hi All,
I am developing using C#, .net CF2.0, WinCE5.0.

Does anyone know a C# .NetCF2.0 equivalent I can use for the 
Graphics.CopyFromScreen method?

I need to capture an area of my window in order to manilpulate the pixels..

thanks.

Something like this?

Thank you for that. 
I can see how this will work very well, however I seem to the following issue:

When I added the interop declarations into my code, all my custom controls 
were 'greyed' out in the form designer.....? Wierd.
As soon as i commented out the code :
/*
DllImport("coredll.dll")]
public static extern int BitBlt(IntPtr hdcDest, int nXDest, int nYDest, int 
nWidth, int  nHeight, IntPtr hdcSrc, int nXSrc, int nYSrc, uint dwRop);
   */
my controls were visible again in the form.
Any ideas on why this is happening?


thanks again.

I address this very topic in a previous blog entry regarding custom 
controls.

thanks for your responses so far.
I have not resolved the design time problem though. I have read your blog, 
but cannot find the file 'DesignTimeAttributes.xmta' you mention that allows 
the designer to display the control. (I am using Visual Studio 2005. ?).
What is even more concerning to me is that even if I declare a simple 
interop like this :
[DllImport("coredll.dll")]
private static extern uint GetTickCount();

within a DIFFERENT class than my control (but in the same namespace), which 
is not actually used at all, the designer still refuses to display all my 
existing controls (none of which employ any interops)...
I have also tried using the following code :
[DllImport("coredll.dll", EntryPoint = "GetTickCount")]
private static extern uint GetTickCountCE();

which does not work either.

Not sure where to go from here, any help is greatly appreciated.

thanks
