Natively booting to a VHD with Windows 7 - 10 Steps to VHD’ness

Cesar de la Torre – BLOG - Windows 7 - Natively Booting from a .VHD file (Virtual PC image)

“Most important thing to keep in mind is that we currently cannot boot from any kind of .VHD.

Actually, I have just managed to boot from a Windows 7 installed on a new .VHD, and I installed it right from the Windows 7 DVD. We can do a similar process with "Windows Server 2008 R2 (beta)" installed on a .VHD file, as well.

If you'd use Virtual PC 2007 to install the Virtual image, the produced .VHD wouldn't work when trying to boot from the .VHD.

A.-  Creating the .VHD file and Windows 7 installation on that .VHD file

1. Boot the machine using the Windows 7 DVD

10. Reboot, and you got it!!!!

B.- Configure boot options

…”

Hardware 2.0 - How-to: Getting started with .VHD files in Windows 7 

“Some of you seem confused about how Windows 7 goes about supporting .VHD files as used by Virtual PC, Windows Server 2008 R2 and Hyper-V. Here’s a quick how-to work with .VHD files in Windows 7.

OK, let’s begin with a Windows 7 beta 1 install. Fire up a Command Prompt and type the following:

…”

This is something I’ve wanted to see since it was mentioned at PDC. There’s just something I find too cool about booting to a VHD. Now if I can configure it in such a way as to have differencing disks (i.e. to have the base OS on the main and then later “new” stuff on the diff’s, making it drop dead easy to revert back to a clean/base OS, or to start a new chain off of that base… etc)

Ora, The Region Alternative

CodePlexOra

“Ora is a Visual Studio 2008 add-in that provides an instant grouped overview of the class, interface or struct you are viewing or editing. Because the members are grouped in the order of your choosing, and the view instantly appears when you click in the code of a class, there is no need to abuse the #region feature. Just keep Ora docked next to the source editor and the equivalent groupings just appear automatically.

orascreenshot

Forget using cumbersome #region statements to group together class members. What if you want to see them grouped a different way? And isn't it a bad idea to repeat the same information twice in source code? What if the region structure doesn't reflect the truth? Regions, like comments, should be used to supply information that can't be recovered automatically by an add-in, such as Ora.

Ora is latin for region, amongst other things.

…”

An interesting Visual Studio add-in for those who looking beyond regions for access/grouping. It’s kind of like the Class Diagram but on steroids * 10. And one of cooler things is that sample code is provided so you can add your own grouping. So you’re not tied to how the author decided to group the methods…

Oh yeah, it works for VB projects too.  ;)

Greg’s “Weight Toss” – This is my one year Fat-iversary

Last year I decided it was time to get serious about managing my weight. I’ve always fought my weight as has my father and his family. I looked to him and them as an example, and excuse. Last year I was tired of excuses. It was time I lead by example and took ownership of my weight. To truly own the problem, for if you don’t own it in your heart, it’s very hard to change it. Last year it was time I finally owned my weight.

On 1/9/2008 my official weight was 266 pounds, total cholesterol 223, LDL 187 and HDL 38 and my pants were 44’s. Yeah, ouch.

With professional advice and guidance, I made an wild and insane seeming at the time weight goal of 200 pounds. My initial daily calorie intake goal was 2200, which we’ve since adjusted downward to my current, self imposed, daily goal of 1,600’ish. On 1/10/2008 I started logging my calorie and fat intake and walking at least 30+ minutes a day, five days a week.

Yesterday at my “official” weigh-in I was 198, total cholesterol 152, LDL 93 and HDL 41 and I’m wearing 35’s. Oh cool is that!

image

One way to think about weight management, is that it’s not weight “loss”. You don’t want to find this weight again, do you? Then it’s not a loss. You’re not losing anything. You are the weight tossing! Tossing it out with the garbage. Just as you don’t want to find that garbage back in your house, you don’t want to “find” that weight again either… Not a loss but a toss.

