我无法让SendMessage激活另一个程序的菜单。当用户点击菜单查看Spy ++时,会发生以下情况:

然而,当我使用带有WM_NCLBUTTONDOWN的SendMessage尝试相同时,会发生以下情况:
000A0628 P WM_NCLBUTTONDOWN nHittest:HTMENU xPos:1700 yPos:400 [wParam:00000005 lParam:019006A4 time:27:25:02.156 point:(1700, 400)] 000A0628 S WM_SYSCOMMAND uCmdType:SC_MOUSEMENU xPos:1700 yPos:400 [wParam:0000F095 lParam:019006A4] 000A0628 S WM_ENTERMENULOOP fIsTrackPopupMenu:False [wParam:00000000 lParam:00000000] 000A0628 R WM_ENTERMENULOOP lResult:00000000 000A0628 S WM_EXITMENULOOP fIsTrackPopupMenu:False [wParam:00000000 lParam:00000000] 000A0628 R WM_EXITMENULOOP lResult:00000000 000A0628 S WM_MENUSELECT uItem:0 fuFlags:FFFF (menu was closed) hmenu:00000000 [wParam:FFFF0000 lParam:00000000] 000A0628 R WM_MENUSELECT lResult:00000000 000A0628 S WM_EXITMENULOOP fIsTrackPopupMenu:False [wParam:00000000 lParam:00000000] 000A0628 R WM_EXITMENULOOP lResult:00000000 000A0628 R WM_SYSCOMMAND lResult:00000000
有谁知道如何让它正常工作?

您不应使用SendMessage来模拟鼠标点击和按键。请改用SendInput。

我猜测菜单循环测试鼠标按钮的状态。但是,您还没有模拟按下鼠标按钮,您所做的只是发送一条消息,说按钮已关闭。
如果你需要同步行为,我会建议windows hook并让你的线程阻塞到正确的时间。 (换句话说,你可以使用异步方法然后将它包装起来,以便它阻塞并充当同步调用。这是额外的工作,但如果你坚持同步行为来自本质上异步的东西,那么这是你最好的解决方案。)

您可以完美地使用SendMessage(),尤其是菜单(有关代码示例,请参阅MSDN和Google网上论坛组) (和钩子在这里无关)
