    pvarFormat : Object
) : int

Parameters

index
Type: System.UInt32
[in] Specifies the index of the list item of interest.

grfFlags
Type: System.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: System.Object%
[out] Specifies a pointer to a variant where you render the data. The environment frees the variant when it is done with it.

Return Value

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

Remarks

COM Signature

From vsshell80.idl:

[C++]

HRESULT IVsObjectList2::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 calls 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 calls GetExtendedClipboardVariant when the actual paste or drop operation happens. Return a pointer to the variant in pvarFormat.
