Send mouse Click message [closed]

Question

How we can make mouse click event in a certain position without moving mouse(I mean that make computer think a position is clicked with mouse) with C++

Answer 1

The SendInput function in windows API will get you started. Have a look at the following link for the definition of the method,its input parameters and return values :

You can follow the links in the page to know more about the structures and data-types used in the function.

Update : You can start with something like this

#include<Windows.h>
int main()
{
    INPUT input;
    input.type=INPUT_MOUSE;
    input.mi.dx=0;
    input.mi.dy=0;
    input.mi.dwFlags=(MOUSEEVENTF_ABSOLUTE|MOUSEEVENTF_MOVE|MOUSEEVENTF_RIGHTDOWN|MOUSEEVENTF_RIGHTUP);
    input.mi.mouseData=0;
    input.mi.dwExtraInfo=NULL;
    input.mi.time=0;
    SendInput(1,&input,sizeof(INPUT));
    return 0;
}

This will automatically move your mouse to the top left corner of the screen and make a right-click. Now, if you mean to make a click somewhere on the screen without moving your mouse, I think that is not possible using SendInput(). You do not need to worry about moving the mouse as your program will do it by itself. That is what the 'MOUSEEVENTF_MOVE' flag tells the program to do. If you do not use the flag, then the click will take place at the current position of your mouse.