So how do you toss the weight? First, accept that you are going to make an ongoing life style change. That you don’t need to diet, as diets end, but instead to make a basic and long term change to your eating habits and life style.

Second, I suggest professional advice and guidance. My insurance covered my visits with a licenses dietitian (minus co-pay of course). Yours might too. In any case, GET PROFESSIONAL ADVICE. They are trained to help you, they can provide you tips and guidance you might never find if to try to go it alone. It’s not hard, nor painful and they are there to help you… (Thank you Tami, for all your help and advice! You rock! :)

Third, log what you eat, calories at the very least. You will be amazed at the calorie cost of food you are taking in. Yes, it can be hard to get started, but it’s vital that you do this. If you don’t know what you’re taking in, then it’s hard to know how much you need to burn. Just the very act of logging helps make you aware of what you’re eat. I have a log of everything I ate in the last year (in Excel, cause I’m a geek, with charts, daily summary, etc  ;) that without which I wouldn’t have been able to make the life style change I needed to make.

It’s like not having a gas gauge on your car. Imagine the gas tank could get bigger as needed and we didn’t have a gas gauge. We would fill it all the time and keep it full “just in case”? We’d probably also overfill it, not even realizing we were doing it, wouldn’t we? A food log can be your body’s gas gauge.

If you do nothing else, at least be aware of the calorie cost of your current diet. Don’t “cheat” and don’t skip entries. Just be honest with yourself and look at what you’re eating, in hard numbers. I’m telling you, you’ll be shocked at the cost of that dinner you had last night. Or the lunch, or that snack.

You don’t need an expensive program or some fad diet. You need to know what you’re taking in so you know how much to burn. And if you’re not burning much, say because you’re a programmer and sit on your butt most of the day, then you just need to take in less. Sounds simple, but it will take work. Just as important is a willingness to be honest with yourself and to realize that this is a life style change and that only YOU can do it.

Finally, there’s should be no guilt. If you want some ice cream, then have some. Want a cookie? Have one. Just log it and realize you might now have to do more to burn it off. Don’t punish yourself, don’t deny yourself and don’t starve yourself. Remember, “ongoing eating and life style change”. Drastic behavior is not sustainable.

 

Okay, enough for now.

BTW, my new goal is 180. I’d really like to comfortably wear 34’s, and Large T-Shirts (last year I was wearing XXL’s). How cool would it be to say, “I lost a foot… 44’s to 34’s…”   ;)

Using console GHTMDOC utility to convert HTML/ASPX files into PDF’s

CodeProject - Convert aspx pages to pdf

“…

There have been some articles on converting local files to pdf on this site, but I was looking for a solution to serve dynamic pages directly as PDF. This should be done by using the user's session, eg rendering a user-specific report. 

This article shows a quick and dirty way to accomplish this using ghtmldoc. Ghtmldoc is a GPL licensed program that converts a html file on disk to pdf. I have included a binary version of the program, but feel free to create your own as I'm not sure that it's the latest version. You can find more info on htmldoc at http://www.easysw.com/htmldoc/ (I am not in any way connected to them.)

…”

I guess I’m a serious console app kick…

Anyway I’ve been keeping my eyes open from a good, cheap (free) HTML to PDF conversation utility that I can use from .Net for a feature I want to add to my Blogger Backup utility.

All the good conversion libraries I’ve found have all been commercial, and since my utility is open source/source available (and there’s no way I can justify to me DFO spending the funds), the feature has been stalled.

I don’t know if this is the “one” but it looks worth a try…

Using Tesseract (Open Source OCR from Google) as a tool to learning .Net console application launching and monitoring

Rick Minerich's Development Wonderland - Processes in .NET Part 3 – Interfacing With Simple Console Programs by Example, Tesseract OCR

“Did you know that .NET provides an easy way to interact and control console programs?  In this article I will walk you through this process by creating a wrapper class for Google’s Tesseract OCR application.  At the end of this post, I will provide a complete WinForms-based frontend for Google’s Tesseract OCR Engine

You would think that this is a particularly simple case as Tesseract only needs to be passed in parameters and requires no flow control.  Ideally, we will simply leverage the Process class to control how Tesseract is launched and read from it’s output.  Initially, this is only a small jump from what we learned in Processes in .NET Part 2.  The only real difference here is that instead of using Verbs we are specifying behavior through the ProcessStartInfo’s Arguments property

Unfortunately, while this very simple example will work in many cases, this is not one.  This is because Tesseract.exe secretly launches a separate process and immediately exits.  This makes the WaitForExit() call look like it was successful but, as OCR takes a while, when you try to read from the output file it will either not yet exist or it will be locked for writing by the Tesseract process.

