Cold boot auto install

How would I go about performing an automatic installation of several .CAB files after a cold boot of the XDA 2? These CAB files will be located on a storage card and are part of a commercial package.
Thanks
Tony Hudson

One can create a "autorun.exe" in a folder called "2577" on the memorycard..
But I'm really not sure how...

you can auto install
by putting the updates in the extented rom
http://wiki.xda-developers.com/index.php?pagename=ER2003Edit
not sure how you would go about making them be able to be located on the sd card unless you put in a program in the extented rom
which would again auto install the cab files located on the sd card

I have wrote an eVC app for installing multiple .CAB files on an SD card. I am wanting the CAB files to be installed synchronously then the device to be warm booted so I am calling ShellExecuteEx to open the CAB file, WaitForSingleObject to determine when the CAB file has finished and then KernelIoControl to reboot the device.
The problem is that WaitForSingleObject is returning before the CAB file has closed with an error code of 6 which is invalid handle.
info.cbSize = sizeof(info);
info.fMask = SEE_MASK_FLAG_NO_UI;
info.hwnd = NULL;
info.lpVerb = _T("open");
info.lpFile = (LPCWSTR) &szCAB;
info.lpParameters = _T("");
info.lpDirectory = _T("");
info.nShow = SW_SHOW;
// Call to perform an action
ShellExecuteEx(&info);
if ((long)info.hInstApp > 32)
{
dwRetVal = WaitForSingleObject(info.hProcess, INFINITE);
switch(dwRetVal)
{
case WAIT_ABANDONED:
iErrCode = 4;
break;
case WAIT_OBJECT_0:
iErrCode = 4;
break;
case WAIT_FAILED:
dwErr = GetLastError();
iErrCode = 4;
break;
default:
iErrCode = 0;
break;
}
}
When running this in debug mode the CAB file being executed has presented the user with a dialog box prompting to overwrite existing files and the WaitForSingleObject has already returned.
Any suggestions?
Thanks.

Install From Storage Card on Insertion
This details info about autoinstalls from a SD card...
But the application is also uninstalled on removal of the card?
http://msdn.microsoft.com/library/d...P/html/sp_programming_pocket_pc_2002_balr.asp

Thankyou but I have already read this, and the above listing is a section of my autorun.exe application. This does not answer the problem I have documented above but thanks for taking time to assist me.

Just to outline, the problem that I am witnessing is that all the CAB files are being opened before the previous CAB installation has completed and the device is being warm booted without all the CAB files being installed. I need to wait in the looping code until a CAB file has completed its installation. The waitforsingleobject call should do this but it appears to fail. The CAB file has been opened succesfully but the error is that an invalid handle has been provided to the call. Thanks for any help

Doh! How stupid am I - please dont everyone reply. The programming error is in that I assign the return value of WaitForSingleObject to a variable. Change the above code snippet from
dwRetVal = WaitForSingleObject(info.hProcess, INFINITE);
to
WaitForSingleObject(info.hProcess, INFINITE);
and remove the switch..case code and it works fine.

Ok. So I now have my autorun.exe program that installs my CAB files but where do I put it in order for it to automatically install after a cold boot? I have tried the .EXE in "\storage card\2577" and in "\storage\2577" neither of them working. Modifying extended ROM is not an option here as this is a commercial package that is distributed on an SD card. I simply want the user to insert the SD card and then do a cold boot that will then install the CAB files. Is this possible and if so how? Thanks.

Got it all working now, the .EXE does go into the SD card subdirectory \storage card\2577.

HI,
Have you (or someOne else) tried to call registry keys (mostly interested in network connections) from this autorun.exe?
Herman

autorun?
what did you use for an autorun.exe??
is the code u put up earlier comilable to an autrun.exe?
(not a coder per se ,but dibble little here and there)
or is it from the sdk?
It it possible for u to post it as a attachment here?

The Autorun.exe file can be whatever exe file you want.

that I understand...but what if I wanna install more than 1 thing...I have a list of stuff I wanna do...like a couple of .cab and some .exe´s and maybe a .cpf.....how can I get them all to run automatically on cardinsert....
I gave the code to a programmer at work..I will see what he comes upp with...but I thinkthat there should be somekind of "public" autrun.exe with a .cfg file with it to download here at xda-dev.
If mine works I will post it later...

How to make Popup Message on CAB Files?

I received a CAB file from my friend, and when I tried to install it, I found that it has a popup message from my friend telling me a joke...
how he do that?
and how can I change that message?

