VS 2010 - Append New Line To Text File

Aug 28, 2011

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()

Append Text To Each Line In An Array?

Jan 1, 2011

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

Append And Save Text To File?

Jul 15, 2011

This question is a little more in depth than the typical append and save. I'm needing to append multiple controls text to 1 file. Basically what I have is:User inputs name in TextBox1 User inputs Service Type from selected list in ComboBox1 User checks of any or all CheckedListBox fields that apply. 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. For every checked item in a checked list box, I would like to writ

Append A Text File With Items From A Listbox?

Oct 14, 2009

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.

Private Sub Button8_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button8.Click
Dim save As New SaveFileDialog
save.ShowDialog()
Dim saveFile As String = save.FileName

FCL For A Method That Will Allow To Erase A Line Of Text From A Text File And Replace It With Another Line Of Text

Dec 19, 2008

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.

Reading Text File Line By Line, With Resetting Position To Beginning Of File

Jun 23, 2011

I'm reading a text file with StreamReader, line by line. If a condition is met, then I do an operation and then start reading the file again from the first line. I realize I could close and then re-open the file, but surely this would be very slow.

I could do this easily in VB6, but pulling my hair out trying to do this in vB.net. It seems that 'Seek' is the function to use, but it doesn't work.

I've seen other examples, where it works, but you must open it a different way -- with a file number.

Search A Text File Line By Line - VB08

Apr 8, 2010

I just joined this forum as I've been looking for a nice and serious VB forum for a long time

I'm having troubles making a program to search a text file line by line for a specific string.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim objReader As New System.IO.StreamReader("C: est.txt")

[Code]...

as you can see in the code its supposed to read a text file and if the line contains the same string as in the textbox then its gonna make a messagebox.

now the problem, if the line does not contain the specific string but the next or any line other line does, then it should automatically read the next line on "Else" and that's where I'm lost

for a "Readnextline" command or something like that?
