Has anyone managed to copy and paste the contents of WinForm as MetaFile? I
can copy and paste a 'screen dump' of the Winform. My WinForm has several
ActiveX controls on it - so just Calling OnPaint() with my own Graphics
does not work.
The code to copy and paste a 'screen dump':
[System.Runtime.InteropServices.DllImportAttribute("gdi32.dll")]
private static extern bool BitBlt(
IntPtr hdcDest, // handle to destination DC
int nXDest, // x-coord of destination upper-left corner
int nYDest, // y-coord of destination upper-left corner
int nWidth, // width of destination rectangle
int nHeight, // height of destination rectangle
IntPtr hdcSrc, // handle to source DC
int nXSrc, // x-coordinate of source upper-left corner
int nYSrc, // y-coordinate of source upper-left corner
System.Int32 dwRop // raster operation code
);
private void button4_Click(object sender, System.EventArgs e)
{
Graphics g1 = this.CreateGraphics();
Image MyImage = new Bitmap
(this.ClientRectangle.Width,this.ClientRectangle.Height, g1);
Graphics g2 = Graphics.FromImage(MyImage);
IntPtr dc1 = g1.GetHdc();
IntPtr dc2 = g2.GetHdc();
BitBlt(dc2, 0, 0, this.ClientRectangle.Width, this.ClientRectangle.Height,
dc1, 0, 0, 13369376);
g1.ReleaseHdc(dc1);
g2.ReleaseHdc(dc2);
Clipboard.SetDataObject(MyImage);
}
