How to use customized Help files and the F1 key in Visual LANSA.

Below are some points to be considered on this area.

  1. There is no way to stop F1 delivering help. When the F1 key is pressed, Windows takes control of it and delivers a WM_HELP message to Visual LANSA. This is a programmed behavior of Windows and is a pre-defined feature of the Windows desktop.
     
  2. The user could assign another key in the application to display their own help. This can be done by defining a Menu Item component, attaching it to a menu bar as an invisible item and assigning a short cut that is required for showing the help. Using the click event of the menu item, the new help could be shown.
     
  3. If the user wants to bring up help that is not defined in the LANSA Repository, they should read the LANSA for Windows help - specifically the information contained in the sections under the title "Creating LANSA Applications with LANSA" which is contained in the title "Getting Organized".
