API Explanation
The CreateCursor function creates a cursor having the specified size, bit patterns, and hot spot. Parameter Information Declare Function CreateCursor Lib "user32" Alias "CreateCursor" (ByVal hInstance As Long, ByVal nXhotspot As _ Long, ByVal nYhotspot As Long, ByVal nWidth As Long, ByVal nHeight As Long, lpANDbitPlane As Any, _ lpXORbitPlane As Any) As Long

Private Declare Function CreateCursor Lib "user32" (ByVal hInstance As Long, ByVal nXhotspot As Long, ByVal nYhotspot As Long, ByVal nWidth As Long, ByVal nHeight As Long, lpANDbitPlane As Any, lpXORbitPlane As Any) As Long
