7 ClassWizard 了什 ActiveX ClassWizard 列 BEGIN_DISPATCH_MAP(CClockCtrl, COleControl) //AFX_DISPATCH_MAP(CClockCtrl) DISP_STOCKPROP_FORECOLOR() //AFX_DISPATCH_MAP DISP_FUNCTION_ID(CClockCtrl, "AboutBox", DISPID_ABOUTBOX, AboutBox, VT_EMPTY, VTS_NONE) END_DISPATCH_MAP() COleControl::InvalidateControl() 更 InvalidateControl 理 數 例 例 更 InvalidateControl OnForeColorChanged() void CClockCtrl::OnForeColorChanged() // TODO: Add your specialized code here and/or call the base class MessageBox("ForeColor is Changed") ; COleControl::OnForeColorChanged(); 了 VC 了 列 不 行 Dispatch map entry macro 料 DISP_PROPERTY_NOTIFY 更 理 數 料 (Member Variable) DISP_PROPERTY 都 Get/Set Method DISP_PROPERTY_EX 行 參數 DISP_PROPERTY_PARAM 來 Get Set 了 ActiveX 都 更 - 7 -

8 不 行 Dispatch map entry macro 參數 1. ClassWizard 2. Automation class name Add Property 3. External name 4. Type 欄 5. Implementation Member Variable Get/Set Method 6. OK ClassWizard OK Get/Set Method 來 Get/Set 來 Get : Set : 更 不 Add Property - 8 -

9 Add Property ClassWizard Edit Code 例 BOOL CClockCtrl::GetIsChecked() // TODO: Add your property handler here if (m_bpaied == TRUE) return TRUE; else return FALSE; void CClockCtrl::SetIsChecked(BOOL bnewvalue) // TODO: Add your property handler here m_bpaied = bnewvalue ; SetModifiedFlag(); 立 立 Read-Only Write-Only Get Set 數 Read-Only Set 數 Write-Only Get 數 - 9 -

10 立參數 參數 立 Get/Set Method 立 Add Property Parameter List 參數 15 CURRENCY CClockCtrl::GetSetPrice(long nquantity, short ncuslevel) CURRENCY cyresult=0,0; // TODO: Add your property handler here return cyresult; void CClockCtrl::SetSetPrice(long nquantity, short ncuslevel, CURRENCY newvalue) // TODO: Add your property handler here SetModifiedFlag();

11 例 MFC 了 數 COleControl::GetAmbientProperty() 數 Dispatch ID Dispatch ID OleCtl.h 行 COleControl function AmbientBackColor AmbientDiaplayName AmbientFont AmbientForeColor AmbientLocaleID AmbientTextAlign AmbientUserMode AmbientUIDead ID 識 兩 行 Dispatch ID OleCtl.h 裡列 OleCtl.h #define DISPID_AUTOSIZE (-500) #define DISPID_BACKCOLOR (-501) #define DISPID_BACKSTYLE (-502) #define DISPID_BORDERCOLOR (-503) #define DISPID_BORDERSTYLE (-504) #define DISPID_BORDERWIDTH (-505) #define DISPID_DRAWMODE (-507) #define DISPID_DRAWSTYLE (-508) #define DISPID_DRAWWIDTH (-509) #define DISPID_FILLCOLOR (-510) #define DISPID_FILLSTYLE (-511) #define DISPID_FONT (-512) #define DISPID_FORECOLOR (-513) #define DISPID_ENABLED (-514) #define DISPID_HWND (-515) #define DISPID_TABSTOP (-516) #define DISPID_TEXT (-517) #define DISPID_CAPTION (-518) #define DISPID_BORDERVISIBLE (-519) #define DISPID_APPEARANCE (-520)

15 (Property Page) 來 立 1. Dialog DIALOG 2. DIALOG 來 ActiveX 3. ClassWizard 立 Dialog Class 料 料 4. Member Variable Control ID 數 [Add Variable]

16 類 DoDataExchange 數 數 DDX(Do Data Exchange) 來 類 料 行 料 說 OK DoDataExchange() 更 類 料 例 void CDialog2::DoDataExchange(CDataExchange* pdx) CDialog::DoDataExchange(pDX); //AFX_DATA_MAP(CDialog2) DDX_Text(pDX, IDC_EDIT1, m_test1); //AFX_DATA_MAP DDX 不 參 MFC Property Dialog 料 DoDataExchange() 來 料 料 DDP 數來 料 DDP_Text(pDX, IDC_CAPTION, Caption ) pdx 料 IDC CAPTION ID Catpion ActiveX Caption DDP 數 列 DDP_CBIndex 連 combo box 串索 DDP_CBString 連 combo box 串 DDP_CBStringExact combo box DDP_Check Check Box DDP_LBIndex 連 list box 串索 DDP_LBString 連 list box 串 DDP_LBStringExact list box DDP_Radio Radio Button DDP_Text

