Syntax/Command Trying To Implement Syntax Highlighting In RichTextBox?
Oct 12, 2011
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.
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;
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
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?)
Looking in the "Display Items" list in the "Fonts and Colors" section of options, I don't see a way to color code dates. I can color numbers, strings, comments... all kinds of stuff, are Date and DateTime hiding under something else?
I've been looking everywhere for a solution to this problem. I'm new to VB, well programming in general, and am using VS2010 ultimate. Everything has been running smoothly until recently. For some reason, there is no syntax highlighting for my code. All other code is highlighted and colored correctly, just VB is not. All i get is black characters. Keywords, comments, everything is black! I have attempted to reset all the settings, and I have made sure that the font settings are all set to default.
I recently set up a Redmine server for my time. Redmine's Wiki uses CodeRay for syntax highlighting. However, most of my team prefers to code in VB.NET, which CodeRay doesn't support.Are there any plugins out there that offer syntax highlighting for VB.NET in CodeRay? If not in CodeRay, maybe through some other library (that could be integrated into Redmine)?
I am trying to build a simple syntax highlighter editor along with undo/redo feature. I have the code to syntax highlight the code on "TextChange" event but the undo/redo feature does not work.Any work arounds on implementing syntax highlighting with undo/redo?
i planned to write a syntax highlighting application for a C/AL editor. I have a tool which has a little autocomplete function in C/AL.At first i would test it in my notepad. I thought about this procedure.1. Start application (minimized in tray, defined match words)2. Open Notepad (my application notice it)3. While typing the application the color of my text changes in notepad
Dim listbox1 As New ListBox listbox1.Items.Add("<br/>") Dim int As Integer = 0 Dim line As String = RichTextBox1.GetLineFromCharIndex(RichTextBox1.SelectionStart) For Each item In listbox1.Items [Code] ..... My coding selects an item from the list box and tries to color the words in the currently selected line, however, it often colors characters that come after the instance. Why is this happening?
I'm trying to make a TextBox with syntax highlighting (for (HTML/CSS) in VB.NET 2008.I figured that if I use RichTextBox.Find(), I can color specific text, but then I need to call RichTextBox.DeselectAll(). The problem is that the the cursor jumps to the beginning of the RTB.
I keep getting a syntax error on the ExecuteNonQuery command. I am sure that the table names and column names are correct. Anyone see what I am doing wrong? Am I using any reserved words as column names or something?
Dim da5 As New OleDbDataAdapter("SELECT JobPlanNumber, SLPartNumber, Quantity, Order FROM tblSLMaterials WHERE JobPlanNumber = ?", cn) Dim ds5 As New DataSet
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?
when 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,
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 an Access DB that lists customer details in a datagrid and in textboxes, when I use the edit button I can edit in the textboxes and when I click save the record is saved and shows in the datagrid. But when I exit the program I get "Syntax error in update command" Im not sure why because there are no errors in the error pane at the bottom
This is the code for save button Private Sub btnSave_Click(ByVal sender As Object, ByVal [Code] .....
I seem to be having a problem when attempting to insert a new record into my database through vb.net. From what I can gather, there seems to be an error in the code that the command builder (cBuilder) is creating for me. [code]...
Note: This is not my code, I was just looking to edit it, but I run into this problem... "Syntax error, command unrecognized. The server response was: CLIENT AUTHENTICATION REQUIRED. USE ESMTP EHLO AND AUTH." (Bolded @ bottom)

I want to select some rows from a sql express 2005 table. I am using this expression: "Starttime >= " & dtpStart.Value dtpStart is a DateTimePicker But I am getting this error: Syntax error: Missing operand after '14' operator.
Private Sub RichTextBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RichTextBox1.TextChanged RichTextBox1.SelectionLength = 0 Dim words As New List(Of String) words.Add("Test")
SELECT dbo.Calls.Description, dbo.TicketRead.IsRead, dbo.TicketRead.UserID FROM dbo.Calls LEFT OUTER JOIN dbo.TicketRead ON dbo.Calls.CallID = dbo.TicketRead.TicketID WHERE dbo.TicketRead.UserID = 1 or is null
I want to get a list of all calls, but also a value indicating if the user have read the call. so I made when a user open's the ticket a new record is added in a special table. now if no user have read it then it's ok, but if just one user have read this ticket, then the other users don't have this call in the list..
just starting out to learn vb.net. I am doing so cuz i have some vba stuff i need to port.orry for the beginner question: translate this code I use in Outlook to vb.net? I know it's not complete, but I am stuck here.
Private Sub Application_ItemSend(ByVal Item As Object, ByVal Cancel As Boolean) Dim objNS As NameSpace im objFolder As MAPIFolder
The following is from a WCF sample I am working on.
<ServiceBehavior(InstanceContextMode:=InstanceContextMode.Single)> _ <Foobar()> _ Public Class Service1
I've never understood this and just used examples, but I would like to understand what is going on here. What exactly is the stuff inside the <> brackets? How are these related to Service1? I understand the ServiceBehavior is related to the hosting, but what about Foobar?
