  • SQL SERVER – Get Date and Time From Current DateTime – SQL in Sixty Seconds #025 – Video

    - by pinaldave
    This is 25th video of series SQL in Sixty Seconds we started a few months ago. Even though this is 25th video it seems like we have just started this few days ago. The best part of this SQL in Sixty Seconds is that one can learn something new in less than sixty seconds. There are many concepts which are not new for many but just we all have 60 seconds to refresh our memories. In this video I have touched a very simple question which I receive very frequently on this blog. Q1) How to get current date time? Q2) How to get Only Date from datetime? Q3) How to get Only Time from datetime? I have created a sixty second video on this subject and hopefully this will help many beginners in the SQL Server field. This sixty second video describes the same. Here is a similar script which I have used in the video. SELECT GETDATE() GO -- SQL Server 2000/2005 SELECT CONVERT(VARCHAR(8),GETDATE(),108) AS HourMinuteSecond, CONVERT(VARCHAR(8),GETDATE(),101) AS DateOnly; GO -- SQL Server 2008 Onwards SELECT CONVERT(TIME,GETDATE()) AS HourMinuteSeconds; SELECT CONVERT(DATE,GETDATE()) AS DateOnly; GO Related Tips in SQL in Sixty Seconds: Retrieve Current Date Time in SQL Server CURRENT_TIMESTAMP, GETDATE(), {fn NOW()} Get Time in Hour:Minute Format from a Datetime – Get Date Part Only from Datetime Get Current System Date Time Get Date Time in Any Format – UDF – User Defined Functions Date and Time Functions – EOMONTH() – A Quick Introduction DATE and TIME in SQL Server 2008 I encourage you to submit your ideas for SQL in Sixty Seconds. We will try to accommodate as many as we can. If we like your idea we promise to share with you educational material.

  • Desktop icons disappears when Nautilus is launched, until next boot

    - by Santosh
    What happens: When I log in into my Ubuntu everything is normal, I have some icons on my desktop and I can see them at this point of time. As soon as I click on the explorer (nautilus) on the Launcher bar, everything goes (disappers) and never comes. No matter how many time you click on the launcher, you can't open nautilus. I tried opening nautilus from the terminal, get the following: santosh@santosh:~$ nautilus Initializing nautilus-gdu extension ** (nautilus:2158): DEBUG: SyncDaemon already running, initializing SyncdaemonDaemon object Initializing nautilus-open-terminal extension (nautilus:2158): Gtk-CRITICAL **: gtk_action_set_visible: assertion `GTK_IS_ACTION (action)' failed (nautilus:2158): Gtk-CRITICAL **: gtk_action_set_visible: assertion `GTK_IS_ACTION (action)' failed Segmentation fault I suspect on "Segmentation fault" on the last line, whats that? I was amazed when I run this command in sudo.: santosh@santosh:~$ sudo nautilus Initializing nautilus-gdu extension ** (nautilus:2216): DEBUG: Syncdaemon not running, waiting for it to start in NameOwnerChanged Initializing nautilus-open-terminal extension (nautilus:2216): Gtk-CRITICAL **: gtk_action_set_visible: assertion `GTK_IS_ACTION (action)' failed (nautilus:2216): Gtk-CRITICAL **: gtk_action_set_visible: assertion `GTK_IS_ACTION (action)' failed Nautilus-Share-Message: Called "net usershare info" but it failed: 'net usershare' returned error 255: net usershare: cannot open usershare directory /var/lib/samba/usershares. Error No such file or directory Please ask your system administrator to enable user sharing. As soon as I type sudo nautilus and hit enter, nautilus starts and the desktop background changes (to the default which ubuntu has). Don't know why but at this point as soon as I click on Desktop (from the left pane) then nautilus closes. Did anyone has same issue? I am corrently working with commandline to do my work and its a big pain. Additional Information: Another thing I have noticed that when I want to open the location of PDF file I am reading in document viewer (by clicking the folder icon). It gives error "Could not open the containing folder" and "Failed to execute child process "nautilus" (Permission denied)". Any idea?

  • SQL SERVER – Copy Column Headers from Resultset – SQL in Sixty Seconds #027 – Video

    - by pinaldave
    SQL Server Management Studio returns results in Grid View, Text View and to the file. When we copy results from Grid View to Excel there is a common complaint that the column  header displayed in resultset is not copied to the Excel. I often spend time in performance tuning databases and I run many DMV’s in SSMS to get a quick view of the server. In my case it is almost certain that I need all the time column headers when I copy my data to excel or any other place. SQL Server Management Studio have two different ways to do this. Method 1: Ad-hoc When result is rendered you can right click on the resultset and click on Copy Header. This will copy the headers along with the resultset. Additionally, you can use the shortcut key CTRL+SHIFT+C for coping column headers along with the resultset. Method 2: Option Setting at SSMS level This is SSMS level settings and I kept this option always selected as I often need the column headers when I select the resultset. Go Tools >> Options >> Query Results >> SQL Server >> Results to Grid >> Check the Box “Include column header when copying or saving the results.” Both of the methods are discussed in following SQL in Sixty Seconds Video. Here is the code used in the video.

