各位大虾，如何将GUID或CLSID结构转换成这种形式？

类似于这种的{C2ABC522-210E-4C79-92FF-50E03DD91D80}字符串，一定给分。

使用函数StringFromGUID2():

Converts a globally unique identifier (GUID) into a string of printable characters.

int StringFromGUID2(
REFGUID rguid, //GUID to be converted
LPOLESTR lpsz, //Pointer to resulting string
int cchMax //Size of array at lpsz
);
Parameters
rguid
[in] GUID to be converted.
lpsz
[out] Pointer to a caller-allocated string variable to contain the resulting string on return.
cchMax
[in] Number of characters available in the buffer indicated by lpsz.
Return Values
0 (zero)
Array at lpsz is too small to contain a string representation of a GUID.
Non-zero value
The number of characters in the returned string, including the null terminator.
Remarks
The string that the lpsz parameter receives has a format like that of the following sample:

{c200e360-38c5-11ce-ae62-08002b2b79ef}
where the successive fields break the GUID into the form DWORD-WORD-WORD-WORD-WORD.DWORD covering the 128-bit GUID. The string includes enclosing braces, which are an OLE convention.

Requirements
Windows NT/2000: Requires Windows NT 3.1 or later.
Windows 95/98: Requires Windows 95 or later.
Header: Declared in objbase.h.
Library: Use ole32.lib.

要注意
LPOLESTR lpsz
要大于40
好像是吧
