Problems using c++ library from c#

[xmardaras]

Hello,

I have a missingmethodexception when I try to use it.
I use eVC++ 4.0 and PPC 2003.
I know that the dll is in the same folder that the application is
executed.
I get this exception, incluso even when I return nothin and with no
parameters in the function.
I have declared the function in one of my .cpp:

extern "C" void __declspec(dllexport) __cdecl Recog();

extern "C" void __declspec(dllexport) __cdecl Recog()
{
MessageBox(NULL,TEXT("Hello, I'm inside."),TEXT("Hello, I'm
inside."),MB_OK);
//Do something, The messagebox is not shown

}

In c# I use:

[DllImport("Reconocedor_DLL.dll")]
static extern void Recog();

I have tried with SetLastError, EntryPoint,... but nothing I have the
same exception.

Please help.

Best Regards.

If you run dumpbin.exe on the DLL, does it show the function is exported?
Have you compiled the DLL for the correct processor?

Thanks for your reply.

Yes, it apperas there in clean text, it's not decorated, and the
processor type is correct ARM.

I've tried with empty libraries that exposes a single function, and
this runs ok.
I think it could be a problem withSupposing):
- Dependencies of my library in runtime, but It compiles ok.
-With precompiled headers, I another project with automatic precompiled
headers, the same exception, but it can be derived from the firs error
type.

Thanks.

I've found the problem, my library has some dependencies to another
libraries, so my library has to be in the same folder of the other
libraries
