我是个初学者,原来好好的程序,拖一个 richedit 进去后,编译可以通过,但不干活了,为什么啊?
我分太少,没办法,但我一定给

在InitInstance()中加入
if(!AfxInitRichEdit())
{
AfxMessageBox(IDP_RICHEDIT_INIT_FAILED);
return FALSE;
}

AfxInitRichEdit
全文如下:
Important If you are using a rich edit control in a dialog box (regardless whether your application is SDI, MDI, or dialog-based), you must call AfxInitRichEdit once before the dialog box is displayed. A typical place to call this function is in your program’s InitInstance member function. You do not need to call it for each time you display the dialog box, only the first time. You do not have to call AfxInitRichEdit if you are working with CRichEditView
来源: http://www.codeguru.com/cpp/controls/richedit/article.php/c2389/CRichEditCtrlEx--Replacing-RICHEDIT-control-with-RichEdit20A.htm While writing a dev notes Visual Studio plug in, I wanted the rich edit control in a dialog to understand URL's so developers could add links to sites and email addresses. After talking to "Long John", he led me to the easy way of doing it, and now I am posting the work for others. Basically this requires CRichEditCtrlEx to use the new rich edit DLL RICHED20.DLL. The first thing to do it change the window class name of the rich edit controls from "RICHEDIT" to "RichEdit20A" in the *.rc file. Next, we create a class derived from CRichEditCtrl called CRichEditCtrlEx and override the Create() method: class CRichEditCtrlEx : public CRichEditCtrl { public: CRichEditCtrlEx(); virtual ~CRichEditCtrlEx(); // ClassWizard generated virtual function overrides //{{AFX_VIRTUAL( CRichEditCtrlEx ) public: virtual BOOL Create( DWORD in_dwStyle, const RECT& in_rcRect, CWnd* in_pParentWnd, UINT in_nID ); //}}AFX_VIRTUAL // Generated message map functions protected: //{{AFX_MSG( CRichEditCtrlEx ) //}}AFX_MSG DECLARE_MESSAGE_MAP() }; Now implement the Create() method like this: Post a comment Email Article Print Article Share Articles Digg del.icio.us Newsvine Facebook Google LinkedIn MySpace Reddit Slashdot StumbleUpon Technorati Twitter Windows Live YahooBuzz FriendFeed BOOL CRichEditCtrlEx::Create(DWORD in_dwStyle, const RECT& in_rcRect, CWnd* in_pParentWnd, UINT in_nID) { if( ! ::AfxInitRichEditEx() ) { return FALSE ; } CWnd* l_pWnd = this ; return l_pWnd->Create( _T( "RichEdit20A" ), NULL, in_dwStyle, in_rcRect, in_pParentWnd, in_nID ); } This is almost exactly what is in CRichEditCtrl::Create(), except the different window class name, and the call to AfxInitRichEdit() has been changed to AfxInitRichEditEx() which first calls AfxInitRichEdit (we do not want to break the normal CRichEditCtrl). In the RichEditCtrlEx.h file, you need to add the DLL holder class and function prototype: class _AFX_RICHEDITEX_STATE { public: _AFX_RICHEDITEX_STATE(); virtual ~_AFX_RICHEDITEX_STATE(); HINSTANCE m_hInstRichEdit20 ; }; BOOL PASCAL AfxInitRichEditEx(); Now, in the source code, add the implementation: _AFX_RICHEDITEX_STATE::_AFX_RICHEDITEX_STATE() { m_hInstRichEdit20 = NULL ; } _AFX_RICHEDITEX_STATE::~_AFX_RICHEDITEX_STATE() { if( m_hInstRichEdit20 != NULL ) { ::FreeLibrary( m_hInstRichEdit20 ) ; } } _AFX_RICHEDITEX_STATE _afxRichEditStateEx ; BOOL PASCAL AfxInitRichEditEx() { if( ! ::AfxInitRichEdit() ) { return FALSE ; } _AFX_RICHEDITEX_STATE* l_pState = &_afxRichEditStateEx ; if( l_pState->m_hInstRichEdit20 == NULL ) { l_pState->m_hInstRichEdit20 = LoadLibraryA("RICHED20.DLL") ; } return l_pState->m_hInstRichEdit20 != NULL ; }

        VC/MFC社区版块或许是CSDN最“古老”的版块了,记忆之中,与CSDN的年龄几乎差不多。随着时间的推移,MFC技术渐渐的偏离了开发主流,若干年之后的今天,当我们面对着微软的这个经典之笔,内心充满着敬意,那些曾经的记忆,可以说代表着二十年前曾经的辉煌……
        向经典致敬,或许是老一代程序员内心里面难以释怀的感受。互联网大行其道的今天,我们期待着MFC技术能够恢复其曾经的辉煌,或许这个期待会永远成为一种“梦想”,或许一切皆有可能……
        我们希望这个版块可以很好的适配Web时代,期待更好的互联网技术能够使得MFC技术框架得以重现活力,……
