  • How to bulk insert a CSV file into SQLite C#

    - by Lirik
    I have seen similar questions (1, 2), but none of them discuss how to insert CSV files into SQLite. About the only thing I could think of doing is to use a CSVDataAdapter and fill the SQLiteDataSet, then use the SQLiteDataSet to update the tables in the database: The only DataAdapter for CSV files I found is not actually available: CSVDataAdapter CSVda = new CSVDataAdapter(@"c:\MyFile.csv"); CSVda.HasHeaderRow = true; DataSet ds = new DataSet(); // <-- Use an SQLiteDataSet instead CSVda.Fill(ds); To write to a CSV file: CSVDataAdapter CSVda = new CSVDataAdapter(@"c:\MyFile.csv"); bool InclHeader = true; CSVda.Update(MyDataSet,"MyTable",InclHeader); I found the above code @ http://devintelligence.com/2005/02/dataadapter-for-csv-files/ The CSVDataAdapter was supposed to come with OpenNetCF's SDF, but it doesn't seem to be available anymore. Does anybody know where I can get a CSVDataAdapter? Perhaps somebody knows the much simpler thing: how to do bulk inserts of CSV files into SQLite... your help would be greatly appreciated!

  • xml parsing using nsxmlParser in iphone

    - by filthynight
    hi all, I have a problem in parsing xml from google api, the api xml looks like this ....... Now the problem is that first of all, the tags are different, like first parent tag name is "abc" and second parent tag is "efg", further more the inner tags are different as well. i have modified code got from web that it parses another url, but in this case since the tags keeps on changing it does not work. the url = "http://www.google.com/ig/api?weather=anaheim,ca" Source Code (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{ //NSLog(@"found this element: %@", elementName); if (currentElement) { [currentElement release]; currentElement = nil; } currentElement = [elementName copy]; NSString *thisOwner = [attributeDict objectForKey:@"data"]; NSLog(@"element Name-------: %@", thisOwner); if ([elementName isEqualToString:@"forecast_information"]) //|| [elementName isEqualToString:@"current_conditions"] || [elementName isEqualToString:@"forecast_conditions"]) { // clear out our story item caches... //NSString *nm = [[attributeDict objectForKey:@"city"] stringValue]; //NSLog(@"value...%@",nm); item = [[NSMutableDictionary alloc] init]; currentTitle = [[NSMutableString alloc] init]; currentDate = [[NSMutableString alloc] init]; currentSummary = [[NSMutableString alloc] init]; currentLink = [[NSMutableString alloc] init]; [item setObject:currentLink forKey:@"postal_code"]; [item setObject:currentSummary forKey:@"current_date_time"]; [item setObject:currentDate forKey:@"unit_system"]; NSLog(@"adding story: %@", currentTitle); [stories addObject:[item copy]]; } } I have another function didEndElement where the values are assigned in the array, but i could not figure out how to assign values of an attribute. Can somebody please help me in this regards Thanks!