  • Reflections based on distance from plane

    - by Andrea Benedetti
    Let's consider, for example, a surface like the volleyball court, we can see that legs and shoes of the players are reflected, with a blur effect, but body and stadium don't (as each object not near to the court). I've already made a reflection effect, but it works as a specular reflection, and I need to achieve an effect like the photo above. So, I would like to make a reflection that is based on the distance between the object and the plane, in this manner a close object would reflect more than an object that is positioned far away from the plane. What is the best way to achieve this effect? My first idea was to use the depth value (taken from the reflected camera), and use that value to blend between reflection and court. But I don't know if it's a correct way. Edit: as rendering engine I use Ogre that already provides a reflections system: reflecting the camera through a plane (obviously I can select the models to draw from the reflected camera). After a render to texture pass I can blend the reflected texture with the original plane. So, if possible, I'm looking for a way that best suits my system.

  • How to troubleshoot a remote wmi query/access failure?

    - by Roman
    Hi I'm using Powershell to query a remote computer in a domain for a wmi object, eg: "gwmi -computer test -class win32_bios". I get this error message: Value does not fall within the expected range Executing the query local under the same user works fine. It seems to happen on both windows 2003 and also 2008 systems. The user that runs the shell has admin rights on the local and remote server. I checked wmi and dcom permissions as far as I know how to do this, they seem to be the same on a server where it works, and another where it does not. I think it is not a network issue, all ports are open that are needed, and it also happens within the same subnet. When sniffing the traffic we see the following errors: RPC: c/o Alter Cont Resp: Call=0x2 Assoc Grp=0x4E4E Xmit=0x16D0 Recv=0x16D0 Warning: GssAPIMechanism is not found, either caused by not reassembled, conversation off or filtering. And an errormessage from Kerberos: Kerberos: KRB_ERROR - KDC_ERR_BADOPTION (13) The option code in the packet is 0x40830000 Any idea what I should look into?

  • preparing to migrate MOSS 2007 SP1 content into new server with MOSS 2007 SP2 with the same server n

    - by Albert Widjaja
    To All Experts here, I'd like to perform a MOSS server content migration from the existing single instance server (SQL Server 2008, Windows Server 2008, SharePoint 2007 SP1) all in one and by maintaining the server name only, here's what I had in my migration plan document outline: I have created the new Windows Server 2008 R2 + SQL Server 2008 SP1 and MOSS 2007 SP2 after that: Backup MOSS_ContentDB from SQL Server 2008 SSMS (does this enough to cover all top level sites and its content in the library and doc. repository ?) Backup all top level sites from CA site using the CA Sites backup and restore tools. turn off the old MOSSDEV01 (current server) rename the existing server (TempServ01) into MOSSDEV01 (so that the user bookmark and other link inside MOSS site still working) perform restore of the DB restore the site collection and its content from the backup is that the correct way to do it ? I haven't execute the server configuration wizard to create the same port number of the SSP, CA and the SQL Server DB yet. Any idea and suggestion would be greatly appreciated Thanks.

  • Applying memory limits to screen sessions

    - by CollinJSimpson
    You can set memory usage limits for standard Linux applications in: /etc/security/limits.conf Unfortunately, I previously thought these limits only apply to user applications and not system services. This means that users can by bypass their limits by launching applications through a system service such as screen. I'd like to know if it's possible to let users use screen but still enforce application limits. Jeff had the great idea of using nohup which obeys user limits (wonderful!), but I would still like to know if it's possible to mimic the useful windowing features of screen. EDIT: It seems my screen sessions are now obeying my hard address space limits defined in /etc/security/limits.conf. I must have been making some mistake. I recently installed cpulimit, but I doubt that's the solution.Thanks for the nohup tip, Jeff! It's very useful. Link to CPU Limit package

  • Torrents: Can I protect my software by sending wrong bytes?

    - by martijn-courteaux
    Hi, It's a topic that everyone interests. How can I protect my software against stealing, hacking, reverse engineering? I was thinking: Do my best to protect the program for reverse engineering. Then people will crack it and seed it with torrents. Then I download my own cracked software with a torrent with my own torrent-software. My own torrent-software has then to seed incorrect data (bytes). Of course it has to seed critical bytes. So people who want to steal my software download my wrong bytes. Just that bytes that are important to startup, saving and loading data, etc... So if the stealer download from me (and seed it later) can't do anything with it, because it is broken. Is this idea relevant? Maybe, good torrent-clients check hashes from more peers to check if the packages (containing my broken bytes) I want to seed are correct or not? Thanks

  • What is the Xbox360's D3DRS_VIEWPORTENABLE equivalent on WinXP D3D9?

    - by Jim Buck
    I posted this on StackOverlow, but of course it should be posted here. I am maintaining a multiplatform codebase for Xbox360 and WinXP. I am seeing an issue on the XP side that appears to be related to D3DRS_VIEWPORTENABLE on the Xbox360 version not having an equivalent on WinXP D3D9. This article had an interesting idea, but the only way to construct an identity matrix is to supply negative numbers to D3DVIEWPORT9::X and D3DVIEWPORT9::Height, but they are unsigned numbers. (I tried to put in negative numbers anyway, but nothing interesting happened.) So, how does one emulate the behavior of D3DRS_VIEWPORTENABLE under WinXP/D3D9? (For clarity, the result I'm seeing is that a 2d screen-aligned quad works fine on Xbox360 but is offset/stretched on WinXP. In fact, the (0, 0) starts in the center of the screen on WinXP instead of in the lower-left corner like on the Xbox360 as a result of applying the viewport transform.) Update: I didn't have an Xbox360 devkit at the time I wrote up this question, but I've since gotten one. I commented out the disabling of the D3DRS_VIEWPORTENABLE state, and the exact same behavior resulted on the Xbox360 as on the WinXP build. So, there must be some DirectX magic to bridge the gap here for emulating D3DRS_VIEWPORTENABLE being turned off on WinXP.

  • DIVIDE vs division operator in #dax

    - by Marco Russo (SQLBI)
    Alberto Ferrari wrote an interesting article about DIVIDE performance in DAX. This new function has been introduced in SQL Server Analysis Services 2012 SP1, so it is available also in Excel 2013 (which still doesn’t have other features/fixes introduced by following Cumulative Updates…). The idea that instead of writing: IF ( Sales[Quantity] <> 0, Sales[Amount] / Sales[Quantity], BLANK () ) you can write: DIVIDE ( Sales[Amount], Sales[Quantity] ) There is a third optional argument in DIVIDE that defines the result in case the denominator (second argument) is zero, and by default its value is BLANK, so I omitted the third argument in my example. Using DIVIDE is very important, especially when you use a measure in MDX (for example in an Excel PivotTable) because it raise the chance that the non empty evaluation for the result is evaluated in bulk mode instead of cell-by-cell. However, from a DAX point of view, you might find it’s better to use the standard division operator removing the IF statement. I suggest you to read Alberto’s article, because you will find that an expression applying a filter using FILTER is faster than using CALCULATE, which is against any rule of thumb you might have read until now! Again, this is not always true, and depends on many conditions – trying to simplify, we might say that for a simple calculation, the query plan generated by FILTER could be more efficient – but, as usual, it depends, and 90% of the times using FILTER instead of CALCULATE produces slower performance. Do not take anything for granted, and always check the query plan when performance are your first issue!

  • This is the End of Business as Usual...

