Remarks

Browsing table control with continuous scrollbar

For a Table control with a bouncing scrollbar, ..Count returns the number of rows displayed in the Table control (which means visible) and not the number of records in the file associated with the Table control.

Array and associative array

..Count is used to:

Find out the number of elements in an array or in an associative array.
Example:

// Associative array of integers
// indexed on strings and with duplicates
aaIDPerCustomer is associative array of int
// Add the identifier of customer "A"
aaIDPerCustomer["A"] = 55
// Add the identifier of customer "B"
aaIDPerCustomer["B"] = 321
// Add the identifier of customer "A"
aaIDPerCustomer["A"] = 56

Trace("Nb elements: " + aaIDPerCust..Count)
// Displays 2 (ignores the duplicates)
Finding out the number of occurrences for an element in an associative array. This property is very useful for an associative array with duplicates.
Example:

// Associative array of integers
// indexed on strings and with duplicates
aaIDPerCustomer is associative array of int
// Add the identifier of customer "A"
aaIDPerCustomer["A"] = 55
// Add the identifier of customer "B"
aaIDPerCustomer["B"] = 321
// Add the identifier of customer "A"
aaIDPerCustomer["A"] = 56

Trace("Nb elements: " + aaIDPerCust["A"]..Count)
// Displays 1
