IInterfaceInfo.Source Property

Gets a value indicating whether the interface is the source — that is, an interface that the client listens to, rather than calls.

Namespace:  Microsoft.VisualStudio.VsWizard
Assembly:  Microsoft.VisualStudio.VsWizard (in Microsoft.VisualStudio.VsWizard.dll)

Syntax

'Declaration
ReadOnly Property Source As Boolean
bool Source { get; }
property bool Source {
    bool get ();
}
abstract Source : bool with get
function get Source () : boolean

Property Value

Type: System.Boolean
true if the interface is the source; otherwise, false.

Remarks

A source interface is an interface that communicates to the client, rather than an interface the client calls (for example, by way of connection points in C++). A server calls (or multiplexes the calls if the interface allows several clients), and the client implements the handler.

Only one interface can be marked [source] in a given coclass.
