c# capture le contenu de la fenêtre sans frontières - Stack Overflow

I have to capture content and only content of one window. Like that:

(captured by ScreenCaptor)

But my program captures that:

I use this code:

IntPtr ParenthWnd = GetForegroundWindow();
        if (!ParenthWnd.Equals(IntPtr.Zero))
        {
            IntPtr prevChild = IntPtr.Zero;
            IntPtr currChild = IntPtr.Zero;
            while (true)
            {
                currChild = FindWindowEx(ParenthWnd, prevChild, null, null);
                if (currChild == IntPtr.Zero) break;
                result.Add(currChild);
                label3.Text += currChild.ToString() + " _ ";
                prevChild = currChild;
            }
        }

then I choose my child window, e.g:

handle = result[0];

and finally capture screenshot:

RECT rect = new RECT();
            GetWindowRect(handle, ref rect);

            Bitmap image = new Bitmap(rect.Right - rect.Left, rect.Bottom - rect.Top);

            using (Graphics graphics = Graphics.FromImage(image))
            {
                IntPtr hDC = graphics.GetHdc();
                PrintWindow(new HandleRef(graphics, handle), hDC, 0);
                graphics.ReleaseHdc(hDC);
            }

of course I cannot crop captured image, because don't know size of each 'border'

thanks in advance