17 DDP 例 //AFX_DATA_MAP(CAlarmPropPage) DDP_Text(pDX, IDC_ALARM_HOUR, m_alarmhour, _T("AlarmHour") ); DDX_Text(pDX, IDC_ALARM_HOUR, m_alarmhour); DDV_MinMaxInt(pDX, m_alarmhour, 0, 23); DDP_Text(pDX, IDC_ALARM_MINUTE, m_alarmminute, _T("AlarmMinute") ); DDX_Text(pDX, IDC_ALARM_MINUTE, m_alarmminute); DDV_MinMaxInt(pDX, m_alarmminute, 0, 59); DDP_Text(pDX, IDC_ALARM_SOUND, m_alarmsound, _T("AlarmSound") ); DDX_Text(pDX, IDC_ALARM_SOUND, m_alarmsound); DDP_Text(pDX, IDC_ALARM_COMMAND, m_alarmcommand, _T("AlarmCommand") ); DDX_Text(pDX, IDC_ALARM_COMMAND, m_alarmcommand); DDP_Check(pDX, IDC_ALARM_SET, m_balarmset, _T("AlarmSet") ); DDX_Check(pDX, IDC_ALARM_SET, m_balarmset); DDP_CBIndex(pDX, IDC_ALARM_TYPE, m_alarmtype, _T("AlarmType") ); DDX_CBIndex(pDX, IDC_ALARM_TYPE, m_alarmtype); //AFX_DATA_MAP DDP_PostProcessing(pDX); MFC 了 Class ID Font chooser CLSID_CFontPropPage Pricture chooser CLSID_CPicturePropPage Color chooser CLSID_CColorPropPage CXxxCtrl BEGIN_PROPPAGEIDS(CClockCtrl, 3) PROPPAGEID(CClockPropPage::guid) PROPPAGEID(CAlarmPropPage::guid) PROPPAGEID(CLSID_CColorPropPage) END_PROPPAGEIDS(CClockCtrl) 了

18 1. 量不 2. 量不 連 3. 立 1. 立 Property Page 2. Property Page 3. 立 Property Class 4. Property Page 立 立 1. 立 2. IDD_PROPPAGE_Xxxx(Xxxx ) 3. child window thin border 4. TitleBar Visible 都 x x 110 compiler 不 立 類 i.. ClassWizard ii. 立 類 類 類 COlePropertyPage iii. OK 1. String Table ID 例 IDS_Xxxx_PPG 串 Xxxx Property Page 2. 串 例 IDS_Xxxx_PPG_CAPTION 串 Xxxx 3. UpdateRegistry() 數 更 AfxOleRegisterPropertyPage 數 BOOL CXxxx::CXxxxFactory::UpdateRegistry(BOOL bregister) // TODO: Define string resource for page type; replace '0' below with ID. if (bregister) return AfxOleRegisterPropertyPageClass(AfxGetInstanceHandle(),m_clsid, IDS_Xxxx_PPG ); else return AfxOleUnregisterClass(m_clsid, NULL);

19 4. 來 類 串列 COlePropertyPage() 參數 ID CXxxx::CXxxx() : COlePropertyPage(IDD, IDD_Xxxx_PPG_CAPTION) //AFX_DATA_INIT(CXxxx) // NOTE: ClassWizard will add member initialization here // DO NOT EDIT what you see in these blocks of generated code! //AFX_DATA_INIT 5. map

20 1. 立 ROC 2. 來精靈 都 行 3. Class ClassWizard ROC 數 m_broc BOOL 4. OK CLASSWIZARD EDIT CODE OnRocChanged() InvalidateControl() void CROCCtrl::OnROCChanged() // TODO: Add notification handler code InvalidateControl(); SetModifiedFlag(); 5. 來 CROCCtrl 兩 料 CString m_strroc ; CString m_strstd; 來 錄 年 年

21 6. CROCCtrl::OnDraw // TODO: Replace the following code with your own drawing code. CBrush brush(rgb(128,128,0)) ; pdc->fillrect(rcbounds, &brush) ; int x = rcbounds.right / 3 ; int y = rcbounds.bottom / 4 ; if ( m_broc) pdc->textout(x, y, m_strroc) ; else pdc->textout(x, y, m_strstd) ; 7. CROCCtrl 利 ClassWizard 兩 MESSAGE HANDLER WM CREATE 理 OnCreate() WM_DESTROY 理 數 OnDestroy(); 8. OnCreate() int CROCCtrl::OnCreate(LPCREATESTRUCT lpcreatestruct) if (COleControl::OnCreate(lpCreateStruct) == -1) return -1; SetTimer(1, 1000, NULL) ; return 0; 9. OnDestroy() void CROCCtrl::OnDestroy() COleControl::OnDestroy(); KillTimer(1) ; 10. ` TIMER 來 ClassWizard WM_TIMER 來 TIMER void CROCCtrl::OnTimer(UINT nidevent) // TODO: Add your message handler code here and/or call default COleDateTime today = COleDateTime::GetCurrentTime() ; char year[5] ; char output[50] ; strcpy(output, " " ) ; itoa(today.getyear() , year, 10 ) ; strcat(output, year ) ; strcat(output, " 年 " ) ; m_strroc = output ; strcpy(output, " 年 " ) ; itoa(today.getyear(), year, 10 ) ; strcat(output, year ) ; strcat(output, " 年 " ) ;

22 m_strstd = output ; COleControl::OnTimer(nIDEvent); 11. 來 Property Page 12. Resource Editor 立 OlePropertyPage 13. IDD_PROPPAGE_SET String Table 立 IDS_SET_PPG [ ] IDS_SET_PPG_CAPTION [ ] 14. 利 ClassWizard 立 CLASS CSetPropPage 類 COlePropertyPage. UpdateRegistry() 更 ID 類 參數 CROCCtrl Property Page Map 15. 來 ClassWizard 拉 IDC_CHECK1 料 m_broc; BOOL 16. DDP CSetPropPage::OnDataExchange() 行 void CSetPropPage::DoDataExchange(CDataExchange* pdx) // NOTE: ClassWizard will add DDP, DDX, and DDV calls here // DO NOT EDIT what you see in these blocks of generated code! //AFX_DATA_MAP(CSetPropPage) DDX_Check(pDX, IDC_CHECK1, m_broc); DDP_Check(pDX, IDC_CHECK1, m_broc, "ROC") ; //AFX_DATA_MAP DDP_PostProcessing(pDX);
