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

Private Sub RichTextBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles RichTextBox1.MouseMove

Select A Line Of Text In A RichTextBox?

Jun 13, 2010

I have a RichTextBox in a VB2008 Windows Form application. The RichTextBox has tabs set at 250 and 400. The following code snippet is used to populate the RichTextBox using the result of a LINQ query.

rtbData.AppendText(String.Format("{0}.
{4}{1}. {4}{2}{3}", strTitle, strAuthor, strBook, ControlChars.CrLf, ControlChars.Tab))

I've noticed that most of the time it takes several mouse clicks to highlight a desired line of text in the RichTextBox. Is there some code that will allow selecting the entire line that a user clicks on? The length each line in the RichTextBox is not the same.

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).

.net - Regex Replacing Non-words Chars In Strings, Ignoring Specific Chars?

Oct 8, 2011

In VB.net I've got the following line that removes all non-alphanumeric chars from a string:

return Regex.Replace(build, "[W]", "")

I now need to extend this to remove non-alphanumeric chars that aren't [] or _. I've changed the line to:

return Regex.Replace(build, "[W[]_]", "")

However I'm pretty sure that this says

replace non-word or [ or ] or _

how do I negate the tests for the [] and _ chars so that it says

replace non-word and not [ and not ] and not _

Some examples:

"[Foo Bar_123456]" => "[FooBar_123456]"
"[Foo Bar_123-456*]" => "[FooBar_123456]"

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).
