So, imagine I have a RichTextBox control and a few buttons to allow the user to change the font size, set/unset bold, italic etc, and perhaps change the colour. Not much more than that. Can I then - in code - loop through the contents of the RichTextBox and determine which words are in bold or red or whatever, and where paragraphs start and end?
View 9 RepliesMy application appends incoming report data onto a RichTextbox control. As more text arrives from an external device, the thumb initially fills the trough and as times goes on, the thumb diminishes in size. This is expected behavior.A modal dialog box allows the user to cancel the file download but since it's modal, the user can't scroll down to see what the last text that was appended.Is there a property/event/method that will show the most recent/last text in the RichTextBox control, rather than the initial text as I have it displayed now? The user would be able to see the text drawn real time without having to use the thumb to accomplish

View 5 RepliesI have a richtextbox control. It contains many lines of text (multiline is enabled). My goal is: When user clicks with right-click mouse, I'd like to display all the text of the line where the cursor is. I'm using this method to get the cursor's line:
Dim line As Integer = RichTextBox1.GetLineFromCharIndex(RichTextBox1.SelectionStart)
But how do I get the text of the line? Should I copy the whole text to a string array , and then just print the relevant line item?

if RichTextBox1.Contains "begin" then
change "begin" to "begin".bolded
end if

While index <> -1

View 8 RepliesIs richtextbox can save a text within its control? What control in vb.net that could save the text being entered within its control paticularly, if any? I need somebody that could give me an idea on what control to use to save the text within the control. I'm not trying to save the text anywhere. I want to save it within the control. I don't have to save it with a filename and a path location. Just like this forum, which everytime you post and reply to a thread, you will have to enter your message in a certain workspace and after you submit, it will save within the control so everytime you open your thread you will see the messages. What control do I need to use in vb.net to do that? info especially the codes to save the text string within a certain control?

We are calling the api through .Net's WebRequest.Create; and when we pass in the URI it decodes it and as a result we can't get the data from the call.
