無模式對話框和Windows通用對話框

1、無模式對話框和Windows通用對話框1、利用對話框編輯器創(chuàng)立一個對話框資源2、用ClassWizard來創(chuàng)立CEx07aDialog類3、添加變量到CEx07aDialog類中IDC_EDIT1- m_strEdit14、編輯CEx07aDialog.h增加視圖指針和函數(shù)原型private:CView* m_pView;public:CEx07aDialog(CView* pView);BOOL Create();5、編輯CEx07aDialog.h并在其中定義WMGOODBYE消息ID#define WM_GOODBYE WM_USER + 5 /常量WM_USER是用戶自定義消息中可利用

2、的第一個消息6、在文件CEx07aDialog.cpp中參加無模式對話框的構(gòu)造函數(shù)CEx07aDialog:CEx07aDialog(CView* pView) / modeless constructorm_pView = pView;BOOL CEx07aDialog:Create()return CDialog:Create(CEx07aDialog:IDD);8、編輯CEx07aDialog.cpp文件中的OnOK和OnCancel的單擊響應(yīng)函數(shù)void CEx07aDialog:OnCancel() / not really a message handlerif (m_pView

3、!= NULL) / modeless case - do not call base class OnCancelm_pView-PostMessage(WM_GOODBYE, IDCANCEL);else CDialog:OnCancel(); / modal casevoid CEx07aDialog:OnOK() / not really a message handlerif (m_pView != NULL) / modeless case - do not call base class OnOKUpdateData(TRUE);m_pView-PostMessage(WM_GO

4、ODBYE, IDOK);else CDialog:OnOK(); / modal caseclass CEx07aView : public CViewprivate:CEx07aDialog* m_pDlg;10、修改ex07aView.cpp文件中的CEx07aView類的構(gòu)造函數(shù)和析構(gòu)函數(shù)CEx07aView:CEx07aView()m_pDlg = new CEx07aDialog(this);11、CEx07aView:CEx07aView()delete m_pDlg; / destroys window if not already destroyed12、在ex07aView

5、.cpp文件的虛函數(shù)OnDraw中加進一些代碼void CEx07aView:OnDraw(CDC* pDC)pDC-TextOut(0, 0, Press the left mouse button here.);13、利用ClassWizard加進CEx07aView的鼠標消息處理函數(shù)。請加進WM _LBUTTONDOWN和 WM_RBOTTONDOWN消息的處理函數(shù)，然后再按如下的代碼對 ex07aView.cpp文件中的這兩個消息處理函數(shù)分別進行編輯：void CEx07aView:OnLButtonDown(UINT nFlags, CPoint point) / creates t

6、he dialog if not created alreadyif (m_pDlg-GetSafeHwnd() = 0) m_pDlg-Create(); / displays the dialog windowvoid CEx07aView:OnRButtonDown(UINT nFlags, CPoint point) m_pDlg-DestroyWindow();/ no problem if window was already destroyed#include ex07aView.h#include ex07aDialog.h15、針對WM_GOODBYE消息加進自己的消息代碼在

7、ex07aView.cpp將以下語句行加在BECIN MESSAGE MAP I語句之后但必須將它加在AFX_MSG_MAP之外：BEGIN_MESSAGE_MAP(CEx07aView, CView)ON_MESSAGE(WM_GOODBYE, OnGoodbye)/AFX_MSG_MAP(CEx07aView)ON_WM_LBUTTONDOWN()ON_WM_RBUTTONDOWN()/AFX_MSG_MAPEND_MESSAGE_MAP()然后加進完整的消息處理函數(shù)LRESULT CEx07aView:OnGoodbye(WPARAM wParam, LPARAM lParam)/ me

8、ssage received in response to modeless dialog OK/ and Cancel buttonsm_pDlg-DestroyWindow();return 0L;16、在ex07aView.h中加人如下函數(shù)原型。將下面的語句加在DECLARE_MESSAGE_MAP()語句之前AFX_ MSC括弧對之外：/AFX_MSG(CEx07aView)afx_msg void OnLButtonDown(UINT nFlags, CPoint point);afx_msg void OnRButtonDown(UINT nFlags, CPoint point)

