>I have an app that runs in winxp desktops and also terminal server. If running on terminal server it needs to "declare integer WTSQuerySessionInformation in Wtsapi32.dll". If the app is running on xp it needs to skip this as it won't exist. What is a good way to determine how to load this dll or not?

Joe,

You can use following code

DECLARE long LoadLibrary IN WIN32API String
DECLARE Long FreeLibrary IN WIN32API Long

lcDllName = "Wtsapi32.dll"

lnLibHandle = LoadLibrary(lcDllName)

IF lnLibHandle  <> 0
	*? "TS"
	DECLARE Long WTSQuerySessionInformation in Wtsapi32.dll	
	= FreeLibrary(lnLibHandle)
	*...
ELSE
	*? 'Not TS"	
ENDIF	

BTW, I'm running WinXP SP3 and Wtsapi32.dll is present on my system.
