Games often receive keyboard input (along with input from game controllers and other intput devices) via DirectX. Defining WINVER = 0x0500 before including “windows.h” ensures that it includes anything included up to this version of Windows.

Line 23 must appear before line 24 because the “windows.h” header file is responsible for providing the definition of the INPUT structure, but it only does so if it knows it’s compiling for versions of Windows later than version 0x0500 (when the INPUT structure was presumably first introduced).

The usual reason that people see this particular error is either that the first of the following two lines (lines 23 and 24 of my code above) has been omitted, or that they are both included but in the wrong order: It should be possible to use another compiler, but maybe some tiny modifications could be required?) What C compiler are you using? (I used gcc.Have you modified the code in any way, no matter how small and seemingly insignificant?.I have come across that error before, but never with this version of the code. Here’s a complete main.c example using the second (unicode) form of SendInput: If that’s not the solution, let me know and I’ll see if I can work out why it’s not working for you. If you don’t set WINVER before including windows.h, gcc thinks you want to compile a program that will also be compatible wiith older versions of Windows that didn’t support SendInput etc.

Basically, it makes sure that windows.h will include all the relevant stuff. That’s why the WINVER definition line must come before windows.h is inluded. However, the definitions are dependent on the versions of Windows that your compiling for. The SendInput function (and some related stuff) is defined in a header file that gets included by windows.h. Are you using MinGW too?ĭid you definitely include both of the following lines at the start of your program? No, you shouldn’t need to use the VC++ compiler. Here’s a screenshot of the console window where I compiled and ran the program.Īs soon as I ran the program in the console window, I switched the focus to a Notepad window where the simulated keystroke typed a character, as shown in the following screenshot. Ip.ki.dwFlags = KEYEVENTF_KEYUP // KEYEVENTF_KEYUP for key release Ip.ki.wVk = 0x41 // virtual-key code for the 'a' key Ip.ki.wScan = 0 // hardware scan code for key This structure will be used to create the keyboard follows so that SendInput gets defined when windows.h

Windows 2000 and later, WINVER needs to be set as Because the SendInput function is only supported in 5 seconds for the A key to be magically pressed. Written by Ted Burke - last updated 17-4-2012 keystroke.c - Pauses, then simulates a key press When you run this program, it simply waits 5 seconds and then simulates a press and release of the “A” key on the keyboard. This program is a simple example of using the Win32 SendInput function to generate a simulated keystroke.
