WinForm的2种活动页截屏打印方法

 这个程序我做了3天，主要是用来将WINFORM的当前活动页打印出来，2种方法完全不一样，一种是没边框的一种是有边框的。如图

有横向和从向打印，全是用代码写称的（随便带了2种最新的IP获得方法，NET2.0我们都不用原来旧的方法）

源代码如下：

    /// <summary>
    /// FormPrint
    /// 窗体打印
    ///
    /// 修改纪录
    ///
    ///     2007.07.31 版本：1.5 JinGangBo  新增获得本地IP地址与通过域名获得IP地址
    ///     2007.07.30 版本：1.4 JinGangBo  新增设置打印按钮功能。
    ///     2007.07.27 版本：1.3 JinGangBo  实现打印设置，修改横向打印，新增了焦点和ＥＳＣ，界面排布修改
    ///     2007.07.27 版本：1.2 JinGangBo  实现横向打印和纵向打印，打印预览最大化，及自动调及100%，及直接打印。
    ///     2007.07.26 版本：1.1 JinGangBo  代码修改与整理
    ///     2007.07.26 版本：1.0 JinGangBo  使用2种方法进行了窗体打印

这里是全部的代码，我想这个不难吧，有什么不懂的可以问我，这个程序我已经放在网上了，如果各位想下的话可以点击这个地址http://download.csdn.net/down/232641/wudiwushen
