char* CStringToCharArray(CString str){char *ptr;#ifdef _UNICODELONG len;len = WideCharToMultiByte(CP_ACP, 0, str, -1, NULL, 0, NULL, NULL);ptr = new char [len+1];memset(ptr,0,len + 1);WideCharToMultiByte(CP_ACP, 0, str, -1, ptr, len + 1, NULL, NULL);#elseptr = new char [str.GetAllocLength()+1];sprintf(ptr,_T("%s"),str);#endifreturn ptr;}
