sendinput event

[MichaelC1989]

this is my code:

I am trying to make it do a right mouse button down and drag and then at the end of the drag, let go of the right mouse button. For some reason it doesn't work! It's for my project to control a video game mouse look event. I am trying to make it turn right by so and so degrees.

Did I do something wrong here?

thx!

	INPUT input;

	input.type = INPUT_MOUSE;
	input.mi.dx = 0;
	input.mi.dy = 0;
	input.mi.dwFlags = MOUSEEVENTF_RIGHTDOWN;
	input.mi.time = 10;
	input.mi.time = 0;
	SendInput(1, &input, sizeof(input));
	
	Sleep(50);
	input.type = INPUT_MOUSE;
	input.mi.dx = 100;
	input.mi.dy = 0;
	input.mi.dwFlags = MOUSEEVENTF_MOVE;
	input.mi.time = 10;
	SendInput(1, &input, sizeof(input));

	Sleep(50);
	input.type = INPUT_MOUSE;
	input.mi.dx = 0;
	input.mi.dy = 0;
	input.mi.dwFlags = MOUSEEVENTF_RIGHTUP;
	input.mi.time = 0;
	SendInput(1, &input, sizeof(input));

Pass in an array of INPUT structs and make a single call to SendInput().

I don't know how to do that, could you show me up please?

Have you tried mouse_event instead ? Simulate click down then move pointer and simulate click up

					// Bring Window On Top
					HWND window = FindWindow(NULL, "Window Title");
					ShowWindow(window, SW_RESTORE);
					SetForegroundWindow(window);

					// Rect Location
					RECT rect;
					GetWindowRect(window, &rect);

					// Set Cursor
					SetCursorPos(rect.right - 50, rect.bottom - 100);

					// Click once
					mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);

					// Set Cursor Second Location
					SetCursorPos(rect.right - 100, rect.bottom - 200);

					// Release click
					mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);

I had cases when sendinput failed but mouse_event didn't

[MichaelC1989]

that works alright, if i give the 3 commands separately yes, but it's different from giving all 3 commands in one sendinput, i dont know why. That's why i am trying to figure it out

[eclessiastes]

probably because u use the same INPUT input. you could do INPUT input1 for one task, INPUT input2 for another etc. I had cases when SendInput didn't work for virtualized exe in different session id, since then i always use mouse_event

When you pass the array of items, you need to set input.mi.time to an increasing value for each of the array entries.

how long?

This is what I have now, but it seems there is some problem with building the array. I get this error message:

argument of type "INPUT (*)[3]" is incompatible with parameter of type "LPINPUT"

#include <iostream>
#include <windows.h>
#include <ctime>
using namespace std;

void main()
{
	Sleep(3000);

	INPUT input[3];

	input[0].type = INPUT_MOUSE;
	input[0].mi.dx = 0;
	input[0].mi.dy = 0;
	input[0].mi.dwFlags = MOUSEEVENTF_RIGHTDOWN;
	input[0].mi.time = 10;
	
	input[1].type = INPUT_MOUSE;
	input[1].mi.dx = 100;
	input[1].mi.dy = 0;
	input[1].mi.dwFlags = MOUSEEVENTF_MOVE;
	input[1].mi.time = 10;

	input[2].type = INPUT_MOUSE;
	input[2].mi.dx = 0;
	input[2].mi.dy = 0;
	input[2].mi.dwFlags = MOUSEEVENTF_RIGHTUP;
	input[2].mi.time = 0;

	SendInput(3, &input, sizeof(input));


	return;
}

Try

	INPUT input[3] = {0};

	input[0].type = INPUT_MOUSE;
	input[0].mi.dx = 0;
	input[0].mi.dy = 0;
	input[1].mi.time = GetTickCount();
	input[0].mi.dwFlags = MOUSEEVENTF_RIGHTDOWN;
	
	input[1].type = INPUT_MOUSE;
	input[1].mi.dx = 100;
	input[1].mi.dy = 0;
	input[1].mi.time = GetTickCount();
	input[1].mi.dwFlags = MOUSEEVENTF_MOVE;

	input[2].type = INPUT_MOUSE;
	input[2].mi.dx = 0;
	input[2].mi.dy = 0;
	input[1].mi.time = GetTickCount();
	input[2].mi.dwFlags = MOUSEEVENTF_RIGHTUP;

	SendInput(3, &input, sizeof(INPUT));
}

Also, search this forum for SendInput and bing or google for "SendInput Examples C++".
