Re: Dllimport method calling failed in web form

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hello Billy,

Sorry for my misunderstanding at the very beginning. I assumed that you
meant the DLL could not be called by ASP.NET when it was said "the method
doesn't work and returns false". I'm sorry, Billy, that I should have
clarified my understanding before giving the suggestions.

If the function returns true when run in a winform, but returns false
inside a ASP.NET page, it's likely to be "impersonation" issue. Does the
DLL function needs to run under a certain user account? If yes, the KB
article:

How to implement impersonation in an ASP.NET application
http://support.microsoft.com/kb/306158

may help you with it. It demonstrates several choices of impersonation with
easy-to-follow example codes. Please have a try and let me know whether it
works for you.
