I am trying to append a new line to a text file. Sometimes it posts to a new line (like I want it to) and sometimes it appends to the current line, consequently screwing up my read. I even put VbNewLine in the code.
Here is the snippet:
Dim outputline2 As String
outputline2 = equip & "," & value
Dim myfile2 = File.AppendText("equiped.txt")
myfile2.WriteLine(outputline2, vbNewLine)
myfile2.Close()
[URL]
[code]...
When I run this I get the file is currently in use.
Below is the code which I am using to append data to a text file.
Dim FILE_NAME As String = "C:cebsample.txt"
Dim objWriter As New System.IO.StreamWriter(FILE_NAME, True)
Dim record As String
Dim amount As Integer
Dim amt As Decimal
[Code] ....
Now I would like to save that updated file with another name.
how can i append the text in rich text box say i need to append in line 40 and column 30
View 1 RepliesI have a button that append a sentence with some strings in it to a richtextbox. Everytime I click the button it appends a new line and then appends the text again till i eventually hit the bottom and beyond of my richtextbox. how to add my line as LINE 1 in my richtextbox and moving the earlier appended text down.
rtbHistory.AppendText("Round : " & lblRound.Text & " / Dealer : " & lblDealer.Text & " / " & lblBidder.Text & " Bid " & cbBid.SelectedItem & " In " & cbTrump.Text & vbNewLine)
Say I've got a variable that contains multiple words, each one separated by a newline. What I'm trying to do is add specific text to the end of each line in that variable.
For example, say the variable contains...
alpha
bravo
charlie
etc
etc.
And say the text I want to append is "newtext"
So then I'd like the output to look like...
alpha newtext
bravo newtext
charlie newtext
etc
etc
What I tried to do is to split that variable into an array (separated by newline), and then use a For Each to append the newtext to each line in the array. But it's obvious I haven't messed around with VB in a long time, as something is wrong with my logic. Here's what I've got...
Dim Text_Array() As String
Dim OriginalText As String
Dim OutputText As String

I'm trying to have a program remove lines from a text file if they start with a certain string. I haven't had much luck with this over the past couple of days so I thought I'd try and get some advice.

I am reading a list of IP's from a text file. After every procedure, the first IP (the first line) needs to be removed, and the new first IP will be read at the beginning of the next procedure. Basically, I just need to know how to get rid of the first line of a text file completely. For example, I'd like to go from this:
1.1.1.1:80
2.2.2.2:80
3.3.3.3:80

Now, all together, there are actually between 4 to 6 different checkedlistboxes.What I am wanting to do is when the user clicks the Submit button (Button1), at the bottom, it will write a text file of TextBox1.Text,omboBox1.SelectedItem.ToString, and all the checkedlistbox items.Now there is a small thing I may have to start another question on.

View 1 RepliesOkay, so I've been looking on the web for a way to read only ONE line out of a text file. Recently I've gotten by by creating separate text file for each line (such as a text file named, "Username", another named "Password", instead of creating a single text file with both the user name and password.) Now I am faced with having to do this. I want a quick and easy way, VB won't let me do open file as input #1 for some reason. I just need the second line of text out of this text file. What is the quickest and easiest (and painless) way of doing this?
View 8 RepliesI'm trying to remove a line from a text file that begins with a set value.
The idea would be to paste values into a Windows form, which then finds each line that begins with that value (a 5 digit number) and removes those lines from the file, and then removes the gaps.

I want to append a text file with items from a listbox. I tried to search for a code to do that, but couldn't find anything(most likely I don't know what I am looking for). But I wrote this code and got it to work, but after looking at the code, it looks sloppy and I'm sure could have bugs I didn't catch....my question is, is there a better code than the one I made, or will my code work fine. I am eager to write code correctly, not just get the code to work.

i'm writing an application where error messages are written into a text file.
text file is created using win32API createfile() function.
after that everytime an error occurs the message is written into the text file with writefile() API.
but whenever a new message is written the old text in the file is getting overwritten.
i want to append the new message at the end of the text already in the file.
I'm new here, but have been in and out for a while. Past threads have been helping me along thus far.
I'm currently developing an app which essentially needs a way for me to search in a text box or file for a specific string, and extract the line on which that string appears on. It will be unique, and the syntax is the same on each line. It has basically 2 ID numbers, and is laid out like this:
123456|123456
So, I'd need to search for the first part before the |, and then get the line so I can get the bit after the |, which is the important bit for me.

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

However, I can't find any methods that will allow me to do this.

So I'm sending text with the program launchy this .vbs (addln.vbs) - ("$$" c:ideas.txt) is what the argument is if I want to send to ideas.txt for example All I want to do is make it so I get the date and time right before whatever text I send to this text file. I don't think this would be too complicated.
