  • HTC Incredible displaying blank ImageView

    - by Todd
    HI, I have an app that displays an an image in an ImageView using the setImageDrawable(Drawable) method. However, with the release of the Droid Incredible the images are coming up as a blank screen. I am using Drawable.createFromPath(Environment.getExternalStorageDirectory() + "\imagefile") to access the image from the SD card. I don't get any sort of error, just a black screen. I will get a null pointer exception if after trying to load the image I try to access a property of the Drawable. This makes me believe that the Drawable wasn't loaded, but I don't know why or how to make it work. This code as been working on all other Android devices, so I'm not sure what is different with the Incredible. Unfortunately I don't have access to an Incredible to test on, so I've got to rely on others to test and send me the log files. Any help you can offer would be greatly appreciated. If anyone knows how to replicate this issue on the emulator, that would be helpful too. I've configured an emulator with firmware 7 and the correct screen resolution, but I was unable to replicate the issue. Thanks.

  • Find strong name signature without calling LoadAssembly

    - by Todd Kobus
    When reading a Windows PE file directly, I can't seem to find the strong name of a delay signed assembly. I can get to the CLR Header and read all the CLR header entries including the flags and the StrongNameSignature field. Unfortunately in a delay signed assembly the StrongNameSignature is zeroed out. Is the information in the MetaData directory specified within the CLR header? If so does anyone have an example of how to read this table? I am not interested in calling SN.exe or loading the assembly.

  • Testing methods called on yielded object

    - by Todd R
    I have the following controller test case: def test_showplain Cleaner.expect(:parse).with(@somecontent) Cleaner.any_instance.stubs(:plainversion).returns(@returnvalue) post :showplain, {:content => @somecontent} end This works fine, except that I want the "stubs(:plainversion)" to be an "expects(:plainversion)". Here's the controller code: def showplain Cleaner.parse(params[:content]) do | cleaner | @output = cleaner.plainversion end end And the Cleaner is simply: class Cleaner ### other code and methods ### def self.parse(@content) cleaner = Cleaner.new(@content) yield cleaner cleaner.close end def plainversion ### operate on @content and return ### end end Again, I can't figure out how to reliably test the "cleaner" that is made available from the "parse" method. Any suggestions?

  • Delete MSMQ Queue During Uninstall

    - by Todd Kobus
    Is it possible to delete a private message queue that was created by the service user? During uninstallation, we would like to clean up any message queues created by our application. For security purposes, access to these queues has been restricted to the current user (ServiceUser). During uninstall, we have admin privileges, but still get an access denied MessageQueueException when we attempt to delete the queue or modify the privs on the queue. Here is the cleanup code: public void DeleteAppQueues() { List<string> trash = new List<string>(); var machineQueues = MessageQueue.GetPrivateQueuesByMachine("."); foreach (var q in machineQueues) { if (IsAppQueue(q.QueueName)) { trash.Add(".\\" + q.QueueName); } q.Dispose(); } foreach (var queueName in trash) { try { using (MessageQueue delQueue = new MessageQueue(queueName)) { delQueue.SetPermissions("Everyone", MessageQueueAccessRights.FullControl, AccessControlEntryType.Allow); } MessageQueue.Delete(queueName); } catch (MessageQueueException ex) { // ex.Message is "Access to Message Queuing system is denied." } } }

