Hi All,

           I have some basic doubts in technical wise.

           Environment: windows 2003 server, VC++ 6.0 (win 32 console + MFC
SUPPORT)

           I am developing multi threaded application (server). In each
thread, I am creating objects in stack memory. Each object takes 2500 bytes.
Is it correct way to creating objects in stack memory for multi threaded
application?

In which memory (Stack or Heap) I have to create objects to improve the
performance?

    I am using so many CString objects in this application. Will it give any
unexpected results in my application in any conditions like application
crash or performance hit?

    Try-Catch blocks will hit performance for multi threaded application. Is it
correct?

A multithreaded application can use stack or heap or some of each. The
stack gives much better performace than heap. Using many CStrings is
not a problem. CString performance will probably improve if you upgrade
to VC++ 2005.
