I want to be able to remove an event handler from a component. I tried a couple of things includeing the code below but can't get it to work.
Or maybe it is working but my checking is faulty.

Thanks, I needed that to be sure of myself.
There is the word Static in BindingFlags.Static which I assume does what BindingFlags.Shared would be expected do if that existed
Imports System.Reflection

Before I posted I saw much code on the internet to do what you did . They all used ClickEvent or EventClick or somethig like that and when I ran the code the GetField always returned Nothing.
I wish I knew how you found s_clickEvent. Suppose I'm interested in a SelectionChange event. Is it...
To use with a ToolstripMenuItem I had to change GetType(Control) to declaringType where Dim declaringType As Type = eventInfo.DeclaringType

I have much code. Some very old. When I found the code for controls I found it does not work.
I had also tried this which does not work:

'Might also use...
I can't get it to work. For example I tried the following but eventField is always nothing.
Even if I change the parameter type to Control and pass a Button.

I'm probably not using the correct terminology. I thought a Control had an Events property that it got from Component.
It would take me a little while to find the code but I'm quite sure some time ago I got the event handlers from a Control and then tried using the code on a ToolStripMenuItem...
The Component class has a property called Events that returns an EventHandlerList which provides the list of event handlers which can be used to get the event handlers for a control.
However, the ToolStripMenuItem does not inherit Component Control so I can't use that.

I searchedfor information on Source Control in VS2022 and it looks like I've got a some reading to do. Looks like a good thing to know about.
I would appreciate one bit of info from you now:

I have an .editorconfig as a solution items level file, which seems to do all I need.

I knew that. I was hoping someone found a way around it.
I thought maybe, if no one had already found a way, I'd try usung reflection to get the event handler from the menuitem and pass that up to the form to be added to a form's menuitem.
I shortened the names for this post.

If I use Declare Auto and the OS is UNICODE and the DLL is ANSI the runtime will not convert the UNICODE to ANSI.
Is that correct?
If so, why the word AUTO?
If I must tell the runtime what conversion to use what is the easiest way to determine the string type of the DLL?
