We use the RequestPowerNotifications API. I thought there was a sample somewhere on MSDN but can't see it.

I am new to CE development and need to develop a database application that several ce devices will sync with a wireless server on job status for a custom manufacturing firm. The more I read on microsoft the more I'm confused...please help. What is the purpose of embeded? I've got Visual Studio 2005 and thought I could simply start writing...but it seems I have to work with the os and platform builder etc. I've got the Windows CE.net book by Douglas Bowling, but it is written for CE 3.0 and with older Visual Studio. I'm looking to knock this application out quickly...what is the fastest track to learn? Do I simply need to bite the bullet and watch all the embedded, OS, Platform builder tutorials? Or is there a faster track?
learning...

In my all forms where I have Images I get this error
"An error message cannot be displayed because an optional resource assembly containing it cannot be found"
when I try to open form.
Should I re-install anything ?

To save space, the error messages aren't included in the .NET Compact Framework CAB. If you need them, deploy System_SR_ENU.CAB from C:\Program Files\Microsoft Visual Studio 8\SmartDevices\SDK\CompactFramework\2.0\v2.0\WindowsCE\Diagnostics.

How can I get used Memory Size on my Pocket PC?

In C/C++, call GlobalMemoryStatus. For devices with RAM-based storage (i.e. Windows Mobile 2003 and older, custom CE platforms) call GetSystemMemoryDivision to find out how much space is allocated to programs versus data.
From .NET I think you currently have to use DllImport to call the above functions. See http://www.pinvoke.net/default.aspx/coredll/GlobalMemoryStatus.html[^] for details.

I'm looking to enter text in a textbox using only numeric keys (without holding down a seperate key to get it's numeric value). Like the phone dialer and the calculator.
Can someone point me in the right direction? VB or C# is fine. I have seen the Smartphone snippets, but they don't appear to work on the Pocket PC phone devices.
Any help would be appreciated.

In my Pocket PC application I set image gif animation and in run-time image doesn't appear animating.
How can i enable animating of gif image on runtime of application?

Hi,
out of the box the Compact Framework controls will not support animated gifs.
If you are able to use the OpenNETCE SDF library you may be able to utilise their OpenNETCF.Windows.Forms.AnimateCtl control for this purpose.
Otherwise you are probably best to extract the individual GIF frames and add them all as embedded resources into your application. you could then use a timer and a picture box to cycle through the images etc.
Hope it helps,
Christopher Fairbairn

Hi,
You may like to take a look at the thread over on MSDN Forums available here - http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1504457&SiteID=1[^].
This thread discusses this exact topic and covers some of the problems you may fall into. In short it will be reasonably difficult to obtain the exact UUID as used by ActiveSync etc. However if you just need to get an id which is unique to a given device and repeatable you can probably do what you want by using the GetDeviceUniqueId API call.
Hope it helps,
Christopher Fairbairn

