A quick way to convert RichText to HTML.

A window showing a Rich Editor and the resutling HTML code


This code was written to solve the problem of having RichText data needing to be displayed in HTML, both in HTML reports and in ASP.NET web pages.

Using the code

Use of the code is exceptionally simple. Simply create a new instance of the class and then use the properties to first pass in the RichText to parse and then use the html property to get the resulting HTML. (The code file for the class is attached to this article).

''Assume you have a RichTextBox on your 
''form named rtbFoo and a button named btnBar

  Private Sub btnBar_Click(ByVal sender as object, _
          e as System.EventArgs) Handles btnBar.Click
    dim r2h as new RTFtoHTML
    r2h.rtf = rtbFoo.rtf
  End Sub

QuestionCombined with RTBExVB Pinmemberbigbro_19858-Aug-10 21:29 
Hi, I combined your code with the RTBEx code found on the MSDN site. This generates a Rich Text Box control that has .System.Drawing functionality, which can be used to print the RTB contents.

So now with your code added, the Rich Text Box Control will also have an .HTML function which will return the HTML string.

I want to know if it’s ok that I post this and reference this to your page or would you like to post this? I'm sure other people will find it helpful.
