C# winform页面多进程打开exe

# AppContainer Embed an exe application into the panel control. make it feels like you own this exe application. http://www.cnblogs.com/bitzhuwei/archive/2012/05/24/SmileWei_EmbeddedApp.html <p>这是最近在做的一个项目中提到的需求，把一个现有的窗体应用程序界面嵌入到自己开发的窗体中来，看起来就像自己开发的一样（实际上&hellip;&hellip;跟自己开发的还是有一点点区别的，就是内嵌程序和宿主程序的窗口激活状态问题）。</p> <p>在codeproject找到了一篇相关的文章（<a title="Hosting EXE Applications in a WinForm project" href="http://www.codeproject.com/Articles/9123/Hosting-EXE-Applications-in-a-WinForm-project" target="_blank">http://www.codeproject.com/Articles/9123/Hosting-EXE-Applications-in-a-WinForm-project</a>），虽然可用，但是很不方便，于是重新设计编写了一个类库，用一个控件完成内嵌其它应用程序的功能。</p> <p>直接上图先：</p> <p>&nbsp;<a href="http://images.cnblogs.com/cnblogs_com/bitzhuwei/201205/201205241831233469.png"><img style="display: inline;
