CWnd* GetWindow( UINT nCmd ) const;
nCmd
Specifies the relationship between CWnd and the returned window. It can take one of the following values:
| Value | Meaning |
| GW_CHILD | Identifies CWnd's first child window. |
| GW_HWNDFIRST | If CWnd is a child window, returns the first sibling window. Otherwise, it returns the first top-level window in the list. |
| GW_HWNDLAST | If CWnd is a child window, returns the last sibling window. Otherwise, it returns the last top-level window in the list. |
| GW_HWNDNEXT | Returns the next window on the window-manager's list. |
| GW_HWNDPREV | Returns the previous window on the window-manager's list. |
| GW_OWNER | Identifies CWnd's owner. |
Searches the window manager's list for a window. The window-manager's list contains entries for all top-level windows, their associated child windows, and the child windows of any child windows. The nCmd parameter specifies the relationship between CWnd and the returned window.
Identifies a window. The value is NULL if the function reaches the end of the window-manager's list or if nCmd is invalid.
The returned pointer may be temporary, and should not be stored for later use.
