VS 2010 Button Not Reading Listbox?

Nov 29, 2011

I figured a fix using if statements which lets me click the button without issues, except just 1; it doesn't read from the listbox. here's the code i'm working with

Private Sub Button5_Click(sender As System.Object, e As System.EventArgs) Handles Button5.Click
Dim a As New Random

[Code]....

I need it to be able to read from the listbox while it is closed, instead it just thinks that nothing is in the listbox, but when the form with the listbox is open, it reads from it perfectly, what shall I do?

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

VS 2010 Getting A Button To Read From Xml File Or Listbox?

Nov 29, 2011

I'm trying to get a random line of text to appear in a messagebox upon button click, I want the listbox to be closed while the action is to be performed.

I can do it when the listbox is open but not when closed, here is what happens if I try to do it when it's closed

and the message "InvalidArgument=Value of '0' is not valid for 'SelectedIndex'."
I tried reading it straight from the .xml file the data is stored on, but that didn't go so well either.

Web Browser History - Clear The Listbox When The Form Closes

Feb 26, 2010

I have a small script that logs all of the website I visit and then displays them on a form. When I open the form the first time it displays all of the websites like it should. However, the second time I open it, it displays two of every website. The third time opening it, three of every website. I think that it is because the data doesn't get erased from the listbox when I close the form. Is there a way to clear the listbox when the form closes or do I need to find a new way to set it up?

Listbox Items Colour - Two Types Of Items Populating In A Listbox (checked Listbox)

Apr 28, 2009

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.

Interface And Graphics :: Listbox Event - Scrollbar That Comes With ListBox Is Too Small For Touch Screens

Jan 6, 2011

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.

[2008] Copying From One Listbox To Another And Keeping The Paths Of The Files In The Listbox's

Jan 26, 2009

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.

[CODE]...................

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.
