Tricky!! VB.NET counterpart of CLSIDFromProgID and CoCreateInstance

[Stephan Pilz]

Hello, I have some (more than once) COM-Servers (in different DLL's) and each of them implements the same Interface. Only what I know is the InterfaceName and the ProgID of the COM-Server. How can I instanciate a COM-Object in VB.NET with this informations? I C/C++ it looks like:

HRESULT hr = CLSIDFromProgID (ProgID), &clsid);
hr = CoCreateInstance (clsid, NULL, CLSCTX_INPROC_SERVER, IID_IInterfaceName, (void **) &m_pCOMSmartPtr);

               \\\\\\|///
             \\\\  - -  //
              (  @ @  )

Does something like this work for you?

Dim t As Type = Type.GetTypeFromProgID("_progID_")
Dim retVal As Object
retVal = Activator.CreateInstance(t)
