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

Save Items In A Listbox To A Text File?

May 27, 2009

I've been trying to figure out how to do this correctly for some time now, and I have seen no insight. I'm trying to successfully save all of the items in a listbox without saving items that are not there. What I mean by saving items that are not there is when it saves, it seems that blanks magically appear in the text file.Here is a sample of my current code to save.

[Code]...

I'm not completely sure if it's the loading or the saving that's causing problems, but what would happen is it would add a blank item to the listbox that I do not want.Here's a picture before the listbox is saved, look to the bottom left.Now here is what it looks like after: (notice the red oval)Does any one have any idea what could be wrong?If you want me to attach the text file, just ask.

Write Listbox Text To Text File And Keep Columns Aligned?

Apr 16, 2011

I've got a program which displays data in a listbox in five columns. All are separated using one or more ControlChars.Tab. I want to write these columns to a text file, however, when I do, my columns lose their alignment. I can change alignment so that it displays nicely in text file, but then it is off in list box. Is there a way to get what I see in my listbox to display the same way in a text file - maybe a different way of separating my columns (not using ControlChars.Tab)?

File I/O And Registry :: Using The SaveFileDialog To Save Listbox Info Into A Text File?

Mar 17, 2010

I'm using the SaveFileDialog to save listbox info into a text file. The files save fine, but when you go to save the file, if you hit the cancel button, it will overwrite the previous file you saved, because it's name was the same and it seems to save the previous file as the new name for your next file. Is there any way to catch if the user clicks cancel, and then exiting the sub if they did?

Reading Text From A Text File Into A Listbox

Dec 15, 2010

I'm a little new to VB, and I'm in a class for it, but I'm trying to do something we aren't going to learn in the class (mostly out of sheer interest) and I need help. I'm trying to read lines from a text file into a listbox, each line representing a new item on the listbox. For example, if the text file reads: [code]I want to be able to take that as is and read it into a listbox, where those words would appear in the exact same fashion; as a list, each as separate items. I've looked at the Help stuff and learned (sorta) about delimiters... but the thing is I don't want to write my entire list in a continuous line separated by commas--I want it to keep reading each line, and moving on to the next, until there are no more lines left. I am thoroughly stumped, and would appreciate it SO much if someone could help. For a frame of reference, this is the point I'm at now with my code: [code]Note that when I run the program, all it will do is read the first line of text available and stop; once I press ENTER in a text file, it decides to stop reading.

ListBox And Text File Manipulation?

Oct 10, 2010

The homework assignment goes like this: write a menu-driven program to manage an employee list. the names should appear in the listBox when the form is loaded. When a name in the listBox is highlighted the name and number txtBoxes are loaded with the correct name and employee number. Use the Update menu items--modify,add,delete to edit the listBox items.When the Exit menu item is clicked the new employee list should be written to the text file and the program should terminate.

Well, the first part was completed successfully, but when I tried to delete a name and number I recieved an error box that said "InvalidOperationException was unhandled", "sequence contains no elements" that pointed to line 35. msdn and help were no help, talked about dataset tables? Did I use the incorrect syntax? Once I resolve this issue, the other two--modify,add should be similar, but then how do I reconstruct the text file so that it will properly load the next time the form is loaded?

Loading Text File Into Listbox?

Feb 5, 2009

So i have a text file that is created in the program which can be loaded back into the program(game save)

Whatever is in the text file "stats" should be listed in listbox1 in the same order it is in the text file. The same with "items" in listbox2. And then "quests" will be in listbox3.

The problem is when i load it instead of what is in the text file it says...
