When you get a C# Warning CS0067, the MSDN documentation tell you to insert a “#pragma warning disable 0067”, but Trevor Robinson has a better solution at C# Warning CS0067: The event ‘event’ is never used – Trevor’s Dev Blog – Site Home – MSDN Blogs:
Since the event is never used, make the event explicit, or even throw an exception in the add clause of the event.

When you (or the one that installed SQL Server 2008) forgot to add an administrator, it is still possible to add one.
The How do you add an administrator user to SQL Server 2008 question on Server Fault pointed me to the right page SQL Server 2008: Forgot to add an Administrator account? by Chris Randall.
Note that you might want to run SQL Server in Single User Mode; the first answer on the above question doesn’t mention that, but the second does (and pointed me to Chris Randall’s page).

I’m a fan of ISO 8601, as it is a universal way of expressing dates and times (no more MDY confusion ).
I wrote about using ISO 8601 in batch-files and with Google Calendar before.
Now it is time to give you a simple C# example.
When you realize that XML uses ISO 8601 for their date and time formats, the .NET conversion is very easy:
using System;
using System.Xml;
public class Test
{
public static void Main()
{
string Iso8601DateTime =
XmlConvert.ToString(DateTime.Now, XmlDateTimeSerializationMode.Local);
Console.WriteLine(Iso8601DateTime);
}
}
I wrote about ideone.com before: it is an excellent place to run sample C# code (and other languages).
When running this on ideone.com, you can see their local server time in ISO 8601 format.
Cute :-)
BTW: There are more ways to run your C# code online.

New versions sometimes means the loss of features.
Starting with Google Chrome 10, the “Open frame in new tab” option in the context menu was removed (“Reload frame”, “View frame info” and “View frame source” are still there though).
The removal has been reported as a bug by Michael Schramm on December 10, 2010, but no action from the Chromium nor Chrome teams yet.
But shortly after the removal, two Chrome extensions appeared:
Though they both work very well, I like the second one more because it has slightly more options (it is based on the first one).
Note that when you install these extensions, you have to reload a tab when you want to use the new functionality offered by the extension on that tab.

It looks like when you install Windows Media Player in Window 7, it will expose your media library for DLNA access by default for any user that chooses “quick” settings.
This even when you have not turned on media streaming, or not enabled the “Automatically allow devices to play my media” (this link has some screenshots on those settings).
I know few users who go the whole nine yards around those “quick” settings, so pretty much any Windows 7 user has their media library exposed as DLNA in your Home or Work networks (DLNA seems disabled on Public networks by default).
This is both a pollution of your DLNA space (for instance making it more difficult from your digital TV to to select the correct DLNA source), and an exposure. Any malware in your network might so some discovery (and yes, truckloads of PC’s in Work or Home networks have such malware running).
Though searching for “Winodws 7” “Disable DLNA” returns few good results, the actual trick is easy:

There are many ASP.NET HttpRequest properties.
Sadly, the MSDN documentation does not have many examples telling you which property maps to which portion of the URL.
So it usually is a big fight extracting the sub portions you need.
Luckily, Steve Lautenschlager has the How Do I Get Paths and URL fragments from the HttpRequest object? article online.
The article has a table with the properties and portions of the URL that end up in those properties.
Really neat, as it saves a lot of time.

Thanks to Martin Kulov’s Blog: Any CPU vs. x86 vs. x64 I got a reference to a great article explaining this in more detail.
The obvious points are 1., 2. and 3., but it is 4..7 that makes the article really worth reading.

When you install VMware Server 2.0 on Windows Server 2008, Internet Explorer will give you a warning that it cannot load the local VMware Server console web-site at https://servername:8333.
The reason is that the security certificate is self-signed by the local machine, not by a trusted CA.
Internet Explorer does not allow you to add that CA, but you can from within Windows Explorer.
The Removing the VMWare Server SSL Certificate Trust Warning article explains how.
Note that on x64 Windows Server 2008 systems, the VMware Server certificate by default is in the C:\Program Files (x86)\VMware\VMware Server\SSL directory.
Finally, you will need to add https://servername:8333 to the trusted sites in Internet Explorer.

With the gaining popularity of Desktop systems with multi-core processors, it becomes interesting to use multi-core CPU guests in VMware workstation.
Right now, Intel Core i3 through i7 processors can provide from 2 to 6 cores, some cores even supporting hyper-threading and providing 12 virtual cores using a single physical processor.
Does it make sense now to run all your VM guests with multiple virtual cores / vCPUs?
On the VMware forums and knowledge base, there are many threads and articles with information on vCPUs.
The consensus is that VMware workstation can take longer to schedule a synchronized set of cores for a VM than VMware ESX(i) has, and the host OS needs CPU cycles too.
The reason is that VMware workstation needs the underlying host Operating System for that, whereas ESX(i) has it’s own kernel.
In the VMware workstation 7 beta, under some circumstances, adding more vCPUs actuall made the guest run slower (this has been fixed).
You need to be careful when vCPUs in the guest compete with pCPUs in the host; it can lead to frequent freezes in the guest.
The rule of the thumb is that you should not use more than 50% of the host pCPU cores as guest vCPUs.
So the best is to start with one (1) vCPU, and only crank it up when needed.
Take into account however that for Windows XP you will need to change the HAL to support multiple CPUs, which can be a pain.
In some cases it can pay off big to increase the number of vCPUs, especially when they are actually used.
Another thing you need to be aware of is that modern CPUs van vary their clock speed, now even depending on the number of cores used. In the past this had influences on timekeeping, but not so any more with modern Core i# processors.
Finally, with the increase of hard-disk space, people use snapshots more often. This can dramatically decrease the performance, as the number of open files per VM increases.
I hope this helps you choosing the number of vCPUs in your guest.
–jeroen
Note: Both VMware ESXi and VMware Workstation 7.1+ can even support vCPU with multiple cores to help cope with guest OS CPU licensing limitations: set the cpuid.coresPerSocket property in your vmx for that.
