View 2 RepliesThe 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

View 1 RepliesI have a richtextbox, and I want to highlight the lines in groups of ten, alternating colours every ten lines.
I know I need to use:
Dim lineindex As Integer = Me.RichTextBox1.GetLineFromCharIndex(index)
Dim first As Integer = Me.RichTextBox1.GetFirstCharIndexFromLine(lineindex)
Me.RichTextBox1.Select(first, xxxx)
Me.RichTextBox1.SelectionBackColor = Color.Red
However I'm not sure what to put in Select to get it to select the whole line, and I'm not sure how to get it to change colour every ten lines (to yellow)
How can I get the sum from richtextbox, starting at line -1 ? But the first line should compare with line1.This code adds a constant to all lines and passes the sum to another textbox.
Dim num1 As Single
Dim sum As Single
Dim Constant As Single = Val(txtLowerTol.Text[code]....
So a third textbox should sum with one line "offset".

View 6 RepliesI have a richtextbox, with random values in each line:
a1,a2,a3
b1,b2,b3
and so on.
This textbox stores the values in a jagged array after lostfocus. What i am trying to do, is for the user to have the ability to 'switch' values in each line if he wishes to do so. Each switched element becomes the first, and the first goes where the old value was. So it's basically a 'swap'. For example:Line1: a1,a2,a3 --> user highlights "a3", right clicks and a contextmenustrip appears with the option 'switch', once he clicks a3 goes where a1 was and a1 goes to a3. So the new Line1 would be: a3,a2,a1. After that if he switches a2, new Line1 would be: a2,a3,a1 Once the switch is done in the array, redisplaying the data in the RTB is not a prob.
How would I make it so that if someone presses a button, the richtextbox will have more then 1 line of text
RichTextBox1.Text = "Something like this, but 2+ lines"
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).
I'm working on a program that inputs a text box text into a RichTextBox via a button click. But when I click a button, it over writes the text that is already in the RichTextBox. How can I prevent this?

How to highlight multi lines in Rich Textbox and know which lines are highlighted?
View 8 RepliesI am working on a way to determine if the lines of a RichTextBox have changed.I currently use this
Dim newhash As Integer = Me.Text.GetHashCode
If newhash <> Me._prevhash Then
Me._prevhash = newhash
Me._lines = MyBase.Lines
[code]....
But this method has a bad issue: The text property takes a while to "load up" plus getting its hash code adds to it. This code runs every time the Lines are needed (it is a property). So this
For i As Integer = 0 To Lines.Count - 1
Dim line As String = Lines(i)
Next
Takes ages to complete, because for every line it checks if the lines have changed.I am trying to evade using MyBase.Lines too much, since that REALLY takes ages to load.
- I can not use the modified property since it is unreliable (set to true if only a text color changes)
- Can't use the RTF since it changes without the text changing (coloring) and the hash code is slow as well.
- Can't use the TextChanged event, since it is sent after the SelectionChanged event (for some reason)
How can I make a program so you click a button and select a File using a OpenFileDialog and click send on your computer and it will send the file to a different computer and then a SaveFileDialog will show asking where to save the file on the other computer. Oh ya I cant use WinSock or whatever becuase im using Windows Vista 64 Bit. I need it because I for some reason cant use printer sharing. It might be because im on A 64bit Vista Machine and I want to print a file off of a 32bit XP Home Machine.

Using Visual Studio 2008
I have a Listbox where i use OFD to list selected text filenames, can be multiple and from different drives
[code]...
I would like to be able to select more than one and have the whole of the lines loaded. I have tried many approaches, 'For each line' for example, but cant get my head around it. Another issue is that i would only like to see the textfile name in the listview box instead of path and filename.
I have a listview box. I load the listview up from a text file and everything is divided into three groups. I need to be able to select multiple lines then push that out to a single variable, separated by commas. Two things are happening that are problematic:
1) If I just have it set to smallicons and no checkboxes, anything I select is highlighted right up until the control loses focus at which point everything un-selects.
2) If I turn on checkboxes, I can click boxes and they stay selected when I lose focus BUT the checkboxes are cut off on the left side of the control. (The checkbox appears to go off the edge of the control.) There's plenty of space in the control for the checkbox and the listed items.
Im making a text based game that i need to randomly select different numbers of lines from a text file then pass them to a list box.[code]...
First the code needes to identify the 4th element then randomly select lines from lines that contain that element. The code needs to work out how many lines have a matching text to the 4th array then randomly select lines from that total no need for a maximum limit to that number.The same line must only been show the once at a time, but It can then be shown again on a different button click.[code]...
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.
