Question How do I change partial text color from within an output string?

[mcapone888]

Hi everyone. I am a novice hobbyist with vb.net, so please excuse my terminology. I have a read only richtextbox, let's cal it rtbTest. I want to change the text in it at runtime to: rtbTest.Text = "I am running a test. Please wait." However, I want the word test to be red. I know the proper way to do this (using multiple line outside of the text property value), but (and I am hoping I am explaining this correct) I want to change the color from within the text string itself. So I want it to look something like this: rtbTest.Text = "I am running a " & Color.Red & "test" & Color.White & ". Please wait." or maybe even rtbTest.Text = "I am running a test. Please wait." I know these two snippets do not work, but I hope you understand what I am trying to do. I want to change just a portion of the text to a different color from within just the one line of the .Text property value. Is this possible? Thanks. (((Sorry - I am entered text with paragraphs, but my post is being stuck into one big paragraph)))

Use Select method where you input start index and length of text to select, then set color of selection with SelectionColor property.
RichTextBox.SelectionColor Property (System.Windows.Forms)
TextBoxBase.Select Method (Int32, Int32) (System.Windows.Forms) (this is a base method, RichTextBox has same method)
Last code sample also shows a way to find index of a search string, if you need that.
