Depends on how you look at it. You could also describes these techniques as your specific 'implementation proposal to upgrade the plugin system from modal plugins only to both modal and non-modal, which is a rather big feature... But we all agree this is important stuff, so here we go...

1. Yep, you'll get it.

2. I honestly do not know what you would need your own HModule for inside a DLL, I don't think I've seen this technique being used (but perhaps I've been using frameworks that were abstracting it away?), can you give me some technical pointers/references here? (*)

3. Yep, you'll need some way if getting this info, through callback or perhaps as an argument to PluginExecute/PluginInitialize. We'll need to fiddle around with the exact HWND value passed (DeleD, like any Delphi application, has a hidden main application window... I think that's the one we want to pass around, but we could also do the visible main window, or perhaps the owner/parent window shouuld be context-based).

4. Uhmmm... we can probably do this, but what exactly where you going to do with it? Skinning windows? If you just want your plugin to be notified of changes in the underlying data then I think that's what we would be needing to make, some form of notification system.

I am by the way a bit surprised your hacky-way-to-retrieve-the-main-window isn't robust, I've got commercial business-applications running in the wild using such methods to hook into 3rd party closed source stuff. Any things in particular that go wrong?

[edit]Ok, so curse my Delphi background, I never knew that our HInstance and HModule were one and the same thing... So I have been working inside a framework that has abstracted the retrieval of the HModule way from me (at the lowest level, it just looks up the HModule of the address of the function that gets called at initialization using a VirtualQuery). The Delphi Run Time Library is very much proven technology (i.e. it is used in every Delphi DLL around), so I see no compelling reason to do things another way. My suggestion would be we just document such a method (as a 'how to') and put it into any example code as well.[/edit]

[edit2]I've been thinking about this some more, and I am currently leaning towards an optional PluginInitialize method that gets you both the hwnd and hmodule. The fact that Jeroen and me are living inside a framework that makes retrieving the hmodule trivial doesn't justify making the life of developers in other environments harder.[/edit2].
