Property wnd.IsAlive

---

Overload

Returns true if the window exists (the window handle is valid). Returns false if the handle is 0 or invalid. Invalid non-0 handle usually means that the window is closed/destroyed.

public bool IsAlive { get; }

Property Value

bool

Remarks

Calls wnd.Is0 and API IsWindow. Although a wnd variable holds a window handle, which is like a reference to a window, it does not prevent closing that window and making the handle invalid. After closing the window, the OS can even assign the same handle value to a new window, although normally it can happen only after long time.

note

Use this carefully with windows of other applications or threads. The window can be closed at any moment, even when your thread is still in this function.
