I always dispose any object with the following:
If not (obj1 is nothing) then obj1.dispose
Now I wonder if that is the correct way of disposing an object? Should I use
obj1 = Nothing after the dispose? Pls advice. Thanks.

Hi all,
Ok - I've used the word gramatically - which I'm sure is incorect, however I
mean when VS2005 lists "warnings" like this one:
Warning 1 Variable 'Command' is used before it has been assigned a value. A
null reference exception could result at runtime.
Warning 2 Variable 'Connection' is used before it has been assigned a value.

Warning 3 Variable 'Command' is used before it...

I am getting the wrong Count(*) on vb.net using the ExecuteScalar . It
returns all the rows. It doesn't seem to look at the WHERE clause. At
the same time, I am getting the correct count on "SQL Enterprise
Manager" or "SQL Query Analyser" using the same SQL statement.
Thanks in advance.
Julio.
Here is the SQL statement plus the source to the GetNumOfRow sub.

regarding the answers I got from the thread
"Does each "New" needs a corresponding "Dispose" "
(http://www.developersdex.com/vb/message.asp?p=&r=3582570&page=2)
I have some questions:
Till now, when I used dynamicCreatedControls with 'AddHandler',
I wrote the 'RemoveHandler' code in my function that was called
from the automaticGenerated Dispose function.
(I have added example at the end of this message. )

I am just wondering if I did this the best way possible. I needed to
add a double boarder around a label box. So I made a pen in the class,
and do the drawing of the rectangles in the onpaint method. Did I do
the disposal right? Is there a better way to do this? Thanks

I have my own "way" I guess of coding, like we all do, whilst I try to
maintain consistency throughout my own applications I often wonder whether
there are better ways of doing things...since I started using Visual Studio

mistakes, and its underlining of unused variables and so on...
One thing that, not so much puzzles me, but makes me think over and...

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:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
