  • how to read in a list of custom configuration objects

    - by Johnny
    hi, I want to implement Craig Andera's custom XML configuration handler in a slightly different scenario. What I want to be able to do is to read in a list of arbitrary length of custom objects defined as: public class TextFileInfo { public string Name { get; set; } public string TextFilePath { get; set; } public string XmlFilePath { get; set; } } I managed to replicate Craig's solution for one custom object but what if I want several? Craig's deserialization code is: public class XmlSerializerSectionHandler : IConfigurationSectionHandler { public object Create(object parent, object configContext, XmlNode section) { XPathNavigator nav = section.CreateNavigator(); string typename = (string)nav.Evaluate("string(@type)"); Type t = Type.GetType(typename); XmlSerializer ser = new XmlSerializer(t); return ser.Deserialize(new XmlNodeReader(section)); } } I think I could do this if I could get Type t = Type.GetType("System.Collections.Generic.List<TextFileInfo>") to work but it throws Could not load type 'System.Collections.Generic.List<Test1.TextFileInfo>' from assembly 'Test1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

  • Java Reflection, java.lang.IllegalAccessException Error

    - by rubby
    Hi all, My goal is : Third class will read the name of the class as String from console.Upon reading the name of the class, it will automatically and dynamically (!) generate that class and call its writeout method. If that class is not read from input, it will not be initialized. And I am taking java.lang.IllegalAccessException: Class deneme.class3 can not access a member of class java.lang.Object with modifiers "protected" error. And i don't know how i can fix it.. Can anyone help me? import java.io.*; import java.lang.reflect.*; class class3 { public void run() { try { BufferedReader reader= new BufferedReader(new InputStreamReader(System.in)); String line=reader.readLine(); Class c1 = Class.forName("java.lang.String"); Object obj = new Object(); Class c2 = obj.getClass(); Method writeout = null; for( Method mth : c2.getDeclaredMethods() ) { writeout = mth; break; } Object o = c2.newInstance(); writeout.invoke( o ); } catch(Exception ee) { System.out.println("ERROR!

  • How do you organise your MVC controller tests?

    - by Andrew Bullock
    I'm looking for tidy suggestions on how people organise their controller tests. For example, take the "add" functionality of my "Address" controller, [AcceptVerbs(HttpVerbs.Get)] public ActionResult Add() { var editAddress = new DTOEditAddress(); editAddress.Address = new Address(); editAddress.Countries = countryService.GetCountries(); return View("Add", editAddress); } [RequireRole(Role = Role.Write)] [AcceptVerbs(HttpVerbs.Post)] public ActionResult Add(FormCollection form) { // save code here } I might have a fixture called "when_adding_an_address", however there are two actions i need to test under this title... I don't want to call both actions in my Act() method in my fixture, so I divide the fixture in half, but then how do I name it? "When_adding_an_address_GET" and "When_adding_an_address_POST"? things just seems to be getting messy, quickly. Also, how do you deal with stateless/setupless assertions for controllers, and how do you arrange these wrt the above? for example: [Test] public void the_requesting_user_must_have_write_permissions_to_POST() { Assert.IsTrue(this.SubjectUnderTest.ActionIsProtectedByRole(c => c.Add(null), Role.Write)); } This is custom code i know, but you should get the idea, it simply checks that a filter attribute is present on the method. The point is it doesnt require any Arrange() or Act(). Any tips welcome! Thanks

  • Reading a Wordpress function description

    - by Casebash
    I want to be able to understand the standard function description that is provided for Wordpress functions. In particular, could someone explain the following example from here: Usage <?php wp_list_categories( $args ); ?> Default Usage <?php $args = array( 'show_option_all' => , 'orderby' => 'name', 'order' => 'ASC', 'show_last_update' => 0, 'style' => 'list', 'show_count' => 0, 'hide_empty' => 1, 'use_desc_for_title' => 1, 'child_of' => 0, 'feed' => , 'feed_type' => , 'feed_image' => , 'exclude' => , 'exclude_tree' => , 'include' => , 'current_category' => 0, 'hierarchical' => true, 'title_li' => __( 'Categories' ), 'number' => NULL, 'echo' => 1, 'depth' => 0 ); ?> I can guess most of it, but in particular I can't guess: What does blank after the comma mean? Empty string? What is the __? How do I call the function? Keyword like python, positional arguments or do I have to pass an array? Is there anything else about Wordpress function descriptions which isn't covered in this example? Thanks, Chris

