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.

I'm trying to find a few words and i want them to be for example in red.this is for a Html Editor. so i need it to list all words. for example i would need it to highlight "div", and "table", and lots of other words. all of them need to be red. or if it could highlight all words that are in "< >" would be amazing. iv been searching google and the internet for like 4 days. there is code out there but it will only highlight one word.

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.

With the intention of creating a program to interface with a serial port device, I recently started learning vb.net. To keep the structure neat the vb code has been split into two places; the first is the code behind for initialising, clicking buttons etc., whilst the second is for managing the comm port. Respectively, these are named 'MainWindow.xaml.vb' and 'ComPortManager.vb'.
In 'comPortManager.vb':
Dim RXArray(2047) As Char ' Array to hold received characters
Dim RXCnt As Integer ' Received character count

I would like to know how it's possible to append text between data.
For example:
I have a RTB with "ABC" on the first line and "DEF" on the third line. My question is how would I insert text data into the second line, without changing any existing data.

I am reading text from a file (*.TXT) 1 line at a time using streamreader. As I read that input, I am looking for specific starting and ending character strings ("<" and ">") . When I find those strings, I would like to select the characters between those string and have it set to BOLD and BLUE before appending that input line to the contents of a richtextbox.The only way I have found to do this is to first append the input line to the richtextbox then use the richtextbox.selection (color and font) methods to change the text.

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.

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?

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.

How can I replace character/word in text (loaded to richboxtext) but only for those which are not on the "block" list ?
Dim str As String = RichTextBox2.Text
RichTextBox3.Text = str.Replace("1"c, "A"c)
But I want add list of words which should be excluded. I thought that I can do something like :
Dim str As String = RichTextBox2.Text
If Regex.IsMatch(RichTextBox2.Text, "shows") Then
Else
RichTextBox3.Text = str.Replace("%"c, " "c)
End If
RichTextBox3.Text = str.Replace("1"c, "A"c)
Dim str2 As String = RichTextBox3.Text
RichTextBox3.Text = str2.Replace("2"c, "B"c)
But it's not working as it will just skip replace of % for whole text and I want just just exclude particular word from list from being replaced...
