我是菜鸟,谁帮帮我!

好不容易知道了屏幕取词的原理,可下一步又不知道怎么做了!
具体如下:
设置鼠标钩子,截取到鼠标停留的字后,怎么在鼠标处画出窗口显示?

有没有人帮忙?

直接往桌面上画，也就是：
CDC *pTopDC=GetDesktopWindow()->GetWindowDC();
CString s("-=======I do it~=======-");
pTopDC->SetBkMode(TRANSPARENT);
pTopDC->SetTextColor(RGB(255,0,0));
pTopDC->TextOut(10, 200, s);
GetDesktopWindow()->ReleaseDC(pTopDC);

在那里Create一个ToolTipWindow吧

[kingzai]

构造一个CMyTip类，基类为CWnd
BOOL CMyTip::Create(CWnd *pParent)
{
m_pParent=pParent;
return CWnd::CreateEx(NULL, AfxRegisterWndClass(0), "tip",
WS_POPUP, 0, 0, 100, 100,
pParent->GetSafeHwnd(), NULL, NULL);

}
void CMyTip::ShowTip(CPoint pt, CString strTip)
{
CClientDC dc(this);
CSize sizeTxt;
CString strTemp;
int nFirst=0;
int nFind;
CFont *pFont = dc.SelectObject(&m_fontText);
ShowWindow(SW_SHOW);
m_strTip=strTip;
m_nHeight=0;
m_nWidth=0;

for(nFind=0; nFind!=-1; )
{
nFind=m_strTip.Find("\n", nFirst);

if (nFind!=-1)
{
strTemp=m_strTip.Mid(nFirst,nFind-nFirst);
sizeTxt=dc.GetTextExtent(strTemp);
}
else
{
strTemp=m_strTip.Mid(nFirst);
sizeTxt=dc.GetTextExtent(strTemp);
}
if(sizeTxt.cx>m_nWidth)
{
m_nWidth=sizeTxt.cx+2;
}
m_nHeight+=sizeTxt.cy;

nFirst=nFind+1;
}

m_nHeight+=2;


//sizeTxt=dc.GetTextExtent(m_strTip);
MoveWindow(pt.x+1,pt.y+1, m_nWidth, m_nHeight);
dc.SelectObject(pFont);
Invalidate();
}
然后CMyTip m_pTip;
int CVfvView::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CView::OnCreate(lpCreateStruct) == -1)
return -1;

// TODO: Add your specialized creation code here
m_pTip.Create(this);
return 0;
}
void CVfvView::OnMouseMove(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default

CView::OnMouseMove(nFlags, point);
//m_pTip.HideTip();
// CRect rcCl;
// GetClientRect(&rcCl);
//rcCl.InflateRect(-2,-2,-2,-2);
// rcCl.top++;
// if(rcCl.PtInRect(point))
{
//ScreenToClient(&point);
ClientToScreen (&point);
CString str;
str.Format("鼠标:\n %d, %d",point.x,point.y);
m_pTip.ShowTip(point,str);
}
}
