Jereon,

What are you connecting to and which ODBC drivers are you using to do the connection. VFP is only telling you that the ODBC driver refused to make that setting for you. Are you sure the ODBC driver supports synch and asynch, that is the ODBC driver you are connecting to, not the VDFP driver.
