I managed to add lexems programmaticallyy in combination with a custum langua configuration file : one problem solved.

I don't know how i can remove a lexem. p.e.: i have a lexem with ' BeginBlock="abcde" ' and i want it removed. how can i do it?

I looked at the given link. Some parts I have already used. My application uses an xml document for the ever-present lexems. For this I use the code:
edcCODE.Configurator.Open ("F: \ VB2010 Proj \ Private \ PRIDE \ PRIDE \ PRIDE.PLC") edcCODE.ApplyConfiguration ("PROTON") for the lexems that are named by the end user I use the following code to add this: Dim currentConfigLanguage As IConfigLanguage = Me.edcCODE.Configurator ("PROTON") Me.edcCODE.ApplyConfiguration (currentConfigLanguage) Dim formatMethod As ISnippetFormat = Me.edcCODE.Language.Add ("CodeBehind") formatMethod.Font = New Font ("Garamond", 12) formatMethod.BackColor = Color.Green Dim own_lexem As ConfigLexem = New ConfigLexem ("Graphic", "", FormatType.Custom, False) own_lexem.FormatName = "CodeBehind" Me.edcCODE.Language.Lexems.Add (own_lexem) Me.edcCODE.Language.ResetCaches () this works as desired. both the lexems from the xml file are processed as well as the lexems via the code. What I have a problem with is to remove a lexem that has been added via the code. I tried to remove a lexem via
but I don't know what should be placed after remove.

Hi John van, 
Thanks for your update. 
We have checked your query “How to remove the lexems”. We suggest you to remove the added ConfigLexem from the Lexems collections using Remove() method. We have prepared the sample based on your requirement. Please find the code snippet, screenshot and sample for the same. 
Code Snippet: 
Added the configured  lexem 
After removing the configured lexem 
If you still face the issues at your end, please modify the above sample to reproduce the reported issue. It would be more helpful to proceed further and resolve this issue as earlier.
