I'm attempting to get an arraylist to display in a Listbox (listbox2). The
arraylist is created from selections in a different listbox (listbox1). The
1st listbox has a selection mode of MultiExtended. Once the selection has
been made in the 1st ListBox, the user clicks on a button to generate the
arraylist using the values selected. Then click a second button to display
the arraylist contents to ListBox2. There are no errors, but all I get...

Here is an odd issue. I am trying to shed some light on why this is causing
a problem.
I have an ArrayList. I am binding it to a ListBox control with has its Sort
property set to True. If the ArrayList only has one element in it everything
works ok. But as soon as I have more than one element, I get the following
exception when the control loads up: "Cannot modify the Items collection
when the DataSource property is set.".

Hello
I am trying read from a xml file, pull the values in a object and then add
the object to an ArrayList.
I am using a 'while' loop to move through each node in the xml file and
pulling the required values as needed and setting them to the relevant
property within my object. The reading of the xml file works as it should.
I get a problem when I try to add the object that I created to the
arraylist. It seems to be adding each one,...

My problem occurs when I use an ArrayList as a ListBox.DataSource. When the
ArrayList attached to the Listbox is not empty the Listbox behave normal
without problem, but if I remove all items from the ArrayList and re-attach
the ArrayList to the ListBox the program hangs for about 3-5 seconds then
keep running normal.
I'm following the examples from the MSDN and dont see anything abnormal.
This is a sample of the code I'm using:

I am creating a "from-to" set of listboxes where the "left" listbox had a
list of values and I want to be able to select these values, 1 at a time,
and move them into a "right" listbox, removing the selected value from the
left listbox. When you select any member from the left listbox and click on
the button to move it to the right listbox, everything works fine. If you
select the LAST member in the left listbox, and click on the button...

Hi all,
I have a listbox that is complex bound by an arraylist. The problem is that
when I delete an object from the arraylist, the listbox does not reflect
those changes. I tried refreshing the listbox with no luck and, because it
is already bound, I can't just delete the item directly from the listbox
without an error (because it already has a datasource, you are not allowed
to delete/add anything to the listbox directly).
The...

Basically I have a listbox to which I add simple STRING items- I have a
progress bar which I increment whenever I populate another portion of the
complete set of items I wish to add. What I observe is that as more and more
are added, population of the list box takes longer and longer. ie the first
10th of the item set are added much much quicker than the last 10th. THis
occurs with about 40,000 listbox items. My worry is the listbox may...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
