  • Is it safe to Update and/or Insert records into an accounting software's database? (Pastel Evolution)

    - by user1020317
    Our CRM system can post transactions to our accounts software (Pastel Evolution), but it doesn't perform the required currency conversion. Both systems have different "base" currencies (because of our location), so the figure thats sent to Pastel evolution is right, but it is reflected in the wrong currency. The CRM uses an ODBC connection to post figures to Evolution. I can make a tool which sits between the two systems which can update and/or insert the transactions into Pastel, by mimicking what the CRM would have done if it was doing the POST. Is it safe for me to mimic and/or update these transactions directly in the Pastel database? Is it common for important validation to be performed in the ODBC layer, and if so, can I tap into an applications ODBC, or is there a custom driver built by the CRM to communicate with the DB?

  • Apache Rewrite Rules

    - by Philip
    I have moved my website from a Wiki to Wordpress and in the process, realised that I have broken links to some popular pages on my website. Is it possible to fix this with a rewrite rule? I need the rule to redirect anything beginning with "^/wiki/(.+)$" to "/$1" but also replacing the "_" character used in MediaWiki slugs to "-" used in Wordpress slugs. For example: http://example.com/wiki/An_Example_Page should be pointed to: http://example.com/an-example-page Is it possible to write such a rewrite rule? Edit: It appears that Wordpress doesn't even care if the "/wiki/" part is removed - provided the slug matches, and that seems to be case-insensitive too. So all I need to do is change the "_" characters to "-" in the slugs.

  • Is there good FAT driver for FUSE? (Lightweight, not mountlo)

    - by Vi.
    FUSE filesystem list show some FuseFat and FatFuse. Both are old, FatFuse is read-only , FuseFat is non-buildable and probably depends on glib. Now I'm using mountlo for the task (mounting USB drives in generic way without root access or suid things (except of fusermount itself)), but it looks too big for such task. Using FUSE to mount external storage devices is good both for security and for flexibility reason: the kernel sees only block reads and writes while actual code that deals with filesystem details runs with user privileges, allowing user to use custom filesystems and preventing from kernel filesystem exploits. Is there good vfat FUSE driver?

  • How to export or view audio file references in a PDF?

    - by redshift
    I have a an interactive PDF file that is over 90+ pages long. Each page is a map with city names that contains a Spanish pronunciation of that city in a .wav file. I'd say there are about 10-15 audio files for each map which comes out to 1000+ audio files. Is there a way to extract/export a list of the sound file names associated with each map? I tried to save the PDF to an HTML file, but it only exported images and text, and because the audio files were embedded in the PDF, the file names did not carry over to the HTML file. Any other ideas? I need to see what audio file goes with what map/page.

  • How to disable multiple form submit (POST) in IIS

    - by user1209640
    We had a major SharePoint outage a few months back because a user wedged their keyboard in such a way as to cause the Enter button to be pressed indefinitely. The user was on a customized people search page and hundreds of POSTs by the same user were submitted asynchronously, which overloaded the server. Because I work in a large organization, I am looking for a more global way to prevent this from happening. Is there a way to prevent multiple web form submissions by a common user within a short period of time within IIS? I am aware we can write javascript to disable the button after it is clicked, but we are hoping to prevent this issue from occurring on other pages where a similar possibility may exist. Update: It appears looking at the source code, the javascript is performing a document.location = url, whenever keycode 13 (Enter) is pressed. Again, we can write JS to prevent this in this location, but we also want to be able to guard against this kind of issue more generally... preferably at the IIS level.

  • ubuntu 10.04 span window across workspaces

    - by jakerman999
    I'm using an old server machine as a linux box desktop, and as such I have a lot of power but not a lot of display options. I cannot increase my resolution past 800x600 and recently this has become just to small. I have mostly been able to workaround windows being to large for a workspace by moving them with the alt key, but I would like to use something a little more versatile. My plan is to have a setup where I can open a windows (say firefox) on the top-left workspace and then resize it so that it fills four workspaces in an emulated "wall of monitors" fashion. I already have my workspaces arranged like this, but I am not seeing any options for allowing programs/windows to exist on more than one workspace at a time, I know that what I am trying to accomplish is possible (or was at some point in time) because when I google my solution pages appear with people trying to do the opposite (windows already appear on more than one workspace and they dislike it). Any help is much appreciated.

    This isnt a firewall issue, I can telnet to gmail with no problems, but all browsers (chrome, IE, firefox) return a This web page is not available. error when tring to access it through the browser. I can access the same pages, using the same browsers, on the same machine, but through a different user account with no problem. What the hell is going on? Help appreciated. Edit: This is definitely a windows setup issue - I have just created a new admin account and can access https with problems. This is seriously infuriating.

