  • What is a good way to assign order #s to ordered rows in a table in Sybase

    - by DVK
    I have a table T (structure below) which initially contains all-NULL values in an integer order column: col1 varchar(30), col2 varchar(30), order int NULL I also have a way to order the "colN" columns, e.g. SELECT * FROM T ORDER BY some_expression_involving_col1_and_col2 What's the best way to assign - IN SQL - numeric order values 1-N to the order table, so that the order values match the order of rows returned by the above ORDER BY? In other words, I would like a single query (Sybase SQL syntax so no Oracle's rowcount) which assigns order values so that SELECT * FROM T ORDER BY order returns 100% same order of rows as the query above. The query does NOT necessarily need to update the table T in place, I'm OK with creating a copy of the table T2 if that'll make the query simpler. NOTE1: A solution must be real query or a set of queries, not involving a loop or a cursor. NOTE2: Assume that the data is uniquely orderable according to the order by above - no need to worry about situation when 2 rows can be assigned the same order at random. NOTE3: I would prefer a generic solution, but if you wish a specific example of ordering expression, let's say: SELECT * FROM T ORDER BY CASE WHEN col1="" THEN "AAAAAA" ELSE col1 END, ISNULL(col2, "ZZZ")

  • Testing for interface implementation in WCF/SOA

    - by rabidpebble
    I have a reporting service that implements a number of reports. Each report requires certain parameters. Groups of logically related parameters are placed in an interface, which the report then implements: [ServiceContract] [ServiceKnownType(typeof(ExampleReport))] public interface IService1 { [OperationContract] void Process(IReport report); } public interface IReport { string PrintedBy { get; set; } } public interface IApplicableDateRangeParameter { DateTime StartDate { get; set; } DateTime EndDate { get; set; } } [DataContract] public abstract class Report : IReport { [DataMember] public string PrintedBy { get; set; } } [DataContract] public class ExampleReport : Report, IApplicableDateRangeParameter { [DataMember] public DateTime StartDate { get; set; } [DataMember] public DateTime EndDate { get; set; } } The problem is that the WCF DataContractSerializer does not expose these interfaces in my client library, thus I can't write the generic report generating front-end that I plan to. Can WCF expose these interfaces, or is this a limitation of the serializer? If the latter case, then what is the canonical approach to this OO pattern? I've looked into NetDataContractSerializer but it doesn't seem to be an officially supported implementation (which means it's not an option in my project). Currently I've resigned myself to including the interfaces in a library that is common between the service and the client application, but this seems like an unnecessary extra dependency to me. Surely there is a more straightforward way to do this? I was under the impression that WCF was supposed to replace .NET remoting; checking if an object implements an interface seems to be one of the most basic features required of a remoting interface?

  • Is there a workaround for Linux mono's refusal to acknowledge that I have resized the columns of my

    - by fantius
    When I resize a column, it does not redraw the data with the updated alignment. I've tried Invalidating, Refreshing, and a few other things. Nothing has worked. Does anyone know a workaround? I have not tried this in mono for Windows. To see what I mean, drop this control on a form, and run it in mono for Linux: using System; using System.Collections.Generic; using System.Text; using System.Windows.Forms; using System.Drawing; class MyListView : ListView { private readonly List<ListViewItem> items_ = new List<ListViewItem>(); public MyListView() { VirtualMode = true; Columns.Add("Col 1"); Columns.Add("Col 2"); Columns.Add("Col 3"); Add(new ListViewItem(new[] { "a", "b", "c" })); Add(new ListViewItem(new[] { "a", "b", "c" })); Add(new ListViewItem(new[] { "a", "b", "c" })); Add(new ListViewItem(new[] { "a", "b", "c" })); Add(new ListViewItem(new[] { "a", "b", "c" })); } protected override void OnRetrieveVirtualItem(RetrieveVirtualItemEventArgs e) { e.Item = items_[e.ItemIndex]; base.OnRetrieveVirtualItem(e); } public void Add(ListViewItem item) { items_.Add(item); VirtualListSize = items_.Count; } protected override void OnDrawColumnHeader(DrawListViewColumnHeaderEventArgs e) { e.DrawText(); base.OnDrawColumnHeader(e); } protected override void OnDrawSubItem(DrawListViewSubItemEventArgs e) { var text = ((ListViewItem.ListViewSubItem)e.SubItem).Text; using (var brush = new SolidBrush(e.SubItem.ForeColor)) { e.Graphics.DrawString(text, Font, brush, e.Bounds); } base.OnDrawSubItem(e); } protected override void OnColumnWidthChanged(ColumnWidthChangedEventArgs e) { base.OnColumnWidthChanged(e); Invalidate(true); // Nope, that didn't work Refresh(); // Nope, that didn't work } }

