• Load XML file into object. Best method?

  - by Cypher

  Hello, We are receiving an XML file from our client. I want to load the data from this file into a class, but am unsure about which way to go about it. I have an XSD to defining what is expected in the XML file, so therefore i can easily validate the XML file. Can i use the XSD file to load the data into a POCO, using some sort of serialization? The other way i was thinking was to load the xml into a XMLDocument and use XPath to populate each property in my class. Cheers for any advice

• Pass Alot of Parameters on a Form to Action Struts2

  - by Neeraj

  I have been working on migrating a web application from Struts1 to Struts2. I have a simple Form with around 45 Fields (basically a grid with data). I have to capture all those in Struts2 Action.I noticed that in struts2 we have OGNL through which we just write getters setters in action itself by declaring fields locally to get those variables flowing in the request. I cannot write 45 getters/setters in my action, there must be a way to pass whole object(a POJO) from jsp to Action layer. In Struts 1, we normally get a ActionForm Object and/or get request parameters in a map and then populate. Any help or suggestions will be appreciated.

• Dashcode Web App: How to programmatically manipulate bound array in dataSource?

  - by Kross

  Hi Everyone, I've started using Dashcode to write an interface for presenting the report data for some of our Cocoa tools. I am using a Dashcode data source and bindings to populate the elements in the WebView, and it all seems to be working well so far. One of the objects in my dataSource is an array of objects that I would like to manipulate programmatically. I can change the object values in the array just fine but if I want to replace the array, or any objects in the array, my bound table isn't able to observe the added objects. Here is the code that I thought would let me easily replace the bound array with new content: var dataSource = dashcode.getDataSource("reportData"); var newDetailArray = testArray(); dataSource.setValueForKeyPath(newDetailArray, "content.detailArray"); But this throws the exception: Exception while binding "content" to keypath "arrangedObjects " TypeError: Result of expression 'this.object.valueForKeyPath' [undefined] is not a function. Is there something I'm missing that will let me easily manipulate the array's contents programmatically?

• Temporary intermediate table

  - by user289429

  In our project to generate massive reports in oracle we use some permanent table to hold intermediate results. For example to generate one report we run few queries and populate the table, at the final step we join the intermediate table with huge application tables. These intermediate tables are cleared for next report run. We have few concerns in performance areas. These intermediate tables are transactional and don't have statistics. Is it good idea to join these with application tables which are partitioned and have up to date statistics. We need these results stored in the intermediate tables to be available across requests from UI hence we are not in a position to use oracle provided temporary tables. Any thoughts on what could be done would be appreciated.

• How to enable/create elements on the fly

  - by Simon S

  Hi all I am using a combination of PHP, jQuery and Spry to serve a series of listboxes in which a user will select first the type of vehicle, then the make, then the model and finally the specific model. All my listboxes (SELECT) are working fine, and they update properly using the Spry elements. Each listbox is populated from a different Spry XML Dataset, and this is my problem. If I present all four listboxes to the user, the script has to go and fetch all four lots of XML to populate all four listboxes, taking several seconds. What I want to do is to create/enable the listboxes in order, so at the user selects from the first listbox, the second is created/enabled, when they select from the second, the third is created/enabled... and so on. Setting the disabled attribute is no good because the script has already fetched the XML before this is processed. Any ideas?? Si

• Filter rows from Cursor so they don't show up in ListView

  - by Richard

  I have a Cursor that returns rows I use with a SimpleCursorAdapter to populate a ListView. I would like to filter some of the rows so they don't get displayed in my ListView. I use the data from the rows elsewhere in my Activity so I don't want to change my SQL to filter them with a WHERE clause. What is the best way to keep a row from being displaying in my ListView? Ideally I would check a column in my row and then only add rows to the ListView that satisfy a condition.

• C# How to create objects without class definitions?

