In the .NET 1.x past, the WinForms designers in Visual Studio .NET and Visual Studio 2003 would put the C# or VB.NET code containing the form code as the InitializeComponent method of the top most class monolithic C# and VB.NET files that also contain the user code (for events and such).
As of Visual Studio 2005 (actually: Whidbey and higher), this code is based on partial classes. For each form (actually designable entity, but lets limit this to WinForms forms) you get a MyForm.cs and MyForm.Designer.cs
As a side note, with a bit of effort, you can generate the Windows Form Designer generated code yourself as this answer shows. This is for instance convenient when you have form definitions in a different technology and want to convert it to WinForms, WPF or another form of designer based .NET code.
I long time ago I wrote a short manual for co-workers on converting the monolithic files (for people interested, it is below).
Since then I found a couple of very interesting links: Read the rest of this entry »

Until I realized that comparing two IEnumerables needed some extra thought, I wondered why Assert.AreEqual would not support them.
jrista pointed me in the right direction answering a question about c# – How does Assert.AreEqual determine equality between two generic IEnumerables?
The correct answer is “it doesn’t”, but that is really dense.
IEnumerables are just that: being generic or normal, they allow you to enumerate things. They can get you an enumerator (generic or not) that has a notion of Current (generic or normal) and such, but no knowledge of the underlying data.
Comparing them needs you to think about the enumeration and the underlying data at the same time. You can get two kinds of comparisons: Read the rest of this entry »

When developing in multiple languages, it sometimes is funny to see how they differ in compiler oddities.
Below are a few on const examples.
Basically, in C# you cannot go from a char const to a string const, and chars are a special kind of int.
In Delphi you cannot go from a string to a char. Read the rest of this entry »

Sometimes the Java Update checker crashes in the middle of something.
The long solution to restart it is to logoff/logon or reboot/logon and wait for it to come up.
The short solution is to manually restart it (you probably need to be Administrator to do this though) using either of these commands:
"%CommonProgramFiles%\Java\jucheck.exe" -auto
"%CommonProgramFiles%\Java\Java Update\jucheck.exe" -auto
"%CommonProgramFiles(x86)%\Java\jucheck.exe" -auto
"%CommonProgramFiles(x86)%\Java\Java Update\jucheck.exe" -auto
To keep it simple: The exact command depends (:
- if you run on an x86 machine or not, or – on an x64 machine – which of the Java versions (x86 or x64) you have installed
- if the
jucheck.exe is in the Java directory itself, or in a Java Update directory

You’d hope that a method like Wordify with the signature below would be simple right?
public static string Wordify(string pascalCaseString)
Not so. Read the rest of this entry »

On development machines it can be comfortable to add the local Administrators group to SQL Server, and make them equivalent to SA (SQL Server Administrator).
This especially as SA is disabled by default when you install using Windows Authentication mode (which is the default). You can Change Server Authentication Mode to include SQL Server mode, but then you still have to enable SA (you can even rename SA)
This is basically what you want to do:
CREATE LOGIN [BUILTIN\Administrators] FROM WINDOWS WITH DEFAULT_DATABASE=[master];
EXEC master..sp_addsrvrolemember @loginame = N'BUILTIN\Administrators', @rolename = N'sysadmin';
GRANT CONTROL SERVER TO [BUILTIN\Administrators];
There are a few gotchas here:
- The name of the group BUILTIN\Administrators depends on the localization of your system.
This is one of the reasons I usually advise clients to have server systems run on the most common ENU (English USA) localization of Windows.
Another reason is that it is far easier to find information ENU English Messages back on the internet.
- You need to be SQL Server Administrator to begin with.
There is a little trick to get this done: you can stop the SQL Server service, then restart SQL Server it in single-user mode.
In single-user mode, members from the BUILTIN\Administrators group can connect as a member of the sysadmin fixed server role.
- If you want to access SQL Server as member from BUILTIN\Administrators, you need to run your SQL client tools with the UAC elevated permission (otherwise the Administrative bit is not set, and the BUILTIN\Administrators is not recognized).
That’s what the batch file below solves.
You need to start it as member of BUILTIN\Administrators with elevated privilege (the easiest way is to run it from an elevated command prompt).
It will: Read the rest of this entry »

Every time I use regular expressions (or post about them), it makes me think about the classic RegEx post by Jeff Atwood: to compile or not to compile.
BTW: Happy 2013!

A lot of scripts you find on the internet have hardcoded Windows account names or groups, for instance BUILTIN\Administrators
Those don’t work on many localized Windows versions, as part of the account names have been translated as well. Not only Administrators is translated, but BUILTIN can be translated too. Basically, expect everything in Windows to be translated as part of the localization process.
Some people keep translations lists, but that is not the real solution.
The real solution is that each such group, account or other identifier stems from a SID or Security ID.
Many of those SIDs are the same on any machine, or structured the same within a domain.
Microsoft has a list of these called Well-known security identifiers in Windows operating systems.
That list isn’t in a format most Windows tools use it, so I generated the list below that is more suitable.
The list below is based on a Windows 7 machine. Other versions or editions give slightly different results, but it is a good start.
At the bottom is the batch file that I used to generate this table. That file is adapted from the Microsoft list above.
The batch file depends on a few tools and tricks: Read the rest of this entry »

There is a lot of information in Assembly that is either internal or private. Luckily you van get an AssemblyName instance through Assembly.GetName() or Assembly.GetName(Boolean) which has quite a few public members that get initialized while calling the internal AssemblyName.Init method.
This is the member mapping of AssemblyName members to Assembly members:
