Selecting Particular Text From RichTextBox?

Jun 18, 2012

I have two RichTextBoxes in my vb.net application (rtf1 & rtf2). rtf1 is loaded with the external data. Mostly It contains para split into different sections. The paragraph is a dynamic data, hence the no. of words keep on changing. Now my question is that, I want to select a para from the cluster, copy it and paste it into rtf2.

Manually I did as, Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick

[Code]....

Here only i could find the starting position and length. without knowing the ending postion, i couldnot specify the number of characters. how to select "para content goes here is a multiline" only from the [para content goes here is a multiline]?

Actually the contents of Rtf1 is in the .txt format. But I knew only

My.Computer.FileSystem.ReadAllText("xyx.txt")

so, if i can select the para in the .txt file before reading it into rtf1, it will be more useful.

.net - Reverse Selecting Text Programmatically In A Richtextbox?

Mar 21, 2009

I have a form with a richtextbox and a scrollbar. I want to be able to keep appending text to the textbox without loosing my selection. I can save the selectionstart and selectionlength before I append the text and set it back and it works. The problem is when it comes to reverse selecting. The best I could do is set back the selectionstart at the right position but I have to move the mouse so it selects text again. I'm using the following functions before and after I append the text:

Private Sub StopRepaint()
Dim pt As Point
' Stop redrawing:
SendMessage(txtchat.Handle, WM_SETREDRAW, 0, pt)

[code].....

My main goal is to be able to select and copy text even when new text is being appended to the richtextbox. Anyone knows how to correctly select text in reverse OR easily fix my problem about text being deselected?

Forms :: Selecting The Underlined Text In Richtextbox?

Sep 24, 2011

i have a simple notepad application where i want a feature of selecting text which is underlined. Usually what happens is when i click a button the app reads a text file and underlines random text in the richtextbox. What i want is on the click of another button to select the text which is underlined. I thought of creating char range, regex all but not getting anywhere. I also dunno how to build a regex.

What i know is since all RTF texts are different we can choose the rtf text instead of simple text to select the underlined text. The rtf of underlined text in my application is this uli0 so manyulnonei where ul and ulnone mark the text as underlined. Now i want to select all such texts which are surrounded by uli0 and ulnonei . I thought of the following method :

1) Create another richtextbox2

2) Paste the text of richtextbox1 as rtf in richtextbox2. I mean show the text in coded rtf (like above) instead of normal rtf.

3) Use simple find to select all the text which is surrounded by ul and ulnone tags

4) process the text.

But this step is very tedious. If anyone could help me in making a simple procedure or build a regex which could process the text surrounded by those tags,

I am developing a search tool for my company. I got the searching to work and the results to append to a text box. I need to be able to click on the line in the text box and then open adobe or do etc. I can't figure out how to make the text box "selectable" I guess you could call it. Is there another way to do this or am I just missing a property?

Selecting Specific Text In A Variable?

May 22, 2012

I have encountered a small issue with coding a portion of my Visual Basic program. In my program, I have a variable that contains text data. I would like to be able to select certain text in the variable and place it into a textbox.

For example, my variable is called strCallInfo.

strCallInfo contains the following value:
Address: 123 Law Rd
Location Info: Carbon Police Department

[Code].....

Note that the values in the textboxes are equal to values in the string variable. The only problem I am encountering is how to sort the string and place certain values into specific text boxes.

Stopping The TAB Key From Selecting Text In A Textbox?

Aug 26, 2009

I have a program with several textboxes - some of the textboxes contain predetermined text that needs to be appended to later by the user.For example:Textbox1 contain the start of a case number as this is the same for every case number (EG: CA0000).When a user is pressing tab to cycle through the text boxes and gets to textbox1 it highlights CA0000 and the user can accidentally erase that when he types if not paying attention.Is there a way so that when the focus turns to Textbox1 it automatically sets the cursor at the end of any text in that box?

VS 2008 Selecting Text In ToolStripTextBox?

Nov 2, 2009

I am placing 2 of these on my form and want to do the following:

1. When the control is not Focused and the user clicks inside the control, I want to highlight all text within the control. I expect to use SelectAll() to accomplish this.

2. When the control IS Focused and the user clicks inside the control, I want standard actions to occur; i.e., the user can click-and-drag to highlight, double-click to highlight,

3. When the user leaves the control (clicks on something elsle), if the control is empty, I want to populate it with pre-defined text. If it's not empty, leave text as-is.

I'm having problems, though, with figuring out #1 and #3. I have tried Enter/Leave, GotFocus/LostFocus to no avail. With Enter/Leave, the text will highlight the first time a user enters the control, but I can't seem to get the program to think the user has "left" the control. That is, the "Enter" code will not fire again.

I also thought about using the Click event, but I don't want the SelectAll() code to fire for EVERY click in the TextBox controls.

Selecting A Random Button And Modifying Its Text?

Nov 13, 2009

I am making a game of tic tac toe, and I have 9 buttons lined up in a grid pattern. I want to select a random button for the computer to start the game from.

I have an array set up with all the names of my buttons, and I was thinking of picking a random entry from that array to start working from. This I have done fine, but I cannot change the text of a button. My code:

''# Define the array
random(0) = "tl"
random(1) = "tc"
random(2) = "tr"

[Code]....

as you can see, I can't simply do StartPoint.Text = "O", even thought StartPoint holds the name for the button.

Pan/change/move The Text Appended To A Richtextbox Control So The Text Itself Scrolls In Addition To The Scrollbars?

Jul 11, 2011

My application appends incoming report data onto a RichTextbox control. As more text arrives from an external device, the thumb initially fills the trough and as times goes on, the thumb diminishes in size. This is expected behavior.A modal dialog box allows the user to cancel the file download but since it's modal, the user can't scroll down to see what the last text that was appended.Is there a property/event/method that will show the most recent/last text in the RichTextBox control, rather than the initial text as I have it displayed now? The user would be able to see the text drawn real time without having to use the thumb to accomplish
