Supose i have two TextboxOne For normal Text and Second For After Replace textif i m Type some text in textbox 1 then Textbox2 show Its Replacement Text
I've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?
In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:
Dim user_data_file As String = "user_data.txt" edit_input = New StreamReader(user_data_file) Dim edit_line As String = edit_input.ReadLine
[CODE]...
However, I can't find any methods that will allow me to do this.
I have a bunch of object variables which are all initialised in their declarations such that:
Private _myObject As New ThisObject("SomeString")
where ThisObject is one of a number of object types, but all are initialised using a string.
I would like to use the Visual Studio Find/Replace dialog box to search for "As New" then replace everything from "As New" to the first set of speech marks with some text such that:
EDIT
My original example could be solved using other methods. This example is more representative of the actual problem:
Private _myObjectA As New ThisObjectA("SomeString") Private _myObjectLongName As New ThisObjectLongName("SomeString")

i want to change ALL the a's in the programs textbox1 to b's when the encryption button is clicked (button 1), remember when it is click it determines weather the text in textbox1.text is more then five, if so it goes onto replacing the a's if not, then it shows a error message?

How do I refactor the method GetInvoiceNumbers to replace the SQL String concatenation with the StringBuilder class? Here is my code:
Private Function GetInvoiceNumbers() As System.Collections.Generic.List(Of Invoice) Implements InvoiceService.GetInvoiceNumbers Dim invoiceList As New List(Of Invoice)
1. In the old VBScript, there was a compareMethod (binary or text, which with text, I could compare case) but I don't find anything like that in the new .Net Replace method. I know I can use the old way, but I'd like to use the new Replace method. I just need a choice of comparing case or not?
2. Let's say I have a long string, and I am using the Replace method - - it would be nice to get the count of instances replaced, and I'm sure that if I read line by line, I could actually get that count, but it would take to long.Is there a way, using the Replace method, to get a count of how many actual replacements were made?
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 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 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.

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 am working on a simple text editor for medieval Latin and I have a custom medieval Latin ttf that does exactly what I want. My question is: How can I embed that font into my text editor so that it can ONLY use that font, and so that when I send my text editor app to others they can start using it right away without having to download any fonts?
I have written a MDI Text Editor and I have written sub routines for print preview, cut, copy and so on, when testing my program, I click print preview when there are no documents active and the program crashes, the same happens with cut, copy, paste.
I know this is because I have not handled any error exceptions, the truth is im not sure how to.
I have got the code that makes print preview work with my mdi documents, but what code can I use or how can I add it to my existing sub routines to possibly show a message box saying something like "This Function Cannot Be Used With No Active Documents" something like that.
Could I use an If Statement? or Try, Catch, Block? - I am using a different computer as I am currently at work but if anyone needs the code I currently have for my sub routines.
I've found out how to change colours for the text editor, etc, but is there any way to change the colours in the help? It'd be nice to be able to have [for example] white text on a black background. It'd be easier on the eyes for lengthy reading sessions.No crops were circled, or animals mutilated in the making of this sig.
So, I was making shortcuts for a text editor I made. The first 3, that I originally included were control-b control-i and control-u for the bold italics and underline. That worked fine. Recently, I added control-s and control-o for save and open. I don't know why, but once I press control-s or control-o once, the control key seems to stay "pressed", so whenever I press just b, u, i, s, or o, they activate the commands. Here's my
I am writing a MDI Text Editor and I want the user to be able to change the language of the application i.e I want the text in the form and the controls to change language of whatever the user wants, I have built the sub menu needed for the languages, french, german, chinees and so on, but how do I code this??

I am doing a Windows Form Application assignment (Simple User Interface Text Editor - practically my own version of MS Notepad) for my VB.Net course... I have practically completed the project however there were certain items we had to add to one of the dropdown menus one being Word Wrap (Under the Edit drop down). I am really confused as what to do here for the WordWrapToolStripMenuItem_Click event handler?!
