• WCF Security in a Windows Service

  - by Alphonso

  I have a WCF service which can run as Console App and a Windows Service. I have recently copied the console app up to a W2K3 server with the following security settings: <wsHttpBinding> <binding name="ServiceBinding_Security" transactionFlow="true" > <security mode="TransportWithMessageCredential" > <message clientCredentialType="UserName" /> </security> </binding> </wsHttpBinding> <serviceCredentials> <userNameAuthentication userNamePasswordValidationMode="Custom" customUserNamePasswordValidatorType="Common.CustomUserNameValidator, Common" /> </serviceCredentials> Security works fine with no problems. I have exactly the same code, but running in a windows service and I get the following error when I try to call any of the methods from a client: System.ServiceModel.Security.MessageSecurityException was unhandled Message="An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail." Source="mscorlib" StackTrace: Server stack trace: at System.ServiceModel.Channels.SecurityChannelFactory`1.SecurityRequestChannel.ProcessReply(Message reply, SecurityProtocolCorrelationState correlationState, TimeSpan timeout) ...... (lots of stacktrace info - not very useful) InnerException: System.ServiceModel.FaultException Message="An error occurred when verifying security for the message." The exception tells me nothing. I'm assuming that it has something to do with acces to system resources from the Windows Service. I've tried running it under the same account as the console app, but no luck. Does anyone have any ideas?

• prototype.js equivalent to jquery ajaxSettings cache = true addthis plugin

  - by openstepmedia

  I need help from a prototype.js expert: I'm trying to achieve the following (taken from the addthis forum), and port the solution from jquery to prototype.js (I'm using magento). Original post is here: http://www.addthis.com/forum/viewtopic.php?f=3&t=22217 For the getScript() function, I can create a custom function to load the remote js, however I'm trying to load the js file via the prototype ajax call, and trying to avoid having the script cached in the browser. <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script> <script type="text/javascript"> $(document).ready(function() { $("#changeURL").click(function() { $(".addthis_button").attr("addthis:url","http://www.example.com"); window.addthis.ost = 0; window.addthis.ready(); }); }); // prevent jQuery from appending cache busting string to the end of the URL var cache = jQuery.ajaxSettings.cache; jQuery.ajaxSettings.cache = true; jQuery.getScript('http://s7.addthis.com/js/250/addthis_widget.js'); // Restore jQuery caching setting jQuery.ajaxSettings.cache = cache; </script> <p id="changeURL">Change URL</p> <a class="addthis_button" addthis:url="http://www.google.com"></a> <script type="text/javascript" src="http://s7.addthis.com/js/250/addthis_widget.js#username=rahf"></script>

• Complete list of tools and technologies that make up a solid ASP.NET MVC 2 development environment f

  - by Dr Dork

  This question is related to another wiki I found on SO, but I'd like to develop a more comprehensive example of an automated ASP MVC 2 development environment that can be used to develop and deploy a wide range of small-scale websites by beginners. As far as characteristics of the dev environment go, I'd like to focus on beginner-friendly over powerful since the other wiki focuses more on advanced, powerful setups. This information is targeted for beginners (that already know C# and understand web dev concepts) that have selected... ASP.NET MVC 2 as their dev framework Visual Studio 2010 Pro (or 2008 Pro SP1) as their IDE Windows 7 as their OS and are looking for a quick and easy-to-setup environment that covers managing, building, testing, tracking, and deploying their website with as much automation as possible. A system that can be used for becoming familiar with the whole process, as well as a launching point for exploring other, more custom and powerful systems. Since we've already selected the Compiler, Framework, and OS, I'd like to develop ideas for... Code editor (unless you feel VS will suffice for all areas of code) Database and related tools Unit testing (VS?) Continuous integration build system (VS?) Project Planning Issue tracking Deployment (VS?) Source management (VS?) ASP, C#, VS, and related blogs that beginners can follow Any other categories I'm probably missing Since we're already using Visual Studio, I'd like to focus on the out-of-the-box solutions and features built into Visual Studio, unless you feel there are better solutions that work well with VS and are easier to use than the features built directly into VS. Thanks so much in advance for your wisdom!

