怎么在窗口的任意区域不受任何条件约束地显示一个提示(ToolTip)

[boybaby]

包括用不着联系一个控件就能显示。答出来者给500分，不够再加。

我发现CSDN问题越来越多了，提前也无法成功，速度也越来越慢了，是不是CSDN服务器坏了！！！

BOOL CXXXView::PreTranslateMessage(MSG* pMsg)
{
// TODO: Add your specialized code here and/or call the base class
if(m_ctrlHotTip.m_hWnd != 0)
m_ctrlHotTip.RelayEvent(pMsg);
return CView::PreTranslateMessage(pMsg);
}

void CXXXView::OnMouseMove(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
if(m_rect.PtInRect(point))
{
m_ctrlHotTip.AddTool(this,LPCTSTR("在此rect中));
m_ctrlHotTip.Activate(TRUE);
}
CView::OnMouseMove(nFlags, point);
}

you can use tooltip wnd,example:
BOOL CPopupTipWnd::Create(CWnd *pParentWnd)
{
_ASSERTE(pParentWnd);

m_pParentWnd = pParentWnd;

DWORD dwStyle = WS_BORDER | WS_POPUP;
DWORD dwExStyle = WS_EX_TOOLWINDOW | WS_EX_TOPMOST;

BOOL bCreated = CreateEx(dwExStyle,
PWDSPY_POPUP_TIP_CLASSNAME,
NULL,
dwStyle,
0, 0, 0, 0,
NULL, NULL, NULL);

return bCreated;
}

//***********************************************
bool CPopupTipWnd::RegisterWindowClass(void)
{
WNDCLASS wndcls = {0};
wndcls.style = CS_SAVEBITS | CS_DBLCLKS | CS_HREDRAW | CS_VREDRAW;
wndcls.lpfnWndProc = ::DefWindowProc;
wndcls.hCursor = (HCURSOR)::LoadImage(NULL, IDC_ARROW, IMAGE_CURSOR, 0, 0, LR_DEFAULTSIZE);
wndcls.hbrBackground = (HBRUSH)(COLOR_INFOBK + 1);
wndcls.lpszClassName = PWDSPY_POPUP_TIP_CLASSNAME;

if(!::RegisterClass(&wndcls))
{
AfxThrowResourceException();
return false;
}

return true;
}

//***********************************************
void CPopupTipWnd::ShowPopupWindow(CString strText, CPoint point, CRect rect)
{
// If there is no password, instead hide the window and be done with it
if(strText.IsEmpty())
{
HidePopupWindow();
return;
}

CClientDC dc(this);

// Use same font as parent window
CFont *pOldFont = dc.SelectObject(m_pParentWnd->GetFont());

// Calculate the window size.
CSize sizeText = dc.GetTextExtent(strText);
CSize sizeWindow;
sizeWindow.cx = sizeText.cx + 2 * BORDER_X;
sizeWindow.cy = sizeText.cy + 2 * BORDER_Y;

// Draw information in window
dc.SetBkMode(TRANSPARENT);
dc.DrawText(strText, CRect(0, 0, sizeWindow.cx, sizeWindow.cy), DT_CENTER | DT_VCENTER | DT_SINGLELINE);
dc.SelectObject(pOldFont);

// Calculate window rectangle position on screen
CRect rectWindow;
rectWindow.left = rect.left;
rectWindow.right = rectWindow.left + sizeWindow.cx;
rectWindow.top = rect.top - (sizeWindow.cy + 20);
if(rectWindow.top <= 0)
rectWindow.top = rect.bottom + 20;
rectWindow.bottom = rectWindow.top + sizeWindow.cy;

// Display window
SetWindowPos(&wndTop,
rectWindow.left,
rectWindow.top,
rectWindow.Width(),
rectWindow.Height(),
SWP_SHOWWINDOW | SWP_NOACTIVATE);
}

//***********************************************
void CPopupTipWnd::HidePopupWindow(void)
{
ShowWindow(SW_HIDE);
}

不知道一个CToolTipCtrl不和一个普通控件连系在一起是否能够显示消息提示
