I'm adding a method to find and select text in my text editor. Everything worked fine, including the ability to find all instances of the text. My problem came when I tried to make it more user-friendly (doesn't it always?). Originally I had only a menu item with a shortcut( Ctrl + F) which invoked an input box.
Then I added a textbox and a button (similar to that seen in a web browser's Find() method) that calls the method in the same manner as the Find/Replace menu option and displays the desired text in the textbox. Everything works fine except that the text is not selected. I have MessageBoxes displaying the values of required variables in 3 places (marked ***FOR DEBUG ONLY***) to make sure that no values are being changed, but all variables are the same. The method still locates the text, but it is not highlighted.
I think it could have something to do with which object has focus. (When I click the button, the selected text loses focus?). But if I click everything with the menu items, it still works...

I'm developing an application in VB Express 2005 which should be able to open a pdf file and automatically find some text, select it, and eventually to drag it into another control (e.g. a textbox).Actually, I can open a pdf file by using a AxAcroPDF control. I can also copy and past some text, but I'm not able to find or select a text by my program.
I'm working with DevExpress GridLookUpEdit Control and I'm a bit stuck with it. Now I know you can't help a lot if you don't have access to it, but I'm trying to figure out why can't I do something like this with it:
GridLookupEdit1.DataBinding.Add("NullText", ds.Tables(0), "SomeField")It gives me an error, says it can't find NullText Property. This confuses me because NullText IS a property and I use it in my code to set the text inside the Editor.
I'm using Visual Studio 2008 and I split my text editor into two vertical text editors. I thought it would be useful to have a macro that re-size the active text editor to take up most of the screen but I haven't gotten very far. I get an error whenever I try to change the width of a text editor.
I'm fairly new to VB.NET, and I'm working on a text editor with a tabbed interface. I deal with large text files. Should I have each tab / text document open up in a new thread or a process? I basically want the entire application to always run fast as the text editor is just one part of it. If I have several large text files open I don't want the rest of the application slowing down a bit.

I'm working on a WYSIWYG Blog Editor, I'm having an issue with my text selection. I've added a couple of graphics to illustrate. My code is selecting the text and putting it back into the textbox, but it's adding extra text. I can't quite figure out how to get it to select the intended text and manipulate it correctly (make it Bold or Italic and so on,) and then show the text in the two windows (one is the Textbox and the other is a webtext box) correctly.
Below is my code and my 2 graphics.
Public Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click boldstart = "[ b ]" 'variables to hold formatting boldend = "[ /b ]" wboldstart = "<b>" wboldend = "</b>" clearrtf = ""
[CODE]............
Every thing works up to the point when I try to manipulate the text, it then puts more text in. I have been trying to find info on how to clear the text box and then re-insert the text with the text formatting. Side note in my graphics is a small graphic that is just there as a marker for me, it has no affect on the actual program.

I believe I need the code for Load Event. I have tried many ideas. I have searched the threads here and also google of course. No luck as of yet. Better description: I have a file named hello.txt. The contents of this text file are "hello". I use my program as the default for .txt files. I dbl click hello.txt. My program loads and the contents are blank and it should have "hello" in it.
I am trying to build my own website and realized that it would be a big help to also create my own vb program to enable me to embed tags with simple clicks of buttons. I am having trouble getting my vb code to be compatible with html code (I keep getting vb syntax errors).
Here is what I've tried:
<strong>'Inside of a button:Textbox1.text = "<html tag example></html tag example>"</strong>
I have a richtextbox that I paste a HL7 msg into and then harvest the message instance manually from the text, what I would like to do is automate the harvest of this integer to automate the selection process.

I have to produce a basic text editor with buttons along the top and a richtext box below. I am currently struggling with 'Save if changes are made' objective. At the minute clicking my exit button rather than close/X (something i have to disable but havent yet) brings up the do you want to save message box regardless of any changes and also, clicking the yes button does nothing.
CODE:
I recieve no errors and apologise if i have forgotten to include something useful
I am using a RichTextBox as a text editor. Each chr() has its own color. I am using rtfText.SelectionColor with rtfText.SelectedText. I have to, or I think I have to, Use For/Next Loops with Do While Loops to search for each Chr() using Mid() & InStr(). Of course this works very well but, it is waaaaayyyyy to slow.Some of the files can be over 8MB. Is there a better way? Am I doing this right?
I have a wrapper class created around TextBox, and I want to find out if there is any way to test if the vertical scroll bar is at the beginning (the very top) of the text box and at the very end of the text box.Alternatively, I will be happy if only I can find out a way to check if a scroll bar is enabled or not in a textbox (note: it's not a RichTextbox).
By enabled, I mean that scroll bar is actually enabled i.e. you can use the scroll bar to scroll the control, not just visible (I know we can check visibility by GetWindowLong)
I am facing an important problem with the LineShape control (installed with the Visual Basic Power Pack) . The problem is that in design time once I have "Sent to back" some controls (other controls, like text boxes), I can no longer select them! The controls get stuck on the form and I can't select them anymore! Even if I select those controls from the Properties window, I still can't do anything with them (like move them over the form etc). Right now I am using VS 2008. However maybe this problems doesn't appear on VS 2010?
For some reason i can't select text with the mouse in my application.Also my clients experience the same behaviour.I know it was possible to select a part of the textbox and it stayd selected. Now the selection dissappears and the cursor moves to the front.Only a doubleclick functions properly but selects a single word only.
As I'm sure many of you know, when you double click in a textbox, it selects part of the text, how could I make it where when you triple click on a textbox it selects all the text like a web browser address bar?
I want to select all text in a richtextbox excluding any images in it.richtextbox1.SelectAll() will select all objects in the richtextbox not only the text
