wmi-query

I'm using WMI (Win32_NetworkAdapter) and trying to get the details of attached physical network adapters either wired or wireless and avoid virtual adapters, etc. Reading this article it explains that you have to do some clever querying on WMI to eliminate virtual adapters and attempt to only return real physical adapters. Reading this post it explains that you can compare the text in the "Description" of the network adapter to see if it includes "Wireless", "802.11", or "WLAN", if it does, then most likely the adapter is a wireless adapter. With today's .Net versions and other advancements,

I am using inno setup to make an installation file. It required to pull local ip address (which I able to do by querying Win32_NetworkAdapterConfiguration) and check if a specific port is open for the software to run on (which I am currently looking for an answer). I realize that WMI Win32 classes contain so many useful information. So I wonder which Win32 class should I use to check on this port given that if it is possible to do that? Thank you, RRUZ AFAIK the only WMI class to check if a given port is open is the NetDiagnostics WMI class and the ConnectToPort method, but this class only is

WQL (basically SQL for WMI) does not support a TOP or LIMIT keyword. Sql Server used TOP and many other RDBMSs supprt LIMIT etc. Is there a workaround to emulating a SELECT query to behave as though it had a TOP/LIMIT clause that limits the result set to some arbitrary number? Or is there some other WQL-specific keyword that works like TOP or LIMIT? Justin Grant Nope, there's no way to simulate TOP using WQL alone. Exception: if you're lucky enough to be querying a WMI class which has ungapped, ascending numeric instance numbers used as keys, then you can use greater-than and less-then

I found Determining the network connection link speed and now I am trying to correlate the data from Win32_PerfRawData_Tcpip_NetworkInterface with Win32_NetworkAdapter (or Win32_NetworkAdapterConfiguration ). On the class Win32_PerfRawData_Tcpip_NetworkInterface I don't see any index or unique key that I can use to reference Win32_NetworkAdapterConfiguration or Win32_NetworkAdapter. I tried to use the Name in Win32_PerfRawData_Tcpip_NetworkInterface and Win32_NetworkAdapter`, but still they look different. e.g. Name: Intel(R) PRO/1000 PL Network Connection vs Name: Intel[R] PRO_1000 PL Network

I wonder if the PNPDeviceID of an USB drive is unique (at least a charge of identic devices) and if the ID does not change. Thanks in advance. As far as I know -- No. For example, "USBSTOR\DISK&VEN_LG&PROD_USB_DRIVE&REV_1100\AA04012700014149 &0 " - is a device id of a usb stick. For all such given usb sticks device id will be the same. But Windows adds an instance id of device (" &0 "), so it can distinguish them. If you plug two same usb sticks the device id of each of them will be different, for example: USBSTOR\DISK&VEN_LG&PROD_USB_DRIVE&REV_1100\AA04012700014149 &0 USBSTOR\DISK&VEN_LG&PROD
