GeneralLittle Tweaks and VB.NET Source Code PinmemberTrickUK14-May-06 23:43 
Hi Hazem,
Nice work, saved me some time.   I've converted your source code to VB.NET (see below) and added a couple of tweaks.   I prefer to use System.IO.StringWriter when concatenating strings as the code looks less cluttered and easier to debug IMO (also means you don't need to be using the VisualBasic namespace when coding C# Smile | :) )
The only other notable alteration is when setting the ScriptPath property, where I simply added a check to ensure there's a trailing slash so the tags are rendered properly.   Caught me out on the first execution Wink | ;) .
Anyway, here goes;
Imports System.IO
Imports System.Web.UI
Imports System.Web.UI.WebControls
Imports System.ComponentModel
<DefaultProperty("Value"), ToolboxData("<{0}:calendarselect runat=server></{0}:calendarselect>")> _

      <Bindable(True), Category("Appearance"), DefaultValue("en")> _

                  myLanguage = Value
