ListBox PreferredHeight - Make ListBox Calculate Correct Integral Height Before ListBox Is Made Visible
Nov 19, 2009
If 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?
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
ListBox1.Visible = False
ListBox1.IntegralHeight = True

I am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.

I'm using a list box control and I've specified an item height of 25 and DrawMode of OwnerDrawFixed as well as coded up all the necessary ListBox_DrawItem code to get this to work. My problem is when it displays my list all the items are top justified in the list. I want them to be centered and right justified so when the are selected they are in the center of the highlighted box, not at the top of it. Does anyone know how to do this?

I am a new student of Visual Basic. I am using Vis. Studio 2010. Is there some sample VB code that I can gain access to that shows how to test on multiple selections that were selected within a listbox using the "For each" construct? In this scenario, multiple items have been selected but not 100% of them. I need to know how to test on which ones are selected as I examine each one in the list using the "For each" construct.

The scrollbar that comes with the ListBox is too small for touch screens, so I use my own scrollbar instead. But when you do this on various forms you end up repeating a lot of code. So my solution was to create a custom scollbar that has a property I can set to the control I want it to be a scrollbar for. In vb6, I can use the withevents keyword to get access to the control's events so that all the scrollbar related code can be in the custom scrollbar object I created, except...I had to create a refresh method for the consuming code to use to let the scrollbar know when the number of items changes. The scrollbar doesn't need to be told how many items there are because it has access to the control, but for a listbox there is no event to tie into when an item is added/removed so not 100% of the scrollbar related code could be encapsulated.

Is it possible to select an item in one listbox and then display the data of another listbox with the same indexed position? I am planning a project and this is something I would like to attempt but I haven't figured out how to do it.[code..]
I tried doing the above code but instead of displaying the listbox text the message box just returned false.

I am using Visual Basic 2008 Express Edition and I am trying to set a listbox so it starts to scroll when it hits the middle point of what is viewable on my list. I also want to set it so the list is always visible so you when you reach the bottom of the list you can scroll down to the bottom but if you scroll back up once it reaches that middle point it will start to scroll up again.

I'm curently trying to get information displayed in a listbox from a selection made in a datagridview. For example a user selects an artist from the treeview control and it displays all the albums by that artist in the datagridview. Once a user selects an album all information for that album is displayed below the datagridview in either a listbox or listview control. I've tried dragging the conrols from the datasource and it' won't drag onto the listbox. What do I need to do to get it so that it will display album, artist and track information?

I am having problems with copying from one listbox to another and keeping the paths of the files in the listbox's. At the moment i have two listbox's, listbox1 shows the list of files without the directory paths showing. Listbox2 is used to add items from listbox1 which work ok but what i need is to be able to preserve the directory paths to each file. how to do this and have searched high and low for a solution without any luck.
I have worked out one way of doing it but i think there is a better way of doing it as the reverse does not seem to work. So basicly i want listbox1 to list the files without the paths and pass it on to listbox2 so that the files can be copied to temp directory as they are being add to listbox2.
Below is my
[CODE]...................
Routine to add items from listbox1 to listbox2: I have created another listbox3 (which is in bold), which is hidded under listbox1 and holds all the paths to the files and is use to copy the files from there original directory to a new directory.

Routine to add items back to listbox1 and remove them from listbox2. I have created another listbox4 which is hidden under listbox2 which i was trying add the paths from listbox3.

I have a listbox which on form load generates correctly from a text file like so in a listbox...ex"John Doe, 1""Bob Brown,2"I now would like to search the listbox if it contains either a "1" or a "2" which is does in this case and copy the item to another listbox. The 1 and 2 indicate positions I have a position listbox for each position. So 3 listbos, first one contains the names on form load, 2 other empty listboxes one for position 1 other for position 2...I have tried the following
If xReservationListBox.SelectedIndex = xReservationListBox.FindString("1") Then
'MessageBox.Show("Found It")
xSpot1ListBox.Items.Add(xReservationListBox.Items(0))

I have 2 listboxes on my form.Listbox 1 - populated with "available" field namesListbox 2 - populated with "selected" field names.There cannot be the same field name in both listboxes - it's either one of the other.The logic I was going to apply was to populate Listbox 1 with every field name ... and then as I populated Listbox with the field names which the user has already selected, remove the corresponding item from Listbox 1.

I have a program that lists all the countries in the world into one listbox, and all the cities in the world in a second listbox. What I want to do is make the program so that all the cities of the country are listed in the second listbox. So what I did was I made two 2 dimensional Array strings. Then made an algorithm to link the first listbox (country) to the second listbox Cities.
[Code]...
when the program begins it lists all 192 countries. when you click on the country it is should list all the cities in the country inside the second listbox...
