Dear,
Can I use BitBlt , and GetDC with ASP.NET?

Raed:
I don't know much about this, but hopefully can still help you. In .Net you
can easily interop with win32 native code...all you must do is import the
desired function into your code..

you'll see them importing BitBlt and GetDC and then use them later on..

I would tell you that I need to do this to be able to capture the Client
Desktop when an error is occured ,i did what came with link and do
private void Button1_Click(object sender, System.EventArgs e)
{

System.Drawing.Bitmap oBitmap = CaptureScreen.CaptureScreen.GetDesktopImage();
oBitmap.Save("C:\\test.jpg",System.Drawing.Imaging.ImageFormat.Jpeg);
}
the image is black,why?
other question is this possbile to get the client Desktop screeen using the
provide method

GetDC will take a screenshot of the server...since ASP.Net is running on the
Server. I can't think of any methods to get a client-side screenshot short
of using some java applet or active x...
