Rather complicated question here. I am improving the text coloring in my custom RTB ontrol, and it is pretty simple:Quote:1. Disable drawing (SetDrawing(False))2. Get current selection
3. Select lines to colorize4. Process selection RTa Font object.
I am trying to color the text in a node in a treeview using Visual Basic 2008. I can easily do this by using the forecolor property (currentNode.ForeColor = Color.Red). The tricky part is that I want to color the text within the same node different colors. Here is an example of the string I want to color...
strStatus = "ReleasedGN, EditYW, StopperRD"
currentNode.Nodes.Add(strStatus)
I use the codes GN, YW, RD to indicate what color I want the text to be. I want the status Released to be colored Green, etc...
Is there a way to color the text within the same node different colors?
2008 Array Processing and Sequential File Processing
View 14 RepliesIm a college student and this is my first programming class, i am having extremely diffcult time with arrays and sequential file processing. Im not asking for the whole program, just something to get me started and hints along as i progress with it. Please help me get started on my program, its due in 2 days.
Here are the requirements....
1. The program must input any number of individual�s last and first names using two separate textboxes.
2. The array of names must be sorted by the last name using a bubble sort. You must code the sort.
3. The program must be able to recall the names from the file and add to the existing list of names so that more names can be added to, sorted, and written back to the file in sorted order.
4. Sort in ascending order: A to Z
5. All names must be displayed in a listbox in sorted order when the user wishes to see them.
6. In the listbox the last and first names must be separated by a comma and a space. Example: Smith, Mary
7. The user must be able to search for a name in the array, using the binary search algorithm. You must code the search.
8. Do not use module-level variables. Instead you may choose to use Static.
9. The program must be designed using Visual Basic 2008
I�ve a label which displays a time counter as follows:
Me.label.text = �Hrs: � & myH & � Mins: � & myM & � Secs: � & myS
The line:
Me.label.ForeColor = Color.Red
Changes the color of the entire text to red.
I�d like the letters H, M and S to be of different colors. I know I could set up three different labels and color them but I was wondering if exists a trick which allows me to change colors with the same label.
i'm working on a project app to help me color code my html snippets. i'm not being able to figure out how to change the color of this line when selecting text :
<font color=blue> synthax helper </font>
to look like this:
<font color=blue> synthax helper </font>
as far as i can get it to change the selection color is this:
<font color=blue> synthax helper </font>
here's what i have in code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
RichTextBox1.SelectionColor = Color.Blue
RichTextBox1.SelectedText = "<font color=blue>" & RichTextBox1.SelectedText & "</font>"
End Sub
Is there an easier way to color certain tags like: <html>, <h1>, <body>, etc?I would like to make an html editor and i would like to know if anyone out there has a VB10 Example of a text highlighter When the text changes.
View 1 RepliesI have a program that colors certain words, but when I do a Ctrl+Z, the textbox undoes the coloring. How do I make it stop undoing the coloring, and just the text that was edited?
View 4 RepliesThis is my second post and today I have the following problem:I want to make a Steam Gamertag Maker ..
1) I have a RichTextBox.
2) I have 8 buttons each representing a color (red, green, yellow, blue, teal, pink, white and black ..)
3.1) I enter some text into the richtext box.
3.2) I select part of the text.
3.3) When I press a button, e.g Blue and the selected text changes to that color.
3.5) I have a copy button, that copies the content of the richtextbox .. and that is where the problem starts .. (The copied text has no color and so on .
4) If I press, for example the Blue Button, I want that the following text "^4", is written just in front of the selected text and that the selected text is colored blue at the same time. The other text should not be affected by those adjustments ..
5) If the "^4" is inserted, it should be hidden
6) If everything is colored, I press the copy button and it should copy the whole text, including for example the "^4" ..
7) I want the "^4" to be hidden, because it looks better, but if I copy the content of the RichText box it should be included ..
I made a change to my program this morning which worked properly before. The Targetframework was set to 3.5 and I thought let's set it to 3.0 that threw in some errors so I changed it back to 3.5.. however that's giving me an error as well now :S This is the error:
module 'Resources' and module 'Resources', declared in'C:mijnmapmijnmap2Resources. Designer .vb', conflict in namespace 'Resources'. and it's pointing to the dovents line
How would I use his code and get it to work with a RichTextBox when a button is clicked?
View 1 RepliesI have an issue with Visual Studio's support for coloring User Types in VB.NET, I'm an C# developer that have been forced to code in Vb.NET by political rules in my organization, and I really misses the support for coloring user types in Vb.NET, I had hoped that this would be solved in Visual Studio 2010 and well in the beta they have added Vb.NET User Type coloring, but the coloring is the same for all user types I cant't have one color for interfaces and one for classes and so on.

Itemlists is a global lists i retrieved from database, everything looks fine to me but when i run this program, I found that the threads are inserting one records 9 times into the database(I have 9 threads in total), which makes me think that maybe i need to specifically assign 1/9 of a list to each thread? Is there another way to do it which doesn't require the splitting of the list, if not , how do i split it then assign?

I have an application that gets terms from a DB to run as a list of string terms. The DB table was set up with nvarchar for that column to include all foreign characters. Now in some cases where characters like ä will come through clearly when getting the terms from the DB and even show that way in the table. When importing japanese or arabic characters, all I see are ? Now I have tried converting it using different methods, first converting it into utf8 encoding and then back and also secondly using the httputility.htmlencode which works perfectly when it is these characters but then converts quotes and other stuff which I dont need it to do. Now I accused the db designer that he needs to do something on his part but am I wrong in that the DB should display all these characters and make it easy to just query it and add to my ssearch list. If not is there a consistent way of getting all international characters to display correctly in SQL and VB.net
I know when I have read from text files I just used the Microsoft.visualbasic.textfieldparser reader tool with encoding set to utf8 and this would not be an issue.

I created form2 in which there was a Label to display processing status text. In form1 right before serial port ran I used Form2.Show() and Form2.TopMost = True to display processing status. However only blank Form2 was displayed without any text inside, which means the Label in Form2 was not running. But after serial operation was done, the text in form2 came up, at which time I need to close it.

This is used for making notes, so you can keep adding notes on it until it's done.And I know this is not the 'best' way of keeping these records, this is the way how it was kept until now.So now my manager comes to me and asks to make a different structure of processing these notes.Because it is stored this way I can only retrieve full record from the database, but what I need is a way how to take for example only the 'top line' of it.Example:5/25/2009 8:45:49 PM Confirmation send
