i am making a lua editor that highlights reserved words and so.However I stuck in a highlighting part.I've made the reserver-words highlighting function but I got no idea how to make it highlight comment lines.
Could someone please help me? I want a function to search through the richtextbox and find lines that start with "--" and highlight them with green color.
I have a richtextbox, and I want to highlight the lines in groups of ten, alternating colours every ten lines.
I know I need to use:
Dim lineindex As Integer = Me.RichTextBox1.GetLineFromCharIndex(index)
Dim first As Integer = Me.RichTextBox1.GetFirstCharIndexFromLine(lineindex)
Me.RichTextBox1.Select(first, xxxx)
Me.RichTextBox1.SelectionBackColor = Color.Red
However I'm not sure what to put in Select to get it to select the whole line, and I'm not sure how to get it to change colour every ten lines (to yellow)

I can't find out the correct answer how to highlight words in hyperlinks using richtextbox.
The program which I'm creating is blueskycorp scraper which when type some words in text box and found links to my questions puts in richtextbox like links.
But the problem I can't find out untill is just how to highlight not words but links in richtextbox to match founded words and highlight them in richtextbox where is extracted links and only I want to mark these links.
In VB.Net, is it possible to highlight ALL instances of a phrase instead of only a single instance of it, for example: txtView.SelectionStart = txtView.Find("ERROR: Invalid command entered.") txtView.SelectionColor = Color.Red This would highlight "ERROR: Invalid command entered.", however if my RichTextBox text is: ERROR: Invalid command entered. < Only this line will highlight ERROR: Invalid command entered. ERROR: Invalid command entered. Alternatively, is there a way I can simply colour the line when I write it to the RichTextBox?

View 2 RepliesI am using vb 2010 and a windows form in my Web Browser project. In my favorites bar I need to be able to import my users favorites (that he may add) through a .txt file. I realize one way of doing this is creating multiple files stored in one master folder and reading the whole file of each which would contain the URL, but I would much rather have them all in one .txt file, but for that to happen i must read line by line from that file to import the favorites. Therefore, my question is how can I code my project to read through a .txt file line by line and return each line in possibly an array? "We are what we repeatedly do. Excellence, therefore, is not an act but a habit."

View 1 RepliesI have a listview box. I load the listview up from a text file and everything is divided into three groups. I need to be able to select multiple lines then push that out to a single variable, separated by commas. Two things are happening that are problematic:
1) If I just have it set to smallicons and no checkboxes, anything I select is highlighted right up until the control loses focus at which point everything un-selects.
2) If I turn on checkboxes, I can click boxes and they stay selected when I lose focus BUT the checkboxes are cut off on the left side of the control. (The checkbox appears to go off the edge of the control.) There's plenty of space in the control for the checkbox and the listed items.
I have a *.txt file which contains instructions and data, with its own comments (preceded by ! ), blank lines, and each instruction begining on a new line, but occassionally using two lines. Each instruction consists of several feilds seperated by a TAB. Finally each instruction ends in a comma. Only a few different instructions are there (10 different ones) but there are many of each. Spanning a good 2500 lines. Comments and blank lines are obviously of no interest to me. I merely need to read the instructions and the data that follows it.
Now, I have successfully used 'System.IO.StreamReader.ReadLine' to go through it line by line, picking out lines begining with certain strings (first 3 characters of a known instruction). All good, I can 'lift' out the lines of interest and store them, for them to be split up later (seperating their fields into instruction, data, etc..) and then into an array.
The problem is, since some of the data fields in these instructions are so long, it spans two lines, before it ends with a comma. Using the above method, I end up with two array entries for a single instruction, since I have stored individual lines rather than a complete instruction. The only similar situation I can tihnk of to explain this, is to pick out sentences in text, and store each one in a string. Of course these end with a period (full stop) but span two or more lines.
I am hesitant to post an example, since its formatting is rather strange, but it is generated that way from 3rd party software, so I cannot change that for my software application.Perhaps there is no 'graceful' way of doing this, meaning I would have to find a way of 'adding' the second line of the instruction, to the string of the first line. Or perhaps reading each line character by character, literally storing every number/letter until I reach a comma.
How can I get the sum from richtextbox, starting at line -1 ? But the first line should compare with line1.This code adds a constant to all lines and passes the sum to another textbox.
Dim num1 As Single
Dim sum As Single
Dim Constant As Single = Val(txtLowerTol.Text[code]....
So a third textbox should sum with one line "offset".

View 6 RepliesI have a richtextbox, with random values in each line:
a1,a2,a3
b1,b2,b3
and so on.
This textbox stores the values in a jagged array after lostfocus. What i am trying to do, is for the user to have the ability to 'switch' values in each line if he wishes to do so. Each switched element becomes the first, and the first goes where the old value was. So it's basically a 'swap'. For example:Line1: a1,a2,a3 --> user highlights "a3", right clicks and a contextmenustrip appears with the option 'switch', once he clicks a3 goes where a1 was and a1 goes to a3. So the new Line1 would be: a3,a2,a1. After that if he switches a2, new Line1 would be: a2,a3,a1 Once the switch is done in the array, redisplaying the data in the RTB is not a prob.
How would I make it so that if someone presses a button, the richtextbox will have more then 1 line of text
RichTextBox1.Text = "Something like this, but 2+ lines"
Using this [URL] to retrieve both address and place name at the same time ("//span[@class='listingTitle']|//div[@class='address']/text()[normalize-space(.)]"), I can get a list of placenames and addresses like this in a richtextbox:
jh ryder machinery limited
convenience storage ltd 3344 rideau
rd, gloucester, on, k1g3n4
kitchen interiors 146 colonnade rd,
nepean, on, k2e7y1
The first line is bad, it doesnt have an address. Line 2 and 4 are good, they have addresses. So what I could do is:Check each line,if the following line doesnt contain "numbers + ON" then delete line. This will leave me with PlaceNames followed by addresses, which I will then split every other line into a new textbox, (so I have one textbox with placenames, and another with addresses).