There are many different ways to approach this problem.  In this case an easy method would be to try repeatedly to access Tesseract’s log file using a timeout to ensure our program doesn't lock up. …

Designing a Wrapper Class

Tesseract has a number of quirks which makes it somewhat annoying to deal with, at least when compared with most other command line applications.  It’s important to be on the lookout for these kinds of small quirks when building an interface to an application.  For completeness, I’ll list what I’ve found for Tesseract here along with solutions.

An Asynchronous Wrapper for Easy WinForms Integration

Once you have all of the little quirks of your application covered, the only issue left is that calling your ExtractText method leaves your application locked up for it has returned.  The best way to deal with this is to use an DynamicInvoke on a delegate and managing the update to your console application via a callback.  To make this easy I wrote an asynchronous child class.

…”

There’s a ton of cool lessons in this post, from dealing with Tesseract, to handling unusual command line/console app’s to writing non-blocking WinForm code…

“Query Analyzer” for SimpleDB – Visual Studio 2008 Add-in that makes querying SimpleDB almost too easy?

Mindscape Blog - SimpleDB Management Tools Released

“With the present buzz around cloud computing, it’s proved a timely moment for Amazon’s SimpleDB database service to come out of beta. And since it’s free for low-volume usage there’s been a big uptick of interest in SimpleDB. However, although Amazon provide APIs and libraries for programming against SimpleDB, they don’t provide any off the shelf tools for quickly managing or viewing your SimpleDB data.

We’re therefore pleased to announce the release of SimpleDB Management Tools, a Visual Studio add-in that you can use to manage your Amazon SimpleDB domains and data from within VS2008.

sqlquery

Using SimpleDB Management Tools, you can create and delete domains, view the contents of your domains, run queries and edit and save data, using the kind of visual interface familiar from traditional databases such as SQL Server or MySQL. SimpleDB Management Tools installs itself as a data provider in Server Explorer, from where you can navigate your domains and launch query windows …

There’s a free version of SimpleDB Management Tools available. The free version only allows you to view or edit the first 20 results of a query, but is otherwise fully functional and is not time-restricted. Please note that you’ll need Visual Studio 2008 Standard edition or above. Purchasing a license is inexpensive at only $29 per seat and is available immediately …”

Why too easy? Because now they’ve made me really want to play with SimpleDB! Grrr! It’s not like I don’t have enough “Greg Project’s” already!  LOL

What caught me eye was the interface. There just something about writing SQL statements… Yeah I know, I need help. I also liked the price point. Both that there’s a free (limited) one and that the commercial version is $29. $29 is nice price point for something like this. Not too cheap, yet still affordable for hobbyist dev (or Pro who has to justify this to his DFO, his Domestic Financial Officer… ;)

BTW, if you’re interested in this, then you might want to check out their LightSpeed product. This is their ORM product (for which they are also offering a Free Express version) which has, or will have in the very near future, native support for SimpleDB. Yep, a Cloud enabled ORM… How cool is that?

Thanks to John-Daniel for the heads up.

SQL Server VARBINARY vs FILESTREAM – The code and performance trade offs saving the right sized files to the right datatype.

CodeProject - How to store and fetch binary data into a file stream column

“File streams were introduced in SQL Server 2008. They offer the capability to store binary data to the database but outside the normal database files. Earlier, varbinary used to be stored inside database files, which had many side-effects. Because SQL Server stores data in blocks which are arranged as extents, the data in earlier varbinary columns had to conform to the block structure (although a bit different from normal data blocks).

