UINT16 and UINT32 conversion

3 posts in this topic

#1 ·  Posted (edited)

Morning! I'm trying to convert a UINT16 (and possibly UINT32) into usable information, specifically for the Win32_PnPEntity class "Availability" property. I can't for the life of me figure out how to do this properly; keeps displaying 0 instead of something like 0x1. Perhaps I'm just "doing it wrong". Information regarding this WMI class is shown here http://msdn.microsoft.com/en-us/library/aa394353%28v=vs.85%29.aspx . And I was able to find a VB way of handling this http://msdn.microsoft.com/en-us/library/8444cfyw.aspx but again I'm unsure on how to relate this to AutoIT. There's also this codeguru WMI enumeration script that talks about it http://www.codeproject.com/KB/scripting/wmiadmin.aspx .

Any help would be much appreciated and you'll have my accolades :)

There is nothing special about a UINT type, it's just a number. The problem is that the Availability property doesn't return a value at all (nul string) for many devices, depending on the device firmware, driver, etc.

Global Const $wbemFlagReturnImmediately = 0x10
Global Const $wbemFlagForwardOnly = 0x20
Global $wbemFlags = $wbemFlagReturnImmediately + $wbemFlagForwardOnly
Global $objWMIService = ObjGet("winmgmts:\\" & @ComputerName & "\root\CIMV2")
Global $colItems = $objWMIService.ExecQuery("SELECT * FROM Win32_PnPEntity", "WQL", $wbemFlags)
Global $sMsg = ""
For $objItem In $colItems
    $vAvailability = $objItem.Availability
    $sMsg &= ("Availability: " & $vAvailability & "; " & VarGetType($vAvailability) & @LF)
    $sMsg &= ("ClassGuid: " & $objItem.ClassGuid & @LF)
    $sMsg &= ("CreationClassName: " & $objItem.CreationClassName & @LF)
    $sMsg &= ("Description: " & $objItem.Description & @LF)
    $sMsg &= ("DeviceID: " & $objItem.DeviceID & @LF)
    $sMsg &= ("Manufacturer: " & $objItem.Manufacturer & @LF)
    $sMsg &= ("Name: " & $objItem.Name & @LF)
    $sMsg &= ("PNPDeviceID: " & $objItem.PNPDeviceID & @LF)
    $sMsg &= ("SystemName: " & $objItem.SystemName & @LF)
    $sMsg &= ("----------------------------------------" & @LF)
Next
MsgBox(64, "Results", $sMsg)
