  • Will a mulitouch touch screen equipped PC allow me to simulate real Android UI's without an Android device ?

    - by Scott Davies
    Hi, I have recently purchased a Samsung Galaxy Tab as an Android 2.x testbed (I am aware that 2.3 might not run on it, but it appears to be a good 1.x - 2.x device with a large enough screen to approximate the variety of screens on different phones). I would wait for Honeycomb equipped devices (such as the Motorola XOOM mentioned at CES 2011), but these are slated for some time in Q1 (likely end of Q1 for the Canadian market). If I get a multitouch capable PC and install the Android SDK and simulator, will I be able to use the multitouch functionality of the PC with the simulator to approximate a real device ? Does anyone use a multitouch touch screen PC for Android development ? I assume that this would work as the PC would recognize my fingers like the mouse, but I'd like to find out before purchasing the PC. Thanks for your help, Scott

  • Book resources for x86/x64 assembly programming on Win platform

    - by Scott Davies
    Hello, I ran a search for assembly language resources on stackoverflow.com and found some interesting results, but they seemed to boil down to two groups: 1) Assembly references to old ia32 architecture, such as the 80386 to Pentium 2) Windows agnostic books. Most of the commenters make the point that assembler is CPU dependent and that the OS is irrelevant, but it seems pointless to me to pick a book that has assembly examples that refer to MS-DOS interrupts and memory layouts. Likewise, learning assembler on Linux would seem to produce Linux executables Are there any: 1) Modern 2) x86/x64 3) on Windows platform - book resources available ? The reason I am targeting the Win platform is I would like to do low-level, OS internals programming, to supplement my Win C/C++ work. Thanks

  • 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?

  • How do you escape double quotes inside a SQL fulltext 'contains' function?

    - by Richard Davies
    How do you escape a double quote character inside a MS SQL 'contains' function? SELECT decision FROM table WHERE CONTAINS(decision, '34" AND wide') Normally contains() expects double quotes to surround an exact phrase to match, but I want to search for an actual double quote character. I've tried escaping it with \, `, and even another double quote, but none of that has worked. P.S. I realize a simple example like this could also be done using the LIKE statement, but I need to use the fulltext search function. The query I provided here has been simplified from my actual query for example purposes.

  • C# (With .NET & Visual Studio) WebForms - How can I get the title of a page ..?

    - by Ashley Davies
    Prety long question; How can I do the following in C#: Open a webpage (Prefferably not visible) Check whether the page redirects to a different page (Site is down, 404, etc.) Check if the title is not equal to a said string Then seperately, (They need to click a confirm button) open their browser, and go to the adress of the first (It'll be the only one) hyperlink on the site. I literally have been looking on google for ages and haven't found anything similar to what I need. Whether you give me a link to a site with a tutorial on this area of programming or actual source code doesn't make a difference to me.

  • JavaScript Prototype and Encapsulation

    - by Adam Davies
    Sorry I'm probably being a realy noob here...but: I have the following javascript object: jeeni.TextField = (function(){ var tagId; privateMethod = function(){ console.log("IN: privateMethod"); } publicMethod = function(){ console.log("IN: publicMethod: " + this.tagId); } jeeni.TextField = function(id){ console.log("Constructor"); this.tagId = id; } jeeni.TextField.prototype = { constructor: jeeni.TextField, foo: publicMethod }; return jeeni.TextField; }()); Now when I run the following code I get the corresponding result: var textField1 = new jeeni.TextField(21); // Outputs: Constructor textField1.foo(); // Outputs: IN: publicMethod: 21 console.log(textField1.tagId); // Outputs: 21 console.log(textField1.privateMethod); // Outputs: undefined So my question is why is privateMethod hidden and tagId is not. I want them both to be private scope. Please help a noob. Thanks

  • NullReferenceException when calling InsertOnSubmit in Linq to Sql.