  • Computer won't stay powered up

    - by Android
    I have just tried to turn my PC on this morning and it won't stay powered up. It will come on as normal for about 5 seconds, not quite long enough for the monitor to wake up. Then it will power off. After about 2 seconds it will start again, it will continue like this until I pull out the plug. Plugging it in again doesn't restart the cycle although pressing the power button does. I have tried to clear the cmos but beyond that I have no ideas. It was working perfectly when I put it in hibernate last night. NOTE: I am using a Dell Optiplex 755 UPDATE 1: I took out the motherboard battery and it almost came on then it displays the message Error loading Operating System UPDATE 2: After taking out the custom video card, it says "No hard drive present"

  • Can I capture input text with the P?roblem Steps Recorder on Windows 7?

    - by WindyCityEagle
    I have recently been introduced to the Problem Steps Recorder on Windows 7. It's great. Trouble is, it does not recorder keyboard input. When I look at the output of a recording all I see it User keyboard input in "Untitled - Notepad" [... Backspace Backspace Backspace Backspace Backspace ...] So I know the user typed SOMETHING and then deleted five characters. Is there a way to get the PSR to record what was inputted? Or is that a security issue? This isn't a big deal for notepad, but for custom apps it would be nice to know exactly what a user typed into a text box.

  • [CLOSED] IIS 6 is no longer installed after computer restart.

    - by jarrettcoggin
    [CLOSED] I was doing some maintenance on a build server at work and I changed some various settings (registry settings for custom applications, user permissions, etc.), then I restarted the machine. When the machine came back up, I couldn't access a website that is hosted on this machine, so I went digging around. It seems as if IIS6 was somehow uninstalled, which I know I didn't do. My question is: What would cause this? I've tried to reinstall it, uninstall it, reinstall it again, and nothing has changed. I still have a blank IIS Manager application (inetmgr), and no way to access these websites. BTW, the computer is running Windows Server 2003 R2 x64 Service Pack 2.

  • equivalent to CDN but for dynamical content?

    - by ajsie
    so i know for serving static elements (css, js, images, videos etc) you should use CDN since they are spread out throughout the world. but how could i spread out by apache servers? is there an equivalent to CDN but for dynamical pages? or is it the traditional LAMP way. if so, i guess my best option is to find an international hosting provider that hosts in different countries, so the content will be served from the country located nearest the client machine. any suggestions of such hosting providers? or is it best practice to contact different hosting providers in different countries that do not relate to each other. what is the right way to go?

  • Will a `wireless n` network adapter work `wireless g` router?

    - by ShoeLace1291
    I have verizon fios internet service. I believe they use a Wireless G router, but I just have one question. I currently am using a 54mbps wireless pci adapter in my Windows 7 custom build. It drops the internet connection all the time and is starting to get very irritating. I'm thinking about buying a new one, but all the 300mbps cards on newegg are wireless n. So my question is, will a wireless n network adapter make a difference with a wireless g router?

  • Setting up a reverse proxy [on hold]

    - by mrwooster
    I am looking for the best solution for setting up a very low maintenance reverse proxy for a production website (example.com). The setup is as follows: A blog with will be hosted on heroku, and will reside at example.com/blog A static info page which will be hosted on S3 and will reside at example.com/signup A dynamic content management system, provided and hosted by an external vendor which will respond to requests for any other pages. The two solutions which come to mind are: Use HAProxy Ask the external vendor to reverse proxy requests for /blog and /signup The obvious solution would be to use HAProxy, but, if at all possible, I would like to avoid having to setup and maintain another server (especially such a critical one). I came across a company called Snapt which offers hosted HAProxy solutions, but its more geared towards load-balancing than reverse proxying. Option 2 is a possibility, but gives us very little control over changes and configuration. I see a lot of sites hosting blogs on /blog so this must be fairly common practice, am I missing an obvious solution?

  • XNA: Camera's Rotation and Translation matrices seem to interfere with each other

    - by Danjen
    I've been following the guide here for how to create a custom 2D camera in XNA. It works great, I've implemented it before, but for some reason, the matrix math is throwing me off. public sealed class Camera2D { public Vector2 Origin { get; set; } public Vector2 Position { get; set; } public float Scale { get; set; } public float Rotation { get; set; } } It might be easier to just show you a picture of my problem: http://i.imgur.com/H1l6LEx.png What I want to do is allow the camera to pivot around any given point. Right now, I have the rotations mapped to my shoulder buttons on a gamepad, and if I press them, it should rotate around the point the camera is currently looking at. Then, I use the left stick to move the camera around. The problem is that after it's been rotated, pressing "up" results in it being used relative to the rotation, creating the image above. I understand that matrices have to be applied in a certain order, and that I have to offset the thing to be rotated around the world origin and move it back, but it just won't work! public Matrix GetTransformationMatrix() { Matrix mRotate = Matrix.Identity * Matrix.CreateTranslation(-Origin.X, -Origin.Y, 0.00f) * // Move origin to world center Matrix.CreateRotationZ(MathHelper.ToRadians(Rotation)) * // Apply rotation Matrix.CreateTranslation(+Origin.X, +Origin.Y, 0.00f); // Undo the move operation Matrix mTranslate = Matrix.Identity * Matrix.CreateTranslation(-Position.X, Position.Y, 0.00f); // Apply the actual translation return mRotate * mTranslate; } So to recap, it seems I can have it rotate around an arbitrary point and lose the ability to have "up" move the camera straight up, or I can rotate it around the world origin and have the camera move properly, but not both.

  • Explained: EF 6 and “Could not determine storage version; a valid storage connection or a version hint is required.”

    - by Ken Cox [MVP]
    I have a legacy ASP.NET 3.5 web site that I’ve upgraded to a .NET 4 web application. At the same time, I upgraded to Entity Framework 6. Suddenly one of the pages returned the following error: [ArgumentException: Could not determine storage version; a valid storage connection or a version hint is required.]    System.Data.SqlClient.SqlVersionUtils.GetSqlVersion(String versionHint) +11372412    System.Data.SqlClient.SqlProviderServices.GetDbProviderManifest(String versionHint) +91    System.Data.Common.DbProviderServices.GetProviderManifest(String manifestToken) +92 [ProviderIncompatibleException: The provider did not return a ProviderManifest instance.]    System.Data.Common.DbProviderServices.GetProviderManifest(String manifestToken) +11431433    System.Data.Metadata.Edm.Loader.InitializeProviderManifest(Action`3 addError) +11370982    System.Data.EntityModel.SchemaObjectModel.Schema.HandleAttribute(XmlReader reader) +216 A search of the error message didn’t turn up anything helpful except that someone mentioned that the error messages was bogus in his case. The page in question uses the ASP.NET EntityDataSource control, consumed by a Telerik RadGrid. This is a fabulous combination for putting a huge amount of functionality on a page in a very short time. Unfortunately, the 6.0.1 release of EF6 doesn’t support EntityDataSource. According to the people in charge, support is planned but there’s no timeline for an EntityDataSource build that works with EF6.  I’m not sure what to do in the meantime. Should I back out EF6 or manually wire up the RadGrid? The upshot is that you might want to rethink plans to upgrade to Entity Framework 6 for Web forms projects if they rely on that handy control. It might also help to spend a User voice vote here:  http://data.uservoice.com/forums/72025-entity-framework-feature-suggestions/suggestions/3702890-support-for-asp-net-entitydatasource-and-dynamicda

