Dim strConnection As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=F:\TEST\VB.net TEST\WindowsApplication1\WindowsApplication1\SKB.MDB"

Dim Username As String
Dim Password As String
Dim con As OleDbConnection = New OleDbConnection(strConnection)

con.Open()
da = New OleDbDataAdapter("select Username AND Passowrd FROM UserAccount ORDER BY Username", con)


Textbox1.Text = da.Fill(dt)
TextBox2.Text = da.Fill(dt)


' Textbox1.Text = "Username"
'TextBox2.Text = "Password"

If Textbox1.Text = Username And TextBox2.Text = Password Then
Show(MDIParent1)
Else
MsgBox("Please Enter the appropriate Username and Password", MsgBoxStyle.OkOnly)

End If
con.Close()
I mentioned the Code above and getting an Error in "Textbox1.Text = da.Fill(dt)
TextBox2.Text = da.Fill(dt)

Please help me
