Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     A Help ID is a number used to specify the help screen to be
     associated with a PWB dialog box. Functions that display dialog
     boxes have a Help ID argument in which you can specify a Help
     topic for the dialog box. You can select an unused ID number for
     this argument, then build a new PWB Help file with a matching
     topic. To add a topic to the PWB.HLP file, you must decompress
     PWB.HLP using HELPMAKE, then recompress it with your new topic.
 
     The dialog topic numbers 20000 to 29999 are reserved for user-
     defined Help. Using a number in this range guarantees that there
     will not be a conflict with a PWB Help topic, but it cannot
     guarantee that there will not be a conflict with a Help file
     defined by another extension programmer.
 
     When you specify a Help ID number, PWB searches for a Help topic
     string consisting of the ID number prefixed by "pwb.hlp!d.". For
     example, if you specify 22901 as the Help ID for your extension,
     you should create a PWB Help file with the topic "d.22901".
 
     To specify your own Help file, rahter than the PWB.HLP file use
     DoMessageBoxHelp.
