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);
