this is a repost with more concise code (well, for me) and better questions
(I hope....) .
given the following two classes, my intent is to use either
Activator.CreateInstance or InvokeMember pass a token into the instantiated
class DBPassword and return a string;

Hi,
On Google, one can find a lot of statements that Invoke and
InvokeMemeber work alike. However, my own experience contradicts this
statement.
1. Surprisingly, Invoke and InvokeMember methods work differently!
I'm working with some legacy COM. The COM object (CMyCOM) implements
an interface that is not dual. The interface has a method, let say,
HRESULT Foo();
The corresponded coclass defines an interface

I have a problem using InvokeMember. I have a client application that
loads a set of assemblies runtime. It creates instances of them and
calls a method which I specify in a XML file.
What I'm calling:
t.InvokeMember(widget.InitMethod, BindingFlags.DeclaredOnly
|BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance |
BindingFlags.InvokeMethod, null, newWidget, widget.Parameters);

I continue to investigate issues with making explicit InvokeMember calls
(necessary when dynamically loading classes). My quest lets me use a simple
class to invoke another class's member method by normal means and by using
the InvokeMember. By examining the underlying il code with ildasm, when
attempting to pass by reference, the il code generates a box command so that
a pointer to the actual data is passed. This is clearly seen with...

I am dynamically loading a class. One of the methods of the class takes
a short * (by reference) argument. However, the InvokeMember call used
to invoke the method of the class passings arguments in and object .
Since this is a pointer reference being passed it must be invoked in a
unsafe {} even thought the dynamically loaded class is a .Net entity.
The following is the test code that I am using to try and load a short *
into an object:...

I am writing a small program that reads a text file filled with a large

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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
