I do this in one of my utility programs (SaviColor). if you want to see what it does, download SaviColor from my utilities page.

Unfortunately, you will need to translate this from C#:

private int FH; private int FW; [System.Runtime.InteropServices.DllImport("gdi32", EntryPoint = "CreateDCA")] private static extern int CreateDC(string lpDriverName, string lpDeviceName, string lpOutput, string lpInitData); [System.Runtime.InteropServices.DllImport("GDI32")] private static extern int CreateCompatibleDC(int hDC); [System.Runtime.InteropServices.DllImport("GDI32")] private static extern int CreateCompatibleBitmap(int hDC, int nWidth, int nHeight); [System.Runtime.InteropServices.DllImport("gdi32", EntryPoint = "GetDeviceCaps")] private static extern int GetDeviceCaps(int hdc, int nIndex); [System.Runtime.InteropServices.DllImport("GDI32")] private static extern int SelectObject(int hDC, int hObject); [System.Runtime.InteropServices.DllImport("GDI32")] private static extern int BitBlt(int srchDC, int srcX, int srcY, int srcW, int srcH, int desthDC, int destX, int destY, int op); [System.Runtime.InteropServices.DllImport("GDI32")] private static extern int DeleteDC(int hDC); [System.Runtime.InteropServices.DllImport("GDI32")] private static extern int DeleteObject(int hObj);

protected void CaptureScreen() { int hSDC; int hMDC; int hBMP; int hBMPOld; int r; hSDC = CreateDC("DISPLAY", "", "", ""); hMDC = CreateCompatibleDC(hSDC); FW = GetDeviceCaps(hSDC, 8); FH = GetDeviceCaps(hSDC, 10); hBMP = CreateCompatibleBitmap(hSDC, FW, FH); hBMPOld = SelectObject(hMDC, hBMP); r = BitBlt(hMDC, 0, 0, FW, FH, hSDC, 0, 0, 13369376); hBMP = SelectObject(hMDC, hBMPOld); r = DeleteDC(hSDC); r = DeleteDC(hMDC); background = Image.FromHbitmap(new IntPtr(hBMP)); DeleteObject(hBMP); }

Does anyone know how to capture a screenshot of an AF frame into some type of graphics file (such as .gif) using code? I want to automatically keep a graphical record of how the user navigated through the application. I could manually capture the screen shots using windows "ctrl + Print Screen", but is there a way to do this using SCL code? Or maybe using call system?
