C#的WinForm中嵌入.exe文件

Posted 2023-03-25

我想在WinForm中加载一个.exe的可执行文件，但是我想让他嵌入一个控件中显示，而不是新打开一个窗口来显示exe文件，请问应该怎么实现这个功能呢？

这个函数setparent
函数原型：HWND SetParent（HWND hWndChild,HWND hWndNewParent）； 　　参数： 　　hWndChild:子窗口句柄。 　　hWndNewParent:新的父窗口句柄。如果该参数是NULL，则桌面窗口就成为新的父窗口。在WindowsNT5.0中，如果参数为HWND_MESSAGE,则子窗口成为消息窗口。
-------------------
你在c#里面调用就是了，父窗口句柄设置为你的那个窗口，子窗口句柄就是你说的你那个EXE文件运行后的窗口的句柄。 参考技术A 大哥，服了你，感觉你问的问题好怪！求解！ 参考技术B 试试能不能在一个面板中加载呢？追问

怎么在面板中加载啊？

追答

不好意思，这个不知道了，还没试过

参考技术C 显示exe文件?什么意思？追问

就是把exe文件打开的意思。。是另一个form的可执行程序

C#将exe运行程序嵌入到自己的winform窗体中

以下例子是将Word打开，然后将它嵌入到winform窗体中，效果如下图：

注意：该方法只适用于com的exe（如word,Excel之类），.net的编的exe就不能用这用方法嵌入到窗体中。
