Cancels the execution of a pending Execute call.
The Cancel method is used to cancel the last pending, asynchronous call involving the Execute
method of the Command object.
The Options parameter of the Execute method must be set to either the adAsyncExecute
or adAsyncFetch constant.
Otherwise, a run-time error will be generated.
An asynchronous call returns control to the calling program before the operation is completed and allows
the execution of the code to continue.
If (objCommand.State = adStateFetching) Then
objCommand.Cancel
End If