9、;/AFX_MSGafx_msg LRESULT OnGoodbye(WPARAM wParam, LPARAM lParam);DECLARE_MESSAGE_MAP()Windows通用對話框-CfileDialog1、用對話框編輯器創(chuàng)立對話框資源2、利用ClassWizard來創(chuàng)立CSpecialFileDialog類把名字更改相應(yīng)文件名為SpecFileDlg.h和SpecFileDlg.cpp手工將Base Class 改為CfileDialog在SpecFileDlg.h中將class CSpecialFileDialog : public CDialog改為class CSpec

10、ialFileDialog : public CFileDialog加人下面兩個公有數(shù)據(jù)成員public:CString m_strFilename;BOOL m_bDeleteAll;最后；編輯構(gòu)造函數(shù)聲明如下public:CSpecialFileDialog(BOOL bOpenFileDialog, / TRUE for FileOpen, FALSE for FileSaveAsLPCTSTR lpszDefExt = NULL,LPCTSTR lpszFileName = NULL,DWORD dwFlags = OFN_HIDEREADONLY | OFN_OVERWRITEPRO

11、MPT,LPCTSTR lpszFilter = NULL,CWnd* pParentWnd = NULL);3、在SpecFileDlg.h中用CFileDialog替換CDialog4、在SpecFileDlg.CPP文件中CSpecialFileDialog構(gòu)造函數(shù)進行編輯CSpecialFileDialog:CSpecialFileDialog(BOOL bOpenFileDialog,LPCTSTR lpszDefExt, LPCTSTR lpszFileName, DWORD dwFlags,LPCTSTR lpszFilter, CWnd* pParentWnd): CFileD

12、ialog(bOpenFileDialog, lpszDefExt, lpszFileName,dwFlags, lpszFilter, pParentWnd)/AFX_DATA_INIT(CSpecialFileDialog)/ NOTE: the ClassWizard will add member initialization here/AFX_DATA_INITm_ofn.Flags |= OFN_ENABLETEMPLATE;m_ofn.lpTemplateName = MAKEINTRESOURCE(IDD_FILESPECIAL);m_ofn.lpstrTitle = Dele

13、te File;m_bDeleteAll = FALSE;5、在CSpecialFileDialog類中映射WM_INITDIALOG消息BOOL CSpecialFileDialog:OnInitDialog() BOOL bRet = CFileDialog:OnInitDialog();if (bRet = TRUE) GetParent()-GetDlgItem(IDOK)-SetWindowText(Delete);return bRet;6、在CSpecialFileDialog類中映射IDC_DELETE按鈕void CSpecialFileDialog:OnDelete() m

14、_bDeleteAll = TRUE;/ 0x480 is the child window ID of the File Name edit control/ (as determined by SPYXX)GetParent()-GetDlgItem(0x480)-GetWindowText(m_strFilename);GetParent()-SendMessage(WM_COMMAND, IDCANCEL);void CEx07aView:OnDraw(CDC* pDC)pDC-TextOut(0, 0, Press the left mouse button here.);8、利用C

15、lassWizard加進CEx07aView的鼠標消息處理函數(shù)。加進WM _LBUTTONDOWN消息的處理函數(shù)void CEx07bView:OnLButtonDown(UINT nFlags, CPoint point) CSpecialFileDialog dlgFile(TRUE, NULL, *.obj);CString strMessage;int nModal = dlgFile.DoModal();if (nModal = IDCANCEL) & (dlgFile.m_bDeleteAll) strMessage.Format(Are you sure you want to

16、delete all %s files?,dlgFile.m_strFilename);if (AfxMessageBox(strMessage, MB_YESNO) = IDYES) HANDLE h;WIN32_FIND_DATA fData;while(h = :FindFirstFile(dlgFile.m_strFilename, &fData) != (HANDLE) 0xFFFFFFFF) / no MFC equivalentif (:DeleteFile(fData.cFileName) = FALSE) strMessage.Format(Unable to delete file %sn,fData.cFileName);AfxMessageBox(strMessage);break;else if (nModal = IDOK) CString str
