WebOct 10, 2008 · CString has an inner cast Operator ( LPCTSTR) which converts the CString object to a const char* (if compiling ANSI) of const wchar_t* (if building unicode), so you should not have to do any much stuff. And please (if you get this advice from anywhere), don't use the CString::GetBuffer ()) method at all for such a thing !!! If you just want the value of the string for reading, use the casting operator like this: CString str ("hello"); printf ("%s\n", (LPCSTR)str); //The cast operator here gets a read-only value of the string. Now if I can convert this into CString, then I"ll use CString's GetBuffer () method to convert it into LPSTR.
