CreateInstanceF romAndUnwrap not working when called from Excel

Hi,I'm getting a "assembly or one of its dependancies could not be found"
error when running the code below.The code works fine when called by a .NET
program, but fails when called by an assembly instantiated in Excel 2000.
The CreateInstanceF romAndUnwrap looks for the assembly in Excel's "Default
file location" setting, even though the correct path is set by
setup.Applicati onBase.

What am I doing wrong?

Thanks.Francis Gingras

// Get reflection permission
ReflectionPermi ssion reflectionPerm = new
ReflectionPermi ssion(Permissio nState.None);
reflectionPerm. Flags = ReflectionPermi ssionFlag.Membe rAccess;

// Get file permissions
FileIOPermissio n fileperm = new FileIOPermissio n(FileIOPermiss ionAccess.Read
| FileIOPermissio nAccess.PathDis covery,
Path.GetDirecto ryName(Assembly .GetExecutingAs sembly().Locati on));
fileperm.Assert ();

AppDomainSetup setup = new AppDomainSetup( );
setup.Applicati onBase =
Path.GetDirecto ryName(Assembly .GetExecutingAs sembly().Locati on);

adapterDomain = AppDomain.Creat eDomain("MyApp. Adapter", evidence, setup);

"MyApp.Loader") ;

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.

For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. 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.
