When I use this code I get the error "Property 'Chars' is 'ReadOnly'."
I'm creating a program that pings a host. I'm trying make text appear RED on one line if it's down, and GREEN if it's UP.
View 6 RepliesSo 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:
Richtextbox1.SelectionColor=Color.Black
I even changed it to this:
Vscrollbar1.Value=0
But still no difference.
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...]
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
[Code]...
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.
How can I change certain text's color (like Visual Studio does with "Public Class" or "Public Sub") is inside of a Rich Text Box?
View 14 RepliesI'm studying chemistry and wanted to make a quick app for studying the periodic table. What I have is 36 text boxes. I have a structure that can hold each of the 36 element's info, and an array with 36 instances of the structure.
Example:
Dim Elements(37) As Element
Structure Element
Dim strSymbol As String
Dim strElementName As String
Dim strNumber As String
[Code] .....
When I mess with it, sometime the text boxes will fill in, but randomly and the comparison between the input text and the info stored in the data structure never compare correctly. 90% of the time the structure data is showing a null.
I want to change the border color of a textbox. I have tryed to override the onpaint event (setting userpaint to true), but in this case I must control all the painting events of a textbox. So, this isn't a good thing. This seems to work, but the user control has no text property. And I woult like to override the gotfocus and the lostfocus events.

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.
