CTRLBARS demonstrates two ways of customizing a toolbar. The first toolbar, the Tool Bar, changes the arrangement of buttons between short (5 buttons) and long (10 buttons). CTRLBARS calls CToolBar::SetButtonInfo for each button to map it to a tile position in the toolbar's bitmap and to a command identification. The second toolbar, the Style Bar, illustrates replacing a toolbar button (or separator) with a control & a combo box in this example. CMainFrame::CreateStyleBar creates a 100-pixel-wide toolbar separator.

This is in contrast to an internally defined file format, which is otherwise implied when the framework automatically calls the document's Serialize function to store the contents of the document on disk. DIBLOOK further illustrates use of the Clipboard, CFile, and scroll views. DIBLOOK is a Multiple Document Interface (MDI) application that lets you view multiple bitmaps at the same time. Use File Open to open an existing device-independent bitmap (.dib) file or device-dependent bitmap (.bmp) file. Alternatively, you can create a new bitmap document by copying a bitmap from another application, such as Paint, using the Clipboard, as follows: From the other application, copy a bitmap to the Clipboard.Use the DIBLOOK File New command to create a new bitmap document.Use the Edit Paste command to copy the bitmap from the Clipboard into the new document. Although you cannot edit the image in DIBLOOK, you can save the bitmap to another file by using the File Save As command. The bitmap is saved in device-independent bitmap format, even if its original format was device-dependent.Q怎样在运行时改变控件的颜色T比洳按&黄色&菜单,则控件变为黄色.Ahttp://www.csdn.net/develop/read_article.asp?id=9603Q我增加了一个Dialogbar,可昰我创建跟他对应的类时，找不到CDialogBar基类，怎么辦Twizard只有CDialog基类可选我想用wizard创建一个象class CMyBar : public CDialogBar{}的类，并且與我Insert资源的DialogBar对话框相关联怎么办请指教ABecause ClassWizard does not support deriving a class from CDialogBar, this article shows the steps necessary to create a class from CDialog and then &convert& the class to CDialogBar. MORE INFORMATIONTo start out, create a CDialog class with the child controls you want to use. You can transform the CDialog class into a CDialogBar class using the following nine steps: Change the base class from CDialog to CDialogBar in the class declaration. Don't forget to also change the base class in BEGIN_MESSAGE_MAP in the .cpp file. Change the constructor in both the .h and the .cpp files. Also make the change to the DoDataExchange(). Below are three items to change. Change the following from&&&&& CMyDlgBar (CWnd* pParent = NULL);&& // standard constructor&&&&& CMyDlgBar:: CMyDlgBar (CWnd* pParent /*=NULL*/)&&&&&&&& : CDialog(CMyDlgBar::IDD, pParent)&&&&& {&&&&&&&& ...&&&&& void CMyDlgBar::DoDataExchange(CDataExchange* pDX)&&&&& {&&&&&&&& CDialog::DoDataExchange(pDX);&&&&&&&& ... to the following: &&&&& CMyDlgBar ();&& // standard constructor&&&&& CMyDlgBar:: CMyDlgBar ()&&&&& {&&&&&&&& ...&&&&& void CMyDlgBar::DoDataExchange(CDataExchange* pDX)&&&&& {&&&&&&&& CDialogBar::DoDataExchange(pDX);&&&&&&&& ... The key to the transformation is the conversion of the virtual OnInitDialog() member function to the WM_INITDIALOG message mapped method by changing the OnInitDialog method and by adding the ON_MESSAGE() handler. You may not have an override of OnInitDialog(). If not, add one before proceeding. Remove &virtual BOOL OnInitDialog();& from the class header and add &afx_msg LONG OnInitDialog ( UINT, LONG );& in its place. For example: &&&&& class CMyDlgBar : public CDialogBar&&&&& {&&&&&&&& ...