You should rewrite the data manipulation for ADO.NET instead of using
Interop. It is less buggy and will perform much better.
If you MUST stay in ADO, you will have some issues. It is better to pull the
value and then compare rather than attempt the pull and compare in the same
statement. You can then debug what is causing the error, as it will break on
one or the other.
As it stands, my guess is the recordset value is being pulled as a string
and compared against a different data type. As the code is not ADO.NET, but
it is being used in the .NET world, I am not surprised.

Hi Gurus
In my quest in putting my first javascript together, I am now trying to
conquer something that seems trivial, but has taken me hours.
I would like to format a field in a form once the person has completed it.
The format should be "00". For example, if the person puts 1 then it should
become 01 and if the person puts 12 in the field then it should stay like
that. If the person puts 2004 then it should become 04, and if the...

Hi All,
I have a number guessing game in which users try to guess a random number.
Obviously, input is required of type int.
BUT, when a user inputs a string the program will result in an undesired
infinite loop.
Now, I know a string is not what we're after but in terms of error-handling;
How can we prevent users from entering a string?
and if we can't do that:
How can we make sure if a string is entered, it is realized and discarded.

Re: ASP.NET 2.0
I would like suggestions or code examples on how to collect a variable
length list of input data (item# & item quantity specifically).
I thought that I could accomplish this using a GridView that has ViewState
enabled, an ObjectDataSource to process the submitted list, textboxes for
getting new item data and an add button.
Does this approach sound feasible or are there better alternatives?
My problem is that I don't...

I use this function that I wrote for inputting strings. It's meant to
return a pointer to mallocated memory holding one input string, or 0 on
error. (Personally, I prefer to use 0 to NULL when returning null
pointers.) It looks pretty watertight to me, but my version of lint
complains about use of deallocated pointers, etc. Is this code
completely safe on all input, or have I missed something?

I have a fully-portable C program (or at least I think I do). It works
fine on Windows, but malfunctions on Linux. I suspect that there's
something I don't know about the standard input stream that's causing
the problem.
Here's how I wrote the program originally:

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.

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,...
