3.7 Events
3.7.1 OnKey
 Description This event must be defined in the user program and is called by the ActiveX
®
module.
 Syntax Private Sub object_OnKey ()
 Comments To use this event, a method with the name OnKey must be defined in the user program.
This method is called by the ActiveX
®
module as soon as there is a change in the EKS
(Electronic-Key inserted /Electronic-Key removed, etc.). The user can then poll which
event has occurred in the user program (EKS_KEY_IN, EKS_KEY_OUT,
EKS_KEY_OTHER). The event OnKey with the property
KeyState=EKS_EVENT_KEYIN is triggered when there is a new Electronic-Key in the
EKS. The user can then read the data on the key from the property Data without
calling the method Read. The event OnKey with the property
KeyState=EKS_KEY_OUT is triggered on the removal of the Electronic-Key. The event
OnKey with the property KeyState=EKS_KEY_OTHER is triggered when the ActiveX
®
module detects a status. The related status number can be read in the property
LastState.
Information!
The recognition, if a key is present or not, is signalled via a network telegram (see manual of the
Electronic-Key adapter EKS Ethernet TCP/IP). The telegram is sent immediately from the key adapter
to the presently connected ActiveX
®
client after placement or removal of the key.