In SQL Server 2008, if a varbinary column is defined to be stored as a file stream, the binary data is stored in a special folder structure which is managed by the SQL Server engine. The only thing that remains inside the database is a pointer to the file along with a mandatory GUID column in order to use the file stream from the Win32 client.

File stream data can be used from the .NET Framework using the traditional SqlParameter, but there is also a specialized class called SqlFileStream which can be used with .NET Framework 3.5 SP1 or later. This class provides mechanisms, for example, for seeking a specific position from the data.

With a small amount of binary data, it's not efficient to use a file stream. This is because it needs extra overhead like file creation and handling. These operations are not needed when predefined database files are used. However, with larger files, file streams are quite efficient. The following charts show the elapsed times for upload in milliseconds using different techniques, on my development box. The key specifications for the computer used were:

  • SQL Server and client application on the same machine
  • Processor: Intel Core2 Duo, 1.8 MHz
  • 4 GB physical memory
  • Database files on drive C:
  • Files uploaded from drive E:
  • Drives C: and E: on separate physical SATA disk drives

The charts show average upload times for:

  • 100 KB file repeated 3 times for each measurement
  • 1 MB file repeated 3 times for each measurement
  • 10 MB file repeated 3 times for each measurement

…”

What I liked about this article is that not only is the sample a complete soup-to-nuts, SQL Create all the way through to sample code, but it also provides a harness for performance comparison using storage different techniques (as well as data run charts ;).

It makes clear, what is becoming more commonly known, that FILESTREAM is good for larger files and VARBINARY for smaller ones. But of course, YMMV. Also make sure you listen to the Run As Radio show I link to below, Run to Run As Radio for a great SQL Server 2008 FILESTREAM show, for some great FILESTREAM configuration/performance tips.

Two new Lucene.Net Articles, Text Analysis and Custom Synonym Analyzer

CodeProject - Lucene.Net - Text Analysis

“Lucene.Net is a high performance Information Retrieval (IR) library, also known as a search engine library. Lucene.Net contains powerful APIs for creating full text indexes and implementing advanced and precise search technologies into your programs. Some people may confuse Lucene.net with a ready to use application like a web search/crawler, or a file search application, but Lucene.Net is not such an application, it's a framework library. Lucene.Net provides a framework for implementing these difficult technologies yourself. Lucene.Net makes no discriminations on what you can index and search, which gives you a lot more power compared to other full text indexing/searching implications; you can index anything that can be represented as text. There are also ways to get Lucene.Net to index HTML, Office documents, PDF files, and much more.

What are Analyzers?

An Analyzer has a single job, and that is to be a advanced work breaker. Which an object that will read a stream of text and break apart the words into objects called Tokens. The Token class will generally hold the results of the analysis as individual words. This is a very brief summary of what an Analyzer can do and how it affects your full text index. A good Analyzer will not only break the words apart, but it is also performs a transformation of the text to make it more suitable for indexing. One simple transformation an Analyzer can do is to lowercase everything it comes across, that way your index will be case insensitive. 

In the Lucene framework there are two major spots where an Analyzer is used, and that is when indexing and then searching. For the indexing portion, the direct results of the Analyzer is what gets indexed. So for example, in a previous example of an Analyzer that will convert everything to lowercase, if we come across the word "CAT", the analyzer will output "cat", and in the full text index, a Term of "cat" will be associated with the Document. For an even bigger example if we use an Analyzer that will break the words apart with the spaces, and then the Analyzer will convert it all to lowercase the follow the results should look something like this.

Attached to this article is the the Analyzer Viewer application, that I made. Attached are both the source and a ready to run binary of the application.. The sample is more like a little utility to see how the basic Analyzers included with Lucene.Net will view text. The application will allow you to directly input some text, and it will show you all the results of the text analysis, and how it split them up into tokens and what transformations it applied.

Some interesting things to looks at include, typing in email addresses, numbers with letters, numbers alone, acronyms, alternating cases, and just anything else you want to play with to see how the indexing process goes. 

