[shell-coding] Re: try() catch()

In regards to your question about object unwinding, you cannot use __try in functions that require object unwinding , with /GX  switch a function with structured exception handling cannot have objects that require unwinding (destruction). This is what I was refering to when you asked about the try statement , sorry for not explaining more when I responded , my mistake ;) .  I did a little research and what I found here: http://msdn.microsoft.com/library/default.asp?url=""> was very helpful.  What I would do for your try/catch statment :

Try

{

   ?

   throw IError;

}catch (IError e)

{

       TCHAR tzError[MAX_LINE_LENGTH];

       If (e.LoadString (IDS_MODULEINITEXCEPTION_ERROR, tzError,MAX_LINE_LENGTH)){

            StringCchPrintf(tzErrorEx, MAX_LINE_LENGTH, tzError, iter->first.c_str());

            e.MessageBox(NULL, tzErrorEx, IDS_LITESTEP_TITLE_ERROR);

       }

}

I hoped this helped some..
