Once the help table for an application has been created, the application must pass this help table to IPF and create a help instance, using the WinCreateHelpInstance() function. This function is shown in Figure "WinCreateHelpInstance() Function".
The WinCreateHelpInstance() function is normally called from an application's main routine, immediately after creating the application's main window, but before entering the message processing loop.
The WinCreateHelpInstance() function creates the application's main help window, which is initially invisible, and passes appropriate information to that window to enable the specified help library to be loaded and access to be obtained to required resources. See Main Help Window.
