Linux implements threads by processes that share memory and other resources. "ps" is still a bit stupid and does not visualize that they are threads rather than normal (full blown) processes. Dieter

Shane, You are DA MAN. That getPhysicalPath() & unrestrictedTraverse() methods work perfectly, even with SiteAccess installed. Thank you very much.

Store object2.getPhysicalPath(), which returns a tuple, in object1. To find object2 again, call object1.unrestrictedTraverse(stored_physical_path). Note that this only works in Zope 2.2.x+.

[newbie] sqltest question
by Martin Fekete 11 Jan '01

11 Jan '01

documentation says that sqlvar support expressions <dtml-sqlvar Variable|expr="VariableExpression"> and this works <dtml-sqlvar "'%'+arg+'%'" type=string> but documentation also says that sqltest support expressions <dtml-sqltest Variable|expr="VariableExpression"> so this should work <dtml-sqltest "'%'+arg+'%'" type=string column=arg> but it's not working ... any ideas ? thanks Martin Fekete

Re: [Zope] Help getting zope to do frames!

To properly reference your frames by their absolute urls, instead of this: <frame name="A" src="<dtml-var top>"> <frame name="B" src="<dtml-var main>"> Try this: <frame name="A" src="<dtml-var "top.absolute_url()">"> <frame name="B" src="<dtml-var "main.absolute_url()">"> -PSJ

Help getting zope to do frames!
by Scott Chapman 11 Jan '01

11 Jan '01

I am trying to get some frames to work where you can load a url and have a frame around it. I created a folder called test. I tried loading http://ipaddress/test and I get a recursion of frames and have to stop it loading. Here's the contents of the test folder. I'm very new to Zope and HTML so I'm probably missing something which should be obvious but I've been trying this for quite a while and can't figure it out. Can someone help me get this working? I want this to be set up so that I can open a URL and have the frame automatically loaded around it. Depending on the URL, a different frame will be loaded. It seems this is something Zope should be ideal for. Inside test are 3 DTML methods and 2 DTML documents: DTML Methods: id: standard_html_header title: Standard Html Header <html><head><title>Frames in Rows</title></head> <frameset rows="65,*"> <frame name="A" src="<dtml-var top>"> <frame name="B" src="<dtml-var main>"> </frameset> id: standard_html_footer title: Standard Html Footer </HTML> id: index_html title: index <dtml-var standard_html_header> <dtml-var standard_html_footer> DTML Documents: id: main title: Main Frame Contents <html><head><title>Main Frame Contents 1</title></head> <body> <h1>Main Frame Contents 1</H1> </body> </html> id: top title: top_frame <html><head><title>Top page of Frame</title></head> <body> <h1> This goes in the top frame</H1> </body> </html> Thanks! Scott.
