  • For what purposes have YOU used T4?

    - by Chris Melinn
    T4 has existed for several years in Visual Studio, but doesn't get a lot of attention. However, for those that know it, there seems to be some very creative and useful purposes. I am researching some different ways that T4 is used, and I would appreciate to hear how YOU may have used it for real life scenarios. I am primarily interested in non-standard and creative uses. Some interesting examples: Phil Haack uses T4 to create static CSS files from .less To Generate WPF and Silverlight Dependency Properties using T4 Templates Note: I realize this is a discussion-oriented question, but the answers could be helpful to others. I have tagged it as subjective and also marked as "community wiki", so please allow the question to remain open. Thanks!

  • Ajax image upload and javascript edit on the fly with ASP.NET MVC (without saving to disk)

    - by gavss
    1) Uploadimage action gets requests from form posts. <form action="/content/uploadimage" method="post" enctype="multipart/form-data"> It reads HttpPostedFileBase stream data and sends it to the response. I need to show the image in a div container instead of sending it to the response as a file so that users can manipulate the image using jcrop. Image source is generated at runtime. I can't pass an action name to the src attribute. Is this possible using MVC and without using control viewstate? 2) I don't want to use flash or silverlight. Is there an easy ajax alternative to the method I use to get files from user?

  • Abstract Design Pattern implementation

    - by Pathachiever11
    I started learning design patterns a while ago (only covered facade and abstract so far, but am enjoying it). I'm looking to apply the Abstract pattern to a problem I have. The problem is: Supporting various Database systems using one abstract class and a set of methods and properties, which then the underlying concrete classes (inheriting from abstract class) would be implementing. I have created a DatabaseWrapper abstract class and have create SqlClientData and MSAccessData concrete class that inherit from the DatabaseWrapper. However, I'm still a bit confused about how the pattern goes as far as implementing these classes on the Client. Would I do the following?: DatabaseWrapper sqlClient = new SqlClientData(connectionString); This is what I saw in an example, but that is not what I'm looking for because I want to encapsulate the concrete classes; I only want the Client to use the abstract class. This is so I can support for more database systems in the future with minimal changes to the Client, and creating a new concrete class for the implementations. I'm still learning, so there might be a lot of things wrong here. Please tell me how I can encapsulate all the concrete classes, and if there is anything wrong with my approach. Many Thanks! PS: I'm very excited to get into software architecture, but still am a beginner, so take it easy on me. :)

  • jQuery, Ajax & PHP submit multiple forms dilemma

    - by user557563
    This is a very simple form that I have found on the web (as I am a jQuery beginner). <!-- this is my jquery --> <script> $(document).ready(function(){ $("form#submit_wall").submit(function() { var message_wall = $('#message_wall').attr('value'); var id = $('#id').attr('value'); $.ajax({ type: "POST", url: "index.php?leht=pildid", data:"message_wall="+ message_wall + "&id="+ id, cache: false, success: function(){ $("ul#wall").prepend(""+message_wall+"", ""+id+""); $("ul#wall li:first").fadeIn(); alert("Thank you for your comment!"); } }); return false; }); }); </script> <!-- this is my HTML+PHP --> some PHP ... while($row_pilt = mysql_fetch_assoc($select_pilt)){ print <form id="submit_wall"> <label for="message_wall">Share your message on the Wall</label> <input type="text" id="message_wall" /> <input type="hidden" id="id" value="'.(int)$row_pilt['id'].'"> <button type="submit">Post to wall</button> </form> and down below is my PHP script that writes to mySQL. It is a pretty straight forward script. However, it is getting little complicated when I submit it. Since I have more than one form on my page (per WHILE PHP LOOP), thus when I submit - only the FIRST form gets submitted. Furthermore, any other subsequent forms that I submit - data is being copied from the first form. Is there any jQuery functions that clear the data? - or is there a better solution. Thanks, Nick

  • Filter design for audio signal.

    - by beanyblue
    What I am trying to do is simple. I have a few .wav files. I want to remove noise and filter out specific frequencies. I don't have matlab and I intend to write my own code for all the filters. Right now, I have a way to read the .wav file and dump out the structure into a text file. My questions are the following: Can I directly apply the digital filters on this sampled data?{ ie, can I directly do a convolution between my input samples and h(n) for the filter function that i choose?). How do I choose the number of coefficients for the Window function? I have octave, so if someone can point me to anything that gives me some idea on how to process the .wav file using octave, that would be great too. I want to be able to filter out the frequency and then listen to the sound again. Is this possible with octave? I'm just a beginner with these kinds of things, so please bear with me if my questions are too naive. Any help will be great.

