The 'flags' work as documented. The limitation is that you are using the Community Edition.
From the Docs:
For the Community Edition the GUI elements can not be changed, i.e. the preview has always a toolbar, rulers, scrollers and a statusbar. The open, save, grid and help buttons are not available, the other buttons of the toolbar can not be made invisible. In addition embedding the preview is not supported by the Community Edition. The only flags accepted by the Community Edition are VPE_DOCFILE_READONLY and VPE_FIXED_MESSAGES.
HTH,
Terry