• How to Process Lambda Expressions Passed as Argument Into Method - C# .NET 3.5

  - by Sunday Ironfoot

  My knowledge of Lambda expressions is a bit shaky, while I can write code that uses Lambda expressions (aka LINQ), I'm trying to write my own method that takes a few arguments that are of type Lambda Expression. Background: I'm trying to write a method that returns a Tree Collection of objects of type TreeItem from literally ANY other object type. I have the following so far: public class TreeItem { public string Id { get; set; } public string Text { get; set; } public TreeItem Parent { get; protected set; } public IList<TreeItem> Children { get { // Implementation that returns custom TreeItemCollection type } } public static IList<TreeItem> GetTreeFromObject<T>(IList<T> items, Expression<Func<T, string>> id, Expression<Func<T, string>> text, Expression<Func<T, IList<T>>> childProperty) where T : class { foreach (T item in items) { // Errrm!?? What do I do now? } return null; } } ...which can be called via... IList<TreeItem> treeItems = TreeItem.GetTreeFromObject<Category>( categories, c => c.Id, c => c.Name, c => c.ChildCategories); I could replace the Expressions with string values, and just use reflection, but I'm trying to avoid this as I want to make it strongly typed. My reasons for doing this is that I have a control that accepts a List of type TreeItem, whereas I have dozens of different types that are all in a tree like structure, and don't want to write seperate conversion methods for each type (trying to adhere to the DRY principle). Am I going about this the right way? Is there a better way of doing this perhaps?

• How to best transfer large payloads of data using wsHttp with WCF with message security

  - by jpierson

  I have a case where I need to transfer large amounts of serialized object graphs (via NetDataContractSerializer) using WCF using wsHttp. I'm using message security and would like to continue to do so. Using this setup I would like to transfer serialized object graph which can sometimes approach around 300MB or so but when I try to do so I've started seeing a exception of type System.InsufficientMemoryException appear. After a little research it appears that by default in WCF that a result to a service call is contained within a single message by default which contains the serialized data and this data is buffered by default on the server until the whole message is completely written. Thus the memory exception is being caused by the fact that the server is running out of memory resources that it is allowed to allocate because that buffer is full. The two main recommendations that I've come across are to use streaming or chunking to solve this problem however it is not clear to me what that involves and whether either solution is possible with my current setup (wsHttp/NetDataContractSerializer/Message Security). So far I understand that to use streaming message security would not work because message encryption and decryption need to work on the whole set of data and not a partial message. Chunking however sounds like it might be possible however it is not clear to me how it would be done with the other constraints that I've listed. If anybody could offer some guidance on what solutions are available and how to go about implementing it I would greatly appreciate it. Related resources: Chunking Channel How to: Enable Streaming Large attachments over WCF Custom Message Encoder Another spotting of InsufficientMemoryException I'm also interested in any type of compression that could be done on this data but it looks like I would probably be best off doing this at the transport level once I can transition into .NET 4.0 so that the client will automatically support the gzip headers if I understand this properly.

• iPhone SDK: Rendering a CGLayer into an image object

  - by codemercenary

  Hi all, I am trying to add a curved border around an image downloaded and to be displayed in a UITableViewCell. In the large view (ie one image on the screen) I have the following: productImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:product.image]]; [productImageView setAlpha:0.4]; productImageView.frame = CGRectMake(10.0, 30.0, 128.0, 128.0); CALayer *roundedlayer = [productImageView layer]; [roundedlayer setMasksToBounds:YES]; [roundedlayer setCornerRadius:7.0]; [roundedlayer setBorderWidth:2.0]; [roundedlayer setBorderColor:[[UIColor darkGrayColor] CGColor]]; [self addSubview:productImageView]; In the table view cell, to get it to scroll fast, an image needs to be drawn in the drawRect method of a UIView which is then added to a custom cell. so in drawRect - (void)drawRect:(CGRect)rect { ... point = CGPointMake(boundsX + LEFT_COLUMN_OFFSET, UPPER_ROW_TOP); //CALayer *roundedlayer = [productImageView layer]; //[roundedlayer setMasksToBounds:YES]; //[roundedlayer setCornerRadius:7.0]; //[roundedlayer setBorderWidth:2.0]; //[roundedlayer setBorderColor:[[UIColor darkGrayColor] CGColor]]; //[productImageView drawRect:CGRectMake(boundsX + LEFT_COLUMN_OFFSET, UPPER_ROW_TOP, IMAGE_WIDTH, IMAGE_HEIGHT)]; // [productImageView.image drawInRect:CGRectMake(boundsX + LEFT_COLUMN_OFFSET, UPPER_ROW_TOP, IMAGE_WIDTH, IMAGE_HEIGHT)]; So this works well, but if I remove the comment and try to show the rounded CA layer the scrolling goes really slow. To fix this I suppose I would have to render this image context into a different image object, and store this in an array, then set this image as something like: productImageView.image = (UIImage*)[imageArray objectAtIndex:indexPath.row]; My question is "How do I render this layer into an image?" TIA.

