html给父窗口发消息,子窗口向父窗口发送消息

1.自定义对话框中，

m_pView 是父窗口的指针

void CEx07cDialog::OnBnClickedOk()

{

if (m_pView != NULL) {

// modeless case -- do not call base class OnOK

UpdateData(TRUE);

m_pView->PostMessage(WM_GOODBYE, IDOK);

}

else {

CDialog::OnOK(); // modal case

}

}

2.父窗口响应

BEGIN_MESSAGE_MAP(CEx07cView, CView)

ON_WM_LBUTTONDOWN()

ON_WM_RBUTTONDOWN()

ON_MESSAGE(WM_GOODBYE, OnGoodbye) //通过这个宏

END_MESSAGE_MAP()

LRESULT CEx07cView::OnGoodbye(WPARAM wParam, LPARAM lParam){    // message received in response to modeless dialog OK    //  and Cancel buttons    TRACE("CEx07cView::OnGoodbye %x, %lx/n", wParam, lParam);    TRACE("Dialog edit1 contents = %s/n",           (const char*) m_pDlg->m_strEdit1);    m_pDlg->DestroyWindow();    return 0L;}
