There are properties on the Pane class in VI Server that you can use to get/set the wallpaper. They are Background Image, and Background Mode.

E.g.

-Akash

Hi Akash,

Thanks for your answers, Maybe I havn't given the details, my wallpaper isn't LV front panel background image, but it is computer's destop wallpaper.

and your thread is supported at LV8.2, mine is LV7.1 (I can't find your thread at LV7.1 and LV8.0) .

this VI calls the SystemParametersInfo function from user32.dll.

The wallpaper (eventually) has to be a BMP. When you are manually setting a JPEG, for example, as your wallpaper, Windows actually makes a copy of this to a BMP format and uses that for the wallpaper. Check out the 'Wallpaper' and 'ConvertedWallpaper' regisrty entries under HKEY_CURRENT_USER\Control Panel\Desktop.

Could be a policy setting disallowing the change of the desktop background. Window policy editor does allow a myriad of settings being changed, that control such things as this.
