拦截鼠标消息？

谢谢，现在就是这样做的。 OpenCV对双击左键的响应居然是先响应一次单击，然后再响应双击。不晓得有没有办法进一步过滤！

WM_LBUTTONDBLCLK The WM_LBUTTONDBLCLK message is posted when the user double-clicks the left mouse button while the cursor is in the client area of a window. If the mouse is not captured, the message is posted to the window beneath the cursor. Otherwise, the message is posted to the window that has captured the mouse. WM_LBUTTONDBLCLK fwKeys = wParam; // key flags xPos = LOWORD(lParam); // horizontal position of cursor yPos = HIWORD(lParam); // vertical position of cursor Parameters fwKeys Value of wParam. Indicates whether various virtual keys are down. This parameter can be any combination of the following values: Value Description MK_CONTROL Set if the ctrl key is down. MK_LBUTTON Set if the left mouse button is down. MK_MBUTTON Set if the middle mouse button is down. MK_RBUTTON Set if the right mouse button is down. MK_SHIFT Set if the shift key is down. xPos Value of the low-order word of lParam. Specifies the x-coordinate of the cursor. The coordinate is relative to the upper-left corner of the client area. yPos Value of the high-order word of lParam. Specifies the y-coordinate of the cursor. The coordinate is relative to the upper-left corner of the client area. Return Values If an application processes this message, it should return zero. Remarks Only windows that have the CS_DBLCLKS style can receive WM_LBUTTONDBLCLK messages, which the system generates whenever the user presses, releases, and again presses the left mouse button within the system's double-click time limit. Double-clicking the left mouse button actually generates four messages: WM_LBUTTONDOWN, WM_LBUTTONUP, WM_LBUTTONDBLCLK, and WM_LBUTTONUP again. An application can use the MAKEPOINTS macro to convert the lParam parameter to a POINTS structure. QuickInfo Windows NT: Requires version 3.1 or later. Windows: Requires Windows 95 or later.
