View 2 RepliesIn a .NET 3.5 application, i want to get caret position in a RichTextBox control. The RTB is not XAML. Also, the RTB doesn't have CaretPosition property as described here: [URL] What is the simplest way using which i can get the caret position?
EDIT:To be more specific i want to find out what is the position of the caret from the start of the line on which it is positioned. I can get the line number by using GetLineFromCharIndex(rtb.SelectionStart) but not the offset from the start of the line.
even Word Pad, when you scroll your Caret (the I-beam for browsing through text) through the text, in the font combobox, the font of the text you are browsing through will be displayed, and when you scroll your caret through a different font, the font will be changed. If you're confused, look at attatched picture.
I cannot seem to find a caret position changed event on the normal richtextbox control - and if anyone can show me a custom component with this it would help me a huge amount.So my basic question is how can i replicate the formentioned function in my own VB.NET program.No code is necessary just constructive suggestions, or links to other projects would be welcome.

I did a conversion of a VB6 project to VB.NET 2005 and some properties of a RichTextBox control weren't upgraded. I was wondering if someone could tell me an alternative or what to do about the following properties of the RichTextBox:
ZOrder - this worked in VB6:
formMain.textStatusWindow.ZOrder(VB6.ZOrderConstants.BringToFront)
SelColor - this worked in VB6 fo example: formMain.textStatusWindow.SelColor = RGB(207, 73, 10)

Win7 64 bit; fully patched VS2008 targeting FW2.0; VB.Net; running in Debug Mode (not tested in Release mode)I have a resonably complex app which I am refactoring a bit. As part of that, I relocated some code from a subroutine into a Click Event Handler. The Event Handler will, late in the handler, call the, reduced in function, subroutine. The point of this is thatNow when I click the button associated with the modified Handler I get:A first chance exception of type 'System.AccessViolationException' occurred in System.Windows.Forms.dll<br />With Error System.AccessViolationException Attempted to read or write protected memory.This is often an indication that other memory is corrupt.