Still No Comment...!
Please Help!

I asume you know how to make a cab to start with????
As you know there are exported functions in the dll that the cab uses (you make the dll). For example this is the normal look of whats exportd. Bellow is whats in the def file.
--------------------------------------------------------------------------
; TestSetup.def : Declares the module parameters for the DLL.
LIBRARY "TESTSETUP"
;DESCRIPTION 'TESTSETUP Windows CE Dynamic Link Library'
EXPORTS
Install_Init
Install_Exit
Uninstall_Init
Uninstall_Exit
now in the code for one of those you just make a dialog like normal.
The code below is cut out of one of my working cabs. Because its in Install_Init it is the first thing to happen. Changing the method to Install_Exit would give the message after the instalation.
#include "stdafx.h"
#include "TestSetup.h"
#include "ce_setup.h"
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif
#include "MyAboutDialog.h"
BOOL CALLBACK gAboutDialogProc(HWND h_dlg, UINT my_message, WPARAM wpAram, LPARAM lpAram);
static CMyAboutDialog* myAbout= new CMyAboutDialog();
BOOL CALLBACK gAboutDialogProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
return myAbout->AboutProc(hWnd,uMsg,wParam,lParam);
}

{
AFX_MANAGE_STATE(AfxGetStaticModuleState());
DialogBox:AfxGetInstanceHandle(),
MAKEINTRESOURCE(IDD_AboutDIALOG),
hwndParent,
(DLGPROC)gAboutDialogProc);
return codeINSTALL_INIT_CONTINUE;
}
//------------------------------------------------------------------
Of course the detail of the dialog is in the MyAboutDialog. You just make your own to do what you want.
You can do just about anything from the code you put in the cab's dll, but a lot of the instalation should be left up to cabwiz to generate. What ever you do put in the dll will permanently reside in the windows folder until the user removes the program, so don't make it too big.

Thanks Dear OdeeanRDeathshead...
your reply is more than an informative article.
however, I hope if you can answer my second part of the question...
how can I remove the message from a CAB file that i have?

I you want to remove the message on an existing cab then that is more complicated. If you know everything that the cab dose when it gets tapped (eg registry changes etc) then you could gather all the file that the cab installs and use them to re-write them into a new cab that has no messages. This is more trouble than its worth. Unless your friend is willing to give you detailed info on what his cab dose you would be bound to miss something.
Also many messages are as a result of the os, and these vary depending on the version of os. You can't stop some of those (on every platform).
Most people would not want their instalation packages tampered with.

Try to extract the .cab file with Win CE Cab manager. Remove the Setup.dll, hopefully it does not do anything else then showing the joke Then build your own version of it.

for any complex instalation I doubt that doing that would leave you with a working instalation. Still its worth a go if it saves time. What I would like to know (not having vis studio 2005 yet) is why dose the wm2005 device always ask where you want to put the software even when you have turned this feature off? When one's coding gets a bit lazy it can all fall appart when put in a location other than that you expect.

OdeeanRDeathshead, I assume you are referring to whether to install to main memory or to SD question (this dialog pups up on WM5 device with SD inserted or built in storage).
To avoid it remove the InstDir string from your inf file (or change the string name to something else). This will force the software installation to the directory you specify in the cab.

I did not want to hard code the directory, so I used
InstallDir="%CE2%"
That should get the location of the windows folder for the install. Are you saying that if I just put
InstallDir="\windows\"
it will force it there. Dose this mean that there is a new table of Windows CE Directory Identifiers or that installs just always ask if you use them?

No, what I meant was you don’t want a string call 'InstallDir' in your inf file.
The 'InstallDir' is just a string definition you may or may not use later in the inf (like #define in C).
What determines where the files are installed is what's in the [DestinationDirs] section.
For example:
Files.Windows = 0,%CE2%
You should delete the line InstallDir = completely from your inf file, or if this string appears else where (except [CEStrings] section) just change it to something like MyDir= (be sure to change it every ware it appears in the file)

[Q] How do i incorporate these code below into my current existing codes?

