<Animation Duration>: Optional integer

Duration of animation in hundredths of a second. This parameter can correspond to:
an integer corresponding to the number of hundredths of a second,
a Duration variable,
Versions 23 and later

the duration in clear ('1cs' or '10 ms' for example).
We recommend that you use a short duration (up to 1 second).
The application is locked as long as the animation is not over. If the user clicks or preses a key, the animation is stopped and the controls are displayed in their final status.
This parameter is ignored. No animation can be played when the control is made invisible.

Remarks

Animating a group of controls

If <Control Name> corresponds to a group of controls, the animation is played in the rectangle defined by the most top left control and by the most top right control.

The controls that do not belong to the group of controls but found in this area will also be animated.

Special cases

ControlInvisible has no effect if the control or the group of controls is not visible.
..Visible can also be used to make the controls invisible. This property cannot be used to play an animation during this operation. In Windows Mobile and in Linux, ..Visible and ControlInvisible are equivalent.
