Rich Text Box (Or Regular) Different Colored Lines?
Jun 5, 2011
I've out an output rich text box called TbxOutput, and I have many different tbxoutput.appendtext("") methods in my program.I don't really know much about how to set rich text box colors, and what I specifically need is for a simple line of code that i can plug in before the tbxoutput.appendtext("" + vbnewline) methods to make that particular line output text of a different color.
For example, when my program normally outputs messages it does it in black, and i want it to remain that way by default. But when it outputs an error message, I want that particular message

I have a rich text box ('RichTextBox1') and a button ('BoldButton'), and have it set up so that whenever the user highlights some text in the box and clicks the bold button, that text becomes bold. That much I've figured out...
Public Class Form1
Private Sub BoldButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BoldButton.Click
Dim Bold As New Font(RichTextBox1.Font, FontStyle.Bold)
RichTextBox1.SelectionFont = Bold
End Sub
End Class
But I'd also like to add the ability that if the user highlights text that is already bolded, then clicks the bold button, that text will go back to 'regular' font. In other words, I'd like the 'bold' button to be able to toggle between bold and regular font.

the question says it all, doesn't it? I was just wondering if it was possible to get only the displayed lines of text in a textbox. (Such as line indexes 1-15, to give an example.)

When I used (?mn)[+CMGL:].*($) it removes the whole text , when I use (?mn)[+CMGL:].*(

On the left side margin there are some colored lines (green and yellow). My program shows no errors, warnings or messages but when I execute the subroutine it seems to skip the rows with the colors in them.

but I am getting the error File format is not valid when i attempt to open any Rich Text file

I have a rich text box which I use in order the user is able to add pictures, coloured writing, different font etc... however I need to load specific text in the rich text box when the user load the Form.how I can add (I guess) the HTML to load this every time the user load the form.
P.S the text will change depending on who loads the form so I can not do a simple

I have code that when text fills a main rich textbox beyond the size of its dimensions - the vertical scroll appears and simultaneously vertical scrolls the main rtb and a second subordinate textbox.
If I have a couple lines of text and I scroll down a line(row) of text using the cursor I wish the subordinate rtb respond in the same manner i.e. scrolling down the same line(row) and obviously the lines of text underneath.

I don't know how to add colored text to a richtextbox.
To make already existing text colored, I have tried things like:
RichTextBox1.SelectionStart = RichTextBox1.Find("colored word")
RichTextBox1.SelectionColor = Color.Blue
RichTextBox1.SelectionLength = 0
..so it will change the color of the found word.
The problem is, when the "colored word" exists multiple times in the textbox, it will never change theirs color. It only searches for the first "colored word" and it wont affect the others.
It would be even better when someone knows how to directly add colored text instead of changing it when it's added.

I am trying to wrap my head around getting some blinking colored text and lasting for 3 seconds on the screen. I'm creating a game where you hit submit and if the answer is correct a label with popup and blink 3 different colors for about 3 seconds also a groupbox background color change. I have found many different ways on here how to do the blinking text. I just can't figure out how to do it for 3 seconds and then disappear. Here's a general idea of the code

So, I'm trying to make a RichTextBox which makes seperate words colored as you type them (like in Visual Studio itself ).The problem is, it's absolutely not working as I want and absolutely not the same as in Visual Studio.It's constantly running over the code each 500 milliseconds (by a timer), bugging the focus and selecting the words you want to be colored quickly.
Also, when you have something selected in the textbox,it constantly unselects when it runs over the code again (tried to fix that, but failed).So, can please someone improve this code (a lot, it's coded really bad ) so the user doesn't notice the words are getting colored?I put the words into an array with a different array containing the colors of the string array on the same index (Sorry for my "not so good" english.. But I'm sure you understand it ).

