  - by user1073570

  The following code is not working correctly.

My goal is to eventually build a table of status data and output it on the page is this the wrong way to use the property tag? Thank you in advance for your help.

• Android Read contents of a URL (content missing after in result)

  - by josnidhin

  I have the following code that reads the content of a url public static String DownloadText(String url){ StringBuffer result = new StringBuffer(); try{ URL jsonUrl = new URL(url); InputStreamReader isr = new InputStreamReader(jsonUrl.openStream()); BufferedReader in = new BufferedReader(isr); String inputLine; while ((inputLine = in.readLine()) != null){ result.append(inputLine); } }catch(Exception ex){ result = new StringBuffer("TIMEOUT"); Log.e(Util.AppName, ex.toString()); } in.close(); isr.close(); return result.toString(); } The problem is I am missing content after 4065 characters in the result returned. Can someone help me solve this problem. Note: The url I am trying to read contains a json response so everything is in one line I think thats why I am having some content missing.

• How can I pass a type as a parameter in scala?

  - by rsan

  I'm having a really hard time trying to figure out how can I store or pass a type in scala. What I want to achive is something like this: abstract class Foo( val theType : type ) object Foo{ case object Foo1 extends Foo(String) case object Foo2 extends Foo(Long) } So at some point I can do this: theFoo match{ case String => "Is a string" case Long => "Is a long" } and when obtaining the object being able to cast it: theFoo.asInstanceOf[Foo1.theType] Is this possible? If is possible, is a good aproach? What I'm trying to achieve ultimately is writing a pseudo schema for byte stream treatment. E.g if I have an schema Array(Foo1,Foo1,Foo2,Foo3,Foo1) I could parse Arrays of bytes that complain with that schema, if at some point I have a different stream of bytes I could just write a new schema Array(Foo3, Foo4, Foo5) without having to reimplement parsing logic. Regards,

• Passing object through WCF so that server receives client changes

  - by cvig

  I would like to set up a WCF service so that any changes a client makes to an object I send them are also reflected on the server side. For example, if Assembly A has the following... namespace AssemblyA { public class Person { public string FirstName { get; set; } public string LastName { get; set; } } [ServiceContract] public interface IServer { [OperationContract] Person GetPerson(); } } And Assembly B references Assembly A... using AssemblyA; namespace AssemblyB { class Program { static void Main(string[] args) { <snip> IServer server = factory.CreateChannel(); Person person = server.GetPerson(); person.FirstName = "Kilroy"; person.LastName = "WuzHere"; } } } What is the easiest/best way to make it so that the service's copy of the Person object also reflects the changes that the client makes? Is this even possible?

• how to represent negative number to array of integers ?

  - by stdnoit

  I must convert string of 1324312321 to array of integers in java this is fine. I could use integer parseint and string substring method but how do I repesent -12312312 to my original array of integer.. the fact that - is a char / string and convert to array of integer would alter the value ( even though I convert - to integer-equivalent , it would change the rest of 12312312) it must be an array of integers and how should I convert negative numbers and still keeep the same value somehow reminding me of two complements trick but i dont think i need to go down to binary level in my program.. any other trick for doing this? thanks!

• INSERT SQL in Java

  - by Pierre

  Hello. I have a Java application and I want to use SQL database. I have a class for my connection : public class SQLConnection{ private static String url = "jdbc:postgresql://localhost:5432/table"; private static String user = "postgres"; private static String passwd = "toto"; private static Connection connect; public static Connection getInstance(){ if(connect == null){ try { connect = DriverManager.getConnection(url, user, passwd); } catch (SQLException e) { JOptionPane.showMessageDialog(null, e.getMessage(), "Connection Error", JOptionPane.ERROR_MESSAGE); } } return connect; } } And now, in another class I succeeded to print my values but when I attempt to insert a value nothing is happening ... Here's my code : try { Statement state = SQLConnection.getInstance().createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY); Statement state2 = SQLConnection.getInstance().createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE); state2.executeUpdate("INSERT INTO table(field1) VALUES (\"Value\")"); // Here's my problem ResultSet res = state.executeQuery("SELECT * FROM plateau");

• Is there some way to assume @Nullable as default? (using FindBugs or any other free tool).

  - by alex2k8

  Consider such code public void m1(String text) { if(text == null) text = "<empty>"; System.out.println(text.toLowerCase()); } And this is a buggy version: public void m1(String text) { System.out.println(text.toLowerCase()); } If null value passed, the NullPointerException may be thrown. I would like the static-analysis tool (e.g. FindBugs) to report this issue. Unsuccessfully the FindBugs (at least by default) requires me to specify @Nullable annotation explicitly. public void m1(@Nullable String text) { System.out.println(text.toLowerCase()); // FindBugs: text must be nonnull but is marked as nullable } The problem is that if I forget to annotate it, the bug will be missed!!! How can I make the FindBugs (or any other free tool) to assume @Nullable by default?

• How can I apply indexer to Dictionary VALUES (C#3.0)

  - by Newbie

  I have done a program string[] arrExposureValues = stock.ExposureCollection[dt] .Values.ToArray(); for(int i=0;i<arrExposureValues .length;i++) Console.WriteLine(arrExposureValues[i]); Nothing wrong and works fine. But is it possible to do something like the below for(int i=0;i<stock.ExposureCollection[dt].Count;i++) Console.WriteLine(stock.ExposureCollection[dt].Values[i]); This is just for my sake of knowledge (Basically trying to accomplish the same in one line). Note: ExposureCollection is a dictionary object Dictionary<DateTime, Dictionary<string, string>> First of all I have the doubt if it is at all possible! I am using C#3.0. Thanks.

• Regex whitespace and special characters

  - by Sam R.

