I'm just going crazy trying to get full-screen mode to work with the Touch Pro. Windowed mode works as expected (black screen, or whatever color I Clear to), but full-screen just does nothing at all. No exceptions are thrown (all the calls are supposedly working fine), but all I see on the screen is the white form background.
I'm using C# and DirectX Mobile. The project is targeting Windows Mobile 6 Professional. Here's the entire code of the only source file in the project:
Code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using Microsoft.WindowsMobile.DirectX.Direct3D;
using Microsoft.WindowsMobile.DirectX;
namespace Tilt {
public class frmMain : Form {
[MTAThread]
static void Main() {
frmMain f = new frmMain();
f.InitializeGraphics();
f.Show();
while (f.Created) {
f.Render();
Application.DoEvents();
}
f.DisposeGraphics();
}
public Device device;
public bool Created;
protected bool InitializeGraphics() {
Created = true;
PresentParameters p = new PresentParameters();
p.SwapEffect = SwapEffect.CopyVSync;
p.Windowed = true;
/*
* For some reason, these settings allow the device to be created,
* but nothing gets drawn (the form's white background is just shown
* full-screen). WTFmate?
DisplayMode dm = Manager.Adapters.Default.CurrentDisplayMode;
p.Windowed = false;
p.BackBufferWidth = dm.Width;
p.BackBufferHeight = dm.Height;
p.BackBufferFormat = dm.Format;
*/
device = new Device(0, DeviceType.Default, this, CreateFlags.None, p);
return true;
}
protected void Render() {
device.Clear(ClearFlags.Target, Color.Black, 1.0F, 0);
device.BeginScene();
device.EndScene();
device.Present();
}
protected void DisposeGraphics() {
device.Dispose();
}
}
}
Any help would be greatly appreciated!

OK I am writing my first Mobile 6 App, based on compact framework 2, obviously finding some differences from Framwork vs compact when dealing with reading and writting simple values to xml;
Here is what I want to do: write two textbox values to xml as follows:
<settings>
<hostip>192.168.0.14</hostip>
<hostport>8011</hostport>
</settings>
So I got the above accomplished using the following code:
--------------------
string hstip = "";
string hstport = "";
hstip = this.HostIP.Text.ToString();
hstport = this.HostPort.Text.ToString();
XmlWriterSettings xml_settings = new XmlWriterSettings();
xml_settings.Indent = true;
xml_settings.OmitXmlDeclaration = false;
xml_settings.Encoding = Encoding.UTF8;
xml_settings.ConformanceLevel = ConformanceLevel.Auto;
using (XmlWriter xml = XmlTextWriter.Create(GetApplicationDirectory() + @"\settings.xml", xml_settings))
{
xml.WriteStartElement("settings");
//xml.WriteStartAttribute("hostip", "");
xml.WriteElementString("hostip", hstip);
//xml.WriteString(hstip);
//xml.WriteEndAttribute();
xml.WriteElementString("hostport", hstport);
//xml.WriteStartAttribute("hostport", "");
//xml.WriteString(hstport);
//xml.WriteEndAttribute();
xml.WriteEndElement();
//ds.WriteXml(xml);
xml.Close();
}
-----------end of write code------------
Now the part I am stumped on as I have tried all varietions to get the data back into the textboxes, I either get and exception or blank values in the textboxes.
Here is the code:
------------------
private void SrvSettings_Load(object sender, EventArgs e)
{
XmlReaderSettings xml_settings = new XmlReaderSettings();
xml_settings.IgnoreComments = true;
xml_settings.IgnoreProcessingInstructions = true;
xml_settings.IgnoreWhitespace = true;
xml_settings.CloseInput = true;
try
{
using (XmlReader xml = XmlTextReader.Create(GetApplicationDirectory() + @"\settings.xml", xml_settings))
{
xml.ReadStartElement("settings");
xml.Read();
xml.ReadElementString(,,)
//xml.ReadToFollowing("hostip");
this.HostIP.Text = xml.GetAttribute("hostip","");
//this.HostIP.Text = xml.GetAttribute("hostip");
//xml.ReadToFollowing("hostport");
this.HostPort.Text = xml.GetAttribute("hostport","");
// Close it out----------------
xml.ReadEndElement();
xml.Close();
//ds.ReadXml(xml);
// }
}
}
catch (Exception ex)
{
System.Windows.Forms.MessageBox.Show(
ex.ToString(), "Error Loading IP settings");
}
}
------------end of read code
obviously I get an exception with this:
"System.xml.xmlexception:
"Text" is an invalid XmlNoteType. Line 2, posistion 11 at
System.xml.xmlReader.ReadEndElement()"
-----
I suspect I need to use ReadElementString, but I have tried and no workie...
Somebody have an example/class for both reading and writing per my requirements above, I would really appreciate the help..
Use XmlDocument
Try using the XmlDocument instead. It's alot easier to use for simple xml reading/writing.
Well Partially working now - I get the Hostport populated but for some reason hostip is blank even though it appears it falls through it in the case statement.. wierd..
DataSet ds = new DataSet();
XmlReaderSettings xml_settings = new XmlReaderSettings();
xml_settings.IgnoreComments = true;
xml_settings.IgnoreProcessingInstructions = true;
xml_settings.IgnoreWhitespace = true;
xml_settings.CloseInput = true;
try
{
using (XmlReader xml = XmlTextReader.Create(GetApplicationDirectory() + @"\settings.xml", xml_settings))
{
xml.MoveToContent();
xml.ReadStartElement("settings");
while (xml.Read())
{
//xml.Read();
switch (xml.Name)
{
case "hostip":
HostIP.Text = xml.ReadString(); <--I get Blank text
break;
case "hostport":
HostPort.Text = xml.ReadString(); <--POpulated OK
break;
default:
break;
}
// Close it out----------------
//xml.ReadEndElement();
}
xml.Close();
//ds.ReadXml(xml);
// }
}
}
Solved, Had to remove the line: xml.ReadStartElement("settings");
Thanks..
Just out of curiosity, what will your app do ?
I'm writing a WPF Windows App that monitors Server Services, IPs, Websites for up or down status; buiding a client server component to it, so the end goal will be to use the mobile app to connect to the host and download status on said servers being monitored and populate them in a listview whith thier up or done status.
Simple app but still in the works.
if you can make it customizable (to set up parametres, adreses) it wil be useful for many website administrators
a cool little app

Thanks for answers,
Scuse my bad english :-/
Not sure this helps, but RLTODAY works very well with transparent pngs in any WM version, and recently he released the source code:
http://rotlaus-software.de/forum/index.php?topic=1847.0
You can use ImagingFactory in OpenNETCF or other wrapper over the internet. PNGs with alpha work work for me.
AlphaControls
There is a project on Codeplex that can help you with transparency called AlphaControls. Also have a look on codeproject at the iPhone app clone

I tried OpenNetCF, without any result.
Do you have a piece of code in example ?

Can someone make a .cab or an .exe program to calculate Weight Watchers points? I found this article on the internet where it looks like someone as already done it but they did not post it. Here is the article
http://geekswithblogs.net/cdahlinge...-mobile-meets-weight-watchers--mvp-style.aspx
Craig Dahlinger
<< Presenting at Richdmond code camp 2008.2 | Home | mshtml – the ongoing adventure >> windows mobile meets weight watchers : MVP style Ok, so I know it has been a long time since a post, but it has been really busy with work and family. I have been busy coding and learning lots of new stuff. I work with a great bunch of developers and my current team lead is a great mentor.
Well for the new year the wife and I decided to get back into shape. I started hitting the gym and so did she but she is also doing weight watchers with a friend. One of the things they do is they have to calculate points on a daily basis. These points are comprised of calories, fat and fiber. There is a formula for these three which in turn results in the number of points a particular item is. A few months ago I convinced the wife to get a windows mobile device (woo hoo!) and she is a good power user. So one night she asks me, “Is there a way I can just enter in the calories, fat and fiber on my phone and it tell me how many points something is?”. I did some searching and there are numerous online versions of the calculator but no native ones for windows mobile. I found the formula here, and started to get to work.
I wanted to approach this application using the MVP design pattern. I know it may be overkill for this simple of an application but I thought it would be good practice.
I started with the interface for the data model, in this case it would be the main caloric properties of food.
namespace WWPC.Common.Interfaces{ public interface IFoodModel { int Fiber { get; set; } int Calories { get; set; } float Fat { get; set; } int Points { get; set; } int CalculatePoints(); }}I then wrote up the interface for the view for the model.
namespace WWPC.Common.Interfaces{ public interface IFoodCalcView { int Calories { get; } int Fiber { get; } float Fat { get; } int Points { set; } event EventHandler DataChanged; }}Next, came the interface for the presenter.
public interface IFoodCalcPresenter { void OnCalculatePoints(); }
Ok, now that I got my main interfaces in place, time to code up the implementation. I started with the model first since this was the class that would provide the implementation for calculating the caloric points. Using the formula mentioned above, the CalculatePoints() method came out like so:
public int CalculatePoints(){ var calories = Convert.ToDecimal(Calories); var cal = calories / 50; var totalFat = Convert.ToDecimal(Fat); var fat = totalFat / 12; var fiber = Convert.ToDecimal(Fiber); return Points = Convert.ToInt32(Math.Round(cal + fat - (fiber/5), 0)); } With the model complete, I then moved to the presenter. The presenter would be responsible for binding the model to the view responding to the data changes in the view and rebinding those changes to the model. I made the presenter with an overloaded constructor to take a view and a model. The presenter then binds to the data changed event on the view which enables the presenter to update the model from the view. The OnCalculatePoints() method will update the view with the points value after using the model for calculation.
namespace WWPC.Common{ public class FoodPresenter : IFoodCalcPresenter { private readonly IFoodCalcView _View; private readonly IFoodModel _Model; public FoodPresenter(IFoodCalcView view, IFoodModel model) { _View = view; _View.DataChanged += new EventHandler(_View_DataChanged); _Model = model; } void _View_DataChanged(object sender, EventArgs e) { SetModelFromView(); } private void SetModelFromView() { _Model.Calories = _View.Calories; _Model.Fat = _View.Fat; _Model.Fiber = _View.Fiber; } #region IFoodCalcPresenter Members public void OnCalculatePoints() { _View.Points = _Model.CalculatePoints(); } #endregion }}
