Original Post
I've tried to run this bit of code and it doesn't work, I had added the directory where my dll was, but it still doesn't recognises it. What am I doing wrong? What am I doing wrong with my dll linking in visual studio 2010 (full edition).
//This is windows
#define WINDOWS
#include <iostream>
#ifdef WINDOWS
#include <windows.h>
#endif
//Dynamic link libraries
#ifdef WINDOWS
typedef int (__cdecl *MYPROC)(LPWSTR);
#endif
int main( void )
{
//Dynamic link libraries
#ifdef WINDOWS
HINSTANCE hinstLib;
MYPROC ProcAdd;
BOOL fFreeResult, fRunTimeLinkSuccess = FALSE;
// Get a handle to the DLL module.
hinstLib = LoadLibrary(TEXT("BlessfuncDLL.dll"));
// If the handle is valid, try to get the function address.
if (hinstLib != NULL)
{
ProcAdd = (MYPROC) GetProcAddress(hinstLib, "BlessfuncDLL");
// If the function address is valid, call the function.
if (NULL != ProcAdd)
{
fRunTimeLinkSuccess = TRUE;
(ProcAdd) (L"Message sent to the DLL function\n");
}
}
//////////////////////////////////////////////////////////////////////
//Using code from DLL
using namespace std;
double a = 7.4;
int b = 99;
cout << "a + b = " <<
MathFuncs::MyMathFuncs::Add(a, b) << endl;
cout << "a - b = " <<
MathFuncs::MyMathFuncs::Subtract(a, b) << endl;
cout << "a * b = " <<
MathFuncs::MyMathFuncs::Multiply(a, b) << endl;
cout << "a / b = " <<
MathFuncs::MyMathFuncs::Divide(a, b) << endl;
//////////////////////////////////////////////////////////////////////
// Free the DLL module.
fFreeResult = FreeLibrary(hinstLib);
// If unable to call the DLL function, use an alternative.
if (! fRunTimeLinkSuccess)
printf("Message printed from executable\n");
#endif
while(1){}
return 0;
