  • Display array values from web service method

    - by chupinette
    Hello all! I'm new to web services and im actually trying to learn how to develop one in C#. I have the following method in my web service which actually displays an array of int when i test it. [WebMethod] public int[] FindID(string str1,string str2) { Customer obj = new Customer(); obj.FindMatch(str1,str2); return obj.customer_id; } Now in my web application in which i have a button, the code is as below: Dim obj As localhost.Service = New localhost.Service Dim str1 As String = Session("str1") Dim str2 As String = Session("str2") Response.Write(obj.FindID(str1, str2)) The problem is that only the first value from the array is being displayed. Can anyone please help me to solve this problem?

  • Php/Regex get the contents between a set of double quotes

    - by Davy Arnold
    Update to my question: My goal overall is to split the string into 4 parts that I can access later. value = " result of the html inside the first and last " " Here is an example of what i'm trying to do: // My string (this is dynamic and will change, this is just an example) $string = 'value="<p>Some text</p> <a href="#">linky</a>"'; // Run the match and spit out the results preg_match_all('/([^"]*)(?:\s*=\s*(\042|\047))([^"]*)/is', $string , $results); // Here is the array I want to end up with Array ( [0] => Array ( [0] => value="<p>Some text</p><a href="#">linky</a>" ) [1] => Array ( [0] => value ) [2] => Array ( [0] => " ) [3] => Array ( [0] => <p>Some text</p><a href="#">linky</a> ) ) Basically the double quotes on the link are causing me some trouble so my first though was to do [^"]$ or something to have it just run until the last double quote, but that isn't getting me anywhere. Another idea I had was maybe process the string in PHP to strip out any inner quotes, but i'm not sure ho to go about this either. Hopefully I'm being clear, it is pretty late and i've been at this far too long!

  • LinQ: Add list to a list

    - by JohannesBoersma
    I have the following code: var columnNames = (from autoExport in dataContext.AutoExports where autoExport.AutoExportTemplate != null && ContainsColumn(autoExport.AutoExportTemplate, realName) select GetDbColumnNames(autoExport.AutoExportTemplate, realName)).ToList(); Where the function GetDbColumns() returns an List<string>. So columNames is of the type List<List<string>>. Is it possible to create a List<string>, so each element of the list of GetDbColumns is added to the result of the LinQ query?

  • Wildcards in T-SQL LIKE vs. ASP.net parameters

    - by Vinzcent
    In my SQL statement I use wildcards. But when I try to select something, it never select something. While when I execute the query in Microsoft SQL Server Management Studio, it works fine.

  • Ldap search query with parameters

    - by djerry
    Hey guys, I'm using a ldap server to store phonerecords. I want to select a record with a specific telnumber. So this is what I'm doing: LdapSearchResults lsc = _conn.Search(dnForPhonebook, 1, "(&(objectClass=*)(uid=" + id + "))", null, false); I'm using novell library for ldap commands. The options i need to give in for the Search command are the dn to the node "phonebook" (string), scope (int), filter (string), attrrs (string[]) and typesOnly (bool). As you can see, for the filter, i'm pasting the parameter as string in de stringfilter. I was wondering, does ldap have the same way of work as mysql or sql server, which can work with paramaters? Thanks in advance.

  • Cant run application (C#) through cmd

    - by user301639
    Hey, I cant execute application through cmd, when the application trying to read the argument which was sent to it (text file), it fails... when i'm truing to execute it through the IDE (vs2008), it works ok... that's what i did in the main method : static void Main(string[] args) { int choice = 0; if (args.Length == 0) choice = 1; else choice = 2; switch(choice) { case 1: { string[] text = Directory.GetFiles("allText"); Console.WriteLine(DateTime.Now.ToString()); foreach (string fileName in text) { string substring = fileName.Substring(8); ReadData_Logic rd_l = new ReadData_Logic(substring); rd_l.runThreadsAndDecrypt(); rd_l.printKey(substring.Substring(0, fileName.Length - 15).Insert(0, "encryptedKey\\") + "_result.txt"); } Console.WriteLine(DateTime.Now.ToString()); } break; case 2: { Console.WriteLine(DateTime.Now.ToString()); string fileName = args[0]; Console.WriteLine(fileName); **<--- for debug, here i do see the correct file name** ReadData_Logic rd_l = new ReadData_Logic(fileName); rd_l.runThreadsAndDecrypt(); rd_l.printKey(fileName + "_result.txt"); Console.WriteLine(DateTime.Now.ToString()); } break; } } what wrong with the code ? thanks

    Hi, I am trying to fill object[] with List<string> but I cannot figure out how to use ConvertAll. MSDN did not help me. At first I tried to create an instance of Converter but it looks like it expects delegate?

