随便贴贴,学过VB的人都应该知道的,不好意思。 '********************************************************************************************** ' MTS VB6 COM Component Template - by Michael Gonzalez '********************************************************************************************** '(1) You must create a reference to the Microsoft Transaction Server Type Library (mtxas.dll). ' If using Windows 2000, choose the COM+ Services Library (comsvcs.dll) instead. '(2) Set your ClassModule's MTSTransactionMode property to 2 - RequiresTransaction ' Note: ONLY use 2 - Requires Transaction if you plan on using the component with an MSDTC- ' compliant Resource Manager such as MSMQ or SQL Server - OTHERWISE, use ' 1 - No Transactions '(3) Make sure your project's Unattended Execution property is checked '(4) Make sure your project's Component Version Compatibility is set to Binary Compatibility '********************************************************************************************** ' ObjectControl implements the interface that is used by MTS when the object is ' activated and/or deactivated - this happens when you call one of the components's methods ' The ObjectControl implementation makes use of three procedures: ' 1) ObjectControl_Activate ' 2) ObjectControl_CanBePooled ' 3) ObjectControl_Deactivate '********************************************************************************************** Implements ObjectControl
