P/Invoke.net[^] is a good source of information.

VB9 is the latest version of VB.NET. This article[^] provides further explanation.

INSERT INTO LOGIN_OUT
(Time_login, Emp_ID, Logindate)
VALUES (?, ?, ?)
i set time login emp id and logindate as primary key
UPDATE LOGIN_OUT
SET Time_logout = ?
WHERE ('Time_login' = ?) AND ('Emp_ID' = ?) AND ('Logindate' = ?)
it add same column in Time_login but not in time_logout

This is nasty code.
Just do the same as you did for login, to store the logout. Surely it's going to work the same ?

no choice..this the code i only can think...mean the update i change to insert..?because when i login then go form 2...once i close form 2..automatically insert to time_out .in form 2 code that i wrote is
frmLogin.LOGIN_OUTTableAdapter.UpdateLogin(Format(Date.Now, "HH:mm:ss"), frmLogin.LoginTime, frmLogin.strID, frmLogin.LoginDate)
should i do the same thing with insert..?

I mean, you've written the code to store a date into the DB, so why not write the same sort of code here ? I know from watching the questions you ask that you've not understood my answers or done what I suggested, so I have no idea how you got the other one working, but it means you know how to insert a date, right ? I mean, if someone gave you code that works, you took the time to understand it, right ?
It doesn't matter if you're being paid for this code, or if you're a student ( except that if you're being paid, that is plain disgusting ), you should be taking the answers you get, and coming to an understanding of how they work, so you can become competent in your own right, instead of spending your life on these forums asking the same basic questions over and over.

no..no..i know i'm asking nasty question..i stil student...code i wrote myself...not copying from others...sometimes easy things i go think hard way to do...okok..i do the same thing as do my login

OK - a lot of people ask these sort of questions for their work. If you're a student, then that's cool. You just plainly are not yet at a commerical level and a lot of people seem to get jobs anyhow 
By all means, if you try to use the method you're using to insert the date on the login end, and you have a specific problem, feel free to post it here, but you should look at that code first, you should be able to reuse the date insert portion to insert a date again.

but one problem i do the logout in formclosing...how do i do the query?
Private Sub frmMenu_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
frmLogin.LOGIN_OUTTableAdapter.UpdateLogin(Format(Date.Now, "HH:mm:ss"), frmLogin.LoginTime, frmLogin.strID, frmLogin.LoginDate)
End Sub
why when i close the form it store in login time..but not logout column...
UPDATE LOGIN_OUT
SET Time_logout = ?
WHERE ('Time_login' = ?) AND ('Emp_ID' = ?) AND ('Logindate' = ?)

Well, for starters, are you sure the logindate and time of login you're passing in are correct ? I'd be inclined to suggest you can simplify this to where Emp_ID = ? and time_logout is null, or something to use the most recent login date. Also, the column names should not be in quotes.

Glad to help. For the record, your questions are not nasty. We have a lot of people asking these sort of questions when they are working, and THAT is nasty. Perhaps try saying in future that you're a student in your posts, I think you are getting stuck in the fallout from a negative feeling towards people who have taken jobs they are not ready for. If you're a student, any question is valid, and that's what we're here for.

I don't see any database code, but if the problem is getting the main form in sync with what happens in a child form, use delegates to call methods on your main form when things happen on the child form.

when i put .addnew, .update function to make sure my database is updated when the new info is added
' Put data in the array
'this is the first coding before database coding is added
gstrTo_Do_Array(intPriority, intCounter, 1) = txtTo_Do_Description
gstrTo_Do_Array(intPriority, intCounter, 2) = "Active"
gdtmTo_Do_Dates(intPriority, intCounter, 1) = Date
gdtmTo_Do_Dates(intPriority, intCounter, 2) = txtDue_Date
'this is the new coding with the database code
'but it doesnt work
gstrTo_Do_Array(intPriority, intCounter, 1) = txtTo_Do_Description
datTo_Do.Recordset.Addnew
datTo_Do.Recordset.Field("Comment")=txtTo_Do_Description
datTo_Do.Recordset.Update

You called AddNew, but then completely ignored the record object returned from it. You're not making any changes to the new record at all, you've just added a blank record to the dataset.

How you do this depends on the design of the application.
Either, your application should be tracking all of it's open forms, probably in a collection, so that it can close them all when needed, or if there is a chain of forms open, the user should be forced to close or cancel all open forms in order to get back to the main form.
Putting the logout option deep inside your app is not a correct design choice.

hai friends
i have a problem in access Ms-access database table..
for the database , i set a password...
and i written the following code to access it ....
Try
Dim con As New OleDbConnection("Provider=Microsoft.JET.OleDb.4.0;User Id=administrator;Password=xyz;Data Source=D:/DataBase/Master.mdb")
Dim da As New OleDbDataAdapter("select * from login", con)
Dim ds As New DataSet
da.Fill(ds, "login")
DataGridView1.DataSource = ds
Catch ex As Exception
MessageBox.Show(ex.Message, "database")
End Try
but it is giving the error like ...
Cannot start your application. The workgroup information file is missing or opened exclusively by another user.
then i closed all the files , even i restarted the system ....
but it is giving the error...
wt would be the problem ....
either in setting the password for the database
or in vb.net ( in the above code )
plz help me....
thanks in advance

try this code
I think this will work
' your connection string will be
Provider=Microsoft.Jet.OLEDB.4.0;Data Source = D:/DataBase/Master.mdb ; Persist Security Info=True ;Jet OLEDB:Database Password=xyz" 
|
|

Reverse the slashes in your connection string. Forward slashes are for command line parameters. Backslashes (\) are for file path names.
Your Access database has either has a database password or workgroup security setup on it. You can find the connection string format for this at http://www.connectionstrings.com[^]. You're using OLEDB (.NET). Do not use the ODBC versions!
If you have workgroup security, you have to specify the databases .MDW file in the string along with the database filename.
