MFC中没有标题栏，如何移动窗体

一  移动的时候  没有 虚线的 边框 

void CTransparentDialogDlg::OnLButtonDown(UINT nFlags, CPoint point)

{

// TODO: 在此添加消息处理程序代码和/或调用默认值

SetCapture(); 

CRect rW;

GetWindowRect(rW);

CPoint ptW = point;

ClientToScreen(&ptW);

m_ptCursorOffset.x = ptW.x - rW.left;

m_ptCursorOffset.y = ptW.y - rW.top;

CDialog::OnLButtonDown(nFlags, point);

}

if ((nFlags & MK_LBUTTON) && (this == GetCapture()))

{

CPoint ptW = point;

ClientToScreen(&ptW);

ptW.x -= m_ptCursorOffset.x;

ptW.y -= m_ptCursorOffset.y;

::SetWindowPos(m_hWnd, 0,ptW.x,ptW.y,0,0,SWP_NOSIZE);  // 设置的是 屏幕坐标 

}

void CTransparentDialogDlg::OnLButtonUp(UINT nFlags, CPoint point)

{

// TODO: 在此添加消息处理程序代码和/或调用默认值

ReleaseCapture();

CDialog::OnLButtonUp(nFlags, point);

}

--------------------------------------------

第二种方法    这种方法是发送消息的方式 

void CkaishiDlg::OnLButtonDown(UINT nFlags, CPoint point)

{

SendMessage(WM_NCLBUTTONDOWN,HTCAPTION,MAKELPARAM(point.x,point.y));

    PostMessage(WM_LBUTTONUP,NULL,MAKELPARAM(point.x,point.y));

CDialog::OnLButtonDown(nFlags, point);

}
