Windows編程之非模態對話框

//  注：  最近真不是喜歡上windows編程了..  項目需要啊

  設置程序圖標：

////應用程序圖標
static HICON hIcon1 = LoadIcon(hApp, MAKEINTRESOURCE(IDI_ICON1));
SendMessage(hMainWnd, WM_SETICON, ICON_BIG, (LPARAM)hIcon1);    //任務欄 alt + tab
SendMessage(hMainWnd, WM_SETICON, ICON_SMALL, (LPARAM)hIcon1);  //標題欄 程序exe圖標

1  創建非模態對話框

<1>  HWNDCreateDialog(  HINSTANCE hInstance,  // handle to module

                LPCTSTRlpTemplate,    // dialog box template name

                HWNDhWndParent,    // handle to owner window

                DLGPROClpDialogFunc  // dialog box procedure);

<2> HWND CreateDialogIndirect(  HINSTANCE hInstance,        // handle to module

                LPCDLGTEMPLATE lpTemplate,   //dialog box template

                HWND hWndParent,           // handle to owner window

                DLGPROC lpDialogFunc         //dialog box procedure);

<3> HWND CreateDialogIndirectParam(  HINSTANCE hInstance,   // handle to module

                LPCDLGTEMPLATE lpTemplate,  // dialog box template

                HWND hWndParent,          // handle to owner window

                DLGPROC lpDialogFunc,       // dialog box procedure

                LPARAM lParamInit           // initialization value);

<4> HWND CreateDialogParam(  HINSTANCE hInstance,     // handle to module

                LPCTSTR lpTemplateName,    //dialog box template

                HWND hWndParent,         // handle to owner window

                DLGPROC lpDialogFunc,      //dialog box procedure

                LPARAM dwInitParam        //initialization value);

         參數跟非模態對話框一致。CreateDialogParam會調用CreateWindowExe去創建一個窗口，所以這樣的對話框其實就是窗口。當然單獨一個對話框可以沒有父窗口直接單獨存在。

2   含有父窗口的對話框程序

3 自定義窗口類（無父窗口）的對話框程序

<1>在腳本中指定對話框的類型以及各種控件假定腳本名稱爲new.dlg

<2>然後在rc文件中添加腳本

<3>在WinMain函數註冊窗口類

         注意這裏的CreateDialog的最後一個參數DLGPROC爲NULL，因爲在窗口類中指定了窗口過程函數。

int WINAPI WinMain (HINSTANCE hInstance, HINSTANCEhPrevInstance,PSTR szCmdLine, intiCmdShow)
{
    staticTCHAR szAppName[] = TEXT ("HexCalc");
    HWND                    hwnd ;
    MSG                     msg ;
    WNDCLASS                wndclass ;

    wndclass.style              = CS_HREDRAW | CS_VREDRAW ;
    wndclass.lpfnWndProc        = WndProc ;
    wndclass.cbClsExtra         = 0 ;
    wndclass.cbWndExtra         = DLGWINDOWEXTRA ; // note here
    wndclass.hInstance          = hInstance ;
    wndclass.hIcon              = LoadIcon (NULL, IDI_APPLICATION) ;
    wndclass.hCursor            = LoadCursor (NULL, IDC_ARROW) ;
    wndclass.hbrBackground      = (HBRUSH) GetStockObject (WHITE_BRUSH) ;
    wndclass.lpszMenuName       = NULL ;
    wndclass.lpszClassName      =szAppName ;

    if(!RegisterClass (&wndclass))
         {
        MessageBox (  NULL, TEXT ("Thisprogram requires Windows NT!"), szAppName, MB_ICONERROR) ;
        return0 ;
    }

         hwnd =CreateDialog(hInstance,szAppName,NULL,NULL);    //note here

    ShowWindow (hwnd, iCmdShow) ;
    UpdateWindow (hwnd) ;

    while(GetMessage (&msg, NULL, 0, 0))
         {
                   TranslateMessage (&msg) ;
                   DispatchMessage (&msg) ;
    }

    returnmsg.wParam ;
}

生成的窗口程序程序如圖所示：

12 從資源加載（無父窗口）的對話框程序

LRESULT CALLBACKWndProc(HWND,UINT,WPARAM,LPARAM) ;
int WINAPI WinMain (HINSTANCE hInstance, HINSTANCEhPrevInstance,PSTR szCmdLine, intiCmdShow)
{
    HWND                    hwnd ;
    MSG                     msg ;

         //hwnd =CreateDialog(hInstance,MAKEINTRESOURCE(IDD_DIALOG1),NULL,(DLGPROC)WndProc);
    hwnd =CreateDialogParam(hInstance,MAKEINTRESOURCE(IDD_DIALOG1),NULL,(DLGPROC)WndProc,NULL);

    ShowWindow (hwnd, iCmdShow) ;
    UpdateWindow (hwnd) ;

    while(GetMessage (&msg, NULL, 0, 0))
         {
                   TranslateMessage (&msg) ;
                   DispatchMessage (&msg) ;
    }
    returnmsg.wParam ;
}

可以看到這裏沒有窗口的設計，窗口的註冊，因爲這種從資源加載的對話框的窗口類是已經定義的，就像那種PushButton一樣，都是定義好的窗口的類，因而不需要註冊。

生成的單獨對話框程序如下圖所示：