    - by Michael Snow
    This week, we'll be hosting our last Social Business Thought Leader Series Webcast for 2012. Our featured guest this week will be Brian Solis of Altimeter Group. As we've been going through the preparations for Brian's webcast, it became very clear that an hour's time is barely scraping the surface of the depth of Brian's insights and analysis. Accordingly, in the spirit of sharing Brian's perspective for all of our readers, we'll be featuring guest posts all this week pulled from Brian's larger collection of blog postings on his own website. If you like what you've read here this week, we highly recommend digging deeper into his tome of wisdom. Guest Post by Brian Solis, Analyst, Altimeter Group as originally featured on his site with the minor change of the video addition at the beginning of the post. This is the End of Business as Usual and the Beginning of a New Era of Relevance - Brian Solis, Principal Analyst, Altimeter Group The Times They Are A-Changin’ Come gather ’round people Wherever you roam And admit that the waters Around you have grown And accept it that soon You’ll be drenched to the bone If your time to you Is worth savin’ Then you better start swimmin’ Or you’ll sink like a stone For the times they are a-changin’. - Bob Dylan I’m sure you are wondering why I chose lyrics to open this article. If you skimmed through them, stop here for a moment. Go back through the Dylan’s words and take your time. Carefully read, and feel, what it is he’s saying and savor the moment to connect the meaning of his words to the challenges you face today. His message is as important and true today as it was when they were first written in 1964. The tide is indeed once again turning. And even though the 60s now live in the history books, right here, right now, Dylan is telling us once again that this is our time to not only sink or swim, but to do something amazing. This is your time. This is our time. But, these times are different and what comes next is difficult to grasp. How people communicate. How people learn and share. How people make decisions. Everything is different now. Think about this…you’re reading this article because it was sent to you via email. Yet more people spend their online time in social networks than they do in email. Duh. According to Nielsen, of the total time spent online 22.5% are connecting and communicating in social networks. To put that in perspective, the time spent in the likes of Facebook, Twitter, and Youtube is greater than online gaming at 9.8%, email at 7.6% and search at 4%. Imagine for a moment if you and I were connected to one another in Facebook, which just so happens to be the largest social network in the world. How big? Well, Facebook is the size today of the entire Internet in 2004. There are over 1 billion people friending, Liking, commenting, sharing, and engaging in Facebook…that’s roughly 12% of the world’s population. Twitter has over 200 million users. Ever hear of tumblr? More time is spent on this popular microblogging community than Twitter. The point is that the landscape for communication and all that’s affected by human interaction is profoundly different than how you and I learned, shared or talked to one another yesterday. This transformation is only becoming more pervasive and, it’s not going back. Survival of the Fitting But social media is just one of the channels we can use to reach people. I must be honest. I’m as much a part of tomorrow as I am of yesteryear. It’s why I spend all of my time researching the evolution of media and its impact on business and culture. Because of you, I share everything I learn in newsletters, emails, blogs, Youtube videos, and also traditional books. I’m dedicated to helping everyone not only understand, but grasp the change that’s before you. Technologies such as social, mobile, virtual, augmented, et al compel us adapt our story and value proposition and extend our reach to be part of communities we don’t realize exist. The people who will keep you in business or running tomorrow are the very people you’re not reaching today. Before you continue to read on, allow me to clarify my point of view. My inspiration for writing this is to help you augment, not necessarily replace, the programs you’re running today. We must still reach those whom matter to us in the ways they prefer to be engaged. To reach what I call the connected consumer of Geneeration-C we must too reach them in the ways they wish to be engaged. And in all of my work, how they connect, talk to one another, influence others, and make decisions are not at all like the traditional consumers of the past. Nor are they merely the kids…the Millennial. Connected consumers are representative across every age group and demographic. As you can see, use of social networks, media sharing sites, microblogs, blogs, etc. equally span across Gen Y, Gen X, and Baby Boomers. The DNA of connected customers is indiscriminant of age or any other demographic for that matter. This is more about psychographics, the linkage of people through common interests (than it is their age, gender, education, nationality or level of income. Once someone is introduced to the marvels of connectedness, the sensation becomes a contagion. It touches and affects everyone. And, that’s why this isn’t going anywhere but normalcy. Social networking isn’t just about telling people what you’re doing. Nor is it just about generic, meaningless conversation. Today’s connected consumer is incredibly influential. They’re connected to hundreds and even thousands of other like-minded people. What they experiences, what they support, it’s shared throughout these networks and as information travels, it shapes and steers impressions, decisions, and experiences of others. For example, if we revisit the Nielsen research, we get an idea of just how big this is becoming. 75% spend heavily on music. How does that translate to the arts? I’d imagine the number is equally impressive. If 53% follow their favorite brand or organization, imagine what’s possible. Just like this email list that connects us, connections in social networks are powerful. The difference is however, that people spend more time in social networks than they do in email. Everything begins with an understanding of the “5 W’s and H.E.” – Who, What, When, Where, How, and to What Extent? The data that comes back tells you which networks are important to the people you’re trying to reach, how they connect, what they share, what they value, and how to connect with them. From there, your next steps are to create a community strategy that extends your mission, vision, and value and it align it with the interests, behavior, and values of those you wish to reach and galvanize. To help, I’ve prepared an action list for you, otherwise known as the 10 Steps Toward New Relevance: 1. Answer why you should engage in social networks and why anyone would want to engage with you 2. Observe what brings them together and define how you can add value to the conversation 3. Identify the influential voices that matter to your world, recognize what’s important to them, and find a way to start a dialogue that can foster a meaningful and mutually beneficial relationship 4. Study the best practices of not just organizations like yours, but also those who are successfully reaching the type of people you’re trying to reach – it’s benching marking against competitors and benchmarking against undefined opportunities 5. Translate all you’ve learned into a convincing presentation written to demonstrate tangible opportunity to your executive board, make the case through numbers, trends, data, insights – understanding they have no idea what’s going on out there and you are both the scout and the navigator (start with a recommended pilot so everyone can learn together) 6. Listen to what they’re saying and develop a process to learn from activity and adapt to interests and steer engagement based on insights 7. Recognize how they use social media and innovate based on what you observe to captivate their attention 8. Align your objectives with their objectives. If you’re unsure of what they’re looking for…ask 9. Invest in the development of content, engagement 10. Build a community, invest in values, spark meaningful dialogue, and offer tangible value…the kind of value they can’t get anywhere else. Take advantage of the medium and the opportunity! The reality is that we live and compete in a perpetual era of Digital Darwinism, the evolution of consumer behavior when society and technology evolve faster than our ability to adapt. This is why it’s our time to alter our course. We must connect with those who are defining the future of engagement, commerce, business, and how the arts are appreciated and supported. Even though it is the end of business as usual, it is the beginning of a new age of opportunity. The consumer revolution is already underway, and the question is: How do you better understand the role you play in this production as a connected or social consumer as well as business professional? Again, this is your time to define a new era of engagement and relevance.

  • Some SharePoint NDA Information

    - by Sahil Malik
    Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). Many years ago, at the last to last to last MVP summit, Microsoft was kind enough to share with us what they were thinking wayyyyyyyyyyyy ahead! I specially remember John Durant talking about the specific enhancements planned for SharePoint 2010 development experience. If you haven’t seen John Durant talking on stage, the guy has more enthusiasm than tiger woods in Amsterdam! The energy of his presentations is simply amazing. So, I pulled out my phone, and I snapped a picture! And, I emailed that picture to everyone in the MVP land, and Microsoft land, saying “We have evidence”, i.e. here are the promises that were made, and dammit we’ll see by the time you release SP2010 how many of these do you actually release. Here is the picture ladies and gentlemen -     It’s a good karate chop action shot isn’t it? Of course, we were all immediately warned not to share any of this seriously strictly NDA information at the time. Well, now that the information is out in the world, I can finally share now, this small tidbit of how far ahead Microsoft is thinking in their plans. Frankly, I wouldn’t be surprised, if today that they have a very clear idea what SharePoint vNext will be all about, or should I say vNextvNext? Have fun! Comment on the article ....

