  • iPhone app running in Instruments fails with unrecognized selector

    - by Mark Smith
    I have an app that appears to run without problems in normal use. The Clang Static Analyzer reports no problems either. When I try to run it in Instruments, it fails with an unrecognized selector exception. The offending line is a simple property setter of the form: self.bar = baz; To figure out what's going on, I added an NSLog() call immediately above it: NSLog(@"class = %@ responds = %d", [self class], [self respondsToSelector:@selector(setBar:)]); self.bar = baz; On the emulator (without Instruments) and on a device, this shows exactly what I'd expect: class = Foo responds = 1 When running under Instruments, I get: class = Foo responds = 0 I'm stumped as to what could cause this. Perhaps a different memory location is getting tromped on when it's in the Instruments environment? Can anyone suggest how I might debug this?

  • EnvDTE: ArgumentException when accessing the ActiveConfiguration

    - by Smith
    Hello, I'm writing an addin for Visual Studio 2008. At some point in my code, I'm attempting to access the current active configuration for a project: var configName = _Project.ConfigurationManager.ActiveConfiguration.ConfigurationName; Sometimes, in some very obscure cases, the getter for ActiveConfiguration throws an ArgumentException. Nothing in the documentation says anything about this (but given the very poor quality of the documentation, it was to be expected), and the exception's message is not helping at all. Also, ConfigurationManager is an interface, and I don't know what's the real implementation behind it, so I can't simply disassemble it in Reflector to know the cause. Any help would be greatly appreciated.

  • Workflows not starting after fresh install

    - by Greg McGuffey
    I just installed Dynamics CRM 4.0. It is working nicely except for workflows. They won't start. I turned on tracing and it appears that there is an IO error. The server is setup with IFD and SSL. No issues accessing it internally or externally. Here is the trace: # CRM Tracing Version 2.0 # LocalTime: 2010-06-08 11:34:58.2 # Categories: # CallStackOn: No # ComputerName: FOX-CRM1 # CRMVersion: 4.0.7333.2741 # DeploymentType: OnPremise # ScaleGroup: # ServerRole: AppServer, AsyncService, DiscoveryService, WebService, ApiServer, HelpServer, DeploymentService [2010-06-08 11:34:58.2] Process:CrmAsyncService |Organization:821a137e-7191-49a4-86cc-69101e2b6d20 |Thread: 24 |Category: Platform.Async |User: 00000000-0000-0000-0000-000000000000 |Level: Error | AsyncOperationCommand.Execute >Exception while trying to execute AsyncOperationId: {DF68F483-2C73-DF11-9A34-18A9053B7B38} AsyncOperationType: 1 - System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. ---> System.IO.IOException: The handshake failed due to an unexpected packet format. at System.Net.Security.SslState.StartReadFrame(Byte[] buffer, Int32 readBytes, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.StartReceiveBlob(Byte[] buffer, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.CheckCompletionBeforeNextReceive(ProtocolToken message, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.StartSendBlob(Byte[] incoming, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.ForceAuthentication(Boolean receiveFirst, Byte[] buffer, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.ProcessAuthentication(LazyAsyncResult lazyResult) at System.Net.TlsStream.CallProcessAuthentication(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Net.TlsStream.ProcessAuthentication(LazyAsyncResult result) at System.Net.TlsStream.Write(Byte[] buffer, Int32 offset, Int32 size) at System.Net.PooledStream.Write(Byte[] buffer, Int32 offset, Int32 size) at System.Net.ConnectStream.WriteHeaders(Boolean async) --- End of inner exception stack trace --- at System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.HttpWebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at Microsoft.Crm.SdkTypeProxy.CrmService.Retrieve(String entityName, Guid id, ColumnSetBase columnSet) at Microsoft.Crm.Asynchronous.SdkTypeProxyCrmServiceWrapper.Retrieve(String entityName, Guid id, ColumnSetBase columnSet) at Microsoft.Crm.Asynchronous.SdkPluginDescriptionProvider.GetPluginTypeDescription(Guid pluginTypeId, IOrganizationContext context) at Microsoft.Crm.Caching.PluginTypeCacheLoader.LoadCacheData(Guid key, IOrganizationContext context) at Microsoft.Crm.Caching.CrmMultiOrgCache`2.CreateEntry(TKey key, IOrganizationContext context) at Microsoft.Crm.Caching.CrmSharedMultiOrgCache`2.LookupEntry(TKey key, IOrganizationContext context) at Microsoft.Crm.Caching.PluginTypeCache.LookupEntry(Guid pluginTypeId, IOrganizationContext context) at Microsoft.Crm.Asynchronous.AsyncOperationCommand.GetPluginType(Guid pluginTypeId) at Microsoft.Crm.Asynchronous.EventOperation.InternalExecute(AsyncEvent asyncEvent) at Microsoft.Crm.Asynchronous.AsyncOperationCommand.Execute(AsyncEvent asyncEvent) The only thing I've tried to to update the AsyncSdkRootDomain row in the Deployment table to match the ADSdkRootDomain and the ADApplicationRootDomain values.

