• Plone site files owner

  - by user308333

  Hello everybody, I accidentally changed owner of all files on my plone site to plone, and I don't know how to fix this without reinstalling site, which won't be acceptable. I have backup version which keeps default owners but it's changed in the meanwhile on the dafault site. Maybe rsync can sync only ownerships between these copies??? Any idea would be precious. Cheers

• What's your experience developing on Google App Engine?

  - by MrDatabase

  Is GQL easy to learn for someone who knows SQL? How is Django/Python? Does App Engine really make scaling easy? Is there any built-in protection against "GQL Injections"? And so on... I'd love to hear the not-so-obvious ups and downs of using app engine. Cheers!

• PHP: simple form encoding/decoding

  - by Lennart

  Hi guys, Probably, this question has been asked before, though, I'll ask it again. Currently, I'm facing a problem with form encoding.

• CollectionViewSource & Selective Column Display

  - by Berryl

  By selective column display i mean the following: a control shows a listing of widgets (WidgetVm.DisplayName), with the default display name being in English (WidgetVm.EnglishName), but with the option to show the widget in French (WidgetVm.FrenchName). There also sorting and filtering available, which is why CollectionViewSource seems ideal. I know you can have multiple views over the same source but I haven't figured out how to do this yet. Is that the right approach to solving this? How? Cheers, Berryl

  - by gotye

  Hey everyone, I am currently trying to create a subclass of UIImageView in order to make it download its image from server asynchronously ;) I tried to do it by myself but I haven't gone very far yet :D Anyway, I looked around here and found this : AsyncImageDownload I had a look at the code and the first which springs to mind is : why subclassing a UIView and not a UIImageView ?!?

• Error upgrading WSSF solution to VS 2010

  - by Mark Evans

  Hi I've recently installed VS2010 and I'm trying to upgrade a project that I created using VS2008 and WSSF (Web Service Software Factory). I've installed the 2010 version of WSSF and it's prerequisites. After upgrading, when I try to load the solution I get "blah.ssfproduct cannot be opened because its project type (.ssfproduct) is not supported by this version of the application". Absolutely no idea what to do :( Cheers Mark

• Reflection: Get FieldInfo from PropertyInfo

  - by Ed Woodcock

  Hi guys. I'm doing some dynamic code generation using Reflection, and I've come across a situation where I need to get the backing field of a property (if it has one) in order to use its FieldInfo object. Now, I know you can use .IsDefined(typeof(CompilerGeneratedAttribute), false); on a FieldInfo to discover whether it's autogenerated, so I assume there's a similar thing for Properties which auto-generate fields? Cheers, Ed

• Is there a way to click a link in Firefox and open a file in an existing VIM session?

  - by btelles

  Hi there, I know it's possible to open links in an html page (let's say, if you're using Firefox) with TextMate if the link has this format: <a href="txmt://open?url=file:///home/.../index.html.haml">View</a> But is it possible to do a similar thing with VIM? Perhaps like so: <a href="vim://open?url=file:///home/.../index.html.haml">View</a> Ideally this would use an existing VIM session. Cheers, Bernie

  With iOS4 coming out soon, I have already planned to include an iAd in a future update of an app of mine. I assume that this will make my app unusable for anyone on a firmware lower than 4.0. Is there a way to change that variables and the .xib file based on the user's firmware? Cheers.