  • How to Read Device Data From serial port

    - by Aamir Khurshid
    I have one device which sends data on COM port say on COM13. Now i want to read that data and display it in the RichTextBox or in any text control. I have written the application with the help of IO and IO.Ports but comport.DataRecived event does not fire, even though device is sending data on that port. I have some software on which i define the port number and it successfully display data, which insure me that data is receiving on the Port but i am unable to receive. Is there any way i can read data? comm.Parity = cboParity.Text;//None comm.StopBits = cboStop.Text;//One comm.DataBits = cboData.Text;//8 comm.BaudRate = cboBaud.Text;//9600 comm.DisplayWindow = rtbDisplay;//Null comm.PortName = "COM13"; comm.OpenPort(); cmdOpen.Enabled = false; cmdClose.Enabled = true; cmdSend.Enabled = true; public bool OpenPort() { if (comPort.IsOpen) { comPort.Close(); } comPort.DataReceived += new SerialDataReceivedEventHandler(comPort_DataReceived); comPort.PortName = _portName; comPort.Open();return true; }

  • XML Serializing a class with a Dictionary<string, List<string>> object

    - by Matt
    Is it possible to implement IXmlSerializable and in my XML file capture an object of type Dictionary ? I have the following public class coolio : IXmlSerializable { private int a; private bool b; private string c; private Dictionary<string, List<string>> coco; public coolio(int _a, bool _b, string _c, Dictionary<string, List<string>> _coco) { a=_a; b=_b; c=_c; coco=_coco; } public System.Xml.Schema.XmlSchema GetSchema() { return null; } public void WriteXml(XmlWriter writer) { const string myType = "coolio"; writer.WriteStartElement(myType); writer.WriteAttributeString("a", a.ToString()); writer.WriteAttributeString("b", b.ToString()); writer.WriteAttributeString("c", c); // How do I add a subelement for Dictionary<string, List<string>> coco? writer.WriteEndElement(); } public void ReadXml(XmlReader reader) { if (reader.MoveToContent() != XmlNodeType.Element || reader.LocalName != "coolio") return; a= int.Parse(reader["a"]); b = bool.Parse(reader["b"]); c= reader["c"]; // How do I read subelement into Dictionary<string, List<string>> coco? } } But I am stumped as to how I could add the Dictionary (XML seriliazed to my XML file)

  • Dynamically added JTable not displaying

    - by Graza
    Java Newbie here. I have a JFrame that I added to my netbeans project, and I've added the following method to it, which creates a JTable. Problem is, for some reason when I call this method, the JTable isn't displayed. Any suggestions? public void showFromVectors(Vector colNames, Vector data) { jt = new javax.swing.JTable(data, colNames); sp = new javax.swing.JScrollPane(jt); //NB: "this" refers to my class DBGridForm, which extends JFrame this.add(sp,java.awt.BorderLayout.CENTER); this.setSize(640,480); } The method is called in the following context: DBGridForm gf = new DBGridForm(); //DBGridForm extends JFrame DBReader.outMatchesTable(gf); gf.setVisible(true); ... where DBReader.outMatchesTable() is defined as static public void outMatchesTable(DBGridForm gf) { DBReader ddb = new DBReader(); ddb.readMatchesTable(null); gf.showFromVectors(ddb.lastRsltColNames, ddb.lastRsltData); } My guess is I'm overlooking something, either about the swing classes I'm using, or about Java. Any ideas?

