Timed ConfirmPopup

[snicolay]

Hello,

on a user action, I need to display a ConfirmPopup to ask the user if he really wants to stop the running test, but if he doesn't answer within 5s, then I should automatically remove this popup and continue the test.

As the "ConfirmPopup" function in CVI is a blocking call, waiting for a user action, can someone help me to set up this behavior : How can I kill the ConfirmPopup box if I have no answer within 5 seonds ?

Thanks for your help.

I see no other easy way of doing what you need than designing your own message panel and use InstallPopup to install it as a modal window, next create a loop with GetUserEvent to trap button press and a time check to handle the timeout.

Otherwise you could use a separate timer callback to handle the timeout and see if calling FakeKeystroke () function can make the message popup disappear: I never attempted such a solution, though.

Thanks Roberto,

I didn't want to define a new panel for such a small thing but, yes, I think that I'll use GetUserEvent on an own defined panel, as I don't know the behavior of a fake keystroke if the user already answered and made the panel disappear.

I just hoped a more "elegant" solution could exist.

Thank you for your contribution.

This works fine. FakeKeystroke(VAL_ESC_VKEY) results in a language-independent 'No' response.

I have created a small project to show both methods to obtain a timed MessagePopup. The example using MessagePopup () creates a timer to handle the timeout; the timer is discarded immediately after the command, so that if the user actually presses the 'Ok' button then non keystrokes will be sent to the application.

Take a look at it and feel free to comment it or ask clarifications if needed.
