找到本窗体下面的一个窗体：
GetWindow(hThisWnd, GW_HWNDPREV);
然后用GetWindowRect和GetCursorPos判断数标是否在此窗体内，如果不在，再用上面的函数找下一个窗体直到找到为止

1.先用该函数使下面窗口获得鼠标焦点
HWND SetCapture(
HWND hWnd // handle to window
);
2.在用mouse_event模拟鼠标点击
VOID mouse_event(
DWORD dwFlags, // motion and click options
DWORD dx, // horizontal position or change
DWORD dy, // vertical position or change
DWORD dwData, // wheel movement
ULONG_PTR dwExtraInfo // application-defined information
);
3.还原鼠标焦点到你的顶层窗口
HWND SetCapture(
HWND hWnd // handle to window
);
2.在用mouse_event模拟鼠标点击
VOID mouse_event(
DWORD dwFlags, // motion and click options
DWORD dx, // horizontal position or change
DWORD dy, // vertical position or change
DWORD dwData, // wheel movement
ULONG_PTR dwExtraInfo // application-defined information
);
3.还原鼠标焦点到你的顶层窗口

创建顶层窗口不难，关键是要找到它下面的那个窗口，用FindWindow肯定不行，似乎用Z-Order可以试试，然后SendMessage。

可以创建一个WS_DISABLED属性的窗口，然后调用WindowFormPoint取得鼠标位置窗口句柄，然后调用PostMessage发送鼠标消息。
WS_DISABLED属性是必须的，不然，还要处理键盘焦点。

看我的一段代码：
//m_hWnd是欲置于最顶层的窗口的句柄
CRect RECT_Win;
::GetWindowRect(m_hWnd,&RECT_Win);
::SetWindowPos(m_hWnd,HWND_TOPMOST,RECT_Win.left,RECT_Win.top,
RECT_Win.Width(),RECT_Win.Height(),NULL);
//m_hWnd是欲置于最顶层的窗口的句柄
CRect RECT_Win;
::GetWindowRect(m_hWnd,&RECT_Win);
::SetWindowPos(m_hWnd,HWND_TOPMOST,RECT_Win.left,RECT_Win.top,
RECT_Win.Width(),RECT_Win.Height(),NULL);

