与C＃和托管C ++之间的C ++ HWND？ [英] C++ HWND to and from C# and Managed C++?

问题描述

如何在C＃和托管C ++之间传递C ++ HWND？

How can I pass a C++ HWND to and from C# and Managed C++?

推荐答案

好像你可以使用void *：


C＃：

MyMethod（this.Handle.ToPointer（））;


C ++：

public：

void MyMethod（void * handle）

{

HWND l_wnd（句柄）;

....

}


然而，这似乎需要unsafe关键字，并且代码是

编译的/ unsafe参数。但是2，我已经找到了关于如何添加这个编译器选项的描述（例如
http://forums.microsoft.com/MSDN/Sho...22815&SiteID=1 ）会谈

关于配置属性下的Build子文件夹。我有：一般，

调试，C / C ++，链接器，清单工具，资源，XML文档生成，

浏览信息，构建事件，自定义构建设置和Web部署。

没有什么叫做Build。我在哪里可以找到这个设置？


也许这不是最好/最简单的方法。如果我能被告知这件事，我会感激的。

Seems like you could use a void*:

C#:
MyMethod(this.Handle.ToPointer());

C++:
public:
void MyMethod(void* handle)
{
HWND l_wnd(handle);
....
}

However, that seems to require the unsafe keyword and that the code is
compiled with the /unsafe parameter. However 2, the descriptions I have found
about how to add this compiler option (e.g.
http://forums.microsoft.com/MSDN/Sho...22815&SiteID=1) talks
about a Build subfolder under Configuration Properties. I have: General,
Debugging, C/C++, Linker, Manifest Tool, Resources, XML Document Generation,
Browse Information, Build Events, Custom Build setup, and web deployment.
Nothing called Build. Where do I find this setting?

Perhaps this is not the best / simplest way to do it. Then I would
appreciate if I could be told this.

What I really want to do is to pass a C# equivalent to the HWND structure in
C++ and pass it as a pointer to a HWND in managed C++. I need to get this
window handle to a third party unmanaged C++ function to assign the third
party software to render video onto this window.
