Hi
I worked with ATL and i believe it has advantages over MFC when creating controls , COMponents..
Q1 :
what about WTL as an alternative for MFC for dialog based apps ?
the only advantage I know is it's available for download from MS site.. But no support..WTL 7.1
Q2 :
Supposed I have a good knowledge of ATL..Is it easy to switch to WTL from MFC ?
Have you seen this article on WTL?
The advantage of WTL over MFC is that it's much leaner and everything you can do in MFC you can ,with a little more raw api knowledge , do just as easy in WTL. ATL + WTL eliminates the need for MFC. It's easy to switch to WTL from MFC if you just remember that all those MFC calls use almost identical API calls, and use those instead. And besides that a lot of the ATL class definitions are exact copies of the MFC classdefinitions so you can just follow the MFC MSDN on those.
There's a few good walkthroughs on the codeproject site.
Seems that WTL gives better performance that MFC and a smaller EXE..
but it basicly replaces Window classes...
I'll have to make my set of classes to encapsulate the APIs :)