• should I use Entity Framework instead of raw ADO.NET

  - by user110182

  I am new to CSLA and Entity Framework. I am creating a new CSLA / Silverlight application that will replace a 12 year old Win32 C++ system. The old system uses a custom DCOM business object library and uses ODBC to get to SQL Server. The new system will not immediately replace the old system -- they must coexist against the same database for years to come. At first I thought EF was the way to go since it is the latest and greatest. After making a small EF model and only 2 CSLA editable root objects (I will eventually have hundreds of objects as my DB has 800+ tables) I am seriously questioning the use of EF. In the current system I have the need many times to do fine detail performance tuning of the queries which I can do because of 100% control of generated SQL. But it seems in EF that so much happens behind the scenes that I lose that control. Article like http://toomanylayers.blogspot.com/2009/01/entity-framework-and-linq-to-sql.html don't help my impression of EF. People seem to like EF because of LINQ to EF but since my criteria is passed between client and server as criteria object it seems like I could build queries just as easily without LINQ. I understand in WCF RIA that there is query projection (or something like that) where I can do client side LINQ which does move to the server before translation into actual SQL so in that case I can see the benefit of EF, but not in CSLA. If I use raw ADO.NET, will I regret my decision 5 years from now? Has anyone else made this choice recently and which way did you go?

• Cannot create list in SharePoint 2010 using Client Object Model

  - by Boris

  I am trying to utilize SharePoint 2010 Client Object Model to create a List based on a custom template. Here's my code: public void MakeList(string title, string listTemplateGUID, int localeIdentifier) { string message; string listUrl; List newList; Guid template; ListCreationInformation listInfo; Microsoft.SharePoint.Client.ListCollection lists; try { listUrl = title.Replace(spaceChar, string.Empty); template = GetListTemplate((uint)localeIdentifier, listTemplateGUID); listInfo = new ListCreationInformation(); listInfo.Url = listUrl; listInfo.Title = title; listInfo.Description = string.Empty; listInfo.TemplateFeatureId = template; listInfo.QuickLaunchOption = QuickLaunchOptions.On; clientContext.Load(site); clientContext.ExecuteQuery(); lists = site.Lists; clientContext.Load(lists); clientContext.ExecuteQuery(); newList = lists.Add(listInfo); clientContext.ExecuteQuery(); } catch (ServerException ex) { //... } } Now, this particular part, newList = lists.Add(listInfo); clientContext.ExecuteQuery(); the one that is supposed to create the actual list, throws an exception: Message: Cannot complete this action. Please try again. ServerErrorCode: 2130239231 ServerErrorTypeName: Microsoft.SharePoint.SPException Could anyone please help me realize what am I doing wrong? Thanks.

