[英]sending simultaneous keyboard events with SendInput on windows in C++
I want to simulate keyboard presses in C++ using SendInput , while single buttons work, trying to send keys simultaneously (shortcuts) doesn't work. 我想使用SendInput模拟C ++中的键盘按键,而单个按钮有效,但尝试同时发送按键(快捷键)却不起作用。
I tried everything, but nothing works, if I send VK_LWIN alone it shows up, but couldn't combine keys simultaneously. 我尝试了所有操作,但没有任何效果,如果我单独发送VK_LWIN ,它会显示,但无法同时组合键。
here's my code: 这是我的代码:
#include <windows.h>
#include <stdlib.h>
#include <stdio.h>
void setInput(INPUT * inp,uint index, WORD keycode,BOOL kUp);
void showRun();
int main(void)
{
showRun();
return 0;
}
void setInput(INPUT * inp,uint index, WORD keycode,BOOL kUp)
{
inp[index].type = INPUT_KEYBOARD;
inp[index].ki.wVk = keycode;
inp[index].ki.wScan = MapVirtualKey(keycode, 0);
inp[index].ki.time = 0;
inp[index].ki.dwExtraInfo = 0;
if (kUp == 1)
{
inp[index].ki.dwFlags = KEYEVENTF_KEYUP | KEYEVENTF_EXTENDEDKEY;
}else
{
inp[index].ki.dwFlags = 0 | KEYEVENTF_EXTENDEDKEY;
}
}
//this doesn't do anything
void showRun()
{
INPUT *inp = (INPUT*) malloc(sizeof(INPUT) * 4);
memset(inp,0,sizeof(INPUT));
setInput(inp,0,VK_LWIN,0);
setInput(inp,1,VK_RBUTTON,0);
setInput(inp,2,VK_RBUTTON,1);
setInput(inp,3,VK_LWIN,1);
SendInput(4,inp,sizeof(INPUT));
free(inp);
}
while this works fine: 虽然可以正常工作:
void showStart()
{
INPUT *inp = (INPUT*) malloc(sizeof(INPUT) * 2);
memset(inp,0,sizeof(INPUT));
setInput(inp,0,VK_LWIN,0);
setInput(inp,1,VK_LWIN,1);
SendInput(2,inp,sizeof(INPUT));
free(inp);
}
Thanks in advance for any tip. 在此先感谢您的提示。
啊,愚蠢的我,我应该使用VkKeyScan('r')而不是VK_RBUTTON了,它现在可以工作了!
