You heard.
I've done a bit of MVC in my time but Neville (who knows more than I do about Oracle but less than I do about MVC) just told me about the ActionName attribute. Here's the lowdown: http://haacked.com/archive/2008/08/29/how-a-method-becomes-an-action.aspx.
That is all.
I just got this error when trying to add an Administration Console User to TFS 2010 installed on Windows 7 using a SQL Server database on a different server:
TF255440: The following account has a SQL Server login, but the login was denied access: TEST\cameron.fletcher. The server selected to host the databases for Team Foundation Server is: SQL. The SQL Server login associated with the user account must be granted access to the SQL Server instance on that server.
It turns out that although I have a login specifically assigned to me on the SQL box because I am also a member of a SQL administrators group there appears to be some issue with the TFS logic when verifying the connection. The solution? I simply deleted the login and it worked for me.
I have recently been involved in some work that requires me to program on a Remote Desktop (via RDP over an SSL connection) so there is no development software installed locally. One of the downsides is that due to the restricted nature of the connection only text based copy and paste works, so it is not possible to transfer files onto the development environment. Not only this, but although the local machine has access to the internet, the development environment has none.
The solution? I wrote a console based application called MemCopy to copy files to and from the clipboard as text. It does this by either encoding the file as Base64 then saving it as text on the clipboard, or decoding it from the clipboard.
I'd only written this in one of the environments, so I had to decode it in the other before I could use it - a bit chicken and egg, if you ask me. Anyway, I have attached a link to the encoded text here (you didn't think I was going to give you the solution on a plate did you?)
The code below is all that was required to decode it. I placed the encoding into the resources as a file.
byte[] buffer = Convert.FromBase64String(Resources.Encoding);
FileStream stream = new FileStream("memcopy.zip", FileMode.Create,FileAccess.ReadWrite);
BinaryWriter writer = new BinaryWriter(stream);
writer.Write(buffer);
writer.Close();
For those of you without the technical acumen to decode the above source, I have attached a working copy MemCopy as a zip file here. Simply download and extract MemCopy to a folder of your choosing, copy the contents of the encoded text (above) into memory, then execute MemCopy from the extracted location using the following command:
MemCopy /decode MemCopy.zip
The result? Awesomeness.

Occasionally I have received the following error when trying to send emails to other organisation from Exchange 2007:
Diagnostic information for administrators:
Generating server: exchange-server.internal.domain.com
enduser@externaldomain.com
external.mail.server.domain.com #500 Firewall Error ##
It turns out that this is actually due to the Cisco router inspecting SMTP traffic. Entering the command below into IOS fixed the issue:
no ip inspect name SDM_LOW esmtp
I am finding it increasingly hard to illustrate my technical skills on my CV due to the large amount of software I have had exposure to – and I don’t mean just sat next to. So I have created my own technical skills datasheet to accompany my CV a copy of which can be found here.
Evidently, you'll notice that my technical prowess do not extend to creation of well formatted PDF files, as upon resizing or come to print the document the font sizing, spacing, and subsequent readability goes haywire. I blame Adobe.
Andy Aitken, a guy I work with, evidently abused his copy of Visual Studio 2008 to breaking point and got this message in return. Hats off.
UPDATE: It turns out that a week later I too rose to the dizzy heights of Aitken's abuse:
Below is the SQL statement including the common table expression that I need to re-write using Linq2Sql for an application I’m working on. The query identifies the subset of most up-to-date records using a group by query in a CTE. It then performs a join back to the booking table to return the full list of most up-to-date records.What is noticeable about this particular piece of code is the join between table and CTE making use of the isnull keyword.
with cte (RootBookingID, CreatedTime)
as
(
select
isnull(ParentBookingID, BookingID),
max(CreatedTime) -- get the latset version
from [system].Booking
where Deleted = 0
group by isnull(ParentBookingID, BookingID)
)
select b.*
from [system].Booking b inner join cte
on cte.RootBookingID = isnull(b.ParentBookingID, b.BookingID)
and cte.CreatedTime = b.CreatedTime;
When rewriting this in C#, we first declare the query for the CTE as its own variable.
//define the cte to use as an anchor
var cte = from b in this.Model.Bookings
where b.Deleted == false
group b by b.ParentBookingID ?? b.ID into g
select new
{
BookingID = g.Key,
CreatedTime = g.Max(b => b.CreatedTime)
};
We can then reuse this variable within our core query (below). Notice how the join on isnull is created by explicitly defining the name of the anonymous type.
//perform a join on the cte to get the results
var qry = from b in this.Model.Bookings
join c in cte
on new
{
ID = (b.ParentBookingID ?? b.ID),
b.CreatedTime
} equals new
{
ID = c.BookingID,
c.CreatedTime
}
order by b.PickUpTime
select b;
The post here explains the stumbling blocks I encountered:
To join multi-valued keys you need to construct an anonymous type on both sides of the 'equals' that is the same type. The anonymous type initializer expression infers both type and name of members from the expressions that are supplied. Using the name = value syntax in the initializer you can specify the name the compiler uses when creating the type. If all members, types, and names are the same then the anonymous types are the same type.
I bought got my brother to buy some flip-flops at the weekend. Check them out:
And guess what is located on the sole of the them? That’s right, a bottle opener. One per flip-flop:
Now I just need a beer. And a holiday…
Possibly the funniest technical question I've seen posted on a technical message board. Ever. Worth a look and you're guaranteed a laugh.
