I am working in VB.NET using Visual Web Developer Enterprise 2010 on an XP OS. I need to let the user download a file, but there is no reference to any dialog box or common dialog in the toolbox. I get a syntex error if I try to create one on the fly:

Dim Open_Dialog As New OpenFileDialog()

OpenFileDialog is underlined indicating a syntax error. It is also underlined if I delete the parentheses.

How do I install common dialog on the toolbox or create one at run time?

If you're using VWD then you're obviously creating a web application. The OpenFielDialog class is a Windows Forms component, so you don't use it in web apps. The user will be accessing your app in a browser and thus your app can't access their local machine. You would use a FileUpload control or whatever Web Forms provides and then the browser will be responsible for providing the UI to select the file to upload.
