GeneralModification to Use Embedded Resources Pin

Nice work, this saved me a considerable amount of time.

I made a couple of tweaks to help in portability between projects. Specifically, I didn't want to have a Server Control that required the Javascript and CSS files to be copied into each project sepearately.

BTW - I also ported the code to VB, so the detail below will not match perfectly Smile | :)

To address this I put the files the Javascript files (from the Sourceforge project) into subdirectories alongside the server control. Each of these is set to be an "Embedded Resource" at compile time.

Next up I modified the AssemblyInfo.vb file to include these resource as follows: -

<br />
<Assembly: WebResource("Aardware.Impact.ControlLibrary.Calendar.js", "text/javascript")><br />
<Assembly: WebResource("Aardware.Impact.ControlLibrary.Calendar-Setup.js", "text/javascript")><br />
<Assembly: WebResource("Aardware.Impact.ControlLibrary.Calendar-EN.js", "text/javascript")><br />
<Assembly: WebResource("Aardware.Impact.ControlLibrary.calendar-Blue.css", "text/css")><br />
<Assembly: WebResource("Aardware.Impact.ControlLibrary.calendar-Brown.css", "text/css")><br />
<Assembly: WebResource("Aardware.Impact.ControlLibrary.calendar-Green.css", "text/css")><br />
<Assembly: WebResource("Aardware.Impact.ControlLibrary.calendar-System.css", "text/css")><br />

Finally, I modified the the script registration code so that it uses WebResources rather than explicit include statements. Similarly, I moved the code into the OnLoad event of the control so that everything is placed on the page in a logical sequence and is there when required.

The OnLoad event code looks like this...

<br />
Private Sub JSCalendar_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load<br />
<br />
  ' Register the JAVASCRIPT blocks<br />
  If (Not Me.Page.ClientScript.IsClientScriptIncludeRegistered("JSCalendarScript")) Then<br />
    Dim scriptLocation As String = Page.ClientScript.GetWebResourceUrl(GetType(DateField), "Aardware.ControlLibrary.Calendar.js")<br />
    Me.Page.ClientScript.RegisterClientScriptInclude("JSCalendarScript", scriptLocation)<br />
  End If<br />
  If (Not Me.Page.ClientScript.IsClientScriptIncludeRegistered("JSCalendarLang")) Then<br />
    Dim resourceName As String = String.Format("Aardware.ControlLibrary.Calendar-{0}.js", Me.Language)<br />
    Dim scriptLocation As String = Page.ClientScript.GetWebResourceUrl(GetType(DateField), resourceName)<br />
    Me.Page.ClientScript.RegisterClientScriptInclude("JSCalendarLang", scriptLocation)<br />
  End If<br />
  If (Not Me.Page.ClientScript.IsClientScriptIncludeRegistered("JSCalendarSetup")) Then<br />
    Dim scriptLocation As String = Page.ClientScript.GetWebResourceUrl(GetType(DateField), "Aardware.ControlLibrary.Calendar-Setup.js")<br />
    Me.Page.ClientScript.RegisterClientScriptInclude("JSCalendarSetup", scriptLocation)<br />
  End If<br />
<br />
  ' Register the CSS theme with the page<br />
  If (Not Me.Page.ClientScript.IsClientScriptBlockRegistered("JSCalendarTheme")) Then<br />
    Dim resourceName As String = String.Format("Aardware.ControlLibrary.{0}.css", Me.Theme)<br />
    Dim includeTemplate As String = "<link rel='stylesheet' text='text/css' href='{0}' />"<br />
    Dim includeLocation As String = Page.ClientScript.GetWebResourceUrl(GetType(DateField), resourceName)<br />
    Dim include As LiteralControl = New LiteralControl(String.Format(includeTemplate, includeLocation))<br />
    Me.Page.Header.Controls.Add(include)<br />
    Me.Page.ClientScript.RegisterClientScriptBlock(GetType(DateField), "JSCalendarTheme", "")<br />
  End If<br />
<br />
End Sub 'DateField_Load<br />

This removes the need for the ScriptsBasePath property and make portability easier - I only need to reference the library now, rather than worry about the scripts and style sheets.

The solutions works nicely for me and I can live the the small loss of flexibility in not being able to modify the Javascript and CSS files on a project be project basis.
