|Counter Application Components|
Counters are quite simple application components. Usually a counter is
incremented whenever it appears on a page. At the same time the counter
displays its current value. So the simplest way to use a counter is to just
put it on a page. (Tutorial)
Additionally you can use the CounterSummary component to show
summary information about all the counters on your Web site. In this scenario
you might want to hide the counters (by placing a check next to the
Hidden checkbox of the counter component).
If you don't like the layout of the CounterSummary
component, you can create your own version. You can also use
the counter component to display the current value
of a counter (without incrementing) by placing a check next to the
Frozen checkbox. Alternatively, using the database
components, you can address the Webcounter relation in the
Each counter has a name. The name is shown in the summary
display and it is used to identify the counter in the
database. By default the name a counter is the URL of the
current page, but it's better to specify a name that
describes the counter's purpose. An advantage of specifying
a name other than the URL is that you can use the
name to place the same counter on different pages
(e.g. if the pages in your Web site are available in
more than one language).
You can also use counters to count certain events, by
placing counters inside of conditional components
or using counters in your heitml programs.
In this case the counter increments only if certain conditions
Display a Web counter. Normally the Web counter increments
by one with every access of the page and the current
counter value is shown. However the counter can be frozen
or be hidden by giving several options.
|Frozen||Checkbox ||By checking this box the counter can be frozen.
It will no longer increment. |
|Hidden||Checkbox ||By checking this box the counter can be hidden.
It still increments in the background, but does
not show up. |
|Name||String(15) ||This is normally empty. You can
use it to place the same counter on two different pages, e.g.
hidden and incrementing on one page and visible and frozen on
another. In this case use the same counter name on all these pages.
Displays a table of all Web counters and their values.
If no name is given all counters are displayed.
If a name is given all counters that contain this name
as a substring are shown.
If name contains a "&" then the name is used as a like predicate
|Name||String(15) ||This is normally
You can use it to select which counters are shown.
|Clearbuttons||Checkbox ||Display buttons that can be used to clear
the counters. |
