We have a VB6 COM component that I don't have control over. All of the
values are returned from method calls using byref parameters. They
frequently break binary compatibility, in fact, there are three different
versions of the component, one for dev, one for test, and one for
production, all of which are broken with each re-compile, which means I
can't use early binding and COM interop. Ugh.
Using InvokeMember, how do I get values...

I have currently an issue with the following piece of code. The assembly is
to run under com+ (as Library) and the class derives from ServicedComponent.
Code: C# - .NET framework V1.1.4322

I can't use Type.InvokeMember(...) on a remote object.
But when I use Type.InvokeMember(...) on a non-remote object in the
exact same way, I don't have a problem.
Does someone know what I'm doing wrong? Or if using InvokeMember on a
remote object is just a bad idea?
The reason I wish to use InvokeMember rather than to call the method
directly is because I don't want to install the assembly describing

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 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:...

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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. The idea...
