• dotted stroke in <canvas>

  - by Sam

  I guess it is not possible to set stroke property such as CSS which is quite easy. With CSS we have dashed, dotted, solid but on canvas when drawing lines/or strokes this doesn't seem to be an option. How have you implemented this? I've seen some examples but they are really long for such a silly function. For example: http://groups.google.com/group/javascript-information-visualization-toolkit/browse_thread/thread/22000c0d0a1c54f9?pli=1

• Create web application with ajax from the begining or add ajax later?

  - by klew

  I'm working on my first Ruby on Rails aplication and it's quite big (at least for me ;) - database has about 25 tables). I'm still learning Ruby and Rails and I never wrote anything in Javascript nor Ajax. Should I add Ajax to my application from the begining? Or maybe it will be better to add it latter? Or in the other words: is it (relatively) easy to add ajax to existing web application?

• How do I prevent use of beta classes from google guava library?

  - by mjlee

  We have been using Google collections in the production for several months. We would like to start using guava for additional functions. However, I'm afraid to bring guava into our product stack b/c some developers may start to use 'beta' classes. We have various unit-tests in our code but at this point, I prefer not to include 'beta' class b/c it is subject to change in the future. Is there any easy way to do detect if the project includes any 'beta' guava classes?

• How can I use the compile time constant __LINE__ in a string?

  - by John

  I can use __LINE__ as a method parameter just fine, but I would like an easy way to use it in a function that uses strings. For instance say I have this: 11 string myTest() 12 { 13 if(!testCondition) 14 return logError("testcondition failed"); 15 } And I want the result of the function to be: "myTest line 14: testcondition failed" How can I write logError? Does it have to be some monstrosity of a macro?

• Compare versions as strings

  - by Dmitriy

  Comparing version numbers as strings is not so easy... "1.0.0.9" "1.0.0.10", but it's not correct. Obvious way to do it properly is parse these strings, convert to numbers and compare as numbers. Is it other way to do it more "elegant"? For example, boost::string_algo...

• How do I make my java webservice client fetch and parse WSDL upon execution?

  - by ventolin

  I've created java webservices and clients using Netbeans. However, the clients seem to have the WSDL already 'built-in'. Is there an easy way of making my client fetch and parse the WSDL code upon execution, so that if the webservice moves to another server, the client is just invoked with a different commandline argument for where to find the webservice?

• Horizontal scrolling in a wx.RichTextCtrl

  - by Sam

  I have a RichTextCtrl created as follows: self.userlist = wx.richtext.RichTextCtrl(self, style=wx.TE_MULTILINE|wx.TE_READONLY|wx.HSCROLL) It all works fine, except for the wx.HSCROLL style. If I change the RichTextCtrl to a regular TextCtrl, it correctly horizontal scrolls on long lines, rather than wrapping, but on the RichTextCtrl it wraps regardless. Is there an easy way to make it scroll horizontally? (I do, unfortunately, need the RichTextCtrl's featureset for this object.)

  Is there a quick and easy way to backup both MS SQL 2008 and MySQL, all their databases? Right now I have a batch script that runs, but I have to manually add a database each and every time, and I'm sick of maintaining it.

Thank you.
