    We can use the following function.
    BOOL SHDoneButton(
      HWND hwndRequester,
      DWORD dwState
    );
    This function is provided for applications that need to dynamically show or hide the OK button based on the state of the application.
    dwState : [in] Specifies the button state. SHDB_SHOW, hide the OK button; SHDB_HIDE, hide the OK button.
    This function returns TRUE if it is successful and FALSE if it fails.
    Code Example:
    ::SHDoneButton(m_hWnd,SHDB_HIDE); (MFC)
    or
    BOOL SHDoneButtonExample(HWND hWnd, BOOL fShow)
    {
        if (fShow) {
            // show the done button when window becomes foreground
            return SHDoneButton(hWnd, SHDB_SHOW);
        } else {
            // hide the done button when window becomes foreground
            return SHDoneButton(hWnd, SHDB_HIDE);
        }
    }
