1.Wanted to receive the events,same like buttons.As my form is very small and needs to handle many events, I wants to use softkeys to reduce some buttons.
2.Wanted to make the form more colorful.Its Ok I managed to change the backcolor property.
3.Yes,I wanted to terminate the code by explicitly mentioning Applicatio.Exit but its just hanging,is there any other way to kill the process safely(programmatically)?
4.Yes,I have tried CAB program, but after successfully running in PDA,I just can't see my app in PDA?

Sorry for bugging you with so many doubts,thanks a lot.

1. I haven't tried this, but here is some code I found on the web: http://forums.devbuzz.com/tm.asp?m=38708&p=1&tmode=1[^]

2. Cool.

3. If your app is hanging after Application.Exit() gets called, then there is probably something else in your code keeping it from exiting. Are you using any threads or timers that aren't being terminated before trying to close the application? I have found that when I explicitly call Application.Exit(), it does in fact unload the app as I expect (or at least I've just assumed that and never checked to make sure Wink | ;-)

).

4. You will need to specify a shortcut in the "Start Menu" special folder. Take a look at this screenshot:

http://www.matthew-long.com/images/installer_properties.png[^]

You will also need to specify an icon for you application in the Application Properties like this:

http://www.matthew-long.com/images/app_properties.png[^]

Finally, you may want to soft reset your PDA. Icons get cached, so they need to be refreshed through a rest in order to show up correctly.

Let me know if you have further questions.

Let me try again on number 1. You said Soft Keys and I'm thinking the whole time you meant hardware keys. Anyhow, here is a little tidbit I found this morning on soft keys in Windows Mobile 5.0:

Adding smart keys to an application is as simple as designing a menu. When designing your application, simply create a menu with only two choices. When the application executes, Windows Mobile 5.0 will map each menu choice to a soft key. Windows Mobile 5.0 automatically provides this behavior to any application containing a menu with one or two choices. Menus containing more then two choices are rendered as a traditional menu.

I haven't tested this, but I got it from here: http://msdn2.microsoft.com/en-gb/library/ms839548.aspx[^]

Thanks a lot for your replies.
3.Yes, I am using System.Threading.Timers which triggers CallBack function events every few secs(Certain time interval) which is communicating with the server.We are using Timer.Dispose when App is closing but it not seems to be working, the requests are still going to server,thatmeans timer is running at the background.
I have used IDisposable interface to dispose the object possesing Timer, but its throwing StackOver flow Exception on disposing which cannot be handled even by Catch block.
After trying all the ways, I finally decided to Kill the Process Programmitically,what do you say?
In .NetFramework there is also a method called Environment.Exit but I cannot find it in .NetCompactFramework.
Please advise me..

The link you have given in 1 (regarding softkeys),page cannot found is coming,please resend.
Thanks again

I know this is stating the obvious but are you stopping the timer first before trying to call dispose? (just want to make sure).

Honestly, I think you really need to track down the real issue rather than trying to kill the process. Something is not right in the app and I promise it will not benefit you to just ignore the problem and try to kill the process. That being said, if you really want to kill it, take a look at Process.Kill() here: http://msdn2.microsoft.com/en-us/library/system.diagnostics.process.kill(VS.80).aspx[^]

Here's a note from that page:

The Kill method executes asynchronously. After calling the Kill method, call the WaitForExit method to wait for the process to exit, or check the HasExited property to determine if the process has exited.

I am not familiar with Envrionment.Exit(). You'll probably have to use something else, though, since it is not available in the compact framework.

And as far as the link in #1 goes, don't worry about it. If you see my previous post (where I respond to myself), you'll see that I was sending you to look at a link about hardware keys, not softkeys.

Hi perlmunger

Thanks a lot for your advises,they are very useful for us , I will avoid using Kill method and try to trace out the wrong thing in my App.
I will get back to you if any doubts.

1. There is codeproject article on capturing hardware key events.

2. You can add a background image to a form by overriding the paint event and using GDI to draw a bitmap on the form. I do this.