  • A Simple Approach For Presenting With Code Samples

    - by Jesse Taber
    Originally posted on: http://geekswithblogs.net/GruffCode/archive/2013/07/31/a-simple-approach-for-presenting-with-code-samples.aspxI’ve been getting ready for a presentation and have been struggling a bit with the best way to show and execute code samples. I don’t present often (hardly ever), but when I do I like the presentation to have a lot of succinct and executable code snippets to help illustrate the points that I’m making. Depending on what the presentation is about, I might just want to build an entire sample application that I would run during the presentation. In other cases, however, building a full-blown application might not really be the best way to present the code. The presentation I’m working on now is for an open source utility library for dealing with dates and times. I could have probably cooked up a sample app for accepting date and time input and then contrived ways in which it could put the library through its paces, but I had trouble coming up with one app that would illustrate all of the various features of the library that I wanted to highlight. I finally decided that what I really needed was an approach that met the following criteria: Simple: I didn’t want the user interface or overall architecture of a sample application to serve as a distraction from the demonstration of the syntax of the library that the presentation is about. I want to be able to present small bits of code that are focused on accomplishing a single task. Several of these examples will look similar, and that’s OK. I want each sample to “stand on its own” and not rely much on external classes or methods (other than the library that is being presented, of course). “Debuggable” (not really a word, I know): I want to be able to easily run the sample with the debugger attached in Visual Studio should I want to step through any bits of code and show what certain values might be at run time. As far as I know this rules out something like LinqPad, though using LinqPad to present code samples like this is actually a very interesting idea that I might explore another time. Flexible and Selectable: I’m going to have lots of code samples to show, and I want to be able to just package them all up into a single project or module and have an easy way to just run the sample that I want on-demand. Since I’m presenting on a .NET framework library, one of the simplest ways in which I could execute some code samples would be to just create a Console application and use Console.WriteLine to output the pertinent info at run time. This gives me a “no frills” harness from which to run my code samples, and I just hit ‘F5’ to run it with the debugger. This satisfies numbers 1 and 2 from my list of criteria above, but item 3 is a little harder. By default, just running a console application is going to execute the ‘main’ method, and then terminate the program after all code is executed. If I want to have several different code samples and run them one at a time, it would be cumbersome to keep swapping the code I want in and out of the ‘main’ method of the console application. What I really want is an easy way to keep the console app running throughout the whole presentation and just have it run the samples I want when I want. I could setup a simple Windows Forms or WPF desktop application with buttons for the different samples, but then I’m getting away from my first criteria of keeping things as simple as possible. Infinite Loops To The Rescue I found a way to have a simple console application satisfy all three of my requirements above, and it involves using an infinite loop and some Console.ReadLine calls that will give the user an opportunity to break out and exit the program. (All programs that need to run until they are closed explicitly (or crash!) likely use similar constructs behind the scenes. Create a new Windows Forms project, look in the ‘Program.cs’ that gets generated, and then check out the docs for the Application.Run method that it calls.). Here’s how the main method might look: 1: static void Main(string[] args) 2: { 3: do 4: { 5: Console.Write("Enter command or 'exit' to quit: > "); 6: var command = Console.ReadLine(); 7: if ((command ?? string.Empty).Equals("exit", StringComparison.OrdinalIgnoreCase)) 8: { 9: Console.WriteLine("Quitting."); 10: break; 11: } 12: 13: } while (true); 14: } The idea here is the app prompts me for the command I want to run, or I can type in ‘exit’ to break out of the loop and let the application close. The only trick now is to create a set of commands that map to each of the code samples that I’m going to want to run. Each sample is already encapsulated in a single public method in a separate class, so I could just write a big switch statement or create a hashtable/dictionary that maps command text to an Action that will invoke the proper method, but why re-invent the wheel? CLAP For Your Own Presentation I’ve blogged about the CLAP library before, and it turns out that it’s a great fit for satisfying criteria #3 from my list above. CLAP lets you decorate methods in a class with an attribute and then easily invoke those methods from within a console application. CLAP was designed to take the arguments passed into the console app from the command line and parse them to determine which method to run and what arguments to pass to that method, but there’s no reason you can’t re-purpose it to accept command input from within the infinite loop defined above and invoke the corresponding method. Here’s how you might define a couple of different methods to contain two different code samples that you want to run during your presentation: 1: public static class CodeSamples 2: { 3: [Verb(Aliases="one")] 4: public static void SampleOne() 5: { 6: Console.WriteLine("This is sample 1"); 7: } 8:   9: [Verb(Aliases="two")] 10: public static void SampleTwo() 11: { 12: Console.WriteLine("This is sample 2"); 13: } 14: } A couple of things to note about the sample above: I’m using static methods. You don’t actually need to use static methods with CLAP, but the syntax ends up being a bit simpler and static methods happen to lend themselves well to the “one self-contained method per code sample” approach that I want to use. The methods are decorated with a ‘Verb’ attribute. This tells CLAP that they are eligible targets for commands. The “Aliases” argument lets me give them short and easy-to-remember aliases that can be used to invoke them. By default, CLAP just uses the full method name as the command name, but with aliases you can simply the usage a bit. I’m not using any parameters. CLAP’s main feature is its ability to parse out arguments from a command line invocation of a console application and automatically pass them in as parameters to the target methods. My code samples don’t need parameters ,and honestly having them would complicate giving the presentation, so this is a good thing. You could use this same approach to invoke methods with parameters, but you’d have a couple of things to figure out. When you invoke a .NET application from the command line, Windows will parse the arguments and pass them in as a string array (called ‘args’ in the boilerplate console project Program.cs). The parsing that gets done here is smart enough to deal with things like treating strings in double quotes as one argument, and you’d have to re-create that within your infinite loop if you wanted to use parameters. I plan on either submitting a pull request to CLAP to add this capability or maybe just making a small utility class/extension method to do it and posting that here in the future. So I now have a simple class with static methods to contain my code samples, and an infinite loop in my ‘main’ method that can accept text commands. Wiring this all up together is pretty easy: 1: static void Main(string[] args) 2: { 3: do 4: { 5: try 6: { 7: Console.Write("Enter command or 'exit' to quit: > "); 8: var command = Console.ReadLine(); 9: if ((command ?? string.Empty).Equals("exit", StringComparison.OrdinalIgnoreCase)) 10: { 11: Console.WriteLine("Quitting."); 12: break; 13: } 14:   15: Parser.Run<CodeSamples>(new[] { command }); 16: Console.WriteLine("---------------------------------------------------------"); 17: } 18: catch (Exception ex) 19: { 20: Console.Error.WriteLine("Error: " + ex.Message); 21: } 22:   23: } while (true); 24: } Note that I’m now passing the ‘CodeSamples’ class into the CLAP ‘Parser.Run’ as a type argument. This tells CLAP to inspect that class for methods that might be able to handle the commands passed in. I’m also throwing in a little “----“ style line separator and some basic error handling (because I happen to know that some of the samples are going to throw exceptions for demonstration purposes) and I’m good to go. Now during my presentation I can just have the console application running the whole time with the debugger attached and just type in the alias of the code sample method that I want to run when I want to run it.

