I have been working for some time to 1) detect tab and shift tab
events 2) control the focus on the basis of these events. I have
found that I can do this, but continue to have nagging problems.
One of the main problems at this point lies in cancelling the event.
I have found that the TAB fires the onkeypress in NN, but not in IE.

Other than throwing an exception during the execution of an object's
constructor, is there any way to cancel creation of the object in such a
way that it leaves a reference to it null or undefined. That would enable
the simple test:
var ref = new someObject();
if( ref ) {
// Object created successfully
}

How can I cancel all running processes in my application when I click on the
Cancel button? When the Run button's clicked, it creates an instance of a
specified class and runs a method that reads each line of a file, processes
it , and writes it. With the Cancel button, I'd like to cancel this method.
Is this possible?
Thanks.

However, if they change the data in the fields and then select a new item without saving, I want to display a message box that warns that their changes will be lost, and asks them to confirm whether to continue. Sounds simple
Unfortunately, the ListView's...

I have a combobox control on the form. When the user makes a change, I want
to validate a condition before permitting the change. If the condition is
not met, I want to return the ComboBox text back to its previous value. He
is what I tried.
(1) Validating event does not work because user is not exiting the control.

Although I am aware of methods to kill an existing thread that is
explicitly created in code, I am wondering if a method exists to do so
with a pool thread that would be used when calling BeginInvoke on a
delegate? I suspect that there isn't, but have been unable to confirm
this suspicion.
Thanks.

After running a query, if the DataTable has records, I go on to process them.

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. ...
