IUIAnimationTransition::GetDuration method

Gets the duration of the transition.

Syntax


HRESULT GetDuration(
  [out] UI_ANIMATION_SECONDS *duration
);

Parameters

duration [out]

The duration of the transition, in seconds.

Return value

If the method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code. See Windows Animation Error Codes for a list of error codes.

Return codeDescription
UI_E_VALUE_NOT_DETERMINED

The requested value for the duration cannot be determined.

UI_E_STORYBOARD_ACTIVE

An application should typically call the IUIAnimationTransition::IsDurationKnown method before calling this method. This method should not be called when the storyboard to which the transition has been added is scheduled or playing.

Examples

The following shows how to get the duration of a transition.


hr = pTransition->IsDurationKnown();
if (SUCCEEDED(hr))
{
    bool fDurationKnown = (hr == S_OK); 
    if (fDurationKnown)
    {
        UI_ANIMATION_SECONDS duration;
        hr = pTransition->GetDuration(&duration);
        if (SUCCEEDED(hr))
        {        
            ...
        }
    }
    else
    {
        ...
    }
}
