推荐答案

我解决了这个问题.我改变了

lr = pMsgHook-> WindowProc(msg，wp，lp);

为此一个

lr = CallWindowProc(pOldWndProc，hwnd，msg，wp，lp);

而且效果很好

thx u

I solved the problem. I changed it

lr = pMsgHook->WindowProc(msg, wp, lp);

for this one

lr = CallWindowProc( pOldWndProc, hwnd, msg, wp, lp);

and it works perfectly

thx u

我正在使用

"EZSkin-用于构建可换肤应用程序的原始框架" EZSkin-用于构建可换肤应用程序的原始框架 [ ^ ]

看来问题在于此代码"EZSkin"声明了HookProcedure

pMsgHook-> m_pOldWndProc =
(WNDPROC)SetWindowLong(hwnd，GWL_WNDPROC，(DWORD)HookWndProc);

我正在阅读这篇文章

了解其工作原理



如果您声明从CDialog AfxMessageBox派生的类没有失败并且具有焦点，如果您声明从cezdialog AfxMessageBox派生的类失败并且没有焦点

I am using

"EZSkin - A Primitive Framework for building skinnable apps" EZSkin - A Primitive Framework for building skinnable apps[^]

It seems that the problem is this code "EZSkin" declare a HookProcedure

pMsgHook->m_pOldWndProc =
(WNDPROC)SetWindowLong(hwnd, GWL_WNDPROC, (DWORD)HookWndProc);

I am reading this article

http://xfgr.com/?u=pz1z8ocodeprojectb0iczvKBczvcppczvdMsgBoxz6axx3nPageFlowx1wFluid[^]

to understand how it works



if you declare a class derived from CDialog AfxMessageBox not fail and it has the focus, if you declare a class derived from cezdialog AfxMessageBox fail and it hasnt the focus
