        index:uint32 * 
        grfFlags:uint32 * 
        pcfFormat:VSOBJCLIPFORMAT[] *

    index : uint, 
    grfFlags : uint, 
    pcfFormat : VSOBJCLIPFORMAT[], 
    pvarFormat : Object
) : int

Parameters

index
Type: UInt32

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

grfFlags
Type: UInt32

[in] Specifies multi-selection. Values are taken from the _VSOBJCFFLAGS enumeration.

pcfFormat
Type: array<Microsoft.VisualStudio.Shell.Interop.VSOBJCLIPFORMAT[]

[in] Specifies a VSOBJCLIPFORMAT structure defining the format requested.

pvarFormat
Type: Object%

[out] Specifies a pointer to a variant where you render the data. The environment will free the variant when it is done with it.

Return Value

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

Remarks

COM Signature

From vsshell.idl:

HRESULT IVsObjectList::GetExtendedClipboardVariant(
   [in] ULONG Index,
   [in] VSOBJCFFLAGS grfFlags,
   [in] const VSOBJCLIPFORMAT *pcfFormat,
   [out] VARIANT *pvarFormat
);

When the user requests a copy and paste of drag-and-drop operation on an item in your object list, the environment will call EnumClipboardFormats to see which formats your list supports. If the format is a composite format, as indicated by a flag in the pcfFormat parameter, the environment will call GetExtendedClipboardVariant when the actual paste or drop operation happens. Return a pointer to the variant in pvarFormat.
