Bui,

>Aerror() return has no error.

Here's some relevant code from one of my working classes:

lnRetVal = SQLExec( this.mnHandle, pcSQL )

if ( lnRetVal < 0 )
   * bad SQL command
   public gaError[1]
   aerror( gaError )
   MessageBox( "Bad SQL command, check gaError for more information" )
endif
