• Java NIO (Netty): How does Encryption or GZIPping work in theory (with filters)

  - by Tom

  Hello Experts, i would be very thankfull if you can explain to me, how in theory the "Interceptor/Filter" Pattern in ByteStreams (over Sockets/Channels) work (in Asynchronous IO with netty) in regard to encryption or compression of data. Given I have a Filter that does GZIPPING. How is this internally implemented? Does the Filter "collect" so many bytes form the channel, that this is a usefull number of bytes that can then be en/decoded? What is in general the minimal "blocksize(data to encode/decode in a chunk)" of socket based gzipping? Does this "blocksize" have to be negotiated in advance between server and client? What happens if the client does not send enough data to "fill" the blocksize (due to a network conquestion) but does not close the connection. Does this mean the other side will simply wait until it gets enough bytes to decode or until a timeout occoures...How is the Filter pattern the applied? The compression filter will de/compress the blocksize of bytes and then store them again in the same buffer would (in the case of netty) i normally be using the ChannelHanlderContext to pass the de/encoded data to the next filter?... Any explanations/links/tutorials (for beginners;-) will be very much appreciated to help me understand how for example encryption/compressing are implemented in socket based communication with filters/interceptor pattern. thank you very much tom

• xsd.exe - schema to class - for use with WCF

  - by NealWalters

  I have created a schema as an agreed upon interface between our company and an external company. I am now creating a WCF C# web service to handle the interface. I ran the XSD utility and it created a C# class. The schema was built in BizTalk, and references other schemas, so all-in-all there are over 15 classes being generated. I put [DataContract} attribute in front of each of the classes. Do I have to put the [DataMember] attribute on every single property? When I generate a test client program, the proxy does not have any code for any of these 15 classes. We used to use this technique when using .asmx services, but not sure if it will work the same with WCF. If we change the schema, we would want to regenerate the WCF class, and then we would haev to each time redecorate it with all the [DataMember] attributes? Is there an newer tool similar to XSD.exe that will work better with WCF? Thanks, Neal Walters SOLUTION (buried in one of Saunders answer/comments): Add the XmlSerializerFormat to the Interface definition: [OperationContract] [XmlSerializerFormat] // ADD THIS LINE Transaction SubmitTransaction(Transaction transactionIn); Two notes: 1) After I did this, I saw a lot more .xsds in the my proxy (Service Reference) test client program, but I didn't see the new classes in my intellisense. 2) For some reason, until I did a build on the project, I didn't get all the classes in the intellisense (not sure why).

• How to parse kanji numeric characters using ICU?

  - by Aki

  I'm writing a function using ICU to parse an Unicode string which consists of kanji numeric character(s) and want to return the integer value of the string. "?" = 5 "???" = 31 "???????" = 5972 I'm setting the locale to Locale::getJapan() and using the NumberFormat::parse() to parse the character string. However, whenever I pass it any Kanji characters, the parse() method is returning U_INVALID_FORMAT_ERROR. Does anyone know if ICU supports Kanji character strings in the NumberFormat::parse() method? I was hoping that since I'm setting the Locale to Japanese that it would be able to parse Kanji numeric values. Thanks! #include <iostream> #include <unicode/numfmt.h> using namespace std; int main(int argc, char **argv) { const Locale &jaLocale = Locale::getJapan(); UErrorCode status = U_ZERO_ERROR; NumberFormat *nf = NumberFormat::createInstance(jaLocale, status); UChar number[] = {0x4E94}; // Character for '5' in Japanese '?' UnicodeString numStr(number); Formattable formattable; nf->parse(numStr, formattable, status); if (U_FAILURE(status)) { cout << "error parsing as number: " << u_errorName(status) << endl; return(1); } cout << "long value: " << formattable.getLong() << endl; }

• How to correctly set the ORACLE_HOME variable on Ubuntu 9.x?