  • Query column and everything subordinate (hard to describe, non native speaker, PLS let me explain)

    - by MAD9
    A few weeks ago, I asked a question about how to generate hierarchical XML from a table, that has a parentID column. It all works fine. The point is, according to the hierarchy, I also want to query a table. I'll give you an example: Thats the table with the codes: ID CODE NAME PARENTID 1 ROOT IndustryCode NULL 2 IND Industry 1 3 CON Consulting 1 4 FIN Finance 1 5 PHARM Pharmaceuticals 2 6 AUTO Automotive 2 7 STRAT Strategy 3 8 IMPL Implementation 3 9 CFIN Corporate Finance 4 10 CMRKT Capital Markets 9 From which I generate (for displaying in a TreeViewControl) this XML: <record key="1" parentkey="" Code="ROOT" Name="IndustryCode"> <record key="2" parentkey="1" Code="IND" Name="Industry"> <record key="5" parentkey="2" Code="PHARM" Name="Pharmaceuticals" /> <record key="6" parentkey="2" Code="AUTO" Name="Automotive" /> </record> <record key="3" parentkey="1" Code="CON" Name="Consulting"> <record key="7" parentkey="3" Code="STRAT" Name="Strategy" /> <record key="8" parentkey="3" Code="IMPL" Name="Implementation" /> </record> <record key="4" parentkey="1" Code="FIN" Name="Finance"> <record key="9" parentkey="4" Code="CFIN" Name="Corporate Finance"> <record key="10" parentkey="9" Code="CMRKT" Name="Capital Markets" /> </record> </record> </record> As you can see, some codes are subordinate to others, for example AUTO << IND << ROOT What I want (and have absolutely no idea how to realise or even, where to start) is to be able to query another table (where one column is this certain code of course) for a code and get all records with the specific code and all subordinate codes For example: I query the other table for "IndustryCode = IND[ustry]" and get (of course) the records containing "IND", but also AUTO[motive] and PHARM[aceutical] (= all subordinates) Its an SQL Express Server 2008 with Advanced Services.

  • Reading text files line by line, with exact offset/position reporting

    - by Benjamin Podszun
    Hi. My simple requirement: Reading a huge ( a million) line test file (For this example assume it's a CSV of some sorts) and keeping a reference to the beginning of that line for faster lookup in the future (read a line, starting at X). I tried the naive and easy way first, using a StreamWriter and accessing the underlying BaseStream.Position. Unfortunately that doesn't work as I intended: Given a file containing the following Foo Bar Baz Bla Fasel and this very simple code using (var sr = new StreamReader(@"C:\Temp\LineTest.txt")) { string line; long pos = sr.BaseStream.Position; while ((line = sr.ReadLine()) != null) { Console.Write("{0:d3} ", pos); Console.WriteLine(line); pos = sr.BaseStream.Position; } } the output is: 000 Foo 025 Bar 025 Baz 025 Bla 025 Fasel I can imagine that the stream is trying to be helpful/efficient and probably reads in (big) chunks whenever new data is necessary. For me this is bad.. The question, finally: Any way to get the (byte, char) offset while reading a file line by line without using a basic Stream and messing with \r \n \r\n and string encoding etc. manually? Not a big deal, really, I just don't like to build things that might exist already..

  • Stored Procedure Does Not Fire Last Command

    - by jp2code
    On our SQL Server (Version 10.0.1600), I have a stored procedure that I wrote. It is not throwing any errors, and it is returning the correct values after making the insert in the database. However, the last command spSendEventNotificationEmail (which sends out email notifications) is not being run. I can run the spSendEventNotificationEmail script manually using the same data, and the notifications show up, so I know it works. Is there something wrong with how I call it in my stored procedure?

  • ModelState always valid

    - by Jaimal Chohan
    I've got something seemingly very simple not working. I have got a model public class Name: Entity { [StringLength(10), Required] public virtual string Title { get; set; } } public class Customer: Entity { public virtual Name Name { get; set; } } a view model public class CustomerViweModel { public Customer Customer { get; set; } } a view <% using(Html.BeginForm()) { %> <%= Html.LabelFor(m => m.Customer.Name.Title)%> <button type="submit">Submit</button> <% } %> and a controller [HttpPost] public ActionResult Index([Bind(Prefix = "Customer")] Customer customer) { if(ModelState.IsValid) Save else return View(); } No matter what I enter as the title (null, or a string 10 chars), ModelState.IsValid is always true. The Title field in the Customer object has a value, so the data is being passed around, but not being validated? Any clues?

