═══ 1. Help for Caption Sample Application ═══

Welcome to MMPM/2's sample captioning system.  We call it our sample captioning 
system because we've provided it, source code and all, as an example of one way 
to implement captioning with MMPM/2.  The system can be used as it's provided, 
or it can be modified to suit your specific needs. 

This sample captioning system is made up of three parts.  The first part of the 
system is the Caption Creation Utility.  This allows you to synchronize an 
audio file with a text file.  The second part of the system is the Caption DLL. 
This DLL provides three api's that allow an application to display, manage, and 
hide a caption window.  The third part of the system is this application, the 
Caption Sample Application.  It shows programmers how to use the three api's 
provided by the Caption DLL in order to display a caption window in an 
application. 

Select the Play push button to start playing the audio file. If MMPM/2's 
caption flag is selected (in the Setup applet) then a caption window will be 
displayed in the application's window as the audio file plays. While the audio 
file plays, the text in the caption window will scroll in syncronization with 
the audio file. 

Select the Stop push button to stop playing an audio file. If the caption 
window was displayed while the audio file was playing, then it will be hidden 
when the audio file stops. 

Select the Pause push button to pause the playing of an audio file. To resume 
playing the audio file, select the Pause or Play push button. 

Select the Rewind push button to stop the audio file and seek to it's 
beginning. 

The Audio position control provides a graphic display of the current position 
of the audio file.  To change position in the audio file, drag the slider bar 
or select the buttons at the left end of the slider. 

Adjust the audio volume of the currently loaded audio file by using the Volume 
control. 

The caption window may be dragged around the application's window. To 
accomplish this, click button one while the mouse is over the caption window, 
drag the window to the desired location and release the mouse button. 

Select the Options menu to configure the captioning system.
