  • how to join tables sql server

    - by Rick
    Im having some trouble with joining two tables. This is what my two tables look like: Table 1 Customer_ID CustomerName Add. 1000 John Smith 1001 Mike Coles 1002 Sam Carter Table 2 Sensor_ID Location Temp CustIDFK 1000 NY 70 1002 NY 70 1000 ... ... 1001 1001 1002 Desired: Sensor_ID Location Temp CustIDFK 1000 NY 70 John Smith 1002 NY 70 Sam Carter 1000 ... ... John Smith 1001 Mike Coles 1001 1002 I have made Customer_ID from table 1 my primary key, created custIDFK in table 2 and set that as my foreign key. I am really new to sql server so I am still having trouble with the whole relationship piece of it. My goal is to match one customer_ID with one Sensor_ID. The problem is that the table 2 does not have "unique IDs" since they repeat so I cant set that to my foreign key. I know I will have to do either an inner join or outer join, I just dont know how to link the sensor id with customer one. I was thinking of giving my sensor_ID a unique ID but the data that is being inserted into table 2 is coming from another program. Any suggestions?

  • What is the best way to deserialize generics written with a different version of a signed assembly?

    - by Rick Minerich
    In other cases it has been suggested that you simply add a SerializationBinder which removes the version from the assembly type. However, when using generic collections of a type found in a signed assembly, that type is strictly versioned based on its assembly. Here is what I've found works. internal class WeaklyNamedAssemblyBinder : SerializationBinder { public override Type BindToType(string assemblyName, string typeName) { ResolveEventHandler handler = new ResolveEventHandler(CurrentDomain_AssemblyResolve); AppDomain.CurrentDomain.AssemblyResolve += handler; Type returnedType; try { AssemblyName asmName = new AssemblyName(assemblyName); var assembly = Assembly.Load(asmName); returnedType = assembly.GetType(typeName); } catch { returnedType = null; } finally { AppDomain.CurrentDomain.AssemblyResolve -= handler; } return returnedType; } Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args) { string truncatedAssemblyName = args.Name.Split(',')[0]; Assembly assembly = Assembly.Load(truncatedAssemblyName); return assembly; } } However, causing the binding process to change globally seems rather dangerous to me. Strange things could happen if serialization was happening in multiple threads. Perhaps a better solution is to do some regex manipulation of the typeName? What do you think?

  • Python Macros: Use Cases?

    - by Rick Copeland
    If Python had a macro facility similar to Lisp/Scheme (something like MetaPython), how would you use it? If you are a Lisp/Scheme programmer, what sorts of things do you use macros for (other than things that have a clear syntactic parallel in Python such as a while loop)?

  • Cruise Control.net Ms Build Task setting XML output Name

    - by Eric Brown - Cal
    We are running version 1.5.6755.1 of CruiseControl.net. Here is our block that executes a build <!-- MSBuild of Source Code --> <cb:define name="BuildOneProject-block"> <msbuild> <executable>C:\WINDOWS\Microsoft.NET\Framework\v3.5\MSBuild.exe</executable> <!-- Directory where source is --> <workingDirectory>D:\CC\$(AppName)\Source</workingDirectory> <!-- Solution file to be built--> <projectFile>D:\CC\$(AppName)\Source\$(ProjectName)\$(ProjectName).csproj</projectFile> <buildArgs>/noconsolelogger /p:SolutionName=\$(AppName) /p:SolutionDir=D:\CC\$(AppName)\Source /p:Configuration=$(ReleaseOrDebug) /v:diag</buildArgs> <targets>Build</targets> <timeout>900</timeout> <logger>C:\Program Files\CruiseControl.NET\server\ThoughtWorks.CruiseControl.MsBuild.dll</logger> </msbuild> </cb:define> When this run it generates a file with a name like.. msbuild-results-5cb1c8fa-1bba-4e97-a0b1-b2bf637308dc.xml Is there another tag on the MsBuild task that allows me to name the xml file? Is there an argument to the Logger that allows me to specify the name of the xml file?

  • Codeigniter: Checklist for new users & logistics of app

    - by Kevin Brown
    I'm developing my first web-app, and I'm working through logistics. New users (At first login) need to complete a few things before they can use the app fully. For example, they need to complete their profile before they can move on to step 2, which is taking a test. What's the best way to go about creating a "new-user" checklist? I want it to be as simple as possible, coding wise, and as easy as possible for the user.

  • Legality, terms of service for performing a web crawl

    - by Berlin Brown
    I was going to crawl a site for some research I was collecting. But, apparently the terms of service is quite clear on the topic. Is it illegal to now "follow" the terms of service. And what can the site normally do? Here is an example clause in the TOS. Also, what about sites that don't provide this particular clause. Restrictions: "use any robot, spider, site search application, or other automated device, process or means to access, retrieve, scrape, or index the site" It is just research? Edit: "OK, from the standpoint of designing an efficient crawler. Should I provide some form of natural language engine to read terms of service and then abide by them."