  • SQL SERVER – Shrinking NDF and MDF Files – Readers’ Opinion

    - by pinaldave
    Previously, I had written a blog post about SQL SERVER – Shrinking NDF and MDF Files – A Safe Operation. After that, I have written the following blog post that talks about the advantage and disadvantage of Shrinking and why one should not be Shrinking a file SQL SERVER – SHRINKFILE and TRUNCATE Log File in SQL Server 2008. On this subject, SQL Server Expert Imran Mohammed left an excellent comment. I just feel that his comment is worth a big article itself. For everybody to read his wonderful explanation, I am posting this blog post here. Thanks Imran! Shrinking Database always creates performance degradation and increases fragmentation in the database. I suggest that you keep that in mind before you start reading the following comment. If you are going to say Shrinking Database is bad and evil, here I am saying it first and loud. Now, the comment of Imran is written while keeping in mind only the process showing how the Shrinking Database Operation works. Imran has already explained his understanding and requests further explanation. I have removed the Best Practices section from Imran’s comments, as there are a few corrections. Comments from Imran - Before I explain to you the concept of Shrink Database, let us understand the concept of Database Files. When we create a new database inside the SQL Server, it is typical that SQl Server creates two physical files in the Operating System: one with .MDF Extension, and another with .LDF Extension. .MDF is called as Primary Data File. .LDF is called as Transactional Log file. If you add one or more data files to a database, the physical file that will be created in the Operating System will have an extension of .NDF, which is called as Secondary Data File; whereas, when you add one or more log files to a database, the physical file that will be created in the Operating System will have the same extension as .LDF. The questions now are, “Why does a new data file have a different extension (.NDF)?”, “Why is it called as a secondary data file?” and, “Why is .MDF file called as a primary data file?” Answers: Note: The following explanation is based on my limited knowledge of SQL Server, so experts please do comment. A data file with a .MDF extension is called a Primary Data File, and the reason behind it is that it contains Database Catalogs. Catalogs mean Meta Data. Meta Data is “Data about Data”. An example for Meta Data includes system objects that store information about other objects, except the data stored by the users. sysobjects stores information about all objects in that database. sysindexes stores information about all indexes and rows of every table in that database. syscolumns stores information about all columns that each table has in that database. sysusers stores how many users that database has. Although Meta Data stores information about other objects, it is not the transactional data that a user enters; rather, it’s a system data about the data. Because Primary Data File (.MDF) contains important information about the database, it is treated as a special file. It is given the name Primary Data file because it contains the Database Catalogs. This file is present in the Primary File Group. You can always create additional objects (Tables, indexes etc.) in the Primary data file (This file is present in the Primary File group), by mentioning that you want to create this object under the Primary File Group. Any additional data file that you add to the database will have only transactional data but no Meta Data, so that’s why it is called as the Secondary Data File. It is given the extension name .NDF so that the user can easily identify whether a specific data file is a Primary Data File or a Secondary Data File(s). There are many advantages of storing data in different files that are under different file groups. You can put your read only in the tables in one file (file group) and read-write tables in another file (file group) and take a backup of only the file group that has read the write data, so that you can avoid taking the backup of a read-only data that cannot be altered. Creating additional files in different physical hard disks also improves I/O performance. A real-time scenario where we use Files could be this one: Let’s say you have created a database called MYDB in the D-Drive which has a 50 GB space. You also have 1 Database File (.MDF) and 1 Log File on D-Drive and suppose that all of that 50 GB space has been used up and you do not have any free space left but you still want to add an additional space to the database. One easy option would be to add one more physical hard disk to the server, add new data file to MYDB database and create this new data file in a new hard disk then move some of the objects from one file to another, and put the file group under which you added new file as default File group, so that any new object that is created gets into the new files, unless specified. Now that we got a basic idea of what data files are, what type of data they store and why they are named the way they are, let’s move on to the next topic, Shrinking. First of all, I disagree with the Microsoft terminology for naming this feature as “Shrinking”. Shrinking, in regular terms, means to reduce the size of a file by means of compressing it. BUT in SQL Server, Shrinking DOES NOT mean compressing. Shrinking in SQL Server means to remove an empty space from database files and release the empty space either to the Operating System or to SQL Server. Let’s examine this through an example. Let’s say you have a database “MYDB” with a size of 50 GB that has a free space of about 20 GB, which means 30GB in the database is filled with data and the 20 GB of space is free in the database because it is not currently utilized by the SQL Server (Database); it is reserved and not yet in use. If you choose to shrink the database and to release an empty space to Operating System, and MIND YOU, you can only shrink the database size to 30 GB (in our example). You cannot shrink the database to a size less than what is filled with data. So, if you have a database that is full and has no empty space in the data file and log file (you don’t have an extra disk space to set Auto growth option ON), YOU CANNOT issue the SHRINK Database/File command, because of two reasons: There is no empty space to be released because the Shrink command does not compress the database; it only removes the empty space from the database files and there is no empty space. Remember, the Shrink command is a logged operation. When we perform the Shrink operation, this information is logged in the log file. If there is no empty space in the log file, SQL Server cannot write to the log file and you cannot shrink a database. Now answering your questions: (1) Q: What are the USEDPAGES & ESTIMATEDPAGES that appear on the Results Pane after using the DBCC SHRINKDATABASE (NorthWind, 10) ? A: According to Books Online (For SQL Server 2000): UsedPages: the number of 8-KB pages currently used by the file. EstimatedPages: the number of 8-KB pages that SQL Server estimates the file could be shrunk down to. Important Note: Before asking any question, make sure you go through Books Online or search on the Google once. The reasons for doing so have many advantages: 1. If someone else already has had this question before, chances that it is already answered are more than 50 %. 2. This reduces your waiting time for the answer. (2) Q: What is the difference between Shrinking the Database using DBCC command like the one above & shrinking it from the Enterprise Manager Console by Right-Clicking the database, going to TASKS & then selecting SHRINK Option, on a SQL Server 2000 environment? A: As far as my knowledge goes, there is no difference, both will work the same way, one advantage of using this command from query analyzer is, your console won’t be freezed. You can do perform your regular activities using Enterprise Manager. (3) Q: What is this .NDF file that is discussed above? I have never heard of it. What is it used for? Is it used by end-users, DBAs or the SERVER/SYSTEM itself? A: .NDF File is a secondary data file. You never heard of it because when database is created, SQL Server creates database by default with only 1 data file (.MDF) and 1 log file (.LDF) or however your model database has been setup, because a model database is a template used every time you create a new database using the CREATE DATABASE Command. Unless you have added an extra data file, you will not see it. This file is used by the SQL Server to store data which are saved by the users. Hope this information helps. I would like to as the experts to please comment if what I understand is not what the Microsoft guys meant.