  - by nowarninglabel

  I have the same problem as listed here: http://stackoverflow.com/questions/52239/oracle-lost-sysdba-password although I did not lose the password, I entered it twice in the configure script originally, and then when I went to login (localhost:8080/apex, password not accepted. I don't have anything in the database, I just want to install and use Oracle-XE. I have tried apt-get removing it twice and reinstalling, but if I try to run /etc/init.d/oracle-xe configure again and I get "Oracle Database 10g Express Edition is already configured" despite the second time removing any folders I could find for Oracle XE. I tried running sqlplus "/ as sysdba" but all I get is: "Error 6 initializing SQL*Plus Message file sp1.msb not found SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory" I tried setting the variable via export. (also tried set). Tried: "export ORACLE_HOME=/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin/sqlplus" and all the subdirectories of that. Same error every time. What is the ORACLE_HOME supposed to be set to? The only reference I have seen either just say general or say the above up to the version number then "/db_1". I do no thave a db_1. Let me know if need any clarification. Don't understand what I did wrong in this process.

• Casting generics and the generic type

  - by Kragen

  Consider, I have the following 3 classes / interfaces: class MyClass<T> { } interface IMyInterface { } class Derived : IMyInterface { } And I want to be able to cast a MyClass<Derived> into a MyClass<IMyInterface> or visa-versa: MyClass<Derived> a = new MyClass<Derived>(); MyClass<IMyInterface> b = (MyClass<IMyInterface>)a; But I get compiler errors if I try: Cannot convert type 'MyClass<Derived>' to 'MyClass<IMyInterface>' I'm sure there is a very good reason why I cant do this, but I can't think of one. As for why I want to do this - The scenario I'm imagining is one whereby you ideally want to work with an instance of MyClass<Derived> in order to avoid lots of nasty casts, however you need to pass your instance to an interface that accepts MyClass<IMyInterface>. So my question is twofold: Why can I not cast between these two types? Is there any way of keeping the niceness of working with an instance of MyClass<Derived> while still being able to cast this into a MyClass<IMyInterface>?

• Spinner in Android crashing when visibilty changes while handling OnClick in a button

  - by Dave George

  I have a spinner in UI, which I want to hide when I handle onClick method for a button. But the application is crashing all the time. Is it that I can't use the setVisibility(View.Gone) on spinners (it is not written anywhere). If I comment it out, then application run fine. I am getting NullPointerException and I am using RelativeLayout. Also, can I do this: public void onItemSelected(AdapterView<?> arg0, View view, int pos, long arg3) { // TODO Auto-generated method stub Toast.makeText(SpinnerActivity.this,selected , Toast.LENGTH_SHORT).show(); spinner.setVisibility(View.GONE); } } Spinner code fore reference: itemsCity=getResources().getStringArray(R.array.cities_array); ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource( this, R.array.cities_array, android.R.layout.simple_spinner_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinnerCity.setAdapter(adapter); And here is Button code: private class BtClickListner implements View.OnClickListener{ @Override public void onClick(View v) { essEditText.setVisibility(View.GONE); spinnerCity.setEnabled(false);// Getting exception here // Also tried spinnerCity.setVisibility(View.GONE);// Exception SameBt.setVisibility(View.GONE);// This is same button for which I am handliing event, but it allows me to change tis property at run time. }

• LogonUser -> CreateProcessAsUser from a system service

  - by Josh K

  I've read all the posts on Stack Overflow about CreateProcessAsUser and there are very few resolved questions, so I'm not holding my breath on this one. But it seems like I'm definitely missing something, so it might be easy. The target OS is Windows XP. I have a service running as "Local System" from which I want to create a process running as a different user. For that user, I have the username and password, so LogonUser goes fine and I get a token for the user (in this case, an Administrator account.) I then try to use that token to call CreateProcessAsUser, but it fails because that token does not come with SeAssignPrimaryTokenPrivilege - however, it does have SeIncreaseQuotaPrivilege. (I used GetTokenInformation to dump all the privileges associated with that token.) According to the MSDN page for CreateProcessAsUser, you need both privileges in order to call CreateProcessAsUser successfully. It also says you don't need the SeAssignPrimaryTokenPrivilege if the token you pass in to CreateProcessAsUser() is a "restricted version of the calling process' primary token", which I can create with CreateRestrictedToken(), but then it will be associated with the Local System user and not the target user I'm trying to run the process as. So how would I create a logon token that is both a restricted version of the calling process' primary token, AND is associated with a different user? Thanks! Note that there is no need for user interaction in here - it's all unattended - so there's no need to do stuff like grabbing WINSTA0, etc.

