How To Backup Bootable USB Drive

Posted by jpluimers on 2012/10/15

I needed to make backups of a couple of maintenance USB drives.

It turned out to be pretty easy: How To Backup Bootable USB Drive describes how to do that based on a small USB Image Tool developed in .NET.

One of the things you can do with this is backup bootable Windows installation media.

Note it is a simple tool, so it backups only same size to same size. For more advanced copy purposes, use something like the professional tools from Acronis.

Elfproef as T-SQL UDF

Posted by jpluimers on 2012/10/09

As a follow-up on my earlier number validation posts (Elf proef in C# and Other number verifications), I found a nice T-SQL version of the Elfproef for Dutch bank account numbers.

It works at least from SQL Server 2000 and up, most likely also in the (unsupported) SQL Server 7.

Some notes on multi-touch and Windows

Posted by jpluimers on 2012/10/06

While fooling around with Microsoft Surface, you are astonished with the number of fingers it supports: 10 is no problem on the Samsung SUR40 which can also do full HD resolution (more specs here).

Not so with the standard Windows 7 touch support: that has only 2.

As I want to increase that to better mimic the development environment to the actual environment a few notes:

asp.net – Should the WebInfo file be excluded from SVN – Stack Overflow

Posted by jpluimers on 2012/10/03

When moving a truckload of stuff from Visual Source Crash, I came a long many .webinfo files.

I wasn’t sure they should be in TFS, and indeed they should not:

.webinfo should be excluded. (Some info about webinfo: How to copy and configure ASP.NET projects between different local computers)

Portable Library Tools extension: hopefully a Visual Studio 11 studio comes soon

Posted by jpluimers on 2012/10/02

Portable Library Tools extension is a great tool for creating assemblies that run on a variety of .NET platforms without recompilation.

I hope a Visual Studio 11 version of it comes soon.

YinYang Zend Framework Supplement Library

YinYang is a library of classes. Generally anything that is created in addition to Zend Framework and can be reused will be included in this library. YinYang requires Zend Framework as most of the classes extend ZF.

To use, simply checkout a copy, add the library/YinYang folder to your library folder and add YinYang to your list of autoloader namespaces.

Please fellow programmers, name variables more properly.

The code I had a hard time understanding

The below code didn’t compile during a .NET 1.1 to 4 migration.

Downstream code:

Word.Document document = app.Documents.Add(ref FileName, ref missing, ref missing, ref missing);

Upstream code (6 layers up!):

string filename = Path.Combine(ConfigurationSettings.AppSettings["MSWordTemplateDirectory"], (string)status["CoverLetter"]);

And somewhere in the middle:

public bool GenerateLetter(Word.Application app, DataRow row, object FileName, object FilePathAndName)

Afterwards the code is this

Downstream code:

Word.Document document = app.Documents.Add(ref templateFileName, ref missing);

Upstream code (6 layers up!):

templateFileName = Path.Combine(ConfigurationSettings.AppSettings["MSWordTemplateDirectory"], (string)status["CoverLetter"]);

And somewhere in the middle:

public bool GenerateLetter(Word.Application app, DataRow row, object templateFileName, object documentFileName)

Coincidentally, parameters are now all lowercase.
