How to catch keypresses (1 Viewer)

Hi

I would like to try and develop a plugin, mostly for fun. How can I detect which button a user presses on the keyboard?

Regards, Mikkel

In your plugin, override OnAction. Check for (action.wID==Action.ActionType.ACTION_KEY_PRESSED). Then you can cast the keystroke to a char with (char)action.m_key.KeyChar.

Thank you, I think I'm getting wiser

But when I try to move on in my code, I keep getting this error:

The type or namespace name 'GUIDialogOK' could not be found (are you missing a using directive or an assembly reference?)

In the top of my script I have this:

using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;
using System.Web;
using MediaPortal.Configuration;
using MediaPortal.Util;
using MediaPortal.GUI.Library;

(The above is stolen from another plugin)

I have added references to Core.dll, Utils.dll and RemotePlugins.dll (I think I'll need that one).

The code that triggers the error in the debugger is this:

        public override void OnAction(MediaPortal.GUI.Library.Action action)
        {
            char mumbojumbo = (char)action.m_key.KeyChar;
            OnButtonOne(mumbojumbo);

        }

        private void OnButtonOne(char whatever)
        {
            GUIDialogOK standbyMessage = (GUIDialogOK)GUIWindowManager.GetWindow((int)GUIWindow.Window.WINDOW_DIALOG_OK);
            standbyMessage.Reset();
            standbyMessage.SetHeading("Testing popup");
            standbyMessage.SetLine(1, "whatever...");

            standbyMessage.DoModal(MediaPortal.GUI.Library.GUIWindowManager.ActiveWindow);


        }

Could you perhaps lead me on the way again? I'm quite new to this and have only done a little Visual Basic many years ago, but believe I know my way around PHP and also ASP...so should be able to learn on the way!

Thank you.

Add a reference to Dialogs.dll. It's in plugins\windows\.

Thanks. I'm getting good progress with my plugin and got the "catch keypresses" working and about 60% of the functionality. Now, this will work fine for my own purposes, since I use a remote that emulates keypresses via an external process.

However, I would like to be able to support users with a remote that sends commands directly to MediaPortal, like thoses that uses the ever popular MCE remote. What should I look for in that case?

I use this to catch keypresses at the moment:

if (action.m_key != null && action.wID == MediaPortal.GUI.Library.Action.ActionType.ACTION_KEY_PRESSED)
{
//Do some routines with Shift and Ctrl keys and the like...
}

How would a snippet like this look like, if I want to catch a press on the "Play" button on a MCE remote?
