Hi,


I have a new notebook (dell XPS M1710) and it has some led's on the side, front and back of the casing. I got the 'crazy' ID to let these lights notify me when someone sends me a message and the window is minimised (or at least 'not focused'). This could be really useful when playing games or when I'm not at my notebook for the moment.

To do this, I would need two things:
- To know if the window has focus or not when OnEvent_ChatWndReceiveMessage is triggered
- To know how to execute a batch file that will trigger the appropriate lights.

Can anyone give me some tips as to how this can be done? I'm not asking for any complete scripts, just for some commands that I can use to build my own script . All help is welcome!

Greets,
Dauntless

I think this should work, haven't tested it though:

code:

---

function OnEvent_ChatWndReceiveMessage(ChatWnd, Origin, Message, MessageKind) {
    if(ChatWnd.Handle !== Interop.Call('user32.dll', 'GetActiveWindow')) {
        var objShell = new ActiveXObject("Shell.Application");
        objShell.ShellExecute("C:\\PATH\\TO\\THE\\BAT\\FILE\\ledflash.bat", "", "", "open", 0);
    }
}

---

Thank you for your little script! I'll look into the commands you have used and I'll try to figure out how it works exactly (although it looks quite self-explanatory).

Where can I find the documentation for user32.dll ? (I google'd, but it gave to many different results...)

//EDIT
It doesn't appear to be working, but at least I can try for myself a little while .

I now have this, and it's working:

code:

---

function OnEvent_ChatWndReceiveMessage(ChatWnd, Origin, Message, MessageKind) {
    if(ChatWnd.Handle != Interop.Call('user32.dll', 'GetActiveWindow')) {
        var objShell = new ActiveXObject("Shell.Application");
        objShell.ShellExecute("C:\\Documents and Settings\\Dauntless\\My Documents\\My Downloads\\xps-led-control-exe\\police.bat", "", "C:\\Documents and Settings\\Dauntless\\My Documents\\My Downloads\\xps-led-control-exe", "open", 1);
    }
}

User32.dll is part of Windows.

The documentation is stored in the MSDN library.

GetActiveWindow()'s documentation is here:
http://msdn2.microsoft.com/en-us/library/ms646292.aspx

Thank you .

How can I know which functions I can use and which functions I can't use?

I tried this:

code:

---

Interop.Call("User32.dll", "ChooseColor");

---

quote:

---

Interop.Call failed to locate function "ChooseColor"
Error: unknown (code: -2147467259)
       File: Testje.js. Line: 4.
Function OnEvent_Initialize returned an error. Code: -2147352567

ChooseColor isn't a function, it doesn't exist. If you go to the link TheSteve has posted you see a list of functions, which are called Windows API functions (for user32.dll).

PS, for running a file (no matter what kind), you can also use:

code:

---

new ActiveXObject("WScript.Shell").Run("\"C:\\path to file\\file.bat\"");

---

Ow, sorry, ChooseColor isn't declared in user32.dll . But 'CreateDialog' IS, (http://msdn2.microsoft.com/en-us/library/ms645434.aspx) and I still get the 'failed to locate function' errror.

code:

---

Interop.Call("user32.dll", "FunctionName", "Parameter1", "Parameter2", etc);

It was just a little test .

I didn't knew they were required because it didn't say 'required' (I thought it did with other functions...)

But now I know that it is possible, so I'll go look into those functions and play around some more .

Thank you for your help!

Optional parameters usually say "Optional" somewhere (I believe they also have their parameters in square brackets: [Param1])