Implementations of a Tokenizer.

As i mentioned earlier the Tokenizer class is an abstract base class of a TokenStream. Lucene.Net provides a few implementations of a Tokenizer that it uses in some of the Analyzers. Here is a couple of them and a small description of each.

KeywordTokenizer - This Tokenizer will read the entire stream of text and return the whole things as a single Token.

…”

CodeProject - Lucene.Net – Custom Synonym Analyzer

“…

How Do I Get Lucene.Net to Work with Synonyms?

The goal here is to be able to search for a word and be able to retrieve results that contain words that have the same meaning as the words you are searching for. This will allow you to be able to kind of search by meaning than search by the keywords.

We can easily get Lucene.Net to work with synonyms by creating a custom Analyzer class. The Analyzer will be able to inject the synonyms into the full text index. For some details on the internals of an Analyzer, please see my previous article Lucene.Net – Text Analysis.

Points of Interest

The SynonymAnalyzer is really great for indexing, but I think it might junk up a Query if you plan to use the SynonymAnalyzer for use with a QueryParser to construct a query. One way around this is to modify the SynonymFilter, and SynonymAnalyzer to have a bool switch to turn the synonym injection on and off. That way you could turn the synonym injection off while you are using it with a QueryParser.

The code attached includes the Analyzer Viewer application that I had in my last article, but it also includes an update to include our brand new synonym analyzer.

..”

 

Two new cool Lucene.net articles from Andrew Smith (blog). I swear that I’m going to use Lucene.Net one of these days… ;)

See behind the SQL Server curtain with the Internals Viewer for SQL Server

Notes from SQL Server Premier Field Engineer - Internals viewer for SQL Server

“…

I am guessing I won't be making big news if I tell you that SQL Server database is just a collection of 8K pages. Each page serves different purpose. There are data pages, which hold actual rows in tables, there are index pages which make up index, SGAM/GAM pages which track extents, PFS pages which track free space on pages in the database, IAM pages, overfow pages and many others... … If all this sounds familiar, let me tell you that there is actually a better way :). Danny Gould developed an awesome tool Internals Viewer for SQL Server which integrates with SQL Server Management Studio and allows you easily drill into individual pages and better understand the relationships between them and overall architecture of SQL Server storage engine.

Give it a serious try and have fun playing and learning internals of Microsoft DBMS !”

CodePlex - Internals Viewer for SQL Server

“Internals Viewer is a tool for looking into the SQL Server storage engine and seeing how data is physically allocated, organised and stored.

All sorts of tasks performed by a DBA or developer can benefit greatly from knowledge of what the storage engine is doing and how it works

Features

  • Integration with SSMS (SQL Server Management Studio) 2005 and 2008
    • The application is installed as a SSMS add-in
    • Internals information integrated into the Object Explorer
    • Transaction Log viewer integrated into the Query Results
  • Allocation Map
    • Displays the physical layout of tables and indexes
    • Displays PFS status
    • Overlay pages in the Buffer Pool
  • Page Viewer
    • Displays Data pages including forwarding records and sparse columns
    • Displays Index pages
    • Displays allocation pages (IAM, GAM, SGAM, DCM, and BCM pages)
    • Displays pages with SQL Server 2008 row and page compression

…”

Sometimes you need to see behind the curtain and into the depths. This utility, for which the C# source is available too, sounds like it is one of those tools that can come in handy during a SQL Server spelunking expedition.

This utility also provides a working example of how to integrate into SQL Server Management Studio, so it’s like a two for one deal ;)

Top Office Templates – Not just business stuff going on…

Office At Work - Most popular templates in 2008

“So we've seen which how-to articles were the most popular this year, but what about templates? I'm a big fan of the free Office Online templates and regularly try to point out some of the hidden gems contained on the website, so I was really interested to see which templates have been downloaded the most over the year...

