Command Execute Method Connection Execute Method Connection Object Recordset Open Method Recordset Object EVENT:  Connection::WillExecute WillExecute Source, CursorType, LockType, Options, adStatus, pCommand, pRecordset, pConnection   The WillExecute event can be fired just before a Command Execute, Connection Execute, or Recordset Open method starts to execute. This event is one of two command execution management events that can be called. The other event is ExecuteComplete.   An event is simply a subroutine that can be called automatically after a specific operation has occurred. This subroutine can contain any code that you need to run when the event occurs. The subroutine will only be called if it is included in your code. Future calls to the event subroutine can be cancelled by setting the adStatus parameter to be the adStatusUnwantedEvent constant (see table below) before the event returns.   There are eight parameters that are passed to this event.   The Source parameter is a string that contains either an SQL command or a stored procedure name.   The CursorType parameter is a long value that is one of CursorTypeEnum constants.   CursorTypeEnum constants   Constant Value Description adOpenDynamic 2 Provides a dynamic cursor adOpenForwardOnly 0 Default, provides a forward-only cursor adOpenKeyset 1 Provides a keyset cursor adOpenStatic 3 Provides a static cursor adOpenUnpecified -1 Unspecified   The LockType parameter is a long value that is one of LockTypeEnum constants.   LockTypeEnum Constants   Constant Value Description adLockBatchOptimistic 4 Multiple users can modify the data and the changes are cached until BatchUpdate is called adLockOptimistic 3 Multiple users can modify the data which is not locked until Update is called adLockPessimistic 2 The provider locks each record before and after you edit, and prevents other users from modifying the data adLockReadOnly 1 Read-only data adLockUnspecified -1 Lock type unknown   The Options parameter is a long value that is one or more of the CommandTypeEnum or ExecuteOptionEnum constants. It comes from the Options parameter of the Command Execute, Connection Execute, or Recordset Open methods.   CommandTypeEnum Constants   Constant Value Description adCmdFile 256 Evaluate as a previously persisted file adCmdStoredProc 4 Evaluate as a stored procedure adCmdTable 2 Have the provider generate a SQL query and return all rows from the specified table adCmdTableDirect 512 Return all rows from the specified table adCmdText 1 Evaluate as a textual definition adCmdUnknown 8 The type of the CommandText parameter is unknown adCmdUnspecified -1 Default, does not specify how to evaluate   ExecuteOptionEnum Constants   Constant Value Description adAsyncExecute 0x10 Execute asynchronously adAsyncFetch 0x20 Rows beyond the initial quantity specified should be fetched asynchronously adAsyncFetchNonBlocking 0x40 Records are fetched asynchronously with no blocking of additional operations adExecuteNoRecords 0x80 Does not return rows and must be combined with adCmdText or adCmdStoredProc adOptionUnspecified -1 The CommandText parameter is unspecified   The adStatus parameter defines the status of the event and is set to either the adStatusOK or the adStatusCantDeny values of the EventStatusEnum constants. Before the event returns, to prevent unwanted future firings of this event, set this parameter to adStatusUnwantedEvent, or set it to adStatusCancel to cancel the operation that fired the event.   EventStatusEnum Constants   Constant Value Description adStatusCancel 4 Cancels the operation that fired the event adStatusCantDeny 3 Cannot cancel pending operation adStatusErrorsOccurred 2 Indicates that warnings and/or errors occurred adStatusOK 1 The operation that fired the event was successful adStatusUnwantedEvent 5 The operation that generated the event cannot generate future events   The pCommand parameter is set either to the Command object that was executed or to Nothing.   The pRecordset parameter is set either to the Recordset object that resulted from the execution of the command or to Nothing.   The pConnection parameter is the Connection object that is associated with the execution.   Code (Visual Basic): ' Use the WithEvents keyword to designate that events ' can be handled by this Connection object Dim WithEvents objConn As ADODB.Connection ' Note how the object name, objConn, is incorporated into the event Sub name Private Sub objConn_WillExecute( Source As String, _    CursorType As ADODB.CursorTypeEnum, _    LockType As ADODB.LockTypeEnum, _    Options As Long _    adStatus As ADODB.EventStatusEnum, _    ByVal pCommand As ADODB.Command )    ByVal pRecordset As ADODB.Recordset )    ByVal pConnection As ADODB.Connection ) ' place any code you desire here, for example If LockType = adLockReadOnly Then    Print "The Lock Type is read-only" End If End Sub Copyright 1999-2001 by Infinite Software Solutions, Inc.
