Hi
I'm writing a program that needs to read from a file. In order for the
program to be robust, it should somehow check that the file isn't corrupt,
or stuffed in any way. For example, that file may have been created but a
crash occurred at that point in time (while it was being created), damaging
the file. Now, my program which needs to read from this file, should first
check that it's in good condition, and that it hasn't been...

I'm sure this is a really dumb question, but how do you detect a variable
type in Python?
For example, I want to know if the variable "a" is a list of strings or a
single string. How do I do this?

I'm using SQL Server 2000 and on my page, I'm simply creating a

However, how can I prevent from getting errors when a field is null?
I've tried something like this (experimenting with IsDBNull):

I have a webpage that detects whether Shockwave Player is installed and
the version number. The javascript/vbscript that I use has worked fine
until the latest release of the Shockwave Player. I am still able to
detect the Shockwave Player and the version number when using
Firefox/Netscape, but not with IE. I have my own detection script that
I use, but I've also used the detection scripts supplied from
Macromedia, but it still won't...

I wandering about the common proctice of some UA's producers to spoof
the UA string to pretend to be another browser (most often IE).
Shouldn't it be considered as a trademark violation of the relevant
name owner? If I make a whisky and call it "Jack Daniels", I most
probably will have some serious legal problems. "Mozilla" partially
appeared because NCSA stopped them from using "Mosaic" in the UA
string.
Is it some different...

In C#, using the StreamReader, how do I detect when you get to the end
of line. I am reading a text file using the Read() function and I need
to detect the \n\r, but everything I try does not work. I am sure that
this probably fairly simple, but I have not been able to figure it out.

Is there a general method for detecting that a user has changed the
record currently visible on a form, whether this is by hitting PgUp or
PgDn or clicking on a navigation button, even if no change has been
made in any control?
I'm thinking of a situation in which a number of records have been
entered on a form and the user is cycling through them to check the
data entered. I want to be able to detect this and update certain

When using createEvent, an eventType parameter must be provided as an
argument. This can be one of those specified in DOM 2 or 3 Events, or
it might be a proprietary eventType.
My problem is testing for support of particular eventTypes - the DOM 2
Events Interface DocumentEvent says that if the eventType is not
supported, it throws a DOM exception. This makes testing rather
tough - if you try something like:

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
