DesignerTransactionCloseEventArgs 类

项目
08/17/2007

提供有关 TransactionClosed 和 TransactionClosing 事件的数据。

**命名空间:**System.ComponentModel.Design
**程序集:**System（在 system.dll 中）

语法

声明
<ComVisibleAttribute(True)> _
Public Class DesignerTransactionCloseEventArgs
    Inherits EventArgs
用法
Dim instance As DesignerTransactionCloseEventArgs

[ComVisibleAttribute(true)] 
public class DesignerTransactionCloseEventArgs : EventArgs

[ComVisibleAttribute(true)] 
public ref class DesignerTransactionCloseEventArgs : public EventArgs

/** @attribute ComVisibleAttribute(true) */ 
public class DesignerTransactionCloseEventArgs extends EventArgs

ComVisibleAttribute(true) 
public class DesignerTransactionCloseEventArgs extends EventArgs

备注

TransactionClosed 事件在设计器完成事务时发生。

提示

应用于此类的 HostProtectionAttribute 属性 (Attribute) 具有以下 Resources 属性 (Property) 值：SharedState。HostProtectionAttribute 不影响桌面应用程序（桌面应用程序一般通过双击图标，键入命令或在浏览器中输入 URL 启动）。有关更多信息，请参见 HostProtectionAttribute 类或 SQL Server 编程和宿主保护属性。

示例

下面的代码示例演示如何创建 DesignerTransactionCloseEventArgs。

' This example method creates a DesignerTransactionCloseEventArgs using the specified argument.
' Typically, this type of event args is created by a design mode subsystem.            
Public Function CreateDesignerTransactionCloseEventArgs(ByVal commit As Boolean) As DesignerTransactionCloseEventArgs

    ' Creates a component changed event args with the specified arguments.
    Dim args As New DesignerTransactionCloseEventArgs(commit, False)

    ' Whether the transaction has been committed:  args.TransactionCommitted

    Return args
End Function

// This example method creates a DesignerTransactionCloseEventArgs using the specified argument.
// Typically, this type of event args is created by a design mode subsystem.            
public DesignerTransactionCloseEventArgs CreateDesignerTransactionCloseEventArgs(bool commit)
{            
    // Creates a component changed event args with the specified arguments.
    DesignerTransactionCloseEventArgs args = new DesignerTransactionCloseEventArgs(commit, false);

    // Whether the transaction has been committed:  args.TransactionCommitted
    
    return args;            
}

public:
   // This example method creates a DesignerTransactionCloseEventArgs using the specified argument.
   // Typically, this type of event args is created by a design mode subsystem.
   DesignerTransactionCloseEventArgs^ CreateDesignerTransactionCloseEventArgs( bool commit )
   {
      // Creates a component changed event args with the specified arguments.
      DesignerTransactionCloseEventArgs^ args = gcnew DesignerTransactionCloseEventArgs( commit );

      // Whether the transaction has been committed:  args.TransactionCommitted

      return args;
   }

// This example method creates a DesignerTransactionCloseEventArgs 
// using the specified argument.
// Typically, this type of event args is created by a design mode subsystem.            
public DesignerTransactionCloseEventArgs 
    CreateDesignerTransactionCloseEventArgs(boolean commit)
{
    // Creates a component changed event args with the specified arguments.
    DesignerTransactionCloseEventArgs args 
        = new DesignerTransactionCloseEventArgs(commit);
    // Whether the transaction has been committed:  
    // args.TransactionCommitted
    return args;
} //CreateDesignerTransactionCloseEventArgs

.NET Framework 安全性