If this is correct, how would one configure a CRM server for secure access, internal and external (IFD) and still allow asynch service to hit web site? Thanks for your help!

  • Using Timthumb to Resize Images from CKEditor

    - by Edward Coleridge Smith
    I am using CKEditor to do basic text and image input into my website. I have noticed that it is quite sporadic in it's method of generating HTML for images when you add them. (Sometimes it might use height and width tags, other times it might use CSS). I use Timthumb for on the fly image resizing on a number of other websites and find it very useful. I use a mod_rewrite rule in my .htaccess file to allow me to create domains like http://localhost/images/800x600/image.jpg and achieve resizing. I would like to somehow incorporate this into CKEditor. I cannot find how to do this looking through the documentation so I have tried post-processing the data produced by CKEditor using Regex, however as mentioned before CKEditor seems to be too sporadic to be able to get this to work all the time. Anyone else done this before? How did you achieve it?

  • is (StringComparison.)Ordinal the same as InvariantCulture for testing equality?

    - by Tim Lovell-Smith
    From what I read so far, it sounds like these StringComparison types are meant to differ in how they do sorting of strings, if so, does that mean that it does'nt matter which StringComparison you use when doing an equality comparison? string.Equals(a, b, StringComparison....) Extra credit: does it make a difference to the answer if we compare OrdinalIgnoreCase and InvariantCultureIgnoreCase? What is the answer then? Please provide supporting argument and/or references.

  • E-commerce platform for custom application integration

    - by Zach Smith
    We are building an online subscription-based website and I'm looking for recommendations on which e-commerce platform to use for the checkout process. Requirements include: Only four products. The sign-up process of the site is heavily customized, and after checkout the user should automatically get logged into the subscriber area. Subscriptions will last one year and can be renewed manually. Support for coupons/discount codes at a later point. Since the entire application is custom, we've weighed building a custom checkout but are strongly leaning towards using existing software to avoid having to build lots of admin reporting as well as a coupon engine down the road. The two questions we're pondering are: Is it better to a) build our application custom and use whatever e-commerce software we select just for the payment piece, or b) use the e-commerce software as the basis and build our application around it/as a module/etc? Which e-commerce platform should we use? I've looked into a variety of off the shelf e-commerce software, but it's not clear to me which would be easiest to integrate with. I've researched on the Web and looked at many of the threads on SO to compiled a list of potential candidates: www.magentocommerce.com/ (seems difficult to integrate with) www.prestashop.com/ www.nopcommerce.com/ www.opencart.com/ www.cubecart.com/ www.spreecommerce.com/ www.interspire.com/ www.tradingeye.com/ We're most concerned with the level of effort required with ramping up on the software and then doing the integration with our custom functionality. We're most proficient with PHP, ASP.NET and some ROR and are only considering those technologies. We prefer open source, but would be open to commercial if there's a significant upside. Any experiences with similar projects and advice is greatly appreciated.

  • converting JSON to an object / dictionary / dynamic

    - by benpage
    I'm currently using jqGrid to display data. Part of jqGrid's interface will give you search options, posting back the search details in a JSON string, for example: {"groupOp":"AND","rules":[{"field":"PersonID","op":"eq","data":"123"},{"field":"LastName","op":"eq","data":"Smith"}]} (meaning i'm searching for personID = 123, and LastName = 'Smith') so what i'm hoping to do is somehow convert that back into something i can use server-side. Does anyone have a solution for this that may convert it back into an object of some kind? My current solution would be to convert into xml, parse with linq and create instances of my own 'search' class with a 'rules' collection.

  • CATiledLayer blanking tiles before drawing contents

    - by Greg Plesur
    All, I'm having trouble getting behavior that I want from CATiledLayer. Is there a way that I can trigger the tiles to redraw without having the side-effect that their areas are cleared to white first? I've already subclassed CATiledLayer to set fadeDuration to return 0. To be more specific, here are the details of what I'm seeing and what I'm trying to achieve: I have a UIScrollView with a big content size...~12000x800. Its content view is a UIView backed by a CATiledLayer. The UIView is rendered with a lot of custom-drawn lines Everything works fine, but the contents of the UIView sometimes change. When that happens, I'd like to redraw the tiles as seamlessly as possible. When I use setNeedsDisplay on the view, the tiles redraw but they are first cleared to white and there's a fraction-of-a-second delay before the new content is drawn. I've already subclassed CATiledLayer so that fadeDuration is set to 0. The behavior that I want seems like it should be possible...when you zoom in on the scrollview and the content gets redrawn at a higher resolution, there's no blanking before the redraw; the new content is drawn right on top of the old one. That's what I'm looking for. Thanks; I appreciate your ideas. Update: Just to follow up - I realized that the tiles weren't being cleared to white before the redraw, they're being taken out entirely; the white that I was seeing is the color of the view that's beneath my CATiledLayer-backed view. As a quick hack/fix, I put a UIImageView beneath the UIScrollView, and before triggering a redraw of the CATiledLayer-backed view I render its visible section into the UIImageView and let it show. This smooths out the redraw significantly. If anyone has a better solution, like keeping the redraw-targeted tiles from going away before being redrawn in the first place, I'd still love to hear it.

