Connectors
Connectors provide native access to a wide variety of DBMS products, ODBC, the platform File system, Enterprise Resource Planning systems, and Transaction Processing systems.
LSX for Connectors
LotusScript® Extensions for Connectors (LC LSX) enhances the power of Notes® by extending its scripting to data outside of Notes through the use of Connectors. The programming model is independent of the individual connector. This eliminates the need to learn each individual system, while at the same time allowing experienced users to access the individual features of a specific system.

    - Chapter 1 Introduction
      This chapter provides an introduction to the LotusScript® Extension for Connectors (LC LSX) and explains the organization of this manual.
    - Chapter 2 LCConnection Class
      This chapter provides information about the LCConnection class methods and properties.
    - Chapter 3 LCCurrency Class
      This chapter provides information about the LCCurrency class methods and properties.
    - Chapter 4 LCDatetime Class
      This chapter provides information about the LCDatetime class methods and properties.
      - LCDatetime class overview
        The LCDatetime class represents a specific date and time, including time zone and daylight savings time information. A datetime value may have either its date or time component unavailable, indicated by special constant values for date (LCDTNULL_DATE) or time (LCDTNULL_TIME) components. Flags control the behavior for the existence/absence of the date or time portion. During any datetime overflow, the maximum or minimum valid datetime value is assigned in addition to the error return.
      - Syntax for HEI Scripted Activities - 3
        When writing LotusScript® Extensions (LC LSX) scripts for HCL Enterprise Integrator (HEI) Scripted activities, you must specify Dim LCSession as a named session (this becomes the default log document name). LCConnections must also be dimensioned as existing, named HEI connection documents.
      - Type DATETIME Format and Values
        The following table lists DATETIME formats and values.
      - LCDatetime Class Methods Summary
        The following table summaries LCDatetime class methods.

      - New Method for LCDatetime
        This is the constructor for LCDatetime. It initializes a new LCDatetime object.
      - Creating a Null Datetime Object
        A "null" LCDatetime value is one whose text is "". There are three ways to obtain such a value, as listed.
      - Adjust Method for LCDatetime
        This method alters a datetime by specified datetime units.
      - Clear Method for LCDatetime
        This method clears a previously set Datetime value to. This gives it the same value as a new LCDatetime created without any constructor arguments.
      - Compare Method for LCDatetime
        This method compares two Datetime values and returns the relationship.
      - Copy Method for LCDatetime
        This method makes a copy of an LCDatetime object.

        This method produces a special constant Datetime object.
      - SetCurrent Method for LCDatetime
        This method sets the Datetime value to the current system datetime, including time zone and Daylight Savings Time setting.

GetDiff Method for LCDatetime

This method gets the difference between the values of two LCDatetime objects.

Defined In

LCDatetime

Syntax

difference = lcDatetime.GetDiff (baseDatetime, Units)

Parameters


Parameter	Description
baseDatetime	LCDatetime. The datetime object to which you want to compare the lcDatetime object.
Units	Long. The units to compare. Units are in the order listed in the constructor: Year, Month, Day, Hour, Minute, Second, Hundredth, Zone, DST. Use the following constants:
	LCDTUNIT_YEAR -- Year units.
	LCDTUNIT_MONTH -- Month units.
	LCDTUNIT_DAY -- Day units.
	LCDTUNIT_WEEKDAY -- Weekday units.
	LCDTUNIT_HOUR -- Hour units.
	LCDTUNIT_MINUTE -- Minute units.
	LCDTUNIT_SECOND -- Second units.
	LCDTUNIT_HUNDREDTH -- Hundredth of second units.
	LCDTUNIT_ZONE -- Time zone units.

Return Value


Value	Description
difference	The difference between the two LCDatetime objects, in the units specified.

If the objects are incompatible for comparison (that is, if one contains only a date and one contains only a time), or if they are date-only values and you ask for a difference in units less than days, the value will be zero.

Example

Option Public
Uselsx "*lsxlc"  
Sub Initialize
  Dim Boston As New LCDateTime _
  (1998, 1, 25,  08, 50, 00, 00,  -5,  True)
  Dim Singapore As New LCDateTime _
  (1998, 1, 27, 1, 10, 00, 00, 8, False)
  Print "A flight taking off from Boston at 8:50am"
  Print "and landing in Singapore at 1:10am"
  Print "will take " & Singapore.GetDiff (Boston, LCDTUNIT_HOUR) & " hours."
End Sub

Example Output

A flight taking off from Boston at 8:50am and landing in Singapore at 1:10am will take 27 hours.
