How to get friendly device name from DEV_BROADCAST_DEVICEINTERFACE and Device Instance ID
- by snicker
I've registered a window with RegisterDeviceNotification and can successfully recieve DEV_BROADCAST_DEVICEINTERFACE messages. However, the dbcc_name field in the returned struct is always empty. The struct I have is defined as such:
[StructLayout(LayoutKind.Sequential)]
public struct DEV_BROADCAST_DEVICEINTERFACE
{
public int dbcc_size;
public int dbcc_devicetype;
public int dbcc_reserved;
public Guid dbcc_classguid;
[MarshalAs(UnmanagedType.LPStr)]
public string dbcc_name;
}
And I'm using Marshal.PtrToStructure on the LParam of the WM_DEVICECHANGE message.
Should this be working?
Or even better... Is there an alternative way to get the name of a device upon connection?
EDIT (02/05/2010 20:56GMT):
I found out how to get the dbcc_name field to populate by doing this:
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]
public struct DEV_BROADCAST_DEVICEINTERFACE
{
public int dbcc_size;
public int dbcc_devicetype;
public int dbcc_reserved;
public Guid dbcc_classguid;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst=255)]
public string dbcc_name;
}
but I still need a way to get a "Friendly" name from what is int dbcc_name. It looks like the following:
\?\USB#VID_05AC&PID_1294&MI_00#0#{6bdd1fc6-810f-11d0-bec7-08002be2092f}
And I really just want it to say "Apple iPhone" (which is what the device is in this case).
