• Ho do I extract a Outlook message nested into another using Apache POI - HSMF?

  - by Jan

  I am using Apache POI - HSMF to extract attachments from Outlooks msg-files. It works fine except for nested messages. If an msg is attached to another msg I am able to get the files. If a message is nested I get the information but I need the file. MAPIMessage msg = new MAPIMessage(fileName) for(AttachmentChunks attachment : msg.getAttachmentFiles()) { if(attachment.attachmentDirectory!=null){ MAPIMessage nestedMsg attachment.attachmentDirectory.getAsEmbededMessage(); // now save nestedMsg as a msg-file } } Is it possible to save the nested message file as a regular msg-file?

• MVC4 not binding a list of basic types

  - by admanb

  I cannot, for the life of me, get this data to bind. Here's my JavaScript: var params = { 'InvItemIDs': ["188475", "188490"]}; $.post("api/Orders/OrderFromInventory?" + $.param(params)) and the Controller action: public HttpResponseMessage OrderFromInventory(IList<int> InvItemIDs) { return new HttpResponseMessage(); } I've built the query string so that it's sending: ?InvItemIDs=188475&InvItemIDs=188490 as well as ?InvItemIDs[]=188475&InvItemIDs[]=188490 and even ?InvItemIDs[0]=188475&InvItemIDs[1]=188490 and none of them are binding. InvItemIDs is always null. What am I doing wrong? EDIT: So it turns out all this is a bug (or something) in the new Web API controller code in MVC4. As soon as I moved the exact same code over to a standard controller it started working. I'm still interested if anyone has any insight as to why the Web API would break this binding.

• Check constraint on table lookup

  - by bzamfir

  Hi, I have a table, department , with several bit fields to indicate department types One is Warehouse (when true, indicate the department is warehouse) And I have another table, ManagersForWarehouses with following structure: ID autoinc WarehouseID int (foreign key reference DepartmentID from departments) ManagerID int (foreign key reference EmployeeID from employees) StartDate EndDate To set new manager for warehouse, I insert in this table with EndDate null, and I have a trigger that sets EndDate for previous record for that warehouse = StartDate for new manager, so a single manager appears for a warehouse at a certain time. I want to add two check constraints as follows, but not sure how to do this do not allow to insert into ManagersForWarehouses if WarehouseID is not marked as warehouse Do not allow to uncheck Warehouse if there are records in ManagersForWarehouses Thanks

• jQuery mobile 1.1.0 slider: JS-object properties access?

  - by Koniak

  EDIT: This could be seen as a pure javascript objects question. The code can be found here: jquery.mobile-1.1.0.js I need to access properties of a jQuery mobile JS-object but is not sure how that is possible. In the jquery.mobile-1.1.0.js and mobile.slider is the following (see extend on line 5967): $.widget( "mobile.slider", $.mobile.widget, { ... _create: function() { ... $.extend( this, { slider: slider, handle: handle, valuebg: valuebg, dragging: false, beforeStart: null, userModified: false, mouseMoved: false }); Primarily the property I would like to read is the "dragging". I know i can execute the methods using: $("#slider").slider("refresh") Is there a similair way to access the properties? Thanks

• Set cookie value before view loaded in MVC?

  - by James123

  I need to set a cookie value before my view called. otherwise I have to refresh the page to get cookie value in the view. The problem here is the value of cookie will get in controller. [HttpGet] [Route("Abstract/{meetingCode}")] [AllowAnonymous] public ActionResult Index(string meetingCode) { var meetingAbstract = new MeetingAbstract(); meetingAbstract.Meeting = _abstractContext.GetMeetingWithMeetingCode(meetingCode); if (meetingAbstract.Meeting != null) { var cookie = new HttpCookie("_culture"); cookie.Value = meetingAbstract.Meeting.language.language_locale_code;//"en-US"; cookie.Expires = DateTime.Now.AddDays(365); cookie.Path = "/"; this.ControllerContext.HttpContext.Response.Cookies.Add(cookie); ... Any other way without refresh the page again to set cookie value?

• Rails passenger production cache definition

  - by mark

  Hi I'm having a bit of a problem with storing data in rails cache under production. What I currently have is this, though I have been trying to work this out for hours already: #production.rb config.cache_store = :mem_cache_store if defined?(PhusionPassenger) PhusionPassenger.on_event(:starting_worker_process) do |forked| if forked Rails.cache.instance_variable_get(:@data).reset end end end I am using a cron job to (try to) save remote data to the cache for display. It is logged as being written to the cache but reportedly null. If anyone could point me toward a decent current tutorial on the subject or offer guidance I'd be extremely grateful. This is really, really frustrating me. :(

• Can I catch bad pointer errors in C++?

  - by Simon

  Hi there, I was wondering if there is a possibility to catch errors like this in C++: object* p = new object; delete p; delete p; //this would cause an error, can I catch this? Can I check if the pointer is valid? Can I catch some exception? I know I could set the pointer p to NULL after the first object deletion. But just imagine you wouldn't do that. I am using VC++ with Visual Studio 2008/2010. Thank you

• How to access controls collection of dynamically loaded aspx page?

  - by Naasir

  Let's say I have two webforms, A.aspx and B.aspx, where B.aspx contains some simple web controls such as a textbox and a button. I'm trying to do the following: When A.aspx is requested, I want to dynamically call and load B.aspx into memory and output details of all the controls contained in B.aspx. Here is what I tried in the codebehind for A.aspx: var compiledType = BuildManager.GetCompiledType("~/b.aspx"); if (compiledType != null) { var pageB = (Page)Activator.CreateInstance(compiledType); } foreach (var control in pageB.Controls) { //output some details for each control, like it's name and type... } When I try the code above, the controls collection for pageB is always empty. Any ideas on how I can get this to work? Some other important details: both webforms utilize a master page (so the web controls in b.aspx are actually placed within a "content" tag) I've also tried using BuildManager.CreateInstanceFromVirtualPath. No luck.

