• How to get multiple counts with one SQL query?

  - by Crobzilla

  I am wondering how to write this query. I know this actual syntax is bogus, but it will help you understand what I am wanting. I need it in this format, because it is part of a much bigger query. SELECT distributor_id, COUNT(*) AS TOTAL, COUNT(*) WHERE level = 'exec', COUNT(*) WHERE level = 'personal' I need this all returned in one query. Also, it need to be in one row, so the following won't work: 'SELECT distributor_id, COUNT(*) GROUP BY distributor_id'

• Why cast null before checking if object is equal to null?

  - by jacerhea

  I was looking through the "Domain Oriented N-Layered .NET 4.0 Sample App" project and ran across some code that I do not understand. In this project they often use syntax like the following to check arguments for null: public GenericRepository(IQueryableContext context,ITraceManager traceManager) { if (context == (IQueryableContext)null) throw new ArgumentNullException("context", Resources.Messages.exception_ContainerCannotBeNull); Why would you cast null to the type of the object you are checking for null?

• Why does my Sharepoint page's custom content type change to "Page" when editing?

  - by Mobius

  I have a custom Sharepoint 2007 site definition with custom content types for the different page layouts. When editing a page using a custom layout from the main "View all contents" tree view, the page content type is fine, but if I view the page directly and edit it from there, the content type gets stripped and replaced with "Page." I can change it back by viewing and editing it from the main list, but not from its subsite home location.

• Is there a way to use rsync and exclude files greater than a certain size?

  - by milesmeow

  I've checked out the man pages and did some searching but can't find info on ways to have rsync skip files greater than a certain size. We're doing rsync to an offline location and when someone puts a hug video file, the rsync jobs run into work hours. I've looked at the 'exclude' syntax and didn't see anything for excluding based on file size. Can I do it with rsync or should I look for other offline synching alternatives?

• jquery - if else if?

  - by YesThatsRight

  I've been trying to figure out the syntax for an if / else if statement in jquery, but googling gives me mixed messages... There are some sites that say I need a plugin, and others that suggest that it's already possible. Trying those suggestions give me jquery errors in the jquery.js file, so I'm wondering, do I need a plugin or not? Does someone have an example of an if () { //do something } else if () { //do something else } else { //do something } in jquery?

• JQuery - .position isn't returning offset relative to parent.

  - by Spines

  I'm using .position to find the offset of where the element is relative to the parent, however it seems to be returning a value that is the offset from some parent up the ancestor tree. I have a button, and its wrapped withing a div and its the only element of that div. The div is floated right. .position is returning a value like {left:780, top:370}, when the true value should be around {left:200, top:0}. I'm using jquery 1.4

• jQuery Prototype conflict, alternative solutions

  - by lbolognini

  I have a problem as I'm conditionally including the Prototype-based Lightbox script for IE6 as it works better than the jQuery plugin. Of course the two libraries conflict but the official solution is not really feasible for me as i would have to replace tons of $ with the alternative no-conflict syntax. Is there any other solution for me, keeping in mind that in my case it would be easier to have Prototype work nicely with jQuery than the other way around?
