I have a folder with a number of DLLs in it, some of them contain a specific routine (let's call it connect()), and some do not. Those which do contain that routine are considered as plugin DLLs. I want to use GetOpenFileName() to acquire a plugin DLL name to work with.
It is necessary not only to filter out all files that do not match the *.dll pattern, but also to check all of them for the presence of the connect() function.
Is it possible to achieve that with GetOpenFileName()? As I can see, it's possible to provide a hook procedure for it, however it is not clear whether this hook is suitable for file filtering.
