I like AHKHID for my remote that much, I refuse to not use it! Thanks for AHKHID.

The Play and pause buttons should be separated for MCE, allows me to remove the playback OSD (pressing play twice, and I get my Thumb workout too!!!), unless I find a nice replacement for MCE (tried a lot of them, but MCE stills ahead), and if some other Software convinces me, MCE will have to pray for his life (and bye to my badass thumb...).

I will be digging a lot more in my free time.


Forgot to say, ControlSend doesn't work with MCE, and I don't see how PostMessage can help, as I get nothing from winspector, and that's how I found that info, thanks to failure.

In another words, how do you disable the original key presses of the MCE remote such as 0-9 numbers and replace them?

Hi,
i don't know if this is the right place to ask for, but i need help.
I want to intercept the press of special keys on my Media center remote controller (as the red, green, yellow and blue keys), and use them in a autohotkey script. Is it possible? And how?

Thank you.

Bye.

Can't you use SendInput? Or is the MCE interface not always in the foreground? I don't see why ControlSend shouldn't work. Did you check with Winspector to make sure that MCE receives the keys sent by ControlSend? Try also doing (for example if you're trying to send the A key):
Code:
        Send {a Down}
        Sleep 50
        Send {a Up}

Look here. :)
And here's the relevant section:
Quote:
On the other hand, if you do end up finding an entry in the Other section of Example 1, then you can make the remote stop generating those keyboard presses by doing the following steps:
1. Go to Device Manager
2. Expand the "Keyboards" tree
3. You should find a device (ie. your remote registered as a keyboard) other than your usual keyboard there. To make sure it is indeed your remote, you can compare the name you found in Example 1 with the name you'll find when you right-click>Properties>Details on the keyboard item in Device Manager.
4. Once you found the keyboard entry associated to your Kensington Presentation remote, right-click the item and select Uninstall

Hello MonsterMash,
Please follow the tutorial you'll find in the second post of this thread.

Hello MonsterMash,
Please follow the tutorial you'll find in the second post of this thread.


Hi, thank you! But i need much help. If i'm right, the following function is the most important:

Code:
InputMsg(wParam, lParam) {
    Local devh, iKey, sLabel
   
    Critical
   
    ;Get handle of device
    devh := HID_GetInputInfo(lParam, II_DEVHANDLE)
   
    ;Check for error
    If (devh <> -1) ;Check that it is my HP remote
        And (HID_GetDevInfo(devh, DI_DEVTYPE, True) = RIM_TYPEHID)
        And (HID_GetDevInfo(devh, DI_HID_VENDORID, True) = 1118)
        And (HID_GetDevInfo(devh, DI_HID_PRODUCTID, True) = 109)
        And (HID_GetDevInfo(devh, DI_HID_VERSIONNUMBER, True) = 272) {
       
        ;Get data
        iKey := HID_GetInputData(lParam, uData)
       
        ;Check for error
        If (iKey <> -1) {
           
            ;Get keycode (located at the 6th byte)
            iKey := NumGet(uData, 5, "UChar")
           
            ;Call the appropriate sub if it exists
            sLabel := sPrefix "_" iKey
            If IsLabel(sLabel)
                Gosub, %sLabel%
        }
    }
}


First of all, i don't understand what are wParam and lParam passed to this function. Can you light me?

Example 2 contains OnMessage(0x00FF, "InputMsg"); this causes InputMsg() to be called whenever the script receives a WM_INPUT message. 0x00FF is the numerical value of WM_INPUT as defined in the Windows SDK. The script must register for Raw Input before it will receive WM_INPUT messages; Example 2 demonstrates how. You should not be calling InputMsg() directly. WM_INPUT Notification at MSDN describes how lParam and wParam may be interpreted and Raw Input contains an overview of the Raw Input/HID API. You probably don't need that much detail if you're using TheGood's script, though.

Thank you! Finally i began to understand something :D.

