  • Python Copy Through Assignment?

    - by Marcus Whybrow
    I would expect that the following code would just initialise the dict_a, dict_b and dict_c dictionaries. But it seams to have a copt through effect: dict_a = dict_b = dict_c = {} dict_c['hello'] = 'goodbye' print dict_a print dict_b print dict_c As you can see the result is as follows: {'hello': 'goodbye'} {'hello': 'goodbye'} {'hello': 'goodbye'} Why does that program give the previous result, When I would expect it to return: {} {} {'hello': 'goodbye'}

    - by Alan Seiden
    I want to assign a background color to my programmatically created Dojo DataGrid's header row. I've tried to override the defaults by adding .dojoxGridHeader or .dojoxGrid-Header to my style sheet, but these have no effect. Is there another way, such as with a Dojo event or property? If my style sheet is the only way to go, am I using the wrong class? Thanks! Alan

  • HTML table with fixed headers?

    - by Cheekysoft
    Does anyone know a cross-browser CSS/Javascript technique to display a long html table such that the column headers stay fixed on-screen and do not scroll with the table body. Think of the "freeze panes" effect in excel. I want to be able to scroll through the contents of the table, but to always be able to see the column headers at the top.

    - by EddieCatflap
    Myself and one other person co-created a website for a freelancing artist. For simplicity I mean that I purely developed the site code whilst the domain and hosting setup and content were created by the other creator. Who, in effect, owns the intellectual property here? Or does the person that the site was created for own rights to the site and content once it has been declared 'live'?

  • How to start/stop CrossSlide (jQuery)

    - by Alex
    I found that CrossSlide causes video playback on the same page to stutter quite badly. My thought was to have the cross slide effect on the same page stop or pause during video play back, annd then start again when video stops. Id doesn't look like there is any start stop function included. Does any one know how I might be able to accomplish this? Thanks.

  • How do I deny access to invalid web subdomains with .htaccess?

    - by Gravitas
    The following .htaccess file does not work: SSLrequireSSL RewriteEngine on RewriteCond %{HTTP_HOST} !^secure\.neuralfutures\.com [NC] RewriteRule (.*) - [F] I'm trying to prevent access to anything but "https://secure.neuralfutures.com/docs/", i.e. "https://www.neuralfutures.com/docs/" will fail. I also seem to be running into caching issues: if I upload the new .htaccess with CuteFTP, then do a file refresh in FireFox, it doesn't seem to have any effect on the output at all. I can tell this because if I comment out SSLrequireSSL, it still disallows a http:// request.
