Nice to hear somebody using VB.NET want to create DLL using cygwin/gcc
I dont think he will get answer for this Question from a VB.NET forum
They will advice to use only MS products.
May be a gcc forum will be able to help him.
Or a MinGW forum, see http://www.mingw.org/index.shtml
To solve ur issue U can also ask,
How to create COM/DCOM objects using gcc?
You may also look at Harold's site
There is some thing like this with VC and VB
Finaly if you are able to do it with cygwin, please let us know.
We can add it as another use of cygwin
