[C#] - 主窗口嵌入子窗口(绑架窗口)

来源：http://kb.cnblogs.com/a/1572530/

 

     所谓绑架就是把其他Win32程序的窗体嵌入到我们托管的WinForm中.网上已经用很多java版和 Delphi版还有WPF的.我在这里补充C#版的.
　　C# 实现窗口"绑架" 所谓"绑架"就是把其他Win32程序的窗体嵌入到我们托管的WinForm中.网上已经用很多java版和Delphi版还有WPF的.我在这里补充 C#版的.
定义需要的Win32 API.

     需要注意的是:ResizeControl()方法很重要,否则达不到我们预期的效果.
