Apr 15, 2009In .NET there doesn't seem to be a property to find the item just selected in a multi-select listbox; SelectedIndex always shows the first selected item. From memory VB6 had the ListIndex property that changed accordingly... Why remove a useful property ?

Reload Multiselect Listbox Controls?
Oct 4, 2010I have a multiselect list box on a Windows form (VS 2008) containing references to 35 different work stations.

VS 2010 ListView MultiSelect Rows With Mouse Drag - Win7?
Apr 23, 2012In WinXP with LV FullRowSelect enabled I can press and hold down the left mouse button and drag it down the right side of the left-most LV column and the rows are selected, but under Win7 I can only multiselect items with the mouse if FullRowSelect is set to false.
So I guess I need to write code to support this sort of feature for Win7 ? , and if true are there any code examples (I can't find anything) to save me some time?

Check Proxy's From Listbox?
Jun 8, 2011So i have a listbox that i have there for a list of proxies. I have 4 buttons pertaining to it. they are find, load, save and check
I have the first 3 finished and working but i haven't found anything useful pertaining to checking the proxies, the only one that i found took like 6 seconds per proxy so it took a lot of time for a decent sized list.
So how could i make it that on the press of that button, it checks all of the proxies in the listbox and it deletes the slow ones and the ones that flat out do not work. and does this at a decent pace(so it would probably be multi threaded)
and since i can not figure this out i have no code pertaining to this except for the sub for the button click i do not feel there is a need to post code

Check Number Of Items In Listbox?
Jan 17, 2009I have a listbox, textbox, and a button. every time I push the button, an item from the listbox is put into the textbox. when the button is pushed again, it grabs the next item in order and puts it into the textbox. so on and so on until it gets to the last item. once I get to the last item it keeps repeating the last item over and over again. SO what I was wondering is how do I get a messagebox or some sort of checker to tell me when it has moved the last item from my listbox to the textbox?? PS textbox2.text=0 and every time the button is pushed another number is added to the value of textbox2.text. so basically if I could figure out how to grab the value of lines at any given time in listbox I could call a msgbox up!! here is the code I am currently using[code]...

View 4 RepliesListBox PreferredHeight - Make ListBox Calculate Correct Integral Height Before ListBox Is Made Visible
Nov 19, 2009If I set a ListBox.Height = ListBox.PreferredHeight when the control is hidden and IntegralHeight = True, then set it visible:
a) Actual Height reduces by typically 3-5 pixels after redraw (but not 1 pixel per item).
b) PreferredHeight does not not appear to give the correct integral of item heights.
Is there a way to make ListBox calculate the correct integral Height before the ListBox is made visible, so it can be correctly pre-positioned from bottom edge?