  • Webby Nominations for Retail

    - by David Dorf
    The Webby Awards were created back in 1996 when the internet was just a baby. This is their 14th year of highlighting excellence on the Web, and there are lots of great nominations. Its quite amazing to see the rich content and interactivity of today's websites. Some interesting nominees for this year are: Sephora did a campaign at Christmas, and what remains of the Sephora Clause website is a bunch of wishes. The Starbucks "All you need is Love" campaign has lots of cool videos. The Sound Check from Walmart highlights raising music artists. Refinery29 has their fashion info hub. The five nominees in the retail category are: Bugaboo.com's website for selling high-end baby strollers. If you're looking for a high-end bag, check out Crumpler's flash-based e-commerce site. It's highly interactive, but a little on the slow side. I Make My Case sells custom designed iPod/iPhone and Blackberry cases. At MOO.com, they love to print. Tons of art for printing customized business cards, post cards, etc. If you want light shoes, check out Puma L.I.F.T. and see just how light shoes can weigh. Check them out, cast a few votes, and see if you're inspired to create something even better.

  • Making Sense of ASP.NET Paths

    - by Rick Strahl
    ASP.Net includes quite a plethora of properties to retrieve path information about the current request, control and application. There's a ton of information available about paths on the Request object, some of it appearing to overlap and some of it buried several levels down, and it can be confusing to find just the right path that you are looking for. To keep things straight I thought it a good idea to summarize the path options along with descriptions and example paths. I wrote a post about this a long time ago in 2004 and I find myself frequently going back to that page to quickly figure out which path I’m looking for in processing the current URL. Apparently a lot of people must be doing the same, because the original post is the second most visited even to this date on this blog to the tune of nearly 500 hits per day. So, I decided to update and expand a bit on the original post with a little more information and clarification based on the original comments. Request Object Paths Available Here's a list of the Path related properties on the Request object (and the Page object). Assume a path like http://www.west-wind.com/webstore/admin/paths.aspx for the paths below where webstore is the name of the virtual. .blackborder td { border-bottom: solid 1px silver; border-left: solid 1px silver; } Request Property Description and Value ApplicationPath Returns the web root-relative logical path to the virtual root of this app. /webstore/ PhysicalApplicationPath Returns local file system path of the virtual root for this app. c:\inetpub\wwwroot\webstore PhysicalPath Returns the local file system path to the current script or path. c:\inetpub\wwwroot\webstore\admin\paths.aspx Path FilePath CurrentExecutionFilePath All of these return the full root relative logical path to the script page including path and scriptname. CurrentExcecutionFilePath will return the ‘current’ request path after a Transfer/Execute call while FilePath will always return the original request’s path. /webstore/admin/paths.aspx AppRelativeCurrentExecutionFilePath Returns an ASP.NET root relative virtual path to the script or path for the current request. If in  a Transfer/Execute call the transferred Path is returned. ~/admin/paths.aspx PathInfo Returns any extra path following the script name. If no extra path is provided returns the root-relative path (returns text in red below). string.Empty if no PathInfo is available. /webstore/admin/paths.aspx/ExtraPathInfo RawUrl Returns the full root relative URL including querystring and extra path as a string. /webstore/admin/paths.aspx?sku=wwhelp40 Url Returns a fully qualified URL including querystring and extra path. Note this is a Uri instance rather than string. http://www.west-wind.com/webstore/admin/paths.aspx?sku=wwhelp40 UrlReferrer The fully qualified URL of the page that sent the request. This is also a Uri instance and this value is null if the page was directly accessed by typing into the address bar or using an HttpClient based Referrer client Http header. http://www.west-wind.com/webstore/default.aspx?Info Control.TemplateSourceDirectory Returns the logical path to the folder of the page, master or user control on which it is called. This is useful if you need to know the path only to a Page or control from within the control. For non-file controls this returns the Page path. /webstore/admin/ As you can see there’s a ton of information available there for each of the three common path formats: Physical Path is an OS type path that points to a path or file on disk. Logical Path is a Web path that is relative to the Web server’s root. It includes the virtual plus the application relative path. ~/ (Root-relative) Path is an ASP.NET specific path that includes ~/ to indicate the virtual root Web path. ASP.NET can convert virtual paths into either logical paths using Control.ResolveUrl(), or physical paths using Server.MapPath(). Root relative paths are useful for specifying portable URLs that don’t rely on relative directory structures and very useful from within control or component code. You should be able to get any necessary format from ASP.NET from just about any path or script using these mechanisms. ~/ Root Relative Paths and ResolveUrl() and ResolveClientUrl() ASP.NET supports root-relative virtual path syntax in most of its URL properties in Web Forms. So you can easily specify a root relative path in a control rather than a location relative path: <asp:Image runat="server" ID="imgHelp" ImageUrl="~/images/help.gif" /> ASP.NET internally resolves this URL by using ResolveUrl("~/images/help.gif") to arrive at the root-relative URL of /webstore/images/help.gif which uses