Title: Prevent touch
Post by: Phrog30 on July 25, 2017, 03:28:16 PM

I have a clean screen that has a single button that you must hold for "x" time, then the form closes.  The form is on top of the main display/parent.  If there is a button or some other control directly beneath this button on the clean screen, once the clean screen is closed and mouse released, that control event will fire.  Any nice/easy way to prevent this?

Another option is to use the ScreenCleanButton which will clear itself after the ScreenCleanTimeInterval

I don't like the timed screens.  A button hold is much better.  So, no ideas? :)

What about capture time on MouseDown event, then on MouseUp check elapsed time and close if exceeds hold time.

Code: [Select]

    Private MouseDownTime As Date
In MouseDownEvent Handler

Code: [Select]

        MouseDownTime = Now

In MouseUpEvent handler:

Code: [Select]

Dim LapsedSeconds As Integer = DateAndTime.DateDiff(DateInterval.Second, MouseDownTime, Now)
if LapsedSeconds>3 then
  '* Close the form
End if

I just added code that required the user to release mouse before exiting.  I didn't think I would like how it worked, but it's actually not bad.  Thanks for the help.
