Hi,
I also got the smae error some times in borland c++. In my case that dll
is not valid. Because i am working in borland c++ and the dll is created in
MS. After I Apply CoffToOMF utility on dll, it is working fine. I don't know
this is the problem with you. Any way i will go through that.
Thanks
Arun
