Deploying Asp.Net to a different time zone, Temporal Future Shock! Specified argument was out of the range of valid values. Parameter name: utcDate

by Jon 17. December 2010 09:57

You would have never of thought it but if you compile ASP.NET in a different timezone you could cause yourself some temporal problems.  I recently discovered that parts of ASP.NET are date specific and if you compile an ASP.NET application in one timezone (The UK), and deploy to another timezone (California) you may find that your web application won’t work correctly until the time catches up.  Its all to do with the date stamp in the assemblies, when you install your application onto a server in california the timestamps on the assembly files may be in the future and parts of the ASP.NET framework will refuse to load them.  Just by waiting 8 hours for time to catch up the problem will resolve itself!  Its defiantly worth saying this doesn’t effect all server setups I had no problems with a customer running server 2008 in a different timezone, I only came across this problem with an AJAX enabled system when a customer was running server 2003, but I haven’t had time to test different scenarios

I installed the application the AJAX was ‘working’ however nothing was styling correctly

I viewed the source of the page and started debugging by copying the WebResource.xsd url into different tab, I was surprised to see the following error:

Server Error in '/' Application.

Specified argument was out of the range of valid values.
Parameter name: utcDate

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Parameter name: utcDate
Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

I returned to the system after 8 hours and the site was working and the error was gone! Be careful out there, this was a fully patched server 2003!

2GB Memory Upgrade on a Acer Aspire One 1.83Ghz (533-23Dkk) from 1GB

by Jon 6. November 2010 16:55

This turned out to be trickier than I expected due to a stubborn keyboard, but upgrading my netbook to 2GB of memory has given me a pretty big performance boost so it was well worth doing.  One important point is do not touch the screws on the back of the notebook, the first step is to remove the keyboard and wont need to go anywhere near a Phillips screwdriver until you have removed the keyboard.

What you need:

  1. 2GB laptop memory chip, I used Kingston Memory 2GB PC3-8500 CL7 204 – Pin SODIMM, I got mine from aria.co.uk for £27.99 which seemed like a good/cheap price
  2. A small flat screwdriver to prise off the keyboard
  3. A small Philips screwdriver to remove the screws under the keyboard
  4. Optional - Anti Static wrist strap

The Tools you need - Anti Static wrist strap is optional

1. Open the lid and prise off the Keyboard with a flat screwdriver.  This is actually quite tricky, the keyboard has three clips which you need to press in.  When all the three clips which are coloured in red on the picture below are pressed in you can raise the edge of the keyboard past the clips.  Once you have raised the edge of the keyboard you will feel some resistance from three additional bumps that hold the keyboard in place.  The bumps are coloured in blue in the photo in below.  You need to slightly bend the keyboard on itself to force it past these three bumps.  When you have done this the keyboard will be free and will pivot around the base.

The holding clips, and bumps

2. Once you have removed the keyboard you will see 7 holding screws, remove these screws with a small Philips screwdriver.

Remove the 7 screws

3. When you have removed the screws, place the screwdriver in the small hole on the right to force the back cover off the notebook, turn the notebook over and prise the back cover off.

Push here, to push the backcover off

Prise off the back cover

4. Replace the memory with the new chip, the turn the netbook over and turn it on to confirm it is working correctly.

Swap out the 1GB chip with a 2GB chip

It boots, and shows 2GB

5. Turn the notebook off, put the back cover back on, screw in the 7 screws back in, clip the keyboard in and that’s it, sorted.  You can use the same steps if you want to swap out the HDD for a SSD.

So you want to partially rename loads of files, keep the names intact, and you just want to use a batch file

by Jon 12. October 2010 14:36

So you have a load of files containing the same word which all need to be replaced with another word.  You could buy some software or just use this batch file:

Create a Batch File Called Replace.bat in the folder containing the files you want to rename

@echo off

setlocal

set /p Srch=Text in filename to find:

set /p Repl=Text to replace "%Srch%" with:

echo Searching for filenames containing "%Srch%" and replacing with "%Repl%" ...

for /f "tokens=*" %%a in ('dir /b *%Srch%*') do call :Replace "%%a"      

goto :EOF

:Replace

set x=%1

call set x=%%x:%Srch%=%Repl%%%

ren %1 %x%

Double Click on the Batch File Enter the File Text you want to replace, and the new text

Rename with a Batch Script

And the files are renamed as you expect

Rename Complete

It feels a little old school but hey it works on all pcs without needing to install anything and thats exactly what you need in situations where you need to rename lots of files at the same time
