  • Chrome OS is missing or damaged

    - by Ken
    My Google Chrome CR-48 started flaking out/rebooting and finally this message.  This post solved the problem quite easily. http://cr-48.wikispaces.com/Reseat+SSD+Cable Two hints: 1) you need to pull off the rubber feet to get at some screws. 2) the real problem is the little white clip under the cable.  Don’t worry about reseating anything, Just push the cable back on and the little white clip back up to snap in place and hold the cable.

  • Microsoft Certifications &ndash; how to prep? and why?

    - by Kelly Jones
    I often get asked by my colleagues, “how do you prepare for Microsoft exams?” Well, the answer for me is a little complicated, so I thought I’d write up here what I do. The first thing I do is go to Microsoft’s website to find the exam that I need to take.  If you’re looking to get a particular certification, then their site lists the exam or exams that you’ll need to pass.  If you’ve already taken an exam, you can log onto the MCP website and use their certification planner.  This little tool tells you what tests you need, based on the exams you’ve already passed.  It is very helpful with the certifications that are multiple tests and especially ones that have electives. Once you’ve identified the test, you can use Microsoft’s website to see the topics that it covers.  This is a good outline to follow when you study.  I’ll keep this handy to reference back throughout my studying to make sure that I’m covering all the topics I need to know. The next step is probably where I am a little different from others.  IF the exam outline covers material that I’ve already been working with, then I’ll skip a lot of the studying and go directly to the practice tests.  However, if I’m looking at the outline and wondering how in the world do you do that? – then it’s time to hit the books. So, where to find study materials?  Try typing in the exam number into any search engine.  You’ll typically find a ton of resources.  If you’re lucky, you’ll find books that others recommend based on their studying and exam experience.  As a Sogeti employee, I have access to three really good resources: an internal company list of all of the consultants who have passed particular tests (on our Connex website), Books 24x7, and Transcender practice exams. Once my studying is done (either through books or experience), I’ll go through the practice exams.  I find them really helpful in getting my knowledge lined up to the thinking process that the exam writers use.  If I’m relying on my experience, then this really helps me to identify gaps in my knowledge that I’ll need to fill. That’s about it.  If I’m doing ok on the practice exams, then I’ll take the real thing.  I’ve found that the practice exams are usually more difficult than then real thing. Oh – one other thing I do related to Microsoft exams – I try to take any beta exams that Microsoft makes available that fall into my skill set.  Microsoft has started a blog to announce these and the seats usually fill up really quick.  The blog is at http://blogs.technet.com/betaexams/ . You don’t get your results instantly, like a normal exam, instead you have to wait for everyone to finish taking the beta exams and for Microsoft to determine which questions they are using and which they are dropping.  So, be prepared to wait six to eight weeks for your results.

  • Getting a virus is *very* annoying

    - by bconlon
    I spent most of yesterday removing an annoying virus from my PC. I feel slightly foolish for getting one in the first place, but after so many years I guess I was always going to eventually succumb. I was also a little surprised at the failure of various tools at removing it. The virus would redirect the browser to websites including ‘licosearch’, ‘hugosearch’ and ‘facebook’, and the disk would be thrashing away infecting dlls in some way. I had the full up to date version of McAfee installed. This identified that there was an issue in some dlls on the system and was able to ‘fix’ them. But they kept getting re-infected. So I installed Microsoft Security Essentials and this too was able to identify and ‘fix’ the infected dlls. The system scans take forever and I really expected better results. I also tried Malwarebytes, Hitman Pro, AVG and Sophos to no avail. Eventually I thought I’d investigate myself. It turned out that on reboot, the virus would start 3 instances of Firefox.exe which I’m guessing would do bad things including infecting as many dlls on the system as possible. I removed Firefox and the virus cleverly then launched 3 instances of Chrome! So I uninstalled Chrome and yes, it then started to launch 3 instances of iexplore.exe. If I’m honest, by this stage I was just seeing if it would be able to use any of the browsers! As it was starting these on reboot, I looked in my User Startup folder and there was a <randomly named>.exe and several log files. I deleted these and rebooted. When I looked they had been recreated. So I then looked in the registry Run and RunOnce entries: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. Sure enough there were entries to run a file in C:\Program Files\<random name folder>\<random name file>.exe. I deleted this and rebooted and it was fixed. I also looked in the event log and found a warning that Winlogon had failed to start the file C:\Program Files\<random name folder>\<random name file>.exe So I also checked HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon and this entry had also been changed. Finally I ran a full system scan to clean up any infected dlls. I hope it’s gone for good!  #

