Weird Character Allocation Problem.
-
I have the following code: TCHAR * ptszVersionInfo = _T(""); //Executes OK ptszVersionInfo = new TCHAR[10]; //Executes OK delete ptszVersionInfo; //Executes OK ptszVersionInfo = _T("Anton"); //Executes OK delete ptszVersionInfo; //Weird erro. From debug assert.It basically says there is an error with _CrtIsValidHeapPointer. Now how come. (I am not very good with string allocation X| ).

HAHAHA_NEXT wrote: Is there a way i can allocate _T("Anton") Into a dynamic memory ? This does not quite make sense, but I think what you want is:
TCHAR *p = new TCHAR[6];
_tcscpy(p, _T("Anton"));
...
delete [] p;

Ths. It is exactly what i needed. The reason for this kind of weird stuff is because i can allocate the same string 2 ways: the first is
p = "Anton"and the second isp = new TCHAR[6]; _stprintf(p, ....)This will avoid me having different variable and one clean delete statement :). -