  - by JL

  Is it possible to create objects at designtime without having to have hard coded class definitions, then populate properties with primitives or even strongly typed data types? This might sound confusing, so I will attempt to give you a use case scenario. Use case: You have an XML config file that could hold configuration values for connecting to various systems in an SOA application. In C# the XML file is read, but for each system the configuration properties are different (e.g: SQL might have a connection string, while SharePoint might need a username + password + domain + url, while yet an smtp server would need username + password + port + url) So instead of creating static classes as follows public class SharePointConfiguration or public class SQLConfiguration, then have each class with custom properties (this is cumbersome) or using a 1990's method, an arrayList or some named collection Is there not a more preferred way to achieve this? Taking advantage of new language features, that can still offer design time intellisense, which would make the code easier to maintain and less prone to error. Thanks

• DB2 Child Table - Auto Delete With Parent

  - by gamerzfuse

  I have a bit of a task before me. (DB2 Database) I need to create a table that will be a child table (is that what it is called in SQL?) I need it so that it has a foreign key constraint with my other table, so when the parent table is modified (record deleted) the child table also loses that record. Once I have the table, I also need to populate it with the data from the other table (if there is an easy way to UPDATE this). If you could point me in the right direction, this would help alot, as I do not even know what syntax to look for. Thanks in advance

• Is it safe to display user input as input values without sanitation?

  - by Svish

  Say we have a form where the user types in various info. We validate the info, and find that something is wrong. A field is missing, invalid email, et cetera. When displaying the form to the user again I of course don't want him to have to type in everything again so I want to populate the input fields. Is it safe to do this without sanitation? If not, what is the minimum sanitation that should be done first? And to clearify: It would of course be sanitized before being for example added to a database or displayed elsewhere on the site.

• Differentiate VMware network adapter from physical network adapters

  - by Venkat

  I have to differentiate between the real addresses and the VM addresses using any Windows API. I'm using Getadaptersaddresses API to populate a list of ipaddresses for the local machine. I need to extract only the "real" addresses apart from the addresses associated with the VMware network adapter and other addresses(auto-configuration and tunnel adapter addresses) I've not been able to find any API or any flag to differentiate this. Is there any way this can be done? PS:The IfType flag in the IP_ADAPTER_ADDRESSES structure returned by Getadaptersaddresses doesn't help me differentiate between VMware addresses and the real addresses

• press button to open web page from app

  - by Lee

  I have an app that I want to interact with a web page. Basically I want to press a button and the web page will open in a new view... Sorry I wasn't clear, I am developing on a Mac for an iPhone. Currently I have a "locate me" app that displays your Latitude and Longitude. I want to use those variables to populate 2 of the blanks on a PHP web page/form I have developed. I have added a label and button to my current app, when the button is pressed the URL with the Lat and Long (as passed vars) are displayed in the label. I want those vars to appear on my web page. Hope this is clearer... Solved: I just added these lines of code I found here: NSURL *url = [ [ NSURL alloc ] initWithString: @"http://www.cnn.com" ]; [[UIApplication sharedApplication] openURL:url];

• Java application failing on special characters.

  - by Scottm

  An application I am working on reads information from files to populate a database. Some of the characters in the files are non-English, for example accented French characters. The application is working fine in Windows but on our Solaris machine it is failing to recognise the special characters and is throwing an exception. For example when it encounters the accented e in "Gérer" it says :- Encountered: "\u0161" (353), after : "\'G\u00c3\u00a9rer les mod\u00c3" (an exception which is thrown from our application) I suspect that in order to stop this from happening I need to change the file.encoding property of the JVM. I tried to do this via System.setProperty() but it has not stopped the error from occurring. Are there any suggestions for what I could do? I was thinking about setting the basic locale of the solaris platform in /etc/default/init to be UTF-8. Does anyone think this might help? Any thoughts are much appreciated.

• Seam log4j credential logs

  - by Marc

  In Seam, using log4, I would like to have my info, warn and error always logging the logged in user (if so) name to be logged with whatever the log message is. Being a consistant thing I do not want to have to grab the logged-in user name, and prefix the message. so I attempted to populate the log4j NDC to have it as a field of the log message. Pushing the user name on successful login: NDC.push(credentials.getUsername()); Which works, but the NDC is managed per thread, so once another thread processes a request from the same logged in user, the trace of this user name is lost. I was thinking that there should be a common pattern to accomplish this simple task which is attaching each log message to the logged user, using the NDC or not, to know exactly what user triggered what action. Anyone knows the appropriate way to accomplish this?

