Difference between Wait and Synchronization in QTP

Hey folks,

Common difference between Wait and Synchronization, I try to describe here. If any more you found  add in comment, so I can also learn something new.

Wait (20)

Wait statements instruct QuickTest to wait a specified amount of time before proceeding to the next step.

At same place if you’re giving synchronization point and mention 20 seconds to wait and that wait is not mandatory. Whenever the given condition becomes true below 20 seconds

then QTP immediately goes to the next step without wait for 20 seconds.

'Writing own synchronization Point

Timeout=100

For Time=1 to Timeout

       Propval=window("Flight Reservation").WinButton("Delete Order").GetROProperty("enabled")

          If Propval=true Then

                   Exit for

          else

                   wait(1)

          End If

Next

Sync method is only available for Web.