  • WPF ComboBox TemplateBinding to selected value

    - by Greg R
    I'm trying to create an editable textbox via a drop down of selected values. Basically in Red Only mode I want the drop down to be a disabled textbox. It works fine when I do this with SelectedValue but when I need it to display the dropdown text and not the value. This is what I have: <Style x:Key="EditableDropDownValueOnly" TargetType="ComboBox"> <Setter Property="Width" Value="Auto" /> <Setter Property="FontSize" Value="11" /> <Setter Property="HorizontalAlignment" Value="Left" /> <Setter Property="FontFamily" Value="Verdana" /> <Setter Property="MinWidth" Value="25" /> <Style.Triggers> <Trigger Property="IsReadOnly" Value="True"> <Setter Property="Background" Value="#FFFFFF" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ComboBox"> <TextBox Text="{TemplateBinding SelectedItem, Converter={StaticResource StringCaseConverter}}" BorderThickness="0" Background="Transparent" FontSize="{TemplateBinding FontSize}" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" FontFamily="{TemplateBinding FontFamily}" Width="{TemplateBinding Width}" TextWrapping="Wrap"/> </ControlTemplate> </Setter.Value> </Setter> </Trigger> </Style.Triggers> </Style> SelectedItem is a KeyValuePair, since my drop down is bound to a dictionary. I'm trying to display the "Value" element in my template. Is that possible? Thanks a lot!

  • How can I hot deploy using the glassfish adapter in Eclipse

    - by Greg
    Has anyone gotten the glassfish v3 adapter to work with Eclipse without restarting every time there's a code change? I tried to set this up but the adapter "republishes" every time I change any file, which is very annoying. It takes up to 3 minutes and locks up my machine for a second. I must remember to constantly stop the adapter before making any changes. I'd settle for just disabling this "feature", but even if I uncheck "publish change immediately" this behavior still happens. I'm using the latest version of the glassfish adapter and tried with eclipse 3.5 and the 3.6 milestone builds.... What setup is everyone using if you have glassfish v3 as your server? Is there any way to actually get the hot deploy feature to work correctly?

    Hi I'd like to know how to make that "iif" work. Basically, I need to filter the engineering "product codes" when originator is "John Smith". currentmember is not working or that iif is not working, SELECT { ( [Time].[Fiscal Hierarchy Time Calculations].[Month to Date], [Measures].[Sell - Bookings] ) } ON COLUMNS, [Originators].[Originator One Letter Name].Children ON ROWS FROM [Sales] WHERE ( [Time].[Fiscal Month].&[2010-02-01T00:00:00], IIF ( [Originators].[Originator One Letter Name].CurrentMember = "John Smith", Except ( [Product Codes].[Product Primary Subcategory].Children, [Product Codes].[Product Primary Subcategory].&[ENGINEERING] ), [Product Codes].[Product Primary Subcategory].Children ) ); Any ideas? Thanks in advance. Duy

  • How does the timeout work in Restlet's client class?

    - by Greg Noe
    Here's some code: Client client = new Client(Protocol.HTTP); client.setConnectTimeout(1); //milliseconds Response response = client.post(url, paramRepresentation); System.out.println("timed out"); What I would expect to happen is that it prints "timed out" before the resource has time to process. Instead, nothing happens with the timeout and it doesn't print "timed out" until after the resource returns. Even if I put a Thread.sleep(5000) at the resource that's handling the request, the entire sleep is performed, like the timeout did nothing. Anyone have experience with this? I'm using Restlet 1.1.1. Thanks.

  • How can I schedule tasks in a WinForms app?

