How to check if Windows is busy by installing any driver?

问题

I write program which installs usb device driver by means of dpinst.exe. At program start I want to check if Windows is busy by searching/installing/updating some driver. (Main scenario I want to avoid is launch of dpinst.exe while Windows is searching driver for plugged device.) How can I check that?

回答1:

Solution is to use CMP_WaitNoPendingInstallEvents function. Example here.

回答2:

You can use Process to look if another instance of dpinst is already running.

Process[] processlist = Process.GetProcesses();

foreach(Process p in processlist){
    if (p.ProcessName.StartsWith("dpinst"))
      ...
}

I would bet that this is unnecessary : the scenario you are trying to avoid is already being managed by dpinst/Windows itself.