    - by Charlie
    I'm trying to insert a new object into my database using LINQ to SQL but get a NullReferenceException when I call InsertOnSubmit() in the code snippet below. I'm passing in a derived class called FileUploadAudit, and all properties on the object are set. public void Save(Audit audit) { try { using (ULNDataClassesDataContext dataContext = this.Connection.GetContext()) { if (audit.AuditID > 0) { throw new RepositoryException(RepositoryExceptionCode.EntityAlreadyExists, string.Format("An audit entry with ID {0} already exists and cannot be updated.", audit.AuditID)); } dataContext.Audits.InsertOnSubmit(audit); dataContext.SubmitChanges(); } } catch (Exception ex) { if (ObjectFactory.GetInstance<IExceptionHandler>().HandleException(ex)) { throw; } } } Here's the stack trace: at System.Data.Linq.Table`1.InsertOnSubmit(TEntity entity) at XXXX.XXXX.Repository.AuditRepository.Save(Audit audit) C:\XXXX\AuditRepository.cs:line 25" I've added to the Audit class like this: public partial class Audit { public Audit(string message, ULNComponent component) : this() { this.Message = message; this.DateTimeRecorded = DateTime.Now; this.SetComponent(component); this.ServerName = Environment.MachineName; } public bool IsError { get; set; } public void SetComponent(ULNComponent component) { this.Component = Enum.GetName(typeof(ULNComponent), component); } } And the derived FileUploadAudit looks like this: public class FileUploadAudit : Audit { public FileUploadAudit(string message, ULNComponent component, Guid fileGuid, string originalFilename, string physicalFilename, HttpPostedFileBase postedFile) : base(message, component) { this.FileGuid = fileGuid; this.OriginalFilename = originalFilename; this.PhysicalFileName = physicalFilename; this.PostedFile = postedFile; this.ValidationErrors = new List<string>(); } public Guid FileGuid { get; set; } public string OriginalFilename { get; set; } public string PhysicalFileName { get; set; } public HttpPostedFileBase PostedFile { get; set; } public IList<string> ValidationErrors { get; set; } } Any ideas what the problem is? The closest question I could find to mine is here but my partial Audit class is calling the parameterless constructor in the generated code, and I still get the problem. UPDATE: This problem only occurs when I pass in the derived FileUploadAudit class, the Audit class works fine. The Audit class is generated as a linq to sql class and there are no Properties mapped to database fields in the derived class.

  • WCF <operation>Async methods not generated in proxy interface

    - by Charlie
    I want to use the Asnyc methods rather than the Begin on my WCF service client proxy because I'm updating WPF controls and need to make sure they're being updated from the UI thread. I could use the Dispatcher class to queue items for the UI thread but that's not what I'm asking about.. I've configured the service reference to generate the asynchronous operations, but it only generates the methods in proxy's implementation, not it's interface. The interface only contains syncronous and Begin methods. Why aren't these methods generated in the interface and is there a way to do this, or do I have to create a derived interface to manually add them?

  • ASP.NET web application can't find an assembly

    - by Charlie Somerville
    I deployed an ASP.NET web application last night and I when I woke up this morning it was very slow and would occasionally just throw a 'Service Unavailable' error. I checked the Event Viewer and it was filled up with these errors: I'm puzzled as it was working perfectly when I deployed it (MonoTorrent is required to retrieve the number of seeders/leechers for a certain torrent off the tracker - this was working fine), but it's no longer working and whenever code that uses MonoTorrent gets involved, the worker process just crashes. MonoTorrent.dll is in the /bin/ directory.

  • Javascript event chaining / binding

    - by Charlie Brown
    I have a select list which has a function with a jQuery .post bound on the change() event. <select id="location"> <option value="1"></option> <option value="2"></option> </select> $('#location').change(location_change); function location_change(){ var url = ''; $.post(url, callback); } What I would like to happen is other controls on the page can bind to the $.post callback function like it was an event, so after the location is changed the data is posted back to the server and once the post returns successfully, the subscriber events are fired.