  • Tablet interface for the physically disabled?

    - by Glenn
    My sister has Cerebral Palsy, which in her case means she has only gross motor control and her speech is slurred. Implications should be obvious: traditional computer/phone/tablet interfaces won't work for her and she can't speak clearly enough for speech recognition software to help her at all. She enjoys reading but has difficulty holding the book and/or turning a page. There are a few options for helping her use a computer, but nothing for tablets or eReaders. That's where you come in. I would like to make (or buy, if such a thing exists) a better interface to an Android tablet that would work for someone with little to no physical dexterity or speech ability. I'd also be interested in work on the Kindle or iPad, but I'm most familiar with Android so I'm starting there. I know Android has Bluetooth capability. Is it possible to interface a joystick to control the Android device? By "control", I mean the entire operating system - selecting an app, launching it, controlling the menus, etc. I want to give her control over the whole thing, not just a specific app. On a PC this can be accomplished by creating a generic USB HID interface and an arcade joystick to move the mouse over the screen and click on thigns. Is it possible to do something like that in Android? Any help you can offer would be greatly appreciated. Thanks!

  • MS CRM 4.0 Remove inactive account from another list

    - by Ekaterina
    Hi, I have the following problem, on which I can't seem to find an answer... I have a CRM 4.0 system and I want to achieve the following: When I have a contact/account that's inactive to remove it from another list, for example the Marketing list. So I already have everything, up to the removing part. I have a collection with the inactive accounts/contacts (The ID's(GUID)), I just need to remove somehow the member from the list. So there is a class RemoveMemberListRequest which looks like the correct one, the only problem is, somehow I can't get it to work. foreach (Guid currentMember in inactiveMembers) { RemoveMemberListRequest req = new RemoveMemberListRequest(); req.ListId = context.PrimaryEntityId; req.EntityId = currentMember ; RemoveMemberListResponse rmlResp = (RemoveMemberListResponse)crmService.Execute(req); } When It tries to Execute, the request it fails, with very generic error, that it was unable to execute the request. I am also not sure if that's the correct way of doing it... There is another class that seems to have a property that might be useful: QualifyMemberListRequest With property: OverrideorRemove But I don't really understand how this one works, and I couldn't find enough information. Anybody?

  • JSP: How can I still get the code on my error page to run, even if I can't display it?

    - by Josh Hinman
    I've defined an error-page in my web.xml: <error-page> <exception-type>java.lang.Exception</exception-type> <location>/error.jsp</location> </error-page> In that error page, I have a custom tag that I created. The tag handler for this tag e-mails me the stacktrace of whatever error occurred. For the most part this works great. Where it doesn't work great is if the output has already begun being sent to the client at the time the error occurs. In that case, we get this: SEVERE: Exception Processing ErrorPage[exceptionType=java.lang.Exception, location=/error.jsp] java.lang.IllegalStateException I believe this error happens because we can't redirect a request to the error page after output has already started. The work-around I've used is to increase the buffer size on particularly large JSP pages. But I'm trying to write a generic error handler that I can apply to existing applications, and I'm not sure it's feasible to go through hundreds of JSP pages making sure their buffers are big enough. Is there a way to still allow my stack trace e-mail code to execute in this case, even if I can't actually display the error page to the client?