I need to constantly display large amounts of colored text in WPF or Silverlight, and I need the user to percieve it as showing up instantly.
Currently I'm doing this using a canvas and textblocks, one textblock per 80-character line, with multiple runs to a textblock to handle the different colors. There can often be 20+ runs to a line.
In a 45x80 grid of text, this gets a framerate of about 12 in Silverlight, which is sluggish. Oddly enough, it's even slower in WPF... I can only speculate that this has something to do with my dev machine's lousy video card. Maybe it's trying to hardware accelerate and actually slowing down because of it?

I am trying to put colored text into a list box. I use the following
Private Sub ListBox1_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles ListBox1.DrawItem
e.DrawBackground()
Dim myBrush As Brush = Brushes.Blue
Select Case e.Index

This works fine and dandy as long as I use 8 pt font, but when I change the font to 20 I get the following: How can I get the list box to display colored text in a large font?

I have written a simple script to get a bunch of lines from a text file (they will be filenames eventually) which are split by new lines and puts each one into an array..
Dim ary() As String
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If My.Computer.FileSystem.FileExists("C:MenuFiles.txt") Then
[code]....
The only thing I can do for now is either use the substring function to remove the first character from all array values after 0 but I don't like that because it's messy and what if the split "works" as I want it to one one of the lines and knocks of the first character when I don't want it to.

The text is black. then, i have a button which calls the dialogue "Notes" A dialogue appears, with a rich text box. the user should then be able to enter text into the box, click "OK", and the text entered into the Notes dialogue be inserted to the rich text box on the main form -- with the font colour "Red". The rest of the text in the main rich text box on the main form should remain black.

I'm Making a Simple syntax highlighter and I'm Doing the highlighting in the text Changed event of a RTB and for obvious reasons I can't re highlight the whole document each time someone presses a key so i highlight one line each time the text changes. But this creates a Problem. If someone pastes code into the RichTextBox It only highlights the last Line. So is there a way to get if the user typed the text in with his keyboard or pasted it from the clipboard in the text Changed event?

I came to a company that already has a fully grown project... but coders that worked here before me didn't follow conventions and didn't use parametrized SQL queries... as a result there is over 1000 places in a very huge project that can possibly be vulnerable to SQL injection...
I need to find a solution that will automatically detect if there is an SQL injection in the code. So, for example there is a form which allows user to enter comments regarding a product, which will be sent to database on submit... how can we make sure that a user didn't enter a harmfull query instead of a normal text?
Is there any advanced code/regular expression/magic that can detect if this text contains a piece of SQL query instead of normal harmless text? I will accept any links, pieces of code in any language or even commercial software that will do that for me.

everyone! I've been at this for a while, and I'm not sure how this issue can be resolved:I'm working on a project in VB.Net, and I have a form with a rich text box. I have a groupbox with 4 radio buttons inside that are intended to change the font color of the text. Coincidentally, I have to repeat this same functionality for a 2nd set of radio buttons that would change the text font family.
At any rate what I've only been able to do is the following to successfully change the font color of whatever text I highlight in the rich text box:
Private Sub rbtnBlack_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbtnBlack.CheckedChanged
rtbxTextEditor.SelectionColor = Color.Black
End Sub
Private Sub rbtnRed_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbtnRed.CheckedChanged
[Code]...
Is there a way that I could write a sub (I'm assuming I would use a sub, since I don't think I need to return anything, thus eliminating the use of a function) that would handle the action of changing the selected text color in the rich text box without having to use a separate sub for each radio button? Mind you, per my teacher's specs, she doesn't use a button handler for any of this.

I have a text file containing lines of data (File 1). I need to delete all the lines in another text file (File 2), which are found in file 1.So I could read file 2 line by line. And then once the line has been read, read file 1 line by line to search for a match. But that's going to be painfully slow.Or I could read file 2 into memory. And then read file 1 line by line and REPLACE the lines in file 2 with nothing, therefore deleting them. File 2 could be 100 mb, so I'm not sure about reading it all into memory.