• Cannot connect Linux XAMPP PHP to SQL Server database.

  - by Jim

  I've searched many sites without success. I'm using XAMPP 1.7.3a on Ubuntu 9.1. I have used the methods found at http://www.webcheatsheet.com/PHP/connect_mssql_database.php, they all fail. I am able to "connect" with a linked database through MS Access, however, that is not an acceptable solution as not all users will have Access. The first method (at webcheatsheet) uses mssql_connect, et.al. but I get this error from the mssql_connect() call: Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server: [my server] in [my code] [my server] is the server address, I have used both the host name and the IP address. [my code] is a reference to the file and line number in my .php file. Is there a log file somewhere that would have more information about the failure, both on my machine and SQL Server? We do not have a bona-fide DBA, so I will need specific information to pass on if the issue seems to be on the server side. All assistance is appreciated, including RTFM when the location of the M is provided! Thanks

• Routing an ActiveMq topic to an external broker.

  - by chillitom

  Hi All, I have an ActiveMq topic which I wish to transform and share with an external broker. At present I have the following which performs the transformation: <camelContext id="camel" xmlns="http://activemq.apache.org/camel/schema/spring"> <route> <from uri="activemq:topic:OriginalTopic"/> <to uri="xslt:file:///xslt/transformation.xsl"/> <to uri="activemq:topic:NewTopic"/> </route> </camelContext> However this just sends the message to the current broker network. I'd like to pass the NewTopic messages to an external broker only. I don't want to join the external broker using a <networkConnector .. > as only this topic should be send to the external broker and no others. Is there a simple way to route messages to an external broker? Many thanks.

• How do I repopulate the view model in ASP.NET MVC 2 after a validation error?

  - by Keltex

  I'm using ASP.NET MVC 2 and here's the issue. My View Model looks something like this. It includes some fields which are edited by the user and others which are used for display purposes. Here's a simple version public class MyModel { public decimal Price { get; set; } // for view purpose only [Required(ErrorMessage="Name Required")] public string Name { get; set; } } The controller looks something like this: public ActionResult Start(MyModel rec) { if (ModelState.IsValid) { Repository.SaveModel(rec); return RedirectToAction("NextPage"); } else { // validation error return View(rec); } } The issue is when there's a validation error and I call View(rec), I'm not sure the best way to populate my view model with the values that are displayed only. The old way of doing it, where I pass in a form collection, I would do something like this: public ActionResult Start(FormCollection collection) { var rec = Repository.LoadModel(); UpdateModel(rec); if (ModelState.IsValid) { Repository.SaveModel(rec); return RedirectToAction("NextPage"); } else { // validation error return View(rec); } } But doing this, I get an error on UpdateModel(rec): The model of type 'MyModel' could not be updated. Any ideas?

• JSF Render response programmatically

  - by Shamik

  I have one parent page with a parentManagedBean (attached to Session Scope). On click of a button on this parent page, one popup comes which has a childManagedBean (attached to Request scope). Now ChildManagedBean holds a reference to parentManaged bean through JSF's managed property facility. On this popup window, user selects some option which populates a large value object. I use the managed property of childManagedBean to set the values from this large object to that of parentManagedBean. Problem is - The parent page shows a link, on click of which a popup comes, on selection of the popup, the popup disappears and set the values to the parentManaged bean. So far so good, but the newly set values need to appear on the parent page. This is where I am stuck. How to programmatically render the master page/render page when I am at the child managed bean? Is there a way I can get handle of the parent page and refresh it? Note: I'm using JSF 1.1 EDIT- After following the solution of "resubmit-ing the form" from javascript, I am seeing that the old form is getting resubmitting which overwrites all of my changed values.