  • BizTalk: Using context for routing

    - by Leonid Ganeline
    [See Sample: Context routing and throttling with orchestration] Imagine the project where most of the routing happens between orchestrations. I.e. routing is mostly between the MessageBox and orchestration with direct endpoints. Imagine also the most of the messages are with the same Message type. Usually in this case messages got the special node only for the routing. For example, the field can be the “Originator” or “Recipient” or “From” or “To”. What wrong is with this approach, it creates the dependency between the message and the message processing. Message “knows” something about Originator or Recipient. So what we can do with it? How can we “colorize” the same message to route it to the different places without changing the message itself? One of the decisions is to use the message context. BizTalk uses the promoted properties for routing.  There are two kinds of the properties: the content properties and the context properties. The content property extracts its value from inside the message, it is a value of the element or attribute. [See MSDN] The context property gets its value from the message environment. It can be the port name that receive this message, it can be the message Id, created by the BizTalk. Context properties look like the headers in the SOAP message. Actually they are not the headers but behave like headers. The context properties are the good match for our case. First, we don’t have to change the message itself to set or change the routing property. The context is stored outside the message body. Second, we don’t have to create the property schema to use the context properties. [See MSDN: How to create Property schema] BizTalk has the predefined schema set for the context properties. [See MSDN: Message Context Properties] Use one of them and that's it. The main purpose of the context properties is working on behalf of the BizTalk internals. But we can read, create and change them. Just do not interfere with BizTalk internals on this way.

If I counted correctly, there are 173(!) videos from this year’s conference, and a total of 467 videos from this and previous years. I’ve watched a lot of sessions from the major conferences that include .NET material, and NDC consistently has the best presentations in my opinion. There are lots of my favorite speakers: Crockford, Uncle Bob, Damian Edwards, Venkat Subramanian, Hanselman (I’m interested in seeing if he still thinks “poop” is funny, or got that out of his system at TechEd ;), Cory House (hey, KC!), the .NET Rocks Guys and more, so check it out!

  • Answers to Conference Revenue Tweet Questions

    - by D'Arcy Lussier
    Originally posted on: http://geekswithblogs.net/dlussier/archive/2014/05/27/156612.aspxI tweeted this the other day… …and I had some people tweet back questioning/asking about the profit number. So here’s how I came to that figure. Total Revenue Let’s talk total revenue first. This conference has a huge list of companies/organizations paying some amount for sponsorship. Platinum ($1500) x 5 = $7500 Gold ($1000) x 3 = $3000 Silver ($500) x 9 = $4500 Bronze ($250) x 13 = $3250 There’s also a title sponsor level but there’s no mention of how much that is…more than $1500 though, so let’s just say $2500. Total Sponsorship Revenue: $20750.00 For registrations, this conference is claiming over 300 attendees. We’ll just calculate at 300 and the discounted “member rate” – $249. Total Registration Revenue: $74700.00 Booth space is also sold for a vendor area, but let’s just leave that out of the calculation. Total Event Revenue: $95450.00 Now that we know how much money we’re playing with, let’s knock out the costs for the event. Total Costs Hard Costs Audio/Visual Services $2000 Conference Rooms (4 Breakouts + Plenary) $2500 Insurance $700 Printing/Signage $1500 Travel/Hotel Rooms $2000 Keynotes $2000 So let’s talk about these hard costs first. First you may be asking about the Audio Visual. Yes those services can be that high, actually higher. But since there’s an A/V company touted as the official A/V provider, I gotta think there’s some discount for being branded as such. Conference rooms are actually an inflated amount of $500 per. Venues make money on the food they sell at events, not on room rentals. The more food, the cheaper the rooms tend to be offered at. Still, for the sake of argument, let’s set the rooms at $500 each knowing that they could be lower. For travel and hotel rooms…it appears that most of the speakers at this conference are local, meaning there’s no travel or hotel cost. But a few of them I wasn’t too sure…so let’s factor in enough to cover two outside speakers (airfare and hotel). There are two keynotes for this event and depending on the event those may be paid gigs. I’m not sure if they are or not, but considering the closing one is a comedian I’m going to add some funds here for that just in case. Total Hard Costs: $10700 Now that the hard costs are out of the way, let’s talk about the food costs. Food Costs The conference is providing a continental breakfast (YEEEESH!), some level of luncheon, and I have to assume coffee breaks in between. Let’s look at those costs. Continental Breakfast $12 per person Lunch Buffet $18 per person Coffee Breaks (2) $6 per person (or $3 a cup) Snacks (2) $10 per person (or $5 each) Note that the lunch buffet assumes a *good* lunch buffet – two entrees, starch, vegetable, salads, and bread. Not sure if there’ll be snacks during coffee breaks but let’s assume so. Total Food Cost Per Person: $46 Food Cost: $14950 Gratuity: $2691 Total Food Cost: $17641 Total food cost is based on the $46 per person cost x 325. 300 for attendance, 12 for speakers, extra 13 for volunteers/organizers. Gratuity is 18%. Grand Totals So let’s sum things up here. Total Costs Hard Costs: $10700.00 Food Costs: $17641.00 Total:          $28341.00 Taxes:         $3685.00 Grand Total  $32026.00 Total Revenue Sponsorship  $20750 Registration   $74700 Grand Total   $95450.00 Total Profit $63424.00 Now what if the registration numbers were lower and they only got 100 people to show up. In that scenario there’d still be a profit of just under $26000. Closing Comments A couple of things to note: - I haven’t factored in anything for prizes. Not sure if any will be given out - We didn’t add in the booth space revenue - We’re assuming speakers aren’t getting paid, but even if they were at the high end its $12000 ($1000 per session), which is probably an inflated number for local speakers. - Note that all registrations were set to the “member” discounted price. The non-member registration price is higher. There is also an option for those that just want to show up for the opening keynote. There you have it! Let me know if you have any questions. D

