adding a c++ code in WD Mobile

Dear WD mobile coders,
does anyone here has an experience on adding the C++ commands inside WD Mobile?

for example, I am having a c++ file called "PrinterDemo.CPP" , how to use this file inside WD Mobile ?

for dotnet , it is very easy to import as dotnet assemblies, but for c++ i have zero idea :-(


help please

Hi Mitchell

You'll have to create a dll with the C code, then call the dll from wm

Best regards

HI Mitchell,
just to give you an idea how such a DLL could look like.

(you have to modify your PrinterDemo.CPP a little and export the C++ function like shown in this little sample)

// testdll.h

#ifdef TESTDLL_EXPORTS
#define WDEXPORT extern "C" __declspec(dllexport)
#else
#define WDEXPORT  extern "C" __declspec(dllimport)
#endif


WDEXPORT int fntestdll(void);
WDEXPORT void fninc(int* intptr);

and it's implemetation

// testdll.cpp : Defines the entry point for the DLL application.

#include "stdafx.h"
#include "testdll.h"


BOOL APIENTRY DllMain( HANDLE hModule, 
                       DWORD  ul_reason_for_call, 
                       LPVOID lpReserved
					 )
{
	switch (ul_reason_for_call)
	{
	case DLL_PROCESS_ATTACH:
	case DLL_THREAD_ATTACH:
	case DLL_THREAD_DETACH:
	case DLL_PROCESS_DETACH:
		break;
	}
    return TRUE;
}


// This is an example of an exported function.
WDEXPORT int fntestdll(void)
{
	return 42; // what else 
}
WDEXPORT void fninc(int* intptr)
{
	++*intptr;
}
