Overview
The GetParentWindow function returns the parent (owner) window handle for a provided window handle.
Syntax/Parameters
Syntax
handle = GetParentWindow ( handle hWindow );
Parameters
hWindow
A handle representing a window.
Return Value
Returns a handle of the parent window or NULL_HANDLE on error. Use the GetLastError function to retrieve a formatted error code. On error, the underlying error number will be a Windows API error code.
This function typically fails for one of the following reasons:
– The provided hWindow parameter is invalid.
– The window is a top-level window that is unowned or does not have the WS_POPUP style.
– The owner window has WS_POPUP style.
Remarks
If the window is a child window, the return value is a handle to the parent window. If the window is a top-level window with the WS_POPUP style, the return value is a handle to the owner window.
