Get which process/window is actually visible in C#

[John the Gr8]

Hello,

I have a list of all open windows, the ones in the windows taskbar. What I want to do is to remove the ones that are not visible from the list.
What I mean is, if a window is hidden by another one, it should not be in my list.

I've been searching google for the past two days without success...

Any ideas?

I can get the location and size of each process, so getting the last time a process was used/idle time would work too...

What do you mean by "visible"? It has focus? Or it can be seen by the user?

If it can be seen by user... If it's hidden by another window or not...

I take a screenshot of full screen, and I want to know which windows are visible in this screenshot...

Afaik every visible window has a title. Check if the window has a title?

That's not what I mean, read carefully...

Do you mean you want to get a list of all processes that have created a window and then remove the ones that are minimized? If so, I guess that this could be achieved with the use of winapis.

Example:

So, chrome, mozilla (3 windows), skype and steam are open, but only one window of mozilla and steam are visible...

Try checking which windows are minimized.

just found that one myself. Thanks, though!

To be honest, I don't think it's possible.

The only way I see you would have to do it is to compare the size and window locations of every window.
Along with the Z index the window has.

But I have no clue how to access the Z index.