  • what makes a Tomcat5.5 cannot be "aware" of new Java Web Applications?

    - by Michael Mao
    This is for uni homework, but I reckon it is more a generic problem to the Tomcat Server(version 5.5.27) on my uni. The problem is, I first did a skeleton Java Web Application (Just a simple Servlet and a welcome-file, nothing complicated, no lib included) using NetBeans 6.8 with the bundled Tomcat 6.0.20 (localhost:8084/WSD) Then, to test and prove it is "portable" and "auto-deploy-able", I cleaned and built a WSD.war file and dropped it onto my Xampp Tomcat (localhost:8080/WSD). The war extracted everything accordingly and I can see identical output from this Tomcat. So far, so good. However, after I tried to drop to war onto uni server, funny thing happens: uni server Even though I've changed the war permission to 755, it is simply not "responding". I then copied the extracted files to uni server, the MainServlet cannot be recognized from within its Context Path "/WSD", basically nothing works, expect the static index.jsp. I tried several times to stop and restart uni Tomcat, it doesn't help? I wonder what makes this happen? Is there anything I did wrong with my approach? To be frank I paid no attention to a server not under my control, and I am unfortunately not a real active day-to-day Java Programmer now. I understand the fundamentals of MVC, Servelets, JSPs, JavaBeans, but I really feel frustrated by this, as I cannot see why... Or, should I ask, a Java Web Application, after cleaned and built by NetBeans6.8, is self-contained and self-configured so ready to be deployed to any Java Web Container? I know, I can certainly program everything in plain old JSP, but this is soooo... unacceptable to myself... Update : I am now wondering if there is any free Tomcat Hosting so that I would like to see if my war file and/or my web app can go with them without any configuration at all?

  • Joining Tables Based on Foreign Keys

    - by maestrojed
    I have a table that has a lot of fields that are foreign keys referencing a related table. I am writing a script in PHP that will do the db queries. When I query this table for its data I need to know the values associated with these keys not the key. How do most people go about this? A 101 way to do this would be to query this table for its data including the foreign keys and then query the related tables to get each key's value. This could be a lot of queries (~10). Question 1: I think I could write 1 query with a bunch of joins. Would that be better? This approach also requires the querying script to know which table fields are foreign keys. Since I have many tables like this but all with different fields, this means writing nice generic functions is hard. MySQL InnoDB tables allow for foreign constraints. I know the database has these set up correctly. Question 2: What about the idea of querying the table and identifying what the constraints are and then matching them up using whatever process I decide on from Question 1. I like this idea but never see it being used in code. Makes me think its not a good idea for some reason. I would use something like SHOW CREATE TABLE tbl_name; to find what constraints/relationships exist for that table. Thank you for any suggestions or advice.

  • Django: Applying Calculations To A Query Set

    - by TheLizardKing
    I have a QuerySet that I wish to pass to a generic view for pagination: links = Link.objects.annotate(votes=Count('vote')).order_by('-created')[:300] This is my "hot" page which lists my 300 latest submissions (10 pages of 30 links each). I want to now sort this QuerySet by an algorithm that HackerNews uses: (p - 1) / (t + 2)^1.5 p = votes minus submitter's initial vote t = age of submission in hours Now because applying this algorithm over the entire database would be pretty costly I am content with just the last 300 submissions. My site is unlikely to be the next digg/reddit so while scalability is a plus it is required. My question is now how do I iterate over my QuerySet and sort it by the above algorithm? For more information, here are my applicable models: class Link(models.Model): category = models.ForeignKey(Category, blank=False, default=1) user = models.ForeignKey(User) created = models.DateTimeField(auto_now_add=True) modified = models.DateTimeField(auto_now=True) url = models.URLField(max_length=1024, unique=True, verify_exists=True) name = models.CharField(max_length=512) def __unicode__(self): return u'%s (%s)' % (self.name, self.url) class Vote(models.Model): link = models.ForeignKey(Link) user = models.ForeignKey(User) created = models.DateTimeField(auto_now_add=True) def __unicode__(self): return u'%s vote for %s' % (self.user, self.link) Notes: I don't have "downvotes" so just the presence of a Vote row is an indicator of a vote or a particular link by a particular user.

  • Getting the data inside the C# web service from Jsonified string

    - by gnomixa
    In my JS I use Jquery's $ajax functions to call the web service and send the jsonified data to it. The data is in the following format: var countries = { "1A": { id: "1A", name: "Andorra" }, "2B": { id: 2B name: "Belgium" }, ..etc }; var jsonData = JSON.stringify({ data: data }); //then $ajax is called and it makes the call to the c# web service On the c# side the web service needs to unpack this data, currently it comes in as string[][] data type. How do I convert it to the format so I can refer to the properties such as .id and .name? Assuming I have a class called Sample with these properties? Thanks! EDIT: Here is my JS code: var jsonData = JSON.stringify(countries); $.ajax({ type: 'POST', url: 'http://localhost/MyService.asmx/Foo', contentType: 'application/json; charset=utf-8', data: jsonData, success: function (msg) { alert(msg.d); }, error: function (xhr, status) { switch (status) { case 404: alert('File not found'); break; case 500: alert('Server error'); break; case 0: alert('Request aborted'); break; default: alert('Unknown error ' + status); } } }); inside c# web service I have: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Services; using System.Data; using System.Collections; using System.IO; using System.Web.Script.Services; [WebMethod] [ScriptMethod] public string Foo(IDictionary<string, Country> countries) { return "success"; }

  • How do I find and open a file in a Visual Studio 2005 add-in?

    - by Charles Randall
    I'm making an add-in with Visual Studio 2005 C# to help easily toggle between source and header files, as well as script files that all follow a similar naming structure. However, the directory structure has all of the files in different places, even though they are all in the same project. I've got almost all the pieces in place, but I can't figure out how to find and open a file in the solution based only on the file name alone. So I know I'm coming from, say, c:\code\project\subproject\src\blah.cpp, and I want to open c:\code\project\subproject\inc\blah.h, but I don't necessarily know where blah.h is. I could hardcode different directory paths but then the utility isn't generic enough to be robust. The solution has multiple projects, which seems to be a bit of a pain as well. I'm thinking at this point that I'll have to iterate through every project, and iterate through every project item, to see if the particular file is there, and then get a proper reference to it. But it seems to me there must be an easier way of doing this.

  • Populate asp.net MVC Index page with data from the database

  • MVC2 DataAnnotations on ViewModel - Don't understand using it with MVVM pattern

    - by ScottSEA
    I have an MVC2 Application that uses MVVM pattern. I am trying use Data Annotations to validate form input. In my ThingsController I have two methods: [HttpGet] public ActionResult Index() { return View(); } public ActionResult Details(ThingsViewModel tvm) { if (!ModelState.IsValid) return View(tvm); try { Query q = new Query(tvm.Query); ThingRepository repository = new ThingRepository(q); tvm.Things = repository.All(); return View(tvm); } catch (Exception) { return View(); } } My Details.aspx view is strongly typed to the ThingsViewModel: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Config.Web.Models.ThingsViewModel>" %> The ViewModel is a class consisting of a IList of returned Thing objects and the Query string (which is submitted on the form) and has the Required data annotation: public class ThingsViewModel { public IList<Thing> Things{ get; set; } [Required(ErrorMessage="You must enter a query")] public string Query { get; set; } } When I run this, and click the submit button on the form without entering a value I get a YSOD with the following error: The model item passed into the dictionary is of type 'Config.Web.Models.ThingsViewModel', but this dictionary requires a model item of type System.Collections.Generic.IEnumerable`1[Config.Domain.Entities.Thing]'. How can I get Data Annotations to work with a ViewModel? I cannot see what I'm missing or where I'm going wrong - the VM was working just fine before I started mucking around with validation.

