1. create a csv container object (like a StringBuilder in C#)
2. Loop through the strings you want to add appending a comma after each one
3. After the loop, remove that last superfluous comma.
Code sample:
public string ReturnAsCSV(ContactList contactList)
{
StringBuilder sb = new StringBuilder();
foreach (Contact c in contactList)
{
sb.Append(c.Name + ",");
}
sb.Remove(sb.Length - 1, 1);
//sb.Replace(",", "", sb.Length - 1, 1)

Aside from a tiny bit of testing, I have never used Vista, but overall I have heard many more bad reports than good regarding Vista. I don't think that hardware will be an issue (Intel Core Duo T9300, 4GB RAM, 256MB NVIDIA) in terms of performance. I am just uneasy about using Vista for my main dev system given its history, when I have the opportunity to keep on using XP.
So is there anyone here who has experience with both Vista and XP as the OS on your dev machine? If you could choose one over the other, which would you go with? I will need to use Visual Studio 2003/2005/2008, SQL Server 2005, Virtual Machines, Office, as well as lots of multi-tasking and multi-tab web browsing.
(Note: I am not interested in Microsoft-bashing. If you haven't used Vista but have just heard bad things about it then you have the same level of experience as me and you probably shouldn't be answering the question). | xp | windows-vista | operating-system | microsoft | null | null | open | Vista or XP for Dev Machine

The latest disaster was not grokking that I need to actually push results inside a mock object of IEnumerable<T>...

IAnimal mockRhino = mockery.DynamicMock<IAnimal>();

- Had to consume the IEnumerable<IAnimal> results into IList<IAnimal>, I understand this puts the results for checking onto the heap
- Had to setup the contents of the results ... I understand this as well, but my main point is to test that Zoo.Animals is returning IEnumerable<IAnimal>, and even better, that we're using "yield return" inside

It works fine when I connect directly to the company network in the office. However, it does not work when I connect to the network remotely over a VPN.
When I start Xming when connected remotely none of my terminal windows are displayed.
I think it may have something to do with the DISPLAY environment variable not being set correctly to the IP address of the laptop when it is connected.
I've noticed that when I do an ipconfig whilst connected remotely that my laptop has two IP addresses, the one assigned to it from the company network and the local IP address I've set up for it on my "local network" from my modem/router.

I am unsure if I should do this, and I need to keep 2005 on this machine for the foreseeable future in order to test our application easily.

From what I've seen on the MVC site and various blogs, it seems that a lot is still in flux, making it so that upgrading to the latest MVC version would likely require a lot of code changes.
Compared to WebForms, is it worth getting the MVC model at the expense of likely having to do re-writes later just to comply with the latest version? I ask this especially in terms of doing something that will be used, not just if I should try it out. | 3 |

environment. Thankfully this is not production ;) The problems started
when the disk with the SQL Server databases and search index ran out
of space. Following this, the search service would not run and search
settings in the SSP were not accessible. Reclaiming the disk space did
not resolve the issue. So rather than restoring the VM, we decided to
try to fix the issue.
We created a new SSP and changed the association of all services to
the new SSP. The old SSP and it's databases were then deleted. Search
results for PDF files are no longer appearing, but the search works
fine otherwise. MySites also works OK.
Following the implementation of this change, these problems occur:
1) An audit failure message started appearing in the application event
log, for 'DOMAIN\SPMOSSSvc' which is the MOSS farm account.
Event Type: Failure Audit
Event Source: MSSQLSERVER
Event Category: (4)
Event ID: 18456
Date: 8/5/2008
Time: 3:55:19 PM
User: DOMAIN\SPMOSSSvc
Computer: dastest01
Description:
Login failed for user 'DOMAIN\SPMOSSSvc'. [CLIENT: <local machine>]
2) SQL Server profiler is showing queries from SharePoint that reference the old
(deleted) SSP database.
So...
* Where would these references to DOMAIN\SPMOSSSvc and the old SSP
database exist?
* Is there a way to 'completely' remove the SSP from the server, and
re-create? The option to delete was not available (greyed out) when a
single SSP is in place. | sql-server | database | sharepoint | search | ssp | null | open | MOSS SSP problem - Failed database logons from deleted SSP

I would like to be able to drag, say, a tree node from a treeview in my winforms app into a specific location in the hosted web page and have it trigger a javascript event there.

One solution, I suppose, would be to bite the bullet and write a custom browser plugin in the form of an activex control, embed that in the location I want to drop to and let that implement the needed drag\drop interfaces.
Would that work?

Is there a way to make the conversion case insensitive or add a custom mapping class or extenstion method into the mix so that I can specify what the string should look like in more detail.
Reasons for doing so might be in order to supply a nicer naming convention inside some new funky C# code in a system where the data schema is already set (and is being relied upon by some legacy apps) so the actual text in the database can't be changed. | 0 |

The reason for that is that the current developers are heavy on Java but felt the need for a MVC-style language for some future web development projects. Personally, I'm coming from the design/usability world, but as I take more "front-end" responsibilities I'm starting to feel the need for learning a language more intensively so I can code some logic but especially the front-end code for my UIs and stuff.
I've been trying to get into Python/Django personally, but just never invested too much time on it. Now that my company is "jumping" into Grails I bought the "Agile Web Development with Rails (3rd Ed - Beta)" and I'm starting to get into RoR. I'd still like to learn Python in the future or on the side, but my biggest question is:
- Should I be learning RoR, and have a more versatile language in my "portfolio", knowing that my RoR knowledge will be useful for my Grails needs as well??
-OR-
- Should I just skip RoR and focus on learning Grails that I'll be needing for work soon, and work on learning RoR/Django (Ruby/Python) later?
Basically the question revolves around the usefulness of Grails in a non-corporate setting and the similarities between Rails and Grails. (and this, while trying to avoid the centennial discussion of Python vs Ruby (on Rails) :) hehe)

===
I have a situation where I want to add hours to a date and have the new date wrap around the work-day. I cobbled up a function to determine this new date, but want to make sure that I'm not forgetting anything.
The hours to be added is called "delay". It could easily be a parameter to the function instead.
Please post any suggestions. [VB.NET Warning]
Private Function GetDateRequired() As Date
''// A decimal representation of the current hour
Dim hours As Decimal = Decimal.Parse(Date.Now.Hour) + (Decimal.Parse(Date.Now.Minute) / 60.0)
Dim delay As Decimal = 3.0 ''// delay in hours
Dim endOfDay As Decimal = 12.0 + 5.0 ''// end of day, in hours
Dim startOfDay As Decimal = 8.0 ''// start of day, in hours
Dim newHour As Integer
Dim newMinute As Integer
Dim dateRequired As Date = Now
Dim delta As Decimal = hours + delay
''// Wrap around to the next day, if necessary
If delta > endOfDay Then
delta = delta - endOfDay
dateRequired = dateRequired.AddDays(1)
newHour = Integer.Parse(Decimal.Truncate(delta))
newMinute = Integer.Parse(Decimal.Truncate((delta - newHour) * 60))
newHour = startOfDay + newHour
Else
newHour = Integer.Parse(Decimal.Truncate(delta))
newMinute = Integer.Parse(Decimal.Truncate((delta - newHour) * 60))
End If
dateRequired = New Date(dateRequired.Year, dateRequired.Month, dateRequired.Day, newHour, newMinute, 0)
Return dateRequired
End Sub