• Validation in n-tier asp.net mvc applications

  - by sTodorov

  Dear Stack Overflow gurus, I am looking for some practical/theoretical information regarding best practices for validation in asp.net mvc n-tier applications. I am working on a .Net application divided into the following layers: UI - Mvc3 BLL layer - all business rules. Decoupled from data access and UI layers through interfaces DAL layer - Data access with the repository pattern, EF4 and pocos Now, I am looking for a nice, clean and transparent way to specify my validation rules. Here are some thoughts on the matter so far: UI validation should only be responsible for user input and its validity. BLL validation should be handling the validity of the data regarding the application business rules. My main concern is how to bind the BLL and UI validation in the most efficient way. One think I am would like to avoid is having the UI check in a collection of validation and adding manually errors to the ModelState. Furthermore, I do not want to pass the ModelState to the BLL to be populated in there. I will appreciate any thoughts on the matter. P.S. Should this question be marked as a discussion ?

• Call long running operation in WSS feature OnActivated Event

  - by dirq

  More specifically - How do I reference SPContext in Web Service with [SoapDocumentMethod(OneWay=true)]? We are creating a feature that needs to run a job when a site is created. The job takes about 4 minutes to complete. So, we made a web service that we can call when the feature is activated. This works but we want it to run asynchronously now. We've found the SoapDocumentMethod's OneWay property and that would work awesomely but the SPContext is now NULL. We have our web services in the _vti_bin virtual directory so it's available in each Windows Sharepoint Services site. I was using the SPContext.Current.Web to get the site and perform the long running operation. I wanted to just fire and forget about it by returning a soap response right away and letting the process run. How can I get the current SPContext? I used to be able to do this in my web service: SPWeb mySite = SPContext.Current.Web; Can I get the same context when I have the [SoapDocumentMethod(OneWay=true)] attribute applied to my web service? Or must I recreate the SPWeb from the url? This is similar to this thread: http://stackoverflow.com/questions/340192/webservice-oneway-and-new-spsitemyurl Update: I've tried these two ways but they didn't work: SPWeb targetSite = SPControl.GetContextWeb(this.Context); SPWeb targetSite2 = SPContext.GetContext(this.Context).Web;

• Shell script to emulate warnings-as-errors?

  - by talkaboutquality

  Some compilers let you set warnings as errors, so that you'll never leave any compiler warnings behind, because if you do, the code won't build. This is a Good Thing. Unfortunately, some compilers don't have a flag for warnings-as-errors. I need to write a shell script or wrapper that provides the feature. Presumably it parses the compilation console output and returns failure if there were any compiler warnings (or errors), and success otherwise. "Failure" also means (I think) that object code should not be produced. What's the shortest, simplest UNIX/Linux shell script you can write that meets the explicit requirements above, as well as the following implicit requirements of otherwise behaving just like the compiler: - accepts all flags, options, arguments - supports redirection of stdout and stderr - produces object code and links as directed Key words: elegant, meets all requirements. Extra credit: easy to incorporate into a GNU make file. Thanks for your help. === Clues === This solution to a different problem, using shell functions (?), Append text to stderr redirects in bash, might figure in. Wonder how to invite litb's friend "who knows bash quite well" to address my question? === Answer status === Thanks to Charlie Martin for the short answer, but that, unfortunately, is what I started out with. A while back I used that, released it for office use, and, within a few hours, had its most severe drawback pointed out to me: it will PASS a compilation with no warnings, but only errors. That's really bad because then we're delivering object code that the compiler is sure won't work. The simple solution also doesn't meet the other requirements listed. Thanks to Adam Rosenfield for the shorthand, and Chris Dodd for introducing pipefail to the solution. Chris' answer looks closest, because I think the pipefail should ensure that if compilation actually fails on error, that we'll get failure as we should. Chris, does pipefail work in all shells? And have any ideas on the rest of the implicit requirements listed above?

• Problem with XStream Marshalling to return xml and json

  - by MiKu

  When i use new XStream().toXml(someObject); it returns following xml... <response> <status>SUCCESS</status> <isOwnershipVerified class="boolean">false</isOwnershipVerified> </response> and, when i use new XStream(new JsonHierarchicalStreamDriver()).toXml(someObject); it returns following json... {"response": { "status": "SUCCESS", "isOwnershipVerified": { "@class": "boolean""false"} }} Now, since i want to get rid of class attribute altogether (read it not to alias it with anything else, but to remove it) i use following code. XStream xStream = new XStream(); StringWriter writer = new StringWriter(); xStream.marshal(this, new PrettyPrintWriter(writer) { @Override public void addAttribute(final String key, final String value) { if (!key.equals("class")) { super.addAttribute(key, value); } } }); return writer.toString(); which gives follwing xml... <response> <status>SUCCESS</status> <isOwnershipVerified>false</isOwnershipVerified> </response> but, when i pass new JsonHierarchicalStreamDriver() while xStream object creation above, it does NOT return json. it returns the same xml shown above. What is wrong going on here? Thanks in advance...

