is there a way to determine if a form object actually exists?
if i use the following syntax:
varTextField = Request.Form("txtFormField")
then varTextField = "" which gives the same result whether the input field
"txtFormField" doesn't exist or it does exist but it was left empty
why can't i use something like?

I am writing a VB.NET application in Visual Studio 2003. I have written a
method that handles several events, such as closing a form and changing the
visible status of a form. I have some code that applies to all these
events, but I need to have specific code execute when the form closes. The
properties for this method are sender (the originator) and e (event
arguments). I know how to get typeof (sender) to determine what form or...

Hi everybody!
I wonder if this is possible?
I need to determine if a client is using "windows classic folders" or
anything else. If I instantiate a Shell ActiveX object is there a way
of obtaining this information from javascript? (I know that the user
will get prompted about allowing such an operation, but I am willing
to live with this). Because of the way one of my pages work, I need
to know this information in order to "cover up"...

I'm having problems working with a streamwriter object. After closing the
streamwriter and setting it to Nothing, I try to delete the file it was
writing to, but I always get the following error message:
"The process cannot access the file "whatever" because it is being used
by another process."
I've even tried opening another file using the same streamwriter object
before deleting the original file, but it's no use. Something keeps...

I am trying to determine if a file exists on a web site but I cannot get a
match. I have verified that the file does exists in the specified directory
(I verified the case of the file and directory name). The code (below) is

I need to determine if a file exists using code.
I tried using the system.io.file.exists function, that will appears to
locate the file if I use the complete filespec, when I move the project to
the web server, that command will not work because I can not specify the
entire path, just the path relative to the default project folder.
Example
This is the path my image property uses: "~/image/NoImageAvailable.jpg"

I searched using Google, on the web and in the newsgroups, and found nothing
on this topic. Hopefully that means I just don't understand what I'm
supposed to be doing here. :)
The problem:
I am trying to use the SaveFileDialog class to get a filename, which is
subsequently opened for writing (write access, read sharing, but using
read/write sharing doesn't make the problem go away anyway). Sometimes, on

I'm wondering if there is an easy way to programmatically determine if an
assembly is installed in the GAC.
This would be similar to our ability to easily determine if a file exists
(File.Exists(path)) - but for an assembly, of a particular version, etc in
the GAC.
I have googled this and failed to find anything useful.
Thanks

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,...