the Request.ApplicationPath as the basepath to replace the ~. By convention any custom Web controls also should use ResolveUrl() on URL properties to provide the same functionality. In your own code you can use Page.ResolveUrl() or Control.ResolveUrl() to accomplish the same thing: string imgPath = this.ResolveUrl("~/images/help.gif"); imgHelp.ImageUrl = imgPath; Unfortunately ResolveUrl() is limited to WebForm pages, so if you’re in an HttpHandler or Module it’s not available. ASP.NET Mvc also has it’s own more generic version of ResolveUrl in Url.Decode: <script src="<%= Url.Content("~/scripts/new.js") %>" type="text/javascript"></script> which is part of the UrlHelper class. In ASP.NET MVC the above sort of syntax is actually even more crucial than in WebForms due to the fact that views are not referencing specific pages but rather are often path based which can lead to various variations on how a particular view is referenced. In a Module or Handler code Control.ResolveUrl() unfortunately is not available which in retrospect seems like an odd design choice – URL resolution really should happen on a Request basis not as part of the Page framework. Luckily you can also rely on the static VirtualPathUtility class: string path = VirtualPathUtility.ToAbsolute("~/admin/paths.aspx"); VirtualPathUtility also many other quite useful methods for dealing with paths and converting between the various kinds of paths supported. One thing to watch out for is that ToAbsolute() will throw an exception if a query string is provided and doesn’t work on fully qualified URLs. I wrote about this topic with a custom solution that works fully qualified URLs and query strings here (check comments for some interesting discussions too). Similar to ResolveUrl() is ResolveClientUrl() which creates a fully qualified HTTP path that includes the protocol and domain name. It’s rare that this full resolution is needed but can be useful in some scenarios. Mapping Virtual Paths to Physical Paths with Server.MapPath() If you need to map root relative or current folder relative URLs to physical URLs or you can use HttpContext.Current.Server.MapPath(). Inside of a Page you can do the following: string physicalPath = Server.MapPath("~/scripts/ww.jquery.js")); MapPath is pretty flexible and it understands both ASP.NET style virtual paths as well as plain relative paths, so the following also works. string physicalPath = Server.MapPath("scripts/silverlight.js"); as well as dot relative syntax: string physicalPath = Server.MapPath("../scripts/jquery.js"); Once you have the physical path you can perform standard System.IO Path and File operations on the file. Remember with physical paths and IO or copy operations you need to make sure you have permissions to access files and folders based on the Web server user account that is active (NETWORK SERVICE, ASPNET typically). Note the Server.MapPath will not map up beyond the virtual root of the application for security reasons. Server and Host Information Between these settings you can get all the information you may need to figure out where you are at and to build new Url if necessary. If you need to build a URL completely from scratch you can get access to information about the server you are accessing: Server Variable Function and Example SERVER_NAME The of the domain or IP Address wwww.west-wind.com or 127.0.0.1 SERVER_PORT The port that the request runs under. 80 SERVER_PORT_SECURE Determines whether https: was used. 0 or 1 APPL_MD_PATH ADSI DirectoryServices path to the virtual root directory. Note that LM typically doesn’t work for ADSI access so you should replace that with LOCALHOST or the machine’s NetBios name. /LM/W3SVC/1/ROOT/webstore Request.Url and Uri Parsing If you still need more control over the current request URL or  you need to create new URLs from an existing one, the current Request.Url Uri property offers a lot of control. Using the Uri class and UriBuilder makes it easy to retrieve parts of a URL and create new URLs based on existing URL. The UriBuilder class is the preferred way to create URLs – much preferable over creating URIs via string concatenation. Uri Property Function Scheme The URL scheme or protocol prefix. http or https Port The port if specifically specified. DnsSafeHost The domain name or local host NetBios machine name www.west-wind.com or rasnote LocalPath The full path of the URL including script name and extra PathInfo. /webstore/admin/paths.aspx Query The query string if any ?id=1 The Uri class itself is great for retrieving Uri parts, but most of the properties are read only if you need to modify a URL in order to change it you can use the UriBuilder class to load up an existing URL and modify it to create a new one. Here are a few common operations I’ve needed to do to get specific URLs: Convert the Request URL to an SSL/HTTPS link For example to take the current request URL and converted  it to a secure URL can be done like this: UriBuilder build = new UriBuilder(Request.Url); build.Scheme = "https"; build.Port = -1; // don't inject port Uri newUri = build.Uri; string newUrl = build.ToString(); Retrieve the fully qualified URL without a QueryString AFAIK, there’s no native routine to retrieve the current request URL without the query string. It’s easy to do with UriBuilder however: UriBuilder builder = newUriBuilder(Request.Url); builder.Query = ""; stringlogicalPathWithoutQuery = builder.ToString(); What else? I took a look through the old post’s comments and addressed as many of the questions and comments that came up in there. With a few small and silly exceptions this update post handles most of these. But I’m sure there are a more things that go in here. What else would be useful to put onto this post so it serves as a nice all in one place to go for path references? If you think of something leave a comment and I’ll try to update the post with it in the future.© Rick Strahl, West Wind Technologies, 2005-2010Posted in ASP.NET

