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.

First it might sound like an ordinary task but keep reading it isn't. I can't figure out how to find a phrase in a text file, and replace it with something else. Tried lots of things but always ending up with empty hands.
Suppose there's a text file in this order:
valueabc=6000.0000
valuettt=200.0000
valuexyz=7000.0000
I want to;
1) Find the phrase (e.g. valueabc) by scanning the whole text,
2) Replace the number that starts after "=" and ends before ".", namely "6000" in the middle with any number value i want.
I don't need the parts before "=" and after ".", only the number in the middle.

View 1 RepliesI am wondering how I can go about replacing certain words in a rich text box with different ones.
Say I have 2 textboxes a button and a rich text box.
I want to have Text1 as the box where I would enter the word being replaced.
Text2 would the the box with the word I am replacing it with.
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")

View 1 RepliesI 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?

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.

View 4 RepliesI 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).

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.

I have a program that will read a text file and put information from the text file into multiple text boxes. What I am trying to do now is be able to change the values in the textboxes and be able to write the specifc changes back to the text file. One way I though of doing that was using a while loop and copy the lines of the text file to another text file, then when it finds the line that has the specific change from the text box, make the change and continue writing the line until it reaches the end of the file. Then I was going to copy the file and overwrite the original, escientally making the change to the new file. Right now it will make the new file but will just make a blank text file. I think the problem is in the while loop statement but I am not sure. Here is the code below:

I have to find a string in a huge text file ( ~ 50MB) and then replace it.Since it's quite huge I tend to open the file and then read line by line, and then replace the necessary line(s) (rather than "readall" the file of course).My question is how to replace the whole line?Let's say I found the line that should be replaced . I know I can create a copy file and copy all lines into there ... but I'd prefer to replace the line in the original file rather than creating a copy instance.