  • Hide/Show problems on a questionerre application

    - by T. Todd
    I am doing an assignment involving the creation of a simple Quiz type form application. However, whenever I run the program, only the first answer shows for a multiple question and I cannot for the life of me figure out why. This is the contstructor: MultipleChoice dlg = new MultipleChoice( new Question("What is the capital of Zimbabwe?", new Answer("Paris", false), new Answer("Washington D.C.", false), new Answer("Harare", true), new Answer("Cairo", false), new Answer("N'Djamena", false))); if (dlg.ShowDialog() == DialogResult.OK) { if (dlg.Correct) MessageBox.Show("You got something right!"); else MessageBox.Show("You couldn't be more wrong"); } And this is the Question Form Code: private Question Q; public MultipleChoice (Question q) { Q = q; InitializeComponent(); textPrompt.Text = Q.Prompt; if (Q.A != null) { radioA.Text = Q.A.Prompt; } else radioA.Hide(); if (Q.B != null) { radioB.Text = Q.B.Prompt; } radioB.Hide(); if (Q.C != null) { radioC.Text = Q.C.Prompt; } radioC.Hide(); if (Q.D != null) { radioD.Text = Q.D.Prompt; } radioD.Hide(); if (Q.E != null) { radioE.Text = Q.E.Prompt; } radioE.Hide(); } public bool Correct { get { if (Q == null) return false; if (Q.A != null && Q.A.Correct && radioA.Checked) return true; if (Q.B != null && Q.B.Correct && radioB.Checked) return true; if (Q.C != null && Q.C.Correct && radioC.Checked) return true; if (Q.D != null && Q.D.Correct && radioD.Checked) return true; if (Q.E != null && Q.E.Correct && radioE.Checked) return true; return false; } Where have I gone wrong? Thank you, Travis

  • Determining whether a file is a duplicate

    - by Todd R
    Is there a reliable way to determine whether or not two files are the same? For example, two files with the same size and type may or may not be the same binarilly (yeah, I know it's not really a word). I assume that comparing one or two checksums of the files will help, but I wonder: How reliable are checksums at determining whether two files are different; what are the chances of two different files having the same checksum? Would reliability increase by applying additional checksum comparisons? Which checksum algorithm(s) would be the most efficient and/or reliable? Any ideas, suggestions or thoughts are appreciated! P.S. The code for this is being written in Java running on a nix system, but generic or platform agnostic input is most helpful.

  • Three most critical programming concepts

    - by Todd
    I know this has probably been asked in one form or fashion but I wanted to pose it once again within the context of my situation (and probably others here @ SO). I made a career change to Software Engineering some time ago without having an undergrad or grad degree in CS. I've supplemented my undergrad and grad studies in business with programming courses (VB, Java,C, C#) but never performed academic coursework in the other related disciplines (algorithms, design patterns, discrete math, etc.)...just mostly self-study. I know there are several of you who have either performed interviews and/or made hiring decisions. Given recent trends in demand, what would you say are the three most essential Comp Sci concepts that a developer should have a solid grasp of outside of language syntax? For example, I've seen blog posts of the "Absolute minimum X that every programmer must know" variety...that's what I'm looking for. Again if it's truly a redundancy please feel free to close; my feelings won't be hurt. (Closest ones I could find were http://stackoverflow.com/questions/164048/basic-programming-algorithmic-concepts- which was geared towards a true beginner, and http://stackoverflow.com/questions/648595/essential-areas-of-knowledge-which I didn't feel was concrete enough). Thanks in advance all! T.

  • Why represent shopping carts and order invoices differently in a domain model?

    - by Todd
    I've built some shopping cart systems in the past, but I always designed them such that the final order invoice is just a shopping cart that has been marked as "purchased". All the logic for adding/removing/changing items in a cart is also the logic for the order. All data is stored in the same tables in the database. But it seems this is not the proper way to design an e-commerce site.. Can someone explain the benefit of separating the shopping cart from invoices in the domain model? It seems to me this would lead to a lot of duplicated code, an extra set of tables in the database, and make it harder to maintain in the event the system need to start accommodating more complicated orders (like specifying selected options for an item which may or may not change the price/availability/shipping time of the order). I'm assuming I just haven't seen the light, as every book and other example I see seems to separate these two seemingly similar concerns -- but I can't find any explanation as to the benefit of doing such! It's also the case in the systems that I design that changes are often made after the initial order is confirmed. It's not uncommon for items to be removed, replaced, or added afterwards (but prior to fulfillment).

