To clarify, W2k is probably pretty reliable now for the desktop, but the servers have a way to go. In addition to reliability issues, the resources required to do the same functions on the 2000 products (w2k, office 2K, access 2K) are much higher than the 97 and 4.0 versions. MS can't even keep their own sites going: http://www.zdnet.com/zdnn/stories/news/0,4586,2677896,00.html?chkpt=zdhpnews 01 Now I don't bash MS for a living, just as a hobby. They've been sliding steadily downhill since the 4.0 release. I provide computer services on MS and Novell networks for a living. I would not consider putting W2K servers into production until they are stabilized and still would not do so unless my client are planning a hardware upgrade as part of the process. We've seen too many black screens of death with W2K servers. The clients do appear more stable, but why sacrifice performance in a business environment when you gain nothing? I've used 4.0 without a crash for years. Why switch? It's faster and does everything I need. It will be interesting to see the Unix command-line loving community's reaction when MS releases their text mode server product. This will certainly interest the mouse-phobic. If I want USB for multimedia solutions, I'll probably do it under BeOS. Then again, I'll probably use firewire. (which should've been in windows instead of USB from the start.

download file from LocalFS
by Ulrich Wisser 24 Jan '01

24 Jan '01

Hello, my users are not allowed to access the whole LocalFS. Therefor I setup a proxy method to check their access rights. If they are allowed I would like to return the file. This is what I came up with: 1. Make the LocalFS accessible through PathHandler 2. The PathHandler DTML method checks the access rights 3. if a directory is accessed a listening is returned if a file is accessed the file is returned Now pleasse see my code: <h1>Path to handle <dtml-var path_to_handle></h1> <dtml-let user="AUTHENTICATED_USER.getUserName()"> <dtml-if "user in lfs.fileIds()"> <dtml-call "REQUEST.set('mylfs',lfs[user])"> <dtml-in path_to_handle> <dtml-call "REQUEST.set('mylfs',mylfs[_['sequence-item']])"> </dtml-in> <p>meta_type = <dtml-var "mylfs.meta_type"></p> <dtml-if "mylfs.meta_type != 'Local Directory'"> THE FILE SHOULD BE RETURNED HERE! <dtml-else> HERE COMES THE DIRECTORY INDEX. </dtml-if> <dtml-else> <dtml-raise type="No Access"> No access granted.<br> User: <dtml-var AUTHENTICATED_USER> </dtml-raise> </dtml-if> </dtml-let> When mylfs references a directory meta_type is 'Local Directory' but if mylfs references a file meta_type is 'File'. How can I let the user download the file?

Style guide?
by J B Bell 24 Jan '01

24 Jan '01

Having read the Python style guide (and having found it, if a bit confusing, at least not intolerably strict), I am now curious about what style people like to use in Zope. Are folders classes, or objects? In the examples in the Book, most of the folders are done in StudlyCaps, while the documents and methods are in mixedCase. Although, of course, index_html is under- score_separated. Aigh! Is there any consistent guide to this? I generally prefer good old underscores, having come from a Perl background. Looking on the web gives me the ZDP's style guide for their documentation, but not for Zope itself. Any guidance would be much appreciated. I hope I have not revived an old holy war. --JB

Re: Some help required but no sarcastic comments this time please

I understand your comments about sarcasm, but realize that this community is riddled with Unix bigots and just ignore it. Just listen to those willing to help. If you don't have to use MySQL, try either SQL Server or MS Access (small databases). See my pages on Zope NT SQL at http://techsite.tech-world.com/zopetips.htm for NT specific info. I would also recommend NOT using Win9x for ANYTHING. I always use NT. Other than that, have you installed the Win32 python extensions? Not sure if these are required with mySQL as I haven't used it myself.

Dowloading images from another site with external method?
by Etienne Labuschagne 24 Jan '01

24 Jan '01

Hi all I have an external Python method in Zope that accesses a map server through an ActiveX connector. This map server creates a map and gives me the URL where I can download the map eg. "http:\\www.mysite.com\images:8081\img1234545.png" I want to download this image with the method, put it in a folder on my Zope server's disk, do some image processing with PIL and then upload it into my Zope site. My problem is that I don't know how to download the image from the URL above! I can have zope display it from that address, but that won't work as the map server eventually deletes the rendered maps (also I want to edit it first) I cannot use ftplib as the map server does not handle ftp requests, only http. I don't know how to use the httplib (or whatever) to download that image to my disk. Any help? Thanks Etienne Tel: (012) 348 4586 Cel: 082 442 8981 Fax: (012) 361 8355
