C#

private void btn_Click(object sender, EventArgs e)
 {
 if (e.Button == System.Windows.Forms.MouseButtons.Right){MessageBox.Show("Right click");}
 if (e.Button == System.Windows.Forms.MouseButtons.Left){MessageBox.Show("Left click");}

Google "global event hooks in windows"

I have tried this. in global hooks events the mouse events and key press events are triggered based on the check box click events.

Do you mean when the user performs a MouseClick on some other Application's UI, with your Application not having focus ?

Thanks for your reply, I need to capture an image on each mouse click and keyboard press events.

an "image" of what ? "image" implies bit-map / screen-shot. please answer the question about whether or not you are trying to get Events outside your running Application.

I am trying to capture screen-shots on each mouse events and key press events and I am not trying to get events outside of application.

Just to make clear: You want to take screenshots only when clicking within the form of your own application?

Renjith_R 2-Feb-16 9:50am

Not exactly, I am trying to create an exe. when i run that exe it should click all the screen-shots of each mouse events and key press events in the particular machine.Not only with in the form of my application.

Alright - but then you actually do want to get events outside your application. Because if you click somewhere on the screen, outside the form of your application, there's no "normal" way in .NET to get these events. Thats why Sinisa Hajnal suggested global event hooks, which is the way to go. If you tried something like that and it didn't work then you didn't to it right ;-) I'll see if I can come up with a solution, but no promises.

Thank you so much for your quick reply. I need to check the global event hooks deeply.Please let me know if you find any alternate solutions.

Thanks in advance

I think you'll find a solution in this CodeProject article:
Processing Global Mouse and Keyboard Hooks in C#[^]

It's most up-to-date project can be found on GitHub:
gmamaladze/globalmousekeyhook - C# - GitHub[^]

I took a glance at it and it looks really easy and straight forward.
