void ProgressChange(
    long Progress,
    long ProgressMax
);

Event DISPID


DISPID_PROGRESSCHANGE

The DISPID for this event is defined in exdispid.h. Use this value to identify the event handler when implementing IDispatch::Invoke.

Remarks

The container can use the information provided by this event to display the number of bytes downloaded or to update a progress indicator.

To calculate the percent of progress to show in a progress indicator, multiply the value of Progress by 100, and divide by the value of ProgressMax; unless Progress is -1, in which case the container indicates that the operation is finished or hides the progress indicator.
