When writing VB or VBA code that works with databases or other external
libraries that cannot be trusted to automatically do the right thing when
references to their objects are arbitrarily released, some thought must be put
into how to make sure the objects will all be closed and released in the
correct order, even in the result of an error.
This requirement can make our code really ugly, even following the best of
commonly known best...

I am seeing a very strange problem as follows...
I have a loop where a fair amount of processing is going on and near
the top of the loop I access a class that has only static helper
functions to perform some calculations. After some number of
iterations, randomly, I'll get an uncaught NullValueException error on
one of these calls, as if the class name is being treated as an object
reference and is null. Here is some psuedo-code to...

First off, I'm sorry if this isn't the write thread to post this message but
I couldn't find one dedicated to System.Drawing.
I'm developing an intranet application in VB.NET that uses a Hosted Windows
Form (HWF) dedicated to image manipulation. This HWF is also supposed to
allow the user to print an image to their default printer. I'm using a
System.Drawing.Printing.PrintDocument object to initiate printing, and
everything works locally...

and after that much typing, I don't want to lose it)
I am considering general error handling routines and have written a sample
function to look up an ID in a table. The function returns True if it can
find the ID and create a recordset based on that ID, otherwise it returns
false.

Hello group,
I have a problem with template classes and inheritance. I've searched
on the internet to find a solution but all the examples look the same
as my code (as far as I can tell) and I can't find my mistake (maybe
there's something wrong with my eyes).

I've got an error that I simply cannot locate:
I've got a form in which I use a datareader object to read information from
a db. After the read, I close the reader and I dispose of both the reader
and the command object (but don't close the connection which is public in
the solution).
The first time i open my form from a parent form, there is no problem.
Everything works fine. I then close down my form, and I dispose of the form.

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,...

Now, this would greatly impact the work of software developers. The idea...
