• How many indexes will actually get used?

  - by Ender

  I'm writing a page that does very simple search queries, resulting in something like: SELECT * FROM my_table WHERE A in (a1, a2, a3) AND B in (b1, b2) AND C in (c1, c2, c3, c4) AND And so on for a variable number of columns, usually ~5. If I create a separate index for each column (one for A, one for B, one for C, not (A,B,C)), will all of them be used in the above query?

• What font and size is used in Windows 7 File Explorer Tree

  - by Stefan Koell

  I am having a hard time to find out which font is used by the Win 7 File Explorer in the tree view on the left hand side. Better, of course, would be if I can programmatically find out which the right font is (C#). I searched the Windows 7 design guidelines but this particular scenario is not listed (at least I couldn't find it). So anyone good with fonts?

• Is Microsoft Workflow Foundation really used ?

  - by ereOn

  Today, I had a training on "Microsoft Workflow Foundation". While I think the idea is neat, I still see it as a Proof Of Concept and not as a real-life solution. Building an entire application without having to type a single line of code (or only a few of them) seems just wrong. Have you ever used this technology and if so, can it really fit to big company projects ? What drawbacks/advantages have you got using it ?

• Data Structure Used For SMS Messages In Android

  - by Greenhouse Gases

  Does anybody know what data structures are used to the store messages in an SMS client app, and whether there is an existing API for this. I was perhaps looking at implementing a link list for the purpose but if the work has already been done in an API then perhaps it would be unnecessary to commit time to the task that could be spent programming other parts. Many thanks

• Cakephp: how do I know what route was used

  - by Jason

  So I am a total cakephp newb and one of the first things I expected to see basic info about each page request logged. More specifically, what route data including what controller/method is being used. Obviously I did not find what I was expecting and about the only kind of meaning info I can find is from the apache logs. What I expected was to see something similar to first log entry for a rails app request. Does cakephp not log this kind of data?
