Richtextbox Highlight Every Ten Lines?
Aug 23, 2011
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 am currently making a Syntax Highlighter.How can I highlight certain text inside a RichTextBox ? I am Currently Using This Code :
Public Function Highlight(ByVal highlightcolor As String, ByVal ParamArray WordsToFind() As Object)
'Loop through all the words you specified:
For i As Integer = 0 To UBound(WordsToFind)[code].....
but it will only Highlight 1 of the word I set / Change the whole text into the selected colour
Example :
'I wanted to Highlight "Hello"
'I put this code into RichTextBox_TextChanged:
Highlight("blue","Hello")
'And It will Only highlight The First "Hello" inside my Text :
'Hello my name is XXX, Hello
And, can I Highlight text between certain text / after certain text
Example :
'Highlight After the '
Or :
<!-- Highlight between these 2 tags -->

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?

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".

I 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.

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).

I am working on a way to determine if the lines of a RichTextBox have changed.I currently use this
Dim newhash As Integer = Me.Text.GetHashCode
If newhash <> Me._prevhash Then
Me._prevhash = newhash
Me._lines = MyBase.Lines
[code]....
But this method has a bad issue: The text property takes a while to "load up" plus getting its hash code adds to it. This code runs every time the Lines are needed (it is a property). So this
For i As Integer = 0 To Lines.Count - 1
Dim line As String = Lines(i)
Next
Takes ages to complete, because for every line it checks if the lines have changed.I am trying to evade using MyBase.Lines too much, since that REALLY takes ages to load.
- I can not use the modified property since it is unreliable (set to true if only a text color changes)
- Can't use the RTF since it changes without the text changing (coloring) and the hash code is slow as well.
- Can't use the TextChanged event, since it is sent after the SelectionChanged event (for some reason)
