How do i make a ListBox with the addition of each item, the item be removed after 4 seconds? Added time and number of items is unknown. Other parts of the job application should not be hampered. I know that thread should I use, but I do not know.
View 2 RepliesI 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).

View 3 RepliesI 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 am designing a degree audit program for school, and have a listbox where all the classes needed are contained. I have a separate form for each year (Freshman, sophomore, etc.), which also contain listboxes which are empty. The idea is to add the selected class from the first listbox into the empty listbox in the appropriate year form. However, to do this I would like to have the same listbox (the first one with all the classes) appear on each form, but still reflect changes made to it from other listboxes (classes transferred out of it).
To do this, would I need to create a listbox with global properties? Or would it be better to create a global function containing all the classes and have its contents called to the appropriate listbox?
i have this..
ListBox4.SelectedIndex = 0

I have a list box on the form which functions as a copy/paste. When you copy something, it is automatically added to the list box as a "clipboard helper". Here is the problem,however: if the text is more than 1 line, the list box does not show all the text.It ends up looking messy.So getting back to my question, is it possible to make the list box item height for an item depending on the amount of lines that item contains?This is a one line sentence in the list box and should take up one line.This is a multi line sentence in the list box and should take up two lines for item height.

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