  • Mixing Objective-C and C++

    - by helixed
    Hello, I'm trying to mix together some Objective-C code with C++. I've always heard it was possible, but I've never actually tried it before. When I try to compile the code, I get a bunch of errors. Here's a simple example I've created which illustrates my problems: AView.h #import <Cocoa/Cocoa.h> #include "B.h" @interface AView : NSView { B *b; } -(void) setB: (B *) theB; @end AView.m #import "AView.h" @implementation AView - (id)initWithFrame:(NSRect)frame { self = [super initWithFrame:frame]; if (self) { // Initialization code here. } return self; } - (void)drawRect:(NSRect)dirtyRect { // Drawing code here. } -(void) setB: (B *) theB { b = theB; } @end B.h #include <iostream> class B { B() { std::cout << "Hello from C++"; } }; Here's the list of errors I get when I try to compile this: /Users/helixed/Desktop/Example/B.h:1:0 /Users/helixed/Desktop/Example/B.h:1:20: error: iostream: No such file or directory /Users/helixed/Desktop/Example/B.h:3:0 /Users/helixed/Desktop/Example/B.h:3: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'B' /Users/helixed/Desktop/Example/AView.h:5:0 /Users/helixed/Desktop/Example/AView.h:5: error: expected specifier-qualifier-list before 'B' /Users/helixed/Desktop/Example/AView.h:8:0 /Users/helixed/Desktop/Example/AView.h:8: error: expected ')' before 'B' /Users/helixed/Desktop/Example/AView.m:26:0 /Users/helixed/Desktop/Example/AView.m:26: error: expected ')' before 'B' /Users/helixed/Desktop/Example/AView.m:27:0 /Users/helixed/Desktop/Example/AView.m:27: error: 'b' undeclared (first use in this function) All I'm doing to compile this right now is using the default compiler built into Xcode. I didn't edit the Cocoa Application template in any way other than adding the two files I created and chaing the NSView to AView in the xib file. Could somebody please tell me what I'm doing wrong?

  • Google Map API v3 — set bounds and center

    - by Michael Bradley
    Hi, I've recently switched to Google Maps API V3. I'm working of a simple example which plots markers from an array, however I do not know how to center and zoom automatically with respect to the markers. I've searched the net high and low, including Google's own documentation, but have not found a clear answer. I know I could simply take an average of the co-ordinates, but how would I set the zoom accordingly? Could somebody please point me in the right direction? Perhaps you know of a good tutorial. Many thanks in advance, Michael function initialize() { var myOptions = { zoom: 10, center: new google.maps.LatLng(-33.9, 151.2), mapTypeId: google.maps.MapTypeId.ROADMAP } var map = new google.maps.Map(document.getElementById("map_canvas"),myOptions); setMarkers(map, beaches); } var beaches = [ ['Bondi Beach', -33.890542, 151.274856, 4], ['Coogee Beach', -33.423036, 151.259052, 5], ['Cronulla Beach', -34.028249, 121.157507, 3], ['Manly Beach', -33.80010128657071, 151.28747820854187, 2], ['Maroubra Beach', -33.450198, 151.259302, 1] ]; function setMarkers(map, locations) { var image = new google.maps.MarkerImage('images/beachflag.png', new google.maps.Size(20, 32), new google.maps.Point(0,0), new google.maps.Point(0, 32)); var shadow = new google.maps.MarkerImage('images/beachflag_shadow.png', new google.maps.Size(37, 32), new google.maps.Point(0,0), new google.maps.Point(0, 32)); var lat = map.getCenter().lat(); var lng = map.getCenter().lng(); var shape = { coord: [1, 1, 1, 20, 18, 20, 18 , 1], type: 'poly' }; for (var i = 0; i < locations.length; i++) { var beach = locations[i]; var myLatLng = new google.maps.LatLng(beach[1], beach[2]); var marker = new google.maps.Marker({ position: myLatLng, map: map, shadow: shadow, icon: image, shape: shape, title: beach[0], zIndex: beach[3] }); } }

  • How to Unit Test HtmlHelper similar to using(Html.BeginForm()){ }

    - by DaveDev
    Can somebody please suggest how I could write a Unit Test with Moq for following HtmlHelper method? public static HtmlTagBase GenerateTag<T>(this HtmlHelper htmlHelper , object elementData , object attributes) where T : HtmlTagBase { return (T)Activator.CreateInstance(typeof(T) , htmlHelper.ViewContext , elementData , attributes); } which you would use as follows (please note the using statement - this is causing me confusion): <%--Model is a type of ShareClass--%> <% using (Html.GenerateTag<DivTag>(Model)) { %> My Div <% } %> using this method, if you specify T as type DivTag, where ShareClass is defined as public class ShareClass { public string Name { get; set; } public string Type { get; set; } public IEnumerable<Fund> Funds { get; set; } public ShareClass(string name, string shareClassType) { this.Name = name; this.Type = shareClassType; } } the following html will be rendered: <div class="ShareClass" shareclass-type="ShareClass_A" shareclass-name="MyShareClass">My Div</div>

  • c# How to Verify Signature, Loading PUBLIC KEY From PEM file?