  • Java threading problem

    - by Krt_Malta
    Hi! I'm using multiple threads in my application. Basically I have a combo box and upon selecting Inbox, p1 resumes and p2 is suspended and upon selecting Send, p2 starts and p1 stops. Below is the code (I'm sure it's not perfect) public void modifyText(ModifyEvent e) { if (combo.getText().equals("Inbox")) { synchronized(p2) { p2.cont = false; } table.removeAll(); synchronized(p1) { p1.cont = true; p1.notify(); } } else if (combo.getText().equals("Sent")) { synchronized(p2) { p1.cont = false; } table.removeAll(); synchronized(p1) { p2.cont = true; p2.notify(); } } } }); and for P1 and P2 I have this inside their while loops: synchronized (this) { while (cont == false) try { wait(); } catch (Exception e) { } } ... As it is it's now working (I'm a beginner to threads). On pressing Sent in the combo box, I get an IllegalStateMonitorException. Could anyone help me solve the problem plz? Thanks and regards, Krt_Malta

  • PHP: Need help with simple XML.

    - by Jack
    I am beginner in PHP. I am trying to parse this xml file. <relationship> <target> <following type="boolean">true</following> <followed_by type="boolean">true</followed_by> <screen_name>xxxx</screen_name> <id type="integer">xxxx</id> </target> </relationship> I need to get the value of the field 'following type="boolean" ' and here's my code - $xml = simplexml_load_string($response); foreach($xml->children() as $child) { if ($child->getName() == 'target') { foreach($child->children() as $child_1) if ( $child_1->getName() == 'following') { $is_my_friend = (bool)$child_1; break; } break; } } but I am not getting the correct output. I think the ' type="boolean" ' part of the field is creating problems. I know this might be a very trivial problem. Kindly bear with my ignorance. Please help.

  • getting (this) at different function

    - by twen_ta
    I have couple of input fields with the class "link". All of them should start the jqueryUI dialog so this is why I bind the method to a class and not an single id. The difficulty is now that i can't use the (this) in line 12, because that gives me the identity of the dialog and not the input element. As I am an beginner I don't know how to pass a variable to this event with the element of the input field. What I want to archive is that the dialog should start from the input field and should write the result back to that input field. 1. // this is the click event for the input-field class called "link" 2. $('.link') 3. .button() 4. .click(function() { 5. $('#dialog-form').dialog('open'); 6. 7. }); 8. 9. //this is an excerpt from the opened dialog box and the write back to the input field 10. $("#dialog-form").dialog({ 11. if (bValid) { 12. $('.link').val('' + 14. name.val() + ''); 15. $(this).dialog('close'); 16. } 17. });

  • Clonezilla restore from Samba - no 'restoredisk' option

    - by MT_Head
    I used a CloneZilla LiveCD to back up a couple of Windows machines to a Samba share. Now I'm trying to restore those images, and CloneZilla won't even give me the 'restoredisk' or 'restorepart' options on the menu. I'm guessing that this is because CZ isn't recognizing a valid image... but why? Here's a listing of the folder on the Samba share: -rwxrwxrwx 1 marc users 319 May 31 03:45 blkdev.list -rwxrwxrwx 1 marc users 5307 May 31 04:41 clonezilla-img -rwxrwxrwx 1 marc users 4 May 31 04:31 disk -rwxrwxrwx 1 marc users 16091 May 31 04:31 Info-dmi.txt -rwxrwxrwx 1 marc users 11029 May 31 04:31 Info-lshw.txt -rwxrwxrwx 1 marc users 1502 May 31 04:31 Info-lspci.txt -rwxrwxrwx 1 marc users 170 May 31 04:31 Info-packages.txt -rwxrwxrwx 1 marc users 80 May 31 04:41 Info-saved-by-cmd.txt -rwxrwxrwx 1 marc users 10 May 31 04:31 parts -rwxrwxrwx 1 marc users 2097152000 May 31 04:06 sda1.ntfs-ptcl-img.gz.aa -rwxrwxrwx 1 marc users 247361656 May 31 04:08 sda1.ntfs-ptcl-img.gz.ab -rwxrwxrwx 1 marc users 823182034 May 31 04:31 sda2.ntfs-ptcl-img.gz.aa -rwxrwxrwx 1 marc users 36 May 31 03:45 sda-chs.sf -rwxrwxrwx 1 marc users 31744 May 31 03:45 sda-hidden-data-after-mbr -rwxrwxrwx 1 marc users 512 May 31 03:45 sda-mbr -rwxrwxrwx 1 marc users 315 May 31 03:45 sda-pt.parted -rwxrwxrwx 1 marc users 285 May 31 03:45 sda-pt.parted.compact -rwxrwxrwx 1 marc users 259 May 31 03:45 sda-pt.sf (I've been experimenting with various permissions trying to get this to work; that's why they're currently all "rwxrwxrwx"...) I've got my CZ LiveCD stuck in a (different) machine with a 160GB SATA disk that I'm fine with overwriting; although CZ doesn't show a directory listing, it does show that the correct folder is mounted as /home/partimag. But a moment later, after selecting either Beginner or Expert, I'm only presented with the "savedisk", "saveparts", and "exit" options. What am I doing wrong? I am confident that the initial backup was successful; I can post the log if desired, or any other information that might be germane. Edit: I've copied the contents of the folder onto a 16GB USB stick and set THAT as /home/partimag. Still nothing. What the hell is CZ looking for?

