I know the above is wrong, but it was an attempt.
add all of the items of an enumeration into a an array of strings....
1
Enum Test
apple = 0
plum = 1
[code]....
If possible I'd like to dynamically at the start of my code be able to add apple, plum, carrot and scotch to the contents of an array (really a combobox) and if I have to had another item to the Enum that it automatically be added to the array.I seem to keep having to add vendor names (replacing produce/liquor) and I need the items to show up in a large project in many places and it's a pain to have to add the item to each every time.
I have an array list declared globally as
Dim OnGraph as new ArrayList
I also get these two debug error.
I'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?
i have a listview box full of items, image below:
when i click a button i would like a msgbox to pop up displaying how many are alive.
How would i do this ?
Also how would i remove all items that status is "Dead"
Imports System.Collections.GenericI
mports System.Net
Imports System.IO
Public Class Form2
'Dim filename As String
Public ftpSettings As FtpClient
[Code]...
I don't know what's wrong, i can only move the 1st item but the second and so on doesn't make any changes. It remains in a listbox.
So I want it to remove any text in the list box that has a "Job" in it and just replace it with a blank nothing.
Like if the listbox looked like this
Yardjob
jobsong
redjob
then it would change it to this
Yard
song
red
I also would like a way of removing any blank items from the listbox.

My problem is that I have the same code for all three listboxes to remove "" from the listboxes except one listbox will not remove the items. I've tried countless times to remove the empty items and failed. So how do you see if a listbox's item contains no text?
