive "Windows.Storage.Search" doesnt exist in windows phone 8.1 runtime, as i saw. Now my question is, how can i do this in alternative way?

The only way to do it with WP 8.1 since Microsoft ALWAYS fails to implement the important things are to query using LINQ.
Ex:
Code:
var result = (await Windows.Storage.ApplicationData.Current.LocalFolder.GetFilesAsync(Windows.Storage.Search.CommonFileQuery.OrderByName)).
Where(x => x.Name.
Contains(x => txtBox.Text));
That's about all you can do pretty much. (Thanks Microsoft).

Thank you for the example. But it wont work for me, it shows me the following error(s):
Code:
A local variable named 'x' cannot be declared in this scope because it would give a different meaning to 'x', which is already used in a 'parent or current' scope to denote something else
and
Code:
Cannot convert lambda expression to type 'string' because it is not a delegate type
Thats really odd from Microsoft, that they havent implementet the search function like in WinRT (Windows Store App).

The first error is pretty simple. You already have the variable named "x" and it would be very bad if compiler didn't give you that error.
Change the name of the variable to something else that you don't use in that scope and it will work.
And for second problem, try this one:
Code:
private List<string> Result()
{
var result = ((List<Windows.Storage.Search.CommonFileQuery>)Windows.Storage.ApplicationData.Current.LocalFolder.GetFilesAsync(Windows.Storage.Search.CommonFileQuery.OrderByName)).Where(x => x.ToString().Contains(txtBox.Text));
return result as List<string>;
}
private async Task<List<string>> ResultAsync()
{
return await Task.Run(() => Result()).ConfigureAwait(continueOnCapturedContext: false);
}
You should call ResultAsync method and get the result in this way:
Code:
List<string> myList = ResultAsync().Result;

That's not going to work. You can't cast a StorageFile as a string.
To fix my code (simple lambda typo)
Code:
var result = (await Windows.Storage.ApplicationData.Current.LocalFolder.GetFilesAsync(Windows.Storage.Search.CommonFileQuery.OrderByName)).
Where(x => x.Name.
Contains(txtBox.Text));
if(result.Any())
{
// Do shtuff
}
Also, you should never access the .Result of an async task because you never know if it completed yet.

Ok, first error is done, but the second error is still here
Code:
Cannot convert lambda expression to type 'string' because it is not a delegate type

You are missing the point of the TAP (Task Async Pattern).
Both main thread and async method will be in execution in the same time. When the async method finish his work, main thread will stop and catch the result trough the Result property.
TAP is the recommended way of asynchronous programming in C#. The only thing with TAP is to use ConfigureAwait method in non-console type of apps to avoid deadlock.
Sooner or later you will get the result from TAP method. Nothing will get in the conflict with the main thread.

Oh wait, @andy123456 I updated my response. I forgot String.Contains ISNT a lambda .
@Tonchi91, I know all about the TAP. I've been using it since it was CTP. I've seen the awkward situations with threading in WP .

Now... if he did
Code:
List<string> myList;
ResultAsync().ContinueWith(t=> { myList = t.Result; });
I wouldn't be worried .

Ok the errors are gone, but the debugger show me the following exception:
Code:
Value does not fall within the expected range
Is this search method case-sensitive? I tried with an exact input in the TextBox.

Hmmm. Let's see your full code.

its actually only for testing, so i added your code to a button (asnyc) and will show the output in a textBlock.
Code:
private async void buttonTest_Click(object sender, RoutedEventArgs e)
{
//Result();
var result = (await Windows.Storage.KnownFolders.CameraRoll.GetFilesAsync(Windows.Storage.Search.CommonFileQuery.OrderByName)).
Where(x => x.Name.
Contains(textBox_test.Text));
if (result.Any())
{
// Do shtuff
textBlock_test.Text = result.ToString();
}
}
The error is coming from here
Code:
var result = (await Windows.Storage.KnownFolders.CameraRoll.GetFilesAsync(Windows.Storage.Search.CommonFileQuery.OrderByName))

Oh Camera Roll.. You MIGHT need to have the capability to view the camera roll enabled. I forget what it's called, but you need a specific cap in order to view from there. Also, I would try to see if you can use a generic folder instead.
I would try Windows.Storage.ApplicationData.Current.LocalFolder.GetFilesAsync() as your method after the await just to test whether you can read correctly.

Yes but in wp8.1 runtime app, there arent caps anymore. The capability for access to the pictures is simply calles pictures library and is enabled. I have tested it as you said, but it gives me the same exception.

A quick tip: another way to do this is to use the Win32 C runtime API. You can, for example, use the FindFirst/NextFile functions (http://msdn.microsoft.com/en-us/library/windows/desktop/aa364418(v=vs.85).aspx) which support searches using wildcards (* and ? characters in the first parameter). These functions are wrapped in my NativeLibraries classes, but are also just publicly available for third0party developers to call from their own C++ DLLs.
Alternatively, you can use the .NET System.IO.Directory class, which has functions like EnumerateFiles(String path, String searchPattern). This is probably the better way to do it, actually.
Of course, if you want these operations to not block the current thread, you'll need to explicitly put them in their own thread or async function.
EDIT: This also assumes you have read access to the relevant directories. You application data directory works fine, for example (you can get its path from the relevant StorageFolder object). Other directories that can be accessed via WinRT functions may go through a broker function instead of being directly readable.

The point is, that i have an array with filenames. Now i need the StorageFile files which contains these filenames. My idea was to search for these files and return the files as StorageFile, so i can work with these. Or is there a simpler / another way?

http://msicc.net/?p=4182 <-- try this

Thank you, i have already done this and its working. But how can i compare the Files to read, with already read files and take only the not yet read files?