  • persist values/variables from page to page

    - by Todd
    Hello, I'm wondering if there's another solution to my problem, that's considered more the Sharepoint way. FIrstly, my site is an Internet site, not Intranet. The problem is, all I'm trying to do is save values/variables from page to page in Sharepoint. I know the issue with Session Variables, but this seems to be the only way I can see to accomplish this. I know there are webparts that can store this value, but am I wrong in thinking this won't be persisted from page to page? Basically, I'll be extending the Content Query Web Part to dynamically filter it's results based off of a variable/value. The user chooses their 'area' from a dropdown, and the CQWP in the site will change and query results based off of this value (It will be a provincial structure as it is a Canadian site, so if someone chooses the province 'Ontario', this value is saved in a global variable, and these extended CQWP that are throughout the site, will get this value, and query lists flagged as Ontario). Is Session variables the only solution? Thanks everyone!

  • Mac OS X: Best way to do runtime check for retina display?

    - by Todd Ditchendorf
    Given a Cocoa application which runs on Mac OS X 10.7 and later: What is the best way to check, at runtime, if your app is currently running on a Mac with at least one retina display attached? If checking for this sort of thing is just really wrong-headed, I fully welcome a well-reasoned explanation of why. But I'd still like to know :). It seems likely you could just do a check specifically for the new Mac Book Pro "Retina" hardware (the only Mac at this time which currently has a retina display), but ideally, I'd really prefer a more general/generic/future-proof way to check than this. Ideally, I'd like to know how to detect the retina display, not the specific Mac model which currently happens to ship with a retina display.

  • How can I return something other than an enum from an NServiceBus endpoint exposed as a WCF service?

    - by Todd Stout
    I have a service exposed as WCF via NServiceBus. Ultimately, I'd like to call to this service from silverlight. My WCF Service Interface looks like this: [ServiceContract] public interface ISettingsService { [OperationContract(Action = "http://tempuri.org/IWcfServiceOf_RequestSettingsMessage_SettingsResponseMessage/Process", ReplyAction = "http://tempuri.org/IWcfServiceOf_RequestSettingsMessage_SettingsResponseMessage/ProcessResponse") ] SettingsResponseMessage FetchSettings(RequestSettingsMessage request); } My NSB WCF service is defined as: public class CoreService : WcfService<RequestSettingsMessage, SettingsResponseMessage> { } When I invoke the FetchSettings method on the service, I get an exception: System.TypeInitializationException: The type initializer for 'NServiceBus.WcfSer vice`2' threw an exception. ---- System.InvalidOperationException: Centerlink.Services.Core.Msg.Settings.SettingsResponseMessage must be an enum representing error codes returned by the server. It seems that the WcfService< class is restricting the return type of a WCF method to be an enum. How can I have my service return something other than an enum? Do I need to create a custom implementation of NServiceBus.WcfService<?

  • perl - universal operator overload

    - by Todd Freed
    I have an idea for perl, and I'm trying to figure out the best way to implement it. The idea is to have new versions of every operator which consider the undefined value as the identity of that operation. For example: $a = undef + 5; # undef treated as 0, so $a = 5 $a = undef . "foo"; # undef treated as '', so $a = foo $a = undef && 1; # undef treated as false, $a = true and so forth. ideally, this would be in the language as a pragma, or something. use operators::awesome; However, I would be satisfied if I could implement this special logic myself, and then invoke it where needed: use My::Operators; The problem is that if I say "use overload" inside My::Operators only affects objects blessed into My::Operators. So the question is: is there a way (with "use overoad" or otherwise) to do a "universal operator overload" - which would be called for all operations, not just operations on blessed scalars. If not - who thinks this would be a great idea !? It would save me a TON of this kind of code if($object && $object{value} && $object{value} == 15) replace with if($object{value} == 15) ## the special "is-equal-to" operator

  • Are there any tools that can inline css?

