Hi, I'm getting an exception that really has me stumped. It's sporadic
at best, it's only happened a handful of times.
This particular time it happened when the user pressed 'Alt-S' to save
the data that they were entering.
Following is all exception information.
Any thoughts much appreciated.
Cheers

now catch the ListView's scroller and start to move it downwards. you have
to hold the constant speed so that the ListView is constantly repainted.

Excetremely annoying problem, I've an application with a long startup time.
So I created another form with my logo in it to as a splash screen.
The splash screen is run from another thread and is communicated solely
through static method and Invoke()'s
However, when I close my second form, the first one (main window) is hiding
under all the windows on the desktop.
If I don't close the splash screen, then everything is fine.

I was under the impression that frames could be used in Windows forms in
earlier version of VB. However, in VB 2005 Express I don't see any such
tool/control. Is SplitContainer used for this purpose in VB 2005?
I want to create a frame in a Windows form because I'd like button clicks on
the left side of the form to change the form elements shown in the right
side of the form. Would each of the buttons on the left require a...

Hi,
I have been trying to use a .net Forms control in my webpage to open up
an application(notepad) on the client. The control works fine when
embedded in a windows form, but I keep getting a security exception
when trying to run it from my webpage on my intranet. I have tried
playing with the Code Access Security settings, but I can't get it to
work.
What do you think?
Thanks,

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,...

Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
