I have a listbox that contains several items (the amount of items changes depending on who is using the application). The listbox is setup so the user can select more then one item. I am attempting to submit the user selection(s) to the database. The problem I'm having is that when I loop through the array to find out what is selected, I'm only getting the first item selected (because I cannot deselect it).

I have inherited from a Windows.Forms.Listbox so I could override the OnPaint and OnDrawItem methods in an effort to highlight specific items and alternate backcolors. I am also skipping some DrawItem events to prevent flickering.Everything is working fine, however when I select items in the listbox, it looks like the font is shrinking or becoming more compressed.Then when I mouse leave, the font goes back to its normal size and appearance but the same items are still selected (which is correct). During debugging the font never changes nor do any of its properties, but it does end up looking different when the item is selected and the mousedown event just happened.

i have 2 list boxes.. Qty and Cost both of these are populated from a sql database. The code is suppose to read through the listboxes and multiple the Cost by the Qty and then replace the Cost with the new result. The Cost listbox is populated with the cost of one item. The reason i am not doing this calculation in the sql query is because the sql query is very complicated filter out a bunch of stuff to show just the qty of the item...

I was wondering how do i get a value of an item in my list view to be displayed in a text box without having to select the item in the list view?
In my list box i just have one number and this number changes depending what page the user is on so it could be 1, 2 or 3. What is the vb code to actually get whatever it says in the list box and store it as a variable so i can show it in a text box? I thought it would have been something like:
Code
Dim instance As String
instance = ListBox1.Items.ToString()
txtRoomID.Text = instance
There is only 1 item in my listbox i just want to get this item and display it in a text box.