CWnd::SetWindowPos
BOOL SetWindowPos( const CWnd* pWndInsertAfter, int x, int y, int cx, int cy, UINT nFlags );
Return Value
Nonzero if the function is successful; otherwise 0.
Parameters
pWndInsertAfter
Identifies the CWnd object that will precede this CWnd object in the Z-order. This parameter can be a pointer to a CWnd or a Pointer to one of the following values:
wndBottom Places the window at the bottom of the Z-order. If this CWnd is a topmost window, the window loses its topmost status; the system places the window at the bottom of all other windows.
wndTop Places the window at the top of the Z-order.
wndTopMost Places the window above all nontopmost windows. The window maintains its topmost position even when it is deactivated.
wndNoTopMost Repositions the window to the top of all nontopmost windows (that is, behind all topmost windows). This flag has no effect if the window is already a nontopmost window.
See the “Remarks” section for this function for rules about how this parameter is used.
x
Specifies the new position of the left side of the window.
y
Specifies the new position of the top of the window.
cx
Specifies the new width of the window.
cy
Specifies the new height of the window.
nFlags
Specifies sizing and positioning options. This parameter can be a combination of the following:
SWP_DRAWFRAME Draws a frame (defined when the window was created) around the window.
SWP_FRAMECHANGED Sends a WM_NCCALCSIZE message to the window, even if the window's size is not being changed. If this flag is not specified, WM_NCCALCSIZE is sent only when the window's size is being changed.
SWP_HIDEWINDOW Hides the window.
SWP_NOACTIVATE Does not activate the window. If this flag is not set, the window is activated and moved to the top of either the topmost or the nontopmost group (depending on the setting of the pWndInsertAfter parameter).
SWP_NOCOPYBITS Discards the entire contents of the client area. If this flag is not specified, the valid contents of the client area are saved and copied back into the client area after the window is sized or repositioned.
SWP_NOMOVE Retains current position (ignores the x and y parameters).
SWP_NOOWNERZORDER Does not change the owner window’s position in the Z-order.
SWP_NOREDRAW Does not redraw changes. If this flag is set, no repainting of any kind occurs. This applies to the client area, the nonclient area (including the title and scroll bars), and any part of the parent window uncovered as a result of the moved window. When this flag is set, the application must explicitly invalidate or redraw any parts of the window and parent window that must be redrawn.
SWP_NOREPOSITION Same as SWP_NOOWNERZORDER.
SWP_NOSENDCHANGING Prevents the window from receiving the WM_WINDOWPOSCHANGING message.
SWP_NOSIZE Retains current size (ignores the cx and cy parameters).
SWP_NOZORDER Retains current ordering (ignores pWndInsertAfter).
SWP_SHOWWINDOW Displays the window.
Remarks
Call this member function to change the size, position, and Z-order of child, pop-up, and top-level windows.
Windows are ordered on the screen according to their Z-order; the window at the top of the Z-order appears on top of all other windows in the order.
All coordinates for child windows are client coordinates (relative to the upper-left corner of the parent window’s client area).
A window can be moved to the top of the Z-order either by setting the pWndInsertAfter parameter to &wndTopMost and ensuring that the SWP_NOZORDER flag is not set or by setting a window’s Z-order so that it is above any existing topmost windows. When a nontopmost window is made topmost, its owned windows are also made topmost. Its owners are not changed.
A topmost window is no longer topmost if it is repositioned to the bottom (&wndBottom) of the Z-order or after any nontopmost window. When a topmost window is made nontopmost, all of its owners and its owned windows are also made nontopmost windows.
If neither SWP_NOACTIVATE nor SWP_NOZORDER is specified (that is, when the application requests that a window be simultaneously activated and placed in the specified Z-order), the value specified in pWndInsertAfter is used only in the following circumstances:
Neither &wndTopMost nor &wndNoTopMost is specified in the pWndInsertAfter parameter.
This window is not the active window.
An application cannot activate an inactive window without also bringing it to the top of the Z-order. Applications can change the Z-order of an activated window without restrictions.
A nontopmost window may own a topmost window, but not vice versa. Any window (for example, a dialog box) owned by a topmost window is itself made a topmost window to ensure that all owned windows stay above their owner.
With Windows versions 3.1 and later, windows can be moved to the top of the Z-order and locked there by setting their WS_EX_TOPMOST styles. Such a topmost window maintains its topmost position even when deactivated. For example, selecting the WinHelp Always On Top command makes the Help window topmost, and it then remains visible when you return to your application.
To create a topmost window, call SetWindowPos with the pWndInsertAfter parameter equal to &wndTopMost, or set the WS_EX_TOPMOST style when you create the window.
If the Z-order contains any windows with the WS_EX_TOPMOST style, a window moved with the &wndTopMost value is placed at the top of all nontopmost windows, but below any topmost windows. When an application activates an inactive window without the WS_EX_TOPMOST bit, the window is moved above all nontopmost windows but below any topmost windows.
If SetWindowPos is called when the pWndInsertAfter parameter is &wndBottom and CWnd is a topmost window, the window loses its topmost status (WS_EX_TOPMOST is cleared), and the system places the window at the bottom of the Z-order.
BOOL SetWindowPos( const CWnd* pWndInsertAfter, int x, int y, int cx, int cy, UINT nFlags );
Return Value
Nonzero if the function is successful; otherwise 0.
Parameters
pWndInsertAfter
Identifies the CWnd object that will precede this CWnd object in the Z-order. This parameter can be a pointer to a CWnd or a Pointer to one of the following values:
wndBottom Places the window at the bottom of the Z-order. If this CWnd is a topmost window, the window loses its topmost status; the system places the window at the bottom of all other windows.
wndTop Places the window at the top of the Z-order.
wndTopMost Places the window above all nontopmost windows. The window maintains its topmost position even when it is deactivated.
wndNoTopMost Repositions the window to the top of all nontopmost windows (that is, behind all topmost windows). This flag has no effect if the window is already a nontopmost window.
See the “Remarks” section for this function for rules about how this parameter is used.
x
Specifies the new position of the left side of the window.
y
Specifies the new position of the top of the window.
cx
Specifies the new width of the window.

SWP_DRAWFRAME Draws a frame (defined when the window was created) around the window.
SWP_FRAMECHANGED Sends a WM_NCCALCSIZE message to the window, even if the window's size is not being changed. If this flag is not specified, WM_NCCALCSIZE is sent only when the window's size is being changed.

关键问题是你怎么知道它下面是哪一个窗口呀！
lwglucky 2002-07-28
真难。。
bljbljbljblj 2002-07-28
1。顶层显示就不用说了吧
2。列出Z-ORDER中的所有窗体
3。在Z—ORDER方向上从上往下依次判断点是否在窗体内，如果是，向该窗体发送消息

1 用setwindowpos函数设为顶层
2 在该顶层窗口捕捉消息，用API函数 SendMessage把该消息发给你下面的 窗口去处理

很简单！
首先用setwindowpos函数设为顶层或者在创建窗口时设定
然后在该顶层窗口捕捉消息，用API函数 SendMessage把该消息发给你下面的窗口去处理！oK?
