我正在使用低级挂钩,但我无法确定按下了哪个键。每个键的值都相同。这是我做错了吗?
钩子方法
void hook() {
/** this part is probably not important since I use global WH_KEYBOARD_LL, is that right? */
HWND hwnd = FindWindow(NULL, "Vertices.exe");
HINSTANCE instance = (HINSTANCE)GetWindowLong(hwnd, GWL_HINSTANCE);
/** end part */
SetWindowsHookEx(WH_KEYBOARD_LL, LowLevelKeyboardProc, instance /** or NULL ? */, NULL);
}
回调定义(我在应用中有内容)
LRESULT CALLBACK LowLevelKeyboardProc(int nCode, WPARAM wParam, LPARAM lParam);
按下任意键时给出的值
nCode:0 | wParam:0x100 | lParam:0x18fe14
只有wParam在按键向上变为0x101(按键向下为0x100)
答案 0 :(得分:3)
KBDLLHOOKSTRUCT *kbdStruct = (KBDLLHOOKSTRUCT*)lParam;
:)
