在c ++中使用带有托管c ++和c＃的AfxBeginThread [英] Using AfxBeginThread in c++ with managed c++ and c#

问题描述

我有一个ac＃project，Managed c ++和Native c ++的解决方案。



我在本机c ++中调用了一个函数，它有

 AfxBeginThread（
 Start_new_child_process，
（LPVOID）设置，
 NULL，
  0 ，
  0 ，
 NULL 
）; 

当我尝试通过托管c ++项目从C＃项目调用本机c ++函数时，我收到此错误：



Dubug Assertation失败！< br $>


程序：... GUI.vshost.exe



文件：fdd\vctools \\ \\ vc7libs\ship\atlmfc\afxwin1.inl



行：21



使用只有C ++ Native项目的相同代码工作正常！

任何想法如何解决问题？



谢谢

决方案

我不要为通常从C＃到C做任何事情++（I只是停留100％C ++）。通常调试断言与句柄和东西有关。



查看该文件，在第21行我看到以下

 AFXWIN_INLINE HINSTANCE AFXAPI AfxGetInstanceHandle（）
 {ASSERT（afxCurrentInstanceHandle！= NULL）; 
返回afxCurrentInstanceHandle; } 

断言是你的线程没有当前实例句柄。在我看来，您需要将C＃应用程序的实例句柄设置为该线程，并看看它是如何进行的。我不明白如何做到这一点，因为我不是C＃人。



我相信这必须位于链接的DLL项目中作为多线程DLL（/ MD [d]）



我希望我能提供更多帮助

I have a solution with a c# project, Managed c++ and Native c++.

I call a function in the native c++ which has

AfxBeginThread(
               Start_new_child_process,
               (LPVOID)Setting,
               NULL,
               0,
               0,
               NULL
               );

when I try calling the native c++ function from the C# project via the Managed c++ project i get this error:

Dubug Assertation failed!

Program: ...GUI.vshost.exe

File: f"dd\vctools\vc7libs\ship\atlmfc\afxwin1.inl

Line:21

Using the same code with only the C++ Native project works fine!
Any idea how to solve the problem?

thanks

解决方案

I don''t normally do anything from C# to C++ (I just stay 100% C++). Usually debug assertions in that have to do with handles and stuff.

Looking at that file, on line 21 I see the following

AFXWIN_INLINE HINSTANCE AFXAPI AfxGetInstanceHandle()
	{ ASSERT(afxCurrentInstanceHandle != NULL);
		return afxCurrentInstanceHandle; }

The assertion is that your thread has no current instance handle. It appears to me that you need to set the instance handle of your C# application to the thread and see how that goes. It is not obvious to me how to do that since I''m not a C# person.

I believe that this must be located in a DLL project that is linked as multithreaded DLL (/MD[d])

I wish I could be more helpful
