We have an ASP.NET application that manages it's own User, Roles and Permission database and we have recently added a field to the User table to hold the Windows domain account.

I think the line you need to add to your .emacs is is
(setq default-directory "C:/Documents and Settings/USER NAME/Desktop/" )
Emacs will start in your desktop that way, unless you have a file open. It will usually start in the same directory as the file in your current buffer otherwise. |
JavaScript uses a simple object literal:
var x = { intValue: 5, strValue: "foo" };
This constructs a full-fledged object.
JavaScript uses prototype-based object orientation and provides the ability to extend types at runtime:
String.prototype.doubleLength = function() {
return this.length *... |

If you need to do this on Win32 pre-Vista or Server 2008, look at the `GetMappedFileName(...)` function, which is one of the best kept secrets in Win32. WIth a little `C/C++-`*fu*, you can memory map a small portion of the file in question, and then pass that handle to this function.

#include will replace its line with the literal contents of the file. If the file does not end with a newline, the line containing the #include that pulled it in will merge with the next line. |
Use an std::set. Define a type for the 3d coordinate (or use a boost::tuple) that has operator< defined. When adding elements, you can add it to the set, and if it was added, do your processing. If it was not added (because it already exists in there), do not do your processing.

IMHO The biggest misconception about TDD is that: **time spent writing and refactoring tests would be time lost.** The thinking goes like "yeah, a test suite is nice, but the feature would be complete much faster if we just coded it".

As noted by others, it would be useful to be more specific. I don't think you can expect there to be a library that will generate ranges according to any arbitrary order on string you can come up with.

Ruby on Rails uses both prototype and Scriptaculous by default, as there is little overlap between the two. I've also used yui snippets in addition to that and have never had a problem. Load times are an issue, but the libraries are usually cached, so it's only on the first page loaded. |