  1. Fax cover sheet (Professional design)
  2. Technology business brochure (2-pg, 11 x 17)
  3. Memo (professional theme)
  4. PTA agenda
  5. Chronological CV (minimalist theme)

…”

Seeing a PTA Agenda in the Top 5 Office templates downloaded just struck me as funny. And given the year we’ve had, we need some funny in our lives… ;)

Actually I think it’s pretty cool, and the Office Online team should be pretty happy, having a template like that in the top 5. I feel it seems to mean that “normal/causal” consumers are using the Office Online site. The other four can be chalked up to power and business users, but the PTA Agenda… well… (of course the little voice in my head is telling me that it was the business and power users who found and downloaded that template for their partner in parenting because they were tired of having to do it manually or seeing them do it on paper… in any case, it’s a win… ;)

Deadlock avoidance when using redirected StandardInput, StandardOutput and StandardError with System.Diagnostics.Process

Lucian's VBlog - System.Diagnostics.Process: redirect StandardInput, StandardOutput, StandardError

“Sometimes you want to launch an external utility and send input to it and also capture its output. But it's easy to run into deadlock this way...

The deadlock in this case arises because "cat" (a standard unix utility) first reads from StandardInput, then writes to StandardOutput, then reads again, and so on until there's nothing left to read. But if its StandardOutput fills up with no one to read it, then it can't write any more, and blocks.

The MSDN documentation says, "You can use asynchronous read operations to avoid these dependencies and their deadlock potential. Alternately, you can avoid the deadlock condition by creating two threads and reading the output of each stream on a separate thread." So that's what we'll do...

Using threads to redirect without deadlock

' GOOD CODE: this will not deadlock.

Using p As New Diagnostics.Process

    p.StartInfo.FileName = "sort"

    p.StartInfo.UseShellExecute = False

    p.StartInfo.RedirectStandardOutput = True

    p.StartInfo.RedirectStandardInput = True

    p.Start()

    Dim op = ""

    ' do NOT WaitForExit yet since that would introduce deadlocks.

    p.InputAndOutputToEnd("world" & vbCrLf & "hello", op, Nothing)

    p.WaitForExit()

    p.Close()

    Console.WriteLine("OUTPUT:") : Console.WriteLine(op)

End Using

I’ve got a redirect StdIn/StdOut/StdErr related project on the books and this tip might come in handy

A little VSTS VPC download help – Steve lists all 10 parts for easier FDM’ing

How Steve Got Burned Today - TFS and VSTS 2008 "All-up" Hyper-V Image Links for Free Download Manager

“Here are the download links for the Hyper-V version of the new TFS/VSTS 2008 "all-up" virtual machines that I posted about last week.  I'm mostly putting these here so that I can find them, but I think others may find them useful as well.

These links are compatible with the Free Download Manager tool.  Just copy them to the clipboard then open FDM and select File | Import | Import list of URLs from clipboard or just use the Ctrl + Shift + V hotkey.

…”

Steve provides a simple list of the new Hyper-V VSTS VHD links, making it much easer to download all 10 parts of the RAR via a download utility like FDM.

File and Directory Path help from the man who brought us NDepend

CodePlex - NDepend.Helpers.FileDirectoryPath

“NDepend.Helpers.FilePathDirectory is the library used by the tool NDepend to handle common path operations. Benefits of the NDepend.Helpers.FilePathDirectory over the .NET Framework class System.IO.Path include:

  • Strongly typed File/Directory path.
  • Relative / absolute path conversion.
  • Path normalization API
  • Path validity check API
  • Path comparison API
  • Path browsing API.
  • Path rebasing API
  • List of path operations (TryGetCommonRootDirectory, GetListOfUniqueDirsAndUniqueFileNames, list equality…)

NDepend.Helpers.FilePathDirectory is 100% unit-tested and tests code is provided with the source code.

…”

There are some features here that we reinvented recently ourselves, plus tons I really like the sound of (plus I dig that the unit tests are already there ;)… Next update to that project I’m going to have to see if we can use this instead. We’ll have to get approval from “on high” since this is a LGPL licensed project, but that should pose too much of a hindrance…
