Public Declare Function GetDC Lib "user32.dll" _

User-Defined Types:

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.).
An IntPtr is a pointer to a memory location (unmanaged) that adapts to the platform it is running on (64-bit, etc.) UNLIKE a standard int/Integer. You should always use this type for unmanaged calls that require it, even though an int will appear to work on your development machine.