As you might know, there's no "Clipboard" object in .NET Compact Framework 1.1 (target device PocketPC2002). However, i can access the clipboard through P/Invoke.
The thing is:
Declare Function SendMessage Lib "user32" Alias "SendMessageA" ( _<br />
ByVal hWnd As Long, ByVal uMsg As Long, _<br />
ByVal wParam As Long, ByVal lParam As Long) As Long
typical clipboard function call would be SendMessage(hWnd, WM_COPY, 0, 0). But i don't know how to obtain a handle of the TextBox control. Can someone help me?
i tried this solution, but it didn't work.
EDIT: Looks like i need a handle of an active window, so i get it through GetFocus(). I saw a hWnd as Long declaration somewhere, but it doesn't affect anything since IntPtr and Long are basically the same.
Here's my code:
<br />
...P/INVOKE<br />
Declare Function GetFocus Lib "coredll.dll" () As IntPtr<br />
Declare Function SendMessage Lib "coredll.dll" Alias "SendMessageA" ( _<br />
ByVal hWnd As IntPtr, ByVal uMsg As Long, _<br />
ByVal wParam As Long, ByVal lParam As Long) As Long<br />
...END P/INVOKE<br />
<br />
...SUB<br />
Dim hWnd As IntPtr<br />
hWnd = GetFocus()<br />
Try<br />
SendMessage(hWnd, WM_COPY, 0, 0)<br />
MsgBox("SUCCESS")<br />
Catch ex As Exception<br />
MsgBox("FAILED" & vbCrLf & ex.Message)<br />
End Try<br />
...END SUB<br />
Msgboxing hWnd returns a value (some integers, so this one works), but SendMessage fails throwing NotSupportedException. Any solution out there?
EDIT
i found a working solution!
the correct function declaration is:
Declare Function SendMessage Lib "coredll.dll" (ByVal hWnd As IntPtr, ByVal Msg As System.Int32, ByVal wParam As System.Int32, ByVal lParam As System.Int32) As IntPtr
This is the code for obtaining a handle of the control:
Public Function gethWnd(ByVal ctrl As Control)<br />
Dim hOldWnd As IntPtr = GetCapture()<br />
ctrl.Capture = True<br />
Dim hWnd As IntPtr = GetCapture()<br />
ctrl.Capture = False<br />
SetCapture(hOldWnd)<br />
Return hWnd<br />
End Function
This code requires two additional declarations:
Declare Function GetCapture Lib "coredll.dll" () As IntPtr<br />
Declare Function SetCapture Lib "coredll.dll" (ByVal hWnd As IntPtr) As IntPtr
And so the final message call will look like this:
SendMessage(gethWnd(CONTROL), WM_COPY, 0, 0)
and the constants declaration:
Public Const EM_CANUNDO = &HC6<br />
Public Const EM_EMPTYUNDOBUFFER = &HCD<br />
Public Const WM_COPY = &H301<br />
Public Const WM_PASTE = &H302<br />
Public Const WM_CLEAR = &H303<br />
Public Const WM_UNDO = &H304

target platform - WinCE 3.0 (PocketPC2002)
I need to handle the textbox caret position changes e. g. when i move caret somewhere something happens.
VB .NET (CF 1.1), eVB or eVC++ 3.0 - doesn't really matter, but preferrably something VB
Right now i'm working on a round-about method - to start a thread with infinite Loop sequence which checks the caret position and responds to it's value. But this is relatively slow and unstable...

Hi,
has anyone ever tried to access files in \Windows-Directory? Any attempt to open a file via CreateFile() return a WIN32-Error 5 (ERROR_ACCESS_DENIED) on my device! Microsofts Remote-FileViewer tool for CE fails too if an attempt was made to download a file from \Windows to my development-machine!
Does anyone know a solution?
Best regards
Reiner

DLL and EXE files in ROM can be of two sorts: execute-in-place, and regular files. DLLs and EXEs marked execute-in-place cannot be opened for reading, only loaded by Windows using CreateProcess or LoadLibrary. Files with other extensions may also be affected if they're really DLLs underneath (and are also marked execute-in-place).
Technical reason: a DLL or EXE's image on disk is different from its image in-memory. An execute-in-place DLL or EXE is exactly what it says: it executes directly, in-place, from the ROM. A 'regular' DLL file has to be copied to RAM and fixed-up by the loader; for the execute-in-place DLL, it has to be fixed-up at ROM build time. In the process, the information required to fix it up is discarded along with the regular image headers. It isn't then possible to reproduce the file. It could have been, but Microsoft decided not to waste ROM space on keeping the information required to reverse the process.
Execute-in-place was very relevant in the first Windows CE devices which had very small amounts of RAM. I think it's being slightly de-emphasized now.
Either type of DLL, and indeed any file in the ROM, can be overridden by copying a file to the device's storage in the 'same' location to shadow it. However, you can never delete the file.
