Append And Save Text To File?

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

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)

Append Text To A Textbox VB?

Jul 12, 2011

I am attempting to append information to a textbox in VB. My app allows the user to choose a variety of options and displays all the information in a single, read-only text box.

I would like to set it up so every time an event triggers something to be written in the text box, it gets appended instead of overwriting the text currently in the box.

The only constraint is that text should be appended as a new line, not directly after the last sentence.

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