    - by bbirtle
    I'm posting this in the hope it saves somebody else the hours I lost on this really stupid problem involving converting formats of public keys. If anybody sees a simpler solution or a problem, please let me know! The eCommerce system I'm using sends me some data along with a signature. They also give me their public key in .pem format. The .pem file looks like this: -----BEGIN PUBLIC KEY----- MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDe+hkicNP7ROHUssGNtHwiT2Ew HFrSk/qwrcq8v5metRtTTFPE/nmzSkRnTs3GMpi57rBdxBBJW5W9cpNyGUh0jNXc VrOSClpD5Ri2hER/GcNrxVRP7RlWOqB1C03q4QYmwjHZ+zlM4OUhCCAtSWflB4wC Ka1g88CjFwRw/PB9kwIDAQAB -----END PUBLIC KEY----- Here's the magic code to turn the above into an "RSACryptoServiceProvider" which is capable of verifying the signature. Uses the BouncyCastle library, since .NET apparently (and appallingly cannot do it without some major headaches involving certificate files): RSACryptoServiceProvider thingee; using (var reader = File.OpenText(@"c:\pemfile.pem")) { var x = new PemReader(reader); var y = (RsaKeyParameters)x.ReadObject(); thingee = (RSACryptoServiceProvider)RSACryptoServiceProvider.Create(); var pa = new RSAParameters(); pa.Modulus = y.Modulus.ToByteArray(); pa.Exponent = y.Exponent.ToByteArray(); thingee.ImportParameters(pa); } And then the code to actually verify the signature: var signature = ... //reads from the packet sent by the eCommerce system var data = ... //reads from the packet sent by the eCommerce system var sha = new SHA1CryptoServiceProvider(); byte[] hash = sha.ComputeHash(Encoding.ASCII.GetBytes(data)); byte[] bSignature = Convert.FromBase64String(signature); ///Verify signature, FINALLY: var hasValidSig = thingee.VerifyHash(hash, CryptoConfig.MapNameToOID("SHA1"), bSignature);

  • JSON-RPC and Json-rpc service discovery specifications

    - by Artyom
    Hello, I'm going to implement JSON-PRC web service. I need specifications for this. So far I had found only one resource that can be called as real specifications: JSON-RPC 1.0 http://json-rpc.org/wiki/specification Proposal of JSON-PRC 2.0: http://groups.google.com/group/json-rpc/web/json-rpc-2-0 (why is it on google groups?) However I've seen that JavaScript frameworks like Dojo actively use JSON-RPC SMD Service Mapping Description proposal But it requires JSON Schema specifications, but it redirects to incorrect URL as reference. So far I had found following: http://tools.ietf.org/html/draft-zyp-json-schema-02 And it is still draft... Can anybody point me to some actual specifications... At least something official updated? Because it looks like that implementing JSON-RPC 1.0 as is may be not enough, at least for frameworks like Dojo. Or am I wrong? Questions: Would implementation of JSON-RPC 1.0 specifications be enough to provide JSON-RPC service for most of modern clients, and how many clients there (if at-all) that actually support beyond JSON-RPC 1.0 capabilities (SMD, Schema, 2.0)? Because it looks like that JSON-RPC 1.0 is only one that has official specifications (and not draft) If I should implement SMD, or it is recommended can somebody point to official, most recent specifications of Json Schema and Service Mapping Description or links I found are really "the specifications?" Are JSON-RPC 2.0, SMD and JSON-Schema drafts stable enough to implement them? Note: do not suggest existing JSON-RPC service implementations. Anybody?

  • Invalid length for a Base-64 char array.

