Is HWND visible?

Question

These damned users and their minimized windows.

In C #, if I have an HWND window, is there a way to find out if this is visible on the desktop?

Answer 1

The GetWindowPlacement function returns a WINDOWPLACEMENT that has a showCmd field:

Sets the current window display state.

The details of this are read as if you were setting the state of the window, but I suspect this is because they were copied from another place and not updated.

Answer 2

Here is the Visible property, but it checks the visibility flag, it does not tell you whether the window is closed by another window or from the screen, etc. This is much more complicated. Raymond Chen has a few tips:

Answer 3

 bool isHwndVisible = Control.FromHandle(handle).Visible