  • Windows 7 laptop constantly dropping internet connection

    - by Corbin Holbert
    I have scoured the web for an answer and failed to find one. I am using a Toshiba Satellite laptop running Windows 7 64-Bit. I have the computer connected via Wifi. Now, I am no beginner with the Internet, or anything related to computers, as I have grown up teaching everyone around me how to use computers, and went to college for IT. Everything on my network works flawlessly at all times, except for this evil laptop. The worst part is that I fixed this once before a few years back and recently had to replace the hard drive and re-install the OS, but cannot for the life of me remember what I did to make this problem go away. I am in my browser, connected to the Internet. I click a link. Suddenly no internet access. All I do is click down on the WiFi connection in the task bar, disconnect and reconnect immediately. Internet is back the moment I hit "connect." I have read many people had the same issues as I am having, but they all had triggers or other network issues. I have no trigger (this happens literally five to six times per minute no matter what I am doing) and I have no problems with my router, modem, or any other devices or computers on said network. As I am a web designer, and like to test my work live at every turn- this is going to result in this laptop being in pieces if I can't get it fixed soon. If more info is needed, let me know and I will provide. Thanks for any help offered! EDIT: Network Card: Realtek RTL8188CE Wireless LAN 802.11n PCI-E NIC Network state reads as "No Internet Access" when the problem first occurs, then magically I have Internet access for about ten seconds once I disconnect and reconnect. I have turned off IPV6, I have turned off power saving options for the network adapter, no viruses. Any new ideas? Also, I had to disconnect and reconnect four times just to get to this edit screen- and will likely have to do the same just to post it- it's that bad.

  • Can't validate mine, sudo nor root in Debian "Jessie" Gnome anymore?

    - by Janar
    I'm Debian beginner & GUI guy in a bit of trouble? Can't login as sudo/gksu/root/su nor as (main/super)user after removed user password via Gnome-user-settings. History of actions (Probably irrelevant though) Installed Debian "Jessie" GNU/Linux with xFce GUI (en-US) as only OS. HardWare is ThinkPad w510. Skipped root user password in setup, to get sudo for superuser easily. Logged in (as always had) with Gnome (3.4.x), not once with xFCE. (installed Xfce. Installed xFce only to achieve more control (easier management) over packages this way, to set-up gnome much more by mine likes. Added more jessie repros (same ones as in Wheesy stable by default but for Jessie as, Jessie only had repros for security updates by default). Installed lots of gtk(3) & gnome(3) based soft; (- restarted again after this) Installed propietary graphics card driver for mine nvidia quadro. (- restarted once again after that one) Installed more stuff related to mine work/school/devel. The actual problem Had a plan to restart again, but wanted to set up auto-login first, instead set user password to none (don't ask why / perhaps caused by being awake for a looooong time), noticed it, and set also to auto-login, but couldn't undo mine previous mistake to create new password for me. As mine password is set to none I would have expected that simply return in pass prompt for emty password field would do, but it won't authenticate. I tried Alt+F2 "gksu gedit" as well as: sudo wget "https://www.some-page.eu/file.ext" and "su" in terminals, none has applied (quite logical actually - as I'm sudoer and highest ranked super user, besides only user in computer). Current stand Everything worked & still works nice after this accident, besides this password prompts part. To spoked to log-out nor restart. Synaptic package-manager is still open with root rights (only one, that has left open prior to the issue and not closed since, just in case). Goggled for help and read some manuals/faqs/how-tos - mostly lead to sudoers file management, but not found one specifically for mine issue - so still not any smarter. Really hope, that I don't have to redo OS inst all over again, by just one stupid mistake. Thanks for your reply :-)

  • How do I (robustly) remotely execute tasks on Windows workstations in a domain?

