I have a ListBox built of a simple custom object for the
ListItems used to be able to hold a Data Value, and a
Display Value, with accessors for each. I have
overridden the ToString method to display the Display
value.
(Two examples that I have seen, including an MS example,
suggest that the DisplayMember and ValueMember properties
of the ListBox can be used in this way, I could not get
it to work using the ListItems.Add method -...

I am having a little trouble with the ListBox's Items collection property. I

I'm keeping this list busy! :
Okay, now I'm trying to clear a listbox
The way I have it set up, the user can either enter a value into a textbox, then hit a button, and 1 specific record is shown in the listbox. Or, the user can just hit the button (leaving the textbox blank) and all possible records are retrieved and are displayed in the listbox. These methods work great
But, when I want to switch between the two...for example, if I...

I am fairly new to VB.NET and I am having some difficulty working with a
bound listbox.
On a simple form, I open a connection to my database and load a dataser. I
then bind a listbox to the the dataset and set the display member. I also
connect some filed using databinding.
I am able to choose an item from the listbox and edit it, but the listbox is
not refreshing (only the original values are visible in the listbox). If I

I have a form with a binding navigator that draws from a database via
drag-and-drop-created controls. I'm filling a listbox with the results
of a query. The listbox contains data related to the record that the
user is viewing but cannot be databound because other events and user
input are needed when the user selects an item from the listbox.
Each time the user clicks the binding navigator to move to the next
record I have this:

I have a Listbox1 in the main form and I can add listbox1 items in the
parent form. But when I close the parent form Listbox1 in the main form does

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

For most users, this new feature is actually very convenient. If you want to control the update process,...