• Operator as and generic classes

  - by abatishchev

  I'm writing .NET On-the-Fly compiler for CLR scripting and want execution method make generic acceptable: object Execute() { return type.InvokeMember(..); } T Execute<T>() { return Execute() as T; /* doesn't work: The type parameter 'T' cannot be used with the 'as' operator because it does not have a class type constraint nor a 'class' constraint */ // also neither typeof(T) not T.GetType(), so on are possible return (T) Execute(); // ok } But I think operator as will be very useful: if result type isn't T method will return null, instead of an exception! Is it possible to do?

• asp.net could a half submitted web page be processed?

  - by c00ke

  Having a weird bug in production and just wondering if it's possible for a half submitted web page to processed by the server? The page has no view state just using plain old html controls and accessing data displayed in repeater on the back end via Request.Form[name] etc. Is it possible for a request to be truncated perhaps due to lost internet connection and the page still processed by the server. Therefore if field not part of the request Request.Form[name] could result in null? I know can use fiddler to modify request but unfortunately we are not allowed to change group policy and change the proxy! Many Thanks

• How do I programmatically add a widget to a container created from GtkBuilder?

  - by Warner Young

  I've created a window that has some containers and widgets in it, and I want to add a new widget dynamically at run-time to one of the Vboxes in this window. So I have this code, which brings up the window: gtk_builder_add_from_file( g_builder, "window.xml", NULL ); mainwindow = GTK_WIDGET( gtk_builder_get_object( g_builder, "window" )); gtk_widget_show( mainwindow ); Then I create a new label, for example, and add it to one of the existing Vboxes, called "vbox_mid", like this: label = gtk_label_new( "Test label" ); vbox = GTK_WIDGET( gtk_builder_get_object( g_builder, "vbox_mid" )); gtk_box_pack_end( GTK_BOX( vbox ), label, TRUE, TRUE, 0 ); But this doesn't seem to work. I don't see a new label in the vbox. I have a feeling I'm missing something here, but I can't see what it is. I thought perhaps there was a special GtkBuilder call to add a widget dynamically, but I don't see anything that looks like that. I would really appreciate any help on this.

• A strange issue... No code changes getting reflected.

  - by sachin

  I am using netbeans to develop an applet, i have a piece of code which looked like this: ipAddresss = DEFAULT_IP; System.out.println("portlet.services.hostname:" + ipAddresss); Now I changed it to something like this: ipAddresss = DEFAULT_IP; System.out.println("portlet.services.hostname using default IP Address:" + ipAddresss); But no matter what I do, it sill keep on printing: portlet.services.hostname:null I have tried deleting all .netbeans folder from documents and settings, tried creating new project, but now i am completely baffled by this issue... So, the problem is, no matter what I do, no change is getting reflected when I run the program. Can there be a java applet cache, netbeans cache, i am not sure why...

• ASP.NET MVC Access model data in masterpage

  - by Paul

  I have created a UserSiteBaseController that gets commonly used data and sets the data to a UserSiteBaseViewData viewmodel in a method called SetViewData public T CreateViewData<T>() where T : UserSiteBaseViewData, new() { .... } I then create specific Controllers that inherit from the UserSiteBaseController as well as viewModels that inherit from UserSiteHomeViewData and can be created in the controller like so: public ActionResult Index(string slug) { Slug = slug; var viewData = CreateUserSiteHomeViewData<UserSiteHomeViewData>(); //If invalid slug - throw 404 not found if (viewData == null) return PageNotFound(); viewData.Announcements = _announcementsData.All(slug).ToList(); return View(viewData); } private T CreateUserSiteHomeViewData<T>() where T : UserSiteHomeViewData, new() { T viewData = CreateViewData<T>(); return viewData; } The UserBaseViewData holds data that needs to be use on every page so it would be great to be able to access this data from the Masterpage in a strongly typed manner. Is this possible or am I going about this in the incorrect manner?

• How compiling circular dependencies works?

  - by Fabio F.

  I've made the example in Java but I think (not tested) that it works in other (all?) languages. You have 2 files M.java that says public class MType{ XType x; MType(){ x = null;} } and another file XType.java (in the same directory) public class XType{ MType m; public XType(MType m){ this.m=m;} } Ok it's BAD programming , but.. if you run javac XType it compiles: compiles even MTypes because XType needs it. But.. MType needs XType.. how it works? How does the compiler know what is happening? Probably is a stupid question, but I would like to know how the compiler (javac or other compilers if you know.) manages that situation, not how to avoid it. I'm asking because i'm writing a precompiler and I would like to manage that situation.. Thank you

• Cannot running next process when a variable save no value

  First, I wanna compare between 2 tables tb_wrapper and tb_summary to get the data in the tb_wrapper that doesn't exist in the tb_summary then save in $link. If I don't get the same data, I want to print the result $link. When I don't get the not same data, I want it to go to another process. Here's the code : $q2 = mysql_query(" SELECT a.doc_url FROM tb_wrapper a LEFT JOIN tb_summary b ON a.doc_name = b.doc_summ WHERE b.doc_summ IS NULL"); while ($row = mysql_fetch_array($q2)){ $link = $row['doc_url']; if (!$link){ include 'next_process.php'; } else { print_r($link); } } it doesn't work. When I don't get the not same data or $link not save a value. table : CREATE TABLE tb1 (`id` int, `doc_name` varchar(100), `doc_url` varchar(50)) } CREATE TABLE tb2 (`id` int, `doc_summ` varchar(100)) }
