Simulate Mouse Presses C++

Name: Anonymous 2011-10-28 17:29

I'm trying to write a program that at the underlying level simulates mouse events. The basic example of what I want it to do is move the mouse, press the mouse down, move the mouse again, and let mouse up to draw a line in say, MS Paint... or the Doodle or Die application (http://doodle.no.de);

The problem I run into is that neither Doodle or die nor MSPaint seem to accept that I am issuing mouse down events... except that MSPaint works fine if I am using a non drawing tool such as the Eraser or Selection.


int main(int argc, char *argv[])
{
    tagINPUT inp;
    tagMOUSEINPUT mi;
    DWORD moveFlags = (MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_MOVE);
    DWORD downFlags = (MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_LEFTDOWN);
    DWORD upFlags = (MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_LEFTUP);

    mi.dwFlags = moveFlags;
    mi.dx = 5000;
    mi.dy = 2000;
    inp.type = INPUT_MOUSE;
    inp.mi = mi;

    SendInput(1, &inp, sizeof inp);

    tagMOUSEINPUT mi2;
    tagINPUT inp2;

    SetCursorPos(1500, 500);

    mi2.dwFlags = downFlags;
    inp2.type = INPUT_MOUSE;
    inp2.mi = mi2;
    SendInput(1, &inp2, sizeof inp2);

    SetCursorPos(500,200);
    mi2.dwFlags = upFlags;
    inp2.type = INPUT_MOUSE;
    inp2.mi=mi2;
    SendInput(1, &inp2, sizeof inp2);
   
    return 0;
}


This was just really shit shod together code to try to get something working.

Basically, if MSPaint is up and I have the erase selected, it will erase a line from those 2 points like it should...but if I have the brush selected it will do nothing. Doodle or die (I believe is flash) does the same thing and will not draw.

I'm using windows.h's SendInput, however I have tried the deprecated mouse_event and it does the same thing.

Any ideas on how to get it to actually accept my leftDown and leftUp events?

Trying to make a Runescape bot?

Nah, tryin to make an application that reads in an image file and then draws to the doodle or Die game (doodle.no.de).

The game doesn't accept just a click, so you have to move the cursor a minute amount to get it to draw, then release the mouse.

I've found something online about how I need to use 0x201 and 0x202 instead of mouseeventf_leftdown/up, but they don't seem to work either.

Again though, all works in MSPaint if im using the erase tool, but not the brush tool.

do yourself a favour and download an open source keylogger

Keyloggers record incoming stuff, they don't send commands.  And those that do generally use mouseeventf_leftdown and leftup to simulate a click.  This works fine for me, I can simulate a click in anything but a drawing canvas. I can select tools around the drawing canvas, manipulate the menu in the program, highlight stuff in Chrome, but nothing will draw into the program's draw area

This is how I've done it:

1) Make a global variable

INPUT leftClickInputStructure[2];

2) Do this once at the beginning of the program

memset(leftClickInputStructure, 0, 2*sizeof(INPUT));
leftClickInputStructure[0].type = INPUT_MOUSE;
leftClickInputStructure[1].type = INPUT_MOUSE;
leftClickInputStructure[0].mi.dwFlags = MOUSEEVENTF_LEFTDOWN;
leftClickInputStructure[1].mi.dwFlags = MOUSEEVENTF_LEFTUP;

3) Then sending a click is just this:

SetCursorPos(xcoord, ycoord);
SendInput(2, leftClickInputStructure, sizeof(INPUT));

SendInput doesn't change the INPUT array you pass to it, so you can just reuse the same one each time.

Use AutoHotkey FFI to callback into your program,
returning commands to be interpreted:

http://www.autohotkey.com/docs/commands/DllCall.htm
http://www.autohotkey.com/docs/Functions.htm#NumPut
http://www.autohotkey.com/docs/commands/MouseClickDrag.htm

The script part:

TYPE_MOUSEMOVE := 0
TYPE_MOUSEDRAG := 1
TYPE_QUIT := 2

!w::
  HerpData := 0
  VarSetCapacity(HerpData, 666, 0)

  DoQuit := 0
  DoTick := 0
 
  While (0 = DoQuit)
    {
      NumPut(DoTick, HerpData, 4)
      Res := DllCall("Herp.dll\callback", UInt, &HerpData, Cdecl)
     
      if (TYPE_MOUSEMOVE = NumGet(HerpData, 0))
        {
           CoordMode Mouse, Screen
           MouseMove NumGet(HerpData, 8), NumGet(HerpData, 12), 0
        }

      if (TYPE_MOUSEDRAG = NumGet(HerpData, 0))
        {
           CoordMode Mouse, Screen
           MouseClickDrag Left, 0, 0, NumGet(HerpData, 8), NumGet(HerpData, 12), 2, R
        }

      if (TYPE_QUIT = NumGet(HerpData, 0))
        {
           DoQuit := 1
        }

      DoTick := DoTick + 1
    }
return

The DLL part:
[/code]
/* gcc -shared -o Herp.dll Herp.c */
#include <stdlib.h>
#include <stdint.h>
#include <windows.h>

enum HerpTypes
{
  TYPE_MOUSEMOVE = 0,
  TYPE_MOUSEDRAG,
  TYPE_QUIT
};

struct HerpData
{
  int32_t type;
  int32_t tick;
  int32_t out_x;
  int32_t out_y;
} __attribute__((packed));

void callback (struct HerpData *data)
{
  switch (data->tick)
    {
    case 0:
      data->type = TYPE_MOUSEMOVE;
      data->out_x = 200;
      data->out_y = 200;
      break;

    case 1:
      data->type = TYPE_MOUSEDRAG;
      data->out_x = 100;
      data->out_y = 0;
      break;

    case 2:
      data->type = TYPE_QUIT;
      break;
    }
}
[/code]

Find one of those programs that records and plays back mouse events like WinMacro:
http://senthilthecoder.com/software/winmacro/download.html

Inspect the source and modify to your needs.

Totally unnecessarily overcomplicated way of doing it.

As far as I can tell, WinMacro uses the Journal record and playback hooks:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms644959%28v=vs.85%29.aspx#wh_journalplaybackhook
Reading its source will not help with synthesizing input events.

HEY GUYS, INSTEAD OF USING THE SIMPLE, EASY TO UNDERSTAND SOLUTION GIVEN TWO POSTS UP, LET'S FIND AN OPEN SOURCE PROGRAM THAT DOES SOMETHING SORT OF LIKE WHAT WE WANT AND COMB THROUGH ITS DOZENS OF SOURCE FILES UNTIL WE FIND THE PART THAT DOES IT

>Use AutoHotkey FFI to callback into your program,
AutoHotkey is a script. Native code can be embedded with 100% speed and no dependency on Autohotkey.
(i have nothing against AH,since i use it for small scripts for my emulators)
