reading the loginname

Hi,
I want to know that is this possible to read the user which has logged in on a windows machine from a VB6.0 application.For ex.there is a user named jeff who logs in ,I want my application to create a read only text file named jeff.txt mentioning the time when he logged in and logged out.The data should be appended to this file everytime jeff logs in and logs out.

manish

i know there is an api call to check the name of the person currently logged in. check allapi.net to get the username. once u have done that, what you can do is make the program invisible, put it up in startup items for all users, and in the form_unload you can add the logout time and save the login time and logout time.

VB Code:

Declare Function GetUserName Lib "advapi32.dll" Alias "GetUserNameA" (ByVal lpBuffer As String, nSize As Long) As Long

From API GUIDE

VB Code:

'This project needs a timer
Private Declare Function GetUserName Lib "advapi32.dll" Alias "GetUserNameA" (ByVal lpBuffer As String, nSize As Long) As Long
Private Declare Function GetTempPath Lib "kernel32" Alias "GetTempPathA" (ByVal nBufferLength As Long, ByVal lpBuffer As String) As Long
Private Declare Function IsIconic Lib "user32" (ByVal hwnd As Long) As Long
Private Sub Form_Load()
    'KPD-Team 1998
    'URL: [url]http://www.allapi.net/[/url]
    'E-Mail: [email][email protected][/email]
    Timer1.Interval = 100
    Timer1.Enabled = True
    Dim strTemp As String, strUserName As String
    'Create a buffer
    strTemp = String(100, Chr$(0))
    'Get the temporary path
    GetTempPath 100, strTemp
    'strip the rest of the buffer
    strTemp = Left$(strTemp, InStr(strTemp, Chr$(0)) - 1)
 
    'Create a buffer
    strUserName = String(100, Chr$(0))
    'Get the username
    GetUserName strUserName, 100
    'strip the rest of the buffer
    strUserName = Left$(strUserName, InStr(strUserName, Chr$(0)) - 1)
 
    'Show the temppath and the username
    MsgBox "Hello " + strUserName + Chr$(13) + "The temp. path is " + strTemp
End Sub
Private Sub Timer1_Timer()
    Dim Boo As Boolean
    'Check if this form is minimized
    Boo = IsIconic(Me.hwnd)
    'Update the form's caption
    Me.Caption = "Form minimized: " + Str$(Boo)
End Sub

HTH ;)

Once you have the username

VB Code:

Open "c:\loginfile.txt" For Append As #1
Print #1, username & " logged in at: " & Now
Close #1

Bare in mind that the GetUserName API acts differently if you are running Win2000 or XP.