    - by Zac B
    I'm not even sure if "robustly" is a word. Anyway. Context: We have a few hundred Windows 7 workstations on a LAN. We use AD/GPO management pretty heavily, but there are a lot of periodic and/or manual maintenance tasks we need to do that can't be done via GPO/scheduled task. For example, say I want to execute program X (which runs silently, in the background, and doesn't bother the user) on workstation Y, or say I want to execute task A on a workstation group B either on a schedule or on demand. Kicking the users off of their computers to do this (i.e. using RDP) is a no-no, and doesn't work on groups anyway. Question: What's the best way to do this that is robust enough that, after setup, I could give it to beginner support people (read: people who are phobic of the command line, and get confused with GUI interfaces more complicated than Firefox)? I'm a competent programmer, and, if there is a robust set of tools or framework out there for this type of task, I'd consider hacking something together myself if it didn't take too long. If there's some combination of tools or techniques that others use to make remote-workstation-administration doable by beginners, I have yet to find it. For those who care about the "why": I'm midlevel IT, and was told to implement a remote management solution that allows arbitrary/scheduled remote execution, with confirmation that programs actually ran remotely, and the ability to view what they returned. "Why?" I asked, "Can't I just use PsExec and the task scheduler on a dispatcher machine?" "No," I was told, "'Joe' the second-week tech is going to be in charge of this one, and he needs something simple with a GUI." What I've tried: I've played with making a bunch of one-clickable "transfer files to remote computer and run them with PsExec" batch/VB scrips, but those tend to break down and don't easily support running on customizable groups. I've played a little bit with the Windows version of Puppet, but it doesn't support arbitrary-time remote execution (it's ability to group computers into a tree/node structure is really nice though). I've used an older version of Altiris, and, while it does a lot of what I want, it's interface is awful, it's slow, crashes a lot, and is probably too expensive for management. SwiftWater's DMS solution does some of what I want, but it's very underdeveloped, closed-source (not a deal breaker but not ideal), and I get the impression that support and reliability are lacking.

  • Apache returns 403 Forbidden for alternative port vhost

    - by Wesley
    I'm having an issue getting vhosts to work on Apache 2.2, Debian 6. I have two VirtualHosts, one on port 80 and one on port 8888. The port 80 one has been created automatically by DirectAdmin, the 8888 is a custom one. It's configuration is as follows. <VirtualHost *:8888 > DocumentRoot /home/user/public_html/development ServerName www.myserver.nl ServerAlias myserver.nl <Directory "/home/user/public_html/development"> Options +Indexes +FollowSymLinks +MultiViews AllowOverride All Order Allow,deny Allow from all </Directory> </VirtualHost> Of course I also have a NameVirtualHost *:8888 The port 80 DocumentRoot is /home/user/public_html/production, which is perfectly accessible and works like a charm. The port 8888 docroot of /home/user/public_html/development is 403 forbidden though. I have compared the permissions for both folders. They seem fine to me. drwxr-xr-x 2 root root 4096 Aug 17 16:14 development drwxr-xr-x 4 root root 4096 Aug 18 04:29 production Also, the index.php file which is supposed to display when accessing through port 8888, located in /development/: -rwxr-xr-x 1 root root 41 Aug 17 16:14 index.html I have looked at my error_log and found many of the following entries, only being added to the log file when accessing through port 8888. [Sat Aug 18 04:35:09 2012] [error] [client 27.32.156.232] Symbolic link not allowed or link target not accessible: /home/user/public_html /home/user/public_html is a symbolic link that refers to /home/user/domains/mydomain/public_html. The symbolic link has the following permissions: lrwxrwxrwx 1 admin admin 29 Aug 17 15:56 public_html -> ./domains/mydomain/public_html I'm at a loss. It seems that everything is readable or executable. I've set the Directory to FollowSymLinks in the httpd.conf file, but that doesn't seem to make a difference. If I change that directory tag to <Directory "/home/admin/public_html"> (so it has FollowSymLinks on that as well) it still does not work. Any help is greatly appreciated. If I need to post more information, let me know. I'm pretty much a beginner at this stuff. .. .. UPDATE: I ended up changing the configuration to directly go to the actual path of the files, avoiding the public_html symlink altogether. That worked. Thanks for the suggestions folks. DocumentRoot /home/user/domains/mydomain/public_html/development instead of DocumentRoot /home/user/public_html/development

