• Localization of accesskeys in internet explorer

  - by VikrantY

  We have an enterprise web application that we are converting from english to Thai. One area that has got us stumped is on the issue of "access keys". We use the "Accesskey" attribute in IE to provide short cuts to our buttons. However, how do we do this in Thai? Does HTML and IE support unicode access keys and if so how? Our application is IE specific, so any specific technology that IE uses is welcome.

• Qt C++ XML, validating against a DTD?

  - by Airjoe

  Is there a way to validate an XML file against a DTD with Qt's XML handling? I've tried googling around but can't seem to get a straight answer. If Qt doesn't include support for validating an XML file, what might be the process of implementing validation myself? Any good reference to start with in regards to validating XML against a spec? Thanks for the help!

• Need a good way to store data in a DB from a table on a webpage that can have N columns.

  - by Abe Miessler

  Users need to be able to add a specific type of column to an otherwise static table on my web page and then save the information they enter in there to the database. I've been told that in reality they will almost never go over 5 columns but I would rather support N. The columns will all be of the same datatype. My first thought was to have an XML column with the values from all added columns in there but I was curious if anyone else had come up with a better solution. Suggestions?

• Named parameters lead to inferior readability?

  - by Thomas Jung

  With named parameters like def f(x : Int = 1, y : Int = 2) = x * y your parameter names become part of the interface f(x=3) Now if you want to change the parameter names locally, you are forced to perserve the public name of the parameter: def f(x : Int = 1, y : Int = 2) = { val (a,b) = (x,y) a * b } If this a real problem? Is there a syntax to support this directly? Who do other languages handle this?

• Writing a batch file to delete files with wildcards

  - by iamthejeff

  I have multiple websites set up in the same folder, and I want to create a batch file that will delete the cache in each of them without having to add a new line for each site. For example I am using this: del /S /Q D:\www\site-name\cache\* Which works, but I have to add a new line for every site in D:\www. The del command doesn't support: del /S /Q D:\www\*\cache\* So what is a better way to do this?
