System.IO Directory

Hi

I'm new to vb.net and i just read up on system.io namespace, directory. my mind just generated an idea on creating a application that 'Create', 'Delete', 'Refresh' Directories. but currently my listbox1 is giving me errors...
Argument not specified for parameter 'item' of 'public function....

i inserted the following code into a button/form both generated the same error message.


Dim str() As String, intx As Integer
str = Directory.GetLogicalDrives
For intx = 1 To UBound(str)
ListBox1.Items.Add = str(intx)
Next


thanks in advance. :p

TRY THIS:

Dim str As String(), intx As Integer, i As Integer
str = Directory.GetLogicalDrives
intx = Directory.GetLogicalDrives.Length - 1
For i = 0 To intx
ListBox1.Items.Add(str(i))
Next

you dont need to loop through the drive letters though :) in one easy line ...

ListBox1.Items.AddRange(IO.Directory.GetLogicalDrives)
'/// add the array of drive letters in one go.

Thanks!
can i know why it doesn't work?

i had a friend who prefers using UBound(Arry) over Arry.Length - 1

but why?

THis one is really nifty...
woo!
thanks!

Since you are using .NET, use the array's .GetUpperBound() method to get the UBound instead. :)
And i.ToString() instead of the str() function, which is outdated even in Legacy VB.

Cool. Ill remember that addrange one.

a reply to the above...
How do i use Str() Function in the following code?

Dim str As String(), intx As Integer, i As Integer
str = Directory.GetLogicalDrives
intx = Directory.GetLogicalDrives.Length - 1
For i = 0 To intx
ListBox1.Items.Add(str(i))
Next

i tried changing to
ListBox1.Items.Add(i.ToString(str))

but it does not work

firstly you shouldnt declare a string with the name Str , as Str is a function.
if you wish to add each item through a loop, do either of these ...

Dim drives As String() = IO.Directory.GetLogicalDrives
Dim x As Integer

For x = drives.GetLowerBound(0) To drives.GetUpperBound(0)
ListBox1.Items.Add(drives(x))
Next

or ..

Dim drives As String() = IO.Directory.GetLogicalDrives
Dim drive As String
For Each drive In drives
ListBox1.Items.Add(drive)
Next