• Call dll - pcshll32.dll using delphi

  - by Davis

  Hi, I need to call hllapi function of pcshll32.dll using delphi. It's works with personal communications of ibm. How can i change the code bellow to delphi ? Thanks !!! The EHLLAPI entry point (hllapi) is always called with the following four parameters: EHLLAPI Function Number (input) Data Buffer (input/output) Buffer Length (input/output) Presentation Space Position (input); Return Code (output) The prototype for IBM Standard EHLLAPI is: [long hllapi (LPWORD, LPSTR, LPWORD, LPWORD); The prototype for IBM Enhanced EHLLAPI is: [long hllapi (LPINT, LPSTR, LPINT, LPINT); Each parameter is passed by reference not by value. Thus each parameter to the function call must be a pointer to the value, not the value itself. For example, the following is a correct example of calling the EHLLAPI Query Session Status function: #include "hapi_c.h" struct HLDQuerySessionStatus QueryData; int Func, Len, Rc; long Rc; memset(QueryData, 0, sizeof(QueryData)); // Init buffer QueryData.qsst_shortname = ©A©; // Session to query Func = HA_QUERY_SESSION_STATUS; // Function number Len = sizeof(QueryData); // Len of buffer Rc = 0; // Unused on input hllapi(&Func, (char *)&QueryData, &Len, &Rc); // Call EHLLAPI if (Rc != 0) { // Check return code // ...Error handling } All the parameters in the hllapi call are pointers and the return code of the EHLLAPI function is returned in the value of the 4th parameter, not as the value of the function.

• Rails, RSpec and Webrat: Expected output matches rendered output but still getting error in view spe

  - by Anthony Burns

  Hello all, I've just gotten started using BDD with RSpec/Cucumber/Webrat and Rails and I've run into some frustration trying to get my view spec to pass. First of all, I am running Ruby 1.9.1p129 with Rails 2.3.2, RSpec and RSpec-Rails 1.2.6, Cucumber 0.3.11, and Webrat 0.4.4.

• Automatic Adjusting Range Table

  - by Bradford

  I have a table with a start date range, an end date range, and a few other additional columns. On input of a new record, I want to automatically adjust any overlapping date ranges (shrinking them to allow for the new input). I also want to ensure that no overlapping records can accidentally be inserted into this table. I'm using Oracle and Java for my application code. How should I enforce the prevention of overlapping date ranges and also allow for automatically adjusting overlapping ranges? Should I create an AFTER INSERT trigger, with a dbms_lock to serialize access, to prevent the overlapping data. Then in Java, apply the logic to auto adjust everything? Or should that part be in PL/SQL in stored procedure call? This is something that we need for a couple other tables so it'd be nice to abstract. If anyone has something like this already written, please share :) I did find this reference: http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:474221407101 Here's an example of how each of the 4 overlapping cases should be handled for adjustment on insert: = Example 1 = In DB (Start, End, Value): (0, 10, 'X') **(30, 100, 'Z') (200, 500, 'Y') Input (20, 50, 'A') Gives (0, 10, 'X') **(20, 50, 'A') **(51, 100, 'Z') (200, 500, 'Y') = Example 2 = In DB (Start, End, Value): (0, 10, 'X') **(30, 100, 'Z') (200, 500, 'Y') Input (40, 80, 'A') Gives (0, 10, 'X') **(30, 39, 'Z') **(40, 80, 'A') **(81, 100, 'Z') (200, 500, 'Y') = Example 3 = In DB (Start, End, Value): (0, 10, 'X') **(30, 100, 'Z') (200, 500, 'Y') Input (50, 120, 'A') Gives (0, 10, 'X') **(30, 49, 'Z') **(50, 120, 'A') (200, 500, 'Y') = Example 4 = In DB (Start, End, Value): (0, 10, 'X') **(30, 100, 'Z') (200, 500, 'Y') Input (20, 120, 'A') Gives (0, 10, 'X') **(20, 120, 'A') (200, 500, 'Y') The algorithm is as follows: given range = g; input range = i; output range set = o if i.start <= g.start if i.end >= g.end o_1 = i else o_1 = i o_2 = (o.end + 1, g.end) else if i.end >= g.end o_1 = (g.start, i.start - 1) o_2 = i else o_1 = (g.start, i.start - 1) o_2 = i o_3 = (i.end + 1, i.end)

