Im currently faced with a problem. I have a textbox whereby the user would enter a word, my program would then match the word within a text. If there is a match, the program would display the word and the line that contains the matched word in the listbox. My problem is I want to highlight that particular word when the line is displayed in the listbox but I could not find any syntax that could perform that function.

I have a datagridview and the user wishes to key some text in a text box and press a find button.The text to be looked for could exist in any columns in the grid (I want to exclude hidden columns).The search is to start at the row the user is currently at. If it gets to the bottom of the grid and still not found the the search would start from the first row of data.
If a match is found then the row with a matching value is to be highlighted.I've looked at using the position and find properties of my binding source but I think this will only let me find on one column and only from the top?Do I need to programmatically loop through the rows in the datagridview and search for the text or may there be a better method?

I have a listbox where each line contains a short 3-4 character model number followed by a tab and then the product name the model number corresponds to. I also have a textbox which I am using to search the listbox.
The code I am using so far works somewhat, just not exactly how I would like. If I enter search text it will highlight the results in the listbox but only for the first characters, is there anyway to search the text of an entire line (index) of a listbox?
Right now I am using the following:
Private Sub txtSearch_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtSearch.TextChanged
ListBox.SelectedIndex = ListBox.FindString(txtSearch.Text)
End Sub

I am using this code:
[Code]...
It even indicates if the string I'm seeking is in the middle of a line. But what I would like is for the routine to highlight the line that that string is in and ensure visible. I can do that with another routine that uses an integer, but then the whole string(line) has to be the searchString. I've tried combining the two and even calling a Private Sub but with no success:(What is the best way to do this? Also, how do you get around doing it when the searchWord in in several lines?

The code below creates a highlight rect on each of the selected items in a listbox. How can I do the same without selection but rather on mousemove above an item?
Private Sub ListBox1_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles dialogue.DrawItem
If e.Index <> -1 Then
e.DrawBackground()
If (e.State And DrawItemState.Selected) = DrawItemState.Selected Then

I have a Web Forms textbox in a gridview and I want to higlight the text on a button click. textbox.select(start,end) doesn't work. Here is the code:
Dim row As GridViewRow = TryCast(DirectCast(sender, ImageButton).Parent.Parent, GridViewRow)
Dim txtdays As TextBox = row.Cells(2).FindControl("txtDays")
Dim lbldays As Label = row.Cells(2).FindControl("lblDays")

.Select works on Windows Forms textboxes but not Web Forms textboxes.

I'm using a WebBrowser control and I'd like to highlight text that the user enters. It's supposed to be kind of like what you get from Ctrl+F in Firefox. I initially tried this:
Me.webHelp.DocumentText = Me.strOriginal.Replace(Me.txtSearch.Text, "<span style=""background-color:#44F; color:#FFF"">" & Me.txtSearch.Text & "</span>")
However, if the user types "body" it replaces every instance of "body", even ones inside tags, which hoses the HTML. How could I separate the page text from the tags(and everything else) and just do a replace on that while maintaining the integrity of the HTML?

I am currently making a Syntax Highlighter.How can I highlight certain text inside a RichTextBox ? I am Currently Using This Code :
Public Function Highlight(ByVal highlightcolor As String, ByVal ParamArray WordsToFind() As Object)
'Loop through all the words you specified:
For i As Integer = 0 To UBound(WordsToFind)[code].....
but it will only Highlight 1 of the word I set / Change the whole text into the selected colour
Example :
'I wanted to Highlight "Hello"
'I put this code into RichTextBox_TextChanged:
Highlight("blue","Hello")
'And It will Only highlight The First "Hello" inside my Text :
'Hello my name is XXX, Hello
And, can I Highlight text between certain text / after certain text
Example :
'Highlight After the '
Or :
<!-- Highlight between these 2 tags -->

I've got a textbox and a label. In the label, I've got the string "alberto". What I want to do is, I want the charactes I write in the textbox to highlight in the label, so, for example, when I write "al" in the textbox, the first two characters will be highlighted.
So, the real question is: how can i highlight only some characters in the label instead of the whole text?

Here's my code snippet:
Private Sub txtLogin2_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtLogin2.KeyPress
'// Ceci empêche l'utilisateur d'écrire des caractères ASCII ou même des espaces..
e.Handled = Not Char.IsLetterOrDigit(e.KeyChar)
End Sub
It works fine and dandy except for one issue... the only way to delete text in the textbox using this is to highlight and hit DEL... But what if I wanted to simply back space... Any suggestions?

I need to highlight changes(diff) between 2 database text fields in a asp.net application. I'm used to "beyond compare" text compare, so the Ideal solution will do something like it, but if it just highlight the differences, that would be OK. [URL] The content is HTML, so if it could compare the HTML rendered text, it would be even better. So, i need a link or a control (free if possible) to do that job.

Is there a way to detect whether text inside a textbox is highlighted from a user using a mouse either by double clicking or click and drag inside a textbox? I'm able to use the mouse doubleclick event as a way to detect the double clicking. However, i am stuck with click and drag to highlight for more than two characters.

Does anyone know how to highlight or change the color of text inside a datagridview cell? Not change the back or fore colors of the whole cell, but only for a particular word inside the cell. This is to make the search results more visible to the user.I tried doing it in the Cell_Formatting event of the datagridview but I'm only seeing options to change values of the entire cell (e.CellStyle). If there was only a way to select text inside the cell and set the selected text's properties. Or if I could use some formatting tags around the text.