  • Execute Stored Procedure from Classic ASP

    - by Jaco Pretorius
    For some fantastic reason I find myself debugging a problem in a Classic ASP page (at least 10 years of my life lost in the last 2 days). I'm trying to execute a stored procedure which contains some OUT parameters. The problem is that one of the OUT parameters is not being populated when the stored procedure returns. I can execute the stored proc from SQL management studio (this is 2008) and all the values are being set and returned exactly as expected. declare @inVar1 varchar(255) declare @inVar2 varchar(255) declare @outVar1 varchar(255) declare @outVar2 varchar(255) SET @inVar2 = 'someValue' exec theStoredProc @inVar1 , @inVar2 , @outVar1 OUT, @outVar2 OUT print '@outVar1=' + @outVar1 print '@outVar2=' + @outVar2 Works great. Fantastic. Perfect. The exact values that I'm expecting are being returned and printed out. Right, since I'm trying to debug a Classic ASP page I copied the code into a VBScript file to try and narrow down the problem. Here is what I came up with: Set Conn = CreateObject("ADODB.Connection") Conn.Open "xxx" Set objCommandSec = CreateObject("ADODB.Command") objCommandSec.ActiveConnection = Conn objCommandSec.CommandType = 4 objCommandSec.CommandText = "theStoredProc " objCommandSec.Parameters.Refresh objCommandSec.Parameters(2) = "someValue" objCommandSec.Execute MsgBox(objCommandSec.Parameters(3)) Doesn't work. Not even a little bit. (Another ten years of my life down the drain) The third parameter is simply NULL - which is what I'm experiencing in the Classic ASP page as well. Could someone shed some light on this? Am I completely daft for thinking that the classic ASP code would be the same as the VBScript code? I think it's using the same scripting engine and syntax so I should be ok, but I'm not 100% sure. The result I'm seeing from my VBScript is the same as I'm seeing in ASP.

  • Failure remediation strategy for File I/O

    - by Brett
    I'm doing buffered IO into a file, both read and write. I'm using fopen(), fseeko(), standard ANSI C file I/O functions. In all cases, I'm writing to a standard local file on a disk. How often do these file I/O operations fail, and what should the strategy be for failures? I'm not exactly looking for stats, but I'm looking for a general purpose statement on how far I should go to handle error conditions. For instance, I think everyone recognizes that malloc() could and probably will fail someday on some user's machine and the developer should check for a NULL being returned, but there is no great remediation strategy since it probably means the system is out of memory. At least, this seems to be the approach taken with malloc() on desktop systems, embedded systems are different. Likewise, is it worth reattempting a file I/O operation, or should I just consider a failure to be basically unrecoverable, etc. I would appreciate some code samples demonstrating proper usage, or a library guide reference that indicates how this is to be handled. Any other data is, of course, welcome.

  • Choose a XML node in SQL Server based on max value of a child element

    - by Jay
    I am trying to select from SQL Server 2005 XML datatype some values based on the max data that is located in a child node. I have multiple rows with XML similar to the following stored in a field in SQL Server: <user> <name>Joe</name> <token> <id>ABC123</id> <endDate>2013-06-16 18:48:50.111</endDate> </token> <token> <id>XYX456</id> <endDate>2014-01-01 18:48:50.111</endDate> </token> </user> I want to perform a select from this XML column where it determines the max date within the token element and would return the datarows similar to the result below for each record: Joe XYZ456 2014-01-01 18:48:50.111 I have tried to find a max function for xpath that would all me to select the correct token element but I couldn't find one that would work. I also tried to use the SQL MAX function but I wasn't able to get it working with that method either. If I only have a single token it of course works fine but when I have more than one I get a NULL, most likely because the query doesn't know which date to pull. I was hoping there would be a way to specify a where clause [max(endDate)] on the token element but haven't found a way to do that. Here is an example of the one that works when I only have a single token: SELECT XMLCOL.query('user/name').value('.','NVARCHAR(20)') as name XMLCOL.query('user/token/id').value('.','NVARCHAR(20)') as id XMLCOL.query('user/token/endDate').value(,'xs:datetime(.)','DATETIME') as endDate FROM MYTABLE