3. me.close, then application.exit
If you still have the problem use the debugger to see if the application is hanging during the form's dispose event and determine which object is causing the problem.

Fullscreen SIP input (draw on screen with mouse hook, like Transcriber)

apollo854-Feb-07 4:02

4-Feb-07 4:02

I develop own SIP (Soft Input Panel) which should have an opportunity to recognize the symbols drawn on all screen. Like Transcriber, but only for separate symbols. Has collided with 2 problems:
1) Interception of mouse events (can't set global hook)
2) If to draw on screen: GetDC(0)... after drawing it is impossible to refresh screen.

First method (I also tried to use NULL instead of GetDesktopWindow() in all methods)
#define SetWindowRedraw(hwnd, fRedraw) \
((void)SNDMSG(hwnd, WM_SETREDRAW, (WPARAM)(BOOL)(fRedraw),0L))
SetWindowRedraw(GetDesktopWindow(), TRUE);
RedrawWindow(GetDesktopWindow(), NULL, NULL, RDW_INVALIDATE |RDW_UPDATENOW |RDW_ALLCHILDREN);

Second method:
InvalidateRect(GetDesktopWindow(),NULL,FALSE);
UpdateWindow(GetDesktopWindow());

Third method:
RedrawWindow(GetDesktopWindow(),NULL,NULL,RDW_INVALIDATE|RDW_ALLCHILDREN|RDW_UPDATENOW );

Whether there are other ways of realization of drawing and recognition on all screen? Thought above creation of a topmost window with copying a contained desktop, but it would be desirable, all the same to make similarly Transcriber

How to send messages from icon on the upper toolbar ?

We are using SHNOTIFICATIONDATA to show icon on the upper toolbar on Windows
Mobile 5. But we can't find out how to send a message to our window when we
click on the icon, without showing any pop-up window.

Our code:

SHNOTIFICATIONDATA* pNotification = NULL;
HICON hIconn = NULL;

hIconn = AfxGetApp()->LoadIcon(IDR_MAINFRAME);

pNotification = (SHNOTIFICATIONDATA*)malloc(sizeof(SHNOTIFICATIOND ATA));

pNotification->dwID = ICON_ID;
pNotification->clsid = guidPPCAlertsApp; npPriority = SHNP_INFORM;
pNotification->csDuration = 10; hwndSink = m_hWnd; pszHTML =
pNotification->_T("...");
pNotification->hicon = hIconn;
pNotification->cbStruct = sizeof(SHNOTIFICATIONDATA); pszTitle =
pNotification->TEXT("Application name"); grfFlags = SHNF_STRAIGHTTOTRAY;

SHNotificationAdd( pNotification );

Hi guys

have been asked to do some maintenance on a mobile app in VS 2005

when i build and runthe app the emulator fires up and reports the following error

"This application (Mytestapp.exe ) requires newer version of the Microsoft .net compact framework than the version installed on this device"

is there a fix for this?
i tried getting the .NET Compact Framework 2.0 Redistributable however it wont install onthe PC when it has VS 2005 on it (!)
how do i work around this issue as i dont have a physical device to use?

cheers

Dear Bryce - read the interweb

f you have VS 2005 installed and are developing the app then just connect to the device in VS and deploy it. Make sure your project properties has the
"Deploy the latest version of the .NET Compact Framework (including service packs)" checked. It is found under "Devices".

You must use eVC 3.0 and an appropriate SDK for debugging/deployment on Windows CE 3.0-based devices. eVC 4.0 only works with CE 4.0 or later devices (you need at least SP1 for CE 4.1, SP3 for CE 4.1 and 4.2, and SP4 for CE 4.1, 4.2 and 5.0 - SP2 added 4.2 support but removed support for 4.1!) There were some changes in the OS's debugging support between v3.0 and 4.0.

It's recommended to install eVC 3.0 before 4.0 if you have the choice, but it should work if you install 3.0 after 4.0.

Download eVC 3.0 from here[^]. That includes the Pocket PC 2002 SDK.
