Card Question

What would be the best way to "refresh" a card? I have a card where I am updating dropdown fields from a SQL database. When a update is done, I want to rerun the "on opencard" function which contains the statements to load my dropdown fields. Should I just close and reopen the card or can I specify a call to the "on opencard" function?

Hope I am making sense.

Hi Warren,

You can make a new handler, which contains the entire openCard handler, but with a different name. Call this handler from the openCard handler and from the handler that is supposed to refresh the card. There is no need to go to a different card and back.

Best,

Mark

Mark,

Would this be a function I create?

ie.
on opencard
call RefreshCard
end opencard

function RefreshCard
(enter code)
end RefreshCard

Thanks for your help!

Hi Warren,

No, not like that. This would be a handler of the form

Code: Select all

on handlerName
  -- do something here
end handlerName

You can call it, simply by issueing the command. You don't need to use the call command.

Best,

Mark
