User Requested Sample - Incrementing ID's

Hi Everyone,

We had a request at this year’s User Conference to show how build a simple incremental counter. The scenario was that there are multiple people collecting data but each collector has been given a starting range e.g. Fred: 20000 and Barney: 50000.

This range could change from day to day so the ability to change the number was also important. Using ArcPad’s input box, each user can open the map and type in their starting value and then two, one line, scripts will keep it up to date.

This sample has been written into the Edit Form (APL) rather than an applet. The reason for this is that the script is data centric and no matter what map you open with this data in, the scripts will run. Remember applets are predominantly used when you want to achieve consistent behavior whenever any map is used.

You will see three scripts in the jScript file (Poles.js):

• initiateID() – When the map opens (with the points layer in it), the input box appears for you to type in the starting ID.
• getID() – When the Edit Form is opened, the text box “NAME” is populated with the current ID
• updateID() – When you press OK on the form the ID has 1 added to it.

Download the sample from the ArcPad Resources Center.