    - by Code Sherpa
    As the title says, I am getting: Invalid length for a Base-64 char array. I have read about this problem on here and it seems that the suggestion is to store ViewState in SQL if it is large. I am using a wizard with a good deal of data collection so chances are my ViewSate is large. But, before I turn to the "store-in-DB" solution, maybe somebody can take a look and tell me if I have other options? I construct the email for delivery using the below method: public void SendEmailAddressVerificationEmail(string userName, string to) { string msg = "Please click on the link below or paste it into a browser to verify your email account.<BR><BR>" + "<a href=\"" + _configuration.RootURL + "Accounts/VerifyEmail.aspx?a=" + userName.Encrypt("verify") + "\">" + _configuration.RootURL + "Accounts/VerifyEmail.aspx?a=" + userName.Encrypt("verify") + "</a>"; SendEmail(to, "", "", "Account created! Email verification required.", msg); } The Encrypt method looks like this: public static string Encrypt(string clearText, string Password) { byte[] clearBytes = System.Text.Encoding.Unicode.GetBytes(clearText); PasswordDeriveBytes pdb = new PasswordDeriveBytes(Password, new byte[] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 }); byte[] encryptedData = Encrypt(clearBytes, pdb.GetBytes(32), pdb.GetBytes(16)); return Convert.ToBase64String(encryptedData); } On the receiving end, the VerifyEmail.aspx.cs page has the line: string username = Cryptography.Decrypt(_webContext.UserNameToVerify, "verify"); And the decrypt method looks like: public static string Decrypt(string cipherText, string password) { **// THE ERROR IS THROWN HERE!!** byte[] cipherBytes = Convert.FromBase64String(cipherText); Can this error be remedied with a code fix or must I store ViewState in the database? Thanks in advance.

  • Filter Dynamically Calendar View SharePoint

    - by lerac
    Hello world I'm using SP wss 3.0 wondering if anybody knows how to filter a calendar view in SharePoint dynamically based upon the current user. It's not the simple question of using [ME] because this will not work with single line text fields. Also users do not add the items, they are being imported. So filtering on the basis of Created by, Modified by, Assigned to, or People picking data is not a option. Already managed to get to the current user in a jScript variable, now I would like to filter it in the calendar view. Been searching for a long time now, but can't seem to find anything. Altough filtering with a all items view is possible, yet I can't seem to find a way to dynamically filter a calendar view. Already tried modifing allitems.aspx view page in Designer Fooling around with CAML jScript (as far as I know) Calculated views Google (find more other cool things then a solution) Ofcourse I don't expect a solution on a silver platter (ofcourse would be nice ;) ), but if somebody can point me into a direction I already would be quite happy.

  • How can i handle a form submit using REAL OOP in PHP

    - by Lorence
    Im used to java and creating UML.. and i was wondering how can PHP be OOP, the objects live only until you make a request.. then they destroy, so if im using a database is useless to create a class and add the members (variables) to the class, they will be useless.. i cant pass the main system object from one page to another, or similar so how can PHP be compare to jave? you never do OOP .. i mean REAL OOP.. not creating classes , in fact your index will be a procedural file with some object instance and then ? how about if i make a html form and i want to submit the data.. i have to call a file which is not a class is a php procedural file were i grab the submited data with POST, from that file you will instance a class and do some logic there.. but for me thats not pure OOP.. can somebody point me to the right way of OOP using a form submit example ? Thanks!

  • What algorithms do "the big ones" use to cluster news?

    - by marco92w
    I want to cluster texts for a news website. At the moment I use this algorithm to find the related articles. But I found out that PHP's similar_text() gives very good results, too. What sort of algorithms do "the big ones", Google News, Topix, Techmeme, Wikio, Megite etc., use? Of course, you don't know exactly how the algorithms work. It's secret. But maybe someone knows approximately the way they work? The algorithm I use at the moment is very slow. It only compares two articles. So for having the relations between 5,000 articles you need about 12,500,000 comparisons. This is quite a lot. Are there alternatives to reduce the number of necessary comparisons? [I don't look for improvements for my algorithm.] What do "the big ones" do? I'm sure they don't always compare one article to another and this 12,500,000 times for 5,000 news. It would be great if somebody can say something about this topic.

