Avoid C style declarations, use

struct MYSTRUCT {};

Often all caps names are reserved for macros.

i am a allocating memory as
MYSTRUCT *Mystr = new (MYSTRUCT );

You don't have to add the parenthesis here.

?but how to free this memeory ???/////

delete Mystr;

After what? Please quote the context you are replying to.

What sort of exception? Please post some code that reproduces the problem.

Hello,

I assume that you used TCHAR*c;
If yes, you'll need to free it first before delete the whole struct.

Cheers,

Note that your suggestion refers to how to avoid a memory leak of the data
pointed to by that pointer (which would best be handled by a destructor, by
the way). The original poster said there's an exception, which would be
caused by something other than forgetting to call delete on that member.
(But as there's no code shown where the class is used, it's impossible to
know what causes the exception at this point.)
