Find Text In A Rich Text Box
May 29, 2010
I would like to find text in a richtextbox. I know the code to find a string, but.My find button is in a context menu.I thought it would be a good idea (which usually turns out not to be so good to have a text box in the sub-menu. So, the person would click on "find" and the side menu would open (with the text box), one would then type the search string into the textbox and hit <return>, upon which time the search would be executed.I'm not sure how to implement it. I'm starting to think there might be several issues since the menu system opens the textbox automatically etc. How will I get the string since the textbox won't be "called" by the find button.Can anyone give me some help as to how to procede with this method, or if this method seems daft, then perhaps point me to an alternate or 'standar' approach for this?

I'm attempting to the file the user has opened and find the text the user searches for in a MsgBox.It works fine as far as finding the text, however if you the user will click cancel it will just say "Text Not Found".I'd rather just have the box close like you would expect it to instead of bringing up the box.
Here is the current code that I have. Private Sub ToolStripMenuItem8_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ToolStripMenuItem8.Click Dim a As String

I am trying to open up a text file that contains some text. I have 3 text boxes on my screen. What I need to figure out is how to replace multiple words (1 in each textbox) with text it finds in the txt file.
I can do this by using the single find / replace feature but I'm trying to be able to fill out the 3 textboxes and then click my find / replace button to have my Regex find each predefined word and replace it with what is in the text boxes.
Here is my code to get the find / replace one word at time feature. I've tinkered with this to just add more variables to my Regex but it doesn't seem to work.

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
RichTextBox1.LoadFile("C:Documents and SettingsDesktopSigniture.rtf")

On the main form of my application, I have a Rich Text Box which is where the user will be entering information. 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?

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.

Okay, so what I want to do is directly output formatted RTF text to a Rich Text Box control in VB.NET. I don't want to find the text, select it and color it as it is not practical for what I'm doing. I've tried outputting RTF code but that isn't working either. Can I actually do this or will I have to write a dll?

I am working on an applictation to scan windows files to check for missing files, i have a couple questions on how to do this.I would like to use the %systemroot%system32 that way that it doesn't matter what drive letter it is, i'm not sure how to do this because when i tried it, it told me the file i was looking for didn't exist (in this case C:windowssystem32 undll32.exe) which does exist. Is there some way to use the %systemroot%?
Also, i am trying to print the resaults to a rich text box such as if rundll32.exe is missing put in the box "rundll32.exe is missing". How do I allow it to write it in the box, I tried the print command, but it didn't work.

I've been wanting to create a look like the attached jpeg Ive been looking around for a few hours for a solution to make text boxes transparent or have a background image. I've found a few projects on this form and elsewhere which include transparent text boxes, but every time I try to use it the way I need to--with the text box over a picture box--there are always various rendering errors. Most of the time, the text box is transparent if its just placed on the form (not over any other controls). But when I place them over other controls (like picture boxes), the 'transparent background' always take on the color of the form background.
This is one that I was trying to use. I found a few others around, but they all had the same render errors more or less.[URL]...I figured transparency or background images would have been supported natively. Anyone have any ideas? Maybe I missed something in my searches. I didn't really see anything which adds background images in text boxes (rich or otherwise). At this point, I'd just like anything that works, so it doesn't really need to have transparency--just a simple background image would be great.

In my program, I have retrieved several lines of text in RichTextBox1.text. I need to get a
name(without the colon) using a keyword that is on the same line.[code...]
Lets say I set a keyword "vacation" and I need the code to get the name Sara that is in the same
line.I have seen some tutorials that retrieve left, middle, right that gets maybe the last two
letters in the string etc but I need it to get the Name without the colon.

I'm trying to make a program that can do some statistics on text in a rich text box. I'd like to count the number of instances where text appears with a certain back color, for example where text is "highlighted" with yellow.
There seems to be no function to get the backcolor of text at a specific index, you can only get the backcolor of text which is selected, like this:
Dim backColor As Color
backColor = RichTextBox.SelectionBackColor
This means, by applying this nasty trick, I would have to manually select every character in the rich text box before I can find the backcolor:
For i = 0 To RichTextBox.Text.Length
RichTextBox.Select(i, 1)
If RichTextBox.SelectionBackColor = Color.Yellow Then
yellows = yellows + 1
End If
Next
However, this takes a very long time, because the program has to select and deselect every character.
What options are there to speed up the process? Disabling the paint event?

Is it possible to take certain text from a web page and paste it into a Rich Text Box in Visual Basic? I'm going to use this http://google.com/complete/search?output=toolbar&q=mlb to generate a bunch of keywords and I want to highlight just the keyword paste it into the Rich Text Box. How can I do this? Also a better way to describe this is almost scraping the keywords through all that code and putting them into the richtextbox.

I have a rich text box and a fontDialog control. I am using it for the obvious purpose of changing the font of the text in the rtb, which I can do. What I would like to know is how, if there is no text selected inside the rtb, to make it only change the text that is typed after the change. I have already made it so that a selection can be changed independently but cannot make it change only text that is going to be typed if there is nothing selected.

Hi, i'm trying to use the treeview to display the text of a rtf (rich text file) file when an specific node if clicked.HomeOMGWOOTFor example, if i pick OMG, i want the text of lol.rtf to be displayed on a richtextbox. But somehow i just can't manage to get it... I know to import the text of a .txt file to a textbox, but using the treeview makes it more complicated.This is the code im using right now:
Private Sub TreeView1_NodeMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick
Select Case e.Node.Index
Case 0
[code]....
Another thing is, that i can't import the *.rtf text into a richtextbox and i don't know why.
