  • Multiple View application and Navigation Bar

    - by byronh
    Hi. I'm working in a iphone view-based application. The application works this way: First view is a welcome view with buttons for load other views. Second view is a map that shows the location using gps. Third view is a search engine that loads some information to show on the map and on a list (This has two button to load map or table). Fourth view is a table view that shows the results and then loads the detail on another view and load a web site on another view. My problem is with this view, because i don't know how can implement a navigation bar in this view that loads the detail and the web view. Thanks for your help. Byron H.

  • Validating XML with multiple XSDs in Java

    - by Arian
    Hello! I want to parse an XML file with Java and validate it in the same step against an XSD schema. An XML file may contain content of several schemas, like this: <outer xmlns="my.outer.namespace" xmlns:x="my.third.namespace"> <foo>hello</foo> <inner xmlns="my.inner.namespace"> <bar x:id="bar">world</bar> </inner> </outer> Given a namespace the corresponding xsd file can be provided, but the used namespaces are unknown before parsing. If a schema defines default values for attributes, I also want to know that somehow. I was able to validate a file if the schemas are known, I was able to parse a file without validation and I implemented a LSResourceResolver. However, I can't get all of it working together. How do I have to set up my (SAX) parser?

  • Using a singleton database class in functions and multiple scripts(PHP) - best use methods

    - by dscher
    I have a singleton db connection which I get with: $dbConnect = myDatabase::getInstance(); which is easy enough. My question is what is the least rhetorical and legitimate way of using this connection in functions and classes? It seems silly to have to declare the variable global, pass it into every single function, and/or recreate this variable within every function. Is there another answer for this? Obviously I'm a noob and I can work my way around this problem 10 different ways, none of which is really attractive to me. It would be a lot easier if I could have that $dbConnect variable accessible in any function without needing to declare it global or pass it in. I do know I can add the variable to the $_SERVER array...is there something wrong with doing this? It seems somewhat inappropriate to me. Another quick question: Is it bad practice to do this: $result = myDatabase::getInstance()-query($query); from directly within a function?

    - by ranzy
    Is there way to use more than 1 layout manager in Java. Right now I'm using a gridLayout to implement a chess board but beneath it I would like to put some other stuff but not in a gridLayout. Maybe a FlowLayout or some other layout. How would I go about doing this? Thanks!

  • Thoughts on streamlining multiple .Net apps

    - by John Virgolino
    We have a series of ASP.Net applications that have been written over the course of 8 years. Mostly in the first 3-4 years. They have been running quite well with little maintenance, but new functionality is being requested and we are running into IDE and platform issues. The apps were written in .Net 1.x and 2.x and run in separate spaces but are presented as a single suite of applications which use a common navigation toolbar (implemented as a user control). Every time we want to add something to a menu in the nav we have to modify it in all the apps which is a pain. Also, the various versions of Crystal reports and that we used tables to organize the visual elements and we end up with a mess, especially with all the multi-platform .Net versions running. We need to streamline the suite of apps and make it easier to add on new apps without a hassle. We also need to bring all these apps under one .Net platform and IDE. In addition, there is a WordPress blog styled to match the style of the application suite "integrated" into the UI and a link to a MediaWiki Wiki application as well. My current thinking is to use an open source content management system (CMS) like Joomla (PHP based unfortunately, but it works well) as the user interface framework for style templating and menu management. Joomla's article management would allow us to migrate the Wiki content into articles which could be published without interfering with the .Net apps. Then essentially use an IFrame within an "article" to "host" the .Net application, then... Upgrade the .Net apps to VS2010, strip out all the common header/footer controls and migrate the styles to use the style sheets used in the CMS. As I write this, I certainly realize this is a lot of work and there are optimization issues which this may cause as well as using IFrames seems a bit like cheating and I've read about issues with IFrames. I know that we could use .Net application styling, but it seems like a lot more work (not sure really). Also, the use of a CMS to handle the blog and wiki also seems appealing, unless there is a .Net CMS out there that can handle all of these requirements. Given this information, I am looking to know if I am totally going in the wrong direction? We tried to use open source and integrate it over time, but not this has become hard to maintain. Am I not aware of some technology out there that will meet our requirements? Did we do this right and should we just focus on getting the .Net streamlined? I understand that no matter what we do, it's going to be a lot of work. The communities considerable experience would be helpful. Thanks!! PS - A complete rewrite is not an option.

  • Using multiple databases within one application

    - by Alex
    I have a web application made for several groups of people not connected with each other. Instead of using one database for all of them, I'm thinking about making separate databases. This will improve the speed of the queries and make me free from checking to what group the user belongs. But since I'm working with LINQ to SQL, my classes are explicitly connected with the databases, so I will have to make separate DataContexts for all of the databases. So how can I solve this problem? Or should I just not bother and use one database only?

  • Using combo boxes with a binding source and multiple tables

    - by Scott Chamberlain
    I have two data tables in a data set for example lets say Servers: | Server | Ip | Users: | Username | Password | ServerToConnectTo | and there is a foreign key on users that points to servers. How do I make a combo box that list all of the servers. Then how do I make the selected server in that combo box be saved in the data set in the ServerToConnect to column.

  • One repository/multiple projects without getting mixed up?

    - by OverTheRainbow
    Hello After reading Joel's last article on Mercurial, I'm giving it a shot on XP as a single-user, single-computer source control system. One thing I'd like to check, though, is: It'd be easier to just create a repository of all the tiny projects I keep in eg. C:\VB.Net\, but the result is that the changes I make to the different projects therein (C:\VB.Net\ProjectA\, C:\VB.Net\ProjectB\, etc.) will be mixed in a single changelog. But if I use a single repository for all projects, when I do diff's or go through the change history, will I be able to filter data so that I only see changes pertaining to a given project? Otherwise, is creating repositories in each project directory the only solution? Thank you.

