I have this to append a text to a richtextbox
RichTextBox1.AppendText(String.Format("{0,-11}{1,-18}{2,-10}{3}", "[" & Now.ToLongTimeString & "]", "SergeMorel", "∙ Some Text Here", Environment.NewLine))
It's for an irc client. It appends the text users send or receive.How do I color for example, the time in a color & the user in a different color, etc...
var queryString = string.Format("filename={0}&filestream={1}&append={2)", fileName, Convert.ToBase64String(b, 0, bytesRead).ToString(), 1);
above line of code giving error 'Input string was not in a correct format.'
I have a function that is getting passed a String and a DataRow.The String is a custom formatter. The idea is to do this
String.Format(passed_in_String, DataRow("ColumnINeed"))
The reason this is being done is at this point we have no idea what the column contains.However, if the formatter is "{0:MM/dd/yyyy}" and the DataRow("ColumnINeed") is an integer containing 42, String.Format is returning: MM/dd/yyyy In this situation I need it to throw an exception instead of returning nonsense.Is there anyway to make String.Format throw an exception if the object does not match what the format string is expecting?
So I need a format string to pass to String.Format that would "move" the decimal point.I can't perform any math operations before doing the String.Format, so it has to work right off the bat.Basically I'm emulating a formatting string from a proprietary server. In it if I say:
"MR2"
for the value:
12345
The result is:
123.45
I'm close with this, but it's not spot on:
String.Format("{0:#0.##}", 12345)
an extra, but not necessary... there is also MR2Z, which moves the decimal 2 left, but if the value is 0 "" is returned.
however, i'm copying this directly from the book in its example format and still getting an error.

I need to take a string formatted like '010711' (DDMMYY) and put it into format '01-Jul-11'. Ive thought about doing something like string.toArray and then having some conditionals that format from there but am looking for an easier way.
View 5 RepliesI want to format the Timespan to have format like this 49 hr 34 mn 20 sec
I used the String format below :
String.Format("{0:00}:{1:00}:{2:00}", theTimeSpan.TotalHours, theTimeSpan.Minutes, theTimeSpan.Seconds)
It formats the Timespan to this format 49:34:20. How can I add hr mn sec to the String.Format above? or there's another easy way?
I am using String.Format("{0:C2}", -1234)to format numbers.is always formats the amount to a positive number, while I want it to become $*-*1234
View 4 RepliesI have a field that I display via: String.Format({0:c},amount) This produces the string "$28.28" However, when I try to convert back to a decimal amount, I get an incorrect format exception: amount = Decimal.Parse(amount.Text, NumberStyles.Currency) I also tried it with NumberStyles.AllowCurrencySymbol with the same results. I verified that the value in amount.Text is "$28.28". Am I missing something? Shouldn't these two operations use the same currency symbol and formats?

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>"

I have a program that appends text to a richtextbox.I do it like this :RichTextBox1.AppendText("[" & Now.ToLongTimeString & "] <" & Username & "> : Hello World !" & vbNewLine)
I know the username.Now, I searched google to color the username (the text between '<' & '>').It works, for the first line at least.As soon as I add another line, only the first line stays colored.How would I do that so it colors every line?
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 4 RepliesI have a bundle of tiny pictureboxes on a form. The number is specified by the user, but it could be up to 100, or so. The user can select any set of these pictureboxes by a variety of means. I want to change the image to show the selection state of the pictureboxes, and I'm looking for the best way to do that. The pictureboxes each shows a bitmap. The brute force method would be to have a selected image and an unselected image and just swap them, but it seems like there ought to be a way to do something significant and reversible to the image, such as inverting the colors, that might be smaller that having a second copy of each image.

This 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 ..
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.
Dim listbox1 As New ListBox
listbox1.Items.Add("<br/>")
Dim int As Integer = 0
Dim line As String = RichTextBox1.GetLineFromCharIndex(RichTextBox1.SelectionStart)
For Each item In listbox1.Items
[Code] .....
My coding selects an item from the list box and tries to color the words in the currently selected line, however, it often colors characters that come after the instance. Why is this happening?
I was wondering if it was possible to colorize syntax of, say HTML, inside of a RichTextBox by comparing each word in the current line of text against the collection of words in System.Web.RegularExpressions.AspCodeRegex? I'd imagine that from this question it would be possible?
