Parameters

index
Type: UInt32

[in] Specifies the index of the list item of interest.

ppHier
Type: Microsoft.VisualStudio.Shell.Interop.IVsHierarchy%

[out] Pointer to an IVsHierarchy interface.

pItemid
Type: UInt32%

[out] Specifies the itemid of an item within the hierarchy. Values are described in VSITEMID.

pcItems
Type: UInt32%

[out] Pointer to the count of items.

Return Value

Type: Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

COM Signature

From vsshell80.idl:

HRESULT IVsSimpleObjectList2::CountSourceItems(
   [in]          ULONG           Index, 
   [out]         IVsHierarchy **ppHier, 
   [out]         VSITEMID      *pitemid, 
   [out, retval] ULONG         *pcItems
);

Return the count of items (these must be from a single hierarchy) that make up the source files for the list element at index. Also return a pointer to the hierarchy in ppHier and pitemid if requested. If there is more than 1 item, return VSITEMID_SELECTION and a subsequent call is made on GetMultipleSourceItems to get them. If there are no available source items, return VSITEMID_ROOT to indicate the root of the hierarchy as a whole.

This method applies to class view only, and must be implemented. This enables class view to act as an alternate hierarchy so that all your project level commands continue to work.
