Question

I’m trying to create an instance of the IPortableDeviceManager class with the method CoCreateInstance(..) but I cannot find the CLSID a.k.a GUID of the class.

I dived in to the Windows SDK in an attempt to find the GUID but the only thing I could find was the following line in the file PortableDeviceApi.h:

EXTERN_C const CLSID CLSID_PortableDeviceManager;

That didn’t really help me out either..

So, what am I doing wrong? Is there any way I can find out the GUID of IPortableDeviceManager? Or instantiate an instance of it?

Summarizing:

Step 1:

To start, create a new C# Console
Application project. Next select the
“Project>Add Reference …” menu
option. Click the “COM” tab in the
“Add Reference” dialog and make sure
the following items are selected and
then click OK:

PortableDeviceApi 1.0 Type Library

PortableDeviceTypes 1.0 Type Library

Step 2:

PortableDeviceApiLib.PortableDeviceManagerClass
devMgr
= new PortableDeviceApiLib.PortableDeviceManagerClass();
