Dynamically load a shared lib created using gcc/Cygwin

["Yu-Cheng Chou" <cycchou at ucdavis dot edu>]

Hi,
I made a mistake in the previous reply.
Here I state my question again.

mylib.dll was built using gcc/cygwin based on some library that 
might depends on cygwin1.dll.
I don't want to load cygwin1.dll explicitly, but I do need to load 
mylib.dll dynamically at run-time in an application which was built by 
Visual C++ or .NET.

How should I do?

Thanks
