高人帮忙看看下面代码,仅仅是一个对话框上加一个按钮,然后用WM_SIZE来响应对话框大小变化,然后在OnSize()中改变按钮的大小。但是运行不了,为什么?// xxTabRectDlg.cpp : implementation file //#include "stdafx.h" #include "xxTabRect.h" #include "xxTabRectDlg.h"#ifdef _DEBUG #define new DEBUG_NEW #undef THIS_FILE static char THIS_FILE[] = __FILE__; #endif///////////////////////////////////////////////////////////////////////////// // CAboutDlg dialog used for App Aboutclass CAboutDlg : public CDialog { public: CAboutDlg();// Dialog Data //{{AFX_DATA(CAboutDlg) enum { IDD = IDD_ABOUTBOX }; //}}AFX_DATA // ClassWizard generated virtual function overrides //{{AFX_VIRTUAL(CAboutDlg) protected: virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support //}}AFX_VIRTUAL// Implementation protected: //{{AFX_MSG(CAboutDlg) //}}AFX_MSG DECLARE_MESSAGE_MAP() };CAboutDlg::CAboutDlg() : CDialog(CAboutDlg::IDD) { //{{AFX_DATA_INIT(CAboutDlg) //}}AFX_DATA_INIT }void CAboutDlg::DoDataExchange(CDataExchange* pDX) { CDialog::DoDataExchange(pDX); //{{AFX_DATA_MAP(CAboutDlg) //}}AFX_DATA_MAP }BEGIN_MESSAGE_MAP(CAboutDlg, CDialog) //{{AFX_MSG_MAP(CAboutDlg) // No message handlers //}}AFX_MSG_MAP END_MESSAGE_MAP()///////////////////////////////////////////////////////////////////////////// // CXxTabRectDlg dialogCXxTabRectDlg::CXxTabRectDlg(CWnd* pParent /*=NULL*/) : CDialog(CXxTabRectDlg::IDD, pParent) { //{{AFX_DATA_INIT(CXxTabRectDlg) // NOTE: the ClassWizard will add member initialization here //}}AFX_DATA_INIT // Note that LoadIcon does not require a subsequent DestroyIcon in Win32 m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME); }void CXxTabRectDlg::DoDataExchange(CDataExchange* pDX) { CDialog::DoDataExchange(pDX); //{{AFX_DATA_MAP(CXxTabRectDlg) // NOTE: the ClassWizard will add DDX and DDV calls here //}}AFX_DATA_MAP }BEGIN_MESSAGE_MAP(CXxTabRectDlg, CDialog) //{{AFX_MSG_MAP(CXxTabRectDlg) ON_WM_SYSCOMMAND() ON_WM_PAINT() ON_WM_QUERYDRAGICON() ON_WM_SIZE() //}}AFX_MSG_MAP END_MESSAGE_MAP()///////////////////////////////////////////////////////////////////////////// // CXxTabRectDlg message handlersBOOL CXxTabRectDlg::OnInitDialog() { CDialog::OnInitDialog(); // Add "About..." menu item to system menu. // IDM_ABOUTBOX must be in the system command range.

在窗口的WM_SIZE中控制,当改变窗口大小时,会随着改变。

另外,OnInitDialog中的代码应该是不需要的。OnSize中MoveWindow的参数怎么与OnInitDialog中的不同?
然后在CTabDlg1上放置一个static组框。
现在希望当主对话框CTestDlg大小变化时,CTabCtrl控件随之改变大小,而CTabDlg1和CTabDlg2也随之改变,并且static组框也随之改变。这样的案例该怎么弄了,我试的总达不到目的.......
关键在于第一次还没有resize时会出错
所以要先判断一下是不是空句柄void CCstest11Dlg::OnSize(UINT nType, int cx, int cy)
{
CDialog::OnSize(nType, cx, cy);
// TODO: Add your message handler code here
CRect rect(0,0,cx,cy);
