  • Java mail encoding

    - by Argiropoulos Stavros
    Using the code below i can send an email written in non-english and although the subject appears correctly the body appears as gibberish. Any ideas? Thank you public void postMail(String recipient, String subject, String message, String from) throws MessagingException, UnsupportedEncodingException { //Set the host smtp address Properties props = new Properties(); props.put("mail.smtp.host", "mail.infodim.gr"); // create some properties and get the default Session Session session = Session.getDefaultInstance(props, null); // create a message Message msg = new MimeMessage(session); // set the from and to address InternetAddress addressFrom = new InternetAddress(from); msg.setFrom(addressFrom); InternetAddress addressTo=new InternetAddress(recipient); msg.setRecipient(Message.RecipientType.TO, addressTo); // Setting the Subject and Content Type msg.setSubject(subject); msg.setContent(message, "text/plain"); Transport.send(msg); }

  • Java parsing UTF8

    - by Jack
    I have the following issue with a UTF8 files structured as following: FIELD1§FIELD2§FIELD3§FIELD4 Looking at hexadecimal values of the file it uses A7 to codify §. So according to this codify it should be UTF8, but it's strange because A7 7F so 1 byte shouldn't be enough to codify §. So I tried using directly a BufferedReader with a specified charset: BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(input), utf8)) but when I try to tokenize the string with SmartTokenizer st = new SmartTokenizer(toTokenize, "§") (the SmartTokenizer is a modified version of the StringTokenizer that keeps empty tokens) no splitting occurs, and if I try to print the string I obtain FIELD1?FIELD2?FIELD3?... so § used in the file is different from the one specified as a the delimiter, and it's not able to print out it too. So what's the problem here? Maybe the original file should use 2 bytes to store §?

  • Google Maps Rollover Problem in a Flex Website

    - by Laxmidi
    Hi, I'm using Google Maps in my Flex site to create a map. I've got polygons overlayed on the map. When the user rolls over a polygon an infowindow opens identifying the area and the fill Alpha of the area is set to 0. On roll-out, the info window is removed and the fill Alpha is returned to the default, 0.2. The polygons display and the InfoWindow is added and removed correctly. The problem is that the change in fill alpha only occurs on the very last polygon in the list. So for example, if I have polygons A, B, C, and D. If I rollover A, then A's alpha should change. But, instead D's alpha changes. No matter which polygon I rollover, the last polygon's alpha changes. It's weird, because the infoWindows behave correctly on rollover. So, if I rollover polygon A, the correct information for InfoWindow A appears. Please see the code below: private function allEncodedPolygons(event:MouseEvent) : void { var myPaneManager:IPaneManager = map.getPaneManager(); var myMapPane:IPane = myPaneManager.createPane(); if (allHoodsToggle.selected) { map.clearOverlays(); mapType.selectedIndex = -1; for each (var neighbNode:XML in detailMapResultData){ outlinePolygon = this.createPoly(neighbNode); map.addOverlay(outlinePolygon)}; allHoodsToggle.removeEventListener(MouseEvent.CLICK, allEncodedPolygons); } else {myPaneManager.clearOverlays(); allHoodsToggle.removeEventListener(MouseEvent.CLICK, allEncodedPolygons); } } The function below creates the polygons and has the rollover function: private var neighbShapes:Polygon; private function createPoly(neighbNode:XML):Polygon { var optionsDefault:PolygonOptions = new PolygonOptions( { strokeStyle: {thickness: 5, color: 0xFFFF00, alpha: 0.4, pixelHinting: true}, fillStyle: { alpha: 0.2 }} ); var neighbCenterLat:Number = neighbNode.latitudeCenter.toString(); var neighbCenterLong:Number = neighbNode.longitudeCenter.toString(); var neighbCenter:LatLng = new LatLng(neighbCenterLat,neighbCenterLong); var optionsHover:PolygonOptions = new PolygonOptions( { fillStyle: { alpha: 0.0 }} ); var encodedData:EncodedPolylineData = new EncodedPolylineData(neighbNode.encoding.toString(), neighbNode.zoomFactor.toString(), neighbNode.level.toString(), neighbNode.numlevels.toString()); var encodedList:Array = [encodedData]; neighbShapes = Polygon.fromEncoded(encodedList, optionsDefault); neighbShapes.addEventListener(MapMouseEvent.CLICK, function(event:MapMouseEvent): void { map.openInfoWindow(event.latLng, new InfoWindowOptions({content: neighbNode.name.toString(), hasCloseButton:false, hasShadow:true})); }); neighbShapes.addEventListener(MapMouseEvent.ROLL_OVER, function(event:MapMouseEvent): void { neighbShapes.setOptions(optionsHover); map.openInfoWindow(neighbCenter, new InfoWindowOptions({content: neighbNode.name.toString(), hasCloseButton:false, hasShadow:false})); }); neighbShapes.addEventListener(MapMouseEvent.ROLL_OUT, function(event:MapMouseEvent): void { neighbShapes.setOptions(optionsDefault); }); return neighbShapes; } Any suggestions as to why the function that changes the alpha is firing on the last polygon only, even though the InfoWindow appears correctly? If anyone has any ideas, I'd love to hear them. Thanks. -Laxmidi

