Accessing the REI with Visual C++

Below is a small example of how you can access the REI (Rose Extensibility Interface) using Microsoft Visual C++. The example is using the DTC (Direct To COM) feature of VC++.

// REI with 'Direct To COM' example

#include "stdafx.h"

#import "K:\Rose2000\rationalrose.tlb" no_namespace named_guids

int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
CoInitialize(NULL);
{
IRoseApplicationPtr RoseApp;

RoseApp.CreateInstance(CLSID_RoseApplication);

_bstr_t url(L"http://www.rationalrose.com");
RoseApp->OpenURL(url);

}
CoUninitialize();
return 0;
}

This small application creates an instance of Rose and lets it open "The Unofficial Rose WebSite" in an internet browser.
