  • Where do we put "asking the world" code when we separate computation from side effects?

    - by Alexey
    According to Command-Query Separation principle, as well as Thinking in Data and DDD with Clojure presentations one should separate side effects (modifying the world) from computations and decisions, so that it would be easier to understand and test both parts. This leaves an unanswered question: where relatively to the boundary should we put "asking the world"? On the one hand, requesting data from external systems (like database, extental services' APIs etc) is not referentially transparent and thus should not sit together with pure computational and decision making code. On the other hand, it's problematic, or maybe impossible to tease them apart from computational part and pass it as an argument as because we may not know in advance which data we may need to request.

  • SQL Server Management Studio not scripting all objects

    - by Ian Boyd
    i've been attempting to script a database using SQL Server 2005 Management Studio. i cannot get it to script some objects. It scripts others, but skips some. i can provide detailed screen shots the options being selected including all tables the folder where the script files will go the folder being empty before scripting the scripting process saying Sucess when scripting a table the destination folder no longer empty, with a hundred or so script files the script of some tables not being in the folder. And earlier SSMS would not script some views. Is this a known thing that the the Generate Scripts task does not generate scripts? Update Known issue on Microsoft Connect, but Microsoft couldn't repro the steps, so they closed closed the ticket. Fails on SQL Server 2005, also fails on SQL Server 2008. Update Two Some basic questions: 1.What version of SQL Server? Microsoft SQL Server 2000 - 8.00.194 (Intel X86) Microsoft SQL Server 2005 - 9.00.3042.00 (Intel X86) Microsoft SQL Server 2008 - 10.0.2531.0 (Intel X86) Microsoft SQL Server 2005 Management Studio: 9.00.4035.00 Microsoft SQL Server 2008 Management Studio: 10.0.1600.22 2.What O/S are you running on? Windows Server 2000 Windows Server 2003 Windows Server 2008 3.How are you logging in to SQL server? sa/password Trusted authentication 4.Have you verified your account has full access to all objects? Yes, i have access to all objects. 5.Can you use the objects that fail to script? (eg: select top(10) * from nonScriptingTable) Yes, all objects work fine. SQL Server Enterprise Manager can script the objects fine. Update Three They fail no matter what version of SQL Server you script against. It wasn't a problem in Enterprise Manager: Client Tools SQL Server 2000 SQL Server 2005 SQL Server 2008 ============ =============== =============== =============== 2000 Yes n/a n/a 2005 No No No 2008 No No No Update Four No errors found in the database using: DBCC CHECKDB go DBCC CHECKCONSTRAINTS go DBCC CHECKFILEGROUP go DBCC CHECKIDENT go DBCC CHECKCATALOG go EXECUTE sp_msforeachtable 'DBCC CHECKTABLE (''?'')' Honk if you hate SSMS.

  • Connect over WiFi to SQL Server from another computer

    - by Bronzato
    I tried to connect over WiFi to SQL Server with SQL Server Management Studio from another computer, but it failed. I have a computer with Windows 7 & SQL Server 2008 (lets say the server computer). Next to it I have a freshly installed computer with Windows 7 & SQL Server Management Studio (let's say the client computer). What I did on the server computer: Configure firewall by enabling port 1433 Enabled network protocols (TCP/IP) inside SQL Server Configuration Manager Checked Allow remote connections to this server in server properties in the SQL Server Management application. Started SQL Server Browser Restarted services (SQL Server Browser is stopped at this point, but I don't think it is necessary. Is it?) Next, I successfully tested a ping on the port 1433 from my client computer with a tool named tcping (ex: tcping 192.168.1.4 1433). But I still cannot connect from my client computer to SQL Server on my server computer. Ok, something new with this problem: Until now, I successfully connected to my "server computer" with Management Studio. What I did is type the computer name in the server name field in the connection window of Management Studio. My previous (failed) attempt was to type the computer name followed by the instance of SQL server (ex: COMPUTER_NAME\SQL2008). I don't know why I only have to type the computer name. Now my new challenge is to be successful in connecting my VB6 application to this remote database located on my "server computer". I have a connection string for this but it failed to connect. Here is my connection string: "Provider=SQLOLEDB.1;Password=mypassword;User ID=sa;Initial Catalog=TPB;Data Source=THIERRY-HP\SQL2008" Any idea what's going wrong?