  • Creating a Custom Design-Time Environment

    - by Charlie
    Hello all, My question is related to the design-time support of WPF. From MSDN I read, The WPF Designer provides a framework and a public API which you can use to implement custom adorners, tools, property editors, and designers. But the vast majority of the examples I have found are trivial, and do not illustrate much concerning the creation of a customized designer in an existing WPF application. We have migrated our application from Windows Forms to WPF over the past year, and the next step will be to take an existing WinForms Panel designer, and rewrite it in WPF. Suffice it to say that this will be a huge project. But I don't even know where to begin. I am wondering if any of you have had similar experiences writing a customized designer for a WPF application, and what it was like. Even better, if you could compare and contrast the functionality between the WinForms designer and the WPF designer, or explain the transition from the former to the latter, that would be helpful. If you know of any simple examples that demonstrate a customized design environment (with custom controls, etc.) that would be extremely beneficial. All in all, I am just wondering if many people have undertaken this yet, and what their results have been. EDIT: To clarify, yes, I am talking about hosting a WPF designer. It appears that this may not even be possible, which is a huge setback. Here is a screenshot of our current WinForms designer. As you can see, it is used to create customized user interfaces. You can drag custom controls onto it and design them, then put the panel into a "run mode" in which all of the controls become functional. Short of spending months writing our designer, would this be possible in WPF? What about .NET 4.0 and VS2010? Will those add any designer functionality?

  • What's the best way to debug URLRewrite rules?

    - by Charlie
    Trying to do a few URLRewrite rules - some of them worked, some didn't. For those that didn't work, how do you debug it? Especially if the rule was never invoked, how do I tell where I'm making a mistake? Tried Live HTTP Header extension with firefox as well as checking the server access logs, to no avail. My site is hosted with cpanel, using apache, and the rewrite rules are defined in .htaccess (I have some rules that worked, so it's not a setup issue I'm pretty sure) Thanks

  • How can I mock this asynchronous method?

    - by Charlie
    I have a class that roughly looks like this: public class ViewModel { public ViewModel(IWebService service) { this.WebService = service; } private IWebService WebService{get;set;} private IEnumerable<SomeData> MyData{get;set;} private void GetReferenceData() { this.WebService.BeginGetStaticReferenceData(GetReferenceDataOnComplete, null); } private void GetReferenceDataOnComplete(IAsyncResult result) { this.MyData = this.WebService.EndGetStaticReferenceData(result); } . . . } I want to mock my IWebService interface so that when BeginGetStaticReferenceData is called it is able to call the callback method. I'm using Moq and I can't work out how to do this. My unit test set up code looks something like: //Arrange var service = new Mock<IWebService>(); service.Setup(x => x.BeginGetStaticReferenceData(/*.......don't know.....*/)); service.Setup(x => x.EndGetStaticReferenceData(It.IsAny<IAsyncResult>())).Returns(new List<SomeData>{new SomeData{Name="blah"}}); var viewModel = new ViewModel(service.Object); . .

  • Beginner SEO question on urlrewrite rules

  • WCF Error - The operation has timed out

    - by Charlie.Barker
    We have created a WCF service hosted in a windows service that handles Authentication requests. The only behavior is : ServiceMetadataBehavior smb = new ServiceMetadataBehavior(); smb.HttpGetEnabled = true; selfHost.Description.Behaviors.Add(smb); Our clients are able to authenticate succesfully 10 times then we get the error The operation has timed out When we increase the MaxConcurrentSessions = 50 then our clients can authenticate 50 times before we see the error. Clearly sessions are not being closed after the authentication call is made can anyone tell why this might be happening?

  • Recursive TreeView in ASP.NET

    - by waqasahmed
    I have an object of type list from which I wish to use to populate a treeview in asp.net c#. Each object item has: id | Name | ParentId so for example: id | Name | ParentId ------------------------- 1 | Alice | 0 2 | Bob | 1 3 | Charlie | 1 4 | David | 2 In the above example, the parent would be Alice having two children Bob and Charlie. David is the child of Bob. I have had many problems trying to dynamically populate the treeview recursively in c# ASP.NET Does any one have a simple solution? Btw: you can use People.Id, People.Name and People.ParentId to access the members since it is an object belonging to list. I can post you my code so far (many attempts made) but not sure how useful it will be.