  • Custom control doesn't fire validation

    - by Ed Woodcock
    I've written a custom ASP.net control that descends from LinkButton and overrides the Render() method. I'm using it to replace ImageButtons in the site I'm working on so we don't have to have an image for each button. This control works fine, does the required post-backs etc., however it doesn't fire the validators in its validation group. This is obviously an issue. The code for the control is (condensed) as follows: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public class CustomButton : LinkButton { public string SpanCssClass { get; set; } protected override void Render(HtmlTextWriter writer) { if (!Visible) { return; } writer.AddAttribute(HtmlTextWriterAttribute.Name, UniqueID); writer.AddAttribute(HtmlTextWriterAttribute.Id, ClientID); writer.AddAttribute(HtmlTextWriterAttribute.Class, CssClass); string postback = string.IsNullOrEmpty(OnClientClick) ? "javascript:__doPostBack('" + UniqueID + "','');" : OnClientClick; writer.AddAttribute(HtmlTextWriterAttribute.Href, postback); writer.RenderBeginTag(HtmlTextWriterTag.A); writer.AddAttribute(HtmlTextWriterAttribute.Class, SpanCssClass); writer.RenderBeginTag(HtmlTextWriterTag.Span); writer.Write(Text); writer.RenderEndTag(); writer.RenderEndTag(); } } Does anyone know why this would not be causing the validators to fire? I was under the impression that leaving all the other methods in LinkButton un-overridden would leave all the other functionality the same!

  • DataSets to POCOs - an inquiry regarding DAL architecture

    - by alexsome
    Hello all, I have to develop a fairly large ASP.NET MVC project very quickly and I would like to get some opinions on my DAL design to make sure nothing will come back to bite me since the BL is likely to get pretty complex. A bit of background: I am working with an Oracle backend so the built-in LINQ to SQL is out; I also need to use production-level libraries so the Oracle EF provider project is out; finally, I am unable to use any GPL or LGPL code (Apache, MS-PL, BSD are okay) so NHibernate/Castle Project are out. I would prefer - if at all possible - to avoid dishing out money but I am more concerned about implementing the right solution. To summarize, there are my requirements: Oracle backend Rapid development (L)GPL-free Free I'm reasonably happy with DataSets but I would benefit from using POCOs as an intermediary between DataSets and views. Who knows, maybe at some point another DAL solution will show up and I will get the time to switch it out (yeah, right). So, while I could use LINQ to convert my DataSets to IQueryable, I would like to have a generic solution so I don't have to write a custom query for each class. I'm tinkering with reflection right now, but in the meantime I have two questions: Are there any problems I overlooked with this solution? Are there any other approaches you would recommend to convert DataSets to POCOs? Thanks in advance.