  • Floating images with multiple sizes in CSS

    - by Jamie Chapman
    I'm wanting to be able to create a banner of floating images based on what are uploaded via users. The tool needs to have images of 50x50 and 100x100. At the moment, I just want to randomly display the images and tried to apply float:left. However, as you can see below - it leaves gaps. Is there an easy way to do this without programatically positioning the images? If you want the code so far, it's here: .wall { width: 300px; background-color: red; display: table; } .wall img { float: left; } and <div class="wall"> <img src="man1.png" alt=""/> <!-- ETC... !--> </div>

  • Strategy for Storing Multiple Nullable Booleans in SQL

    - by Eric J.
    I have an object (happens to be C#) with about 20 properties that are nullable booleans. There will be perhaps a few million such objects persisted to a SQL database (currently SQL Server 2008 R2, but MySQL may need to be supported in the future). The instances themselves are relatively large because they contain about a paragraph of text as well as some other unrelated properties. For a given object instance, most of the properties will be null most of the time. When users search for instances of such objects, they will select perhaps 1-3 of the nullable boolean properties and search for instances where at least one of those 1-3 properties is non-null (OR search). My first thought is to persist the object to a single table with nullable BIT columns representing the nullable boolean properties. However, this strategy will require one index per BIT column to avoid performing a table scan when searching. Further, each index would not be particularly selective since there are only three possible values per index. Is there a better way to approach this problem?

  • MySQL, join one item to multiple items in a single query

    - by bschaeffer
    Say I've got two tables. One contains a list of items, and one contains pictures of the items. Something like this: Items +----+---------+ | id | name | +----+---------+ | 1 | oranges | | 2 | apples | +----+---------+ Pictures +----+---------+ | id | item_id | +----+---------+ | 1 | 1 | | 2 | 2 | | 3 | 2 | +----+---------+ My question is this: is it possible in a single query to select item 2 from Items and join all the rows in the Pictures table whose item_id references that same id? I am sure I've tried almost everything I can think of, but nothing is coming to mind. I apologize if the answer to this is simple, but It's just escaping me right now.

  • Consuming WCF REST service in multiple ways (.Net, plain XML)

    - by Jan Jongboom
    I have become quite frustrated of WCF as I just want to use this simple scenario: Provide a webservice using REST, with a UriTemplate like /method/{param1}/{param2}/ and a 3th parameter that is sent to the service as XML as POST data. Use just plain XML, no SOAP overhead. Be able to generate a proxy in Visual Studio so a .Net using client can easily use the service (don't care about SOAP overhead here). I can create 1. and 2. but no way I can use 3. I tried adding both webHttpBinding and basicHttpBinding endpoints in my services config; I fooled around with the <services/> tag, but I just can't get this working. What am I missing here?! N.B. I checked out this article: http://stackoverflow.com/questions/186631/rest-soap-endpoints-for-a-wcf-service but nothing what is described there seems to work here?!

  • Multiple asserts in single test?

    - by Gern Blandston
    Let's say I want to write a function that validates an email address with a regex. I write a little test to check my function and write the actual function. Make it pass. However, I can come up with a bunch of different ways to test the same function ([email protected]; [email protected]; test.test.com, etc). Do I put all the incantations that I need to check in the same, single test with several ASSERTS or do I write a new test for every single thing I can think of? Thanks!

  • Scala : cleanest way to recursively parse files checking for multiple strings

    - by fred basset
    Hi All, I want to write a Scala script to recursively process all files in a directory. For each file I'd like to see if there are any cases where a string occurs at line X and line X - 2. If a case like that occurs I'd like to stop processing that file, and add that filename to a map of filenames to occurrence counts. I just started learning Scala today, I've got the file recurse code working, and need some help with the string searching, here's what I have so far: import java.io.File import scala.io.Source val s1= "CmdNum = 506" val s2 = "Data = [0000,]" def processFile(f: File) { val lines = scala.io.Source.fromFile(f).getLines.toArray for (i = 0 to lines.length - 1) { // want to do string searches here, see if line contains s1 and line two lines above also contains s1 //println(lines(i)) } } def recursiveListFiles(f: File): Array[File] = { val these = f.listFiles if (these != null) { for (i = 0 to these.length - 1) { if (these(i).isFile) { processFile(these(i)) } } these ++ these.filter(_.isDirectory).flatMap(recursiveListFiles) } else { Array[File]() } } println(recursiveListFiles(new File(args(0))))

  • Java Web App: Passing form parameters across multiple pages

    - by digiarnie
    Hi, what is the best practice or best way of passing form parameters from page to page in a flow? If I have a flow where a user enters data in a form and hits next and repeats this process until they get to an approval page, what ways could I approach this problem to make the retention of data as simple as possible over the flow? I guess you could put all the information as you go in the session but could you get into memory issues if a lot of people are using your app and going through the flow at the same time?

  • What is faster: multiple `send`s or using buffering?

    - by dauerbaustelle
    I'm playing around with sockets in C/Python and I wonder what is the most efficient way to send headers from a Python dictionary to the client socket. My ideas: use a send call for every header. Pros: No memory allocation needed. Cons: many send calls -- probably error prone; error management should be rather complicated use a buffer. Pros: one send call, error checking a lot easier. Cons: Need a buffer :-) malloc/realloc should be rather slow and using a (too) big buffer to avoid realloc calls wastes memory. Any tips for me? Thanks :-)