  • C#&ndash;Using a delegate to raise an event from one class to another

    - by Bill Osuch
    Even though this may be a relatively common task for many people, I’ve had to show it to enough new developers that I figured I’d immortalize it… MSDN says “Events enable a class or object to notify other classes or objects when something of interest occurs. The class that sends (or raises) the event is called the publisher and the classes that receive (or handle) the event are called subscribers.” Any time you add a button to a Windows Form or Web app, you can subscribe to the OnClick event, and you can also create your own event handlers to pass events between classes. Here I’ll show you how to raise an event from a separate class to a console application (or Windows Form). First, create a console app project (you could create a Windows Form, but this is easier for this demo). Add a class file called MyEvent.cs (it doesn’t really need to be a separate file, this is just for clarity) with the following code: public delegate void MyHandler1(object sender, MyEvent e); public class MyEvent : EventArgs {     public string message; } Your event can have whatever public properties you like; here we’re just got a single string. Next, add a class file called WorkerDLL.cs; this will simulate the class that would be doing all the work in the project. Add the following code: class WorkerDLL {     public event MyHandler1 Event1;     public WorkerDLL()     {     }     public void DoWork()     {         FireEvent("From Worker: Step 1");         FireEvent("From Worker: Step 5");         FireEvent("From Worker: Step 10");     }     private void FireEvent(string message)     {         MyEvent e1 = new MyEvent();         e1.message = message;         if (Event1 != null)         {             Event1(this, e1);         }         e1 = null;     } } Notice that the FireEvent method creates an instance of the MyEvent class and passes it to the Event1 handler (which we’ll create in just a second). Finally, add the following code to Program.cs: static void Main(string[] args) {     Program p = new Program(args); } public Program(string[] args) {     Console.WriteLine("From Console: Creating DLL");     WorkerDLL wd = new WorkerDLL();     Console.WriteLine("From Console: Wiring up event handler");     WireEventHandlers(wd);     Console.WriteLine("From Console: Doing the work");     wd.DoWork();     Console.WriteLine("From Console: Done - press any key to finish.");     Console.ReadLine(); } private void WireEventHandlers(WorkerDLL wd) {     MyHandler1 handler = new MyHandler1(OnHandler1);     wd.Event1 += handler; } public void OnHandler1(object sender, MyEvent e) {     Console.WriteLine(e.message); } The OnHandler1 method is called any time the event handler “hears” an event matching the specified signature – you could have it log to a file, write to a database, etc. Run the app in debug mode and you should see output like this: You can distinctly see which lines were written by the console application itself (Program.cs) and which were written by the worker class (WorkerDLL.cs).