  • Windows 7: app crashing/hanging on "save as" dialog

    - by Fuxi
    now this is really annoying - I'm having a global problem in Windows 7: when using the system's "save as"-file dialog, the main app will just hang. the mouse-cursor is showing progress, the whole app is hanging and I need to terminate it manually. it's happening with every app! (notepad, word, graphics app). I'm assuming it's something with the system enumerating the harddisk-drivenames or something. any idea how to fix this? by the way - when viewing the problem details - it's telling the module - it's msonsext.dll, looks like some office thing to me.

  • Load and Web Performance Testing using Visual Studio Ultimate 2010-Part 2

    - by Tarun Arora
    Welcome back, in part 1 of Load and Web Performance Testing using Visual Studio 2010 I talked about why Performance Testing the application is important, the test tools available in Visual Studio Ultimate 2010 and various test rig topologies. In this blog post I’ll get into the details of web performance & load tests as well as why it’s important to follow a goal based pattern while performance testing your application. Tools => Options => Test Tools Have you visited the treasures of Visual Studio Menu bar tools => Options => Test Tools lately? The options to enable disable prompts on creating, editing, deleting or running manual/automated tests can be controller from here. The default test project language and default test types created on a new test project creation could be selected/unselected from here. Ever wondered how you can change the default limit of 25 test results, this can again be changed from here. If you record a lot of Web Tests and wish for the web test recorder to start with “that” URL populated, well this again can be specified from here. If you haven’t so far, I would urge you to spend 2 minutes in the test tools options.   Test Menu => Ready Steady Test Action! The Test tools are under the Test Menu in Visual Studio, apart from being able to create a new Test and Test List you can also load an existing vsmdi file. You can also manage your test controllers from here. A solution can have one or more test setting files, but there can only be one active test settings file at any time. Again, this selection can be done from here.  You can open the various test windows from under the windows option from the test menu. If you open the Test view window you will see that you have the option to group the tests by work items, project, test type, etc. You can set these properties by right clicking a test in the test list and choosing properties from the context menu.    So, what is a vsmdi file? vsmdi stands for Visual Studio Test Metadata File. Placed under the Solution Items this file keeps track of the list of unit tests in your solution. If you open the vsmdi file as an xml file you will see a series of Test Links nested with in the list Test List tags along with the Run Configuration tag. When in visual studio you run tests, the IDE looks at the vsmdi file to see what tests need to be run. You also have the option of using the vsmdi file in your team builds to specify which tests need to run as part of the build. Refer here for a walkthrough from a fellow blogger on how to use the vsmdi file in the team builds. Web Performance Test – The Truth! In Visual Studio 2010 “Web Tests” have been renamed to “Web Performance Tests”. Apart from renaming this test type there have been several improvements to this test type in visual studio 2010. I am very active on the MSDN Visual Studio And Load Testing forum and a frequent question from many users is “Do Web Tests support Pages that run JavaScript?” I will start with a little bit of background before answering this question. Web Performance Tests operate at the HTTP Layer, but why? To enable you to generate high loads with a relatively low amount of hardware, Web performance tests are driven at the protocol layer rather than instantiating a browser.The most common source of confusion is that users do not realize Web Performance Tests work at the HTTP layer. The tool adds to that misconception. After all, you record in IE, and when running a Web test you can select which browser to use, and then the result viewer shows the results in a browser window. So that means the tests run through the browser, right? NO! The Web test engine works at the HTTP layer, and does not instantiate a browser. What does that mean? In the diagram below, you can see there are no browsers running when the engine is sending and receiving requests. Does that mean I can’t test pages that use Java script? The best example for java script generating HTTP traffic is AJAX calls. The most common example of browser plugins are Silverlight or Flash. The Web test recorder will record HTTP traffic from AJAX calls and from most (but not all) browser plugins. This means you will still be able to web performance test pages that use java script or plugin and play back the results but the playback engine will not show the java script or plug in results in the ‘browser control’. If you want to test the page behaviour as a result of the java script or plug in consider using Coded UI Tests. This page looks like it failed, when in fact it succeeded! Looking closely at the response, and subsequent requests, it is clear the operation succeeded. As stated above, the reason why the browser control is pasting this message is because java script has been disabled in this control. So, to reiterate, the web performance test recorder: - Sends and receives data at the HTTP layer. - Does NOT run a browser. - Does NOT run java script. - Does NOT host ActiveX controls or plugins. There is a great series of blog posts from Ed Glas, i would highly recommend his blog to any one performing Load/Performance testing through Visual Studio. Demo – Web Performance Test [Demo] - Visual Studio Ultimate 2010: Test Settings and Configuration   [Demo]–Visual Studio Ultimate 2010: Web Performance Test   In this short video I try and answer the following questions, Why is performance