Hi,
Do you want a simple login form validating the valid user from Ms access db.
here is sample code with vb.net.
Dim cn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\testdb1.mdb;Jet OLEDB:Database Password=1234;")
Dim cmd As OleDbCommand = New OleDbCommand("Select * from testtable where username= '" & TextBox1.Text & "' ", cn)
cn.Open()
rdr = cmd.ExecuteReader
If rdr.HasRows Then
Else
MsgBox("Incorrect Username/Password")
TextBox1.Clear()
TextBox1.Clear()
End If