  • Upgrade existing WinForms applications to use the latest RadControls

    Upgrading projects to new versions can be a pain, especially when you have to update several assemblies from a single version, as is the case with RadControls for WinForms. Q1 2010 simplifies this process a lot, by giving a couple of ways (one new and one updated) to upgrade existing applications to the latest and greatest version of RadControls for WinForms: By using the new Visual Studio Extensions (VSX), available in VS2005, VS2008 and VS2010 RC; By using the updated Project Upgrade Utility. Here are the steps: Upgrading a classic Windows Forms application to the latest RadControls for WinForms by using the Visual Studio Extensions Install RadControls for WinForms Q1 2010 Open the classic Windows Forms application (VB or C#) Open the Telerik Menu and select RadControls for WinForms --> Convert to Telerik WinForms Application     Select the Telerik controls you plan to use in the application, as well as a theme, and click OK. The VSX package will add the needed assemblies to your project automatically for you.     Replace the standard controls on your form with the respective Telerik controls.     Run the application to see the result. Upgrading an older RadControls application to the latest RadControls for WinForms by using the Visual Studio Extensions Install RadControls for WinForms Q1 2010. Open your current RadControls application (VB or C#), which uses pre-Q1 2010 assembly versions. Open the Telerik Menu and select RadControls for WinForms --> Upgrade Wizard   Choose to either use the online downloader of the latest version, or to use the currently installed version. The VSX package will check what assemblies you use in your project and will upgrade them automatically.     Run the application to see the result. Upgrading an older RadControls application to the latest RadControls for WinForms by using the Project Upgrade Utility The Q1 2010 Project Upgrade Utility now features upgrading not only a single project, but all projects in a directory/solution (recursively). The tool is quite intuitive - simply choose your solution folder (or a folder with several projects)m and click Update. Feel free to leave a comment. Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • JavaScript Data Binding Frameworks

    - by dwahlin
    Data binding is where it’s at now days when it comes to building client-centric Web applications. Developers experienced with desktop frameworks like WPF or web frameworks like ASP.NET, Silverlight, or others are used to being able to take model objects containing data and bind them to UI controls quickly and easily. When moving to client-side Web development the data binding story hasn’t been great since neither HTML nor JavaScript natively support data binding. This means that you have to write code to place data in a control and write code to extract it. Although it’s certainly feasible to do it from scratch (many of us have done it this way for years), it’s definitely tedious and not exactly the best solution when it comes to maintenance and re-use. Over the last few years several different script libraries have been released to simply the process of binding data to HTML controls. In fact, the subject of data binding is becoming so popular that it seems like a new script library is being released nearly every week. Many of the libraries provide MVC/MVVM pattern support in client-side JavaScript apps and some even integrate directly with server frameworks like Node.js. Here’s a quick list of a few of the available libraries that support data binding (if you like any others please add a comment and I’ll try to keep the list updated): AngularJS MVC framework for data binding (although closely follows the MVVM pattern). Backbone.js MVC framework with support for models, key/value binding, custom events, and more. Derby Provides a real-time environment that runs in the browser an in Node.js. The library supports data binding and templates. Ember Provides support for templates that automatically update as data changes. JsViews Data binding framework that provides “interactive data-driven views built on top of JsRender templates”. jQXB Expression Binder Lightweight jQuery plugin that supports bi-directional data binding support. KnockoutJS MVVM framework with robust support for data binding. For an excellent look at using KnockoutJS check out John Papa’s course on Pluralsight. Meteor End to end framework that uses Node.js on the server and provides support for data binding on  the client. Simpli5 JavaScript framework that provides support for two-way data binding. WinRT with HTML5/JavaScript If you’re building Windows 8 applications using HTML5 and JavaScript there’s built-in support for data binding in the WinJS library.   I won’t have time to write about each of these frameworks, but in the next post I’m going to talk about my (current) favorite when it comes to client-side JavaScript data binding libraries which is AngularJS. AngularJS provides an extremely clean way – in my opinion - to extend HTML syntax to support data binding while keeping model objects (the objects that hold the data) free from custom framework method calls or other weirdness. While I’m writing up the next post, feel free to visit the AngularJS developer guide if you’d like additional details about the API and want to get started using it.

