Loop with user interactions

[Lukas.Doubek]

I got a dialog with 2 buttons, PLAY and PLAYSLIDESHOW

PLAY - clicking this button, i want to make some action, for example run command ---logfilewrite "hello NI"---

PLAYSLIDESHOW - here i would like to create loop, which will click every second on first PLAY button.

The problem i got is i dont know how to let the user end this loop.

Got following code

Do While Not IsKeyPressed(&H20) 
  Call KeyWait
  Call btNext.RunClick
  Call oUDI.Sleep(1000)
Loop

This is useless, because its frozen untill user press some key. I would like it to run every second, but ends only when user press ESC. This could be done, if the function "KeyWait" would have a ms parameter like Sleep command has.

Does Diadem got some pattern for creating this kind of loop?

If i comment the "KeyWait"  function, its sleeps for one second and in this one second, all diadem buttons and everything is frozen, so i cant do nothing, even stop it and needs to kill Diadem application.

Hi Lukas,

I can think of a way of doing this with Non-modal dialog box and a global variable. Non-modal dialog boxes don't stop the script,  so it could have the control to change the user variable while the code would have the loop.

Create global variable

Create & show non-modal dialog

Loop checking the variable

In dialog's control --> change the global variable
