Like dllimport in Microsoft Visual C ++

Question

I have a DLL, and I would like to use some of its functions.

#include <iostream>

using namespace std;

extern "C" __declspec(dllimport) int Initialize(char* localPort, char* adminServerName, int rpcTimeout);


int main()
{
    int res = Initialize("7864", "6000@kabc", 10000);

    return 0;
}

I don't have a .lib dll, so I can still link it. One thing that comes to my mind is to use the LoadLibrary function and then use GetProcAddress (). Is there another way?

When I compile the following code

• error LNK2019: unresolved external symbol _imp_Initialize refers to the _main function

• fatal error LNK1120: 1 unresolved external

I get the above errors

I am using Windows and Visual Studio 2008
