Opening a help file (CHM, HTML or PDF)
There are several ways to open a help file: - opening a full help: used to open the help file (displays the summary).
In most cases, this is done through a menu option (e.g. "? .. Help"). - opening the help for a window or a control in the application: used to open the help file on a specific page. This page presents the different options available in the window or control.
In most cases, this operation is performed via the F1 key or via a help button specific to the window.
The help is opened by WHelp. Simply specify the name of the help file to open. The help file opens on the first page of the help defined during the compilation. For example:
WHelp("MyChmHelp.chm")
WHelp("MyHelp" + Nation() + ".chm")
Opening the help of a window or control Opening the help of a window To open the help page of a window, use WHelp and specify the identifier of the desired page. This identifier was defined when creating the help system (in the characteristics of the page). Note: To automatically create a help button that displays the page corresponding to a window, drag the help page and drop it onto the desired window. The following example opens the help page of the "WIN_Configuration_Imp" window. The identifier of this help page is set to 5.
WHelp("MyChmHelp.chm", 5)
Opening the help of a control To open the help page of a control: - Specify the number of the page associated with the control in the control description ("Help" tab, "Help number" control).
- Use WHelp associated with NumHelp to open the help page (via a help button for example).
The following example presents the code of a help button. This button opens the help page associated with the control being edited.
WHelp("MyHelp.chm", NumHelp(ControlCurrent()))
