Browsing table control with continuous scrollbar

In the case of an Table control file with bounce-scroll, the Count property returns the number of lines displayed in the Table control (i.e. visible) and not the number of records from the associated file to the Table control.

Array and associative array

The Property Count allows 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: " + taIDParClient.Occurrence)
    // 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
