I know it seems like a simple enough question, but I can't figure out how to get and set the current line of text. Say line 4 is "Hello World", I want to be able to recieve that this says "Hello World" then switch it with something else if need be.
is there a way to change the cursor position to the beginning of the another line in a richtextboxfor example, if i'm on the second line, i want code that will transport my cursor position to the beginning of the fourth line, etcfrustrated visual basic user
How can I do some code when the user changes what line the caret is on? So something like: sub textbox1_lineindexchanged (byval ....) Handles Textbox1.Lineindexchanged 'do code based on the current line end sub I am using a richtextbox, just I always used it so I just call it a textbox.
The following code selects a line ina richtextbox. It works OK expect from one problem:
When a line is biger than the size of the richtextbox, it wraps it. This create a big problem as I can not select the last line of the richtextbox (when a line is wrapped it becomes two lines). When I set wordwrap to off it works just fine
Private Sub RichTextBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles RichTextBox1.MouseMove
To read any form's text (except RichTextBox) line by line I've always used this splitting
Dim Lines() as String = Split(TextBox1.Text, vbNewLine)MsgBox(Lines(0))This code just works perfectly.But whenever I try this code on a RichTextBox like this:Dim Lines() as String = Split(RichTextBox1.Text, vbNewLine)MsgBox(Lines(0))The message box appears with the whole lines.I think maybe the RichTextBox1.Text() returns another new line character (means not vbNewLine).

I am trying to write out to console a percentage of data loading. I tried to use C# syntax which would be Console.Write(" Percentage: " + nCurrent + "/" + nTotal; however in VB I get the actual character 'r' being displayed in my string. Is there a special code I need to insert in order to update my cursor to the beginning of the line so that I may reuse that line?
Is it possible to (programmatically) retrieve the current line of code being executed? For example, I have program X that's only 200 lines long. Is it possible to tell a user "The current line of code is: ....."?Mods - Please do not mark my posts as answered. It is extremely rude. You have no idea if you've answered my question.
I WILL come back and mark the ones that are answers, as answers.