  • Get the key and value of Map that is used Inside another Map (JAVA)

    - by Umair Iqbal
    I am using a map inside another map, The key of the outer map is Integer and the value is another Map. I get the values as expected but I don't know how to get the key and value of teh inner map. Here is the code Map<Integer, Map<Integer, Integer>> cellsMap = new HashMap<Integer, Map<Integer, Integer>>(); Map<Integer , Integer> bandForCell = cellsMap.get(band_number); if (bandForCell == null) bandForCell = new HashMap<Integer, Integer>(); bandForCell.put(erfcn, cell_found); cellsMap.put(band_number, bandForCell); csv.writeCells((Map<Integer, Map<Integer, Integer>>) cellsMap); public void writeCells (Map<Integer, Map<Integer, Integer>> cellsMap ) throws IOException { for (Map.Entry<Integer, Map<Integer, Integer>> entry : cellsMap.entrySet()) { System.out.println("Key: " + entry.getKey() + ". Value: " + entry.getValue() + "\n"); } } Out put of my Map Key: 20 Value: {6331=0, 6330=1, 6329=1, 6328=0, 6335=1, 6437=0, 6436=1} The value in the above output is another map. How can I get the key and value of the inner map from the value of the outer map? Like Keys of inner map = 6331, 6330, 6329 .... and values of inner map = 0 , 1 , 1 , 0 ... Thanks

  • parsing xml using dom4j

    My XML structure is like this: <rss> <channel> <yweather:location city="Paris" region="" country="France"/> <yweather:units temperature="C" distance="km" pressure="mb" speed="km/h"/> <yweather:wind chill="-1" direction="40" speed="11.27"/> <yweather:atmosphere humidity="87" visibility="9.99" pressure="1015.92" rising="0"/> <yweather:astronomy sunrise="8:30 am" sunset="4:54 pm"/> </channel> </rss> when I tried to parse it using dom4j SAXReader xmlReader = createXmlReader(); Document doc = null; doc = xmlReader.read( inputStream );//inputStream is input of function log.info(doc.valueOf("/rss/channel/yweather:location/@city")); private SAXReader createXmlReader() { Map<String,String> uris = new HashMap<String,String>(); uris.put( "yweather", "http://xml.weather.yahoo.com/ns/rss/1.0" ); uris.put( "geo", "http://www.w3.org/2003/01/geo/wgs84_pos#" ); DocumentFactory factory = new DocumentFactory(); factory.setXPathNamespaceURIs( uris ); SAXReader xmlReader = new SAXReader(); xmlReader.setDocumentFactory( factory ); return xmlReader; } But I got nothing in cmd but when I print doc.asXML(), my XML structure print correctly!

  • PHP cURL error: "Empty reply from server"

    - by ABach
    All, I have a class function to interface with the RESTful API for Last.FM - its purpose is to grab the most recent tracks for my user. Here it is: private static $base_url = 'http://ws.audioscrobbler.com/2.0/'; public static function getTopTracks($options = array()) { $options = array_merge(array( 'user' => 'bachya', 'period' => NULL, 'api_key' => 'xxxxx...', // obfuscated, obviously ), $options); $options['method'] = 'user.getTopTracks'; // Initialize cURL request and set parameters $ch = curl_init(); curl_setopt_array($ch, array( CURLOPT_URL => self::$base_url, CURLOPT_POST => TRUE, CURLOPT_POSTFIELDS => $options, CURLOPT_RETURNTRANSFER => TRUE, CURLOPT_TIMEOUT => 30, CURLOPT_USERAGENT => 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)' )); $results = curl_exec($ch); return $results; } This returns "Empty reply from server". I know that some have suggested that this error comes from some fault in network infrastructure; I do not believe this to be true in my case. If I run a cURL request through the command line, I get my data; the Last.FM service is up and accessible. Before I go to those folks and see if anything has changed, I wanted to check with you fine folks and see if there's some issue in my code that would be causing this. Thanks!

