我试图在我的 MFC 应用程序中使用 Winform 作为视图,但我似乎无法让它工作。它编译并运行,但是在启动视图时它崩溃,表明无法创建控件:afxwinforms.inl

return CreateControl(info,dwStyle,&pt,&size,pParentWnd,nID);

有人可以在这里帮助我吗,非常感谢我目前有以下代码:

MyWinFormsView .h:

#pragma once
#include <vcclr.h>
#include <afxwinforms.h>
#include "MyViewUserControl.h"

#include "MyDoc.h"

// CMyWinFormsView view

class CMyWinFormsView : public CWinFormsView
{
    DECLARE_DYNCREATE(CMyWinFormsView)

protected:
    CMyWinFormsView();           // protected constructor used by dynamic creation
    virtual ~CMyWinFormsView();

public:
    CMyDoc* GetDocument();
    DspAnalog::MyViewUserControl^ GetControl();

public:
    virtual void OnDraw(CDC* pDC);      // overridden to draw this view
#ifdef _DEBUG
    virtual void AssertValid() const;
#ifndef _WIN32_WCE
    virtual void Dump(CDumpContext& dc) const;
#endif
#endif

你知道microsoft mfc-winform 集成示例吗?

开始的一些提示:不要在 System... 命名空间上使用 using,导致 c++/cli 有时不匹配

看例子中每个c++文件的编译器选项,有很多东西要设置(/clr等)
