Hello. I am using Visual Studio .NET (Academic Edition) to write a VB
program. My computer is running Win XP Pro.
I am writing a calculator and requires users to enter two numbers. After
entering the numbers, they should click a button called 'Display Results'.
How can I display a dialog box prompting the users to check their entry if
they left any of the boxes empty? I have tried the .IsNaN function but in
vein.
Thanks.

I am using vb.net 2005 and SQL server 2000. In my table I have a date field
of type "smalldatetime". In my vb application, the user may or may not enter
a date value into the appropriate text box. I then want to pass the value of
this text box as a datetime variable to my stored procedure which inserts or
updates the row.
As I mentioned above, the textbox may be left blank - hence I would want to
pass a null to the stored proc. How do I...

I let the use modify the text of a combobox and then I replace the selected
item with the new text (in Keyup event).
But if he sets the Text property to an empty string ("") that sets the
SelectedIndex to -1.
Do you have any suggestion for getting around this problem?

I have found articles on line about using word interop for spell checking
with visual studio applications.
Most of the articles are several years old, though - VS2003, maybe 2005. I
couldn't find anything for VS2008.
Are there any new improvements in spell checking with VS2008?
Thanks
Bill

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...

Overview:
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,...
