How to click a link/button using C#

[letmetry]

Hi all,

Is there any way to click a link or button present on the desktop using C#.

[letmetry]

Let me make the scenario more clear....

I have written the code to open the 'System properties'(sys dm.cpl) of my computer.

Now i like to know whether there any code available to click on the various tabs/buttons/links present in the system properties page.

If possible please provide me with some sample codes, so that i can understand better.

Thanks.
