Alternative Managed API:

Do you know one? Please contribute it!

Notes:

Use GetWindowDC(IntPtr hWnd); for taking the dc for the whole window since this function only gets the client area of the window.

Tips & Tricks:

Use IntPtr.Zero for hWnd to get a dc for the whole screen(Thanks to Mr.Charles Petzold.).

Please add some!

Sample Code:

IntPtr dc = GetDC(hWnd);

MoveToEx(dc,10,23,IntPtr.Zero);

LineTo(100,300);