• "Unable To Load Client Print Control" - SSRS Printing problems again

  - by mamorgan1

  Please forgive me as my head is spinning. I have tried so many solutions to this issue, that I'm almost not sure where I am at this point. At this point in time I have these issues in my Production, Test, and Dev environments. For simplicity sake, I will just try to get it working in Dev first. Here is my setup: Database/Reporting Server (Same server): Windows Server 2003 SP2 SQL Server 2005 SP3 Development Box: Windows 7 Visual Studio 2008 SP1 SQL Server 2008 SP1 (not being used in this case, but wanted to include it in case it is relative) Internet Explorer 8 Details: * I have a custom ASP.NET application that is using ReportViewer to access reports on my Database/Reporting Server. * I am able to connect directly to Report Manager and print with no trouble. * When I view source on the page with ReportViewer, it says I'm am using version 9.0.30729.4402 . * The classid of the rsclientprint.dll that keeps getting installed to my c:\windows\downloaded program files directory is {41861299-EAB2-4DCC-986C-802AE12AC499}. * I have tried taking the rsclientprint.cab file from my Database/Reporting Server and installing it directly to my Development Box and had no success. I made sure to unregister the previously installed dll first. I feel like I have read as many solutions as I can, and so I turn to you for some assistance. Please let me know if I can provide further details that would be helpful. Thanks

• Reset or clear the UIView from UILabels

  - by Nicsoft

  Hello, I have created an UIView on which I have a number of labels and I'm also drawing some lines in the same UIView. Sometimes I update the lines that I'm drawing. Now, the problem I am having is that when I update the lines, they get drawn according to my wish. But the labels are overwriting themselves. This shouldn't have been a problem if it wasn't for that the position is changed about 1 pixel and that makes the text go blurry. I don't know how to remove the labels before they are redrawn. I do remove the labels from the superview and add them back when drawRect is called, but the SetNeedDisplay doesn't clear the screen before the graphic is updated, I guess (I think I read that SetNeedsDisplay/drawRect doesn't clear the screen, just updating the content. Couldn't find the text now while searching)? What is the pattern to use here, should I create a retangle with the size of the screen (or the area where the labels are) and fill it with the background colour, or is there any other way to clear or reset the UIView (I don't want to release and create the UIView again). The view is created in IB and associated with a custom UIView. In IB I add some buttons and other static labels. The above labels and graphics is created programatically. Any comments would be helpful! Thanks in advance!

• MVC App Works in Visual Studio, but not IIS7

  Working on a an ASP.NET MVC Project, and I'm having some difficulties deploying to a shared dev server. Locally, when debugging using the local Visual Studio 2008 server, everything works peachy.

• serializing type definitions?

  - by Dave

  I'm not positive I'm going about this the right way. I've got a suite of applications that have varying types of output (custom defined types). For example, I might have a type called Widget: Class Widget Public name as String End Class Throughout the course of operation, when a user experiences a certain condition, the application will take that output instance of widget that user received, serialize it, and log it to the database noting the name of the type. Now, I have other applications that do something similar, but instead of dealing with Widget, it could be some totally random other type with different attributes, but again I serialize the instance, log it to the db, and note the name of the type. I have maybe a half dozen different types and don't anticipate too many additional ones in the future. After all this is said and done, I have an admin interface that looks through these logs, and has the ability for the user to view the contents of this data thats been logged. The Admin app has a reference to all the types involved, and with some basic switch case logic hinged upon the name of the type, will cast it into their original types, and pass it on to some handlers that have basic display logic to spit the data back out in a readable format (one display handler for each type) NOW... all this is well and good... Until one day, my model changed. The Widget class now has deprecated the name attribute and added on a bunch of other attributes. I will of course get type mismatches in the admin side when I try to reconstitute this data. I was wondering if there was some way, at runtime, i could perhaps reflect through my code and get a snapshot of the type definition at that precise moment, serialize it, and store it along with the data so that I could somehow use this to reconstitute it in the future?

• Passing binary blob through an Android content provider

  - by velocityb0y

  I have a content provider that is custom to my set of Android applications, and one of the things it needs to expose is a small (20-30k) byte array. The uri for these blobs looks like content://my.authority/blob/# where # is the row number; the resulting cursor has the standard _id column and a data column. I'm using a MatrixCursor in the provider's query method: byte[] byteData = getMyByteData(); MatrixCursor mc = new MatrixCursor(COLUMNS); mc.addRow(new Object[] { id, byteData }); Later, in the application consuming the data, I do Cursor c = managedQuery(uri, null, null, null, null); c.moveToFirst(); byte[] data = c.getBlob(c.getColumnIndexOrThrow("data")); However, data does not contain the contents of my original byte array; rather, it contains something like "[B@435cc518", which looks more like the address of the array than the contents. I tried wrapping the byte array in an implementation of java.sql.Blob, figuring that it might be looking for that since the content provider subsystem was written to be easy to use with SQLite, but it didn't help. Has anyone gotten this to work? If the data was in the file system, there are methods in ContentProvider that I could use to provide a marshalled InputStream to the client, but the data I'm trying to send back lives as a resource in the content provider's APK.