I was task to allocate only 1GB of space to store my videos in a particular file directory where it is going to auto-delete the oldest video file in that directory once its about to reach/hit 1GB?
And i eventually found these code but i was left with a problem on how to incorporate these example 1/2 codes into my current existing mainActivity.java file because of the differences in names like "dirlist,tempFile" compared with other examples 1/2 given to perform the task of size checking and deleting.
Sorry i'm kinna new in android/java therefore i don't really know what "fields" to change to suit my current coding needs? Can someone help on how am i going to complie these set of codes into a single set of code which perform the above mention functions??
My Current existing mainActivity.java
Code:
File dirlist = new File(Environment.getExternalStorageDirectory() + "/VideoList");
if(!(dirlist.exists()))
dirlist.mkdir();
File TempFile = new File(Environment.getExternalStorageDirectory()
+ "/VideoList", dateFormat.format(date) + fileFormat);
mediaRecorder.setOutputFile(TempFile.getPath());
(Example 1) code for summing up directory file size in a given folder..
Code:
private static long dirSize(File dir) {
long result = 0;
Stack<File> dirlist= new Stack<File>();
dirlist.clear();
dirlist.push(dir);
while(!dirlist.isEmpty())
{
File dirCurrent = dirlist.pop();
File[] fileList = dirCurrent.listFiles();
for (int i = 0; i < fileList.length; i++) {
if(fileList[i].isDirectory())
dirlist.push(fileList[i]);
else
result += fileList[i].length();
}
}
return result;
}
(Example 2) set of code for getting all the files in an array, and sorts them depending on their modified/created date. Then the first file in your array is your oldest file and delete it.
Code:
// no idea what are the parameters i should enter
// here for my case in mainActivity??
File directory = new File((**String for absolute path to directory**);
File[] files = directory.listFiles();
Arrays.sort(files, new Comparator<File>() {
@Override
public int compare(File f1, File f2)
{
return Long.valueOf(f1.lastModified()).compareTo(f2.lastModified());
}});
file[0].delete();

if its a matter of variable names and discrepancies from the sample code to your code then i would recommend an ide with really good refactoring built in. it will let you in a couple clicks rename all the new vars to vars that are already in your code. i use IntelliJ (i know alot of people use Eclipse, but i cant stand it. IntelliJ is really way better to code on)
beyond that id have to sit down and look at what this code is doing to try and help. ill give it a look over but its hard to know whats going on when you havent written the code.

Help Needed for changing String to File!!!

Hello, i just need to change a String i get from an Intent to a File so i can use listFiles().
The linecode that messes up is:
root = (File)extras.getString("newFilePath");
root is the File variable,
newFilePath is the extra i put in the Intent.
I know it could be a very easy solution but i'm out of ideas right now and i could use your help if you can help me. :cyclops:
Thanx in advance!!!

Hi!
You cannot cast file to string
Try this:
File root = new File(extras.get string("newFilePath"));

This.
Just to add: when declaring a file, the syntax is:
File foo = new File(<string>);
The string can be a regular (typed) string, or can be constructed as long as the result is a string.
e.g.
File foo = new File("C:\\MyDocs\\FileName.TXT");

Thanx very much both of u guys. Finally figured out and as i said it was so simple, but i'm not so experienced with Android or Java for that matter...
Now app works correctly

No directory shared_prefs

Good day.
Wrote an application that uses the class SharedPreferentses to store and retrieve settings. On the emulator works fine, but the device is not present.
After installing the application does not create a folder shared_prefs where it should be stored configuration file.
Please tell me why not create a configuration file?

Can you show us the piece of code where you instantiate sharedPrefs and the piece where you push values?
I think this will help to find the solution

Code:
public String loadProperty(String nameProp) {
SharedPreferences sPref = view.getSharedPreferences("Properties", Context.MODE_PRIVATE);
return sPref.getString(nameProp, "");
}
public void saveProperty(String nameProp,String valueProp){
SharedPreferences sPref = view.getSharedPreferences("Properties", Context.MODE_PRIVATE);
Editor editor = sPref.edit();
editor.putString(nameProp, valueProp);
editor.commit();
}

Hmmm...
Have you already tried to instantiate sPrefs inside onCreate instead of instantiate it every time you have to read a value?
Basically there are no errors here.
You can eventually call:
SharedPreferences.Editor editor = sPrefs.edit();
I think the problem is in the editor because shared preferences file will be created/modified when you commit changes and "Editor" could be a bad import (I don't think, but let's exclude obvious things first)
You can also try to use default shared preferences and see what happens :
SharedPreferences mPrefs = PreferenceManager.getDefaultSharedPreferences(context);

No that is not a problem, you can instantiate shared prefs as often and where you like. Only thing is that this may be bad for your performance but that is a diffferent question.
Another little thing: you should use editor.apply() instead of editor.commit(), as apply looks for the next best possibility to write the changes to the file instead of immediately doing this. But this also just helps performance, it isnt crucial