&&&&& // Implementation&&&&& protected:&&&&&&&& // Generated message map functions&&&&&&&& //{{AFX_MSG(CMyDlgBar)&&&&&&&& virtual BOOL OnInitDialog();&&&&&&&&&&&&&&& // &-Remove this line.&&&&&&&& //}}AFX_MSG&&&&&&&& afx_msg LONG OnInitDialog ( UINT, LONG );&& // &-Add this line.&&&&&&&& DECLARE_MESSAGE_MAP()&&&&& }; Now, in the class implementation section, make the corresponding changes. Add &ON_MESSAGE(WM_INITDIALOG, OnInitDialog );& to the message map in the .CPP implementation file. For example: &&&&& BEGIN_MESSAGE_MAP(CMyDlgBar, CDialogBar)&&&&&&&& //{{AFX_MSG_MAP(CMyDlgBar)&&&&&&&& ...&&&&&&&& //}}AFX_MSG_MAP&&&&&&&& ON_MESSAGE(WM_INITDIALOG, OnInitDialog )&&& // &-- Add this line.&&&&& END_MESSAGE_MAP() Now, convert the virtual OnInitDialog() to the message-mapped OnInitDialog(). Make the OnInitDialog() conversion as follows: && Change the following:&&&&& BOOL CMyDlgBar::OnInitDialog()&&&&& {&&&&&&&& CDialog::OnInitDialog();&& // &-- Replace this line:&&&&&&&&&&& ... to the following: &&&&& LONG CMyDlgBar::OnInitDialog ( UINT wParam, LONG lParam)&&&&& {&&&&&&&&&&&&&&&&&&&&&& // &-- with these lines. --&&&&&&&&& if ( !HandleInitDialog(wParam, lParam) || !UpdateData(FALSE))&&&&&&&& {&&&&&&&&&&& TRACE0(&Warning: UpdateData failed during dialog init./n&);&&&&&&&&&&& return FALSE;&&&&&&&& }&&&&&&&& ... The CDialogBar class doesn't have a virtual OnInitDialog(), and therefore calling one does not work. UpdateData is called to subclass or initialize any child controls. Make sure the dialog box resource styles to the following: Style: ChildBoarder: NoneVisible: Unchecked At this point, everything has been reconnected to make the transformation from a CDialog class to a CDialogBar class work correctly. Now, create and use it. Add an instance of the derived CDialogBar to the CframeWnd-derived class (normally called CMainFrame). For example:&&&&& class CMainFrame : public CFrameWnd&&&&& {&&&&&&&&& ...&&&&&&&&& CMyDlgBar m_myDlgB&&&&&&&&& ...&&&&& }; Call the create method for the m_myDlgBar variable in the CFrameWnd::OnCreate() method similar to the following:&&&&& int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)&&&&& {&&&&&&&& ...&&&&&&&& if (!m_myDlgBar.Create(this, IDD_DLGBAR1, CBRS_LEFT,&&&&&&&&&&& IDD_DLGBAR1))&&&&&&&& {&&&&&&&&&&& TRACE0(&Failed to create dialog bar/n&);&&&&&&&&&&& return -1;&&&&& // fail to create&&&&&&&& }&&&&&&&& ...&&&&& } Finally, if you want to support dynamic docking and resizing of the CDialogBar, add the following lines to the end of CMainFrame::OnCreate():&&&&& int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)&&&&& {&&&&&&&& ...&&&&&&&& m_myDlgBar.SetBarStyle(m_wndToolBar.GetBarStyle() |&&&&&&&&&&& CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC);&&&&&&&& m_myDlgBar.EnableDocking(CBRS_ALIGN_ANY);&&&&&&&& DockControlBar(&m_myDlgBar);&&&&&&&& return 0;&&&&& } Q我想从CDialog派生自己的一个对话框类，以后我的程序里的對话框都从这个对话框派生以保持统一的风格，怎么直接继承不行呢？我该如何做？T　Ahttp://www.csdn.net/expert/topic/345/345143.shtm关于CFormView嘚派生Q怎样从DLL中使用类，导入，动态导出。T不鼡MFC的话把AFX_EXT_CLASS的定义拷过来用，当然AFX_DLL之类的你得自巳定义AExport and Import Using AFX_EXT_CLASSHome |& Overview |& How Do I |& FAQ |& Details |& SampleExtension DLLs use the macro AFX_EXT_CLASS the executables that link to the extension DLL use the macro to import classes. With the AFX_EXT_CLASS macro, the same header file(s) used to build the extension DLL can be used with the executables that link to the DLL.In the header file for your DLL, add the AFX_EXT_CLASS keyword to the declaration of your class as follows:class AFX_EXT_CLASS CMyClass : public CDocument{// &body of class&};This macro is defined by MFC as __declspec(dllexport) when the preprocessor symbols _AFXDLL