Examples

The following code example demonstrates how to use MyTransactionVote property to create a transactional ServicedComponent.


[assembly:System::Reflection::AssemblyKeyFile("Transaction.snk")];
[Transaction]
public ref class TransactionalComponent: public ServicedComponent
{
public:
   void TransactionalMethod( String^ data )
   {
      ContextUtil::DeactivateOnReturn = true;
      ContextUtil::MyTransactionVote = TransactionVote::Abort;
      
      // do work with data
      ContextUtil::MyTransactionVote = TransactionVote::Commit;
   }

};

[Transaction]
public class TransactionalComponent : ServicedComponent
{

    public void TransactionalMethod (string data)
    {

      ContextUtil.DeactivateOnReturn = true;
      ContextUtil.MyTransactionVote = TransactionVote.Abort;

      // Do work with data. Return if any errors occur.

      // Vote to commit. If any errors occur, this code will not execute.
      ContextUtil.MyTransactionVote = TransactionVote.Commit;
    }
}

<Transaction()>  _
Public Class TransactionalComponent
    Inherits ServicedComponent
    
    
    Public Sub TransactionalMethod(ByVal data As String) 
        
        ContextUtil.DeactivateOnReturn = True
        ContextUtil.MyTransactionVote = TransactionVote.Abort
        
        ' Do work with data. Return if any errors occur.
        ' Vote to commit. If any errors occur, this code will not execute.
        ContextUtil.MyTransactionVote = TransactionVote.Commit
    
    End Sub
End Class

Remarks

When MyTransactionVote is set to Commit, the COM+ consistent bit is set to true and the COM+ context votes to commit the transaction. If MyTransactionVote is set to Abort, the consistent bit is set to false and the COM+ context votes to abort the transaction. The default value of the consistent bit is true.

The consistent bit casts a vote to commit or abort the transaction in which it executes, and the done bit finalizes the vote. COM+ inspects the consistent bit when the done bit is set to true on a method call return or when the object deactivates. Although an object's consistent bit can change repeatedly within each method call, only the last change counts.
