PHP function calculate the distance between two coordinates (latitude, longitude)

Dreamweaver Help / Server behaviors, databases, and bindings in Dreamweaver CC

by

This document addresses queries around server behaviors, the Bindings panel, and databases in Dreamweaver CC released on June 18 2013.

In Dreamweaver CC, server behaviors are available as an extension, Deprecated_ServerBehaviorsPanel_Support.zxp. After you install the extension, the server behaviors feature is enabled and extensions dependent on it work as they did previously.

In the CC release, based on your OS, you can find the extension at the locations below.

  •  Vista/Windows 7: C:/Program Files (x86)/Adobe/Adobe Dreamweaver CC/Configuration/DisabledFeatures
  •  Mac OS X: /Applications/Adobe Dreamweaver CC/Configuration/DisabledFeatures

Note:

MXP type extensions are not supported in Extension Manager CC. The MXP format has been replaced with the ZXP extension format.

An MXP extension can be converted to a ZXP extension using the “Convert MXP Extension To ZXP” tool. This tool can be found in the Tools menu in Extension Manager for CS6.

Get(FoundCount) – Filemaker functions

by

Get(FoundCount)

Purpose
Returns a number that represents the number of records in the current found set.

Format
Get(FoundCount)

Parameters
None

Data type returned
number

Description
If there are multiple windows open in the current database file, each window can have its own found count value, but results are returned for only the foreground window.
If you specify the context for the current calculation, this function will be evaluated based on that context; otherwise, it will be evaluated based on the context of the current window.
Note For information on how functions evaluate differently on the host versus the client, search the FileMaker Knowledge Base available at www.filemaker.com/kb.

Examples
Returns 7 when there are 7 records in the current found set.
