ListBox 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?
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
ListBox1.Visible = False
ListBox1.IntegralHeight = True

If What You Typed Is Not In The Listbox Collection Than Error Message
Oct 14, 2009I cannot find how to display an error message when what I typed in the listbox field is not in the listbox collection.
For example the listbox contains the following items
1) Apple
2) Strawberry
3) Mango
If for example I type "Mongo" and then press tab to another field, a message will pop up saying I typed something not in the listbox. Anyone who knows how to code if text in textbox1 is not in listbox then blah blah blah.

VS 2008 ListBox.SelectedValue Causing Error
Mar 25, 2010When my form is loading, it executes a Method called populateListBox().As the ListBox is populated, it inevitably triggers ListBox.SelectedIndexChanged, which triggers this
Private Sub lstLabels_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstLabels.SelectedIndexChanged
Try
buttonCheck()
Dim pathText As String
[Code]...
If I stick the Try...Catch in, allowing it to bypass the error, everything loads fine and when I double click an item in the ListBox, I have a MessageBox setup to show the SelectedValue, and it works fine (it shows a number like it should). Even if I put a MessageBox in the SelectedIndexChanged event, I still get the same error on the MessageBox line during the loading of the form.
Is this because the form is not fully loaded that I get this error? And what would be the proper way to handle this? I need this code in the SelectedIndexChanged for when the user selects a new item, so how do I keep this error from happening (or maybe even the event from triggering) during form load? Because I'm sure having a Try...Catch is not really an accepted form of "fixing" an exception; it's just ignoring it.

VS 2010 Adding Error Message To Listbox?

I'm not sure where to input it or if my avenue of using the If..Then statement is even on track. Here is the code I have:
