Hi Experts,

I'm having a problem with the following piece of code.. Don't kno the reason for it and how to go bout correcting it...

---------------------------------

Dim Cmd1 As OleDb.OleDbCommand = New OleDb.OleDbCommand("SELECT UserName FROM Login WHERE UserName=" & txtUser.Text, Conn)

Dim userid As String = New String(CStr(Cmd1.ExecuteScalar))

since it is a character field, you need to put quotes around the value:

Dim Cmd1 As OleDb.OleDbCommand = New OleDb.OleDbCommand("SELECT UserName FROM Login WHERE UserName='" & txtUser.Text & "'", Conn)
