You probably got annoyed when you read the title, it must have been asked a million times. But unfortunatly I cant get it working for myself. Ive been using this code to highlight the word "var":
Dim search As String = "var"
Dim index As Integer = RichTextBox1.Text.IndexOf(search)
If (index <> -1) Then
[code].....
But it selects the word "var" and then afterwards, it makes thewhole RichTextBox have this font.
Using VB 2008r 2010 is there somehow I could make a syntax highlighter such as Notepad++?But maybe more simpler for only HTML, PHP and CSS? Or is there a plug-in or something you can download and add in your app?

I am having an issue trying to figure this out. I am writing a script editor that uses tabs (a tab control) and I want to implement syntax highlighting. My issue is that every sample I can find on syntax highlighting uses
Private Sub RichTextBox_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RichTextBox1.TextChanged
I've been trying to get syntax highlighting for a RichTextBox.I am struggling trying to code it myself, so I looked around a bit, and found a cool .dll file called ColorCode.
[URL]
So I went into my project and imported the ColorCode.dll file. (Project>Add Reference)However, I don't know how to use it!?Is there anyone out there that has used this .dll file?How can I use it to get Syntax Hilighting in RichTextBox1?
I have a richtextbox on my form and currently have made a simple syntax highlighting for it. It works great with a small amount of text but as the text amount increases it starts flashing and locks the textbox while typing.
This is my current code. I call the sub on the textchanged event.Basically what happens is I have a list of words that it checks for and if it finds it, it colors the word.

I'm building an app that has an sql editor with syntax highlighting and intellisense. I've got the frame, but i'm stuck with the re-coloring of the RTBSuppose the RTB has got a large volume of lines. when i start editing, the on-textchange event triggers the re-coloring of the current line. using;
- selectionStart
- selectionLength
- selectionColor

I need help Related to this form [URL]...Related to that topic Using the same code how can i add more then one color so how can i add it more then once So like words = the and bob ect... but I make a new dim call it words 2 = for next then ect... diffrent color I do this and it cancels out the blue the first one, so like this
[Code]...
So then i try it purple works but now blue does not..i know its possible with this one! All i want is to be able to add other words in a different color! Because this code works like a charm
I am currently working on a code editor program for Linden Scripting Language (Second Life Code) and I am having a lot of trouble using the Syntax Highlighting class which i have found on a website [URL] I dont understand, the Class inherits the System.Windows.Forms.RichTextBox so it should change the color of the text if i type one of the keywords shouldnt it and i should not have to do any codeing for the RTB (or do i?)
View 5 RepliesI have the following
Private Sub RichTextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RichTextBox1.TextChanged
Dim words As List(Of String) = New List(Of String)(New String() {"select", "insert", "delete", "truncate", _
"from", "where", "into", "inner", "update", "outer", "on", "is", "declare", "set", "use", "values", "as", _

The only problem is that if I type one of the key words, the word highlights, but if i type a word with one of the key words within it, part of it gets highlights as well.Example:
drop
dropped
I was wondering if it was possible to colorize syntax of, say HTML, inside of a RichTextBox by comparing each word in the current line of text against the collection of words in System.Web.RegularExpressions.AspCodeRegex? I'd imagine that from this question it would be possible?
View 3 Replieswhen i copy code from vb.net code window, and paste it in my richtextbox, the color synthax is as it displays in my vb.net code window.. this i want to keep when finding and replacing words. i have the following code to find and replace,
RichTextBox1.Text = RichTextBox1.Text.Replace("Private Sub", "<font color=blue>Private Sub</font>")
but the color syntax of the richtextbox code is lost, looks like a textbox's text.. how do i replace the words and keep the synthax coloring?
While I do know the above goal is rather challenging to achieve, I know it can be done.What the one I made does:It compares each word to a word from the list, if its a match, it will physically select the text and change the color, and finally it will return the carat to the position it was in when it highlighted.
Issues with this: Flickering. It always flickers. I managed to reduce the flicker by making the thread sleep for 50 milliseconds, but I could not get rid of it entirely (it didn't noticeably slow down typing either). Now, another thing that I tried was using a second RichTextBox to have the highlighting occur to that, but that made no obvious differences at all.Scrolling. It will scroll the RichTextBox if the amount of text is big enough to cause scrollbars to appear.Deleting text. If you delete part of a word which has been highlighted, itll retain the color formatting even if the word is now changed. Itll also physically select the entire word, which baffles me endlessly.Closing the window. Since the highlight subroutine is called whenever the RichTextBox's TextChanged event is called, apparently it is fired when the window closes? However, since the window is closing, it slows down the entire process, so with a larger file it may take 5-10 seconds to go through and highlight each keyword.
How can I solve each of these issues? I do not want to use someone else's component, I specifically want to use my own.Physically edit the RTF instead of using a built in method for changing the text color, this would get rid of all my issues. Assuming a keyword was "The" (for example), what would the rtf be to make it turn blue?Don't use syntax highlighting (last resort here)My end goal: A syntax highlighter for a RichTextBox which works as well as the one in Visual Studio.
EDIT: Is there another component which would be better for this than a RichTextBox?
I have used IsHighlighter property of InkCanvas to create highlighter tool In real life when we use highlighter it highlights on the top of our notebooks or books writing but in InkCanvas i am not able to highlight on the top of Ink which i have previously drawn I am creating application which have pen as well highlighter tool now if i have to highlight some thing which i have drawin onto InkCanvas using pen highliter goes down to Ink .
