Yes, it is made by Lenovo. I don't want to remove it because I want to add to its functionality not rewrite it entirely.

I have a ThinkPad laptop with a three button mouse. I couldn't find a way to detect the center button. When I press it, ButtonFlags, ButtonData, and every thing else shows 0. Any ideas how to detect that button?

Thanks,

Your issue sounds very familiar to this user's. Check my response here, which I've recopied here:

Quote:
This issue isn't isolated to your mouse. For example, the mouse wheel tilt isn't natively supported by XP. You need to install the IntelliMouse program in order to use it. Regardless (with or without IntelliMouse), AHKHID cannot differentiate the tilts, and only reports empty messages, exactly like in your case. Simply put, if AHKHID sends back empty messages, then it means that the button isn't natively supported by the raw input device interface.

Although using AHKHID is out of the window, you may be able to use the buttons by installing the proper software. For example, in the case of the mouse wheel tilt, installing IntelliMouse in XP/2000 allows programs to receive a WM_MOUSEHWHEEL message, which you can capture by using an OnMessage function in your script. Hope this helps!

TheGood,

I have the drivers installed. But I don't know what they cause the button press to send. It's not a standard thing like WM_MOUSEWHEEL. How can I know what message is sent by this button and then capture that message with AHK?

Thanks,

MK

See this for how to trace messages.

Note Winspector Spy is no longer available at that address, see the link at the bottom of SKANs post here.

Michael,

Thanks for the links.

I used Winspector to monitor windows while I use the mystery button on them but simply pressing the mystery button doesn't send any messages to those windows.

The (mystery) center button is used for scrolling. It allows users to scroll by moving the pointing stick while it's pressed.

So, when I simply press the button, no messages are sent, but when I move the pointing stick while the button is pressed, WM_MOUSEWHEEL and sometimes WM_VSCROLL are sent. I'm not interested in those.

I think the driver listens for the button press, but I don't know what it's listening for. In Winspector, I opened a lot of the seemingly relevant processes and windows to see what messages are sent to them when the button is pressed, but I couldn't see anything...

Any more ideas? Sad

Run AHKHID's example1.ahk, select "other", scroll to right, take note of Usage Page + Usage numbers. Run example2.ahk, input Usage Page and usage, press add and call, then press the mystery button. If you see nothing, repeat with next Usage Page and Usage.

There isn't anything in the "Other" tab. The laptop comes with two navigation devices. The TrackPoint, which is what I'm interested in, and a touchpad. Both devices show in the "Mice" tab. See screenshot:



I tried to use Example 2 script with 1 and 2 values for Usage Page and Usage. But like I said, everything shows 0.

EDIT: actually, I'm not sure the two records shown in the screenshot above represent the TrackPoint and the touchpad. Because one of them shows 5 buttons, which is the total number of buttons in both, the TrackPoint and the touchpad...

Whatever that button does is simply not supported by AHKHID. The driver you have installed is able to receive input from it at a lower level than AHKHID can, and translates that input into the proper scroll wheel event, like you mentioned. So those WM_MOUSEWHEEL and WM_VSCROLL messages are probably the only visible things that occur.

The best thing you can do in cases like these is to go in the driver's options and see if you can attach a hotkey combination/program launch/anything useable by AHK.

Assigning different functionality to the mystery button through the drivers options would disable the ability to use the scrolling functionality of it. That's not what I want.

The makers of this mouse, Synaptics, provide API to their drivers! Unfortunately, I don't know how to use this API with AHK or natively.

I hope some day before I die I'll finally get my head around Win API. Meanwhile, I posted a request/job on RentACoder.com.

A while ago a was saying there could be a problem with the way AHK handles Windows 7, something about AHKHID not working or something alike...


Well, found out something:

Code:

01 01 00 00 00 32 84 0F 80 20 00 00 00                                          Visualization for XP
IR code Goes from 00 to 12 byte length (13 bytes)
01 01 00 00 00 00 00 00 00 32 84 0F 80 00 00 00 00 20 00 00 00 80 FA FF FF      Visualization for Windows 7
IR code Goes from 00 to 24 byte length (25 bytes)


Already tried switching 6th byte for 9th for the remote code, and 7th byte for the 10th byte to check the verifier byte (if is HP Remote), wont work...

Code:

        If (NumGet(uData, 10, "UChar") = 132) or (NumGet(uData, 10, "UChar") = 4)
        {   ;IT'S THE REMOTE
            If (iKey <> -1)
            {
                ;Get keycode (located at the 6th byte)
                iKey := NumGet(uData, 9, "UChar")
               
               
                ;Set prefix
                sDevicePrefix := "HPRem"
               
                ;We're gonna have to call
                bCallEvent := True
               
            }
        }


What could still be wrong???
Anything else AHK works OK in 7, only Remote script is left.

Any help will be appreciated


.::Edit::.

Something changed... updated to latest version of everything (COM, AHKHID), no more 24 bytes, just 14.


Code:
01 01 00 00 00 00 00 00 00 1A 04 0F 80 00 00



Already updated script to reflect the functions names and I'm putting just the relevant part of the script

Code:

; 0  1  2  3  4  5  6  7  8  9 10 11 12 13 14 15 12 17 18 19 20 21 22 23 24

Hey bidomo,

I'm glad to see you're making progress!

I just want to make sure I understand your situation.

IR code Goes from 00 to 24 byte length (25 bytes)

That's the output from Example 2 when you press the Visualize button, I suppose?

From your edit, you say that you're now receiving 14 bytes instead of the original 25? I find it strange that you can receive different numbers of bytes by just updating AHKHID.

Anyway, I suspect that there's an error occuring somewhere, and that's why it seems like nothing happens. Try this script, while monitoring OutputDebug with something like DebugView and see if any errors pop up. It's a simplified script (no labels to call) but with error "handling" (more like error reporting). If you successfully make it to the "Data received = " part, then it's just a matter of correctly extracting the byte from uData. Post your log here.

Code:
/*
 0  1  2  3  4  5  6  7  8  9 10 11 12 13 14 15 12 17 18 19 20 21 22 23 24

Hi,

First of all thanks for very helpful information. I am able to capture all the keys from my RF MCE Remote and able to take action.

I have a problem disabling default actions though: For example the "Windows Logo Button" sends a code that I am able to get. However, it also brings the media center program in focus.

Is there a way to disable this default functionality ?

Thanks.

Hi TheGood.

I have already tried the Step 5. I have an RF remote so that doesn't apply to me Sad

Any pointers to where I can look to disable the RF Remote default actions?

Thanks.