  • Asp.Net Login Control very slow initial connection to Non-Trusted AD Domain

    - by Eric Brown - Cal
    ASP.NET Login control is very slow making the initial connection to AD when authenticating to a different domain than the domain the web server is a member of. Problem occurs for the IIS server and when using with the Visual Studio's built in web server. It takes about 30 seconds the first time when attempting to use the control to connect against another domain. There is no trust relationship bewteen the web server's domain and the other domains (attempted connecting to several different domains). Subsequent connections execute quickly until the connection times out. Using Systernals Process Monitor to troubleshoot, there are two OpenQuery operations right before the delay to "C:\WINDOWS\asembly\GAC_MSIL\System.DirectoryServices\2.0.0.0_b03f5f7f11d50a3a\Netapi32.dll with a result NAME NOT FOUND" and right after the 30 second delay the TCP Send and TCP Recieves indicate communication begins with the AD server. Things we have tried: Impersonating an administrator on the web server in the web.config; Granting permissions to the CryptoKeys to the NetworkService and ASPNET; Specifying by IP instead of DNS name; Multiple variations of specifying the name and ldap server with domains and OU's; Local host entries; Looked for ports being blocked (SYN_SENT) with netstat -an. Nslookup resolves all the domains and systems involved correectly. TraceRt shows the Correct routes Any Idea or hints are greately appreicated.

  • Draw text on a loaded pdf file with Zend Framework

    - by Rick de Graaf
    Hello, I'm trying to load a existing pdf file, and fill this with database information. Loading the file and everything is working, except for writing data to the loaded page. It doesn't write text to the loaded page. If I add a new page en use a foreach to apply drawing to all pages, all added pages are written, except for the loaded one. Below is the code I'm using: $pdf = Zend_Pdf::load('./documents/agreements/_root/gegevens.pdf'); // Load pdf $pdf->pages = array_reverse($pdf->pages); // reverse pages $pdf->pages[] = new Zend_Pdf_Page(Zend_Pdf_Page::SIZE_A4); // Add a page (A4) $font = Zend_Pdf_Font::fontWithName(Zend_Pdf_Font::FONT_HELVETICA); // Set font foreach($pdf->pages as $page) // Apply settings+text to every page (total of 2) { $page->setFont($font, 36); $page->setAlpha(0.25); $page->drawText('LALALALALALALA', 62, 260, 'UTF-8'); } $pdf->save('./documents/agreements/Gegevens_'.$this->school_id.'.pdf'); // Save file

  • Should an installer run automatically with a setup project

    - by Tom Brown
    I have a windows app (app.exe) build with visual studio 2008, for which I have created a custom installer class. When I run installutil.exe on app.exe, the custom installer is executed OK. I then added a setup & deployment project to create the windows installer file app.msi - this works fine but it does not run the custom installer. How is my custom installer class supposed to get linked to the setup MSI file?

  • Codeigniter: Submitting Forms

    - by Kevin Brown
    How do I submit a form that can do two different things based on the URI? For example, if the URI contains a string "new" the form will submit differently than it would if "new" were not in the URI. I'm having trouble implementing this, as when a form is submitted, it takes the URI of whatever "form_open" says.

  • How to access Active Directory using C++Builder?

    - by Gus Brown
    I need to get a list of user names from Active Directory using C++Builder. I know I could shell out to batch file and run the csvde.exe command but surely there is a nicer way using a library or something, right? Are there any C++ libraries? (hopefully with examples?) Many thanks! -Dan

  • Where is the visual studio 2010 setup and deployment project template

    - by Tom Brown
    In VS 2008, when I create a project I can add a setup project easily. File-Add-New Project... then in Project types: select Other Project Types-Setup and Deployment - and there are a whole load of installed templates - including Setup Project to create an MSI installer. But in VS 2010 - there are no templates in the Setup and Deployment - I'm using the Pro edition, not Express or beta: Is this the same for you - or do I have a duff installation of VS 2010? Otherwise how do I create an MSI installer for my projects?

  • Codeigniter: db data in controller

    - by Kevin Brown
    I'm confused about what to do... I'm working on a user's page where they can view certain things only if their supervisor has given them "money" or "credits". I need a simple way to get the person that is their supervisor by doing something like: $data['employer'] = $this->home_model->getEmployees(array('user_id'=>$manager_id)); Basically, get the user information about a person who's user_id matches the manager_id of the currently logged in member. I don't know how to set the variable $manager_id. Additional Information: The current user has an id, and a manager_id. I need the id of the manager. So, I need to grab the manager_id of the logged-in user and find the manager who's user_id is that of the manager_id. What's the process to do this? I can get each individually, but I don't know how to use one to get the other... I know it is confusing, but I'm confused! Thanks for the help!

