i am trying to put a maximum row number of lines in a multiline textbox. What i want is to achieve something like a console, with a maximum number of rows, with the top rows to dissappear and to keep always the last i.e. 500 rows. a note: for the textbox text i use the following algorithm
dim text
textbox.text = textbox.text & vbcrlf & text
the problem is that after a certain number of rows the program starts to get a little slow. So i guess if i put a limit to the rows i will fix this.
We want to Replace some text from a textbox (multiline) with = the text in our combobox and we want to replace it with its new one (in a textbox)
heres our code
If TextBox7.Text.Contains(ComboBox1.Text) Then
TextBox7.Text.Replace(ComboBox1.Text, TextBox1.Text)
End If
so that says, If the textbox(multiline) contains whats in our combobox, then replace it with the text in textbox1..
I have a multiline textbox which is loading from a .dat file. However, despite telling it to load all of the .dat file, it misses off the end. I it copies the first large body of text and a load of spaces that are inbetween the first and second body, but doesn't load the second body of text. Here is the code I'm using to open my file:
RichTextBox2.Text = IO.File.ReadAllText("00061530.dat")
I'm trying to count characters in a textbox, which includes newline characters and tabs. How do we know if the textbox contains only newline characters? ie or if the user types in one or more characters, then a bunch of "newline" characters (CR followed by LF) and then goes back and deletes the original one or more characters leaving only the leading "newline" characters. I don't want to count the characters in textbox only if new line exists..
If String.IsNullOrEmpty(TextBox1.Text) Then
Label5.Text = 0
Else

View 1 RepliesI need to work with multiline textboxes. I am currently developing a web application that was started by someone else. The only problem I have is the text in my multiline textboxes is going to the next line before it needs to. I have played around with settings, removed the textboxes and added them back, and I am still having the same problem. When typing in the textboxes, the text moves to the next line after pressing the space bar.

I'm trying to iterate through each line of a multiline textbox. Something like:
For Each line In Me.txtBox1.Lines
Response.Write line.Text

I have a multiline textbox that while a file is read in some data is echo'ed out onto the textbox. Is is possible to programatically scroll the object down to the bottom? Changing everything over to a combobox and then changing the selected index would essentially do what I want, but the user needs to select/copy a bunch of lines.
View 5 RepliesI'm trying to make a textbox at runtime, Dim t as Control
t = New Textbox
t.Multiline = True
t.Size = New Size(300,120)
Form1.Controls.Add(t)
I found out that you can only size a textbox when Multiline is set true. And that's the problem. When I use t.Mutiline = true I get the error " 'multiline' is not a member of 'system.windows.forms.control' "
I've searched the internet for hours without result.
