Enumerate the various injected sources contained in the data source.

Syntax

IDiaEnumInjectedSources : IUnknown

Methods in Vtable Order

The following table shows the methods of IDiaEnumInjectedSources.

Method	Description
IDiaEnumInjectedSources::get__NewEnum	Retrieves the IEnumVARIANT Interface version of this enumerator.
IDiaEnumInjectedSources::get_Count	Retrieves the number of injected sources.
IDiaEnumInjectedSources::Item	Retrieves an injected source by means of an index.
IDiaEnumInjectedSources::Next	Retrieves a specified number of injected sources in the enumeration sequence.
IDiaEnumInjectedSources::Skip	Skips a specified number of injected sources in an enumeration sequence.
IDiaEnumInjectedSources::Reset	Resets an enumeration sequence to the beginning.
IDiaEnumInjectedSources::Clone	Creates an enumerator that contains the same enumeration state as the current enumerator.

Remarks

Notes for Callers

This interface is obtained by calling the IDiaSession::findInjectedSource method with the name of a specific source file or by calling the IDiaSession::getEnumTables method with the globally unique identifier (GUID) of the IDiaEnumInjectedSources interface.

Example

This example shows how to obtain (the GetEnumInjectedSources function) and use (the DumpAllInjectedSources function) the IDiaEnumInjectedSources interface. See the IDiaPropertyStorage interface for an implementation of the PrintPropertyStorage function. For an alternative output, see the IDiaInjectedSource interface.