  • Perl on MacOS X 10.6.2: GDBM_File missing, how to install or work around?

    - by jdmuys
    When I need a Perl module, I typically use CPAN. It works fine. But not this time. I want to use MARC::Charset, but this one uses GDBM_File, and I can't seem to install GDBM_File from CPAN. CPAN finds it all right, but trying to install it, it starts installing the full Perl 5.10.1 distribution. MARC::Charset is a rather old module, so there should be a way to use it from some common Perl version (Mac OS X 10.6.2 has 5.10.0 and 5.8.9 by default). While installing the full blow Perl 5.10.1 is not an option, modifying MARC::Charset to stop using GDBM_File might be one. What would be the best course of action to do so? This last option might also be the only one. googling GDBM_File uncovers a few items that suggest that gdbm is not even available on the Mac. Those items typically went over my head though. While I don't expect a silver bullet, somebody may have a pointer or two on where I should start. After all, MARC::Charset only does character transliteration to/from the marc8 char set, which unfortunately, iconv doesn't seem to support.

  • jQuery validation plugin and .ajax

    - by FALCONSEYE
    So, I have a form where I load divs as I go asking for various user input and displaying some offers. I have the following: $("#calcPrice").click(function() { $("#invPricing").validate({ rules: { ... }, messages: {... } , submitHandler: function(form) { .... $.ajax({ }); $.ajax({ }); return false; } }); My problem is after validation, none of the ajax calls work. If I remove the validation methods (rules, messages, submitHandler), everything works fine. Can somebody tell me what I am missing here? thanks in advance. btw, these are the ajax calls: $.ajax({ dataType: "json", type: "get", url: <cfoutput>"#actURL#"</cfoutput>, data: formData+"&p_type=LOW&returnJSON=true", cache: false, success: function(result) { // fields to populate: $("#rent").val(result.RENT); $("#discount").val(result.DISCOUNT); $("#salesPrice1").val(result.SALESPRICE); $("#cashPrice1").val(result.CASHSALESPRICE); $("#tax1").val(result.SALESTAX); $("#payment1").val(result.PAYMENTS); } , error: function(xmlHttpRequest, status, err) { confirm('Error!' + err); } }); $.ajax({ dataType: "json", type: "get", url: <cfoutput>"#actURL#"</cfoutput>, data: formData+"&p_type=HIGH&returnJSON=true", cache: false, success: function(result) { // fields to populate: $("#rent").val(result.RENT); $("#discount").val(result.DISCOUNT); $("#salesPrice2").val(result.SALESPRICE); $("#cashPrice2").val(result.CASHSALESPRICE); $("#tax2").val(result.SALESTAX); $("#payment2").val(result.PAYMENTS); } , error: function(xmlHttpRequest, status, err) { confirm('Error!' + err); } }); I am basically displaying two offers one Low, one High.

  • Mysql SELECT FOR UPDATE - strange issue

    - by Michal Fronczyk
    Hi, I have a strange issue (at least for me :)) with the MySQL's locking facility. I have a table: Create Table: CREATE TABLE test ( id int(11) NOT NULL AUTO_INCREMENT, PRIMARY KEY (id) ) ENGINE=InnoDB AUTO_INCREMENT=13 DEFAULT CHARSET=latin1 With this data: +----+ | id | +----+ | 3 | | 4 | | 5 | | 6 | | 7 | | 8 | | 10 | | 11 | | 12 | +----+ Now I have 2 clients with these commands executed at the beginning: set autocommit=0; set session transaction isolation level serializable; begin; Now the most interesting part. The first client executes this query: (makes an intent to insert a row with id equal to 9) SELECT * from test where id = 9 FOR UPDATE; Empty set (0.00 sec) Then the second client does the same: SELECT * from test where id = 9 FOR UPDATE; Empty set (0.00 sec) My question is: Why the second client does not block ? An exclusive gap lock should have been set by the first query because FOR UPDATE have been used and the second client should block. If I am wrong, could somebody tell me how to do it correctly ? The MySql version I use is: 5.1.37-1ubuntu5.1 Thanks, Michal