  • Integrating Twitter Into An ASP.NET Website Using OAuth

    Earlier this year I wrote an article about Twitterizer, an open-source .NET library that can be used to integrate your application with Twitter. Using Twitterizer you can allow your visitors to post tweets, view their timeline, and much more, all without leaving your website. The original article, Integrating Twitter Into An ASP.NET Website, showed how to post tweets and view a timeline to a particular Twitter account using Twitterizer 1.0. To post a tweet to a specific account, Twitterizer 1.0 uses basic authentication. Basic authentication is a very simple authentication scheme. For an application to post a tweet to JohnDoe's Twitter account, it would submit JohnDoe's username and password (along with the tweet text) to Twitter's servers. Basic authentication, while easy to implement, is not an ideal authentication scheme as it requires that the integrating application know the username(s) and password(s) of the accounts that it is connected to. Consequently, a user must share her password in order to connect her Twitter account with the application. Such password sharing is not only insecure, but it can also cause difficulties down the line if the user changes her password or decides that she no longer wants to connect her account to certain applications (but wants to remain connected to others). To remedy these issues, Twitter introduced support for OAuth, which is a simple, secure protocol for granting API access. In a nutshell, OAuth allows a user to connect an application to their Twitter account without having to share their password. Instead, the user is sent to Twitter's website where they confirm whether they want to connect to the application. Upon confirmation, Twitter generates an token that is then sent back to the application. The application then submits this token when integrating with the user's account. The token serves as proof that the user has allowed this application access to their account. (Twitter users can view what application's they're connected to and may revoke these tokens on an application-by-application basis.) In late 2009, Twitter announced that it was ending its support for basic authentication in June 2010. As a result, the code examined in Integrating Twitter Into An ASP.NET Website, which uses basic authentication, will no longer work once the cut off date is reached. The good news is that the Twitterizer version 2.0 supports OAuth. This article examines how to use Twitterizer 2.0 and OAuth from a website. Specifically, we'll see how to retrieve and display a user's latest tweets and how to post a tweet from an ASP.NET page. Read on to learn more!

  • How To Personalize the Windows Command Prompt

    - by Matthew Guay
    Command line interfaces can be downright boring, and always seem to miss out on the fresh coats of paint liberally applied to the rest of Windows.  Here’s how to add a splash of color to Command Prompt and make it unique. By default, Windows Command Prompt is white text on a black background. It get’s the job done, but maybe you want to add some color to it.   To get an overview of what we can do with the color command, let’s enter: color /? So, to get the color you want, enter color then the option for the background color followed by the font color.  For example, let’s make an old-fashioned green on black look by entering: color 02   There are a bunch of different combinations you can do, like this black background with red text. color 04 You can’t mess it up too much.  The color command won’t let you set both the font and the background to the same color, which would make it unreadable.  Also, if you want to get back to the default settings, just enter: color Now we’re back to plain-old black and white. Personalize Command Prompt Without Commands If you’d prefer to change the color without entering commands, just click on the Command Prompt icon in the top left corner of the window and select Properties. Select the Colors tab, and then choose the color you want for the screen text and background.  You can also enter your own RGB color combination if you want.   Here we entered the RGB values to get a purple background color like Ubuntu 10.04. Back in the Properties dialog, you can also change your Command Prompt font from the font tab.  Choose any font you want, as long as the one you want is one of the three listed here. Customizations you make via the Properties dialog are saved and will be used any time you open Command Prompt, but any customizations you make with the Color command are only for that session. Conclusion Whether you want to make your command prompt bright enough to cause a sunburn or old-style enough to scare a mainframe operator, with these settings, you can make Command Prompt a bit more unique.   Similar Articles Productive Geek Tips Use "Command Prompt Here" in Windows VistaVerify the Integrity of Windows Vista System FilesKeyboard Ninja: Scrolling the Windows Command Prompt With Only the KeyboardRun a Command as Administrator from the Windows 7 / Vista Run boxStart an Application Assigned to a Specific CPU in Windows Vista TouchFreeze Alternative in AutoHotkey The Icy Undertow Desktop Windows Home Server – Backup to LAN The Clear & Clean Desktop Use This Bookmarklet to Easily Get Albums Use AutoHotkey to Assign a Hotkey to a Specific Window Latest Software Reviews Tinyhacker Random Tips DVDFab 6 Revo Uninstaller Pro Registry Mechanic 9 for Windows PC Tools Internet Security Suite 2010 How to Add Exceptions to the Windows Firewall Office 2010 reviewed in depth by Ed Bott FoxClocks adds World Times in your Statusbar (Firefox) Have Fun Editing Photo Editing with Citrify Outlook Connector Upgrade Error Gadfly is a cool Twitter/Silverlight app