  • Database Table Schema and Aggregate Roots

    - by bretddog
    Hi, Applicaiton is single user, 1-tier(1 pc), database SqlCE. DataService layer will be (I think) : Repository returning domain objects and quering database with LinqToSql (dbml). There are obviously a lot more columns, this is simplified view. http://img573.imageshack.us/img573/3612/ss20110115171817w.png This is my first attempt of creating a 2 tables database. I think the table schema makes sense, but I need some reassurance or critics. Because the table relations looks quite scary to be honest. I'm hoping you could; Look at the table schema and respond if there are clear signs of troubles or errors that you spot right away.. And if you have time, Look at Program Summary/Questions, and see if the table layout makes makes sense to those points. Please be brutal, I will try to defend :) Program summary: a) A set of categories, each having a set of strategies (1:m) b) Each day a number of items will be produced. And each strategy MAY reference it. (So there can be 50 items, and a strategy may reference 23 of them) c) An item can be referenced by more than one strategy. So I think it's an m:m relation. d) Status values will be logged at fixed time-fractions through the day, for: - .... each Strategy.....each StrategyItem....each item e) An action on an item may be executed by a strategy that reference it. - This is logged as ItemAction (Could have called it StrategyItemAction) User Requsts b) - e) described the main activity mode of the program. To work with only today's DayLog , for each category. 2nd priority activity is retrieval of history, which typically will be From all categories, from day x to day y; Get all StrategyDailyLog. Questions First, does the overall layout look sound? I'm worried to see that there are so many relationships in all directions, connecting everything. Is this normal, or does it look like trouble? StrategyItem is made to represent an m:m relationship. Is it correct as I noted 1:m / 1:1 (marked red) ? StrategyItemTimeLog and ItemTimeLog; Logs values that both need to be retrieved together, when retreiving a StrategyItem. Reason I separated is that the first one is strategy-specific, and several strategies can reference same item. So I thought not to duplicate those values that are not dependent no strategy, but only on the item. Hence I also dragged out the LogTime, as it seems to be the only parameter to unite the logs. But this all looks quite disturbing with those 3 tables. Does it make sense at all? Or you have suggestion? Pink circles shows my vague attempt of Aggregate Root Paths. I've been thinking in terms of "what entity is responsible for delete". Though I'm unsure about the actual root. I think it's Category. Does it make sense related to User Requests described above?

  • How can I track the last location of a shipment effeciently using latest date of reporting?

    - by hash
    I need to find the latest location of each cargo item in a consignment. We mostly do this by looking at the route selected for a consignment and then finding the latest (max) time entered against nodes of this route. For example if a route has 5 nodes and we have entered timings against first 3 nodes, then the latest timing (max time) will tell us its location among the 3 nodes. I am really stuck on this query regarding performance issues. Even on few hundred rows, it takes more than 2 minutes. Please suggest how can I improve this query or any alternative approach I should acquire? Note: ATA= Actual Time of Arrival and ATD = Actual Time of Departure SELECT DISTINCT(c.id) as cid,c.ref as cons_ref , c.Name, c.CustRef FROM consignments c INNER JOIN routes r ON c.Route = r.ID INNER JOIN routes_nodes rn ON rn.Route = r.ID INNER JOIN cargo_timing ct ON c.ID=ct.ConsignmentID INNER JOIN (SELECT t.ConsignmentID, Max(t.firstata) as MaxDate FROM cargo_timing t GROUP BY t.ConsignmentID ) as TMax ON TMax.MaxDate=ct.firstata AND TMax.ConsignmentID=c.ID INNER JOIN nodes an ON ct.routenodeid = an.ID INNER JOIN contract cor ON cor.ID = c.Contract WHERE c.Type = 'Road' AND ( c.ATD = 0 AND c.ATA != 0 ) AND (cor.contract_reference in ('Generic','BP001','020-543-912')) ORDER BY c.ref ASC

  • Using generics in F# to create an EnumArray type

    - by Matthew
    I've created an F# class to represent an array that allocates one element for each value of a specific enum. I'm using an explicit constructor that creates a dictionary from enum values to array indices, and an Item property so that you can write expressions like: let my_array = new EnumArray<EnumType, int> my_array.[EnumType.enum_value] <- 5 However, I'm getting the following obscure compilation error at the line marked with '// FS0670' below. error FS0670: This code is not sufficiently generic. The type variable ^e when ^e : enum<int> and ^e : equality and ^e : (static member op_Explicit : ^e -> int) could not be generalized because it would escape its scope. I'm at a loss - can anyone explain this error? type EnumArray< 'e, 'v when 'e : enum<int> and 'e : equality and ^e : (static member op_Explicit : ^e -> int) > = val enum_to_int : Dictionary<'e, int> val a : 'v array new() as this = { enum_to_int = new Dictionary<'e, int>() a = Array.zeroCreate (Enum.GetValues(typeof<'e>).Length) } then for (e : obj) in Enum.GetValues(typeof<'e>) do this.enum_to_int.Add(e :?> 'e, int(e :?> 'e)) member this.Item with get (idx : 'e) : 'v = this.a.[this.enum_to_int.[idx]] // FS0670 and set (idx : 'e) (c : 'v) = this.a.[this.enum_to_int.[idx]] <- c