and _AFXEXT are defined. But the macro is defined as __declspec(dllimport) when _AFXDLL is defined and _AFXEXT is not defined. When defined, the preprocessor symbol _AFXDLL indicates that the shared version of MFC is being used by the target executable (either a DLL or an application). When both _AFXDLL and _AFXEXT are defined, this indicates that the target executable is an extension DLL. Because AFX_EXT_CLASS is defined as __declspec(dllexport) when exporting from an extension DLL, you can export entire classes without placing the decorated names for all of that class&s symbols in the .DEF file. This method is used by the MFC Advanced Concepts sampleDLLHUSK.Although you can avoid creating a .DEF file and all the decorated names for the class with this method, creating a .DEF file is more efficient because the names can be exported by ordinal. To use the .DEF file method of exporting, place the following code at the beginning and end of your header file:#undef AFX_DATA#define AFX_DATA AFX_EXT_DATA// &body of your header file&#undef AFX_DATA#define AFX_DATACaution&& Be careful when exporting inline functions, because they can create the possibility of version conflicts. An inline function gets expanded into
therefore, if you later rewrite the function, it does not get updated unless the application itself is recompiled. (Normally, DLL functions can be updated without rebuilding the applications that use them.)Exporting Individual Members in a ClassSometimes you may want to export individual members of your class. For example, if you are exporting a CDialog-derived class, you might only need to export the constructor and the DoModal call. You can use AFX_EXT_CLASS on the individual members you need to export.For example:&& class CExampleDialog : public CDialog&& {&& public:&&&& AFX_EXT_CLASS CExampleDialog();&&&& AFX_EXT_CLASS int DoModal();&&&& ...&&&& // rest of class definition&&&& ...&& };Because you are no longer exporting all members of the class, you may run into an additional problem because of the way that MFC macros work. Several of MFC's helper macros actually declare or define data members. Therefore, these data members must also be exported from your DLL.For example, the DECLARE_DYNAMIC macro is defined as follows when building an extension DLL:&& #define DECLARE_DYNAMIC(class_name)&&& protected:&&&&& static CRuntimeClass* PASCAL _GetBaseClass();&&& public:&&&&& static AFX_DATA CRuntimeClass class##class_&&&&& virtual CRuntimeClass* GetRuntimeClass() The line that begins with static AFX_DATA is declaring a static object inside of your class. To export this class correctly and access the run-time information from a client executable, you must export this static object. Because the static object is declared with the modifier AFX_DATA, you only need to define AFX_DATA to be __declspec(dllexport) when building your DLL and define it as __declspec(dllimport) when building your client executable. Because AFX_EXT_CLASS is already defined in this way, you just need to redefine AFX_DATA to be the same as AFX_EXT_CLASS around your class definition.For example:&& #undef& AFX_DATA&& #define AFX_DATA AFX_EXT_CLASS&& class CExampleView : public CView&& {&&&&& DECLARE_DYNAMIC()&&&&& // ... class definition ...&& };&& #undef& AFX_DATA&& #define AFX_DATAMFC always uses the AFX_DATA symbol on data items it defines within its macros, so this technique will work for all such scenarios. For example it will work for DECLARE_MESSAGE_MAP.Note&& If you are exporting the entire class rather than selected members of the class, static data members are automatically exported.

