Connection.StillExecuting property (DAO)

Applies to: Access 2013, Office 2013

Syntax

expression .StillExecuting

expression A variable that represents a Connection object.

Remarks

Use the StillExecuting property to determine if the most recently called asynchronous Execute or OpenConnection method (that is, a method executed with the dbRunAsync option) is complete. While the StillExecuting property is True, any returned object cannot be accessed.

Once the StillExecuting property returns False, following the OpenConnection call that returns the associated Connection object, the object can be referenced. So long as StillExecuting remains True, the object may not be referenced, other than to read the StillExecuting property.

Use the Cancel method to terminate execution of a task in progress.

Example

This example uses the StillExecuting property and the Cancel method to asynchronously open a Connection object.

    Sub CancelConnectionX() 
     
     Dim wrkMain As Workspace 
     Dim conMain As Connection 
     Dim sngTime As Single 
     
     Set wrkMain = CreateWorkspace("ODBCWorkspace", _ 
     "admin", "", dbUseODBC) 
     ' Open the connection asynchronously. 
     
     ' Note: The DSN referenced below must be configured to 
     ' use Microsoft Windows NT Authentication Mode to 
     ' authorize user access to the Microsoft SQL Server. 
     Set conMain = wrkMain.OpenConnection("Publishers", _ 
     dbDriverNoPrompt + dbRunAsync, False, _ 
     "ODBC;DATABASE=pubs;DSN=Publishers") 
     
     sngTime = Timer 
     
     ' Wait five seconds. 
     Do While Timer - sngTime < 5 
     Loop 
     
     ' If the connection has not been made, ask the user 
     ' if she wants to keep waiting. If she does not, cancel 
     ' the connection and exit the procedure. 
     Do While conMain.StillExecuting 
     
     If MsgBox("No connection yet--keep waiting?", _ 
     vbYesNo) = vbNo Then 
     conMain.Cancel 
     MsgBox "Connection cancelled!" 
     wrkMain.Close 
     Exit Sub 
     End If 
     
     Loop 
     
     With conMain 
     ' Use the Connection object conMain. 
     .Close 
     End With 
     
     wrkMain.Close 
     
    End Sub
