Description
Checks whether the Vcl.HtmlHelpViewer Help Viewer can process the special Windows Help request.
VCL does not provide an implementation of the IHtmlHelpTester interface. Therefore, if you need to use this function, you must implement IHtmlHelpTester in your application.
ConvertWinHelp can be called by the Help Manager when it receives a WinHelp-style or HTMLHelp-style help request from the third-party designed help system to check whether it can deconstruct this help request into something meaningful for the Vcl.HtmlHelpViewer help viewer. ConvertWinHelp is used in the Vcl.HtmlHelpViewer's implementation of the System.HelpIntfs.ISpecialWinHelpViewer.CallWinHelp method.
