Example Code

1. Overview:
This VI programmatically changes windows wallpaper

2. Description: 

The example calls the SystemParametersInfoA function from Windows user32 API:

BOOL WINAPI SystemParametersInfo(
  __in     UINT uiAction,
  __in     UINT uiParam,
  __inout  PVOID pvParam,
  __in     UINT fWinIni
);

- SPI_SETDESKWALLPAPER Sets the desktop wallpaper
- The value of the pvParam parameter determines the new wallpaper. To specify a wallpaper bitmap, set pvParam to point to a NULL-terminated string containing the full path to the bitmap file. Setting pvParam to "" removes the wallpaper. Setting pvParam to SETWALLPAPER_DEFAULT or NULL everts to the default wallpaper.

- For more information, reference MSDN documentation for this function here SystemParametersInfo Function.
