    The documentation says that the hContainer structure has the returned value from the following check…

    cap = New TwCapability(TwCap.FEEDERLOADED, TwOn.One, 1)
    rc = DScap(appid, srcds, TwDG.Control, TwDAT.Capability, TwMSG.Get, cap)

    the rc does succeed… but I cannot seem to find the returned value…
    any suggestions?

    The hContainer is a pointer to TW_OneValue structure you need to marshal the hContainer to TW_OneValue and read the Item member which is of boolean type this is the value you need.

    can you expound on the marshalling of the TW_OneValue object (specifically to the bool example)?

    Thanks!