  • Yet another Haskell vs. Scala question

    - by Travis Brown
    I've been using Haskell for several months, and I love it—it's gradually become my tool of choice for everything from one-off file renaming scripts to larger XML processing programs. I'm definitely still a beginner, but I'm starting to feel comfortable with the language and the basics of the theory behind it. I'm a lowly graduate student in the humanities, so I'm not under a lot of institutional or administrative pressure to use specific tools for my work. It would be convenient for me in many ways, however, to switch to Scala (or Clojure). Most of the NLP and machine learning libraries that I work with on a daily basis (and that I've written in the past) are Java-based, and the primary project I'm working for uses a Java application server. I've been mostly disappointed by my initial interactions with Scala. Many aspects of the syntax (partial application, for example) still feel clunky to me compared to Haskell, and I miss libraries like Parsec and HXT and QuickCheck. I'm familiar with the advantages of the JVM platform, so practical questions like this one don't really help me. What I'm looking for is a motivational argument for moving to Scala. What does it do (that Haskell doesn't) that's really cool? What makes it fun or challenging or life-changing? Why should I get excited about writing it?

  • How do I maintain scroll position in MVC?

    - by Eric Brown
    Im working on a project in MVC and have enjoyed learning about it. There are a few growing pains but once you figure them out it's not bad. One thing that is really simple in the WebForms world is maintaining the scroll position on a page. All you do is set the MaintainScrollPositionOnPostback property to true. However, in MVC, Im not using postbacks so this will not work for me. What is the standard way of handling this? Edit: Ajax is acceptable, but I was also wondering how you would do it without AJAX.

  • Class inheritance in PHP 5.2: Overriding static variable in extension class?

    - by Christoffer
    Hi, I need to bea be able to use a static variable set in a class that extends a base class... from the base class. Consider this: class Animal { public static $color = 'black'; public static function get_color() { return self::$color; } } class Dog { public static $color = 'brown'; } echo Animal::get_color(); // prints 'black' echo Dog::get_color(); // also prints 'black' This works wonderfully in PHP 5.3.x (Dog::get_color() prints 'brown') since it has late static binding. But my production server runs PHP 5.2.11 and so I need to adapt my script. Is there a somewhat pretty workaround to solve this issue? Cheers! Christoffer

  • User Management: Managing users in user-defined "groups", database schema and logistics

    - by Kevin Brown
    I'm a noob, development wise and logistically-wise. I'm developing a site that lets people take a test... My client wants the ability for a user with the roll/privledge "admin" (a step below a super-admin) to be allowed to create users and only see/edit the users that they create... The users created in that "category" or group need some information that their superior provides. For example, I log in as a "manager", I have the ability to invite people to take the test, and manage those people. Before adding those people, I will have filled out a short survey about myself... Right now, the users that are invited will be asked some of the same questions as the manager. I'd like to cut down the redundancy by using the information put into the database by the manager and apply it to the invited users. How do I set up my database to work with this criterion? I'm a little confused about how to do this! Let me know if I can add more details... (This is a mysql and php app)

  • Zipping with padding in Haskell

    - by Travis Brown
    A couple of times I've found myself wanting a zip in Haskell that adds padding to the shorter list instead of truncating the longer one. This is easy enough to write. (Monoid works for me here, but you could also just pass in the elements that you want to use for padding.) zipPad :: (Monoid a, Monoid b) => [a] -> [b] -> [(a, b)] zipPad xs [] = zip xs (repeat mempty) zipPad [] ys = zip (repeat mempty) ys zipPad (x:xs) (y:ys) = (x, y) : zipPad xs ys This approach gets ugly when trying to define zipPad3. I typed up the following and then realized that of course it doesn't work: zipPad3 :: (Monoid a, Monoid b, Monoid c) => [a] -> [b] -> [c] -> [(a, b, c)] zipPad3 xs [] [] = zip3 xs (repeat mempty) (repeat mempty) zipPad3 [] ys [] = zip3 (repeat mempty) ys (repeat mempty) zipPad3 [] [] zs = zip3 (repeat mempty) (repeat mempty) zs zipPad3 xs ys [] = zip3 xs ys (repeat mempty) zipPad3 xs [] zs = zip3 xs (repeat mempty) zs zipPad3 [] ys zs = zip3 (repeat mempty) ys zs zipPad3 (x:xs) (y:ys) (z:zs) = (x, y, z) : zipPad3 xs ys zs At this point I cheated and just used length to pick the longest list and pad the others. Am I overlooking a more elegant way to do this, or is something like zipPad3 already defined somewhere?