  • Is client side JavaScript capable of ~replicating the Node.JS module loading system?

    - by jt0dd
    I like the Node.JS style of JavaScript, where I can write all of my functionalities into smaller files and then require those neatly from within my code. I'm even thinking about trying to write a framework to mimic that behavior in client-side JS. My goal would be to implement the module loading system as accurately as possible - See Module docs. For require(), I can use things detailed in answers to this question, most notably JQuery's $.getScript(). It seems to me that other aspects of the module loading system should be possible as well. So I'm asking more experienced programmers here first, before I waist my time: Is there something that I'm missing that's going to cause such an attempt to fail miserably, or can this be successfully done?

  • How do I restore a database on a remote SQL server 2005 from a local backup?

    - by MatsT
    I have been given access to (parts of) a remote SQL Server 2005 with SQL Server authentication in order to be able to make changes to a database without involving other people who is not working on the project. The database have been created on my local machine. Is there any way to restore the remote database from a backup file on my local computer? I do not currently have access to the filesystem on the remote server. EDIT: To clarify, the access I have is that i can log in to the server via the SQL Server Management Studio. I have one connection to my local database server and one connection to the remote server. What I basically want to do is copy the database from one connection to the other.

  • How can I refactor client side functionality to create a product line-like generic design?

    - by Nupul
    Assume the following situation similar to that of Stack Overflow: I have a system with a front-end that can perform various manipulations on the data (by sending messages to REST back-end): Posting Editing and deleting Adding labels and tags Now in the first version we created it well modularized but the need as of now for 'evolving' the system similar to Stack Overflow. My question is how best to separate the commonality and how to incorporate the variability with respect to the following: Commonality: The above 'functionalities' and sending/receiving the data from the server Look and feel (also a variability as explained below) HTTP verbs associated with the above actions Variability: The RESTful URLs where the requests are sent The text/style of the UI (the commonality is analogous to Stack Overflow - the functionality of upvotes, posting a question remains the same, but the words, the icons, the look and feel is still different across sites) I think this is entirely a client-side code organization/refactoring issue. I'm heavily using jQuery, javascript and backbone for front-end development. My question is how best should I isolate the same to be able to create multiple such aspects to the tool we are currently working on?

  • SQL Server Management Studio Connect to Server List Editing

    - by Paul Farry
    I'm using SQLServer Management Studio (2005) and I have a fairly lengthy list of servers in there, and I'd like to get rid of some of them that are no longer in use, without having to set them all up again. I know that the C:\Users\*\AppData\Roaming\Microsoft\Microsoft SQL Server\90\Tools\Shell\mru.dat can be deleted and this will remove ALL the entries, but is there anyway to just delete some of them? (Coding info) I looked at the file and it is a serialised blob from the Microsoft.SqlServer.Express.ConnectionDlg.dll (Class Personalization) in the Appplication directory, but all the methods are private. So I can't just create an instance of this and then call Remove on the entries. Update I have written an Article on CodeProject explaining How this can be achieved. http://www.codeproject.com/KB/vb/AlterSQL2005MRU.aspx

  • Transferring DHCP using Windows Server Migration Tool - Why is Powershell is crashing on the import of the .mig file?

