Looking for unique term 'END' in file - want to delete the term as I will append text later in the routine and append a the same unique term 'END' later in the same routine. Here another poster's code to find the term:
Dim file As System.IO.File
Dim reader as System.IO.StreamReader
Dim line As String
I have a program with the connection string to my database in the config , this file is in the main directory where the software is installed. My question is: Other people can edit or replace this config file with other for example to connect my program to his database? or edit other settings in the config ? so my program will work with a edited or replaced config file?
I have is my columns are separated by spaces but these spaces can vary between 1 space and 20 spaces. So would it be possible to replace all spaces with one space? This will mean that each column is seperated by one space and I can then start working on my next bit of coding with deleting columns.
in the above text, the highlighted string are dynamic one rest all same, i want to replace the highlighted string, For example, the converted text file below.
I have two text files. The fields in each text file are separated by a space (" "). Some of the fields in column 1 of file 1 match the fields in column 1 of file 2. However the third column in file 2 is a numeric field. What I wish to do is check every field in file1 against the field in file 2, and if the number is 1 then remove the row from file 2, if the number is > 1, then subtract one from it.
I have the following coding so far.
Dim lines1 As New List(Of String)(IO.File.ReadAllLines("File1")) Dim lines2 As New List(Of String)(IO.File.ReadAllLines("File2")) Dim values As New Dictionary(Of String, Integer)()
I have a text document that stores around 200 commands ,each on its own line with a value of either 0 or 1 after them. This determins if that command is ON or OFF.
I need to be able to manipulate the on/off values for 5 specific commands using a check box to say "turn this one on" if box is marked. or vice-versa.[code]...
I am new here and just started visual basic 2008. I want to load a BIG file to edit the text. It is 24MB So whenever I load it in the richtextbox it shows : 7@ :/ Regular text files load fine. Here is the CommonDialog1Open.Filter = ("EXE [*.exe*]|*.exe|All Files [*.*]|*.*") CommonDialog1Open.ShowDialog() rt1.Text = (My.Computer.FileSystem.ReadAllText(CommonDialog1Open.FileName)) I know I am trying to load .exe! It will load if I save it through the program but will only show 7@.
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 a gridview that contains value of every rows read from a text file. What I want to do is, edit and delete the selected row on the gridview. I already have the code to show every row on the textfile:
[code]...
What I am going to ask is, how do I get the index of selected row return and fill the value to the textbox then update it to the textfile?
Ok so i have a uni assignment to delete lines of text out of a text file, so far i have figured out how to search the text file for specific bits of text, i,e name of user, ive also used a loop to find out what line in the text file the specific line exists as...my
code so far is Dim line As String Dim Input As StreamReader
[code]....
the selected policy is what im tryin to use to write over the line of texts that already exists however i think that maybe instead of deleteting what exists it will just move it down a line and make a blank line
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.
