VSTO - Use RichTextBox with Range

In VSTO project, we can use WinForm dialog with RichTextBox to allow user to input rich formatted text. The Rtf property of RichTextBox returns the string representing the content in Rtf format.

However, there is no direct way to insert the Rtf content into Word Range object. The Text property of Range object only accept plain text and there is no Rtf property in Range object.

After the long search and experiment, I found out that the only way to communicate between RichTextBox and Range object is via Clipboard.

From RichTextBox to Range:
    Private Sub InsertRtf(ByRef strRtfMessage As String, ByRef oRange As Word.Range)
      With oRange.FormattedText
          .Style = "Body Single"
           Clipboard.Clear()
           Clipboard.SetData(DataFormats.Rtf, strRtfMessage)
           .Paste()
      End With
  End Sub
From Range to RichTextBox:
 Private Function TransformRangeToRtf(ByRef oRange As Word.Range, ByRef rtfMsg As RichTextBox) As String
    oRange.Copy()
    rtbMsg.Paste()

    Return rtbMsg.Rtf
 End Function

Forms authentication ReturnUrl strange behavior and fix

When working with .NET forms authentication, I have found a strange behavior: For example, we have a web site using form based authentication. There are only two pages in the site: login.aspx and default.aspx. Default.aspx is the protected page. Without login to the site, if you type directly the URL to the default.aspx page with ReturnUrl as QueryString like this: http://localhost/YourWebApp/Default.aspx?ReturnUrl=Default.aspx Instead of redirect you to the login.aspx page, you will directly get http unauthorized error (401.2). However, if you remove the ReturnUrl query string or change it to something else, you will get expected behavior: redirect to login.aspx page. It seems .NET has some special treatment to ReturnUrl parameter. In order to fix this, we need to intercept the 401 response before it sends to client and redirect user to login.aspx page. In global.asax page, we need to add this event handler:         protected void Applica...
