Word Wrapping - Cannot Select Last Line Of Richtextbox (when A Line Is Wrapped It Becomes Two Lines)

Jul 5, 2009

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

VS 2008 Reading RichTextBox Line By Line - Splitting It?

Jun 16, 2009

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).

Delete First Letter In RichTextBox?

Sep 14, 2010

Currently, the user must first type in the driver they're new folder is located in (Like C , D , E , ect). This then takes them to where the pre-determined folder is located. However, my friend decided to make this harder for me. He now wants the user to be able to change the 'pre-determined' folder.

As you can see, they type the driver name in and then it sends them to a path that is in the richtextbox. However, with them now being able to change the path if they like, the thing looks like this.. (If they decided to browse for a new path)[code]...

Delete Invisible Text From Richtextbox?

Apr 10, 2010

I'm using a richtextbox which contains some invisible text; this is so I can have the user add a hyperlink - the code inserts the hyperlink as invisible RTF text after the link text. The problem I have is trying to delete the hyperlink - if I try and set the selectionstart and selectionlength to select the hyperlink, they ignore the invisible part (which is all of it).

So, how do I select the invisible text so it can be deleted? - I have the appropriate index and length available. An alternative approach is to somehow map the index to find the location in the rtf property of the RTB and delete the text in there;

Delete Lines In Richtextbox That Fall Under The Condition?

Sep 11, 2010

Using this [URL] to retrieve both address and place name at the same time ("//span[@class='listingTitle']|//div[@class='address']/text()[normalize-space(.)]"), I can get a list of placenames and addresses like this in a richtextbox:

jh ryder machinery limited
convenience storage ltd 3344 rideau
rd, gloucester, on, k1g3n4
kitchen interiors 146 colonnade rd,
nepean, on, k2e7y1

The first line is bad, it doesnt have an address. Line 2 and 4 are good, they have addresses. So what I could do is:Check each line,if the following line doesnt contain "numbers + ON" then delete line. This will leave me with PlaceNames followed by addresses, which I will then split every other line into a new textbox, (so I have one textbox with placenames, and another with addresses).
