如何有效地使用对话框

如何有效地使用对话框2010-07-01徐景周Q:如何在对话框中加入工具条在 OnInitDialog 中加入下面代码：

BOOL CYourDlg::OnInitDialog（）
{
    CDialog::OnInitDialog（）;
    // Create the toolbar. To understand the meaning of the styles used, you
    // can take a look at the MSDN for the Create function of the CToolBar class.

    ToolBar.Create（this, WS_CHILD | WS_VISIBLE | CBRS_TOP | CBRS_TOOLTIPS |CBRS_FLYBY | CBRS_BORDER_BOTTOM）;
   // I have assumed that you have named your toolbar""s resource as IDR_TOOLBAR1.
   // If you have given it a different name, change the line below to accomodate
   // that by changing the parameter for the LoadToolBar function.

   ToolBar.LoadToolBar（IDR_TOOLBAR1）;

   CRect rcClientStart;
   CRect rcClientNow;
   GetClientRect（rcClientStart）;
   // To reposition and resize the control bar
   RepositionBars（AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST,0, reposQuery, rcClientNow）;
   CPoint ptOffset（rcClientNow.left - rcClientStart.left,rcClientNow.top-rcClientStart.top）;
   CRect rcChild;
   CWnd* pwndChild = GetWindow（GW_CHILD）;
   while （pwndChild）
   {
    pwndChild->GetWindowRect（rcChild）;
    ScreenToClient（rcChild）;
    rcChild.OffsetRect（ptOffset）;
    pwndChild->MoveWindow（rcChild, FALSE）;
    pwndChild = pwndChild->GetNextWindow（）;
   }
   CRect rcWindow;
   GetWindowRect（rcWindow）;
   rcWindow.right += rcClientStart.Width（） - rcClientNow.Width（）;
   rcWindow.bottom += rcClientStart.Height（） - rcClientNow.Height（）;
   MoveWindow（rcWindow, FALSE）;
   // And position the control bars
   RepositionBars（AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0）;

   return TRUE; // return TRUE unless you set the focus to a control
 }

Q:如何改变对话框的形状？

可用下面一些函数：

CreatePolygonRgn

CreateRectRgn

CreateRoundRectRgn 等.

CRgn m_rgn; // Put this in your dialog""s header file. i.e. a member variable
 // This Gets the size of the Dialog: This piece of code is to be placed in the
 // OnInitDialog Function of your dialog.
 CRect rcDialog
 GetClientRect（rcDialog）;
 // The following code Creates the area and assigns it to your Dialog
 m_rgn.CreateEllipticRgn（0, 0, rcDialog.Width（）, rcDialogHeight（））;
 SetWindowRgn（GetSafeHwnd（）, （HRGN） m_rgn, TRUE）;
