我使用 keybd_event 函数来模拟 SHIFT+END 组合键，但它不起作用：

keybd_event(VK_SHIFT,0,0,0);
keybd_event(VK_END,0,0,0);
keybd_event(VK_END,0,KEYEVENTF_KEYUP,0);
keybd_event(VK_SHIFT,0,KEYEVENTF_KEYUP,0);

插入符号移动到行尾，但不要选择文本（突出显示）。就像输入一个 END 键一样。有人可以帮忙吗？非常感谢~

我已经解决了这个问题！我使用 spy++ 来查找当我使用键盘发送键 Shift + End 时会发生什么，我收到了以下消息：

WM_KEYDOWN nVirtKey:VK_SHIFT cRepeat:1 ScanCode:2A fExtended:0 fAltDown:0 fRepeat:0 fUp:0
WM_KEYDOWN nVirtKey:VK_END cRepeat:1 ScanCode:4F fExtended:1 fAltDown:0 fRepeat:0 fUp:0
WM_KEYUP nVirtKey:VK_END cRepeat:1 ScanCode:4F fExtended:1 fAltDown:0 fRepeat:1 fUp:1
WM_KEYUP nVirtKey:VK_SHIFT cRepeat:1 ScanCode:2A fExtended:0 fAltDown:0 fRepeat:1 fUp:1

当我运行上面的代码时，我收到了这些消息：

WM_KEYDOWN nVirtKey:VK_SHIFT cRepeat:1 ScanCode:0 fExtended:0 fAltDown:0 fRepeat:0 fUp:0
WM_KEYUP nVirtKey:VK_SHIFT cRepeat:1 ScanCode:0 fExtended:0 fAltDown:0 fRepeat:1 fUp:1
WM_KEYDOWN nVirtKey:VK_END cRepeat:1 ScanCode:0 fExtended:1 fAltDown:0 fRepeat:0 fUp:0
WM_KEYUP nVirtKey:VK_END cRepeat:1 ScanCode:0 fExtended:1 fAltDown:0 fRepeat:1 fUp:1
WM_KEYDOWN nVirtKey:VK_SHIFT cRepeat:1 ScanCode:0 fExtended:0 fAltDown:0 fRepeat:0 fUp:0
WM_KEYUP nVirtKey:VK_SHIFT cRepeat:1 ScanCode:0 fExtended:0 fAltDown:0 fRepeat:1 fUp:1

窗口在 VK_END 的 WM_KEYDOWN 消息之前获得 VK_SHIFT 的 WM_KEYUP 消息。消息之间的区别在于“fExtended”的值。当我使用键盘时，END键的fExtended值为1，而当我运行代码时值为0。所以我尝试将fExtended值设置为1，我发现keybd_event函数的“dwFlags [in]”参数. 当我按如下方式运行代码时，组合键有效：

keybd_event(VK_SHIFT,0x2A,0,0);
keybd_event(VK_END,0x4F,KEYEVENTF_EXTENDEDKEY | 0,0);
keybd_event(VK_END,0x4F,KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP,0);
keybd_event(VK_SHIFT,0x2A,KEYEVENTF_KEYUP,0);

UINT m_scanShift = MapVirtualKey(VK_SHIFT, 0);
UINT m_scanEnd   = MapVirtualKey(VK_END, 0);

keybd_event(VK_SHIFT, m_scanShift, 0, 0);
Sleep(10);
keybd_event(VK_END, m_scanEnd, 0, 0);
Sleep(10);
keybd_event(VK_END, m_scanEnd, KEYEVENTF_KEYUP, 0);
Sleep(10);
keybd_event(VK_SHIFT, m_scanShift, KEYEVENTF_KEYUP, 0);

使用 shift VK_LSHIFT 和 VK_RSHIFT down 然后 VK_END 然后同时向左和向右 SHIFT UP 对我有用
