Declare Function ReleaseDC Lib "user32.dll" (ByVal hWnd As Long, ByVal hdc As Long) As Long

Example:
' Example for ReleaseDC
deskhwnd = GetDesktopWindow() ' API gets handle to desktop
deskhdc = GetDC(deskhwnd) ' gets desktop's device context
' put code that uses deskhdc here
x = RelaseDC(deskhwnd, deskhdc) ' free up resources
