Answer 1

Try changing your statement to read

If password.Text <> "" And username.Text <> "" Then 
   btnLogin_Click(Nothing, Nothing)
End If

Your current code is using the signature as if you were creating the button click event, you simply need to pass it some dummy arguments into the method, provided it has been written.

However, if you are triggering a login through various methods, I'd recommend writing a second method called ProcessLogin or something to that matter and have your button click event simply redirect to there. This will make it easier to have multiple "entry vectors" to your login processing.

You need to change line 28 from

If password.Text <> "" And username.Text <> "" Then btnLogin_Click(Dim sender as Object, Dim e as System.EventArgs)

to

If password.Text <> "" And username.Text <> "" Then btnLogin_Click(Nothing, EventArgs.Empty)
