    我正在我的程序中实现一个消息传递系统。它的功能与电子邮件一样,只是它完全包含在系统中。

    我想知道是否有人看到过我可以修改的电子邮件控制模板。它将包含收件箱、消息查看和消息发送部分等内容。

    我只需将邮件的发送和接收部分重新连接到我的连接到我的表上。

    谢谢!

    我最终创建了自己的用户控件。如果有人感兴趣的话,我会把细节贴出来。

    编辑:

    好吧,我没意识到我写了这么多。如果你用这个的话,一定要相信Biff-Magriff。D 技术是.NET 3.5和亚音速3.0

    最后应该是这样。

    嗯,不能超过3万个字符…

    从上面继续。

    如果你愿意出一些钱, Telerik 有一个美好的 PanelBar 控件的外观与Outlook类似。我相信它附带的示例与他们站点上的类似于Outlook的演示应用程序是相同的,因此这可能是一种非常快速和简单的入门方法。

    史蒂夫·丹纳:

    Telerik有一个很好的panelbar控件,看起来就像Outlook。我相信它附带的示例与他们站点上的类似于Outlook的演示应用程序是相同的,因此这可能是一种非常快速和简单的入门方法。

    仅供参考,panelbar控件只是一个用户界面,它不提供消息传递功能。当然,您可以使用它使您的邮件系统看起来像Outlook,但是您仍然需要自己进行编码。
