Nope...I wrote a 'HoT Corners' program.  I want to add the feature of disabling the screen saver when the mouse is in a 'hot corner'

Declare Function SystemParametersInfo Lib "user32" Alias "SystemParametersInfoA" (ByVal uAction As Long, ByVal uParam As Long, ByVal lpvParam As Any, ByVal fuWinIni As Long) As Long
Public Const SPI_SETSCREENSAVEACTIVE = 17
Public Const SPIF_SENDWININICHANGE = &H2

Disable:

  SystemParametersInfo  SPI_SETSCREENSAVEACTIVE, 0, 0, SPIF_SENDWININICHANGE
                       
Enable:

  SystemParametersInfo  SPI_SETSCREENSAVEACTIVE, 1, 0, SPIF_SENDWININICHANGE

If you have trouble with the above declaration (directly from API reference) you can try this one instead:

Declare Function SystemParametersInfo Lib "user32" Alias "SystemParametersInfoA" (ByVal uAction As Long, ByVal uParam As Long, ByVal lpvParam As Long, ByVal fuWinIni As Long) As Long
