To overlay entire forms to the TExplorerD4 control, the
simple way is to use a panel, changing it's visible property. The Panel property let the
control manage for you the showing/hiding of the panel at the right time.
For more sophisticated application, you can control the
panel (or the panels) using the OnNavigateComplete event.
In this program we don't use this property to let you see
the more sophisticated methods.
In the HTML pages you must use a special link to able the
control to send an OnCommand event.
This command prefix can be any string, but I prefer the use
of a string formatted as below:
http://<society
name>$<application><version>$cmd/
For example. when the user click on a link like this (pay
attention, is functional):
http://pragma$exam$cmd/form
the control call the OnCommand event with the string
openForm as command name.
After the command, separated by a dollar sign, you can
insert parameters. This is an example of use of parameters:
http://pragma$exam$cmd/form$open
