I am using a Rich TextBox in VB.NET and passing to a StringBuilder. I need to replace the New Line character from the TextBox with either a space or a comma. Problem is the standard codes for new line don't seem to be picking up this New Line character in this case. Is there a specific character used in Rich TextBoxes as the New Line?

I'm using a richtextbox in vb.net. I need to maintain the text formatting while inserting a new entry.I have this issue solved although I am having difficulty with getting a new line between my new text and the prior existing text.Most solutions online presume you're working with rich textbox. text which accepts controlchars.lf, vbcrlf, and chr(10)... even chr(13) adds one single newline.How do i get the newline in rtf formatting?I prefer to have the new text entered at the top of the richtextbox as a user should see the latest update first.In addition, if this can be done more elegantly, I'm open for suggestions.Where you see controlchars.lf is where I want an rtf-based new line to show up.

Private Sub DataReceived( _
ByVal sender As Object, _
ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) _

this displays in a text box the received data from a serial port. And it works like a charm but the data received has custom start and end of line characters. A line begins with chr(&H2) and ends with chr(&H3). What i want is on the text box those characters to be hidden and the chr(&H3) to start a new line.

How do we know if the textbox contains only newline characters? ie or if the user types in one or more characters, then a bunch of "newline" characters (CR followed by LF) and then goes back and deletes the original one or more characters leaving only the leading "newline" characters. I don't want to count the characters in textbox only if new line exists..

View 1 RepliesI want to insert a special character into a RichTextBox. The character is in a Medieval Latin font (Andron) which is installed on my machine.
When I open MS Word and select Andron as the font, then go to Insert Symbol, then scroll down till I find the symbol I want, I see that its Unicode value is A752, selecting it inserts it into Word OK.
Now, back to my VB2005 project: I have a RichTextBox on my form, and the Font is set to Andron. I have two buttons on the form. Behind the first button I have this simple
RichTextBox1.Text = RichTextBox1.Text.Insert(RichTextBox1.SelectionSta rt, "a")
Clicking this button simply inserts the letter 'a' at the insertion point, fine.
Behind the second button I have this
RichTextBox1.Text = RichTextBox1.Text.Insert(RichTextBox1.SelectionSta rt, ChrW(&HA752))
However, on clicking this button I get the ubiquitous square symbol, as if it cannot find that character, which is odd (to me) as the correct font is selected for the RTB, and that code is the correct code for the symbol I want.
Edit to add: I can now see that all characters up to Ascii (Decimal) 255 (which equates to Unicode 00FF) all display OK, but any value over that does not.

I am using a WPF richtextbox to create a syntax highlighter for code provided in a textbox. I want to have it automatically adjust the rich textbox as I am typing, using a thread timer I reset the contents of the rich textbox. I am trying to keep the cursor where it is suppose to be. I don't loose any text characters during the parse (except line breaks).
I don't know how to keep the caret position where the user has left it in the text. It defaults to the end of the document. I attempt to store the current caret position in the text and then set it to the document after I make my changes, however the error I receive is "Cannot set CaretPosition to be outside of RichTextBox." So I set the caret position to the bottom of the document.

Basically I'm writing a little piece of photo-editing software and I would like the user to be able to write whatever they want as a caption for the photo. VB then writes that text in a blank space created under the picture. Pretty straightforward, I've got it printing the text and it can adjust for height differences (i.e. multiple lines of text, smaller fonts, etc.).
My issues arise in the horizontal direction, I cannot make the Richtextbox large enough to represent the width of the photos (Some pictures have dimensions several thousand pixels wide and most monitors cannot display that many...) so I have used horizontal scroll bars (wordwrap off) to allow the user to scroll across and see all the text. Now what I would like to do is to set a limit to how much text the user can enter on a line (based on pixels to accommodate for various fonts/sizes) and it seems to me that setting the .RightMargin to just a little less than the picture dimension (to allow for padding) should do just that.
