Hello everyone,
Does anyone know how to simulate mouse move and mouse click using code::blocks as a platform and Windows 7

Thank you in advance!

Try to control your mouse for 5 seconds:

#include <windows.h>

int main()
{
    MOUSEINPUT mouseDown {2, 5, 0, MOUSEEVENTF_MOVE, 0, NULL};
    INPUT mouse {INPUT_MOUSE, mouseDown};
    for(int i = 0; i < 500; ++i) {
        SendInput(1, &mouse, sizeof(mouse));
        Sleep(10);
    }
}

Edit: in case you have an outdated compiler:

#include <windows.h>

int main()
{
    MOUSEINPUT mouseDown;
    mouseDown.dx = 2;
    mouseDown.dy = 5;
    mouseDown.mouseData = 0;
    mouseDown.dwFlags = MOUSEEVENTF_MOVE;
    mouseDown.time = 0;
    mouseDown.dwExtraInfo = NULL;
    INPUT mouse;
    mouse.type = INPUT_MOUSE;
    mouse.mi = mouseDown;
    for(int i = 0; i < 500; ++i) {
        SendInput(1, &mouse, sizeof(mouse));
        Sleep(10);
    }
}

it gives me some errors like:

mousemove.cpp: In function 'int main()':
error: 'MOUSEINPUT' was not declared in this scope
error: expected ';' before 'mouseDown'
error: 'INPUT' was not declared in this scope
error: expected ';' before 'mouse'
error: 'mouse' was not declared in this scope
error: 'SendInput' was not declared in this scope

Did you include windows.h?

[Nanyo]

yes I just copied your code and pasted it in my codeblocks, but it doesn't work even with your second code

[MiiNiPaa]

Looks your MinGW version does not work properly.
try to add one define before inclusion:

#define _WIN32_WINNT 0x0500
#include "Windows.h"

thank you it worked now, I have one more question
how to simulate a click :)

[MiiNiPaa]

Well, page on MOUSEINPUT tells that you need to send message with MOUSEEVENTF_LEFTDOWN flag set in dwFlags. Then you need to send message with MOUSEEVENTF_LEFTUP flag set to simulate button release;
http://msdn.microsoft.com/en-us/library/windows/desktop/ms646273%28v=vs.85%29.aspx

#define _WIN32_WINNT 0x0500
#include <windows.h>

int main()
{
    MOUSEINPUT click[2] {{0, 0, 0, MOUSEEVENTF_LEFTDOWN, 0, NULL},
                         {0, 0, 0, MOUSEEVENTF_LEFTUP, 0, NULL}};
    INPUT mouse_click[2] {{INPUT_MOUSE, click[0]}, {INPUT_MOUSE, click[1]}};
    SendInput(2, mouse_click, sizeof(mouse_click[0]));
}

Paste this in your IDE, move mouse to the Windows Start button and press F9.

I have a problem again
error: expected '}' before ';' token
error: cannot convert 'INPUT (*)[2] {aka tagINPUT (*)[2]}' to 'LPINPUT {aka tagINPUT*}' for argument '2' to 'UINT SendInput(UINT, LPINPUT, int)'

[Nanyo]

my compiler is:

=== TDM-GCC Compiler Suite for Windows ===
--- GCC 4.6 & 4.7 Series ---
*** Standard MinGW 32-bit Edition ***

Ah, remove & in the SendInput function. And add another closing bracket at the end of mouse_click definition. I fixed my previous code.

thank you!
You are amazing!!!! :D