  • filtering dates in a data view webpart when using webservices datasource

    - by Patrick Olurotimi Ige
    I was working on a data view web part recently and i had  to filter the data based on dates.Since the data source was web services i couldn't use  the Offset which i blogged about earlier.When using web services to pull data in sharepoint designer you would have to use xpath.So for example this is the soap that populates the rows<xsl:variable name="Rows" select="/soap:Envelope/soap:Body/ddw1:GetListItemsResponse/ddw1:GetListItemsResult/ddw1:listitems/rs:data/z:row/>But you would need to add some predicate [] and filter the date nodes.So you can do something like this (marked in red)<xsl:variable name="Rows" select="/soap:Envelope/soap:Body/ddw1:GetListItemsResponse/ddw1:GetListItemsResult/ddw1:listitems/rs:data/z:row[ddwrt:FormatDateTime(string(@ows_Created),1033,'yyyyMMdd') &gt;= ddwrt:FormatDateTime(string(substring-after($fd,'#')),1033,'yyyyMMdd')]"/>For the filtering to work you need to have the date formatted  above as yyyyMMdd.One more thing you must have noticed is the $fd variable.This variable is created by me creating a calculated column in the list so something like this [Created]-2So basically that the xpath is doing is get me data only when the Created date  is greater than or equal to the Created date -2 which is 2 date less than the created date.Also not that when using web services in sharepoint designer and try to use the default filtering you won't get to see greater tha or less than in the option list comparison.:(Hope this helps.

  • Remove a bad/erroneous WebPart from a SharePoint page

    - by KunaalKapoor
    If you've added a poorly written webpart to your 'default.aspx' page, the consequence of this action will be that you won't be able to load the page anymore... Don't be sad, there is still a way to remove the webpart from the page :) (Yes, even removing the webpart from the webpart gallery would not solve this issue).Steps to fix this:1. Append the following query string to your URL: ?Contents=1.Once you've added Contents=1 as a query string to the webpart page's URL it will display the Webpart Maintenance Page. Example: http://mysharepointserver/default.aspx?contents=12. On that page you can now see the webparts added to the page, delete the problematic webpart.Now try reloading the default.aspx page... Tadaaa!!! you can view your page again :)3. Leave a thank you note @ comments section :)

  • A little gem from MPN&ndash;FREE online course on Architectural Guidance for Migrating Applications to Windows Azure Platform

    - by Eric Nelson
    I know a lot of technical people who work in partners (ISVs, System Integrators etc). I know that virtually none of them would think of going to the Microsoft Partner Network (MPN) learning portal to find some deep and high quality technical content. Instead they would head to MSDN, Channel 9, msdev.com etc. I am one of those people :-) Hence imagine my surprise when i stumbled upon this little gem Architectural Guidance for Migrating Applications to Windows Azure Platform (your company and hence your live id need to be a member of MPN – which is free to join). This is first class stuff – and represents about 4 hours which is really 8 if you stop and ponder :) Course Structure The course is divided into eight modules.  Each module explores a different factor that needs to be considered as part of the migration process. Module 1:  Introduction:  This section provides an introduction to the training course, highlighting the values of the Windows Azure Platform for developers. Module 2:  Dynamic Environment: This section goes into detail about the dynamic environment of the Windows Azure Platform. This session will explain the difference between current development states and the Windows Azure Platform environment, detail the functions of roles, and highlight development considerations to be aware of when working with the Windows Azure Platform. Module 3:  Local State: This session details the local state of the Windows Azure Platform. This section details the different types of storage within the Windows Azure Platform (Blobs, Tables, Queues, and SQL Azure). The training will provide technical guidance on local storage usage, how to write to blobs, how to effectively use table storage, and other authorization methods. Module 4:  Latency and Timeouts: This session goes into detail explaining the considerations surrounding latency, timeouts and how to assess an IT portfolio. Module 5:  Transactions and Bandwidth: This session details the performance metrics surrounding transactions and bandwidth in the Windows Azure Platform environment. This session will detail the transactions and bandwidth costs involved with the Windows Azure Platform and mitigation techniques that can be used to properly manage those costs. Module 6:  Authentication and Authorization: This session details authentication and authorization protocols within the Windows Azure Platform. This session will detail information around web methods of authorization, web identification, Access Control Benefits, and a walkthrough of the Windows Identify Foundation. Module 7:  Data Sensitivity: This session details data considerations that users and developers will experience when placing data into the cloud. This section of the training highlights these concerns, and details the strategies that developers can take to increase the security of their data in the cloud.

  • Applications: Some more marble fun!

    - by TechTwaddle
    Well, yesterday night I was watching a tutorial on XNA when I came across this neat little trick. It was a simple XNA application with a Windows Phone logo in it and whenever the user clicked on the device the logo would move towards the click point, and I couldn't resist experimenting with the marble (; The code is written in C# using CF3.5. Here is a video of the demo,   You probably noticed that the motion of the marble towards the click point (destination) is not linear. The marble starts off with a high velocity and slows down as it reaches its destination. This is achieved by making the speed of the marble a function of the distance between marble's current position and the destination, so as the marble approaches the destination point, the distance between them reduces and so does the speed, until it becomes zero. More on the code and the logic behind it in the next post. What I'd like to do next is, instead of making the marble stop at the click point, it should continue to move beyond it, bounce around the screen a few times and eventually come to a stop after a while. Let's see how that goes.