• How to enable and use HTTP PUT and DELETE with Apache2 and PHP?

  - by Andreas Jansson

  Hi, It should be so simple. I've followed every tutorial and forum I could find, yet I can't get it to work. I simply want to build a RESTful API in PHP on Apache2. In my VirtualHost directive I say: <Directory /> AllowOverride All <Limit GET HEAD POST PUT DELETE OPTIONS> Order Allow,Deny Allow from all </Limit> </Directory> Yet every PUT request I make to the server, I get 405 method not supported. Someone advocated using the Script directive, but since I use mod_php, as opposed to CGI, I don't see why that would work. People mention using WebDAV, but to me that seems like overkill. After all, I don't need DAV locking, a DAV filesystem, etc. All I want to do is pass the request on to a PHP script and handle everything myself. I only want to enable PUT and DELETE for the clean semantics. Thanks, Andreas

• Silverlight HttpWebRequest.Create hangs inside async block

  - by jack2010

  I am trying to prototype a Rpc Call to a JBOSS webserver from Silverlight (4). I have written the code and it is working in a console application - so I know that Jboss is responding to the web request. Porting it to silverlight 4, is causing issues: let uri = new Uri(queryUrl) // this is the line that hangs let request : HttpWebRequest = downcast WebRequest.Create(uri) request.Method <- httpMethod; request.ContentType <- contentType It may be a sandbox issue, as my silverlight is being served off of my file system and the Uri is a reference to the localhost - though I am not even getting an exception. Thoughts? Thx UPDATE 1 I created a new project and ported my code over and now it is working; something must be unstable w/ regard to the F# Silverlight integration still. Still would appreciate thoughts on debugging the "hanging" web create in the old model... UPDATE 2 let uri = Uri("http://localhost./portal/main?isSecure=IbongAdarnaNiFranciscoBalagtas") // this WebRequest.Create works fine let req : HttpWebRequest = downcast WebRequest.Create(uri) let Login = async { let uri = new Uri("http://localhost/portal/main?isSecure=IbongAdarnaNiFranciscoBalagtas") // code hangs on this WebRequest.Create let request : HttpWebRequest = downcast WebRequest.Create(uri) return request } Login |> Async.RunSynchronously I must be missing something; the Async block works fine in the console app - is it not allowed in the Silverlight App?

• Simple Select Statement on MySQL Database Hanging

  - by AlishahNovin

  I have a very simple sql select statement on a very large table, that is non-normalized. (Not my design at all, I'm just trying to optimize while simultaneously trying to convince the owners of a redesign) Basically, the statement is like this: SELECT FirstName, LastName, FullName, State FROM Activity Where (FirstName=@name OR LastName=@name OR FullName=@name) AND State=@state; Now, FirstName, LastName, FullName and State are all indexed as BTrees, but without prefix - the whole column is indexed. State column is a 2 letter state code. What I'm finding is this: When @name = 'John Smith', and @state = '%' the search is really fast and yields results immediately. When @name = 'John Smith', and @state = 'FL' the search takes 5 minutes (and usually this means the web service times out...) When I remove the FirstName and LastName comparisons, and only use the FullName and State, both cases above work very quickly. When I replace FirstName, LastName, FullName, and State searches, but use LIKE for each search, it works fast for @name='John Smith%' and @state='%', but slow for @name='John Smith%' and @state='FL' When I search against 'John Sm%' and @state='FL' the search finds results immediately When I search against 'John Smi%' and @state='FL' the search takes 5 minutes. Now, just to reiterate - the table is not normalized. The John Smith appears many many times, as do many other users, because there is no reference to some form of users/people table. I'm not sure how many times a single user may appear, but the table itself has 90 Million records. Again, not my design... What I'm wondering is - though there are many many problems with this design, what is causing this specific problem. My guess is that the index trees are just too large that it just takes a very long time traversing the them. (FirstName, LastName, FullName) Anyway, I appreciate anyone's help with this. Like I said, I'm working on convincing them of a redesign, but in the meantime, if I someone could help me figure out what the exact problem is, that'd be fantastic.

