In addition to the manipulations explained in the video, you should also note that:
4D 4D uses the ALERT command to display messages.
You’ll quickly notice that it is often necessary to update messages with additional information.
Keeping in mind future applications, you will set up a customizable form that will replace the ALERT command and display more personalized messages, where you may (or may not) authorize the copying of error messages.
Also remember that this alert dialog is a separate form. So it can contain:
- several pages
- a tab
- buttons
- arrays
- as well as anything else that seems necessary.
You can even send an automatic e-mail to the Help service containing the following information:
- about the user
- the machine
- the date
- the time
- the error message
- and so on.
- Or you can just record this information in a log file that customer service can access..
You can also set up the form so that:
- you can show or hide a particular button
- you can add a URL that you can click to access on-line help
- you can choose the message language
- you can configure messages based on a table filled in by the user
- and so on.
Once you get the hang of it, the sky is the limit.