• Static IP for dynamic IP

  - by scape279

  I have a dynamic IP address. I would like to have a static IP, but Virgin Media don't allow static IPs for residential broadband services, even if you ask them really nicely and offer to pay for it without switching to a business tariff. I am already registered with a dynamic DNS service which is updated by my router eg me.example.com will always resolve to my dynamic IP. This is fine for some circumstances, but not if you can only enter an IP address into configuration files/hardware etc like firewalls, subversion services etc etc. Is there a way I can have a static IP address 'forwarding' to my dynamic IP? Would a possible solution involve tunnelling? Setting up a private proxy? Please note the following: I am able to buy an IP address from my web host. I have access to a webserver and I am able to create custom DNS zones. I'm happy to have a webserver running at home if necessary also. I do not wish to change broadband providers. I have zero control over the services that require the IP address entering so I cannot tackle the problem that way round (services I need to access are at work). PS I've tried googling this issue, but it is very difficult to search for as most results are related to dynamic dns (which I already have set up and isnt quite what I'm after)

• UIImagePickerController does nothing when using camera after I hit "Use" button

  - by wgpubs

  Code below. When I hit the "Use" button after taking a picture ... the application becomes totally unresponsive. Any ideas what I'm doing wrong? The "addPlayer:" method is called when a button is pressed on the UIViewController's view. Thanks - (IBAction) addPlayers: (id)sender{ // Show ImagePicker UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; imagePicker.delegate = self; // If camera is available use it and display custom overlay view so that user can add as many pics // as they want without having to go back to parent view if([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera]) { imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera; } else { imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; } [self presentModalViewController:imagePicker animated:YES]; [imagePicker release]; } - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { // Grab original image UIImage *photo = [info objectForKey:UIImagePickerControllerOriginalImage]; // Resize photo first to reduce memory consumption [self.photos addObject:[photo scaleToSize:CGSizeMake(200.0f, 300.0f)]]; // Enable *PLAY* button if photos > 1 if([self.photos count] > 1) btnStartGame.enabled = YES; // Update player count label lblPlayerCount.text = [NSString stringWithFormat:@"%d", [self.photos count]]; // Dismiss picker if not using camera picker dismissModalViewControllerAnimated:YES]; }

• C# Thread Pool Cross-Thread Communication

  - by Goober

  The Scenario I have a windows forms application containing a MAINFORM with a listbox on it. The MAINFORM also has a THREAD POOL that creates new threads and fires them off to do lots of different bits of processing. Whilst each of these different worker threads is doing its job, I want to report this progress back to my MAINFORM, however, I can't because it requires Cross-Thread communication. Progress So far all of the tutorials etc. that I have seen relating to this topic involve custom(ish) threading implementations, whereas I literally have a fairly basic(ish) standard THREAD POOL implementation. Since I don't want to really modify any of my code (since the application runs like a beast with no quarms) - I'm after some advice as to how I can go about doing this cross-thread communication. ALTERNATIVELY - How to implement a different "LOGTOSCREEN" method altogether (obviously still bearing in mind the cross-thread communication thing). WARNING: I use this website at work, where we are locked down to IE6 only, and the javascript thus fails, meaning I cannot click accept on any answers during work, and thus my acceptance rate is low. I can't do anything about it I'm afraid, sorry. EDIT: I DO NOT HAVE INSTALL RIGHTS ON MY COMPUTER AT WORK. I do have firefox but the proxy at work fails when using this site on firefox. FURTHER EDIT: I DO NOT WANT TO CHANGE MY THREADING IMPLEMENTATION. AT ALL! - Accept to enable cross-thread communication....why would a backgroundworker help here!?

