Hi,

How can a user choose the update frequency of a widget.

if i have 3 radiobuttons in activity module with say 6hr ,12hr and 24hr. When user selects the radiobutton how can i pass the value to ConfigureHomeWidget in service module.

Please help me if possible with an example.

Regards,

John

Save the settings in a file and read them in Service_Create. In this case you can schedule the widget to update every 6 hours and skip some of the updates base on the user settings.

Another option is to manually manage the updates by using ServiceStartAt. This is a bit more complicated.

I tried to set the UpdateIntervalMinutes parameter of ConfigureHomeWidget with a variable declared as Int. But during compilation I got the error "An integer constant is expected". So this value cannot be changed at runtime?

No. This value must be constant as it is written in one of the XML files. You should use StartServiceAt if you want to control it at runtime.

Hi Erel,

Can u please show with an example how to use StartServiceAt to update widget. i tried using timer. it works fine for very short peroid of time but not for longer period. i want user to choose from options 6, 12, 24 hr. if user selects 6 it should update every 6 hrs. if 12 selected it should change from 6 to update every 12hr.

Please help me.

In this case it will be simpler to set the update widget to 6 hours and then check in your code whether 6, 12 or 24 hours passed and update the widget.
