Detecting if a window is minimized

Hi.
I am having trouble to detect something.
If you want to know if a window is hidden you could use 'IsWindowVisible', easy to use.
But if you want to know if a window is minimized (and not your own window) it is harder to do and I don't know how.
I have tried something like this but it wont work:

Code:

---

if ( SendMessage ( FindWindow ( "TheOtherWindowClass", "TheOtherWindowCaption" ), WM_SIZE, ( WPARAM ) SIZE_MINIMIZED, 0 ) )

---

Could someone please help me?

****, I just found it, I have searched very long on the forums and couldn't find it, now I just found it.

Code:

---

if ( IsIconic ( FindWindow ( "TheOtherWindowClass", "TheOtherWindowCaption" ) ) )

---

That will do it, if I just searched longer there wouldn't be need for this thread, a moderator may delete this.
