HHOOK g_hKeyboard=NULL;void CHOOKDlg::OnOK() {this->SetHook(m_hWnd);}LRESULT CALLBACK KeyboardProc(int code, // hook codeWPARAM wParam, // virtual-key codeLPARAM lParam // keystroke-message information){if(VK_F2==wParam){// SendMessage(g_hWnd,WM_CLOSE,0,0);UnhookWindowsHookEx(g_hKeyboard);}return 1;}void CHOOKDlg::SetHook(HWND hwnd){ g_hKeyboard=SetWindowsHookEx(WH_KEYBOARD,KeyboardProc,GetModuleHandle("HOOK.exe"),0);}同一段代碼我將g_hKeyboard=SetWindowsHookEx(WH_KEYBOARD,KeyboardProc,GetModuleHandle)中的WH_KEYBOARD改成了13,是可以屏蔽所有程序的按鍵的,按F2時卻卸載不了鉤子了!改為WH_KEYBOARD_LL時,告訴我WH_KEYBOARD_LL沒聲明,郁悶!明明有的呀!
用以下的代碼,發現只能是在屏蔽本程序里按鍵,切換到其它地方,就不行了!應該怎么改？
