When I use this code I get the error "Property 'Chars' is 'ReadOnly'."
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 1 RepliesI've out an output rich text box called TbxOutput, and I have many different tbxoutput.appendtext("") methods in my program.I don't really know much about how to set rich text box colors, and what I specifically need is for a simple line of code that i can plug in before the tbxoutput.appendtext("" + vbnewline) methods to make that particular line output text of a different color.
For example, when my program normally outputs messages it does it in black, and i want it to remain that way by default. But when it outputs an error message, I want that particular message

View 25 RepliesI 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.

I have a GridView with image buttons for selecting rows. I am using an OnRowDataBound event to color selected rows Blue:
e.Row.ForeColor = System.Drawing.Color.Blue
Now that works great as long as I don't set a color either in the CSS stylesheet or on the grid Items themselves. If I do that, then all rows are colored that color and I don't get my Blue selected rows color for selected rows. I would like to color the text in the grid something other than black.

I have a rich text box and a fontDialog control. I am using it for the obvious purpose of changing the font of the text in the rtb, which I can do. What I would like to know is how, if there is no text selected inside the rtb, to make it only change the text that is typed after the change. I have already made it so that a selection can be changed independently but cannot make it change only text that is going to be typed if there is nothing selected.

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.