• Lucene complex structure search

  - by archer

  Basically I do have pretty simple database that I'd like to index with Lucene. Domains are: // Person domain class Person { Set<Pair> keys; } // Pair domain class Pair { KeyItem keyItem; String value; } // KeyItem domain, name is unique field within the DB (!!) class KeyItem{ String name; } I've tens of millions of profiles and hundreds of millions of Pairs, however, since most of KeyItem's "name" fields duplicates, there are only few dozens KeyItem instances. Came up to that structure to save on KeyItem instances. Basically any Profile with any fields could be saved into that structure. Lets say we've profile with properties - name: Andrew Morton - eduction: University of New South Wales, - country: Australia, - occupation: Linux programmer. To store it, we'll have single Profile instance, 4 KeyItem instances: name, education,country and occupation, and 4 Pair instances with values: "Andrew Morton", "University of New South Wales", "Australia" and "Linux Programmer". All other profile will reference (all or some) same instances of KeyItem: name, education, country and occupation. My question is, how to index all of that so I can search for Profile for some particular values of KeyItem::name and Pair::value. Ideally I'd like that kind of query to work: name:Andrew* AND occupation:Linux* Should I create custom Indexer and Searcher? Or I could use standard ones and just map KeyItem and Pair as Lucene components somehow?

• Binding Data to a TextBlock using Domain Data Source

  - by TFisher

  I have a map with hotspots for each state (done in Expression Blend). I capture each MouseEnter of the state (1 thru 50). I pass that into my Domain Data Source: Dim activebox As Path = TryCast(sender, Path) activebox.Fill = mouseOverColor Dim StateID As Integer = CInt(Right(activebox.Name, 2)) Dim _StateContext As New StateContext myDataGrid.ItemsSource = _StateContext.States _StateContext.Load(_StateContext.GetStateByStateIDQuery(StateID.Text)) The above works fine for a datagrid, listbox and even a dataform. But I created a popup with a stackpanel that has textblocks. popupStatesBox.DataContext = ?????????????? popupStatesBox.IsOpen = True 'popup does open but has no data -- popupStatesBox.xaml <Popup x:Name="popupStatsBox" Margin="8,35,0,8" DataContext="{Binding}" IsOpen="false" Width="268" HorizontalAlignment="Left"> <StackPanel x:Name="Layout" Background="Black"> <TextBlock x:Name="tbState" Text="{Binding StateName /> <TextBlock x:Name="tbAbbrev" Text="{Binding Abbreviation}" /> </StackPanel> </Popup> How do I get the textblocks to display the values from the _StateContext. StackPanel has DataContext but no ItemsSource. What am I missing?

• Using Windows Integrated Auth & Anonymous during redirect on IIS7

  - by James Black

  I have an application we bought that I need to integrate, and it uses jakarta connection to get to the application from IIS. So, the basic operation is: user goes to the url Gets redirected to the application SSO is enabled, so redirected back to IIS for fetching of domain credentials Back to application If username is blank show login page, else let user in. This is a simplification of all the steps, but the basic idea is here. My difficulty is that I need both Windows Integrated Auth and anonymous on, as some users won't have credentials, and need to be prompted for a username/password. I have looked at: http://stackoverflow.com/questions/2068546/iis-windows-authentication-before-anonymous already, but the user doesn't get to click on a link to decide. The application goes back to IIS looking for login.aspx and from there I want to either get their domain credentials or pass back to the application empty strings to signify that there are no credentials. It seems this isn't going to be possible though as if anonymous is on it doesn't make the 401 request so the credentials aren't passed. If I can't get this to work with just using an ASP page, could it be done using an ISAPI filter, or a module?