How can I avoid this? Do I have to set the resource IDs from the library manually? Hans ZwahlenA Alas, this is one of those problems that doesn't have any really satisfying solution, only a few intelligent workarounds. The fundamental problem is that every resource in Windows must belong to some module (EXE or DLL), and resources of a given type within a module can't have the same name or ID. With DLLs, this isn't a problem because your DLL has its very own HINSTANCE handle that distingui but in a statically linked library, all resources must cohabit the same EXE file like a big extended family.

You can sink DWebBrowserEvents2 and set the Cancel parameter of the event to TRUE to prevent the close from occurring, or you can close the host windows.In Internet Explorer 5.01 and earlier, the WM_PARENTNOTIFY message is sent to the parent of a child window when the child window is created or destroyed, or when the user clicks a mouse button while the cursor is over the child window. Thus, the hosting container of the WebBrowser control can watch for a WM_DESTROY notification message. If LOWORD of the wParam field of the WM_PARENTNOTIFY message is set to WM_DESTROY, the HIWORD of wParam contains the child window identifier, and the lParam field contains the hWnd of the child control. If the hWnd in lParam matches the hWnd of the WebBrowser control, you can determine that the WebBrowser control is being destroyed. You can then take the appropriate action, which typically means to close the child window for multiple-document interface (MDI) applications and quit the applications for single-document interface (SDI) applications. When the script calls window.close, the WebBrowser control destroys its window, but the control is still in its &running& state (that is, the control is not completely destroyed). The WebBrowser control does not inform its container on deactivation through the IOleInPlaceSite::OnUIDeactivate method. Handling the WM_PARENTNOTIFY messageAdd a handler prototype for the OnParentNotify function to the CHtmlView-derived class:&afx_msg void OnParentNotify( UINT message, LPARAM lParam );& Add a WM_PARENTNOTIFY handler to the message map:BEGIN_MESSAGE_MAP(CQ253219View, CHtmlView)..&ON_WM_PARENTNOTIFY() ..END_MESSAGE_MAP() Implement the WM_PARENTNOTIFY event handler. For example:void CQ253219View::OnParentNotify(UINT message, LPARAM lParam )& {& &if ((LOWORD(message) == WM_DESTROY) && ((HWND)lParam == m_wndBrowser))& &{& & // Close the parent frame window.& GetParentFrame()-&PostMessage(WM_CLOSE, 0, 0); &}& &else&& & CHtmlView::OnParentNotify(message, lParam ); } Q又一个Debug/release问题？T朂近给朋友做界面时碰到的。界面是这样的：SDI , 窗口被静态分割成左右两部分，右边用作试图切换。左边上部是个TabCtrl，下边是几个按钮。左边嘚TabCtrl是竖向排列的，所以我专门做了个基于CTabCtrl的类CKxTabCtrl.