  • How To Restore Firefox Options To Default Without Uninstalling

    - by Gopinath
    Firefox plugins are awesome and they are the pillars for the huge success of Firefox browser. Plugins vary from simple ones like changing color scheme of the browser to powerful ones likes changing the behavior of the browser itself. Recently I installed one of the powerful Firefox plugins and played around to tweak the behavior of the browser. At the end of my half an hour play, Firefox has completely become useless and stopped rending web pages properly. To continue using Firefox I had to restore it to default settings. But I don’t like to uninstall and then install it again as it’s a time consuming process and also I’ll loose all the plugins I’m using. How did I restore the default settings in a single click? Default Settings Restore Through Safe Mode Options It’s very easy to restore default settings of Firefox with the safe mode options. All we need to do is 1.  Close all the Firefox browser windows that are open 2. Launch Firefox in safe mode 3. Choose the option Reset all user preferences to Firefox defaults 4. Click on Make Changes and Restart button. Note: When Firefox restore the default settings, it erases all the stored passwords, browser history and other settings you have done. That’s all. This excellent feature of Firefox saved me from great pain and hope it’s going to help you too. Join us on Facebook to read all our stories right inside your Facebook news feed.

  • Mauritius Software Craftsmanship Community

    There we go! I finally managed to push myself forward and pick up an old, actually too old, idea since I ever arrived here in Mauritius more than six years ago. I'm talking about a community for all kind of ICT connected people. In the past (back in Germany), I used to be involved in various community activities. For example, I was part of the Microsoft Community Leader/Influencer Program (CLIP) in Germany due to an FAQ on Visual FoxPro, actually Active FoxPro Pages (AFP) to be more precise. Then in 2003/2004 I addressed the responsible person of the dFPUG user group in Speyer in order to assist him in organising monthly user group meetings. Well, he handed over management completely, and attended our meetings regularly. Why did it take you so long? Well, I don't want to bother you with the details but short version is that I was too busy on either job (building up new companies) or private life (got married and we have two lovely children, eh 'monsters') or even both. But now is the time where I was starting to look for new fields given the fact that I gained some spare time. My businesses are up and running, the kids are in school, and I am finally in a position where I can commit myself again to community activities. And I love to do that! Why a new user group? Good question... And 'easy' to answer. Since back in 2007 I did my usual research, eh Google searches, to see whether there existing user groups in Mauritius and in which field of interest. And yes, there are! If I recall this correctly, then there are communities for PHP, Drupal, Python (just recently), Oracle, and Linux (which used to be even two). But... either they do not exist anymore, they are dormant, or there is only a low heart-beat, frankly speaking. And yes, I went to meetings of the Linux User Group Meta (Mauritius) back in 2010/2011 and just recently. I really like the setup and the way the LUGM is organised. It's just that I have a slightly different point of view on how a user group or community should organise itself and how to approach future members. Don't get me wrong, I'm not criticizing others doing a very good job, I'm only saying that I'd like to do it differently. The last meeting of the LUGM was awesome; read my feedback about it. Ok, so what's up with 'Mauritius Software Craftsmanship Community' or short: MSCC? As I've already written in my article on 'Communities - The importance of exchange and discussion' I think it is essential in a world of IT to stay 'connected' with a good number of other people in the same field. There is so much dynamic and every day's news that it is almost impossible to keep on track with all of them. The MSCC is going to provide a common platform to exchange experience and share knowledge between each other. You might be a newbie and want to know what to expect working as a software developer, or as a database administrator, or maybe as an IT systems administrator, or you're an experienced geek that loves to share your ideas or solutions that you implemented to solve a specific problem, or you're the business (or HR) guy that is looking for 'fresh' blood to enforce your existing team. Or... you're just interested and you'd like to communicate with like-minded people. Meetup of 26.06.2013 @ L'arabica: Of course there are laptops around. Free WiFi, power outlet, coffee, code and Linux in one go. The MSCC is technology-agnostic and spans an umbrella over any kind of technology. Simply because you can't ignore other technologies anymore in a connected IT world as we have. A front-end developer for iOS applications should have the chance to connect with a Python back-end coder and eventually with a