Thanks for your answer.

I'll try to explain more my problem.

I a several database query to execute and I want to pause between each query. Like that, I give a pause to the processor.

EX :

Private Sub Main    
    While (1)
         ExecuteQuery1()

         Pause

         ExecuteQuery2()

         Pause

         ExecuteQuery....
    End While
End Sub

I hope that can help to understand the problem.
thx
