IDccMan (Compact 7)
3/12/2014
This interface is implemented by Connection Manager. It allows an application some control of Connection Manager and the ability to register for connection notifications.
An application creates this interface by calling the COM CoCreateInstance function, using the CLSID_DccMan globally unique identifier (GUID), and receiving a pointer to an IDccMan interface.
Methods
The following table shows the methods for this interface in alphabetical order.
| Method | Description |
|---|---|
Registers an IDccManSink object so that it can receive connection notifications from Connection Manager. |
|

Remarks
The IDccManSink::OnLog* methods should return a value of NOERROR.
An IDccMan interface method typically returns a value of NOERROR if the method succeeds.
If a method fails, it uses the HRESULT_FROM_WIN32 macro to return an HRESULT Win32 error value.
The application can display the error by using the Win32 FormatMessage function to create the error string.
For more information about message tables, see the Win32 Programmer's Reference.
To determine whether the platform supports this interface, see Determining Supported COM APIs.
