Is it a bug to pass a single-element array to SendInput?

Given the following code void foo() { INPUT input{}; input.type = INPUT_MOUSE; input.mi.dwFlags = MOUSEEVENTF_LEFTDOWN; SendInput(1, &input, sizeof(input)); input.mi.dwFlags = MOUSEEVENTF_LEFTUP; SendInput(1, &input, sizeof(input)); }; is it a bug to pass a single-element array to SendInput in consecutive calls? This seems to be perfectly supported by the documentation. Short answer: Maybe. Longer answer: It depends. To see what it depends on, and when this matters, it helps to understand, why SendInput was introduced into the Windows API: For one, it consolidates the keybd_event and mouse

Automating Key Presses with SendInput

When I attempt to use SendInput to send single key presses, and combined keypresses, I can't get my program to hold the keyboard button until commanded to be released. With the code below I am ables to send the character 'a' , and 'A' , by hitting shift first. However, I cannot get it to hold the 'a' button in perpetuity. public static void KeyDown() { SwitchWindow(Process.GetProcessesByName("notepad").FirstOrDefault().MainWindowHandle); INPUT[] inputs = new INPUT[1]; KEYBDINPUT kb = new KEYBDINPUT(); //Set up generic keyboard event inputs[0].type = INPUT_KEYBOARD; kb.wScan = 0; // hardware

Why do some applications not accept some sendkeys at some times

This is an issue I've ran into before, but I've always given up solving the problem and worked out a work around. Not today (hopefully). I'm trying to make a bot for the classic Doom II. I want my bot to have access to the main menu which is accessed via the escape key. Naturally I tried: sendkeys.send("{ESC}") No luck. But then something weird happened. I accidently ran the code when I was already on the menu... and it closed the menu (which is normal if you press escape on the menu). So clearly Doom II listens to Sendkeys. I've since tried sendinput, postmessage, and simulateinput. None have

C++ move mouse in windows using SetCursorPos

问题 I created a device similar to a wiimote and i want to use it as a mouse in windows (8.1). The device connects over tcp to a c++ win32 program on my windows computer and sends the position where the mouse cursor should move. I am using the SetCursorPos function to set the position, which works great to control most programs. But when I try to control for example the task manager, the cursor doesn't move anymore. When I switch from the task manager back to some other program it works again. I

SendInput() for keyboard - only lowercase

I have following code: INPUT Input = { 0 }; Input.type = INPUT_KEYBOARD; Input.mi.dwFlags = KEYEVENTF_EXTENDEDKEY; Input.ki.wVk = 'A'; // tried 0x41, ( UCHAR )VkKeyScan( 'A' ) SendInput( 1, &Input, sizeof( INPUT ) ); but it generates me only 'a'. How to force it to generate upper case as well? Thanks. tobi EDIT: some modifications according to rodrigo answer in comments. INPUT Input = { 0 }; // shift key down Input.type = INPUT_KEYBOARD; Input.ki.wVk = VK_LSHIFT; SendInput( 1, &Input, sizeof( INPUT ) ); // 'a' key down Input.type = INPUT_KEYBOARD; Input.ki.wVk = 'A'; SendInput( 1, &Input,

Using SendInput to send unicode characters beyond U+FFFF

问题 I'm writing an onscreen keyboard similar to the one in Windows 8. I have no problem sending most of the characters I need using Win32's SendInput. The problem is when it comes to the new Windows 8 Emoji's. They start at U+1F600 using the Segoe UI Symbol font. Using Spy++ on the Windows 8 onscreen keyboard I get the following output for all Emoji glyphs. <00001> 000C064A P WM_KEYDOWN nVirtKey:VK_PACKET cRepeat:1 ScanCode:00 fExtended:0 fAltDown:0 fRepeat:0 fUp:0 <00002> 000C064A P WM_CHAR

Sending a Keyboard Input with Java JNA and SendInput()

问题 I'm interested in interacting with the OS with java in this case windows 7 and want to emulate some keystrokes (e.g. CTRL + V) on a low level. First of all i know java is a bad choice but its my best programming language and i know its possible. Additionally i know awt.robot exists but its too high level for me (i really need the driver level). I'm asking this question because I really want to understand jna and after watching 20 code examples im still having problems. A code example for a
