noprop at all u can do :
F.I.
//Testdll.h the Header file
#ifdef TESTDLL_EXPORTS
#define WDEXPORT extern "C" __declspec(dllexport)
#else
#define WDEXPORT extern "C" __declspec(dllimport)
#endif
// define your exported functions
WDEXPORT int fntestdll(void);
WDEXPORT void fninc(int* intptr);
// Testdll.cpp
#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 exported functions.
WDEXPORT int fntestdll(void)
{
return 42; // what else
}
WDEXPORT void fninc(int* intptr)
{
++*intptr;
}
//WINDEV
res is int = API("TestDLL", "fntestdll")
//or
res is int = 100
API("TestDLL", "fninc", &res)
Trace(res) // 101
3 hints :
add WDEXPORT to the function you wanna access from WD.
pass structures as references use : &,
be very carefule in case that you find char* !!!
