Not supplying the password
I am not supplying the password. I have used the following entries in the setup.ini file while installing the MSDE
[Options]
INSTANCENAME=TEST
SECURITYMODE=SQL
BLANKSAPWD=1

I think i no need a password here. I have also tried with password it is giving same problem. here the code...
Dim cnfordesktop As New System.Data.SqlClient.SqlConnection

'-----------------------
' Open the desktop connection
'-----------------------
Public Function OpenConnectionForDeskTop() As Boolean
Dim cnstr As String = ConnectionStringForDeskTop()
Try
cnfordesktop = New system.Data.SqlClient.SqlConnection(cnstr)
cnfordesktop.Open()
Catch e As SqlClient.SqlException
MessageBox.Show("Error Number: " & e.Number & ", Error Message: " & e.Message & ", Command: " & cnstr, "Database ", MessageBoxButtons.OK, MessageBoxIcon.Hand, MessageBoxDefaultButton.Button1)
Return False
End Try
Return True
End Function
'-----------------------

Public Sub CloseConnectionForDesktopVM()
Try

Catch ex As Exception

End Try
