I have a program that will keep adding info to a richtextbox, I want to to autoscroll to the end
this is what I have vb.net Private Sub RichTextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RichTextBox2.TextChanged RichTextBox2.SelectionStart = RichTextBox2.Text.Length - 1 RichTextBox2.ScrollToCaret()
Return
End Sub
the problem is that it will go back to the beginning of the richtextbox2 then it will go to the end and it keeps jumping like that. If there a "smoother" way to do this? So it wont keep jumping back and forth?
I would like to romove any line that doesn't have "http://" Or "https://" within Richtextbox1.text.

View 5 RepliesI have a form that has a checkbox value for field 4. What I'd like a user to do is to be able to check that checkbox and when they fire the holidaysavebutton event, that my code will look for any of the checkboxes that are checked and save that line of data to my database. As the code stands now, I am able to get the first line to do this, but none of the lines after will save the data.

I have a list of strings in my richtextbox. I need a code to check if there are numbers in the first line, if there is then proceed with the rest of my code, else delete first line.
View 2 RepliesI need some kind of code to check if the first line in a richtextbox contains numbers or not.
Something like this:
If Richtextbot1.Lines(0) contains Numbers Then
Goto startbot
Else
[Code].....
If the first line contains 4 or more numbers, it will use it. After each loop it will delete line 1. So it repeats for the next line. When my code reaches the 3rd line, and it doesnt find 4 or more numbers it needs to delete the line.
