// 
// The code contained in this file will assist you in integrating 
// DynaHelp onto your web site.  These functions all essentially
// invoke DynaHelp.
//

// Displaying DynaHelp
//
// There are three ways of displaying DynaHelp; in a new browser window, in an
// existing or embedded frame and in a popup window. The new window model displays 
// DynaHelp in a newly created browser window.  The embedded model displays DynaHelp 
// in an existing frame (default is self).  The popup model displays DynaHelp in a 
// small popup window with a decorated edge.  The popup model is only available to 
// IE4 and better (others see a newly created browser window).
//
// To display DynaHelp in a new window, use the plain function calls
// To display DynaHelp embedded, use the xxxEmbedded function calls
// To display DynaHelp in a popup window, use the xxxPopup function calls
//

// Invoking DynaHelp
//
// There are two methods of invoking DynaHelp; with a context id and by specifying a url.
// If you use a context id, the target of that id can be dynamically changed at runtime
// using DynaHelp Author.  This is the recommended method for accessing Help topics.
// Invoking DynaHelp using a standard url allows you to view any content within the
// DynaHelp customer assistance center.   The url method is static, however, and these
// links cannot be changed without changing the call.
//
// To invoke DynaHelp using a context id, use the DynaHelpContext calls
// To invoke DynaHelp using a standard url, use the DynaHelpUrl calls
//

// Argument Description:
// 
// strServer		- The DNS of your DynaHelp server (ie: 'www.help.com').  This is the only
//                    required parameter to any call.
// strContextId		- The context id.  Should describe where on your site the link is.
//					  (ie: 'Shipping_Form')
// strURL			- Any url that you want displayed in the DynaHelp frame.
// strFrameName		- The name of the frame to display DynaHelp in.
// strWindowId		- The name of the DynaHelp window to be displayed.  These are authored
//                    by DynaHelp Author.
// strTransactionID - You can pass DynaHelp a transaction ID that it will use to track this 
//      			  request with.
// strSessionID		- You can pass DynaHelp a session ID that it will use to track this 
//      			  request with.
// strCustomerID	- You can pass DynaHelp a customer ID that it will use to track this 
//      			  request with.
// strAppData		- You can pass DynaHelp some custom data that it will use to track this 
//      			  request with.
//

// Function Samples:
// 
// HTML code to reference the 'DynaHelp.js' file. 
//	1, if this this script name is Dynahelp.js you need not specify name tag

//	3, support name="dynahelp", Name="Dynahelp", NAME="Dynahelp"
// 
//   <SCRIPT LANGUAGE="JavaScript" NAME="DynaHelp" SRC="/ScriptsPath/DynaHelp.JS"></SCRIPT>
// 
// Display DynaHelp in a new window by a context id
// 
//   <A HREF="http://www.help.com/dynahelp/dynahelp.dll?ctxid=ctx101" TARGET="_blank"
// 
// 			ONCLICK="return DynaHelpContext( 'www.help.com', 'ctx101' );">Hyperlink Text</A>
// 
// The above example demonstrates the context id call only. Please refer to the Help for more information and examples.
