set event last run time to never

[Fischi]

Hi, it is possible to set the last run time of an event to „never“ by script ?
I use it for events that run very rarely.

Regards,

The time is set as follows. The variable type is date. This means it can't be string. It could be a defined date that you can use as a trigger. You would also have to check the update for the device to not update unless values change.



From help file: Purpose

This function sets the last change time of a device. Parameters

Parameter: dvRef
Type: Integer
Description: This is the device reference ID number.

Parameter: date-time
Type: date
Description: This is the date and time to set the last change to. Returns

Return value: none Example

hs.SetDeviceLastChange(5678, Now)
hs.SetDeviceLastChange(5678, Convert.ToDateTime("1/1/13 4:00 PM"))

Hope this is helpful

He wants to change an Event Last Triggered Date, not a Device. I have been trying to find that function and had no luck. As far as I know Event info is stored in the database as a "blob", which I think must be deserialized, edited then stored again. Perhaps Jon00 or one of the other developers can answer. Here is the Event data string structure.

Mea culpa. The type of Last_Triggered is still date so no string.

I think this is how you get the event structure:

------
Function Event_Info(ByVal evRef As Integer) As strEventData Purpose

This function returns information about a single event using its Event Reference ID number. Parameters

Parameter: evRef
Type: integer
Description: This is the event reference ID number for the event you want to return information about. Returns

Return value: strEventData
Type: structure
Description: This structure is described in this section.

Yep, I found that. That will return the data as an object. The question that he needs answered is how to write it back.

I did some investigation and in HS3, I don't think you can write it back with any readily available functions/subroutines. It appears that in HS2 you could. Seems odd that you can't get the object by reference. There have been many posts of frustration on this in the forum.

My only thought on a workaround is to create a device that is a proxy for the event and use that for triggering as needed. It seems inconsistent in design to prevent modification of this when you have control of most things via script.

I wrote a script to show the behavior: hs.SaveEventsDevices only saves script created events.
