npAbacCreate

Create a new instance of an Abac object and attach it to a NeoBook rectangle object. The result variable store "True" if everything is OK, or "False" if an error ocurr. In this last case the [LastError] variable store information about the error.

npAbacDestroy

Destroy a previously Abac object instance and deattach from their NeoBook rectangle. The result variable store "True" if everything is OK, or "False" if an error ocurr. In this last case the [LastError] variable store information about the error.

npAbacDestroyAll

Destroy all previously Abac objects instances and deattach from their NeoBook rectangles.

By this way, you can share one subroutine with more than one control. The button variable store one of the button "names" listed on npAbacPress, and, additionally the cbNone value.

The result variable store "True" if everything is OK, or "False" if an error ocurr. In this last case the [LastError] variable store information about the error.

Action errors subroutine

All the NeoPlugins deal with errors in the same way that NeoBook does: when the plugin found an action error the [LastError] variable store information about the error, so you can take care about this variable when execute an action.

But all the NeoPlugins also incorporate an advanced way to deal with possible action errors. You can define a subroutine named OnNeoPluginActionError in order to be executed when some action error are found and you can use this variables inside:

• [LastError] The last action error message.
• [PluginName] Store the plugin name which cause the error.

Note that this error handling subroutine are shared for all the NeoPlugins, so you no need to specify a subroutine for every plugin you use in your publication because the same subroutine are recognized and automagically used by every NeoPlugin. Below you can view a sample of this subroutine code:

:OnNeoPluginActionError
  AlertBox "NeoPlugin Error" "Error [LastError] in plugin: [PluginName]"
Return

Also note that the use of this NeoPlugins error handling subroutine is completelly optional. You can continue using the [LastError] variable as usual and even use the both methods at the same time.
