I get an out of memory exception when attempting to excecute the
following code:
original = System.Drawing.Image.FromFile(file.FileName,true);
I ONLY get this exception when the file is in the "My Documents"
folder or subfolders. If the file lives anywhere else on the hard
drive, I have no problems.
What could be going on here?

I have a windows application written using VB .NET that encompasses a
countdown timer modal dialog. The timer is a System.Timers.Timer with
an interval of 1 second. AutoReset is not set so accepts the default of
True. The Elapsed event handler updates the dialog box with how long
before it will close, acting as a timer itself. The dialog has a time
to close property which is checked every time the Elapsed event fires.

Hi,
I am wondering why the .NET Framework is quite different from Win32 API when
it comes to displaying system modal message boxes.
Consider the four following types of system modal message boxes (please see
associated source code below):
1) Win32 API with context ("btnWin32WithContext_Click")
2) .NET Framework with context ("btnFrameworkWithContext_Click")
3) Win32 API withOUT context ("btnWin32WithOUTContext_Click")

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:

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,...
