We use this DCOracle version under Solaris 2.7 with Oracle 8.1.6 without problem. Especially, the "@host" works. Thus, it does not look like a DCOracle problem. Dieter

However, my ZServer recovered without any problem. As your message indicates, it simply closed the channel and continued to work. Dieter

Tom Deprez writes: > ... nested Z SQL method call ... I do not understand fully, what you want to do. But the following FAQ may also be your problem: Z SQL methods do *NOT* use the DTML namespace for parameters. You must either pass the parameters explicitly: <dtml-in "sql_method(param1=val1, ..., paramn=valn)"> or put the parameters in the REQUEST object: <dtml-call "REQUEST.set('param1', val1)"> .... <dtml-call "REQUEST.set('paramn', valn)"> <dtml-in sql_method> Dieter

Under Unix, your code may look at the "last access time" (or universally the "modification time"). In Python, you can use the function "os.stat" to obtain this time. Dieter

Re: [Zope] Backslash as line continuation in C (Unix)

Is there any gcc option that recognizes > backslashes are line-joining characters? Or is there another character used > in gcc for joining lines? Any other suggestions? Backslashes *ARE* line-joining characters for gcc -- without any options! I expect, that your backslashes are not immediately followed by "\n" (not "\r\n"!). Then, they would not be "line joining"! This very easily happens, if you transfer a Windows source onto a Unix system. I do not know, which editor you are using under Linux. If you use "vim", then you would not see the "\r" preceeding the "\n" but you would see a "textmode" in the status line. Use ":set notextmode" and then write the file back. This would remove the "\r". You may use the "tr" utility, too, for the "\r" removal, once you determined that this indeed is the problem. Dieter

img tag dtml question
by Jason Cunliffe 13 Sep '00

13 Sep '00

Hello Can anyone see why under 2.2.0 this is wrong ? ............................................................................ /images [folder] 7Dlogoicon_gif [gif image file object] /deliverables/standard_html_footer [DTMLmethod] <dtml-with /images> <a href = /deliverables> <dtml-var "7Dlogoicon_gif.tag(border = 0)"> </a> </dtml-with> </body> </html> This worked many times before ok under 2.1.6 on another site with similar technique. But now I am getting >>> invalid syntax, for tag <dtml-var "7Dlogoicon_gif.tag(border=0)">, on line 3 of standard_html_footer When I try removing the outer quotes <dtml-var 7Dlogoicon_gif.tag(border = 0)> >>> Document Template Parse Error >>> invalid parameter: " = 0)", for tag <dtml-var 7Dlogoicon_gif.tag(border = 0)>, on line 3 of standard_html_footer Simply, I need to make sure that every document I put in '/deliverables' can have a localized standard HTML footer with an icon which will link users back up to /deliverables. The icon needs to have a 'border = 0' attribute. help much appreciated thanks - Jason ________________________________________________________________ Jason CUNLIFFE = NOMADICS.(Interactive Art and Technology).Design Director

Ownership and security
by Andy McKay 13 Sep '00

13 Sep '00

How do I remove ownership from a product, ie: make it unowned? I have some dtml that works quite happily on unowned objects, but at soon as they become owned I get into a whole whack of problems with getUserById. Of course I would really love to have ownership work, but I know its hell trying to explain it on a mailing list. -- Andy McKay, Developer. ActiveState.

Re: [Zope] How to Pass values to a DTML method ??

Evan Simpson writes: > .... extended-attribute syntax > (foo-name-name="x" instead of foo="_[_[x]]"). HELP! I am sure, that such an extended attribute syntax would cause hundreds of messages in this list. I hope, it will not get adopted. > I have considered proposing that we graft <dtml-let>'s capabilities onto the > other tags, so that we could write stuff like: > > <dtml-var set-foo="getFoo()" var=foo set-param1=" 'text' " set-param2="id"> That is better. Only: What does the "var=foo" mean? The thing that should be rendered? Then (with respect to this), the current syntax is clearer. Or: Should this be equivalent to: <dtml-var "getFoo(_.None,_,param1='text', param2=id)>? Then, it is not at all obvious. "getFoo" seams to be called explicitly without parameters. Clearer would be: <dtml-var getFoo set-param1="'text'" set-param2="id"> Dieter
