Abstract ZClasses and containing classes
by Brian and JoAnn Burton 11 Sep '00

11 Sep '00

Scenario: here is a hierarchy of ZClasses. AbsDogPoundOrganization - abstract class ForProfitOrganization - subclass of AbsDogPoundOrganization NonProfitOrganization - subclass of AbsDogPoundOrganization Now I want AbsDogPoundOrganization to contain the class of Location (not an abstract class). First, what is the correct way to define an abstract ZClass. Do you make one that has no constructors? The problem I see is that then the subclasses of AbsDogPoundOrganization don't allow me to create instances of Location within them.

ZClass property sheets and lists of values
by Brian and JoAnn Burton 11 Sep '00

11 Sep '00

Is there a way to have 2 property sheets in a ZClass where one property in one sheet uses a property in another sheet to fill out its list? This way, I can manage who can control what is in the list. How do I refer to the property that contains the list? I tried things like ../othersheet/listproperty but that did not work.

ZServer Statistics
by Demos Economacos 11 Sep '00

11 Sep '00

Is there way to determine how many (and which)pages ZServer serves? I am running ZServer as my primary server. What kind of statistics should I be looking for? For example should I be concerned about how long it takes to load pages, and how long users stay on a specific page etc? I am new to website management and would appreciate any and all suggestions. Thanks in advance. Demos __________________________________________________ Do You Yahoo!? Get Yahoo! Mail � Free email you can access from anywhere! http://mail.yahoo.com/

Yes, although I wrote the hacked DTD for the mode, I am no DTD guru. Maybe, there is a way to do it with a better DTD. There was once a rumour that there was going to be an XML compliant specification of DTML. This would presumably make the problem go away. It is a long time since I heard any more about this.

I use HTML Tidy from Dave Ragget [1]. I have, of course, got Emacs code to tidy up and indent HTML code in the buffer currently being edited. Ii is only a few lines but I will make it available if there is interest. I also had wondered whether it would be worthwhile binding HTML Tidy into Zope. The way dynamic web sites generate HTML code out of bits, often leaves the resulting HTML code illegible and, not incidentally, syntactically incorrect. --- Alastair Footnotes: [1] http://www.w3.org/People/Raggett/tidy/

Re: [Zope] Import from file via management-interface

>I found it very disturbing having to get my .zexp exports >into the subdirectory 'import' of the server and then using >the management-interface to do the actual import. I found it inconvenient, too. (Not disturbing, though.) And I had to implement my own uploading scheme via web. But as anything that is put into the file system, I thought that there must be some security reason. At least I know that's why the Extensions folder is there. Is this (existence of import folder) really a shortcoming of Zope, or is there some security reason why .zexp cannot be uploaded directly from browser? Can someone somehow write a destructive external method, and then upload it via .zexp? regards, Hung Jung _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Oooh, now there's an interesting thought... One would like to - but there often aren't enough hours in the day. Actually one is frequently lucky to even get the option to try to pick something at all, never mind doing the research - some combination of "we've already got it" or "its "free" (it never is)" or "its got microsoft written on the outside of the box" or "we already know <insert name of something relevant>" tends to get in the way. Sometimes you get lucky, and in the meantime you take an interest in the stuff going on around you so that you can make a bid for use of a better mousetrap when the opportunity arises...

Import from file via management-interface
by Tino Wildenhain 11 Sep '00

11 Sep '00

Hi all, I found it very disturbing having to get my .zexp exports into the subdirectory 'import' of the server and then using the management-interface to do the actual import. So I patched ObjectManager and the compaining dtml-file. Please check them out (included in the mail, sorry for the traffic) if I should post them to the collector.

Using Chinese Characters
by Kelvin Cheong 11 Sep '00

11 Sep '00

i was wondering how i can use chinese characters with Zpe on Linux. does anyone know how? According to my "mild" research so far, i found out that Big5is a 2-byte code and is a part of ISO-10646/Unicode. It also seems to be the de-facto for traditional chinese characters. There're also Unicode CJK and GB. But GB is for China, which uses simplified chinese characters. And CJK includes both Big5 and GB. The most puzzling thing to me is how all this works. Do i need a special browser, font server, Zope products? And when i can display chinese characters using any one of the standards, how am i going to input it in the first place? And last but not least, how does all this ascii and unicode conversion work together? I've seen a couple of chinese sites running on Zope, and was wondering if I could get some help in here. Anyone have any ideas? VCN - The Leader In Corporate Communication Solutions Visit our website at http://www.vcn.com.my. or http://www.vcnlinux.com
