Troi Activator Plug-in Filemaker 6 conversion note

We have two types of Activator plug-ins: Troi Activator Plug-in 1.5 which uses the Classic API and Troi Activator Plug-in 3.1 (or higher) which uses the FileMaker 7 Native API. Below you find a discussion of both plug-ins.
NOTE The API is the same for FileMaker Pro 7 to FileMaker Pro 12.

NB Below we will discuss Troi Activator Plug-in 2.0, the first version to be FileMaker 7 Native, but this also applies to future versions with a higher number, for example version 3.1.

TIP Although you can use both Troi Activator Plug-in 1.5 and Troi Activator Plug-in 2.0 together when running FileMaker 7, this is not recommended. Please only use Troi Activator Plug-in 2.0 for FileMaker Pro 7 and later.

Troi Activator Plug-in 1.5 is compatible with FileMaker 7 and 8

Troi Activator Plug-in 1.5 in general does work with FileMaker Pro 7, without modification. We have found no issues with FileMaker 7 and 8.

General Issue for all Classic plug-ins with higher ASCII's

FileMaker Pro 7 has a new internal architecture, which is using Unicode for the text fields. FileMaker Pro 6 only used ASCII encoding. ALL plug-ins written for the 'classic' FileMaker 6 architecture do not receive characters that are outside this ASCII range, these characters are replaced with spaces. In general our plug-ins should be compatible as long as the text used is lower ASCII text.

The Activator Plug-in 1.5 is using the classic API, so only characters in the ASCII range will work.

Previous versions of Troi Activator

We have tested version 1.4 with FileMaker 7 and this works similar as version 1.5. We have not tested earlier versions, however this latest version has some bug fixes too, so it is strongly recommend that you use the latest version.

 

Troi Activator Plug-in 2.0 (Native FileMaker 7 API)

Troi Activator Plug-in 2.0 was created specifically for FileMaker Pro 7 to 9. Below are some considerations when converting to Troi Activator Plug-in 2.0.

New function syntax

The plug-in functions have a different syntax compared to the FileMaker 6 plug-in.

For example the Actr_GetEventInfo function has this syntax in the classic API:

External("Actr-GetEventInfo", "switches|eventID" )

The syntax in the new API looks like this:

Actr_GetEventInfo(switches ; eventID )

Note that functions look like a real function call, no longer a call to External( ). Also a hyphen "-" is no longer allowed in the function name, so the hyphens have changed to underscores "_" instead. Note too that parameters don't have to be concatenated with a pipe. Instead use a semicolon ";" to separate the parameters. Below is an example how this function would appear in ScriptMaker:

Set Field [result , Actr_GetEventInfo( switches ; eventID ) ]

TIP Function names are no longer case sensitive and will change to the correct case after you close the "Specify Calculation" dialog box.

Multiple parameters and new switches

As seen from the syntax, plug-in functions now can have multiple parameters. All functions already had a switches parameter as the first parameter, so in this plug-in this was not changed. We merged the date and time parameter into a timestamp field in the Actr_ScheduleEvent function, to make calculating easier. See the specific functions notes below for the specifics.

TIP Switches are not case sensitive.

Omitting optional parameters

When you omit an optional parameter be sure to add an extra semicolon after the last one, otherwise FileMaker 7 will show an alert that there are too few parameters in this function. For example, below we omitted the 2nd parameter at the end (eventID ). This is the correct way to do this:

Set Field [ result, Actr_DeleteEvent( "-DeleteLastTriggered" ; )]

New parameter limits

The plug-in functions now have a size limit of 1 Gb per parameter (up from the total of 64000 character limit for all parameters in FileMaker 6). The Troi Activator Plug-in 2.0 in general can handle bigger parameters.

Converting the function call

When converting FileMaker does not change the plug-in call. So after conversion you need to do this manually. Here are the global steps:

  • remove the External(" at the beginning
  • in the function name: change Actr- to Actr_, add a ( at the end.
  • split the remaining parameters: separate each with a ;

Let's for example take this Troi Activator Plug-in 1.5 call:

External("Actr-DeleteEvent", "-DeleteByID" & "|" & gEventID)

This needs to be changed to this Activator Plug-in 2.0 call:

Actr_DeleteEvent( "-DeleteByID" ; gEventID)

TIP You can just copy script or steps from the example files of the Activator download, they are all in the Activator Plug-in 2.0 format!

Specific functions notes

All functions of Troi Activator Plug-in 2.0 fully support Unicode, unless noted otherwise.

Actr_ScheduleEvent

The date and time parameter are now in 1 timestamp parameter.
