Forms :: Make A ListBox With The Addition Of Each Item?
Apr 24, 2011
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.
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).
Im trying to remove a certain bit of text from my listbox item..
heres my code..
If ListBox1.Text.Contains(".zip") Then ListBox1.Text = ListBox1.Text.Remove(".zip") End If
and when i start it and it tries to remove it, it comes up with an error saying
Conversion from string ".zip" to type 'Integer' is not valid. ive tried, this code.. If ListBox1.Text.Contains(".zip") Then ListBox1.Text.Remove(".zip") End If
how can i automatically update my value when a user changs the listbox item. At the moment i have a button click when the user changes the list box item and press the button the values get updated, everytime the listbox item get changed i have to repeat it click the button to update the value. I want something where automitically as soon as the listbox item selected the total value in the text box to change without clicking the button:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click If ComboBox1.SelectedItem = "Seafood" Then TextBox1.Text = 3.5 * ComboBox2.SelectedItem

I tried to add icons to the items in the listbox(owner drawn listbox- variable). I m able to do it. But after adding the items, according to my requirement i need to remove few items now and then.I used:Listbox1.Items.Remove("Aqua")This removes the last item from the listbox instead of the mentioned one. the same is done even if i try to remove the selected index item.
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 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 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.
i am new to dot net and i have a problem with this code below. what is expected is that the method should add the names in the string in random order into the listbox. but the output shows only single alphabets added rather than the whole name. i don't know where im wrong.can anyone correct me?

How someone would select an item from a list box and click a button and have that item go into another listbox with it's price? I seem to be stuck on this part.
Here's my code:
I want to select the first option from the first listbox and I want to put it into another listbox along with the price of that item on the same line in the listbox. I can't seem to figure out how to that.

removing Listbox item from checked Listview item.The code I tried just errors out.

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?

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.
