How to Call SetCursorPos() API to Move Mouse Pointer in FoxPro

• Microsoft Visual FoxPro for Windows, version 3.0
• Microsoft FoxPro for Windows, version 2.6a

SUMMARY

You can reposition the mouse pointer (cursor) by using the Windows API function SetCursorPos(). This function is documented on page 833 of the Windows SDK Programmer's Reference, Volume 2: Functions manual.

MORE INFORMATION

The SetCursorPos() function sets the position, in screen coordinates, of the mouse pointer. Here's the function syntax:

   void SetCursorPos(x,y)

Below are code examples for Visual FoxPro using the DECLARE command, and FoxPro 2.x using FOXTOOLS.FLL, that demonstrate how to move the mouse pointer to position 20,20.

NOTE: For backward compatibility, Visual FoxPro still supports FOXTOOLS.FLL (included in earlier FoxPro versions), the Visual FoxPro API library that allows calls to 16-bit .DLL functions. However, in Visual FoxPro, the DECLARE command is the preferred method for calling .DLL functions.

Visual FoxPro Example Using DECLARE

   DECLARE integer SetCursorPos in WIN32API integer, integer
   =SetCursorPos(20,20)
   CLEAR DLLS

FoxPro 2.x Example Using FOXTOOLS.FLL

   * Set library to FoxTools.FLL so we can call the Windows
   * API function.
   SET LIBRARY TO SYS(2004)+"foxtools.fll"

   * Register the SetCursorPos with having two integer inputs
   * and void return value.
   setcurpos=REGFN("SetCursorPos","II","")

   * Call the function and move the mouse to position 20,20.
   callsetc=CALLFN(setcurpos,20,20)

   * Release the FoxTools.FLL library.