  • validate that URI is valid http URI

    - by Alfred
    Hi all, My problem: First of hopefully this is not a duplicate, but I could not find the right answer(right away). I would like to validate that an URI(http) is valid in Java. I came up with the following tests but I can't get them to pass. First I used getPort(), but then http://www.google.nl will return -1 on getPort(). This are the test I want to have passed Test: @Test public void testURI_Isvalid() throws Exception { assertFalse(HttpUtils.validateHTTP_URI("ttp://localhost:8080")); assertFalse(HttpUtils.validateHTTP_URI("ftp://localhost:8080")); assertFalse(HttpUtils.validateHTTP_URI("http://localhost:8a80")); assertTrue(HttpUtils.validateHTTP_URI("http://localhost:8080")); final String justWrong = "/schedule/get?uri=http://localhost:8080&time=1000000"; assertFalse(HttpUtils.validateHTTP_URI(justWrong)); assertTrue(HttpUtils.validateHTTP_URI("http://www.google.nl")); } This is what I came up with after I removed the getPort() part but this does not pass all my unit tests. Production code: public static boolean validateHTTP_URI(String uri) { final URI u; try { u = URI.create(uri); } catch (Exception e1) { return false; } return "http".equals(u.getScheme()); } This is the first test that is failing because I am no longer validating the getPort() part. Hopefully somebody can help me out. I think I am not using the right class to validate url's?? P.S: I don't want to connect to the server to validate the URI is correct. At least not yet in this step. I only want to validate scheme.

    - by BibiBuBu
    Good Day! i have a question that how can i use animation extender in datalist control in asp.net with c#. i want the animation when i click the delete button (delete button will be in repeater). so that when i remove one record then it shows animation to bring the next record. it is in update panel. <cc1:AnimationExtender ID="AnimationExtender1" runat="server" Enabled="True" TargetControlID="btnDeleteId"> <Animations> <OnClick> <Sequence> <EnableAction Enabled="false" /> <Parallel Duration=".2"> <Resize Height="0" Width="0" Unit="px" /> <FadeOut /> </Parallel> <HideAction /> </Sequence> </OnClick> </Animations> </cc1:AnimationExtender> now if i put my button id in the Target control id then it gives error that it should not be in same update panel etc... but over all nothing working for animation. i am binding my datalist in itemDataBound....e.g. ImageButton imgbtn = (ImageButton)e.Item.FindControl("imgBtnPic"); Label lblAvatar = (Label)e.Item.FindControl("lblAvatar"); LinkButton lbName = (LinkButton)e.Item.FindControl("lbtnName"); Can somebody please suggest me something. thanks

  • Moq for Silverlight doesn't raise event

    - by Budda
    Trying to write Unit test for Silverlight 4.0 using Moq 4.0.10531.7 public delegate void DataReceived(ObservableCollection<TeamPlayerData> AllReadyPlayers, GetSquadDataCompletedEventArgs squadDetails); public interface ISquadModel : IModelBase { void RequestData(int matchId, int teamId); void SaveData(); event DataReceived DataReceivedEvent; } void MyTest() { Mock<ISquadModel> mockSquadModel = new Mock<ISquadModel>(); mockSquadModel.Raise(model => model.DataReceivedEvent += null, EventArgs.Empty); } Instead of raising the 'DataReceivingEvent' the following error is received: Object of type 'Castle.Proxies.ISquadModelProxy' cannot be converted to type 'System.Collections.ObjectModel.ObservableCollection`1[TeamPlayerData]'. Why attempt to convert mock to the type of 1st event parameter is performed? How can I raise an event? I've also tried another approach: mockSquadModel .Setup(model => model.RequestData(TestMatchId, TestTeamId)) .Raises(model => model.DataReceivedEvent += null, EventArgs.Empty) ; this should raise event if case somebody calls 'Setup' method... Instead the same error is generated... Any thoughts are welcome. Thanks

