VS 2008 - How To Display Colored Text With Large Font In ListBox
May 14, 2009
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
[Code] .....
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 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 new to VB.Net, but I can tell you so far I love programming. That said, I'm building a tool basically to parse and display simple plain text log files. I'm hitting one stumbling block that really has me frustrated.
Other tools are able to load huge log files (500MB even) in a number of seconds. My tool, basically hangs loading a file that is maybe 5MB.
I'm using the MyString = StreamReader.ReadToEnd to read the contents into a string, and then RichTextBox1.Text = MyString to display the contents. That said, I really want to display the contents in a datagrid, but there has to be a better way of doing this?
How can I get my application to load larger files and display them faster? What am I doing wrong?

I am trying to make a calculator program. I would like the display(text box) to have a white background, with black font. So I set the "enabled" property of the textbox to "false"(because I want it to display, not receive input) and then choose the background colour to be white. In the form designer, the text colour is black, which is what I want.But when I start debugging, the text becomes the colour of the form. How can I make the font black?

Within our application, some of the object's text are effected by users with "Large font" turned on under Control Panel>>Graphic Properties. I can't determine what is the trigger to this behavior. I have many forms including TableLayoutPanels, ComponentOne Sizers, some objects with DOCK=Fill, and AUTOSIZE=TRUE. I wrote a simple Hello World form, and it is not impacted by the "large font" setting.

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'm working on a .Net Windows application. All the controls arrange fine, but when the user specifies their Windows display text to be larger than the Windows 7 default of 'Smaller', the controls get moved around on the form and makes it unusable.
Is there a way to lock down those controls no matter what the display text setting is at?

I was thinking a list box? but I'm not all too sure on how to use one. I'd like the user to be able to scroll down through the list OR use a search. How could I search the list?(Id use a textbox as what to search for and a button to search the list.)

What I want to do is display large amounts of text and a few pictures, ideally with hyperlinks between the pages. A lot like wikipedia really, lots of similarly arranged pages, text in categories with in-line hyperlinks and the occasional picture to illustrate a point.But not online, integrated as part of a larger app.
How would it be best to go about doing that? The display method is sortof dictated by the storage method. My thoughts were:
Lots and lots of labels stored in an Access database
Straight HTML as if it were a webpage embedded in an iFrame or something
Labels populated from XML files?
Program the whole lot in Flash or something else (A language I can't speak)
This is only a mockup for demonstration purposes so the priority is user-friendlyness and ease of programming rather than storage concerns or good programming form.

I have two listboxes. One for unselected bound to a datareader and one for selected. It can move all, some back and forth. I have the move buttons in an update panel and generate a report on a button click. I have this working fine. What I need to do now is color the items red or blue based on a third value from the datareader. Then add buttons to move all red >> / << or all blue >> / << Unfortunately, I can't post the code. I'm using VB.Net 2.0.

I have a list box being populated from a text file. If I have the listbox's font a fixed width font (Courier New) then the ends of a few entries get cut off (strings are 105 and 107 in length), but when I change he font to a none fixed width font (Verdana), the entire string shows.
If I make the listbox wider than that of the longest entry (with fixed width font) then the entire string shows.Just wondering if anyone had an explanation for this behavior.

I'm creating a basic text editor and I wish to include the option to change the font, font colour and background colour of the text box. Is there a way I can ask VB to display a font/font colour selection box or do I have to populate a combo box and code it all myself?

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
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

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

if I want to submit a large amount of text to my asp web page, do I need to worry about the text itself such as containing "&a=" that would mean another variable is being assigned for submitting data? Any way of not worrying about this? Or do I need to replace the & symbol everywhere in the test first if used?
