I have a databound listbox that is causing my form to hang when I call
the show method. The list box is bound using the following code:
_dataView.Table = _data.Tables;
lboUsers.DataSource = _dataView;
lboUsers.DisplayMember = "FullName";
then when I call form.Show(), the form shows up, but hangs before it
draws any of the controls on the form. Is there any valid reason for
this? Has anyone ever seen this before? I've written the same...

I have developed a Windows Forms application with C#. On the windows
form I have a master list box with the names of people the user can
select from and when selected it calls a Select in SQL server to gather
the appropriate information. It is then populated onto a multi-tab
portion on the right of the screen. On the 3rd tab I have 2
multi-select listboxes. The problem is on the first time I go to the
tab for the first name the 2...

I have read the following article
http://www.4guysfromrolla.com/webtech/073101-1.shtml. I added the empty
selection as the first option. When I click submit without choosing
anything it does not return my empty string but the 2nd value in listbox.
When the page reloads it selects the 2nd option by default even thou my
Empty field is in the list. What do I have to do to get the empty field and
databound data to act as one?

Hi,
This is something weird I noticed recently in ASP.Net.
I have created typed dataset and I have filled the data.
when a postback happens, the data of the dataset is lost. Is there a workaround for this.
I have a databound listbox. When a postback happens the values in the listbox are still there.

Hi
I have a simple problem scenario with yet no good solution:
I want: A sorted (by name) and bindable typesafe collection (of students)
which I can set as DataSource to a ListBox. When editing a students name in
a databound textbox, the name in the listbox should update and also resort
itself (while also keeping this student in focus).

Hi all,
I am looking for a databound listbox control that can be as easily used
as the listbox control that comes with Ms Access (with as less
programming as possible). I would like this listbox to have drag and
drop capabilities, column and row format, etc. Does anybody know which
control (commercial of non commercial) is suitable for my needs?
Regards,
Gerwin Berentschot

Does anyone know how I can create a multi-column listbox in VB.Net

columns, I would be interested in looking into that as well.
Here is the code I have (it cannot display multiple columns)...

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:
