The GetUserName function retrieves the user name of the current thread. This is the name of the user currently logged onto the system.
BOOL GetUserName(
LPTSTR lpBuffer, // address of name buffer
LPDWORD nSize // address of size of name buffer
);
Parameters
lpBuffer
Pointer to the buffer to receive the null-terminated string containing the user's logon name. If this buffer is not large enough to contain the entire user name, the function fails. A buffer size of (UNLEN + 1) characters will hold the maximum length user name including the terminating null character. UNLEN is defined in LMCONS.H.
nSize
Pointer to a DWORD variable that, on input, specifies the maximum size, in characters, of the buffer specified by the lpBuffer parameter. If the function succeeds, the variable receives the number of characters copied to the buffer. If the buffer is not large enough, the function fails and the variable receives the required buffer size, in characters, including the terminating null character.
Return Values
If the function succeeds, the return value is nonzero, and the variable pointed to by nSize contains the number of characters copied to the buffer specified by lpBuffer, including the terminating null character.
If the function fails, the return value is zero. To get extended error information, callGetLastError.
Remarks
If the current thread is impersonating another client, the GetUserName function returns the user name of the client that the thread is impersonating.
QuickInfo
Windows NT: Requires version 3.1 or later.
Windows: Requires Windows 95 or later.
Windows CE: Unsupported.
Header: Declared in winbase.h.
Import Library: Use advapi32.lib.
Unicode: Implemented as Unicode and ANSI versions on Windows NT.

CDaoWorkspace::GetUserName?是CString类型的啊。
MFC中好像没有上面几位大虾说的BOOL GetUserName吧？

参数说明：
LPTSTR lpBuffer接收用户名，字符串
LPDWORD nSize 是个变量，要初始化，指定字符串的长度，返回后接受用户名实际长度
