The first parameter is the file name, represented as a wide character (2-byte) Unicode™ string. For simplicity, the example program specifies a literal string, rather than have the user select a file name. The "L" prefix converts an ASCII string to a wide character string. 如:
CString a="sdfsdfsdfd";
......

CString a="sdfsdfsdfd";
......
然后要将其转换为wide character string,如何用"L"这个操作符??我用L(a)不行。
