// The Helper function for WebHelp Context Sensitive Help

//     Syntax:
//     function RH_ShowHelp(hParent, a_pszHelpFile, uCommand, dwData)
//
//     hParent
//          Reserved - Use 0
//   
//     pszHelpFile
//          WebHelp: 
//               Path to help system start page ("http://www.myurl.com/help/help.htm" or "/help/help.htm")
//               For custom windows (defined in Help project), add ">" followed by the window name ("/help/help.htm>mywin")
//
//          WebHelp Enterprise: 
//               Path to RoboEngine server ("http://RoboEngine/roboapi.asp")
//               If automatic merging is turned off in RoboEngine Configuration Manager, specify the project name in the URL ("http://RoboEngine/roboapi.asp?project=myproject")
//               For custom windows (defined in Help project), add ">" followed by the window name ("http://RoboEngine/roboapi.asp>mywindow")
//
//     uCommand
//          Command to display help. One of the following:
//                    HH_HELP_CONTEXT     // Displays the topic associated with the Map ID sent in dwData
//											if 0, then default topic is displayed.				
//               The following display the default topic and the Search, Index, or TOC pane. 
//               Note: The pane displayed in WebHelp Enterprise will always be the window's default pane.
//                    HH_DISPLAY_SEARCH 
//                    HH_DISPLAY_INDEX
//                    HH_DISPLAY_TOC
//
//     dwData
//          Map ID associated with the topic to open (if using HH_HELP_CONTEXT), otherwise 0
//
//     Examples:
//     <p>Click for <A HREF='javascript:RH_ShowHelp(0, "help/help.htm", 0, 10)'>Help</A> (map number 10)</p>
//     <p>Click for <A HREF='javascript:RH_ShowHelp(0, "help/help.htm>mywindow", 0, 100)'>Help in custom window (map number 100)</A></p>
