Hi guys,
might be a silly question, but i'm wondering whether it is even possible to
generate access violations when using C#?
I'm new at c# programming, but i have some experience with c++. Now that i'm
using c# i can't see how i should mess up memory like that without the use
of pointers or adresses.

IMO you can do that using P/Invoke and COM interop in the unproper way and
maybe if you mess up something in the unsafe block...

Hi,
It's much more difficult, but possible if using P/invoke.
The more common problem (not sure if quilify as access violations) is when
you try to invoke a member of an instance without being assigned first

Hello!
I am writing VBA code in Access 97 to import an Excel 2000
Spreadsheet. I had hoped to do this using ODBC, but that was not to
be, for who knows what reason.
The problem is that I import the excel file into a table in Access
that I name X. Then I run an append query to import the data into
another table.
I get an error message that says it "can't append all the records" due

Why does xmlData.getElementById('1') return null and

The minimal code (VB.NET 2003) needed to show this problem is shown
below. All I do is loop through the records in the table and update
them without making any changes. Out of 600 records, about 40 of them
throw Concurrency violation errors in the update, and my GetAllColErrs
function provides no output. In comparing the rows that throw errors
with those that do not, I could find no pattern.
It is obviously a bogus error, as the...

My question, stated as simply as possible, is: must a constraint
violation, as defined by the standard, cause compilation to halt?
I believe that in the presence of a constraint violation, at
least one diagnostic is required, which, at the discretion of the
compiler writer, may be either an "error" or a "warning."
Generally however, an error halts compilation and a warning does
not. This would seem to imply that it is up to the compiler...

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.