With the presenter done it was time to implement the view. I wanted a simple mobile form where you can enter in data quickly and then calculate the results. I initially tried using a label to display the result, but did not like it. I then tried a mobile gauge control, but that took up too much space on the small screen. Finally I decided to use the notification class for windows mobile. I did not use the managed wrapper version, I used the the version created by Christopher Fairbairn, found here. This version has an awesome implementation which exposes many features of the notification class. I wanted to give the user the ability to dismiss the notification when they were done reading the results. Also using the notification class the UI was able show the needed text boxes for entry and the SIP panel along with the results without needing to scroll the screen. Here is a screen shot of the main form.
Now with the controls in place on the form, I can implement the view. The form creates a new presenter and passed into it a new model during construction. When the calculate menu option is clicked the main form raises the data changed event then calls the OnCalculateMethod on the presenter. When the presenter binds the model to the view, during the set of the points value, the notification is shown to the user via the ShowNotification method.
namespace WWPC.Calc{ public partial class WWPCalculator : Form, IFoodCalcView { private readonly FoodPresenter _Presenter; private NotificationWithSoftKeys _Notification; public WWPCalculator() { InitializeComponent(); _Presenter = new FoodPresenter(this,new FoodModel()); } public int Calories { get { return (string.IsNullOrEmpty(txtCalories.Text)) ? 0 : Int32.Parse(txtCalories.Text); } } public int Fiber { get { return (cmbFiber.Text == "4 or more") ? 4 : (string.IsNullOrEmpty(cmbFiber.Text)) ? 0 :Int32.Parse(cmbFiber.Text); } } public float Fat { get { return (string.IsNullOrEmpty(txtFat.Text)) ? 0 : float.Parse(txtFat.Text); } } public int Points { set { ShowPointsNotification(value); } } public event EventHandler DataChanged; private void mnuExit_Click(object sender, EventArgs e) { this.Close(); } private void mnuCalculate_Click(object sender, EventArgs e) { if (DataChanged != null) this.DataChanged(sender, e); _Presenter.OnCalculatePoints(); } private void mnuClear_Click(object sender, EventArgs e) { txtCalories.Text = string.Empty; txtFat.Text = string.Empty; cmbFiber.Text = "0"; } private void ShowPointsNotification(int points) { _Notification = new NotificationWithSoftKeys { Text = String.Format("Total Points:{0}", points), Caption = "Weight Watchers Point Calculator", RightSoftKey = new NotificationSoftKey(SoftKeyType.Dismiss, "Dismiss"), }; _Notification.RightSoftKeyClick+=new EventHandler(_Notification_RightSoftKeyClick); _Notification.Visible = true; } void _Notification_RightSoftKeyClick(object sender, EventArgs e) { if (_Notification == null) return; _Notification.Visible = false; _Notification = null; } }}
Now, when it is all put together, it looks like so.
Below is a link to the source code. The project was done using Visual Studio 2008 against the windows mobile 5 sdk. It will also work against windows mobile 6 sdk, I just chose version 5 since that is the common sdk. Thanks for reading!!

Try using an LruCache or your images. Also, you might want to take a look at this guide explaining it further.

Hi,
i develop a map-app and want to implement google maps search
i get following build error
"error: package com.google.android.maps does not exist"

You need to add a reference to the maps package in build.gradle

Apologies for the late reply, didn't get a notification from the thread.
Try removing the lines:
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.google.android.gmslay-services-maps:15.0.1
And add
implementation 'com.google.android.gmslay-services-maps:16.0.0'
If that doesn't work I'll draw up a demo app - this is a bit odd as I'm actually using maps in an app for my uni coursework and it's working fine
Edit: Also check that you have added the Google maven repo in the top level build.gradle file
