C# - Step 9 Writing C++ Test Application to test C# ClassLibrary

Here is the C++ code to test the C# Class Library (COM Server).

#include <stdio.h>

#include <tchar.h>

#define _ATL_CSTRING_EXPLICIT_CONSTRUCTORS

#include <atlbase.h>

#include <atlstr.h>

#include <iostream>

#import "../SFTCSServer/bin/x86/debug/SFTCSServer.tlb"

using namespace SFTCSServer;

int _tmain(int argc, _TCHAR* argv[])

{

::CoInitialize(NULL);

IMathCtrl *pMathCtrl = NULL;

CComPtr<IMathCtrl> ptr;

HRESULT hResult = ptr.CoCreateInstance(_T("SFTCSServer.MathCtrl"));

if(FAILED(hResult))

{

printf("Unable to create COM Object: 0x%x\n" , (DWORD)hResult);

return 0;

}

std::cout << ptr->AddNumbers(10, 15) << "\n";

std::cout << ptr->AddNumbers(10, 25) << "\n";

std::cout << ptr->AddNumbers(10, 35) << "\n";

return 0;

}
