Detect keys down on application startup?
Hi,
I have written in C#. I would like the application to start in a "support mode" if the user is holding down Ctrl+Shift+S when the application starts.
As I need to detect the "support mode" keys before the application starts (i.e. the main form loads), I can't do it on the keydown event of the main form. This is because some of the things on the main form get initialised differently in support mode.
I can't find a way of getting the current keys pressed without responding to events.
How can I do this?

In there, you could set up a singleton GlobalConfig class that contains members that you want to init.
Your main form can then also reference the singleton, e.g. GlobalConfig.GetSingleton.

I perhaps should have said, I'm using .Net Framework 3.5.
It appears that the Keyboard class is .Net 4?... http://msdn.microsoft.com/
That's the kind of thing I'm looking for, but for .Net 3.5.

Please see the above link.
The class is created in the link, for pre .Net 4.

...Also, I can't use Control.ModifierKeys because I don't have a handle on a control yet, as it is needed before the main form is created.
Control is a static reference to the Control class, not an instance of a control.

Ah, I see. I did try code completion on "Control." to see what came up, and it only came up with a few things, none of which were "ModifierKeys". I've tried it in another class now, and I see "ModifierKeys" :)
...but how do I get the state of Keys.S without the Keyboard class? Is there something similar in Control?
