Hey guys, I need some help.
I have a richTextbox and what I want to do is display somewhere inside my form the current line and column where the user is situated. Then considering the fact that the richTextBox is to be something like an A4 page, using the line value and font size and so on I want to somehow signal to the user the page he's on.
So? Any help please?

This might not be the best way to do it, but I played with it and it seems to work. If it's not quite what you were looking for it should at least get you started.

VB

Dim intLineNumber As Integer =  RichTextBox1.GetLineFromCharIndex(RichTextBox1.SelectionStart) + 1
Dim intCharIndexOfLine As Integer = RichTextBox1.GetFirstCharIndexOfCurrentLine()
Dim intCharIndex As Integer = RichTextBox1.SelectionStart
Dim intCol As Integer = Math.Abs(intCharIndexOfLine - intCharIndex)

Solution 3

C#

// Get current line index using char index of any selected text for that line
string CurrentLineIndex = richTextBox.GetLineFromCharIndex(richTextBox.SelectionStart);
// Get current line string from array of lines using the index
string CurrentLine = richTextBox.Lines[CurrentLineIndex]
