Display screenmask while query is opening

[cdev]

Hello,

I have a query that takes some time to open.   I would like to display a screenmask  'Data loading, please be patient ...' while the query is opening and the data is not yet available.

How do I do this ?   I had a look at the screenmask sample, but this shows how to display a screenmask with the sleep function.