DBA for MySQL or PostgreSQL and exchange their experience. Furthermore, I'm a huge fan of cross-platform development, and it is very pleasant to have pure Web developers - with all that HTML5, CSS3, JavaScript and JS libraries stuff - and passionate C# or Java coders at the same table. This diversity of knowledge can assist and boost your personal situation. And last but not least, there are projects and open positions 'flying' around... People might like to hear others opinion about an employer or get new impulses on how to tackle down an issue at their workspace, etc. This is about community. And that's how I see the MSCC in general - free of any limitations be it by programming language or technology. Having the chance to exchange experience and to discuss certain aspects of technology saves you time and money, and it's a pleasure to enjoy. Compared to dusty books and remote online resources. It's human! Organising meetups (meetings, get-together, gatherings - you name it!) As of writing this article, the MSCC is currently meeting every Wednesday for the weekly 'Code & Coffee' session at various locations (suggestions are welcome!) in Mauritius. This might change in the future eventually but especially at the beginning I think it is very important to create awareness in the Mauritian IT world. Yes, we are here! Come and join us! ;-) The MSCC's main online presence is located at Meetup.com because it allows me to handle the organisation of events and meeting appointments very easily, and any member can have a look who else is involved so that an exchange of contacts is given at any time. In combination with the other entities (G+ Communities, FB Pages or in Groups) I advertise and manage all future activities here: Mauritius Software Craftsmanship Community This is a community for those who care and are proud of what they do. For those developers, regardless how experienced they are, who want to improve and master their craft. This is a community for those who believe that being average is just not good enough. I know, there are not many 'craftsmen' yet but it's a start... Let's see how it looks like by the end of the year. There are free smartphone apps for Android and iOS from Meetup.com that allow you to keep track of meetings and to stay informed on latest updates. And last but not least, there is a Trello workspace to collect and share ideas and provide downloads of slides, etc. Trello is also available as free smartphone app. Sharing is caring! As mentioned, the #MSCC is present in various social media networks in order to cover as many people as possible here in Mauritius. Following is an overview of the current networks: Twitter - Latest updates and quickies Google+ - Community channel Facebook - Community Page LinkedIn - Community Group Trello - Collaboration workspace to share and develop ideas Hopefully, this covers the majority of computer-related people in Mauritius. Please spread the word about the #MSCC between your colleagues, your friends and other interested 'geeks'. Your future looks bright Running and participating in a user group or any kind of community usually provides quite a number of advantages for anyone. On the one side it is very joyful for me to organise appointments and get in touch with people that might be interested to present a little demo of their projects or their recent problems they had to tackle down, and on the other side there are lots of companies that have various support programs or sponsorships especially tailored for user groups. At the moment, I already have a couple of gimmicks that I would like to hand out in small contests or raffles during one of the upcoming meetings, and as said, companies provide all kind of goodies, books free of charge, or sometimes even licenses for communities. Meeting other software developers or IT guys also opens up your point of view on the local market and there might be interesting projects or job offers available, too. A community like the Mauritius Software Craftsmanship Community is great for freelancers, self-employed, students and of course employees. Meetings will be organised on a regular basis, and I'm open to all kind of suggestions from you. Please leave a comment here in blog or join the conversations in the above mentioned social networks. Let's get this community up and running, my fellow Mauritians! Recent updates The MSCC is now officially participating in the O'Reilly UK User Group programm and we are allowed to request review or recension copies of recent titles. Additionally, we have a discount code for any books or ebooks that you might like to order on shop.oreilly.com. More applications for user group sponsorship programms are pending and I'm looking forward to a couple of announcement very soon. And... we need some kind of 'corporate identity' - Over at the MSCC website there is a call for action (or better said a contest with prizes) to create a unique design for the MSCC. This would include a decent colour palette, a logo, graphical banners for Meetup, Google+, Facebook, LinkedIn, etc. and of course badges for our craftsmen to add to their personal blogs and websites. Please spread the word and contribute. Thanks!
