NetWkstaUserGetInfo

hello all: when i use NetWkstaUserGetInfo function

typedef struct \_WKSTA\_USER\_INFO\_1 {
	LPWSTR    wkui1\_username;
	LPWSTR    wkui1\_logon\_domain;
	LPWSTR    wkui1\_oth\_domains;
	LPWSTR    wkui1\_logon\_server;
}WKSTA\_USER\_INFO\_1, \*PWKSTA\_USER\_INFO\_1, \*LPWKSTA\_USER\_INFO\_1;

\_WKSTA\_USER\_INFO\_1 t;
char tm\[100\]={0};
NetWkstaUserGetInfo(NULL,1,(LPBYTE\*)(&t));
strcpy(tm,(char\*)t.wkui1\_username);

"65168" is the t.wkui1_username value why is not the current user name?

Since Unicode is defined, why not use:

TCHAR tm[100] = {0};
NetWkstaUserGetInfo(NULL, 1, (LPBYTE *) (&t));
_tcscpy_s(tm, _countof(tm), t->wkui1_username);

Because t should be a pointer instead:

LPWKSTA_USER_INFO_1 t;

I can't understand what do you mean? a struct or a point to a struct ,any difference?

Just take a look at the below piece of code and hope you will be clear.. DWORD dwLevel = 1; // Specifies the information level of the data LPWKSTA_USER_INFO_1 pBuf = NULL; NetWkstaUserGetInfo(NULL, dwLevel, (LPBYTE *)&pBuf); The 3rd parameter is the pointer to the buffer that holds the data. A point to note here is that this function will work only locally and will fail if you try to enumerate the list of remote users... Regards, Rane

I gave you the code. What's not to understand?

Yes, a big one. Notice the third argument to NetWkstaUserGetInfo() is supposed to be a BYTE**. The second pointer is there so that NetWkstaUserGetInfo() can allocate memory for the structure. Don't forget to call NetApiBufferFree().