  • Using JAXB to customise the generation of java enums

    - by belltower
    I'm using an external bindings file when using jaxb against an XML schema. I'm mostly using the bindings file to map from the XML schema primitives to my own types. This is a snippet of the bindings file <jxb:bindings version="1.0" xmlns:jxb="http://java.sun.com/xml/ns/jaxb" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:ai="http://java.sun.com/xml/ns/jaxb/xjc" extensionBindingPrefixes="ai"> <jxb:bindings schemaLocation="xsdurl" node="xs:schema"> <jxb:globalBindings> <jxb:javaType name="com.companyname.StringType" xmlType="xs:string" parseMethod="parse" printMethod="print" hasNsContext="true"> </jxb:javaType> </jxb:globalBindings> </jxb:bindings> </jxb:bindings> So whenever a xs:string is encountered, the com.companyname.StringType the methods print / parse are called for marshalling/unmarshalling etc. Now if JAXB encounters an xs:enumeration it will generate a java enum. For example: <xs:simpleType name="Address"> <xs:restriction base="xs:string"> <xs:enumeration value="ADDR"/> <xs:enumeration value="PBOX"/> </xs:restriction> </xs:simpleType> public enum Address { ADDR, PBOX, public String value() { return name(); } public static Address fromValue(String v) { return valueOf(v); } } Does anyone know if it is possible to customise the creation of an enum like it is for a primitive? I would like to be able to: Add a standard member variable / other methods to every enum generated by jaxb. Specify the static method used to create the enum.

  • Android Multiple objects in SimpleAdapter

  • How can I inherit an ASP.NET MVC controller and change only the view?

    - by AlexWalker
    I have a controller that's inheriting from a base controller, and I'm wondering how I can utilize all of the logic from the base controller, but return a different view than the base controller uses. The base controller populates a model object and passes that model object to its view, but I'm not sure how I can access that model object in the child controller so that I can pass it to the child controller's view.

  • Cleaning up a dynamic array of Objects in C++

    - by Dr. Monkey
    I'm a bit confused about handling an array of objects in C++, as I can't seem to find information about how they are passed around (reference or value) and how they are stored in an array. I would expect an array of objects to be an array of pointers to that object type, but I haven't found this written anywhere. Would they be pointers, or would the objects themselves be laid out in memory in an array? In the example below, a custom class myClass holds a string (would this make it of variable size, or does the string object hold a pointer to a string and therefore take up a consistent amount of space. I try to create a dynamic array of myClass objects within a myContainer. In the myContainer.addObject() method I attempt to make a bigger array, copy all the objects into it along with a new object, then delete the old one. I'm not at all confident that I'm cleaning up my memory properly with my destructors - what improvements could I make in this area? class myClass { private string myName; public unsigned short myAmount; myClass(string name, unsigned short amount) { myName = name; myAmount = amount; } //Do I need a destructor here? I don't think so because I don't do any // dynamic memory allocation within this class } class myContainer { int numObjects; myClass * myObjects; myContainer() { numObjects = 0; } ~myContainer() { //Is this sufficient? //Or do I need to iterate through myObjects and delete each // individually? delete [] myObjects; } void addObject(string name, unsigned short amount) { myClass newObject = new myClass(name, amount); myClass * tempObjects; tempObjects = new myClass[numObjects+1]; for (int i=0; i<numObjects; i++) tempObjects[i] = myObjects[i]); tempObjects[numObjects] = newObject; numObjects++; delete newObject; //Will this delete all my objects? I think it won't. //I'm just trying to delete the old array, and have the new array hold // all the objects plus the new object. delete [] myObjects; myObjects = tempObjects; } }

  • Strange Values in SYS.DM_TRAN_LOCKS table RESOURCE_ASSOCIATED_ENTITY_ID column

    - by AJM
    I’ve been trying to understand some strange values in the RESOURCE_ASSOCIATED_ENTITY_ID column of SYS.DM_TRAN_LOCKS when RESOURCE_TYPE is “OBJECT”. Although these should be object Ids, I cannot determine what object they actually refer to. I’ve tried everything I can think of, including querying all system tables with columns of type INT and BIGINT to see if I can find the value. No luck. The funny values actually appear in SYS.DM_TRAN_LOCKS, SYS.SYSLOCKINFO and SP_LOCK.

