没有定义UNICODE，所以它里面的字符串就是简单用" "就行了，创建工程的时候包含了UNICODE定义，就必须对TCHAR和char进行转换。

首先是把TCHAR转为char

1 void OpenFileName::TCHAR2Char(const TCHAR* tchar, char * _char)2 {3     int iLength;4 5     iLength = WideCharToMultiByte(CP_ACP, 0, tchar, -1, NULL, 0, NULL, NULL);6     WideCharToMultiByte(CP_ACP, 0, tchar, -1, _char, iLength, NULL, NULL);7 }

然后是把char转为TCHAR

1 void OpenFileName::Char2TCHAR(const char * _char, TCHAR * tchar)2 {3     int iLength;4 5     iLength = MultiByteToWideChar(CP_ACP, 0, _char, strlen(_char) + 1, NULL, 0);6     MultiByteToWideChar(CP_ACP, 0, _char, strlen(_char) + 1, tchar, iLength);7 }
