Hi,

I am trying to get Acrobat to draw a page into a System.Drawing.Image.HBitmap class, I have the following code which so far only grabs the desktop window, I need to get an HDC somehow but am not sure exactly where and how I should be doing it:

            _pdpage = (CAcroPDPage)_pddoc.AcquirePage(page);

            /// This line is the problem:
            IntPtr hDC = new IntPtr();

            AcroRect pdfRect = new AcroRect();

            pdfRect.Left = 0;
            pdfRect.right = 200;
            pdfRect.Top = 0;
            pdfRect.bottom = 200;
           
            _pdpage.DrawEx(0, hDC.ToInt32(), pdfRect, 0, 0, 100);

            IntPtr hMemDC = PlatformInvokeGDI32.CreateCompatibleDC(hDC);
            IntPtr hBitmap = PlatformInvokeGDI32.CreateCompatibleBitmap(hDC, pdfRect.right, pdfRect.bottom);

            IntPtr hOld = (IntPtr)PlatformInvokeGDI32.SelectObject(hMemDC, hBitmap);
            PlatformInvokeGDI32.BitBlt(hMemDC, 0, 0, pdfRect.right, pdfRect.bottom, hDC, 0, 0, PlatformInvokeGDI32.SRCCOPY);
            PlatformInvokeGDI32.SelectObject(hMemDC, hOld);
            PlatformInvokeGDI32.DeleteDC(hMemDC);
            Bitmap newBmp = System.Drawing.Image.FromHbitmap(hBitmap);
           
            PlatformInvokeGDI32.DeleteObject(hBitmap);
            GC.Collect();

            newBmp.Save("C:\\test.bmp");

Now all that code does is draw the desktop window to the file, I need to know where I'm going wrong.

Thanks in advance!
