Dim file As System.IO.File Dim reader as System.IO.StreamReader Dim line As String
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 am using Visual Basic 2008 Express Edition, my goal is to read an entire .txt file that works as a template and replace all ocurances of a word with a new one and save this new modified text in a new .txt when you press a command button.
I finally figured out how to open a file ..find the text that I need to change and then change the text to whatever I put in a textbox then save the file into a separate folder.....my issue now is can I upscale the process to can I patch all the files within a folder to change the text in all of them to the text inputted from the textbox all at once and then save them all into another folder?
Im trying to replace text in a file but i play it, it doesnt replace the text. I even have the spaces correct but it doesnt want to replace it with nothing.
Dim EntireFile As String Dim oRead As System.IO.StreamReader oRead = IO.File.OpenText(TextBox1.Text)
I have been working on a project in .net. I can now write to a txt file using [code]What I need to do though is instead of writing new lines to the file is replace what is all ready there with new text.
I have a project to complete and i have begun the code. What i want to do is go through the text file and find evey | (pipe) symbol and change it to a , (comma). I have the code and worked out how to do it but the code will only work for the first line. I was just wondering whether any of you had any advice on the way through this problem because i am stumped.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As_ System.EventArgs) Handles Button1.Click Dim strFile As String
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 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()
Is this writing it back to the file also....I think that might be the problem, not sure..
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")
I need to open some HTML file, then replace exact line of text with another, and then WITHOUT SAVING THE FILE (WriteAllLines(HTML01, lines)) to display in WebBrowser. My code in private sub of replacing the line is next:
I am very new to VB.NET, I want to create a Forms Application to load a text file that has lets say 50 lines, some of the lines are identical and those are grouped together and some same format but different make up. Have it loads it into a text box in the form, to see - but I want another button to randomize all the lines and then show that in the box, and then have a Save button to overwrite the orginal.
I would like to step through each *.txt file in a given directory, open it, find and replace all, perhaps a thousand, occurances of a given string (e.g. "00/00/00"), then close and save file, and step to next one in the directory to do the same find and replace. I've been looking at filestream classes and regular expressions but don't see a clear way to do this.
Been trying to get somewhere with this in another thread, but no such look, just keep getting reffered back to the same documentation... If I understood the documentation, I would have fixed it by now:

I have thios code that will load a php file (text file) into a sting via streamreader then its supposed to find and replace a portion of the text and write the changes back out to the file via streamwriter. I put my code together and after running it look at the file and it's unchanged. After looking closer it appears the problem is the find & replace operation I am doing on the string. Here is my code:
This code is working fine, but now I want to replace two times and I want to use the replace function twice. Something like this, but it is not working . Can anyone tell me how to use Replace function multiple times?
