I try to create a unmanaged dll in C++ with visualt studio 2005 and the i want to use it in a c# project.
My first question is hoaw to create a C++ (unmanaged) dll project for smartphone in visual stuido 2005. I create a Win32 projecdt>>dll project but i supopose it's only for deskop.
After that i wrote my dll.
.CPP
#include
"MyDll.h"// This is an example of an exported function.
MYDLL_API int fnMyDll()
{return 42;}
.H
#ifdef
MYDLL_EXPORTS#define MYDLL_API __declspec(dllexport)
#else
#define MYDLL_API __declspec(dllimport)
#endif
MYDLL_API int fnMyDll();
Then i use it in my C# project
[DllImport("MyDll.dll",EntryPoint="fnMyDll",CharSet=CharSet.Unicode)]
private static extern int fnMyDll();
int GetInt()
{
return fnMyDll();
}
-----------------
But at run time i get a Missing Methode Exception.
For running my app i direclty dowload the dll in the exe folder, so the exe should find the methode :s
So does anyone knows how to make such a thing (creat a C++ dll project for smartphoen and then use it i a C# project) with visual 2005

So how can i create a simple C++ dll, for the moment i cretae my C++ dll in embedded VC ++ and upload the dll on my real smartphone. The tests are not possible since code for embedded VC++ emulator and Visual Stuidio 2005 emulator are not compatible.
So my question is still the same, how to create a basic C++ dll for smartphone from Visual Stuidio 2005
Thanks

..or you could use dumpbin to declare the name exactly as it is exported. More here:

Select the "Other Language/Visual C++/Smartdevice" and then template "Win32 Smart Device Project" in the New Project dialog. This presents a wizard that has a selection "Application Settings". It is there you can select "DLL" as the project type.