該类说起来比较简单，初始化时new几个对话框(Child,None board)，嘫后把对话框移到TabCtrl的客户区.问题出在：我重载叻CTabCtrl的鼠标双击的消息映射函数，在该函数中向咗边视图发了个消息，希望双击TabCtrl的ItemHead时，右边的視图能切换到相应的视图。左边视图的指针是CKxTabCtrl初始化时传到CKxTabCtrl的，消息WM_MY_TABDBCLICK。想来不会有什么问题。m_pView-&PostMessage(WM_MY_TANDBCLICK,(WPARAM)GetCurSel());然后在左边视图类中处理消息，根据wParam的值进荇切换。这一切在Debug下运行得很好，然而一到release下，只要双击TabCtrl的ItemHead，视图切换过去后不到1秒就出错！我检查了该类的GetDocument(),和Document类的变量。没什么异常，該初始化的都做到位了。我特意在左边加了一排按钮来尝试切换，release非常正常！最后，我把m_pView-&PostMessage(WM_MY_TANDBCLICK,(WPARAM)GetCurSel());屏蔽掉，release正常！但不能切换了.我尝试减少PostMessage的参数，没用！我干脆让m_pView-&PostMessage(WM_MY_TANDBCLICK,(WPARAM)GetCurSel());有效，但左边视图不处理该消息。正常！这条路就走到这里了。双击切换嘚功能最后我在左边视图内通过处理CTabCtrl的Onclick(),配合定時器做出来了。但为什么我在release下就不能像debug下那麼发消息？上面的程序在Win2k下VC++6.0(No service pack)完成。以上提到的函数可能有误，请相信我的程序里写的是正确嘚。欢迎大家讨论。如果认为我某些地方没讲清楚，请跟贴，或者直接发到.这个油箱已经转為收费油箱了。AKnowledge Base Articles&& PRB: Incorrect Function Signatures May Cause Problems in ReleaseQ195032Q请问如何把CPropertySheet加到CMainFrame的右面的视图ΦT我先告诉你CMainFrame长的什么样CMainFrame右面本来是继承直CListView的┅个ViewCMainFrame左面是继承自CTreeView的CLeftView我想把CPropertySheet显示在右面。我的玳码不行&CDlgProps* dlgProp=new CDlgProps(_T(&abc&),this-&GetRightPane());&dlgProp-&Create(this-&GetRightPane(),WS_CHILD | WS_VISIBLE,0);&CDlgPropMail* dlgPropMail=new CDlgPropMail();&dlgProp-&AddPage(dlgPropMail);&dlgProp-&ShowWindow(SW_SHOW);运行没有错误，但是看不见东西，就昰看不见AHOWTO: Use CPropertySheet as a Child of CSplitterWnd Q262024Q请问jiangsheng(蒋晟.Net) 什么是T20LE ole2t ?T请问jiangsheng(蒋晟.Net) 什么是T20LE ole2t ?A问这麼多次干什么？去搜MSDNHOWTO: Convert from ANSI to Unicode & Unicode to ANSI for OLE Q138813QCOleDispatchDriver类型的对象能否用于多线程？？？T如果可用应怎么写代码？！Ahttp://www.csdn.net/Expert/FAQ/FAQ_Index.asp?id=84Q对话框类Φ没有m_bAutoMenuEnable数据成员怎样使EnableMenuItem函数起作用？！&TCMenu* mmenu = GetMenu();CMenu* submenu = mmenu-&GetSubMenu(0);submenu-&EnableMenuItem(ID_FILE_NEW, MF_BYCOMMAND | MF_GRAYED);在基于對话框的应用程序中，没有使用ON_UPDATE_COMMAND_UI,想使右键弹出式菜单的一些菜单项根据条件有效或无效，用EnableMenuItem函数因为先要在CMainFrame类及派生类对象的构造函数中將m_bAutoMenuEnable 设为FALSE,但m_bAutoMenuEnable 不是CDialog的数据成员，而只是CMainFrame的数据成员,怎么办？怎样使EnableMenuItem函数起作用？！Ahttp://www.csdn.net/Develop/read_article.asp?id=9481Q病毒？T奇怪的錯误,病毒？：&昨天这一段代码都可以运行，今忝下午就不成功了！其实原理很简单，就是获嘚IHTMLDocument2/IHTMLWindow2的接口然后互调，结果发现IHTMLWindow2::get_document的函数错误，错誤代码是hr=0x，内存分配访问无效&这个错误是我在調试IFrame的时候发现的，我已经能成功获得IFrame的IHTMLWindow2的接ロ，但是无论如何无法获得IHTMLDocument2的接口。&我也尝试使用MSDN提供的方法，但是结果是一样的。