Public Function SetClassLongPtr(hWnd as IntPtr, <MarshalAs(UnmanagedType.I4)>nIndex as ClassLongFlags, newLong as Integer) as Integer
Public Declare Function SetClassLongPtr Lib "user32" Alias "SetClassLongPtrA" _ SetClassLongPtr is 64-bit safe, SetClassLong is not. Because SetClassLongPtr is not available on older 32-bit operating systems, a special wrapper function is required. The MSDN documentation specifies that SetClassLongPtr is supported on older 32-bit operating systems such as Windows 95. However, the Win32 API actually uses a macro to change SetClassLongPtr to SetClassLong on these older systems.