    - by Greg
    QUESTION: How can I schedule tasks in a WinForms app? That is either (a) what is the best approach / .NET classes/methods to use of (b) if there is an open source component that does this well which one would be recommended. BACKGROUND: Winforms app (.NET v3.5, C#, VS2008) I'm assuming I will run the winforms application always, and just minimise to the system tray when not in use Want a simple approach (didn't want to get into separate service running that UI winforms app talks to etc) Want to be able to let the user select how often to schedule the sync (e.g. hourly, daily - pick time, etc) Ability to at the times when the scheduler fires to run a chunk of code (assume it could be wrapped as a backgroundworker task for example) The application is always running & appears in the system tray

  • Majordomo/Mailman - Yahoo/Google Groups

    - by tom smith
    Hi. Not an app question, but thought that I might ask here anyway! The responses might help someone. I've got an app where we're going to be dealing with 5000-10000 people in a group/pool. Periodically, different subsets of people will break off in their own group. I'm looking for thoughts on how to manage/approach this situation. (For now, all of this is being managed on a few servers in the garage, with dynamic IP) I've looked into the Yahoo/google groups, and they seem to be reasonable. The primary issue that I see with this approach, is that I don't have a good way of quickly/easily alowing a subset of the group to form their own group for a given project. This kind of function is critical. The upside to this though, I wouldn't have to really set anything up. And the hosted groups could send emails to the user all day along, without running into cap/bandwidth limits The other approach is a managed list, like mailman/majordomo. This approach appears to be more flexible, and looks like ti could be modified to handle the quick creation of lists, allowing users to quickly be assigned to different lists on the fly.. The downside, I'd have to run my own Mailman/Majordomo instance, as well as the associated mail server. Or I could look at possibly using one of the hosted service.. But this is for a project on the cheap, so we're really trying to keep costs down. Thoughts/Comments/Pointers would be greatly appreciated. Thanks in advance -tom

  • .NET: understanding web.config in asp.net

    - by mark smith
    Hi there, Does anyone know of a good link to explain how to use the web.config...... For example, i am using forms authentication... and i notice there is a system.web and then it closed /system.web and then below configuration there are additional location tags here is an example, if you ntoice there is an authentication mode=forms with authorization i presume this is the ROOT....... It is also self contained within a system.web .... Below this there are more location= with system.web tags.... I have never really understand what i am actually doing.. I have tried checkign the MSDN documentation but still i don't fully understand up.... Can anyone help? If you notice with my example.... everything is stored in 1 web.config... i thought the standard waas create a standard web.config and then create another web.config in the directory where i wish to protect it..??? <configuration> <system.web> <compilation debug="true" strict="false" explicit="true" targetFramework="4.0" /> <authentication mode="Forms"> <forms loginUrl="Login.aspx" defaultUrl="Login.aspx" cookieless="UseCookies" timeout="60"/> </authentication> <authorization> <allow users="*"/> </authorization> </system.web> <location path="Forms"> <system.web> <authorization> <deny users="?"/> <allow users="*"/> </authorization> </system.web> </location> <location path="Forms/Seguridad"> <system.web> <authorization> <allow roles="Administrador"/> <deny users="?"/> </authorization> </system.web> </location>

  • Winforms-how do I keep window fully painted/responsive during a long running synchronous request is

    - by Greg
    Hi, Background - For a winforms 3.5 c# application, I would like to keep the main window fully painted/responsive during a long running synchronous request. For example if the user moves the window. Question - Is there a way to achive this WITHOUT having to setup a separate thread or backgroundworker process? (e.g. like a way to call from within my long running transaction, "release a bit of CPU to mainform", at some points) thanks

  • Any sample C# project that highlights separate data access layer (using EF) to business logic layer

    - by Greg
    Hi, I'm interested in having a look at a small sample project that would highlight a good technique to separate data access layer (using Entity Framework) to business logic layer. In C# would be good. That is, it would highlight how to pass data between the layer without coupling them. That is, the assumption here is not to use the EF classes in the Business Logic layer, and how to achieve this low coupling, but minimizing plumbing code.

  • If url exists Objective-c

    - by HiGuy Smith
    Hey, I have a program that needs to tell if an online image exists, but the only way that I've gotten this to work is by loading the image in a NSData pointer and checking if the pointer exists. - (BOOL)exists { NSString *filePath = @"http://couleeapps.hostei.com/BottomBox.png"; NSURL *url = [NSURL URLWithString:filePath]; NSData *imageData = [NSData dataWithContentsOfURL:url]; if (imageData) { return YES; } return NO; } This has worked for me, but my problem is that I have a very slow connection, and it takes forever to download the image. So my question is: is there a way to check if a image (say "http://couleeapps.hostei.com/BottomBox.png") is available without having to download it? Help is much appreciated HiGuy

  • In separate data access & business logic layer, can I use Entity framework classes in business layer

    - by Greg
    In separate data access & business logic layer, can I use Entity framework classes in business layer? EDIT: I don't think I will need to swap out the data access layer from my business logic in the future (i.e. will be SQL Server), however I will for the UI layer. Therefore the question is more meant to be are there any major issues with using EF classes for me in the business layer? Seems like there would be less plumbing code.
