I am using a RichTextBox control on my form. I want a small code which can detect if any image has been inserted in the rtb or not. (IDE VS 2008)
For e.g. user can just type some text or insert image also (Ctrl + V). Now if we select an image then we can get the type but I want a code which scans contents of rtb and gives me a true if an image is inserted or false if there is none.

edit: when I say at the end I mean completely scrolled to the bottom, not anywhere else.
I have a class library with a component class in it. Everything is in VB.NET. It's only one file so you can see it here [URL] . On line 92, there is the OnTextChanged Sub. I was thinking about adding ProcessAllLines() (as on line 128) to the end of that Sub, and it worked. However when I was typing in code to the RichTextBox (source which I used is here [URL] after each text change it was checking and processing ALL the lines. So I deleted ProcessAllLines() in the OnTextChanged Sub.I'm thinking about running ProcessAllLines() when the user pastes something to the SyntaksRichTextBox. However I do not know how to do that. I know that it should be something like:
If [CTRL Pressed] And [V Pressed] Then
ProcessAllLines()
End If
I also want it to be in the class library, not the application (Syntaks Demo).

I have tried all the tutorials I can find online and am still having no success getting an image from the clipboard to the RTB. I can accomplish it if I already know the image and path etc. and do it through code, but that will not allow someone to simply click an image, copy, and paste it into the rtb.

I'm working on a Vb.net project. I have a form with a RichTextBox or a simple TextBox control. It contains hundreds of text lines, so the control has to be scrolled.
I want to send to a printer only the lines that are currently seen on the control window.
That is, I want to convert what I see into an Image and then draw that image thru e.Graphics.DrawImage.
As you can see, it could also be the case of a ListBox, a TreeView or any other scrollable control.
How can I grab that rectangle area and then convert it into an Image? The rest I already know how to do it.
I just wanna ask, how to format an image or a picture inside an RTB control? Its like the way MSWORD does the formatting, (i.e Center, Behind Text, etc..).
