What API function you're trying to use? What the reason you're using RegFn instead of the VFP DECLARE - DLL Command?

>SET LIBRARY TO SYS(2004) + "FOXTOOLS.FLL" ADDITIVE
>Help = RegFn("Help", "LCIC", "I")
>#DEFINE HELP_KEY 0x0101
>wCmd = HELP_KEY
>cFilename = "mqhelp.hlp"
>dwData = "Add Menu Items at Run Time"
>CallFn(HELP, MainHWND(), cFilename, wCmd, dwData)