  • Help a C# developer understand: What is a monad?

    - by Charlie Flowers
    There is a lot of talk about monads these days. I have read a few articles / blog posts, but I can't go far enough with their examples to fully grasp the concept. The reason is that monads are a functional language concept, and thus the examples are in languages I haven't worked with (since I haven't used a functional language in depth). I can't grasp the syntax deeply enough to follow the articles fully ... but I can tell there's something worth understanding there. However, I know C# pretty well, including lambda expressions and other functional features. I know C# only has a subset of functional features, and so maybe monads can't be expressed in C#. However, surely it is possible to convey the concept? At least I hope so. Maybe you can present a C# example as a foundation, and then describe what a C# developer would wish he could do from there but can't because the language lacks functional programming features. This would be fantastic, because it would convey the intent and benefits of monads. So here's my question: What is the best explanation you can give of monads to a C# 3 developer? Thanks! (EDIT: By the way, I know there are at least 3 "what is a monad" questions already on SO. However, I face the same problem with them ... so this question is needed imo, because of the C#-developer focus. Thanks.)

  • Find and replace string in MySQL using data from another table

    - by Charlie
    Hi, sorry for formatting this wonky but hope you can understand it. I have two MySql tables, and I want to find and replace text strings in one using data in another. Texts - one column: messages 'thx guys' 'i think u r great' 'thx again' ' u rock' Dictionary - two columns: bad_spelling, good_spelling 'thx' 'thanks' ' u ' ' you ' ' r ' ' are ' I want SQL to go through and look at every row in messages and replace every instance of bad_spelling with good_spelling, and to do this for all the pairs of bad_spelling and good_spelling The closest I have gotten is this: update texts, dictionary set texts.message = replace(texts.message, dictionary.bad_spelling, dictionary.good_spelling) But this only changes 'thx' to 'thanks' (in 2 rows) and does not go on to replace ' u ' with ' you' or ' r ' with ' are '. Any ideas how to make it use all the rows in dictionary in the replace statement? -- PS forgot to mention that this is a small example and in the real thing I will have a lot of find/replace pairs, which may get added to over time.

  • Update panel and usercontrols

    - by Charlie Brown
    I have two web user controls nested inside of an update panel. The events inside the user controls do not appear to trigger the panel. For testing, I have set the method the fires to sleep for 3 seconds, and added an update progress panel to the page. The update progress panel never comes up and the page reflashes as usual. The user controls work correctly and do what they need to do, but I would like to make them ajaxy and pretty. Is there a special method for adding usercontrols to an update so the postback works correctly? <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:UpdateProgress ID="UpdateProgress1" runat="server" DisplayAfter="100"> <ProgressTemplate> UPDATING...</ProgressTemplate> </asp:UpdateProgress> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <div id="order"> <keg:BeerList runat="server" ID="uxBeerList" /> <kegcart:ShoppingCart runat="server" ID="uxCustomerCart" /> <br class="clearfloat" /> </div> </ContentTemplate> </asp:UpdatePanel> Protected Sub uxBeerList_AddItem(ByVal item As KegData.IOrderableItem) Handles uxBeerList.AddItem uxCustomerCart.AddItemToOrder(item) System.Threading.Thread.Sleep(5000) End Sub

  • My PreferenceActivity does not show up, even though it is in my manifest file

  • Setting up java configurations in eclipse..Param files

    - by Charlie
    I'm going to be using ECJ for doing genetic programming and I haven't touched java in years. I'm working on setting up the eclipse environment and I'm catching a few snags. The ECJ source has several packages, and several sample programs come along with it. I ran one sample program (called tutorial1) by going to the run configurations and adding -file pathToParamsFile to the program arguments. This made it point to the params file of that tutorial and run that sample. In a new example I am testing (from the package gui) there are TWO params files. I tried pointing to just one param file and a program ran in the console, but there was supposed to be a GUI which did not load. I'm not sure what I'm doing wrong. Any help would be greaaatly appreciated.
