Oops, Carlosdl is correct. I didn’t follow the logic. The way the IFs are set up the program flow doesn’t have a chance to get to the manager vaildation.

“Looks to me like your READ is only reading the first record.”

I don’t think it needs to read more than 1 record, since only one user will be being validated on each try.

I think part of the problem is here:

Else
If String.IsNullOrEmpty(Form1.TextBox1.Text) Xor String.IsNullOrEmpty(Form1.TextBox2.Text) Xor Form1.rdbclerk.Checked = False _
Xor Form1.rdbmgr.Checked Then
MsgBox(“emp Login unsuccessful,pls type the correct details and select the correct usertype”)
End If
End If

Because of this code, if rdbmgr is checked, an unsuccessful login message will be displayed, no matter what the user entered as username and password.

But, it seems that it should then continue to validate using the manager validation code, and display a login successful message if the provided credentials were correct.

Dissector, can you tell us what happens when you try to login as a manager ?

Looks to me like your READ is only reading the first record. When you compare the clerk’s login info against it, it is OK, but when you compare the manager’s login info against the first record from the database, it fails. I think you need a way to loop through the records of the password database.
