MORE INFORMATION

The following sample code shows how to use the interface IUniformResourceLocator to create a shortcut to a URL. It creates a URL shortcut file at "C:\Mssupport.url" that points to the URL "http://support.microsoft.com."

#include <windows.h>
#include <intshcut.h>

HRESULT CreateShortcutToURL(LPCSTR pszURL, LPCSTR pszLinkFile);

int main()
{
  CoInitialize(NULL);
  HRESULT hRes = CreateShortcutToURL("http://support.microsoft.com","c:\\mssupport.url");
  if (SUCCEEDED(hRes))
  {
    // do something...
  }
  CoUninitialize();
  return 0;
}

HRESULT CreateShortcutToURL(LPCSTR pszURL, LPCSTR pszLinkFile)
{
  HRESULT hRes;
   IUniformResourceLocator *pURL = NULL;

  // Create an IUniformResourceLocator object
  hRes = CoCreateInstance (CLSID_InternetShortcut, NULL, 
    CLSCTX_INPROC_SERVER, IID_IUniformResourceLocator, (LPVOID*) &pURL);
  if (SUCCEEDED(hRes))
  {
    IPersistFile *pPF = NULL;

    hRes = pURL->SetURL(pszURL, 0);

    if (SUCCEEDED(hRes))
    {
      WCHAR wsz [MAX_PATH];   // buffer for Unicode string

      // Ensure that the string consists of ANSI characters.
      MultiByteToWideChar (CP_ACP, 0, pszLinkFile, -1, wsz, MAX_PATH);

      hRes = pURL->QueryInterface (IID_IPersistFile, (void **)&pPF);
      if (SUCCEEDED(hRes))
      {   
        // Save the shortcut via the IPersistFile::Save member function.
        hRes = pPF->Save (wsz, TRUE);

        // Release the pointer to IPersistFile.
        pPF->Release ();
      }
    }
    // Release the pointer to IUniformResourceLocator
    pURL->Release ();
  }
  return hRes;
}