  • C# XMLSerializer fails with List<T>

    - by Redshirt
    Help... I'm using a singleton class to save all my settings info. It's first utilized by calling Settings.ValidateSettings(@"C:\MyApp") The problem I'm having is that 'List Contacts' is causing the xmlserializer to fail to write the settings file, or to load said settings.

  • Unit test for Web Forms MVP presenter has a null Model

    - by jacksonakj
    I am using Web Forms MVP to write an DotNetNuke user control. When the 'SubmitContactUs' event is raised in my unit test the presenter attempts to set the 'Message' property on the Modal. However the View.Modal is null in the presenter. Shouldn't the Web Forms MVP framework automatically build a new View.Model object in the presenter? It could be that the 'Arrange' portion of my test is missing something that the presenter needs. Any help would be appreciated. Here is my test: using System; using AthleticHost.ContactUs.Core.Presenters; using AthleticHost.ContactUs.Core.Views; using Xunit; using Moq; namespace AthleticHost.ContactUs.Tests { public class ContactUsPresenterTests { [Fact] public void ContactUsPresenter_Sets_Message_OnSubmit() { // Arrange var view = new Mock<IContactUsView>(); var presenter = new ContactUsPresenter(view.Object); // Act view.Raise(v => v.Load += null, new EventArgs()); view.Raise(v => v.SubmitContactUs += null, new SubmitContactUsEventArgs("Chester", "Tester", "[email protected]", "http://www.test.com", "This is a test of the emergancy broadcast system...")); presenter.ReleaseView(); // Assert Assert.Contains("Chester Tester", view.Object.Model.Message); } } }

  • SQL Server: Can INFORMATION_SCHEMA Tell Me When a SQL Object Was Created?

    - by Jim G.
    Given: I added a non-nullable foreign key to a table. I settled on a way to populate the foreign key with default values. I checked in both changes to a re-runnable DB creation script. Other developers ran this script, and now they have the foreign key populated with default values on their developer machines. A few days later however... I changed my mind. Now I'd like to populate the foreign key's default values differently. My Question: Can SQL Server or INFORMATION_SCHEMA tell me when SQL objects were created? Ideally, I'd like to drop and re-add the foreign key if it was created before a certain date/time. Any help or alternative strategies would be greatly appreciated. Obviously, I'd like to avoid going to each developer's cube, asking them to drop the foreign key manually.

  • What can I expect as the core stack for Rails 3.0 and what will I need to include now as a plugin

    - by DJTripleThreat
    So Rails and Merb are sort of merging in Rails 3.0? Thats how its been described to me anyway. This means that a lot of what made Rails, Rails will now be moved to plug-ins so that it can be more lightweight. HOwever, what are those plug-ins going to be and as a new Rails developer, what are THE must have - and also more mature - plug-ins that a Rails developer should install? Some good examples I can think of might be will_paginate, ruby_prof or sqlite3-ruby.