Testing important? How does Visual Studio Help you performance Test your applications? How do i record a web performance test? How do make a web performance test data driven, transaction driven, loop driven, convert to code, add validations? Best practices for recording Web Performance Tests. I have a web performance test, what next? Creating the Web Performance Test was the first step towards load testing your application. Now that we have the base test we can test the page behaviour when N-users access the page. Have you ever had the head of business call you and mention that the marketing team has done a fantastic job and are expecting increased traffic on the web site, can the website survive the weekend with that additional load? This is the perfect opportunity to capacity test your application to see how your website holds up under various levels of load, you can work the results backwards to see how much hardware you may need to scale up your application to survive the weekend. Apart from that it is always a good idea to have some benchmarks around how the application performs under light loads for short duration, under heavy load for long duration and soak test the application run a constant load for a very week or two to record the effects of constant load for really long durations, this is a great way of identifying how your application handles the default IIS application pool reset which by default is configured to once every 25 hours. These bench marks will act as the perfect yard stick to measure performance gains when you start making improvements. BUT there are some best practices! => Goal Based Load Testing Approach Since the subject is vast and there are a lot of things to measure and analyse, … it is very easy to get distracted from the real goal!  You can optimize your application once you know where the pain points are. There is no point performing a load test of 5000 users if your intranet application will only have a 100 simultaneous users, it is important to keep focussed on the real goals of the project. So the idea is to have a user story around your load testing scenarios and test realistically. So it is recommended that you follow the below outline, It is an Iterative process, refine your objectives, identify the key scenarios, what is the expected workload, key metrics you want to report, record the web performance tests, simulate load and analyse results. Is your application already deployed in Production? This is great! You can analyse the IIS Logs to understand the user behaviour… But what are IIS LOGS? The IIS logs allow you to record events for each application and Web site on the Web server. You can create separate logs for each of your applications and Web sites. Logging information in IIS goes beyond the scope of the event logging or performance monitoring features provided by Windows. The IIS logs can include information, such as who has visited your site, what the visitor viewed, and when the information was last viewed. You can use the IIS logs to identify any attempts to gain unauthorized access to your Web server. How to configure IIS LOGS? For those Ninjas who already have IIS Logs configured (by the way its on by default) and need a way to analyse the IIS Logs, can use the Windows IIS Utility – Log Parser. Log Parser is a very powerful tool that provides a generic SQL-like language on top of many types of data like IIS Logs, Event Viewer entries, XML files, CSV files, File System and others; and it allows you to export the result of the queries to many output formats such as CSV, XML, SQL Server, Charts and others; and it works well with IIS 5, 6, 7 and 7.5. Frequently used Log Parser queries. Demo – Load Test [Demo]–Visual Studio Ultimate 2010: Load Testing   In this short video I try and answer the following questions, - Types of Performance Testing? - Perform Goal driven Load Testing, analyse Test Run Result and Generate a report? Recap A quick recap of what we have covered so far,     Thank you for taking the time out and reading this blog post, in part III of this blog series I’ll be getting into the details of Test Result Analysis, Test Result Drill through, Test Report Generation, Test Run Comparison, and the Asp.net Profiler.

  • How do I setup an FTP server on Windows 7?

    - by Matt Frear
    I'm having trouble getting an FTP server setup on Windows 7. I've added the service using Control Panel - Programs - Turn Windows features on and off. I can see the service has started in Control Panel - Services. But then when I fire up a Windows command-line window, cmd, I get Not connected., C:\Users\mattf>ftp localhost ftp> ls Not connected. ftp> open localhost ftp> ls Not connected. ftp> dir Not connected. ftp> quit C:\Users\mattf> And that's as far as I've got. I have no idea why this isn't working - could it be firewall settings?

  • Blank white desktop icons on new Windows 7 install

    - by SiegeX
    I just did a fresh install of Windows 7 professional on my father's Toshiba Satellite laptop and everything went smoothly except for the fact that certain desktop shortcuts appear as a blank white page. I've tried: going in and changing the icon to many different things reloading the icon cache by deleting the IconCache.db file uninstalling his Free AVG as he heard the virus scanner might be preventing it (it wasn't and he put it back.) The one thing these icons have in common is that they are shortcuts to some very old DOS executables. One of them is Word Star 2000 to give you an idea. Does anybody have any other suggestions besides what we've tried?

  • VGA cable causing resolution issue

    - by LatishS
    I recently bought a new VGA cable. When connected, Windows 7 detects my monitor as a generic plug and play monitor. The resolution goes bad with the screen blurred. This problem disappears when I connect my original VGA cable. Also Windows 7 detects my LG monitor correctly in this case. I am pretty sure it is something to do with the VGA cable but have no idea what could be the possible issue. Any pointers would be very much appreciated.