  • Binding a ListBox's SelectedItem in the presence of BindingNavigator

    - by Reinderien
    Hello. I'm trying to bind a ListBox's SelectedItem data to a property. The following code is an example: using System; using System.Collections.Generic; using System.Windows.Forms; namespace BindingFailure { static class Program { class OuterObject { public string selected { get; set; } public List<string> strings { get; set; } } public static void Main() { List<OuterObject> objs = new List<OuterObject>() { new OuterObject(), new OuterObject() }; objs[0].strings = new List<string> { "one", "two", "three" }; objs[1].strings = new List<string> { "four", "five", "six" }; Form form = new Form(); BindingSource obs = new BindingSource(objs, null), ibs = new BindingSource(obs, "strings"); BindingNavigator nav = new BindingNavigator(obs); ListBox lbox = new ListBox(); lbox.DataSource = ibs; lbox.DataBindings.Add(new Binding("SelectedItem", obs, "selected")); form.Controls.Add(nav); form.Controls.Add(lbox); lbox.Location = new System.Drawing.Point(30, 30); Application.Run(form); } } } If you just select an item, move forward, select an item and then exit, it works as expected. But if you switch back and forth between the two outer objects with the navigator, the selected item seems to be overwritten with an incorrect value. Ideas on how to fix this? Thanks in advance.

  • Debugging an XBAP application with 64-bit browser

    - by Anne Schuessler
    We have an XBAP application that fails when opened in Internet Explorer 8 64 bit. We only get a pretty generic error which makes it hard to determine where the error is coming from. I'm trying to find a way to debug the application with IE 8 64 bit, but I haven't figured out how to do this. I can't set the 64 bit version as the standard browser and overwriting the browser path in the browsers.xml for Visual Studio doesn't work as well. It just gets overwritten as soon as I hit F5 to debug to point to the 32 bit IE. I have figured out how to start the application from Debug with the 64 bit browser by changing the Debug options from "Start browser with URL" to "Start external program" and setting the command line arguments to point to the bin folder. Unfortunately then the XBAP is looking for its config.deploy file which doesn't seem to be generated during regular debug. This doesn't happen when using "Start browser with URL" and the application doesn't seem to care for this file then. Does anybody know why there's a difference between "Start browser with URL" and "Start external program" in the Debug options which might cause this difference in behavior when Debug is started? Also, does anybody know how to successfully debug an XBAP with a 64-bit browser?

  • Referencing not-yet-defined variables - Java

    - by user2537337
    Because I'm tired of solving math problems, I decided to try something more engaging with my very rusty (and even without the rust, very basic) Java skills. I landed on a super-simple people simulator, and thus far have been having a grand time working through the various steps of getting it to function. Currently, it generates an array of people-class objects and runs a for loop to cycle through a set of actions that alter the relationships between them, which I have stored in a 2d integer array. When it ends, I go look at how much they all hate each other. Fun stuff. Trouble has arisen, however, because I would like the program to clearly print what action is happening when it happens. I thought the best way to do this would be to add a string, description, to my "action" class (which stores variables for the actor, reactor, and the amount the relationship changes). This works to a degree, in that I can print a generic message ("A fight has occurred!") with no problem. However, ideally I would like it to be a little more specific ("Person A has thrown a rock at Person B's head!"). This latter goal is proving more difficult: attempting to construct an action with a description string that references actor and reactor gets me a big old error, "Cannot reference field before it is defined." Which makes perfect sense. I believe I'm not quite in programmer mode, because the only other way I can think to do this is an unwieldy switch statement that negates the need for each action to have its own nicely-packaged description. And there must be a neater way. I am not looking for examples of code, only a push in the direction of the right concept to handle this.
