Find / Replace Multiple Text In Rich Textbox?

Apr 12, 2012

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.

Replace Multiple Selections In Listbox With Textbox.text?

Oct 23, 2009

I have code that works to place two items in listbox into two textboxes when selected (multiple select extended).

Private Sub lstOutput_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstOutput.SelectedIndexChanged
Dim i As Integer = lstOutput.SelectedIndex

[code]....

I need also to be able to modify the data in the textboxes and replace the lines in the listbox. The reverse code doesn't work properly, it only replaces the first selected item. The "lstOutput.Items(i + 1)" appears not to lead to the second selected item.

Dim i As Integer = lstOutput.SelectedIndex
lstOutput.SelectedItem = lstOutput.Items(i + 1)
lstOutput.Items(i) = txtName.Text
lstOutput.Items(i + 1) = txtPhone.Text

I have scoured the web for ways to manipulate the selected index/indices, with no success.

Use Find/Replace To Replace Arbitrary Text Per Line?

Dec 9, 2011

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")

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?

Find And Replace In A Text File?

Jun 3, 2011

I am making a program for work, i have it partly coded, unfortunately i don't have a wifi connection for my laptop right now which makes it hard to add my code here. What i am trying to do is have the user pull in a text file from anywhere on the computer using a open file box that pops up, i got that part, to make sure that is working i have a textbox that reads the data of that text file, it gets pulled in fine using a stream reader. Now what i need to do is search the text file for certain values, and depending on the selected item in the listbox which is on another form, change that value in the text file, im guessing i will need to use a stream writer, and ive seen examples used based on the file location(C:....) but in my case im not sure how to do it.

Allows The User To Define Text In A Rich Textbox?

Sep 14, 2010

I have an application that allows the user to define text in a rich textbox. I would like to give the user the ability to define text for one or more languages. I don't think this will be a problem using the rich textbox as it allows for unicode characters and DBCS (please let me know if this is incorrect). My question is, I display this text throughout the app in other controls as well, such as a listbox, label, etc. by acquiring the RTF's Text property (plain text). Are there problems with other controls displaying unicode/DBCS characters? I realize that I may have to toggle the font of the control in question depending on the language (I will allow the user to specify a default font per language).
