How to create two 30 secs delay in 1000 loops routine

[JeffB]

The API GetTickCount() sounds like a good candidate to do this. There is still a case where the value will roll back to 0, but it seems appropriate for what you are doing.

Also, be careful with construction like this:

Do While Timer <> Start

This could lead to an infinite loop, the chances are very small, but I've already seen problem with that kind of validation.

Hope it helps.