• jQuery AJAX slow in Firefox, fast in IE

  - by Brandon Montgomery

  I'm using jQuery to post to an ASP .NET Web Service to implement a custom auto-complete function. The code works great, except it's slow in FireFox (can't get it to go faster than 1 second). IE is blazing fast - works great. I watch the post in Firefox using Firebug. Here's the service code: <ScriptService(), _ WebService(Namespace:="http://tempuri.org/"), _ WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1), _ ToolboxItem(False)> _ Public Class TestWebSvc Inherits System.Web.Services.WebService <WebMethod(), _ ScriptMethod(ResponseFormat:=Script.Services.ResponseFormat.Json, UseHttpGet:=True)> _ Public Function GetAccounts(ByVal q As String) As Object 'Code taken out for simplicity Return result End Function End Class And the jQuery ajax call: $.ajax({ beforeSend: function (req) { req.setRequestHeader("Content-Type", "application/json"); }, contentType: "application/json; charset=utf-8", type: "GET", url: "http://localhost/Suggest/TestWebSvc.asmx/GetAccounts", data: "q='" + element.val() + "'", dataType: "json", success: testWebSvcSuccess }); As you can see, I've tried to use the HTTP GET verb instead in hopes that that would make the call faster. As it does not, I'll probably switch it back to using POST if I can. Right now I'm just focused on why it's super fast in IE and super slow in Firefox. Versions: jQuery 1.3.2; Firefox 3.0.11; IE 8.0.6001.18783 (64-bit) Thank you for any insight you can provide.

• Complex Types, ModelBinders and Interfaces

  - by Kieron

  Hi, I've a scenario where I need to bind to an interface - in order to create the correct type, I've got a custom model binder that knows how to create the correct concrete type (which can differ). However, the type created never has the fields correctly filled in. I know I'm missing something blindingly simple here, but can anyone tell me why or at least what I need to do for the model binder to carry on it's work and bind the properties? public class ProductModelBinder : DefaultModelBinder { override public object BindModel (ControllerContext controllerContext, ModelBindingContext bindingContext) { if (bindingContext.ModelType == typeof (IProduct)) { var content = GetProduct (bindingContext); return content; } var result = base.BindModel (controllerContext, bindingContext); return result; } IProduct GetProduct (ModelBindingContext bindingContext) { var idProvider = bindingContext.ValueProvider.GetValue ("Id"); var id = (Guid)idProvider.ConvertTo (typeof (Guid)); var repository = RepositoryFactory.GetRepository<IProductRepository> (); var product = repository.Get (id); return product; } } The Model in my case is a complex type that has an IProduct property, and it's those values I need filled in. Model: [ProductBinder] public class Edit : IProductModel { public Guid Id { get; set; } public byte[] Version { get; set; } public IProduct Product { get; set; } }

• C#: How to force "calling" a method from the main thread by signaling in some way from another thread

  - by Fire-Dragon-DoL

  Sorry for long title, I don't know even the way on how to express the question I'm using a library which run a callback from a different context from the main thread (is a C Library), I created the callback in C# and when gets called I would like to just raise an event. However because I don't know what will be inside the event, I would like to find a way to invoke the method without the problem of locks and so on (otherwise the third party user will have to handle this inside the event, very ugly) Are there any way to do this? I can be totally on the wrong way but I'm thinking about winforms way to handle different threads (the .Invoke thing) Otherwise I can send a message to the message loop of the window, but I don't know a lot about message passing and if I can send "custom" messages like this Example: private uint lgLcdOnConfigureCB(int connection, System.IntPtr pContext) { OnConfigure(EventArgs.Empty); return 0U; } this callback is called from another program which I don't have control over, I would like to run OnConfigure method in the main thread (the one that handles my winform), how to do it? Or in other words, I would like to run OnConfigure without the need of thinking about locks

