dparsons, you're very kind to try to keep helping airjaws, but I think he's not going to get it. He should read his vb.net book(s) and hang out in the beginner's forum for a while.

yes, he is very kind to try to help me, and you are too. yes, im beginner, but i dont have time to study whole book, this stuff has to be done by wednesday or im doomed :(

Sorry, you're doomed, then. There are many competent consultants your boss can hire to write this code. As always, good luck.

lol its not boss. its the project that ive got from my teacher at university altough ive never seen VB before for some odd reason he gave me assigment in it for signature. here in croatia when you listen class at university you get signatures from professor. i was that luck to get this project btw...

it should look like this or not?:
Dim check As ???
check = ????????("select [password] from [tablename] where [login] = 'txtLogin.Text'")
If check= txtPass.Text Then
frmMain.Show()
Else
MsgBox("access dinied")
End If

am i near solution? what to put instead of those questionmarks. if ive used access database i would put recordset, but what if i use sql database instead, as i said before?
is it so difficult to help?

My first post was not meant to be a cure all to solve your problem, it was meant to show you the logic behind doing something like this.

If that is the select statement you are using, you can do something like this: SELECT Count([password]) from table where login = '" & txtLogin.Text &"'"

And then use ExecuteScalar() to execute the query against your database and, by doing this, it will return you the value of Count. If that value is 0 you know that an invalid login was provided, else it was correct.

hth.

dparsons sorry for spamming the forum. FINALLY, i've reached solution. it was similar to my second post in this thread. so basically it looks like this:

        Dim counter As Integer
        Dim check As Boolean = False

        counter = Me.DataSet.table_name.Rows.Count

        For i As Integer = 0 To counter - 1

            If Me.DataSet.table_name.Rows(i).Item("login") = txtLogin.Text And Me.DataSet.table_name.Rows(i).Item("pass") = txtPass.Text Then
                check = True
                frmMain.Show()
                Exit For

            End If
        Next i

        If check = False Then MsgBox("Wrong login name or password! Access dinied!")

thanx everyone for trying to help.

Depending on your query you could just do

If counter = 0 Then
MsgBox("Wrong login name or password! Access dinied!")
Else
frmMain.Show()
End If

in any case glad you got it working.
