I need to convert a plain text string into its URL form by encoding it.
This can be done in ASP.NET via the System.Web.HttpUtility.URLencode("string here") function, however an equivalent does not seem to exist in vb.NET framework 4.0
Any ideas on how to accomplish this?
It still exists... same place as it has always been:

The HttpUtility class is a member of the System.Web namespace and is declared in the System.Web.dll assembly, just as the documentation says. As such, to use it you must reference that assembly and, to use it unqualified, you must import that namespace. This worked fine for me:
Code:
Imports System.Web
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
MessageBox.Show(HttpUtility.UrlEncode("I want to encode this."))
End Sub
End Class
Note that, in VS 2010, a WinForms app targets the .NET Framework 4.0 Client Profile by default. System.Web.dll is, understandably, not part of the client profile, so it can;t be referenced by default. You must change the target Framework in the Advanced Compile Options to the full .NET 4.0 to access it. I haven't got VB Express installed to check but I would think that you'd have to have enabled advanced options to be able to do that.
