It's a WMI script. I take Win32_Process as an example this time, as there was an interest in GetCommandLine recently, which can be obtained via WMI too.
| Code: | COM_Init()
;WMI_Query("\\.\root\cimv2", "Win32_Process")
WMI_Query("\\.\root\cimv2", "Win32_Process WHERE Name='svchost.exe'")
MsgBox % "<CommandLine>`n" . WMI_Query("\\.\root\cimv2", "Win32_Process WHERE Name='autohotkey.exe'", "CommandLine")
COM_Term()
Return
WMI_Query(Namespace, Class, Property = "")
{
psvc := COM_GetObject("winmgmts:{impersonationLevel=impersonate}!" . Namespace)
pset := COM_Invoke(psvc, "ExecQuery", "SELECT * FROM " . Class)
penm := COM_Invoke(pset, "_NewEnum")
Loop, % COM_Invoke(pset, "Count")
If COM_Enumerate(penm,pobj)=0
{
If Not Property
MsgBox % COM_Invoke(pobj, "GetObjectText_")
Else sResult.=COM_Invoke(pobj, Property) . "`n"
COM_Release(pobj)
}
COM_Release(penm)
COM_Release(pset)
COM_Release(psvc)
Return sResult
}

| Works for me, thanks. It fills a frequently asked field (often for hardware information requests, like HID). |

Is it Pro or Home edition?
If you're on Pro, would you try wmic.exe or wbemtest.exe? They reside under system32\wbem folder which is actually on Path. Do they work?
Or if you're on Home, you may try to see if work MS's apps like scriptomatic or wmicodecreator, both can be downloaded from MS site. |

The file is missing... I guess I deleted it. Anyway, I posted the script in top post. |

Cool! Great work!
With “Win32_USBControllerDevice” I can have a list of the installed USB devices. I have to filter out the joysticks, but how can I know, which one is connected now, and what is its OEM name? Could you direct me to some documentation or example code? |

could you post the sample code that outputs the list of usb devices?! |

I got the usb-list code from Guest++.
Stupid question: If I can get the data from the registry, why should I use the COM interface? Is it faster, more reliable, more flexible...? |

is it a joystick/joypad that is listed in the device manager as usb hid device? than you should find it in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\HID
if it is something else: what are you searching for? |

I need a list of all joystick names currently plugged in, with their number, so the user can select which one to use. I could steal the list from the control panel app Game Controllers, but it does not tell their number AHK uses (because already removed joysticks still occupy numbers). In the thread I linked above I described a solution via reading the registry and calling winmm\joyGetPos with each one, but it has some problems: winmm\joyGetPos leaks memory, the registry sometimes very slowly gets updated. I hoped for a faster and more robust solution, like reading the information joyGetPos returns, but no one seems to know how to use it (the last field of the returned struct). |