• Using Freepascal\Lazarus JSON Libraries

  - by Gizmo_the_Great

  I'm hoping for a bit of a "simpletons" demo\explanation for using Lazarus\Freepascal JSON parsing. I've asked a question here but all the replies are "read this" and none of them are really helping me get a grasp because the examples are bit too in-depth and I'm seeking a very simple example to help me understand how it works. In brief, my program reads an untyped binary file in chunks of 4096 bytes. The raw data then gets converted to ASCII and stored in a string. It then goes through the variable looking for certain patterns, which, it turned out, are JSON data structures. I've currently coded the parsing the hard way using Pos and ExtractANSIString etc. But I'vesince learnt that there are JSON libraries for Lazarus & FPC, namely fcl-json, fpjson, jsonparser, jsonscanner etc. https://bitbucket.org/reiniero/fpctwit/src http://fossies.org/unix/misc/fpcbuild-2.6.0.tar.gz:a/fpcbuild-2.6.0/fpcsrc/packages/fcl-json/src/ http://svn.freepascal.org/cgi-bin/viewvc.cgi/trunk/packages/fcl-json/examples/ However, I still can't quite work out HOW I read my string variable and parse it for JSON data and then access those JSON structures. Can anyone give me a very simple example, to help getting me going? My code so far (without JSON) is something like this: try SourceFile.Position := 0; while TotalBytesRead < SourceFile.Size do begin BytesRead := SourceFile.Read(Buffer,sizeof(Buffer)); inc(TotalBytesRead, BytesRead); StringContent := StripNonAsciiExceptCRLF(Buffer); // A custom function to strip out binary garbage leaving just ASCII readable text if Pos('MySearchValue', StringContent) > 0 then begin // Do the parsing. This is where I need to do the JSON stuff ...

However I can see the code for the grid in the designer file. Any pointer on this would be a great help.

• Navigating through a sea of hype

  - by wouldLikeACrystalBall

  This is a vague, open question, so if you have no interest in these, please leave now. A few years ago it seemed everyone thought the death of desktop software was imminent. Web applications were the future. Everyone would move to cloud-based software-as-a-service systems, and developing applications for specific end-user platforms like Windows would soon become something of a ghetto. Joel's "How Microsoft Lost the API War" was but one of many such pieces sounding the death knell for this way of software development. Flash-forward to 2010, and the hype is all around mobile devices, particularly the iPhone. Software-as-a-Service vendors--even small ones such as YCombinator startups--go out of their way to build custom applications for the iPhone and other smart phone devices; applications that can be quite sophisticated, that run only on specific hardware and software architectures and are thus inherently incompatible. Now some of you are probably thinking, "Well, only the decline of desktop software was predicted; mobile devices aren't desktops." But the term was used by those predicting its demise to mean laptops also, and really any platform capable of running a browser. What was promised was a world where HTML and related standards would supplant native applications and their inherent difficulties. We would all code to the browser, not the OS. But here we are in 2010 with the AppStore bulging and development for the iPad just revving up. A few days ago, I saw someone on Hacker News claim that the future of computing was entirely in small, portable devices. Apparently the future is underpowered, requires dexterous thumbs and induces near-sightedness. How do those who so vehemently asserted one thing now assert the opposite with equal vehemence, without making even the slightest admission of error? And further, how are we as developers supposed to sift through all of this? I bought into the whole web-standards utopianism that was in vogue back in '06-'07 and now feel like it was a mistake. Is there some formula one can apply rather than a mere appeal to experience?

• iPhone TableView alternative options for Check Mark Accessory

  - by jimsis

  I'm looking for the best approach to this problem. In my tableview I have a list of options from which you can select one and only one. The problem is the selection to choose is not obvious without displaying more details on the option. If I use the disclosure indicator or button for the more detail, I lose the checkmark functionality. In searching around I see some have used the cell Image as a work around. I see others instead of using the standard disclosure button have created custom disclosure button looking like a checkmark. Haven't seen this one but is it viable (HIG) to add a button in the cell ('more info') to launch the next tableview. My thought was to use a disclosure indicator and on the second view in the navigation bar (where the edit button usually is) add a 'selectMe' button. I think I am probably manage to code either of the above, am just asking for information on what is the best (HIG) way. Example Option 1 Option 2 Option 3 (x) Option 4 Where x is the checked one But in order to know which is the best choice you need to see Option 3 (Header) Option 3-a Option 3-b Option 3-c Option 3-d Where even at this level option 3-c might have additional information. Any guidance you can provide would appreciated.
