    pvIcon : Object
) : int

Parameters

fOnOff
Type: System.Int32

[in] Set to true to turn on animation, or set to false to turn it off..

pvIcon

Remarks

COM Signature

From vsshell.idl:

HRESULT IVsStatusbar::Animation(
   [in]BOOL fOnOff,
   [in]VARIANT *pvIcon
);

You should call this method before you perform an operation that takes an indeterminate amount of time so the user has a visual representation that the operation is continuing successfully. Call the Progress method instead of Animation if definite progress for an operation can be ascertained during the operation.

Each frame in the animation is square with a size of height X height, and is displayed at five frames per second. You are responsible for destroying the bitmap of the customized filmstrip.

The pvIcon parameter must be passed both when turning on the animation and when turning it off.

Values for SBAI_Index are listed in the following table.

SBAI_Index	Value1	Description
SBAI_General	0	Standard animation icon.
SBAI_Print	1	Animation when printing.
SBAI_Save	2	Animation when saving files.
SBAI_Deploy	3	Animation when deploying the solution.
SBAI_Synch	4	Animation when synchronizing files over the network.
SBAI_Build	5	Animation when building the solution.
SBAI_Find	6	Animation when searching.

The values of SBAI_Index are taken from vsshell.idl.
