Make Search And Text File And Replace It?
Sep 3, 2009
I got some code that im try to make search and text file and replace it. The code im using to replace it with is whatever the user entered in txtURL.text. Here is what i have
Dim strFile as String
Dim result as String
strFile = "C:\test.txt"
oRead = IO.File.OpenText(strFile)
result = Replace(oRead.ReadToEnd(), txtURL.text, "1F.php")
oRead.Close()

I have a 133 Mb file which contains almost a million records. Currently, a user loads this file into KEdit (a great editor for working with large files) and changes occurrences of a dollar sign $ to blank and takes negative numbers represented as such with parentheses and changes that to a negative sign. That is, (5000.23) would become -5000.23. So the leading ( becomes a - and the trailing ) becomes a blank. I believe the only occurrences of ( and ) are around the numbers I want to change, so I don't have to worry about changing something that should have been left alone. Using VB.NET in Visual Studio 2008, is there a "painless" way to do this other than reading the file one record at a time and searching/replacing and writing the record out? While not really painful, I am worried about how long that will take (to run, not to code ). Is that a valid concern?
My long range goal is to automate many of the routine file preparation tasks my users do. We get an input file from 15 clients. The file can be in any format the client has chosen to give us, and it is our burden to reformat any errant fields into an acceptable format for insertion into our database.

I've figured out a way to load a php file and then search and replace if it contains one of the following:[code]Is their a way where I can load the the php file and also load a txt which contains the string i want to replace, so the exe dont actually save the txt.Replace. This way the user of the app can define the contents of the search and replace and it wont run out of memory.

I am needing to open up a file, it is a kml file, and I am wanting to search for a particular line and the replace some of the lines following that.
Dim file As New System.IO.FileStream(kmlFileName, FileMode.Open, FileAccess.ReadWrite)But I don't see any means in which to actually go through the file line by line in order to search for my criteria.

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.

I was wondering how I would go about replacing a specific line of text with different text, and then later reading a specific line of text (from the same file). The text file has a lot of lines, and basically the layout is like this:
Something1 Data I want to read
Something2 Data I want to read
Something3 Data I want to read
Each line has a specific word, and then after that word is the data I want to use for the form.

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:
Code:
Private Sub submitButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles submitButton.Click
Dim trackname As String

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.

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")