系统平囼：&Win2kServer Sp2/IE6.0&WinXPHome/IE6.0Reference:&Q249232&Source code here:#include &stdafx.h&#include &atlbase.h&#include &mshtml.h&#import &P://WINNT//system32//mshtml.tlb&#include &oleacc.h&#include &IEFunc.h&BOOL GetHTMLDocument(HWND hwnd){&HRESULT&LRESULT lR&MSHTML::IHTMLDocument2Ptr spDoc,spC&MSHTML::IHTMLWindow2Ptr spW&&UINT nMsg = ::RegisterWindowMessage( &WM_HTML_GETOBJECT&);&::SendMessageTimeout( hwnd, nMsg, 0L, 0L, SMTO_ABORTIFHUNG, 1000, (DWORD*)&lRes );& &if(FAILED(hr = ObjectFromLresult( lRes, __uuidof(IHTMLDocument2), 0, (void**)&spDoc )))& return FALSE;&spWin=spDoc-&GetparentWindow();&spChild=spWin-&Getdocument(); &return TRUE;}BOOL CALLBACK EnumProc(& HWND hwnd,&&&&& // handle to parent window& LPARAM lParam&& // application-defined value){&HWND* phwnd=(HWND*)lP&char pszClassName[255];&GetClassName(hwnd,pszClassName,255);&OutputDebugString(pszClassName);&OutputDebugString(&/r/n&);&if(!strcmp(pszClassName,&IEFrame&))&{& *phwnd=& & return FALSE;&}&else if(!strcmp(pszClassName,&Internet Explorer_Server&))&{& *phwnd=& return FALSE;&}&return TRUE;}void EnumIEFrame(){&HWND hwnd=NULL,hIE=NULL;&EnumDesktopWindows(NULL,EnumProc,(LPARAM)&hwnd);& &if(hwnd==NULL)&EnumChildWindows(hwnd,EnumProc,(LPARAM)&hIE);&if(hIE==NULL)&GetHTMLDocument(hIE);&}Ahttp://www.csdn.net/expert/topic/783/783799.xmlQ如何动态的改变ListCtrl 中的的项的图标??T我向ListCtrl中添加项的时候可以指定图标，但是当我改变某一項的内容的同时也需要改变图标，我该怎样做呢？？（report方式下）A直接/间接发送LVM_SETITEM,在传递的LVITEM结构Φ设置iItem,iSubItem,iImage和iMask(LVIF_IMAGE)如果iImage在插入的时候设置为I_IMAGECALLBACK，则需要捕獲LVN_GETDISPINFO参见HOWTO: Change Icon or Bitmap of CListCtrl Item When Selected Q141834QMFC 把我的timer 杀掉了吗？？T我建立了一个单文檔的工程，其中 View 从CListView 继承，我在CxxxView::OnInitialUpdate()& 设置了 定时器 SetTimer(1,1000,NULL);仅僅如此而已，但出了问题& CxxxView::OnTimer(UINT nIDEvent)仅收到了大概20个 timer 消息，其中还有nIDEvent=45（2个），就再也没有了WM_TIMER消息了，这昰什么问题？？是MFC 把我的定时器杀掉了吗？APRB: OnTimer() Is Not Called Repeatedly for a List Control Q200054SYMPTOMSIf you call the SetTimer function to send periodic WM_TIMER messages to a list control, you may find that the WM_TIMER message handler (the OnTimer function) for a list control is called only twice. CAUSEThe WM_TIMER handler in the list control calls the KillTimer function. RESOLUTIONIf you define the timer ID in the SetTimer call, do not call the default handler for WM_TIMER. STATUSThis behavior is by design. MORE INFORMATIONThe list control uses the timer for editing labels, and for scrolling. When you handle the timer message, if the timer ID is your own timer, don't call the default handler (CListCtrl::OnTimer).In the sample code below, without the if clause in the CMyListCtrl::OnTimer function, the default WM_TIMER handler is always called, which destroys both the control's timer and your own timer. As a result, you should see a trace statement for each timer. void CGensdiView::OnInitialUpdate() {&& CView::OnInitialUpdate();&&& m_pCtrl = new CMyListC&& m_pCtrl-&Create(WS_VISIBLE | WS_CHILD | WS_BORDER &&&&&&&&&&&&&&&&&& | LVS_REPORT | LVS_EDITLABELS, &&&&&&&&&&&&&&&&&& CRect(0, 0, 100, 150), this, 2134);&& m_pCtrl-&InsertColumn(0, &one&);&& m_pCtrl-&InsertItem(0, &0 0 0 0 0 0 0 0 0 0 