  • How to convert model into url properly in asp.net MVC?

    - by 4eburek
    From the SEO standpoint it is nice to see urls in format which explains what is located on a page Let's have a look on such situation (it is just example) We need to display page about some user and decided to have such url template for that page: /user/{UserId}/{UserCountry}/{UserLogin}. And create for this purpose such model public class UserUrlInfo{ public int UserId{get;set;} public string UserCountry{get;set;} public string UserLogin{get;set;} } I want to create controller method where I pass UserUrlInfo object but not all required fields. Classic controller method for url template shown above is following public ActionResult Index(int UserId, string UserCountry, string UserLogin){ return View(); } and we need to call it like that Html.ActionLink<UserController>(x=>Index(user.UserId, user.UserCountry, user.UserLogin), "See user page") I want to create such controller method public ActionResult Index(UserUrlInfo userInfo){ return View(); } and call it like that: Html.ActionLink<UserController>(x=>Index(user), "See user page") Actually I works when we add one more route and point it to the same controller method, so routing will be: /user/{userInfo} /user/{UserId}/{UserCountry}/{UserLogin} In this situation routing engine gets string method of our model (need to override it) and it works ALMOST always. But sometimes it fails and show url like /page/?userInfo=/US/John So my workaround does not always work properly. Does anybody know how to work with urls in such way?

  • Adroid's DateFormat replacement - missing the format() with FieldPosition

    - by user331244
    Hi, I need to split a date string into pieces and I'm doing it using the public final StringBuffer format (Object object, StringBuffer buffer, FieldPosition field) from the java.text.DateFormat class. However, the implementation of this function is really slow, hence Android has an own implementation in android.text.format.DateFormat. BUT, in my case, I want to extract the different pieces of the date string (year, minute and so on). Since I need to be locale independent, I can not use SimpleDateFormat and custom strings. I do it as follows: Calendar c = ... // find out what field to extract int field = getField(); // Create a date string Field calendarField = DateFormat.Field.ofCalendarField(field); FieldPosition fieldPosition = new FieldPosition(calendarField); StringBuffer label = new StringBuffer(); label = getDateFormat().format(c.getTime(), label, fieldPosition); // Find the piece that we are looking for int beginIndex = fieldPosition.getBeginIndex(); int endIndex = fieldPosition.getEndIndex(); String asString = label.substring(beginIndex, endIndex); For some reason, the format() overload with the FieldPosition argument is not included in the android platform. Any ideas of how to do this in another way? Is there any easy way to tokenize the pattern string? Any other ideas?

  • Strange problem with Google App Engine Java Mail

    - by Velu
    Hi, I'm using the MailService feature of Google App Engine in my application. It works fine in one application without any issues. But the same code doesn't work in another app. I'm not able to figure it out. Please help. Following is the piece of code that I use to send mail. public static void sendHTMLEmail(String from, String fromName, String to, String toName, String subject, String body) { _logger.info("entering ..."); Properties props = new Properties(); Session session = Session.getDefaultInstance(props, null); _logger.info("got mail session ..."); String htmlBody = body; try { Message msg = new MimeMessage(session); _logger.info("created mimemessage ..."); msg.setFrom(new InternetAddress(from, fromName)); _logger.info("from is set ..."); msg.addRecipient(Message.RecipientType.TO, new InternetAddress( to, toName)); _logger.info("recipient is set ..."); msg.setSubject(subject); _logger.info("subject is set ..."); Multipart mp = new MimeMultipart(); MimeBodyPart htmlPart = new MimeBodyPart(); htmlPart.setContent(htmlBody, "text/html"); mp.addBodyPart(htmlPart); _logger.info("body part added ..."); msg.setContent(mp); _logger.info("content is set ..."); Transport.send(msg); _logger.info("email sent successfully."); } catch (AddressException e) { e.printStackTrace(); } catch (MessagingException e) { e.printStackTrace(); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); System.err.println(e.getMessage()); } } When I look at the log (on the server admin console), it prints the statement "content is set ..." and after that there is nothing in the log. The mail is not sent. At times I get the following error after the above statement is printed (and the mail is not sent). com.google.appengine.repackaged.com.google.common.base.internal.Finalizer getInheritableThreadLocalsField: Couldn't access Thread.inheritableThreadLocals. Reference finalizer threads will inherit thread local values. But the mail quota usage keeps increasing. Remember, this works fine in one application, but not in other. I'm using the same set of email addresses in both the apps (for from and to). I'm really stuck with this. Appreciate any help. Thank you. Velu

