I have been searching on google and msdn trying to figure this out and got really confused. What I am trying to do is make a windows application that simulates mouse clicks after I hit a certain button. I want the program to make the mouse click anywhere and continue to click even if the program is minimized, until I hit the button that tells it to stop. I have the C++ code for it, which is very simple: //Simulate left mouse click mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, X, Y, 0, 0); Is there any equivalent C# code? Is there a way to port this C++ code into my C# program? I am completely new to .NET, sorry for the noob questions! Thanks

Yes, you can import this function into your C# program. Here's an example:

Awesome! That worked perfectly. Thanks a lot. :D

What about right clicks?

replace left with right in the call to mouse_event() maybe ?

Be careful with an application like this.
I have written some GUI test harnesses that had functionality like this.
It can be difficult to make them work in a way that handles a lot of situations gracefully.

Here are some notes of interest if you plan on expanding your tool.
screen resolution changes, time between keypresses and click messages, lost messages, etc.

A good help is if there is a hook that you can use to check if the keypress, or click was successful.

I'm trying to use this class, but no matter what values I use for X and Y, the simulated click always happens wherever the mouse cursor is.

What is the point of the X and Y if not to tell the function the location of the mouse click

      //Call the imported function with the cursor's current position      int X = Cursor.Position.X;      int Y = Cursor.Position.Y;

They're setting the X and Y to the current mouse position. Set the values to whatever you want.

I did change these values. It still doesn't work.

I'm having the exact same problem. I can't figure out how to set the coordinates for x and y; no matter what values I use, the mouse stays in the same position, I used the right button down and up to test this...