  I have this regular expression: [^\\s\"']+|\"([^\"]*)\"|'([^']*)' which works for splitting a string by white spaces, and anything within a quotation is not delimited. However, I notice that if I put in a string that starts with "" no matches are found. How would I correct this? For example, if I enter " test 2". I want it to match to [, test, 2] Note: using java to compile the regex, here is some code Pattern pattern = Pattern.compile("[^\\s\"']+|\"([^\"]*)\"|'([^']*)'"); Matcher matcher = pattern.matcher(SomeString); while (matcher.find()){ String temp = matcher.group(); //... Do something ... } Thanks.

• How to customize the Combobox dropdown list?

  - by lp

  I have created a Combo box using HIComboBoxCreate(). When I have a long string in the dropdown list, it goes beyond the screen and the starting of the string is not visible. I want the string to be truncated with ellipsis in such a case. I have looked into the ComboBox attributes but couldn't find any that I can use to set this. I'm ready to write some extra code to do this, but I'm not sure if it possible. Can someone please help?

• scala: how to rewrite this function using for comprehension

  - by opensas

  I have this piece of code with a couple of nasty nested checks... I'm pretty sure it can be rewritten with a nice for comprehension, but I'm a bit confused about how to mix the pattern matching stuff // first tries to find the token in a header: "authorization: ideas_token=xxxxx" // then tries to find the token in the querystring: "ideas_token=xxxxx" private def applicationTokenFromRequest(request: Request[AnyContent]): Option[String] = { val fromHeaders: Option[String] = request.headers.get("authorization") val tokenRegExp = """^\s*ideas_token\s*=\s*(\w+)\s*$""".r val tokenFromHeader: Option[String] = { if (fromHeaders.isDefined) { val header = fromHeaders.get if (tokenRegExp.pattern.matcher(header).matches) { val tokenRegExp(extracted) = header Some(extracted) } else { None } } else { None } } // try to find it in the queryString tokenFromHeader.orElse { request.queryString.get("ideas_token") } } any hint you can give me?

• Pass structured data from C++ app to ASP.NET web service.

  - by Odrade

  I have Visual C++ application that needs to communicate with a ASP.NET web service. Specifically, the app needs to pass structured data (e.g. objects that contain lists of structures, etc) as a parameter to one of the service methods. The C++ application is already generating an xml document that contains this data. The document is generating using an xml library, so it should always well-formed. What is a good method for passing this data to the web service? I'm thinking about passing the document to the web service as a string parameter, then deserializing to a .NET object based on an xsd. But, I hear that passing an xml doc as a string parameter is not recommended. So, my questions: What are the pitfalls associated with sending the document as a string parameter, assuming that the document itself is always well-formed? Assuming the above is a bad idea, what are some good alternate approaches?

• Overloading on return type ???

  - by Green Hyena

  scala> val shares = Map("Apple" -> 23, "MicroSoft" -> 50, "IBM" -> 17) shares: scala.collection.immutable.Map[java.lang.String,Int] = Map(Apple -> 23, MicroSoft -> 50, IBM -> 17) scala> val shareholders = shares map {_._1} shareholders: scala.collection.immutable.Iterable[java.lang.String] = List(Apple, MicroSoft, IBM) scala> val newShares = shares map {case(k, v) => (k, 1.5 * v)} newShares: scala.collection.immutable.Map[java.lang.String,Double] = Map(Apple -> 34.5, MicroSoft -> 75.0, IBM -> 25.5) From this example it seems like the map method is overloaded on return type. Overloading on return type is not possible right? Would somebody please explain what's going on here?

• PHP - Can you help change this function slightly?

  - by Joe

  I have the following function I modified based off someone elses function: function showCombinations($string, $nameString, $linkParts, $i){ $wordDivider = "/"; //the divider between the words/values if ($i >= count($linkParts)){ echo "<a href='".trim($string)."'>".trim($nameString)."</a>, "; } else { foreach ($linkParts[$i] as $currentTrait){ if ($currentTrait['name']=="urltext"){ $currentNameStringName=""; //ignore } else { $currentNameStringName=$currentTrait['name']; } if ($nameString!=""){ $currentNameString=$nameString." - ".$currentNameStringName; } else { $currentNameString=$nameString.$currentNameStringName; } showCombinations($string.$currentTrait['value'].$wordDivider, $currentNameString, $linkParts, $i + 1); } } } showCombinations('', '', $linkParts, 0); All I need to change this to do is, instead of "ECHO", I want it to build up the combination and so I can do: $result = showCombinations('', '', $linkParts, 0); echo $result; I need it this way because I have to modify that $result, not just echo it.

How can I make it ignore everything after the 2nd string?

• c++ Array passing dilemma

  - by Thomas

  Hi, I am writing a function that takes a string, string pointer and an int. The function splits the string based on a set of rules and puts each token into an array. I need to return the array out of the function with the number of elements in the int variable etc. I am stuck as to how I return the array as I can not use auto other wise it is destroyed and I am reluctant to use new as I feel this is patchy. I have other ideas on how to go about this but would like to see how other people go about this first. I could also be wrong and it could be possible to pass an auto out of an array. I can also not use vectors so there goes a copy constructor.

• only return random number when it is unique

  - by phil

  My brain is melting today and i cannot think how to do this simple bit of code. numberList is a string of numbers seperated by commas like '2, 34, 10' etc.. when i request a random number i need to check if the string has the number, if it does i want to keep requesting a random number until the random number is definitely not in the string. i cant think what kind of loop i would do to get this to work: Random r = new Random(); public int RandomPos(int max) { int i; do { i = r.Next(max) + 1; } while (!numberList.Contains(i.ToString())); return i; }
