Hi All
I have a databound ComboBox control which is put into the second page
of a tab control. When the form loads up, I databind the combo control
and populate the control.
When I go to change the tab page to the second page, the application
hangs...becoming completely non-responsive.
If I populate the combo control with no databinding, I can change to

Using .Net framework 1.1
I've got a Windows Forms application with a tab control having four tab pages. TabPage4 contains a Combobox and a TextBox, which are bound to the same XML file as a DataSource. The ComboBox displays the values from the "name" column of the DataSource and the TextBox displays the "location" value. The two controls are co-ordinated by a BindingManagerBase (bmInfo). When a different "name" item in the ComboBox is...

I fill a table in a dataset with values that will be used by a combobox
for the combobox's items. The combobox is a drop down list that only
allows the user to select from the list but not enter any new values.
What I need to do is include a blank row in the list so that when it is
selected, the SelectedValue property returns a Null. I don't want to
add a record in the database with some field set to null because this
would have to be...

I've got a databound combo (databound to a System.Data.DataTable), but some
rather unpredicatable behaviour -- even though I have 8 rows in the source
table, only the first 6 are showing up in the items collection.
I've been scratching my head over this for a while now, but can't fathom
what could be to blame for this oddity.
Has anyone seen this behaviour before, or can think of any possible causes?

I posted this in dotnet.languages.vb.controls but thought I'd post here as
well..
I have a combobox that is bound to a dataview generated from a dataset.
The dataset has a single table (called "Data") with two columns "Id" and
"Description". Id contains a code and description contains the
description that is displayed in the combobox.

I've been reading all the help I can on the topic (MSDN, other) but I
can't make sense of this.
Desired behavior;
The user is to choose from the displayed list of the databound combobox
and the coresponding 'Id' from the lookup table is to be inserted into
the field of the new record.
I have two simple tables. "tblPerson" is the data table. The lookup

I have a combobox that is very much like the one found in the RSS
project here:
http://msdn.microsoft.com/vstudio/express/visualCSharp/learning/
My projectNameComboBox basically is filled with a list of values from a
table, and as the user selects values, a datagrid displays related
records from another table because it is bound via FK relationship.
My table:

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
