The ExitWindows() function (API) logs the current user out of their interactive session. LogonUser() (API) can get you the access token of the user you specify, and the LsaLogonUser() (API) looks like the heavy-duty version that can actually create a new interactive logon session. I've never used any of these Lsa functions before, so I can't be of more help in that area.

I really worry about some of the things you ask here... are you trying to write programs or viruses?

It's either that or he is trying to write a custom GINA.
Not sure if you can do that with a .NET DLL really.
Why not? Maybe you can....

Hadn't thought of that. Fair point.

Might be asking a bit too much of C# but MC++ should be capable. That said, if you can do windows hooking then like you say, why not?
I dunno. I've never written a GINA; I know a bit about it from one of the products we resell (and thus I write an installer for) but beyond that I'm out of my depth.

There's a really interesting article in the latest issue of MSDN Magazine about Windows Hooking in C#. It was written by Dino Esposito, another of the C# gurus.

I'm loading an assembly and then invoking it, which I have no problem doing. However I would like to put some security into it. I use the .NET Permissions but however the assembly can assert those restrictions.
How do I invoke an assembly that I don't trust with it destroying my machine?

I've got an application to which I'm looking to add some new functionality to.
I'd LOVE to be able to offer these new functional components as "add-in" modules (similar to the add-ins in VisualStudio).
Does anyone have any advice or a suggested place to start looking for some resources on how to tackle this sort of "modular @ runtime" type of thing.
I've got NO idea on where to begin, and any poke in the right direction would be fantastic.
TIA.

How tightly coupled do you want the add-ins? Photoshop, I believe, uses a type of plug-in where, if a function (filter, in this case) in the right folder on startup, it is made available to the app. But I don't know what kind of internal interface it uses.

Good question.
What I was "visualizing" was this:
Our application has an MSOutlook-style bar, with an icon for each of the current (4) modules that are included in the application.
Ultimate Goal:
Upon deployment of an additional "module" (which will preferably be just copying some new dll's into the bin dir) and some potential "configuration" settings updates, the icons representing the new "modules" will appear in the OUtlook toolbar, and call functionality contained within the new dlls that were deployed.
Clear as mud right?

No in fact. That's quite clear. You are going to want to look into the System.Reflection namespace. That's where you can load an assembly into memory dynamically. As long as all your "modules" implement a common public interface, then you can just iterate through all the files in the bin directory and then load them using reflection.
I hope that helps. Inside C# has a really good chapter on reflection and is my all around reference manual for C#. I would highly recommend getting that and working through the examples.

A simple .config file would probably do as great. I would keep Reflection for features really requiring compiling while running, which is way beyond the static plugins you pictured.
sometimes it helps to look at the IL generated code

Interesting idea.
Do you have a suggestion on how to handle separate GUI components for each of the plugins?

HI MStanbrook
Have a look at my IRC client I wrote a while back. http://myrc.sourceforge.net[^]. It has complete support for plugins, UI the lot. My help you what Eric meant in the port below. Just Remeber the interface is the most important part. I had made several interfaces , so some plugins can have a GUI and/or Menus or nothing at all.
I must admit that was my 1st biggish C# project so some of the coding is shocking, but for you to see how I have done , it will suffice.
Hope it helps
Give them a chance! Do it for the kittens, dear God, the kittens!

How difficult this is depends upon what your requirements are.
If you want to just load add-ins at runtime, it's quite simple.
1) Define the interface you want an add-in to implement, and compile it to a .dll
2) Create a directory for add-ins off of the directory where the .exe lives
3) In the main exe, use Assembly.Load() to load in the assembly4)
4) Use reflection to find the types in it that implement your assembly
5) Use activator.CreateInstance() to create the instance
6) Cast it to your interface, and then go to town.
If you want to be able to update them on the fly, that gets more complicated. Look at:

Great article. It's a bit out of my realm for now, but looks like some interesting ideas to keep in mind while getting me feet wet!
Thanks.

I need two slightly different actions if I'm in design mode or if I'm running the actual program.
Is there a function to determine that?
|
|
|
|
|
if (this.DesignMode)?
Paul

hahaha... I tried IsDesignMode, GetDesignMode... I got to start thinking like .NET more.
Thanks bro!
