HI Ed Rauh,
Thanks For Reply.
But Here the DLL Was written in c++ or vc++ Lower Versions.
The third party(DLL Generator) was given the interface related to our functions only .
Already they had 16-bit and 32-bit versions of the DLL.
but existing users and some applications are using the 16-bit DLL.So he didn't given the 32-bit DLL Interface to Us.
So We have to Use The 16-bit Version of DLL Only.
which platforms are better to acheive this and which way of approach is better.

Note1:We have to use the 16-bit code in 32-bit applications.
Note2:we don't have the source code.

we came to know that .. thunking is no more to help us for this above purpose.

any sort of help will be highly appreciable..
Than q.
