Question

I just created a Database Application for Requesting Parts.

It has several forms, one for the requester, one for the Supervisor Approval, one for the Purchase approval and one for the Clerk to use to know what to order.

Now I am a big fan of paperless, but my employer Really like their paper. Is there an easy way to WYSIWYG duplicate my Windows forms to paper?

I should also add that I am restricted to using the 2.0 .Net framework

Thanks

Here’s a code sample from MSDN that will do what you want:

[System.Runtime.InteropServices.DllImport('gdi32.dll')] public static extern long BitBlt (IntPtr hdcDest, int nXDest, int nYDest, int nWidth, int nHeight, IntPtr hdcSrc, int nXSrc, int nYSrc, int dwRop); private Bitmap memoryImage; private void CaptureScreen() {    Graphics mygraphics = this.CreateGraphics();    Size s = this.Size;    memoryImage = new Bitmap(s.Width, s.Height, mygraphics);    Graphics memoryGraphics = Graphics.FromImage(memoryImage);    IntPtr dc1 = mygraphics.GetHdc();    IntPtr dc2 = memoryGraphics.GetHdc();    BitBlt(dc2, 0, 0, this.ClientRectangle.Width, this.ClientRectangle.Height, dc1, 0, 0, 13369376);    mygraphics.ReleaseHdc(dc1);    memoryGraphics.ReleaseHdc(dc2); } private void printDocument1_PrintPage(System.Object sender, System.Drawing.Printing.PrintPageEventArgs e) {    e.Graphics.DrawImage(memoryImage, 0, 0); } private void printButton_Click(System.Object sender, System.EventArgs e) {    CaptureScreen();    printDocument1.Print(); } 

There are some caveats – there’s no exception checking here, plus you’ll need to be running in full trust in order to use the unmanaged BitBlt API – but this is probably the easiest way to print a Windows Forms form, as long as it is displayed on the screen.
