loading the classes in a native dll

  There's no such thing as a static native DLL. You can either have a static lib or a DLL. If you have a DLL, you can use LoadLibrary and GetProcAddress to dynamically load and invoke exported functions. You cannot dynamically load a static lib - it's not intended to be used that way.

  /clr is not compatible with static libs. So you cannot create a managed static lib (as of VC++ 8). And you cannot reflect over native types, so what you would like to do is not possible.

  ok, so as i understood, i compile my code as static dll, and use the loadlibrary and getprocaddress to get the functions and so on.
  
  hm, ok thx for the help :D

I am trying to load a Native Library developed in VC++ 6.0 using LoadLibrary() API. I need to get the Handle from the LoadLibrary API.When I call this LoadLibrary() API, I am gettin an exception "Can not return Marshal value". I want to pass this Handle as the second argument(ie.lpSource) in the FormatMessage(). Here i have shown the way i have done the defenition to load Native Message Defenition Library in managed C++. [DllImport("Kernel32.dll" )] extern "C" IntPtr* LoadLibrary( String* IN_csLibName); In my code, exception occurs when I try to execute the below LoadLibrary() API. IntPtr* pHandle; pHandle = LoadLibrary(csLibPath); Note: Here csLibPath holds the correct path . In VC++ 6.0 it works fine, but in .Net I am facing the above mentioned problem. Please help me to find out a solution for my issue.

  What do you mean by static DLL You mean a static lib, don't you

  Or if you actually mean a managed DLL written using C++/CLI, yes, you can use reflection on it (same as in C#).

  hey guys, i have a static linked native c++ dll i built. i want to try and load the c++ classes in it, from an exe (for example). i want to be able to load these classes, and make objects and start using them. im trying to implement a plugin system of some sort. is that feasible i have done it using C# and the System.Reflection, but what about native C++ Since its done in the .NET framework, then its done C++, cause what im imagining the .NET was built on C++, so its there somewhere, maybe somebody could help me out please. how r plugin systems implemented then note: i know the idea of making interfaces, and the classes in the dll have to implement that interface, so i can call them easily,but how to load the dll dynamicly at run time and make object form it. thx alot guys.
