Can CVI call interrupt 33h for display Pointer position in Windows XP?

[plit string]

I have to show the Pointer position on the XP screen without using LW or CVI 's GUI. Is there any way to do that or I have to use interrupt 33h? If in the latter case, how I do that in CVI codes to call interrupt 33h?

Thanks for any help

Int 33h is an MS-DOS interface and isn't applicable to Windows (not NT-derived Windows, anyway). If you need to avoid the CVI libraries (why?), the Windows API function you need is GetCursorPos(). More information here.

Actually, I only want to show the pointer on the Monitor without erasing any thing on it (as the mouse movement), but I do not know how to do it without using CVI GUI. Certainly, I have to provide the coordination (x,y) for it ... do you know how to do it

Sorry, it's not at all clear to me now what you want to do. Do you want to get the mouse pointer position, set the position, or do something else?

Really I would like to show a Pointer moving cross the Monitor screen without erasing any thing on it (the mouse doing the same thing), I will provide the coordination XY coordination. That was why I did not want to use any GUI from CVI.

Using the Windows API functions to draw on the screen isn't really a topic for this forum. It is straightforward but rather tedious. You should look at the GDI documentation on MSDN, in particular this section, for more information.

Thanks for the link. It is good enough for me
