Hi Every Body,

i try to developin C# application in CASIO IT-500 device. TO make image
capture i need BeginPaint EndPaint functions. Anybody has idea how can we
user this functions.

thanks in advance.

What would these functions do? Control (and some derivatives) support
overriding OnPaint, so at the top would likely be "begin" and the bottom
"end".

CAMSingleCapture(TEXT(\\My Documents\\Picture.jpg),CAM_JPEG,CAM_VGA);

but evc encountered error like below

Well you're missing quotes, that's a start....

Hi ,
thank you for help, in weekend i try to implemet come c# code for beginpaint
functions.

public struct PAINTSTRUCT
{

public IntPtr hdc;
public int fErase;
public System.Drawing.Rectangle rcpaint;
public int fRestore;
public int fIncUpdate;
public Byte[] rgbReserved;
};

[DllImport("coredll", EntryPoint="BeginPaint", CharSet=CharSet.Unicode,
CallingConvention=CallingConvention.Winapi,SetLastError=false)]
public extern static IntPtr BeginPaint(IntPtr hwnd, ref PAINTSTRUCT pps);

[DllImport("coredll", EntryPoint="EndPaint", CharSet=CharSet.Unicode,
CallingConvention=CallingConvention.Winapi,SetLastError=false)]
public extern static IntPtr EndPaint(IntPtr hwnd, ref PAINTSTRUCT pps);

but when try this functions in form Paint evet it gives Not
supportedexception.

thanks in advance.

AZlright, now I see the function you were trying to call. I think at this
point it's better to ask what you're trying to achieve overall rather than
trying to debug your P/Invoke call. Exactly what behavior are you trying to
achieve? It may be possible without the call.