  • Renewed as MVP

    - by Sahil Malik
    Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). It is with great humbleness and honor that I accept Microsoft’s MVP award for 2010. This will be my .. I forget how many years, as an MVP. So suffice to say, I was a lot younger when I first got the MVP award, but also the excitement never dies. Don’t get me wrong, I’m still young, foolish and weird :). (and good looking, might I add) I’d like to share a few things with you on what I have learnt being a part of this very prestigious program that I am so unworthy of. Never aim to be an MVP. Let it be a consequence of what you already are. Always be down to earth, just because you’re an MVP doesn’t mean you’re better than anyone else. The biggest reward of the MVP program, yes much bigger than the free top notch MSDN subscription, is the amazing interaction you will have with other fellow MVPs, and incredibly smart people in the community in general. Get involved in the community, for your own sake! You will learn so much from your peers, it is a very very rewarding experience. Learn, Learn and Learn! Never under estimate the power of knowledge. Both technical and otherwise. I thank each one of you for all the attention you have given me over the past many years. And a very special thanks to my MVP lead, Melissa Travers, and my previous MVP lead Rafael Munoz (who isn’t with Microsoft anymore, but I am sure is kicking butt wherever he is). We are truly entering a very very exciting time in the technology space. Both Google and Apple are challenging Microsoft, forcing Microsoft to innovate at a pace like never before. Microsoft is coming out with an incredible amount of good, new and exciting stuff. Windows Mobile 7, Azure, .NET 4.0, Silverlight 4.0, IE9, and of course SharePoint 2010. The level of innovation in the tech industry is simply unprecedented. A truly exciting time for anyone who lives, breathes, sleeps and dreams of technology even when awake! (Like me!) As you know, I’ve been working on my SP2010 book lately. I’m happy to also inform that the book is DONE. WOOHOO!! :). So this means, I’ll have more time to blog, and cause more trouble in general. Once again! THANK YOU! Comment on the article ....

  • How To Remove Hyperlinks from Microsoft Word Documents

    - by Mysticgeek
    Sometimes when you copy text from a webpage and paste it into Word, it can be annoying when the hyperlinks transfer with it. Today we take a look at how to easily remove the hyperlinks if you don’t want them in the document. Here we will cover a few different ways you can remove hyperlinks from emails or webpage data that you enter into a Word document using Paste Special and Keyboard Shortcuts. Remove Hyperlinks in Word Using Paste Special In Word 2010 we copied part of an article from How-To Geek, as you can see the hyperlinks were copied into the document as well. To remove the hyperlinks right-click on the document and you’ll see three icons under Paste Options. We want to select the third one to the right which is Keep Text Only…the text in in the document changes so you can get a preview of how it will look. After selecting Keep Text Only, you can see the hyperlinks have been removed. However, you’ll need to change the fonts and other layouts if you’re not happy with the default of Calibri. In Office 2007 under the Home tab click the dropdown menu under Paste and select Paste Special. In the Paste Special screen select Unformatted Text then click OK. In Office 2003 copy the text into the document, hover your mouse over the clipboard, click the dropdown menu, then select Keep Text Only. Keyboard Ninja Style If you’re a Keyboard Ninja, an easy way to remove all hyperlinks is to use “Ctrl+A” to select everything, then use the key combination “Ctrl+Shift+F9”…We tested this key combination and it works in Word 2003-2010. This will remove all of the hyperlinks and keep the original format of the text. Conclusion There are several different ways to get rid of hyperlinks in text pasted into Word documents. The method you use will depend on your preference and the version of Word you’re using…but the “Ctrl+Shift+F9” keyboard shortcut works in all versions of Word and might be the easiest way. If you always want just text in Word 2007, you can disable automatically disable them. If you have a different method you use to remove hyperlinks from Word documents, leave a comment and let us know!

  • Adding AjaxOnly Filter in ASP.NET Web API

    - by imran_ku07
            Introduction:                     Currently, ASP.NET MVC 4, ASP.NET Web API and ASP.NET Single Page Application are the hottest topics in ASP.NET community. Specifically, lot of developers loving the inclusion of ASP.NET Web API in ASP.NET MVC. ASP.NET Web API makes it very simple to build HTTP RESTful services, which can be easily consumed from desktop/mobile browsers, silverlight/flash applications and many different types of clients. Client side Ajax may be a very important consumer for various service providers. Sometimes, some HTTP service providers may need some(or all) of thier services can only be accessed from Ajax. In this article, I will show you how to implement AjaxOnly filter in ASP.NET Web API application.         Description:                     First of all you need to create a new ASP.NET MVC 4(Web API) application. Then, create a new AjaxOnly.cs file and add the following lines in this file, public class AjaxOnlyAttribute : System.Web.Http.Filters.ActionFilterAttribute { public override void OnActionExecuting(System.Web.Http.Controllers.HttpActionContext actionContext) { var request = actionContext.Request; var headers = request.Headers; if (!headers.Contains("X-Requested-With") || headers.GetValues("X-Requested-With").FirstOrDefault() != "XMLHttpRequest") actionContext.Response = request.CreateResponse(HttpStatusCode.NotFound); } }                     This is an action filter which simply checks X-Requested-With header in request with value XMLHttpRequest. If X-Requested-With header is not presant in request or this header value is not XMLHttpRequest then the filter will return 404(NotFound) response to the client.                      Now just register this filter, [AjaxOnly] public string GET(string input)                     You can also register this filter globally, if your Web API application is only targeted for Ajax consumer.         Summary:                       ASP.NET WEB API provide a framework for building RESTful services. Sometimes, you may need your certain API services can only be accessed from Ajax. In this article, I showed you how to add AjaxOnly action filter in ASP.NET Web API. Hopefully you will enjoy this article too.

