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 count the lines in textbox1.text (with multiplelines). I don't need to count each character. I only need to count each line from top to bottom in textbox1.text (multiplelines) and I will use Label1 to display the numbers.
example:
1-pauljaones
2-tommyperrry
3-marktoms
4-Jonessmith
5-paulwhite
Obviously this is 5 lines and that's what I need to count.

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.

I have a Richtextbox.Text in my project and I need to save all text lines into a ListBox.Text .
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.
I want to draw string in multiple lines and and I want to know how many lines given string will take. I am using following method.

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).
basically ive tried a few different methods which i have come accross by searching but none seem to work.
code so far after removing everything that didnt work is as follows
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
End Sub
End Class
im makng a spelling test type application so that each word is on a different line and that are displayed in a random sequency.
I 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)
i have one project (let's call it project1) that is going to add properties to another project's class. The thing is I wanted to make it automatically. So in my project there are two lines of code which I want to add at the bottom of the class.vb or class.cs in a project called project2. Is it possible? If so, how?It is a data access builder software which after adding some new columns to our database we use it to generate its properties and its parameter to be added in BLL. Since we do it often (changing our database structure) I did not wanted to copy data from data access builder software and add it to project2 manually.

I using MS Access 2003 Database with VB.NET.
I have wrote a SQL statement to insert the RichTextBox(RTB)'s text into the Access DB but got error saying syntac error. I cannot figure out what went wrong.
When inserting data for RichTextBox, i use the TEXT property- rtb.Text . usign rtb.RTF also got error. The data type in Access is :Memo ( to store larger size text ).

"Specified Visual is already a child of another Visual or the root of a CompositionTarget."

I know where the problem lies, its with the Canvas1.children.add(line), cause its telling me the line variable is already been used or in use on the canvas, I'm just unsure of how to turn that into a solution that will allow me to click the button a hundred times or more without being forced to MANUALLY make a hundred or more individual variables to store the line.
