Clarion comes with a built-in calendar lookup control.
This control works pretty well, but can’t be customized beyond what comes “out of the box”.
Or at least that used to be the case, before J-Cal Mini was available.
How does it work?
J-Cal Mini adds a number of tweaks and settings to Clarion’s calendar lookup control. We’re not replacing Clarion’s control, we’re adding to it.
By simply adding the J-Cal Mini template to your application, and recompiling, all of your calendar lookups will change, as shown to the right.
You then have the ability to choose a theme (other than the green theme shown here), or to specify your own colors for practically every aspect of the calendar window. This lets you match the calendars to your own application design.
You can hide buttons, shorten the month name so it fits properly, set the colors and fonts to match those used in the rest of your APP. You now have full control.
How hard is this to implement?
Drop it in, recompile, and wait for your customers’ compliments. Or tweak the calendars until they look, fee and behave exactly as you’d like it to.
No fuss. No need to change any existing code.

Frequently Asked Questions
J-Cal Mini
Replacing Clarion's default calendar lookup control with the J-Cal Mini calendar is as simply as adding the global extension template and recompiling. But what if you're using a hand-coded project?
In hand-coded projects, simply replace references to Clarion's "CalendarClass" with our "CalendarClassSOL" instead.
For example, this line of code...
Calendar1 CLASS(CalendarClass)
... will become ...
Calendar1 CLASS(CalendarClassSOL)

DebugView is a free application that you can download from Microsoft, which enables you to view debug output from our products. This can be very helpful in tracking down problems.
By default, our products do not generate debug messages, so you will not see anything in DebugView. To enable debug messages, simpy tick the "Send messages to DebugView" option found on each of products' Global Extension Templates, as shown below.

Once you have turned on the "Send messages to DebugView" option, recompile and run your APP. You should then see messages appearing in DebugView.
