B4J Library Persian Date Picker View (Independent from B4XView)

Hi everybody.
This is a Persian date picker I wrote. It doesn't use B4XView and has no special requirements.
Displaying the date picker pop-up is done with code. It works as a ResumableSub.

To use it:
1. simply add "PerPicker.bas" to your project;
2. Provide its main function with a parent node and an (x, y);
3. "Wait For" it till it returns the result once the date is picked.

I've attached a very simple sample usage code with it. The top part of the code and some other parts are also commented. Refer to them for more details if needed.

UPDATE: The calendar now shows today's date by putting a black border around it.

You're welcome Behnam;) I was hoping someone else would find it useful!
I've updated the code. Now it shows today's date, as you suggested, which is very useful indeed! Maybe I'll add a today button as well, though the current view doesn't have a suitable space for it. If I ever do add it, I'll update it here.
As for the error you mentioned, it only happens when you run in DEBUG mode. In release mode, you don't even get a warning. That's strange. Maybe following Erel's suggestion would help. But I always run in release mode anyway!

Hi. I fixed your size problem by editing the perpicker module in your code. Now you can pass it a "cell_height" parameter. The cell height was 30 in the default module. You can pass a smaller number to reduce the height and make the calendar smaller. In your code, for example, I set cell height to 22, and now it fits the small form perfectly. Here's a screenshot:

and here's your edited code:
I hope this helps;)
