I want to make the hostname part of this string to be variable.. Currently, it is only fix to this URL:

_T(" --url=http://www.myurl.com/ --out=c:\\current.png");

I want to make something like this, so the URL is changeable..

_T(" --url=http://www." + myurl +  "/ --out=c:\\current.png");

update. Below is my latest attempt:

      CString one   = _T(" --url=http://www.");
      CString two(url->bstrVal);
      CString three = _T("/ --out=c:\\current.png");
      CString full = one + two + three;

      ShellExecute(0,                           
               _T("open"),        // Operation to perform
               _T("c:\\IECapt"),  // Application name
               _T(full),// Additional parameters
               0,                           // Default directory
               SW_HIDE);

The error is : Error 1 error C2065: 'Lfull' : undeclared identifier c:\test.cpp
