• Active User Tracking, PHP Sessions

  - by Nik

  Alright, I'm trying to work on a function for active user counting in an AJAX based application. I want to express the below SQL Query in correct syntax but I'm not sure how to write it. The desired SQL Query is below: SELECT count(*) FROM active WHERE timestamp > time() - 1800 AND nick=(a string that doesn't contain [AFK]) Now, I do understand that time() - 1800 can be assigned to a variable, but how is timestamp > variable and nick that doesn't contain a string written in SQL?

• IgnoreArguments including an Action<T>

  - by James L

  I'm probably missing something obvious here, so apologies in advance! Using Rhino Mocks, how do I set an expectation that a method taking an Action will be called, but I want to use IgnoreArguments. Obviously I can't specify null as that isn't an Action, and I dont want any meaningless code in the test. As I said, it's probably obvious by the syntax is eluding me at the moment!

• Change/Update a pane using python wx.AUI

  I'm using wx.AUI and having a bit of a problem managing panes. Once you have created a new pane using AddPane(), what is the syntax to update or change the pane? I've seen the SetPane command but I can't find any examples. Can someone direct me to an example? Or perhaps it makes sense to use some command to delete the pane and create a new one? Thanks in advance for your time.

• Is DateTime.ParseExact() faster than DateTime.Parse()

  - by Nassign

  I would like to know if ParseExact is faster than Parse. I think that it should be ParseExact since you already gave the format but I also think all the checking for the Culture info would slow it down. Does microsoft say in any document on performance difference between the two. The format to be used is a generic 'yyyy/MM/dd' format .
