Comments

Visual Basic and Delphi developers note that HWND is really an integer in 16 bit and a long integer in 32 bit. GetFocus and WinHelp are Windows API calls. Refer to your Visual Basic and Delphi documentation on calling Windows functions. These environments usually offer a different method of calling WinHelp so also search for WinHelp.