  • Designer serialization persistence problem in .NET, Windows Forms

    - by Jules
    ETA: I have a similar, smaller, problem here which, I suspect, is related to this problem. I have a class which has a readonly property that holds a collection of components (* not quite, see below). At design time, it's possible to select from the components on the design surface to add to the collection. (Think imagelist, but instead of selecting one, you can select as many as you want.) As a test, I inherit from button and attach my class to it as a property. The persistence problem occurs when I add a component,to the collection, from the design surface after I have added my button to the form. The best way to demonstrate this is to show you the designer generated code: Private Sub InitializeComponent() Dim Provider1 As WindowsApplication1.Provider = New WindowsApplication1.Provider Me.MyComponent2 = New WindowsApplication1.MyComponent Me.MyComponent1 = New WindowsApplication1.MyComponent Me.MyButton1 = New WindowsApplication1.MyButton Me.MyComponent3 = New WindowsApplication1.MyComponent Me.SuspendLayout() ' 'MyButton1 ' Me.MyButton1.ProviderCollection.Add(Me.MyButton1.InternalProvider) Me.MyButton1.ProviderCollection.Add(Me.MyComponent1.Provider) Me.MyButton1.ProviderCollection.Add(Me.MyComponent2.Provider) Me.MyButton1.ProviderCollection.Add(Provider1) //Wrong should be Me.MyComponent3.Provider ' 'Form1 ' Me.Controls.Add(Me.MyButton1) End Sub Friend WithEvents MyComponent1 As WindowsApplication1.MyComponent Friend WithEvents MyComponent2 As WindowsApplication1.MyComponent Friend WithEvents MyButton1 As WindowsApplication1.MyButton Friend WithEvents MyComponent3 As WindowsApplication1.MyComponent End Class As you can see from the code, the collection is not actually a collection of the components, but a collection of a property, 'Provider', from the components. It looks like the problem is occurring because MyComponent3 is created after MyButton. However, in my opinion, this should not make any difference - by the time the serializer comes to add the provider property of MyComponent3, it's already created. Note: You may wonder, why I'm not using AddRange to persist the collection. The reason for this is that if I do, the behaviour changes and none of the items will persist correctly. The designer will create local fields - like Provider1 - for each item in the collection. However if I add another collection to the class which holds the actual MyComponents and persist this, then, somehow, the AddRange method persists correctly in ProviderCollection! There seems to be some kind of quantum double slit experiment going down in code dom. How can I solve this problem?

    Hi, everyone I am using BlazeDS for data-push feature in my Flex application project. From the official tutorial, Getting started with BlazeDS, it shows messaging example with producer/consumer from API. but how can I implement server side which doesn't need to be invoke from Flex client, but from within server-side instead. I got some idea but I don't know how to do because I'm a Flex developer, not Java developer, so I think you can help me. In Google, there's a tutorial show about I need to extend ServiceAdapter class in Java-side, which extends Invoke method. Do I need to extend other class instead of this to do what I want?

    Once the added button in grid is clicked, how to find which row and column the button is located in the grid event handler, like click event or some other events?

  • Sending mail issues. very confusing

    - by Dejan.S
    Hi my name is what, my name is who.. ops got carried away Now this might be a serverfault question and a stackoverflow question but I will go with it here because I don't really know the answer. I been sending mail a lot with asp.net before and never had problems like this before. I have setup a mail with this following code var list = new List<string> { "mail", "mail", "mail", "mail" }; var smtp = new SmtpClient("localhost", 25); var plainText = txtPlain.Text; var htmlText = Server.HtmlDecode(FCKeditor1.Value); foreach (var email in list) { var message = new MailMessage() { From = new MailAddress("my server mail"), ReplyTo = new MailAddress("mail") }; var mailMessage = Server.HtmlDecode(FCKeditor1.Value); message.To.Add(email); message.Subject = "Hi Enzorit"; message.Body = mailMessage; message.IsBodyHtml = true; message.BodyEncoding = System.Text.Encoding.GetEncoding("iso-8859-2"); var alternateViewHtml = AlternateView.CreateAlternateViewFromString(htmlText, null, MediaTypeNames.Text.Html); var alternateViewPlainText = AlternateView.CreateAlternateViewFromString(plainText, null, MediaTypeNames.Text.Plain); message.AlternateViews.Add(alternateViewHtml); message.AlternateViews.Add(alternateViewPlainText); smtp.Send(message); } now the issue becomes that some email clients get just plain while some get the html. Like on my hotmail on the computer i get the html but on my iphone i get the plain one. Why is that? and like that wasn't enough The mail wont deliver to some mails like any .pl email. Now here is where I am thinking that it might be a reverse DNS setup thing on my windows server 2008 issue + some company mails, it becomes spam, i had same issue with hotmail but that was solved when I added the plain. Anybody have had the problem before? I am very thankful for any answer I get.. thanks

  • Successful business model of small development tool

    - by Vladimir
    I have an idea on my mind to develop and sell small helpful developer tools like the tool asked in this question http://stackoverflow.com/questions/2562378/visual-objects-editor. I am looking for your answers which will shortly describe "How" and "What" to sell in order to be successful at that. I imagine different answers here from concrete to more general. Examples: "Sell your visual objects editor and I will buy it :-)" "Tbe only way to sell developer tool is to integrate it with known Java IDE" "Developers won't pay for the tools they use. Make it free and be famous" I encourage others to vote for the answers they like the most.