  • Is there a standard Cyclic Iterator in C++

    - by Hippicoder
    Based on the following question: Check if one string is a rotation of other string I was thinking of making a cyclic iterator type that takes a range, and would be able to solve the above problem like so: std::string s1 = "abc" ; std::string s2 = "bca" ; std::size_t n = 2; // number of cycles cyclic_iterator it(s2.begin(),s2.end(),n); cyclic_iterator end; if (std::search(it, end, s1.begin(),s1.end()) != end) { std::cout << "s1 is a rotation of s2" << std::endl; } My question, Is there already something like this available? I've check Boost and STL doesn't have one. I've got a simple hand-written one but would rather use an already made/tested implementation.

  • Having Issue with Bounded Wildcards in Generic

    - by Sanjiv
    I am new to Java Generics, and I'm currently experimenting with Generic Coding....final goal is to convert old Non-Generic legacy code to generic one... I have defined two Classes with IS-A i.e. one is sub-class of other. public class Parent { private String name; public Parent(String name) { super(); this.name = name; } } public class Child extends Parent{ private String address; public Child(String name, String address) { super(name); this.address = address; } } Now, I am trying to create a list with bounded Wildcard. and getting Compiler Error. List<? extends Parent> myList = new ArrayList<Child>(); myList.add(new Parent("name")); // compiler-error myList.add(new Child("name", "address")); // compiler-error myList.add(new Child("name", "address")); // compiler-error Bit confused. please help me on whats wrong with this ?

  • Why is a NullReferenceException thrown when a ToolStrip button is clicked twice with code in the `Click` event handler?

    - by Patrick
    I created a clean WindowsFormsApplication solution, added a ToolStrip to the main form, and placed one button on it. I've added also an OpenFileDialog, so that the Click event of the ToolStripButton looks like the following: private void toolStripButton1_Click(object sender, EventArgs e) { openFileDialog1.ShowDialog(); } I didn't change any other properties or events. The funny thing is that when I double-click the ToolStripButton (the second click must be quite fast, before the dialog opens), then cancel both dialogs (or choose a file, it doesn't really matter) and then click in the client area of main form, a NullReferenceException crashes the application (error details attached at the end of the post). Please note that the Click event is implemented while DoubleClick is not. What's even more strange that when the OpenFileDialog is replaced by any user-implemented form, the ToolStripButton blocks from being clicked twice. I'm using VS2008 with .NET3.5. I didn't change many options in VS (only fontsize, workspace folder and line numbering). Does anyone know how to solve this? It is 100% replicable on my machine, is it on others too? One solution that I can think of is disabling the button before calling OpenFileDialog.ShowDialog() and then enabling the button back (but it's not nice). Any other ideas? And now the promised error details: System.NullReferenceException was unhandled Message="Object reference not set to an instance of an object."

  • Improve a haskell script

    - by Hector Villalobos
    I'm a newbie in Haskell and I'd like some opinions about improving this script. This is a code generator and requires a command line argument to generate the sql script. ./GenCode "people name:string age:integer" Code: import Data.List import System.Environment (getArgs) create_table :: String -> String create_table str = "CREATE TABLE " ++ h (words str) where h (x:xs) = let cab = x final = xs in x ++ "( " ++ create_fields xs ++ ")" create_fields (x:xs) = takeWhile (/=':') x ++ type x ++ sig where sig | length xs > 0 = "," ++ create_fields xs | otherwise = " " ++ create_fields xs create_fields [] = "" type x | isInfixOf "string" x = " CHARACTER VARYING" | isInfixOf "integer" x = " INTEGER" | isInfixOf "date" x = " DATE" | isInfixOf "serial" x = " SERIAL" | otherwise = "" main = mainWith where mainWith = do args <- getArgs case args of [] -> putStrLn $ "You need one argument" (x:xs) -> putStrLn $ (create_table x)
