I just encountered a problem upgrading a client’s website from ASP.NET MVC2 to the preview of MVC3:
Compiler Error Message: CS1061: ‘object’ does not contain a definition for ‘StartDate’ and no extension method ‘StartDate’ accepting a first argument of type ‘object’ could be found (are you missing a using directive or an assembly reference?)
This error happens at runtime when I go to view a particular View in the browser. The view’s Model property was not being typed as my custom type and instead was reverting to the default type of System.Object.
Turns out it’s a known bug that is caused by the fact that the particular view’s .aspx page also has a
<% Import %> directive after the
<% Page %> directive.
The workaround (until the next preview is released) is to swap the two lines around, so that the
<% Page %> is the last directive in the file. eg.
<%@ Import Namespace="Client.Models" %>
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Client.Models.CustomViewModel>" %>
I was looking for a book on learning about Excel pivot tables to give as a gift recently (makes a change from chocolates or a gift voucher – I know!) I found Pivot Table Data Crunching For Microsoft Office Excel 2007 on Amazon for
$AU37.14 (25.93 + 11.21P&P).
Figuring it would be quicker to get it from a real bookshop, I dropped into the Adelaide Borders bookshop, but they didn't have it on the shelf
I then tried the Borders website
- their online price for the same book is just $AU35.95, and they also happen to have an online price guarantee that they'll beat Amazon's standard price + shipping (not required in this case).
It would have been interesting to compare Borders online price to in-store price to see if they were the same. In any case, I ordered from them so we'll see how quickly they deliver.
This all does make me wonder with the advent of Kindle
eBook readers and downloadable movies what the future is for traditional book shops and video rental stores. Not particularly bright I suspect.
BenMc suggested I have a look at The Book Depository. They have the same book for $AU25.33 with free shipping. Might try them next time!
I purchased an Antec TruePower 550 power supply today, but unfortunately that didn't solve the BSOD issue, so it looks like I'll be rebuilding the computer completely. As I've already got a decent server for more serious computing tasks, my aim is to do this as economically as I can. I've come up with the following list:
|CPU ||AMD Athlon II x4 635 |
|RAM ||4Gb DDR3 |
|Motherboard ||ASUS M4A78LT-M LE |
I'll need to add a video card, as my two existing monitors only have VGA input (eg. the motherboard's DVI-D won't be suitable).
I thought it was high time I wrote about how much I'm enjoying being part of LobsterPot Solutions. Since joining Rob and Ben about 6 months ago, I've had the opportunity to work with a range of clients on an interesting selection of problems utilising technologies such as:
- SQL Server
- SQL Analysis Services
- SQL Data Mining
- SQL Server Integration Services
- SQL Reporting Services
- Pivot Viewer
- ASP.NET MVC
- .NET 4.0
I think it's fair to say SQL Server and Business Intelligence (BI) are LobsterPot's bread and butter (or should that be seafood bisque?!), but I also really appreciate the variety of tasks I've worked on. To complete the 3 course meal (following the food theme!), the company continues to hire talented staff. Roger (Mr SharePoint) Noble joined us in May and I'm sure he won't be the last as demand for BI expertise increases.
Another thing that I like is LobsterPot's commitment to staff professional development – from in-house training and conference attendance to user group participation.
Now I'm looking forward to seeing what the next 6 months bring!
Upon returning from TechEd, I went to power up my trusty old workstation (an aging Intel D865PERL-based machine), however it didn't start up at all. After double-checking that it was actually plugged in properly I suspected that the power supply may be the culprit.
I'd had a similar problem with the kid's PC a while back. I'd bought a new replacement SHAW PSU and it worked for a time, but had subsequently started freezing for no reason, so it had been put aside.
I took the new PSU out of that PC and dropped it into my workstation. Turning on the power got an immediate response – fans whirring and all the right sounds coming from the machine. Everything looked good until the after the "Starting Windows" screen disappeared. After a long pause I was greeted by nasty BSOD:
STOP 0x00000116 (0x876c5008, 0x90835640, 0x00000000, 0x00000002)
I could boot the system in Safe mode, but as soon as I allowed it to reboot normally it would BSOD again. Windows 7 Action Center tries to be helpful and suggest I go to the NVidia website to download a new driver that fixes the problem. A nice idea except that the GeForce FX-based graphics card that this machine uses was last supported by driver version 96.85 from 17th October 2006 (which I was already using).
Researching this error I came across this thread. I tried the suggestion of adding the TdrLevel DWORD value to the registry but unfortunately the BSOD remained.
So the problem is somehow related to the graphics driver. Quite bizarre as I've never had problems like this before. The only thing that changed was the PSU. This made me suspect that maybe the new PSU was also problematic. That might well explain why the kid's PC also froze for no reason too.
So what to do? Buy another (better quality?) PSU in the hope that it will resolve the BSOD, or go the full hog and upgrade this circa 2003 system with something a little more modern.
