用sendmessage怎么发送一个鼠标左键单击事件啊

[kimryo]

不知用WM_LBUTTONDOWN+WM_BUTTONUP行否。

要不用mouse_event算了。

能不能写一下怎么写，里面的参数怎么用啊

[zhaoyao73]

sendmessage(hwnd,BM_CLICK,0,0);

如果不需要鼠标移动到正确位置

[star_chen]

SendMessage(hwnd, WM_LBUTTONDOWN, NULL, NULL);
sleep(30);
SendMessage(hwnd, WM_LBUTTONUP, NULL, NULL);

LPARAM lParam;
LOWORD(lParam) = 50; // horizontal position of cursor
HIWORD(lParam) = 50; // vertical position of cursor
SendMessage(hWnd, WM_LBUTTONDOWN, MK_LBUTTON, lParam);

SendMessage(hWnd, WM_LBUTTONUP, MK_LBUTTON, lParam);
