Enter date in Prime program?

[Jase]

I hope I don't get in trouble for this, but since I've been using Chat GPT to help with my Power Query M Code and Power BI DAX (and it's really good), I thought I'd ask it your question. I just pasted in your words. Here is the answer...

Quote:The built-in date selector you mentioned in the HP Prime's software applications isn't directly accessible for use in user programs. As you've observed, the CHOOSEDATE command is available but can be slow when navigating across years because it only allows movement one month at a time. Additionally, the INPUT command doesn't offer a date field type to replicate that functionality.

However, you can create a custom date selection interface to improve the user experience. One effective approach is to use the CHOOSE command to let users select the year, month, and day separately. This method allows for quicker navigation through years and months without the limitations of CHOOSEDATE.

Here's an example of how you might implement this:

Quote:EXPORT CustomDateSelector()
BEGIN
LOCAL yearsList, monthsList, daysList;
LOCAL selectedYear, selectedMonth, selectedDay;
LOCAL date;

// Create a list of years (e.g., from 2000 to 2030)
yearsList := MAKELIST(Y, Y, 2000, 2030);

// Create a list of months
monthsList := {"January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December"};

// Let the user select the year
selectedYear := CHOOSE(selectedYear, "Select Year", yearsList);

IF selectedYear == 0 THEN
RETURN; // User canceled
END;

// Let the user select the month
selectedMonth := CHOOSE(selectedMonth, "Select Month", monthsList);

IF selectedMonth == 0 THEN
RETURN; // User canceled
END;

// Determine the number of days in the selected month
daysList := MAKELIST(D, D, 1, DAYSINMONTH(selectedYear, selectedMonth));

// Let the user select the day
selectedDay := CHOOSE(selectedDay, "Select Day", daysList);

IF selectedDay == 0 THEN
RETURN; // User canceled
END;

// Combine the selected year, month, and day into a date
date := DATE(selectedYear, selectedMonth, selectedDay);

// Display the selected date
MSGBOX("You selected: " + STRING(date));
END;

Quote:Explanation:

Year Selection: Creates a list of years within a desired range using MAKELIST. Adjust 2000 and 2030 to set your preferred range.
Month Selection: Provides a list of month names for intuitive selection.
Day Selection: Generates a list of valid days for the selected month and year, accounting for leap years with DAYSINMONTH.
Date Compilation: Uses the DATE function to combine the inputs into a single date value.
This custom interface allows users to jump quickly to any year and month without the slow, month-by-month navigation of CHOOSEDATE. While it doesn't replicate the exact calendar icon functionality, it offers a practical and faster alternative for date selection in your programs.

Alternative Approach:

If you prefer a more graphical interface, you could simulate a calendar using graphical commands, but this would require significantly more code and complexity. The method above strikes a balance between usability and implementation effort.

Summary:

The built-in date selector with the calendar icon isn't available for user programs.
CHOOSEDATE is limited in navigation speed for distant dates.
The INPUT command lacks a date field type.
Creating a custom date selector using CHOOSE for year, month, and day offers a faster alternative.
