Hi all,
Consider an Access 2002 run-time application on Windows XP. The controls on
a form are locked until the user clicks an Edit button. The form is based on
a query and all controls are bound.

my simple-bound object (Contact) to it's bound controls.
I'm really stuck here.
I've got a business class, e.g. Contact, that has public get() and set()
methods for it's private fields.
In my form load, im specifying the DataBindings to an instance of Contact's
properties.
I'm then, getting the Contact object to populate itself with data from
database, but once it's loaded, the databound controls are not being

I am looking for a good solution on how to implement data access in an
application so that there is a clean separation between the data access
layer, the business layer and the GUI layer. I am looking for a robust
solution for a major application. Almost every developer seems to come
up with a completely different solution. While many of them are not
bad, I really want a very good one.

I was hoping to get some opinions on the efficiency of various methods of
reusing the same dropdown list data.
Here is the situation:
Multiple panels on maintenance pages with TAB menus across the top showing
different panels. A DropDownList with a 50+ value/text entries exists on
more than one panel but only one will be displayed at a time. Examples might
be US states, countries, category codes, etc.

Hi,
I've noticed a bug in VB.NET (latest .NET Framework)...
- I have a TabControl on a form with several tabs.
- Each tab contains text boxes that are bound to fields in a data source
(DataBindings).
- When I display a record and then try to access the .Text property of one
of the text boxes on any tab except the current tab, the result is an Empty
string.

Using Vs 2005 and Vb.NET I want to give users a message asking if they're
sure they want to close the form if they had made changes to the underlying
data. How do I detect if changes had been made by user but not yet saved?
Thanks,
Bob

I am a vb6 ADO developer looking at vb.net 2005 and ADO2.net.
I used the vb.net 2005 data wizard to bind some controls to a database. Now
I want to run a select query and have the bound controls reflect the change
from the query. How would I do that?
The wizard created a TableAdapter, BindingSource, and DataSet. Somehow I
need to run feed them a select query to update the data.

I have a data entry screen using controls bound through a bindingSource,
TableAdaptor and a BindingNavigator to move through the records.
When I have an data entry error (such as Null for a value) I get the
following error raised all the way to the App.Run command.
This is not a dataGridView, so I can not use that DataError event to catch it.
I have tried the BindingSource_DataError event, but that does not seem to
get fired.
There is...

Hi,
I have a un-typed table and 5 combo box on the form. All these combo box
have this table as the data source. Now I want to be able to select
different values using the 5 combo box. But when I change the value in
one combo box, it changes the value in all other combo box.
How can I make all the 5 combo box retain their individual (different
values)?
Thanks & Regards,

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:
