The Stack Overflow question “Can I set a private property via reflection?” was answered “Yes, it is” with some good examples on how to set private fields and properties through reflection.

Everytime I get a warning like
Warning 1 'System.Configuration.ConfigurationSettings.AppSettings' is obsolete: 'This method is obsolete, it has been replaced by ConfigurationManager.AppSettings'
it reminds me I should have written a blog post about it, as the solution is a tiny bit more than just replacing System.Configuration.ConfigurationSettings.AppSettings by System.Configuration.ConfigurationManager.AppSettings.
Scott Gate wrote a nice post on his old blog about this (his new blog is awesome, he really should import his old posts into his new blog) that explains how to solve this well, so below is an elaboration on the how of the change, a tiny trick and a short series of steps to resolve this warning.
First of all, the above message means you are touching code that has been written in the .NET 1.x era, and the maintaining people (you! <g>) have been too lazy to solve the warning. That is bad, as your code should compile without warnings, and preferably without hints too. Read the rest of this entry »

If you followed my blog, you probably already guessed that I’m assisting a client to prepare for a big SQL Server 2000 to SQL Server 2008 R2 migration. When not, you know now :)
I’m a fan of commandline, tools, and preconfigured settings. Which means that I’m in the midst of reconfiguring all my shortcuts to SQL Server 2000 tools to SQL Server 2008 equivalents.
When inspecting and changing LNK shortcut files, two tools are important:
One of tools I many shortcuts for is the ISQLW aka SQL Query Analyzer, which I use far more than the SQL Server Enterprise Manager (more on SSEM in a future post).
Depending on the mode of authentication you use to connect to your SQL Server, there basically are two forms of shortcuts:
"C:\Program Files\Microsoft SQL Server\80\Tools\Binn\isqlw.exe" /S"servername[\instancename]" /U"username" /P"password""C:\Program Files\Microsoft SQL Server\80\Tools\Binn\isqlw.exe" /S"servername[\instancename]" /EThe former is less secure (so better to only store those shortcuts in a place that no other users can access).
From the ISQLW.exe syntax documentation:
Syntax
isqlw
[-?] |
[
[-S server_name[\instance_name]]
[-d database]
[-E] [-U user] [-P password]
[{-i input_file} {-o output_file} [-F {U|A|O}]]
[-f file_list]
[-C configuration_file]
[-D scripts_directory]
[-T template_directory]
]
The parameters /S, /U, /P and /E are very similar to the -S, -U, -P and -E ones from SSMS.exe (SQL Server Management Studio) with one distinction: there MUST be a space between each parameter and the value:
"C:\Program Files\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE\Ssms.exe" -S "servername[instancename]" -U "username" -P "password""C:\Program Files\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE\Ssms.exe" -S "servername[instancename]" -EPosted in Batch-Files, Database Development, Development, Power User, Scripting, Software Development, SQL Server, SQL Server 2000, SQL Server 2005, SQL Server 2008, SQL Server 2008 R2, SQL Server 2012 | 5 Comments »

Don’t post screen shots as low quality JPEG.
Use PNG, which results in smaller files and better looking images.
Not like ING did: no screen reader can help visually impaired, and it gives a very bad user experience to the rest of the world.

Something I might want to try soon:
Migrate mailboxes between Microsoft Exchange, Office 365, Novell GroupWise, Google Apps/Gmail, VMWare Zimbra, IMAP or POP systems.
Thanks Scott for mentioning this.

I’m experimenting with the Posting categories overview page as a prequel to a proper tag cloud (and a series of posts on how to get there).
Please let me know in the comments which of the below ones you like most:
(For comparison, you need a big screen; the most popular choice will survive on the Posting categories page).

Recently I was at a site where the KB2509553 security update on Windows XP would not install because of this error, even after retrying a couple of times:
---------------------------
KB2509553 Setup Error
---------------------------
Setup cannot update your Windows XP files because the languageinstalled on your system is different from the update language.
---------------------------
OK
---------------------------
The error came from the Dutch version of Microsoft Update and the (also Dutch) Autoupdate inside Windows XP.
The solution that seemed easy didn’t work:
Manually download the Dutch version at the KB2509553 download page, and install that one.
Thanks Halima S for mentioning this on the Microsoft Answers site.
So: where should I start looking to get this security update installed?

Coo, I never knew that MS-DOS had STDAUX and STDPRN, I only knew about PRN (I think it mapped to LPT1).
Don’t you love the old new thing :)
The standard MS-DOS file handles are as follows:
handle name meaning 0 stdin standard input 1 stdout standard output 2 stderr standard error 3 stdaux standard auxiliary (serial port) 4 stdprn standard printer

a BNF grammer for C# v2 has moved from www.devincook.com/GOLDParser/grammars/index.htm to goldparser.org/grammars.
It is mostly complete, and a good learning experience to both BNF and the C# syntax.
ANTLR grammers are available for C# 2, and a partially for C# 4.

Lot’s of corporate environments keep killing the productivity of their software developers by running WorkPace. They claim to prevent RSI, but the main thing they do is getting you out of your mental flow.
Workpace (yes, it is written in Delphi) hooks itself into processes by injecting REC300.DLL into it.
That particular DLL prevents Delphi XE2 from installing in several of the systems colleagues tried, and gives you error messages like these:
'' is not a valid integer value
Followed by a bunch of access violations, and Process Monitor indicating issues reading the key HKLM\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\REC300.DLL which is part of WorkPace 3.0 (an old 2007 version).
The next problem was Digital Guardian (an old 2010 version) hooking itself into all processes. Uninstalling that is a pain, as it requires a special uninstall key, but luckily the automated update script on the SCCM server’s distribution share contained that in an encrypted form. Uninstalling this solved the problem.
Maybe newer versions of WorkPace and Digital Guardian wouldn’t have interfered with the Delphi XE2 install. If so, that would be another example of technical debt.
WorkPace and Digitual Guardian are most likely there because of government induced regulations in the corporate environment.
I’m feeling a bit like Dilbert now: the corporate environment is interesting, but often they make “getting work done” so much harder than it could be.