  • Redirect on Ajax Jquery Call

    - by Mark Estrada
    Hi, I am newbie to ajax here and I know somebody would have encountered this problem already. I have a legacy app built on Spring MVC, it has a interceptor(filter) that redirects the user to the login page whenever there is no session. public class SessionCheckerInterceptor extends HandlerInterceptorAdapter { public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { HttpSession session = request.getSession(); // check if userInfo exist in session User user = (User) session.getAttribute("user"); if (user == null) { response.sendRedirect("login.htm"); return false; } return true; } } For non-xmlhttp request, this works fine.. but when I try to use ajax in my application, everything gets weird, it is not able to redirect to the login page correctly. As check the value of the xhr.status = 200 textStatus = parseError errorThrown = "Invalid JSON -Markup of my HTML Login Page- $(document).ready(function(){ jQuery.ajax({ type: "GET", url: "populateData.htm", dataType:"json", data:"userId=SampleUser", success:function(response){ //code here }, error: function(xhr, textStatus, errorThrown) { alert('Error! Status = ' + xhr.status); } }); }); I checked on my firebug that there is a 302 HTTP response but I am not sure how to catch the response and redirect the user to the login page. Any idea here? Thanks.

  • How to find cause and of the SocketException with message that an established connection was aborted

    - by cdpnet
    Hi All, I know the similar question may have been asked many times, but I want to represent the behavior I'm seeing and find if somebody can help predict the cause of this. I am writing a windows service which connects to other windows service over TCP. There are 100 user entities of this, and 5 connections per each. These users perform their tasks using their individual connections. The application goes on withough seeing this problem for 1 or 2 days. Or sometimes show the problem right after starting (-rarely). The best run I had was like 4 to 5 days without showing this exception. And after that application died or I had to stop it for various reasons. I want to know what can be causing this? Here is the stacktrace. System.IO.IOException: Unable to write data to the transport connection: An established connection was aborted by the software in your host machine. ---> System.Net.Sockets.SocketException: An established connection was aborted by the software in your host machine at System.Net.Sockets.Socket.Send(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.Write(Byte[] buffer, Int32 offset, Int32 size) --- End of inner exception stack trace --- at System.Net.Sockets.NetworkStream.Write(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Security._SslStream.StartWriting(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security._SslStream.ProcessWrite(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslStream.Write(Byte[] buffer, Int32 offset, Int32 count)

  • XML to Type - Quick way?

    - by MRFerocius
    Team; How are you doing? Im breaking my head trying to do this that seems simple but I can't figure it out... Suppose I have this XML as a string: <calles> <calle> <nombre>CALLAO AV.</nombre> <altura>1500</altura> <longitud>-58.3918617027</longitud> <latitud>-34.5916734896</latitud> <barrio>Recoleta</barrio> </calle> </calles> And and have this Type I created to map that XML: public class Ubicacion { public string Latitud { get; set; } public string Longitud { get; set; } public string Nombre { get; set; } public string Altura { get; set; } public string Barrio { get; set; } public Ubicacion() { } } I need to take that XML file and create an object with those values... Does somebody know a quick way to do it? with C#? I have been trying this but is not working at all... XElement dir = XElement.Parse(text); Ubicacion informacion = from d in dir.Elements("calle"). select new Ubicacion { Longitud = d.Element("longitud").Value, Latitud = d.Element("latitud").Value, Altura = d.Element("altura").Value, Nombre = d.Element("nombre").Value, Barrio = d.Element("barrio").Value, }; return informacion.Cast<Ubicacion>(); } Any ideas? Thanks!!!