  • Getting Current with Visual Studio 2010 for Web Developers

    - by plitwin
    I don't know about you, but I find it kind of crazy at times figuring out if I have the latest of everything there is for the Visual Studio 2010 developer from Microsoft. (This does not include any third-party components, just recommended updates from Microsoft.) And the be honest, the msn.microsoft.com and asp.net sites are not that helpful in figuring this out.In an effort to help, I have enumerated here what the latest VS 2010 setup should include, complete with download links. When you install everything here, you will be able to develop ASP.NET 4.0 Web Forms and ASP.NET MVC 3 applications and web sites in addition to the other stuff your version of Visual Studio supports (e.g., Silverlight, WPF, etc.). These downloads will also include NuGet and the Entity Framework 4.1, so there is no need to download this software separately.Visual Studio 2010. First of all, you need to purchase and install Visual Studio 2010 itself. For the free Express version, you can download it from Visual Web Developer 2010 ExpressVisual Studio Service Pack 1 (released Spring 2011).This is a must-have download that fixes a bunch of bugs and a number of enhancements too including preliminary support for HTML5 and CSS3. See #4 below for better support of these web technologies. Download and install from VS 2010 SP1 download page. You can find details on the features of the service pack here. ASP.NET MVC3 Tools Update (released Spring 2011)If you are using ASP.NET MVC 3, then you should also download install this update for Visual Studio from ASP.NET MVC3 Tools Update download page. This update improves Visual Studio's support for MVC 3, including better scaffolding, NuGet, Entity Framework 4.1, and more. A good overview of the updates can be found in Phil Haack's blog post.Web Standards Update for Microsoft Visual Studio 2010 SP1 (released June 2011)This is an update to VS 2010 SP1 that "brings VS 2010 intellisense & validation as close to W3C specification as we could get via means of an extension". Download and install from Web Standards Update download page. A good description of the changes can be found in the Visual Web Developer Team blog post.Note: I don't control these download pages, so it is possible they will change. If so, I will do my best to update these links. This information was current as of June 24, 2011.

  • The .NET Rocks! Visual Studio 2010 Road Trip

    - by Laila
    Carl Franklin and Richard Campbell, the two .NET Rocks radio show hosts, have decided to set off to 15 cities in the US, between April 19th and May 7th, in their DotNetMobile (a 30 foot RV). What for you'll ask me? Well, to drive around the US, meet up with .NET developers, and show off the latest and greatest in Visual Studio 2010 and .NET 4.0! Each evening, they stop in a city and host a three hour event in front of a 100 to 300 crowd of developers, where Carl is showing off media features in Silverlight 4 and their road trip tracking application, whilst Richard is demo-ing the web performance testing features of VS2010 using his portable server rig. But before they take to the stage, they have a special guest brought in - a rock star from the Visual Studio world - whom they interview for an hour as a .NET Rock episode. So far, they've had - amongst others - Phil Haack, a Program Manager with the ASP.NET team working on ASP.NET MVC, Dan Fernandez, an Evangelism Manager in the Developer and Platform Evangelism team at Microsoft, and Beth Massi, Senior Program Manager on the Visual Studio Community Team at Microsoft. I love the fact that the audience gets a chance to participate, ask questions and have a great laugh, as you can hear in the first episode! Along the way, the .NET Rocks guys are giving away great prizes (including .NET Reflector Pro, ANTS Memory Profiler licenses, and "40" LCD TVs!). Even more out of the ordinary, at each stop on the road trip, one lucky attendee (who entered in the Ride Along competition) gets to jump in the RV with Carl and Richard and ride along with them to the next stop on the roadtrip. How cool is that! Richard told us: "Our first winner in Mountain View was Eric Ziko. I was looking for him to announce that he had won, when he found us and gave us a bottle of scotch he had brought just to say 'thanks for the great show'. We all had a toast from the bottle the next night when he headed back home." Cheeky! There's still space to a few of these events, so if you want to attend, register now, because it's first come first serve. We're grateful to Richard and Carl for giving us the opportunity to sponsor this major .NET event! A unique .NET adventure worth following for sure. Cheers, Laila
