HWND CeGetWindow(
HWND hWnd,
UINT uCmd
);
Parameters
- hWnd
Handle to a window. The window handle retrieved is relative to this window, based on the value of the uCmd parameter. - uCmd
Specifies the relationship between the specified window and the window whose handle is to be retrieved. This parameter can be one of the following values.Value Description GW_CHILD The retrieved handle identifies the child window at the top of the z-order, if the specified window is a parent window; otherwise, the retrieved handle is NULL. The function examines only child windows of the specified window. It does not examine descendant windows. GW_HWNDFIRST The retrieved handle identifies the window of the same type that is highest in the z-order. If the specified window is a topmost window, the handle identifies the topmost window that is highest in the z-order. If the specified window is a child window, the handle identifies the sibling window that is highest in the z-order. GW_HWNDLAST The retrieved handle identifies the window of the same type that is lowest in the z-order. If the specified window is a topmost window, the handle identifies the topmost window that is lowest in the z-order. If the specified window is a child window, the handle identifies the sibling window that is lowest in the z-order. GW_HWNDNEXT The retrieved handle identifies the window below the specified window in the z-order. If the specified window is a topmost window, the handle identifies the topmost window below the specified window. If the specified window is a child window, the handle identifies the sibling window below the specified window. GW_HWNDPREV The retrieved handle identifies the window above the specified window in the z-order. If the specified window is a topmost window, the handle identifies the topmost window above the specified window. If the specified window is a child window, the handle identifies the sibling window above the specified window. GW_OWNER The retrieved handle identifies the specified window's owner window, if any. This flag will not retrieve a parent window.
Return Values
A valid window handle indicates success. NULL indicates that no window exists with the specified relationship to the specified window. To get extended error information, call IRAPISession::CeGetLastError and IRAPISession::CeRapiGetError.
