Change Color Of The Text In RichTextBox

Apr 10, 2009

Trying to change the color of more than one of the same text within a RichTextBox. [Code] The above code searches for, and changes the color of all "Boat"s found in the RichTextBox. There are a few problems, such as: If you were to go back to edit the RichTextBox and place your cursor in front of the, now blue word, "Boat" and type then all of your text would be blue. Also, the text you wish to change the color of in the RichTextBox MUST be Exactly the same as: "Search1", aka "Boat", capital letters and all.

Parsing Richtextbox Line Color Text?

Aug 17, 2011

Going in more depth currently over on MSDN on how to parse a color line to the richtextbox.

To explain more imagine you have various types of information. For example sake say a....

PRIVMSG
NOTICE
MODE

being parsed to the richtextbox. Now we have one sub to deal with all these three messages from the server but each needs it's own color.

Now currently i can only think about on each arrival of a new message loop the RTB length and match a a string.

Is there any way when we append to the RTB with the new string we can parse that new strings color also?

[2005] Adding Color To Text In A RichTextBox

Jan 24, 2009

I am opening an exe that launches in a hidden cmd window, and redirecting the text to a RichTextBox on a form. The problem is that the status messages in the cmd window are in color, but the redirected text in the RichTextBox has no color information and show as black on white. However, all the status messages in the cmd window have headers that could be parsed in some way so I can add color to them for my RichTextbox. For example, a message in the cmd window might read: [Warning] No settings file was found, using default values instead. This message is in Yellow in the cmd window.

Change Color Of One Word When Appending Text To RichTextBox

Apr 15, 2011

I'm trying to find a way to change the color of one word when appending text to a Rich text box. So if I append the sentence "This is a sentence with a specific word in one color" The entire thing will be in black except for the word "specific" it will be in red or any color I choose. The same thing will happen if the next line appended is "Please be specific in your request". All back except for the word "specific". I don't want the text added then someone has to click a button to change the color. It should happen as it's appended.

VS 2008 RichTextBox - Determine Lines Have Changed?

Apr 23, 2011

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)

How To Change Color Of Keywords In RichTextbox

Jun 11, 2011

If someone types in something like "red", I'd like the word's font color to become red. I tried something like this:
Dim red As String = "red"
Dim fnt As Font = New Font("Microsoft Sans Serif", 8.25)
If RichTextBox1.Find(red) > 0 Then
For Each _str In RichTextBox1.Text
Dim my1stPosition As Integer = RichTextBox1.Find(red)
RichTextBox1.SelectionStart = my1stPosition
But I dislike the highlighting-type approach.
