how to add namespace to vbnet page

I am trying to get screen width with something like   Width = Screen.PrimaryScreen.Bounds.Width.
I understand I need to add the System.Windows.Forms namespace.  I have tried to add the namespace reference but says it is an invalid reference.
What is the correct reference? Here is what i am currently importing:
Imports System.Data
Imports System.Data.OleDb

thanks,

WCGee

Hi,

1. Right-Click on the References in your Project.

2. Click Add Reference

3. Select the System.Windows.Forms

4. Click Ok

In Page

            
Dim Width As Integer = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width

Open in new window



OR

Imports System.Windows.Forms

You are working on a website (I assumed that by looking at the zones of the question) so leave the winforms namespaces alone. That will give you resolution of the webserver.

If you need to get CLIENT resolution in server side code, check following URL
