VS2010 MFC CString Initialisation

Question

0.00/5 (No votes)

See more:

In my VS2010 MFC app (which was fairly recently convert from VS6) I have a piece of dialog code where I'm trying to initialize a CString to blank.

I've got:

C++

CString strX = _T("");
strX.Empty();

But after both operations, the debugger shows that the strX variable contains the string "standard".

It's driving me mad!

Can anyone suggest where it is coming from and how to get my VS2010 CString to work like my old VS6 CString?

Find out where the string "standard" is used，and check whether the sscanf() function is used. If so, maybe that is the problem. CString is a type for MFC, however sscanf() is a method of C.Do not use CString with sscanf(), just replace CString with char *. Hope it helps you.

OK - so far it appears that some third party code is overwriting the CNilStringData member of the default ATL string manager, changing the defition of a NULL string...