  • Linq Scope Problem + Reduce Repeated Code

    - by Tom Gullen
    If the parameter is -1, it needs to run a different query as to if an ID was specified... how do I do this? I've tried initialising var q; outside the If block but no luck! // Loads by Entry ID, or if -1, by latest entry private void LoadEntryByID(int EntryID) { IEnumerable<tblBlogEntry> q; if (EntryID == -1) { q = ( from Blog in db.tblBlogEntries orderby Blog.date descending select new { Blog.ID, Blog.title, Blog.entry, Blog.date, Blog.userID, Comments = ( from BlogComments in db.tblBlogComments where BlogComments.blogID == Blog.ID select BlogComments).Count(), Username = ( from Users in db.yaf_Users where Users.UserID == Blog.userID select new { Users.DisplayName }) }).FirstOrDefault(); } else { q = ( from Blog in db.tblBlogEntries where Blog.ID == EntryID select new { Blog.ID, Blog.title, Blog.entry, Blog.date, Blog.userID, Comments = ( from BlogComments in db.tblBlogComments where BlogComments.blogID == Blog.ID select BlogComments).Count(), Username = ( from Users in db.yaf_Users where Users.UserID == Blog.userID select new { Users.DisplayName }) }).SingleOrDefault(); } if (q == null) { this.Loaded = false; } else { this.ID = q.ID; this.Title = q.title; this.Entry = q.entry; this.Date = (DateTime)q.date; this.UserID = (int)q.userID; this.Loaded = true; this.AuthorUsername = q.Username; } } My main aim is to reduce repeating code

  • C# TCP socket with session

    - by Zé Carlos
    Is there any way of dealing with sessions with sockets in C#? Example of my problem: I have a server with a socket listening on port 5672. TcpListener socket = new TcpListener(localAddr, 5672); socket.Start(); Console.Write("Waiting for a connection... "); // Perform a blocking call to accept requests. TcpClient client = socket.AcceptTcpClient(); Console.WriteLine("Connected to client!"); And i have two clients that will send one byte. Client A send 0x1 and client B send 0x2. From the server side, i read this data like this: Byte[] bytes = new Byte[256]; String data = null; NetworkStream stream = client.GetStream(); while ((stream.Read(bytes, 0, bytes.Length)) != 0) { byte[] answer = new ... stream.Write(answer , 0, answer.Length); } Then client A sends 0x11. I need a way to know that this client is the same that sent "0x1" before.

  • Using SHFileOperation: What errors are occuring

    - by Sascha
    Hello I am using the function SHFileOperation() to send a file to the recycling bin. And I am getting 2 errors that I do not know what they mean because with this function the error codes are not GetLastError() values. Now when the function SHFileOperation() fails the return values are 0x57 (decimal 87) & 0x2 (decimal 2). Can you help me discover the definitions of these errors (expecially when you consider with this function, the errors are not part of the GetLastError() codes). Some important information: • I am using Windows 7 (& I know that MSDN says to use IFileOperation instead of SHFileOperation but I want to make my app backwards compatable which is why I am using SHFileOperation). If the error is occuring because I am using SHFileOperation on Windows 7 what solution could I use to make this work on all versions of windows from 2000 & up? • I have debugged extensively & as far as I know my SHFILEOPSTRUCT is correct (correct flags used, .pFrom is a double-null ended string). One thing I know for sure is that my path to the file is correct (leads to a real file & it correctly formatted). • About 2/5 times the SHFileOperation() works, meaning it sends the file to the recycle bin & does not returns an error BOOL result; SHFILEOPSTRUCT fileStruct; fileStruct.hwnd = hwnd; fileStruct.wFunc = FO_DELETE; fileStruct.pFrom = dest.c_str(); fileStruct.fFlags = FOF_FILESONLY; // FOF_ALLOWUNDO fileStruct.fAnyOperationsAborted = result; // Call operation(delete file) int success = SHFileOperation( &fileStruct ); // if delete was successful if ( success != 0 ) { printf( "%s \t %X %d \n", dest.c_str(), success, success ); cout << result << endl; MessageBox( hwnd, "Failed to delete file", "Error", MB_OK|MB_ICONERROR ); return; }