    - by Todd R
    Because some email clients don't properly render external stylesheets (or even styles within the of an html email message), inlining css is a common approach to try to maintain consistent look and feel between a website and emails. But manually inlining styles is painful and error prone. I'm looking for a way to let users create messages using the same stylesheet as their website uses, but then converts the text to a more email appropriate format prior to sending. While it's certainly possible to write a tool that reads styles and the DOM, injecting the correct inline style for each element, I'm hoping there's already a tool available that does this. Unfortunately, my googling hasn't yielded any useful results. Do you know of any tools that can inline css styles? I'm not picky about the language, though if it's not open source, I'll probably just write my own.

  • Errors in UILabel

    - by Todd Davies
    I'm trying to use the FXlabel when following this (Adding a gradient label section) tutorial. This is some of the code inside my viewDidLoad method: self.logoLabel = [[FXLabel alloc] initWithFrame:CGRectMake(14, 11, 280, 87)]; [logoLabel setFont:[UIFont boldSystemFontOfSize:45]]; [logoLabel setTextColor:[UIColor whiteColor]]; [logoLabel setShadowColor:[UIColor blackColor]]; [logoLabel setShadowOffset:CGSizeMake(0, 2)]; [logoLabel setTextAlignment:UITextAlignmentCenter]; [logoLabel setBackgroundColor:[UIColor clearColor]]; [logoLabel setText:@"Attorney Biz"]; [logoLabel setGradientStartColor:[UIColor colorWithRed:163.0/255 green:203.0/255 blue:222.0/255 alpha:1.0]]; [logoLabel setGradientEndColor:[UIColor whiteColor]]; Unfortnuately, I get an error "No visible @interface for 'UILabel' declares the selector 'setGradientStartColor'" at the second-to-last line and "No visible @interface for 'UILabel' declares the selector 'setGradientEndColor'" Can somebody explain how to remove these errors?

  • Subquery with multiple results combined into a single field?

    - by Todd
    Assume I have these tables, from which i need to display search results in a browser: Table: Containers id | name 1 Big Box 2 Grocery Bag 3 Envelope 4 Zip Lock Table: Sale id | date | containerid 1 20100101 1 2 20100102 2 3 20091201 3 4 20091115 4 Table: Items id | name | saleid 1 Barbie Doll 1 2 Coin 3 3 Pop-Top 4 4 Barbie Doll 2 5 Coin 4 I need output that looks like this: itemid itemname saleids saledates containerids containertypes 1 Barbie Doll 1,2 20100101,20100102 1,2 Big Box, Grocery Bag 2 Coin 3,4 20091201,20091115 3,4 Envelope, Zip Lock 3 Pop-Top 4 20091115 4 Zip Lock The important part is that each item type only gets one record/row in the return on the screen. I accomplished this in the past by returning multiple rows of the same item and using a scripting language to limit the output. However, this makes the ui overly complicated and loopy. So, I'm hoping I can get the database to spit out only as many records as there are rows to display. This example may be a bit extreme because of the 2 joins needed to get to the container from the item (through the sale table). I'd be happy for just an example query that outputs this: itemid itemname saleids saledates 1 Barbie Doll 1,2 20100101,20100102 2 Coin 3,4 20091201,20091115 3 Pop-Top 4 20091115 I can only return a single result in a subquery, so I'm not sure how to do this.

  • Complicated Order By Clause?

    - by Todd
    Hi. I need to do what to me is an advanced sort. I have this two tables: Table: Fruit fruitid | received | basketid 1 20100310 2 2 20091205 3 3 20100220 1 4 20091129 2 Table: Basket id | name 1 Big Discounts 2 Premium Fruit 3 Standard Produce I'm not even sure I can plainly state how I want to sort (which is probably a big part of the reason I can't seem to write code to do it, lol). I do a join query and need to sort so everything is organized by basketid. The basketid that has the oldest fruit.received date comes first, then the other rows with the same basketid by date asc, then the basketid with the next earliest fruit.received date followed by the other rows with the same basketid, and so on. So the output would look like this: Fruitid | Received | Basket 4 20091129 Premuim Fruit 1 20100310 Premuim Fruit 2 20091205 Standard Produce 3 20100220 Big Discounts Any ideas how to accomplish this in a single execution?

