I have this error when I run this code:

Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim ConnString As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\Passwords.accdb"

Dim SqlString As String = "Update [Pass] Set UserName = ?, Password = ?"

Using conn As New OleDb.OleDbConnection(ConnString)

Using cmd As New OleDb.OleDbCommand(SqlString, conn)

cmd.CommandType = CommandType.Text

cmd.Parameters.AddWithValue("UserName", TextBox1.Text)

cmd.Parameters.AddWithValue("Password", TextBox2.Text)



End Using

End Using
End Sub
End Class

I am a newbbie in xthis field so I will provide you details of the access database:

Database name: Passwords.accdb
Table name: Pass : Table
Fields in the table name: UserName and Password
I also uploaded a printscreen with my form

Any suggestions are very welcomed......
Thank you!

You didn't given the error which thrown during execution.

Try this, instead of using parameters, supply the values directly in the query and execute.
Like this
Dim SqlString As String = "Update [Pass] Set UserName = '"+TextBox1.Text+"', Password = '" + TextBox2.Text + '"

Make sure that the both text boxes are not null.
