multiple keydown captures

[jOch]

Hi, I am hoping to get some ideas on how to achieve the following..

I am trying to capture multiple keydowns in order to execute certain event..

I'm using WPF and C#... I've tried the following to test... it doesn't work, so I am hoping to get some ideas...



private void test(object sender, System.Windows.Input.KeyEventArgs e)
{
if (e.Key == System.Windows.Input.Key.H && e.Key == System.Windows.Input.Key.LeftCtrl
&& e.Key == System.Windows.Input.Key.System)
{
MessageBox.Show("Key pressed is: " + e.Key);
}
}



I am basically trying to capture Ctrl+Alt+h..

i havent c#, but i think you could use the "get asynckeystate"

The reason that your code is not working is that e.Key only references the most recently pressed key, so it can't be equal to 3 different keys at once.

If nothing else, couldn't you maintain a list/array of the currently pressed keys? You could update the list with handlers for KeyUps and KeyDowns and figure out whether a certain combination of keys was pressed by iterating through the array. I'm not sure if there is built-in functionality to do this, but it would be easy enough to implement.