• triggering an onchange event of a select box

  - by swathi

  Hi all, I have a select box, which i can populate using two methods. First - Just by selecting any one of the option in the select box. Second - I have a link just beside the select box.Clicking this link takes me to a page2, which has the same options but as links in page2.When i click one of them , it populates the select box. Selecting the option directly from the "select" triggers an onchange event in it. But when i click the link, select my required option from that page, it does not trigger the onchange event in the select box. I am not sure where i am doing a mistake. Thanks in advance.

• Identifying all types with some attribute

  - by Tom W

  Hello SO; I have an issue with .Net reflection. The concept is fairly new to me and I'm exploring it with some test cases to see what works and what doesn't. I'm constructing an example wherein I populate a set of menus dynamically by scanning through my Types' attributes. Basically, I want to find every type in my main namespace that declares 'SomeAttribute' (doesn't matter what it is, it doesn't have any members at present). What I've done is: For Each itemtype As Type In Reflection.Assembly.GetExecutingAssembly().GetTypes If itemtype.IsDefined(Type.GetType("SomeAttribute"), False) Then 'do something with the type End If Next This crashes the application on startup - the first type it identifies is MyApplication which is fairly obviously not what I want. Is there a right and proper way to look for all the 'real' 'sensible' types - i.e. classes that I've defined - within the current assembly?

• Seeking tutorial: introduction to ODBC with Delphi

  - by mawg

  I have a lot of embedded C/C++/Ada experience and an outdated smattering of Delphi plus some database stuff. Now I have to implement an app in Delphi which can manipulate MySql, Oracle, maybe MS Access. In short, I need ODBC. I need to programmatically created a database, define its structure and populate its contents, then later query its existence and programmatically search. I would prefer not to use 3rd party components, unless there is a compelling reason to do so (performance ought not to be an issue for the app, it won't have much data or be run often, at least not in v1.0) . Can anyone point me at a tutorial which can get me up to speed? Thanks

• java detect clicked buttons

  - by user253530

  I have multiple panels on a JFrame window. I am going to populate each panel differently every time. For example: i start the GUI: (image center panel, right panel, bottom panel). Center panel is populated with 20 buttons, right panel with 10 buttons and bottom panel with 3. second start of the GUI (same gui). Center panel has 50 buttons, right panel has 12 buttons, bottom has 3. So everytime there is a random number of buttons, impossible to be all uniquely named. Given the fact that I don't have a unique name for each button (just a list) I would like to know which buttons were clicked according to the panel they belong to. is that possible?

• How can I copy an XmlNode from one XmlDocument to another?

  - by Chris Wenham

  I'm building a tool that authors/edits XML files, and I want to be able to populate it with template fragments defined in another XML file. For example, the tool has an "Add FooBarBaz Element" button that adds a element to the new document being created, and I want to add FooBarBaz by copying it from a template. Or let's say this is my template file: <Templates> <FooBarBaz Attribute="Value"> <ChildElement/> </FooBarBaz> </Templates> I can then grab a template fragment with .GetElementsByTagName("FooBarBaz"), and I'd like to be able to inject it into the new document with something like .AppendChild(templateNode). But the problem is that an XmlNode cannot be copied from one XmlDocument to another, even if you use .Clone() or .CloneNode(), because AppendChild() throws an exception saying that the template element belongs to another context. Is there an easy way to copy a System.Xml.XmlNode between System.Xml.XmlDocuments?

• MVC binding form data problem.

  - by John

  I am using an object that matches all the fields in my form. I then use the default binding to populate the object in my action, like this; public ActionResult GetDivisionData(DivisionObj FormData) My DivisionObj initializes all it's values to string.empty in the constructor. The problem is that when the binder populates the model from the posted form data, any data that is not posted is set to null in the object, eventhough I initialized the object to contain empty strings. Is there a way to change this so that unposted data will be an empty string.

• Asp.Net MVC Handle Drop Down Boxes that are not part of the Model

  - by Pino

  I have a small form which the user must fill in and consists of the following fields. Name (Text) Value (Text) Group (Group - Is a list of option pulled from a database table) Now the Model for this View looks like so, public string Name { get; set; } public string Value { get; set; } public int GroupID { get; set; } Now the view is Strongly Typed to the above model. What method would one use to populate the drop down list? Since the data is not contained within the Model (It could be contained in the Model) should we be using Temp/View data? A HTML Helper? What would be the ideal way to achieve this.
