Calling CodeHighlighterEngine from code...

Posted 18 years ago by David House

I have copied one of the examples on the forum, and am having the same problem.

Loading the SyntaxLanguage from XML has produced no change...


        Dim sLanguage As SyntaxLanguage = New SyntaxLanguage("SQL", False)
        SyntaxLanguage.LoadFromXml("H:\Windows\Addins\Templates\ActiproSoftware.SQL.xml", 0)
        Dim chEngine As New CodeHighlighterEngine
        ' chEngine.KeywordLinkingEnabled = True
        ' chEngine.KeywordLinkingTarget = sLanguage.ToString
        Dim text As String = String.Empty
        Dim inText As String = proc.Properties(proc.Properties.Count - 1).Value
        text = chEngine.GenerateHtmlInline("Proc", inText, sLanguage)

I have tried it with and without the commented lines...No change...

Get the following error:

System.NullReferenceException was unhandled

The variable inText contains the stored procedure that we are trying to format...

What am I doing wrong?
