How to process USB events (arrival/removal) in a DLL (without using a panel handle)?

[AlePinto]

Good afternoon,

I was able to process USB Events DBT_DEVICEARRIVAL and DBT_DEVICEREMOVECOMPLETE from an application using InstallWinMsgCallback and RegisterDeviceNotification but in that case i was running an application which has its .uir file and i get the panel handle with GetPanelAttribute (..ATTR_SYSTEM_WINDOW_HANDLE..).

Now, i need to process that events from inside a DLL (which doesn`t have a .uir file and therefore i can't get a panel handle to pass to InstallWinMsgCallback) but i do not know how to imlpement it.

Thanks ind advance
