unload DLL
-
my problem: I have to port a Project from C++ to C# there is a DLL, i can load
[DllImport("blabla.dll")] public extern static void CancelSearch(); . . .and use it... and then end the programm BUT there is a deadlock, cause theFreeLibrary();is never called by C# :( (if I remove the FreeLibrary(); in C++ then the C++ App hangs too) any idea how to unload the DLL? -

regsvr32 -u blabla.dllYou should get a prompt saying it has been unregistered. HTH Nick Parker

Any dll (assembly) that gets loaded will be written to the debug console when they are loaded. MYrc : A .NET IRC client with C# Plugin Capabilities.

no, the DLL is not registered.. its just a normal DLL ... it waits till I call the
FreeLibrary();function .... but I have no idea how to do this in C#So are you only trying to call the
FreeLibrary();function from this .dll? If so and it is non .NET then you will need to use COM Interop. HTH Nick Parker

thanks! I think this may work.... but I can't find any sample code with AppDomains do you know a link?:-O

Normal DLL's dont use COM, and thus COM-interop will not be useful here.
