试图解决MFC BEGIN_EVENT_MAP编译时错误

编程问答 2022-08-13

问题描述

我正在将VC ++ 6.0项目转换为Visual Studio2013。遇到此错误：

error C2440: cannot convert from const AFX_EVENTMAP *(__thiscall CCmdTargetEx::* )(void) const' to 'const AFX_EVENTMAP *(__stdcall *)(void)'

这是我的代码

BEGIN_EVENT_MAP(CDispatchAccount,CCmdTargetEx) //error locate in here
//{{AFX_EVENT_MAP(CDispatchAccount)
EVENT_CUSTOM( "SetFocus",FireSetFocus,VTS_NONE )
EVENT_CUSTOM( "KillFocus",FireKillFocus,VTS_NONE )
EVENT_CUSTOM( "Tab",FireTab,VTS_NONE )
EVENT_CUSTOM( "EditFull",FireEditFull,VTS_NONE )
EVENT_CUSTOM( "EditEnter",FireEditEnter,VTS_NONE )
EVENT_CUSTOM( "ListSelChanged",FireListSelChanged,VTS_I2   )
EVENT_CUSTOM( "ChangeAccount",FireChangeAccount,VTS_NONE )
EVENT_CUSTOM( "DropDown",FireDropDown,VTS_I2   )

EVENT_CUSTOM( "EmplEditFull",FireEmplEditFull,VTS_NONE )
//}}AFX_EVENT_MAP 
END_EVENT_MAP()

我尝试更改为静态void，但仍然收到此错误

我不知道是什么原因导致此错误，导致在VC ++ 6.0中成功编译而没有错误 错误会显示在BEGIN_EVENT_MAP行上。

我已经搜索了一下，无法解决。有人做过这种事吗？还是我的代码有错

谢谢

PS：对不起，我的英语
