Rich Text Box Font Color?

Apr 9, 2009

I have a program that checks for the color under the mouse pointer. I also stores what I think is the RGB (could someone confirm this?) value for that color in a Rich text box and next to that in a text box the coordinates of the mouse at that time.The idea is to be able to measure the times between the bounces of a tennis ball in a video. The background is black and the tennis ball is another color.I wasnt sure how to say "if color is not similar to black... Do this"So my plan was to set the richtextbox font color to itself - as it is an RGB value. But thats difficult, it wants to change ALL the text in the RichTextBox, not just the current Value.Basically Ideally I would like it if it recorded the times between significant changes in color of the pixel and displayed them.


Rich Text Formatting - Setting Font Size

Jul 1, 2010

I have created an instance of a Rich Text Box:

Dim RichText As New RichTextBox()
I was able to write to it using:

I was able to save the document to a file:


What I cannot find is how to set the font, and font size. IntelliSense doesn't help. Everything is "read only", meaning retrieve a current value.

How To Search For Texts With A Specific Font Size In Rich Text Box

Dec 24, 2010

How do I search for the words with the same font size (e.g. 15) in a rich text box and put the words into a list box? For example, consider a dictionary whose word entries are of size 15 and the rests are of 12. So how do I put all word entries into a list box and then the description (of size 12) in another list box. I am using visual basic 2010. I've tried regex but couldn't find a way of specifying the font size.Consider the bold letters of size 15 and the rests of 12.[code](physics) hypothetical truly fundamental particle in mesons and baryons; there are supposed to be six flavors of quarks (and their antiquarks), which come in pairs; each has an electric charge of +2/3 or -1/3

VS 2010 Button To Toggle Between Bold/regular Font In A Rich Text Box

Oct 1, 2011

I have a rich text box ('RichTextBox1') and a button ('BoldButton'), and have it set up so that whenever the user highlights some text in the box and clicks the bold button, that text becomes bold. That much I've figured out...

Public Class Form1
Private Sub BoldButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BoldButton.Click
Dim Bold As New Font(RichTextBox1.Font, FontStyle.Bold)
RichTextBox1.SelectionFont = Bold
End Sub
End Class

But I'd also like to add the ability that if the user highlights text that is already bolded, then clicks the bold button, that text will go back to 'regular' font. In other words, I'd like the 'bold' button to be able to toggle between bold and regular font.

One Sub Procedure / Change Text Color In Rich Text Box / Without Button Handler?

Oct 8, 2010

everyone! I've been at this for a while, and I'm not sure how this issue can be resolved:I'm working on a project in VB.Net, and I have a form with a rich text box. I have a groupbox with 4 radio buttons inside that are intended to change the font color of the text. Coincidentally, I have to repeat this same functionality for a 2nd set of radio buttons that would change the text font family.

At any rate what I've only been able to do is the following to successfully change the font color of whatever text I highlight in the rich text box:

Private Sub rbtnBlack_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbtnBlack.CheckedChanged
rtbxTextEditor.SelectionColor = Color.Black
End Sub
Private Sub rbtnRed_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbtnRed.CheckedChanged


Is there a way that I could write a sub (I'm assuming I would use a sub, since I don't think I need to return anything, thus eliminating the use of a function) that would handle the action of changing the selected text color in the rich text box without having to use a separate sub for each radio button? Mind you, per my teacher's specs, she doesn't use a button handler for any of this.

Changing A Fore Color To Black In A Rich TextBox?

Jan 3, 2012

So I have a Vertical Scroll which enables you to change the Foreground color of the highlighted text inside the Rich TextBox. Here is the code of the Vertical scroll named Vscrollbar1:

RichTextBox1.SelectionColor = Color.FromArgb(VScrollBar1.Value)

It does indeed work. Then I have a button that makes the Rich Textbox not Visible. Using Richtextbox1.visible=False Then I have an open button, which makes it Visible again. But what I wanted is that the text inside the Rich Textbox to be color Black; but the color of the from the scroll keeps appearing. Here is my code for the Close Button:


I even changed it to this:


But still no difference.

Weird Behavior Setting Color In Rich TextBox

Dec 17, 2010

I am adding characters to a RichTextBox one character at a time and setting the format of that character after it is added. The following code is a distillation of the actual code but reliably repeats the problem I am having.[code..]

While that is odd to me and unexpected, where it happens in the code is even stranger. By stepping through the code, prematurely going to the End Sub and then displaying the form, I was able to determine that when i = 3 and the line "Me.RichTextBox1.Text
= Me.RichTextBox1.Text & "S" is exceuted, the color of the first two "S" are changed from Blue and Red to all BLUE.

I do not understand.a way to add characters to a RichtextBox and set the formatting of those characters?

This example is just color. I the real project I am setting Size, Color, Bold and Italics. I do not know if the solution to this color problem will affect the other formatting information.[code...]
