What do you mean "what it would be"? It would be a parameterized query if it were paramterized, that is what it would be....

I tried to follow your instructions and this is my code now.

[code]
Dim str As String
str = "SELECT * FROM Login WHERE username= @txtUsername.Text & password = @txtPassword.Text"
Dim cmd As OleDbCommand = New OleDbCommand(str, DBconnection)
dr = cmd.ExecuteReader
If dr.HasRows Then
MsgBox("successfull")
Else
MsgBox("sorry")
End If
[/code]

'dr' is a datareader declared in my module

i get an error associated with the line "dr = cmd.ExecuteReader"
the error is "No value given for one or more required parameters."

No, you haven't followed my instructions at all. Re-read the links.
