Need help with compiling warnings that might cause memory error

Hi I'm using vs2005.  I am getting a bunch of compiler warnings after I made
some changes to my code that was compiling clean.  I'm also getting memory
errors when I run my program and it's pinvoking some C++ code, which was
working also fine before.  I wonder if these warning are causing the problem.
 I would appreciate some help or suggestions on how to correct these.  Thanks.

Did you mix C# code with managed/unmanaged C++ code?

>>>> Main.cs

the .cs extension is reserved for C# code ???


Unfortunately I don't know of C# and little of managed C++. But AFAIK you should try to use pure managed code if you don't want to dive into a swamp called 'marshalling'.

Yes Alex, I am pinvoking dll that are written in C++.  I also pinvok dll written in C.  All these dlls can not be written in C# so I can only try to deal with it.  thank you.

Yes, but I think they can't be written in managed C++ as well. You have to write them in unmanaged C++ or in C and call them from managed C++ or C# by means of the marshaler.