  • How to have NHibernate persist a String.Empty property value as NULL

    - by Todd
    I have a fairly simple class that I want to save to SQL Server via NHibernate (w/ Fluent mappings). The class is made up mostly of optional string fields. My problem is I default the class fields to string.empty to avoid NullRefExceptions and when NHibernate saves the row to the database each column contains an empty string instead of null. Question: Is there a way for me to get NHibernate to automatically save null when the string property is an empty string? Or do I need to litter my code with if (string.empty) checks?

  • Offline Database Write Cache in C#

    - by Todd Gardner
    I have a windows service that receives a large amount of data that needs to be transformed and persisted to a database. To ensure that we do not lose data, I want to create a "Write cache" for the data that will continue regardless if the database is online. Once the database becomes available again, I would want it to flush the content of the cache back into the database. I've seen some articles indicating that I might be able to do this with NHibernate, but I haven't found it conclusively. What options exist for this, and is NHibernate the appropriate direction?

  • How do I change the number of thumbnails seen in the Android sample Home application?

    - by Todd
    I am working with the sample Home application project on http://developer.android.com/resources/samples/Home/index.html I've added another value to the THUMBS_IDS and IMAGE_IDS Integer arrays in the Wallpaper class for a total of four wallpaper options. When I run the application with Device API version 7, Skin: HVGA, hw.lcd.density: 160, in portrait layout, the fourth wallpaper option is not shown. I need to use the directional keys in the emulator to see the 4th wallpaper option, because the first option is centered. I have modified only the wallpaper.xml file with a variety of android:layout_* options with no success at this point. How do I show all four of my wallpaper options?

  • How do I add a property to a Javascript Object using a variable as the name?

    - by Todd R
    I'm pulling items out of the DOM with JQuery and want to set a property on an object using the id of the DOM element. For example: obj = {}; jQuery(itemsFromDom).each(function() { element = jQuery(this); name = element.attr("id"); value = element.attr("value"); //Here's the problem obj.name = value; }); If "itemsFromDom" includes an element with an id of "myId", I want "obj" to have a property named "myId". The above gives me "name". How, in javascript, do I name a property of an object using a variable?

  • Is there an alias for 'this' in TypeScript?

    - by Todd
    I've attempted to write a class in TypeScript that has a method defined which acts as an event handler callback to a jQuery event. class Editor { textarea: JQuery; constructor(public id: string) { this.textarea = $(id); this.textarea.focusin(onFocusIn); } onFocusIn(e: JQueryEventObject) { var height = this.textarea.css('height'); // <-- This is not good. } } Within the onFocusIn event handler, TypeScript sees 'this' as being the 'this' of the class. However, jQuery overrides the this reference and sets it to the DOM object associated with the event. One alternative is to define a lambda within the constructor as the event handler, in which case TypeScript creates a sort of closure with a hidden _this alias. class Editor { textarea: JQuery; constructor(public id: string) { this.textarea = $(id); this.textarea.focusin((e) => { var height = this.textarea.css('height'); // <-- This is good. }); } } My question is, is there another way to access the this reference within the method-based event handler using TypeScript, to overcome this jQuery behavior?

  • Problem using Min(field)

    - by Todd
    have these two queries: SELECT classroomid AS crid, startdate AS msd FROM unitTemplates where classroomid = 6 GROUP BY classroomid and: SELECT classroomid AS crid, Min(startdate) AS msd FROM unitTemplates where classroomid = 6 GROUP BY classroomid The second query uses the minimum function. There is only one record in my table with a classroomid of 6. The first query returns msd = 20100505, the second query returns msd = 0 (instead of the expected 20100505). If I change the "Min" to "Max" it returns the highest (and only) startdate (20100505). Why doesn't MySQL like the Min function I'm using?