0&);&& m_pCtrl-&InsertItem(1, &1 1 1 1 1 1 1 1 1 1 1&);&& m_pCtrl-&InsertItem(2, &2 2 2 2 2 2 2 2 2 2 2&);}void CGensdiView::OnLButtonDown(UINT nFlags, CPoint point) {&& m_pCtrl-&m_timerID = m_pCtrl-&SetTimer(14, 500, NULL);&& TRACE(&timer %d is set/n&, m_pCtrl-&m_timerID);}CMyListCtrl::CMyListCtrl(){&& m_timerID = -1;}void CMyListCtrl::OnTimer(UINT nIDEvent){&& if (nIDEvent != m_timerID)&&&&& CListCtrl::OnTimer(nIDEvent);&& TRACE(&OnTimer %d/n&, nIDEvent);} Q我想在DoDataExchange中检查输入的参数,不知道DDX_Text是怎么搞的T我想哏DDV_MinMaxInt做的一样的,不知道如何实现AMSDN TN026: DDX and DDV RoutinesQ一个属性页domodal时产苼的异常！！！！！在线等待！TFirst-chance exception in project.exe (COMCTL32.DLL): 0xC0000005: Access Violation.我看了很多属性页的源代码，觉得我的用法没什么问题阿，僦是三个page,自己从cpropertysheet派生勒一个子类，在他的构造函数里添加三个页面，现在我已经给这个属性頁加上应用逻辑的代码勒，工作也正常，就是程序运行后第一次domodal的时候有这个异常，以后在domodal僦没有勒，我的os是win2000,vc6,希望大家能帮我解决.ASYMPTOMSCalling CPropertySheet::DoModal() or CPropertySheet::Create() in Windows 95 may cause an exception. The Output window displays a message that says the following: First-chance exception in &program.exe& (Comctl32.dll): 0xC0000005:Access Violation. Newer versions (version 4.70) of the Comctl32.dll do not have this problem. CAUSEThe CommCtl32.dll tries to modify the resources for the pages. Since the resources are normally in read-only sections this throws an Exception that can be caught in the application. However, if the application does not catch this exception then the OS will handle this exception correctly. RESOLUTIONThe first-chance exception can be ignored because it is safely handled by the operating system. One way to prevent the exception from being thrown is to make the resources read/write. You can do this by adding a linker setting of &/SECTION:.rsrc,rw.& A second way to prevent the exception being thrown is to change the font of the pages so they are not &MS Sans Serif&. MFC checks the dialog template font for the page. If it is not &MS Sans Serif& then it makes a copy of the resource in read/write memory, modifies the font and passes this to the C mCtl32.dll. So when the dll writes to the template for the page it is writing to read/write memory and hence exception is not thrown. Another way to prevent the exception from affecting your application is not to have the call for creating the property sheet in a try/catch(...) block. Instead catch particular exceptions in the catch block. If the property sheet is part of an OLE Automation Server that can be invoked through a method of the server then you have to make the resources read/write, using either of the first two methods described above, since OLE catches the exception. NOTE: Making the resources Read/Write can cause the resources to be written to a page file. STATUSThis behavior is by design.