    - by Mike
    I am migrating DHCP from a windows server 2003R2 DC to a Windows Server 2008R2 DC I've followed this video and its predecessor (Installing Windows Server Migration Tools) http://technet.microsoft.com/en-us/video/migrating-dhcp-using-the-windows-server-2008-r2-migration-tools.aspx I went through everything smoothly until the last step. I have exported a .mig file with my DHCP configuration on the old 2003r2 server. I transferred this .mig file over to my 2008R2 server, when running the import command, it will appear to work for a minute or two and then I get a generic windows "Powershell has stopped working" error and I have to close the program. Under the problem details I see the following: FileVersionOfSystemManagementAutomation: 6.1.7600.16385 InnermostExceptionType: System.AccessViolationException OutermostExceptionType: System.AccessViolationException DeepestPowerShellFrame: unknown OS Version: 6.1.7600.2.0.0.272.7 LocaleID: 1033 Seems like there are permissions issues maybe? I am running powershell as an admin and am logged in to the server as a domain administrator. Any Ideas? Thanks

  • How to use symbolic links in windows server 2008R2 across the network (mklink)

    - by server info
    I have One Server (Srv1) which holds data with file shares and the storage is full. Now I have second Server (Srv2) which has alot more space. No I would like to transfer all the data von Serv1 to Serv2 and have links to the new destination. I found mklink very useful here but unfortunately it does not work over the network. Which also points the docu out. People heavily rely on the path's so it would be helpful if somone has a pointer for me... how to handle symbolic links a cross the network with Windows Servers. I am running Windows Server 2008. Thanks for any help

  • Are there any adverse side effects to loading html5shiv in every browser?

    - by Jeff
    On the html5shiv Google Code page the example usage includes an IE conditional: <!--[if lt IE 9]> <script src="dist/html5shiv.js"></script> <![endif]--> However on the html5shiv github page, the description explains: This script is the defacto way to enable use of HTML5 sectioning elements in legacy Internet Explorer, as well as default HTML5 styling in Internet Explorer 6 - 9, Safari 4.x (and iPhone 3.x), and Firefox 3.x. An obvious contradiction. So to satisfy my curiosity, for anyone who has studied the code, are there any adverse side affects to loading html5shiv in every browser (without the IE conditional)? EDIT: My goal, obviously, is to use the shiv without the IE conditional.

  • How to redirect keeping the referral without server-side redirects?

    - by sergilazaro
    I have an HTML page hosted in Dropbox that some external websites link to. I want to redirect to a different page using only HTML or Javascript, since I can't use any server-side redirects. My goal is to be able to keep the original referral information for analytics. I've tried different ways but they all end up showing up with no referral. So if a blog that I have no control over (B) links to my public static page on Dropbox (D), and I want a redirect to the new page hosted elsewhere (N), I would like for the analytics for N to be shown as B, not D. Is that even possible?

  • Install SQL Server 2000 on virtual machine Windows Server 2008 (HyperV)

    - by podosta
    Hi, My hierarchy ask me to setup a production Windows server 2008 virtual machine (HyperV) with SQL 2000 Standard Ed. installed on it. I can't find on the net much information about the relative "compatibility" of SQL2000 on WinSrv2008. Of course I found some obscure answers like : "it's impossible, it's not supported, don't do it". I already setup the machine, it's working, but... I don't know where I'm going. Do you experienced this kind of configuration ? Could you give me some advices ? Could you tell me the pros and cons ? Thanks a lot for you help

  • What advantages are conferred by using server-side page rendering?

    - by user1303881
    I am developing a web app and I have currently written the entire website in html/js/css and on the backend I have servlets that host some RESTFUL services. All the presentation logic is done through getting json objects and modifying the view through javascript. The application is essentially a search engine, but it will have user accounts with different roles. I've been researching some frameworks such as Play and Spring. I'm fairly new to web development, so I was wondering what advantages using server side page rendering would provide? Is it: Speed? Easier development and workflow? Access to existing libraries? More? All of the above?

  • How to clear browser's cache from server side?

    - by Dunith Dhanushka
    I have to create a web application that deals with user's sensitive information. I need to immediately clear the browser's cache after user logs out since cached data would be vulnerable. Client's browser should be enforced to clear the Cache from server side. Also all cache policies must be exposed to the client from the server side. Is there any solution to this problem?
