Contiune keyboard working while hooking


Contiune keyboard working while hooking



I'm learning recently how to hook APIs and I started with keyboard calls. I set the hook with


"SetWindowsHookEx(WH_KEYBOARD_LL, LowLevelKeyboardProc, 0, 0);"



and everything is working as i want but...



Hooking is capturing keyboard and kinda blocking it - so as i want only to get informations that keys are used but dont wanna change the way they'r working i used


"keybd_event(p->vkCode, 0, 0, 0);"



and here appears another "but"... This function as it's simulation of key press it going to be hooked again what i do NOT want.



Is there any solution to get information about keyboard using without blocking the work of it?





WH_KEYBOARD_LL not blocking keyboard

WH_KEYBOARD_LL





DO NOT call keybd_event() from inside the hook. Let the hook do what it needs and then call CallNextHookEx() before exiting, and the key event will be delivered to the target normally. And FYI, the info that WH_KEYBOARD_LL gives you tells you whether the key event was simulated or not, so you can ignore events from keybd_event() and SendInput()

keybd_event()


CallNextHookEx()


WH_KEYBOARD_LL


keybd_event()


SendInput()





im stupid... Thanks a lot @RemyLebeau ;) it's working perfectly... i had "short if" in return with CallNextHookEx() and i suppose it didnt get to NextHook ;)

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select. As a result it does't select my result or anything (besides being "successful"). Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...

Opening a url is failing in Swift

Opening a url is failing in Swift breakpointing inside the callback and logging success shows false. I added itms-apps to my plist: LSApplicationQueriesSchemes and put this in my app delegate: func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool { return true } func moreTapped() { let url = NSURL(string: "itms-apps://itunes.com/developer/quantum-productions/id979315877") if #available(iOS 10.0, *) { UIApplication.shared.open(url! as URL, options: [:], completionHandler: {(success: Bool) in }) } else { UIApplication.shared.openURL(url! as URL) } } Are you testing on a real device? – rmaddy Jun 21 at 23:57 I try on a device, get "Cannot Connect to App Store".