  • Trouble virtualizing application under Windows 7

    - by vtimmerm
    Hi, I'm trying to virtualize an application for Windows 7 but am running into trouble: Application will run fine in Windows 7 if installed in the base. When it is virtualized, it will run on XP, but not on Windows 7. I have tried this in three ways: Captured on XP with ThinApp 4.0 Captured on XP with ThinApp 4.5 Captured on Windows 7 with ThinApp 4.5 Even when captured on Windows 7, it will not run on Windows 7 but will run on XP. When captured with a rival product, Altiris SVS, the virtualized app runs fine on Windows 7. Any idea what could cause this behaviour? Looking at the trace file, you see that they are different right from the start when comparing Windows 7 and XP tracefiles. What could cause it to go in completely different directions? (And why does the tracefile on Windows 7 say: Operating System Unknown? Does everybody have that on Windows 7 even with 4.5?) The error message is: "Object variable or with block variable not set".

  • Port forwarding (portmap) works only locally

    - by Tag Wint
    There are four hosts hostA winXP hostB Win2003 hostC Linux RHEL hostD Linux RHEL hostA cannot connect to C and D directly, but B can hostA connects to hostB using VPN hostB and hostC belong to the same subnet1 hostD is in subnet2 From hostA I need to connect to hostC and hostD by SSH. Now I can do it as follows: 1.connecting from hostA to hostB by RDP logon and there: 2.start putty client. I'd like to omit step 1 and connect from A to C and D directly On hostB I have admin acoount and configure port forwarding as follows: netsh interface portproxy add v4tov4 listenport=N1 connectaddress=hostC_IP connectport=N2 netsh interface portproxy add v4tov4 listenport=N3 connectaddress=hostD_IP connectport=N2 netsh interface portproxy show all: Listen on IPv4: Connect to IPv4: Address Port Address Port --------------- ---------- --------------- ---------- * N1 hostC_IP N2 * N3 hostD_IP N2 Now from hostB I can connect to either C and D: ssh localhost:N1 ssh localhost:N3 from hostA ssh hostB:N1 works too, but ssh hostB:N3 DON'T I guess the reason might be different subnets, still have no idea how to fix it. What should I do?

  • How to style this form using CSS ? [closed]

    - by Rafael
    Hi all ,i'm a beginner at CSS and trying to do a NETTUTS , but there's a portion in the webpage that i don't know what exactly to do in CSS to make it look right ... I just can't get this input text boxes, textarea and the button to be aligned like that , and to be honest the tutor isn't doing a great job to clearing stuff out Using alternative and absolute positioning, and setting top and right spacing is kinda no a good idea i think ... I'm trying to align them using FlexBox feature but don't know why those elements are not moving at all ... Here's my HTML & CSS3 code (for chrome) : <section id="getAfreeQuote"> <h2>GET A FREE QUOTE</h2> <form method="post" action="#"> <input type="text" name="yourName" placeholder="YOUR NAME"/> <input type="email" name="yourEmail" placeholder="YOUR EMAIL"/> <textarea name="projectDetails" placeholder="YOUR PROJECT DETAILS."></textarea> <input type="text" name="timeScale" placeholder="YOUR TIMESCALE"/> <button>Submit</button> </form> #getAfreeQuote form { display:-webkit-box; -webkit-box-orient:vertical; height:500px; } #getAfreeQuote input[name="yourName"]{ -webkit-box-ordinal-group:1; } #getAfreeQuote input[name="yourEmail"]{ -webkit-box-ordinal-group:1; } #getAfreeQuote textarea{ -webkit-box-ordinal-group:2; } #getAfreeQuote input[name="timeScale"]{ -webkit-box-ordinal-group:3; } #getAfreeQuote button { -webkit-box-ordinal-group:4; } and the result :

    I was setting the MySQL Replication for master - slave/master - slave and Replication for master - slave its works fine but when i have enable this option in my.cnf log-slave-updates=1 for updating the master bin log my replications is starting be slower and the time Seconds_Behind_Master is growing. I use innodb engine but the DB is big. Any idea how i can improve the replication, looks like the network is not the issue. Also i was think to use binlog_format=ROW but master is using default setting for replication 'statement' and i cant reset master ;) Thanks ...

  • Double default gateway ubuntu server

    - by Elena
    I've just installed an Ubuntu server 9.10 on an EEEBox. This is my /etc/network/interfaces # The loopback network interface auto lo iface lo inet loopback auto wlan0 iface wlan0 inet static address 192.168.48.16 netmask 255.255.248.0 wireless-essid mynet auto eth0 iface eth0 inet static address xx.xx.xx.xx netmask 255.255.255.224 gateway xx.xx.yy.yy When I restart /etc/init.d/networking, I can access the eth0 ip address from the internet and I can ping the machines in my wifi network mynet. Everything works fine and I have one default gateway. But after some time if I check again the route I just find two default gateways: one is correct and is the previous one, but the other is the one of the wifi network. I have a quite low signal of mynet where my server is and sometimes the wifi just disconnect and then reconnect again. Then I think that this can be a problem and the dhcp of the wifi net, when reconnecting it also add a default gateway. Any idea on how to resolve this issue?
