When he said CString to char[] it looked apparent it's non-unicode.
No, because when you never heard about UNICODE (like me when I started) and if you are using the latest visual studio versions where UNICODE is enabled by default, then you are in trouble. When I didn't understand anything about all that stuff, I was still using char* everywhere (instead of TCHAR*) and was forcing casts between everything. I can tell you that my code was a big mess X|

Otherwise he'd have used TCHARs
TCHAR is the generic type, it is not specifically UNICODE. You should use TCHAR as often as possible... Anyway, my whole point was: do not use GetBuffer/ReleaseBuffer and explicit casts, unless you exactly know what you are doing :) .

Agreed. :). I feel lazy at times & use these crude ways but only when I'm sure nobody else handles the code.

"Very-Urgent" = "Please ignore my message". That's the meaning in forums. Anyway, a crude way:
char ch\[128\]; CString cs = "YourName"; strcpy(ch, (LPSTR)(LPCTSTR)cs);You can also use GetBuffer, ReleaseBuffer.

Why the unnecessary casts?

Valid question. Actually I typed my reply with a char* . char* ch = (LPSTR)(LPCTSTR)cs; But knew that's a bad example. So changed that to char[] & and put the example as copy-the-buffer but had left the LPSTR caste unremoved . LPSTR is not need actually in this case.

Neither cast is needed. Just use:
strcpy(ch, cs);

:doh: Yes we've been discussing that it returns a const char by default. The reason why I used LPCTSTR is that I couldn't cast it straight to char*. As CString doesn't support non-const version. I'm stupid I didn't think before typing. So we don't need all these caste craps when you are copying the buffer.
