I realize this is not directly on topic and will keep it brief. I am attempting to use the WOW functions that come with vc++ 5.0 in order to enhance the capabilities of OI. These functions work fine to declare memory off the 16-bit global heap in windows 95/98, but are causing an access violation in NT. I know some people here have used the wow functions inside .dll's to expand the abilities of OI.. if anyone has been successful using WOWGlobalAlloc16 in NT, please help!,

[notag]Ken,
If memory serves, the type of thunking you are attempting (32→16 bit ?) will only work on Win95/98 systems, not on NT, although the 16→32 bit WOW functions work on both platforms.
One way around this problem I found was to use the WM_COPYDATA message to pass data between my 32 bit app and a 16-bit 'proxy' window which then passed the request onto the 16-bit DLL in the normal fashion.
