What's the point of your example ?? You throw something that is caught two lines under. Why do you need to throw an exception for such a thing ? That's just totally not adapted.

But now, how can you inform the users of your object that something went wrong during construction of the object ? Well, in general you throw an exception out of your constructor.

In the exception handler of constructor.

// CDummyClass might throw an exception if it fails to construct<br />
void MyFunc<br />
{<br />
   try<br />
   {<br />
      CDummyClass test();<br />
      test.DoSomething();<br />
   }<br />
   catch (....)<br />
   {<br />
      // Ok CDummyClass failed to construct so we'll try something else.<br />
   }<br />
}