Most of the stories there seem to weird to be true: no developer would write software like that right? And then you run into a little nugget of code one of your co-workers wrote. And then you realize: "Hey, it happens everywhere!" Look at this piece of art I found in our codebase recently: public static decimal ToDecimal(this string input) {     System.Globalization.CultureInfo cultureInfo = System.Globalization.CultureInfo.InstalledUICulture;     var numberFormatInfo = (System.Globalization.NumberFormatInfo)cultureInfo.NumberFormat.Clone();     int dotIndex = input.IndexOf(".");     int commaIndex = input.IndexOf(",");     if (dotIndex > commaIndex)         numberFormatInfo.NumberDecimalSeparator = ".";     else if (commaIndex > dotIndex)         numberFormatInfo.NumberDecimalSeparator = ",";     decimal result;     if (decimal.TryParse(input, System.Globalization.NumberStyles.Float, numberFormatInfo, out result))         return result;     else         throw new Exception(string.Format("Invalid input for decimal parsing: {0}. Decimal separator: {1}.", input, numberFormatInfo.NumberDecimalSeparator)); }  Me and a collegue have been looking long and hard at this and what we concluded was the following: Apparently, we don't trust our users to be able to correctly set the culture in Windows. Users aren't able to determine if they should tell Windows to use a decimal point or a comma to display numbers. So what we've done here is make sure that whatever the user enters, we'll translate that into whatever the user WANTS to enter instead of what he actually did. So if you set your locale to US, since you're a US citizen, but you want to enter the number 12.34 in the Dutch style (because, you know, the Dutch are way cooler with numbers) so you enter 12,34 we will understand this and respect your wishes! Of course, if you change your mind and in the next input field you decide to use the decimal dot again, that's fine with us as well. We will do the hard work. Now, I am all for smart software. Software that can handle all sorts of input the user can think of. But this feels a little uhm, I don't know.. wrong.. Or am I too old fashioned?

  • Add control to grid from code behind in Silverlight

    - by Emanuele Bartolesi
    In this post I show how you can easily add a control to a silverlight grid layout from code behind. First you draw the grid in the xaml. <Grid x:Name="LayoutRoot" Background="Red"> <Grid.RowDefinitions> <RowDefinition Height="20"> </RowDefinition> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="300"> </ColumnDefinition> </Grid.ColumnDefinitions> </Grid> Now in the page constructor add the following code. public MainPage() { InitializeComponent(); var myButton = new Button { Name = "btnOk", Content = "Ok", }; myButton.SetValue(Grid.RowProperty, 1); myButton.SetValue(Grid.ColumnProperty, 1); myButton.Click += myButton_Click; LayoutRoot.Children.Add(myButton); } Also add the evento of the button. void myButton_Click(object sender, RoutedEventArgs e) { } The code needs no comment because it’s very simple. The only important thing is the method SetValue because it is used to set XAML attribute of element. For a better understanding I have created an example that you can download from here.

  • Weird bug in Visual Studio 11 Beta when running on Windows 8

    - by raccoon_tim
    With the Windows 8 Consumer Preview version out in the open and the Visual Studio 11 Beta also available, I’ve been putting some more effort into trying them both out. The first impression of the new Visual Studio 11 build was: Why doesn’t it work at all on Windows 8?! The issues I encountered were odd to say the least. Visual Studio did install correctly, which was a good sign, but when I started it, I was greeted with a multitude of popups each telling me that some package could not be loaded. So I clicked away for quite some time to finally be greeted by the new default visual style of Visual Studio. The next thing I wanted to do was start a new project so I pressed “New Project” and got the “Microsoft.VisualStudio.Dialogs.DialogInitializationException” exception. After some pondering and even submitting a bug report I found another already reported bug “http://connect.microsoft.com/VisualStudio/feedback/details/727578/vs-do-not-work-with-finnish-number-format-on-w8-64-bit”. It turns out that the dialog initialization failure has something to do with the packages no being loaded and following the presented workaround helped. The trick is to change the negative number sign to “-“ (U+002D) from the additional settings of your regional settings. This issue appears to have a wider reach than just Visual Studio as I heard at TechDays Finland 2012 that the same fix has to be made when using Hyper-V.
