Return Value

---

See the Return Values section in GetParent in the Platform SDK.

Remarks

The GetParent function returns a pointer to the immediate parent (if it exists). In contrast, the GetParentOwner function returns a pointer to the most immediate parent or owner window that is not a child window (does not have the WS_CHILD style). If you have a child window within a child window GetParent and GetParentOwner return different results.