I made some experiment, and wrote this code:

Code:
#Include %A_ScriptDir%\AHKHID.ahk


hGui := WinExist()

;Intercept WM_INPUT messages
WM_INPUT := 0xFF
OnMessage(WM_INPUT, "InputMsg")

;Register Remote Control with RIDEV_INPUTSINK (so that data is received even in the background)
r := HID_Register(65468, 137, hGui, RIDEV_INPUTSINK)


InputMsg(wParam, lParam) {
    Local devh, iKey, sLabel
   
    Critical
   
    ;Get handle of device
    devh := HID_GetInputInfo(lParam, II_DEVHANDLE)
   
    ;Check for error
    If (devh <> -1) ;Check that it is my HP remote
        And (HID_GetDevInfo(devh, DI_DEVTYPE, True) = RIM_TYPEHID)
        And (HID_GetDevInfo(devh, DI_HID_VENDORID, True) = 1118)
        And (HID_GetDevInfo(devh, DI_HID_PRODUCTID, True) = 109)
        And (HID_GetDevInfo(devh, DI_HID_VERSIONNUMBER, True) = 272) {
       
        ;Get data
        iKey := HID_GetInputData(lParam, uData)
       
        ;Check for error
        If (iKey <> -1) {
           
            ;Get keycode (located at the 6th byte)
            iKey := NumGet(uData, 5, "UChar")
       inputChecker(iKey)
        }
    }
}

print(iKey, iDescription)
{
IfWinExist Magnifier
WinClose ; close magnifier if it's open
Progress, B2 fs24 zh0 WS700 CW0E4D9A CTFFFFFF, Key Code: %iKey% - Key Name: %iDescription%, , , Courier New ; show last keypress onscreen

}

inputChecker(iKey)

else if iKey = 11
iDescription := Enter
print(iKey, iDescription)
Return
}

RemoveNotice:
SetTimer, RemoveNotice, Off
Progress, Off
return


In my mind this must notify on screen every time i press a key on my remote controller, and write the key code and a key description. But it does not work.
What did i wrong?

Thank you again.
Bye.

The most obvious problem is the recurring syntax error:
Code:
iDescription := DVD Menu   ; bad
iDescription := "DVD Menu" ; good
iDescription = DVD Menu    ; good

You can find detailed info (which I'd tried to explain before in page 5) here http://mediacenterguides.com/sites/default/files/IRCodes_ReportMappingTable_InputINF.pdf (the pdf is not mine)

this reg file will disable 0-9 for you...


Code:
Windows Registry Editor Version 5.00

Every send mode works while MCE is in the foreground, but ControlSend won't work in foreground neither background.

I'm gonna try again and check window spy

Thanks bidomo.
I haven't looked at the PDF file in-depth yet, but when I do, I will modify the first post to show how to use this method to disable keypresses.

Thank you, i'm not so expert in this language.

But also with these modifications the script does not work. There must be something else...

Thank you.

MonsterMash,
Do you have exactly the same remote as me? (I see you're using the same ProductID, VendorID, etc... as me).
Also, you should debug it, using MsgBoxes or OutputDebug (more recommended), to see where exactly you lose contact.

My remote isn't the same of the your, but using your example2 i saw that all parameters are the same (ProductId, VendorId, VersionNumber, Usage Page and Usage).

I don't know most of IO functions, now i will look for some documentation about MshBox and OutputDebug.

Thank you, bye.

I followed the instructions through Example 1 and got the device's

Vendor ID = 2683
Product ID = 53248
Version Number = 1
Usage Page = 1
Usage = 4

Then I input the usage page and usage value into example 2 and added then called so I could start getting the raw data and data started flooding into the listbox. It never stopped. So I'm at a loss for what to do next since its almost impossible for me to extract any data from it.

This is the HID I want to bend to my will.

Certain buttons do accept commands from autohotkey but there are other areas of the Joystick that dont like the tuner dial + toggle switches + Communication buttons

This is where I got the drivers which were made specifically for connecting the Joystick to the computer.

I used a USB adapter that allows me to plug Xbox controls to the PC for the connection.
