Thanks.

  • How do I detect the environment in Salesforce?

    - by Craig Harris
    I am integrating our back end systems with Salesforce using the web services. I have production and stage environments running on different URLs. I need to be able to have the endpoint of the web service call be different depending on whether the code is running in the production or sandbox Salesforce instance. How do I detect the environment. Currently I am considering looking up a user to see if there user name ends in 'devsandbox' as I have been unable to identify a system object that I can query to get the environment. Further clarification: The location I need to determine this is within the Apex code that is invoked when I select a button in Salesforce. My custom controller needs to know if it running in the production or sandbox Salesforce environment.

  • Using attribute text value in AngularJS directive

    - by C1pher
    Using a YouTube tutorial created by John Lindquist, I was able to create a directive using a template. See fiddle: http://jsfiddle.net/37PSs/ Now, I want to use the value of the attribute as a variable to a function call. Something like this: html: <hello-world name="World"></hello-world> javascript - directive: template: '<span>myFunction({{name}})</span>' javascript - myFunction(theirName): return ("Hello, " + String(theirName) + "!"); The closest I've been able to get is passing an [object Window] to my function.

  • recaptcha asp.net always returns invalid

    - by Curtis White
    The reCaptcha example for ASP.NET does not seem to work. I followed the instructions but it always returns false, "The verification words are incorrect.". The entries are good. I'm using localhost as the site but am not getting any public/private key errors which I did get when adding a bad key (as a test). I've seen this error reported a lot but no good answers. Some suggest to call the validate on the control before checking to see if it is valid but this did not work for me.

  • Will the following code be Garbage Collected before the class "dies"?

    - by devoured elysium
    Let's say we have the following code in a class: //class code TextBox t = new TextBox(); ListBox l = new ListBox(); We have then two possible situations: In the first, we declare qem1 as a class variable(or attribute, as they call it in the Java World): //class variable QuickEntryMediator qem1 = new QuickEntryMediator(t,l); In the second, we declare it inside a method: //method variable QuickEntryMediator qem2 = new QuickEntryMediator(t,l); So, I'd say qem1 would never be Garbage Collected before the class goes out of scope while in the qem2 might be Garbage Collected at any time after the method in which it resides dies. Is this true? I am looking for answers for both C#(.net) and Java, as am I am not sure both GC's work in the same fashion! Thanks

  • Invoking MSYS bash from Windows cmd

    - by daevius
    I'm using GCC on Windows7 (using the TDM's build). I installed MSYS to be able to execute make and compile using makefiles. However, it is tedious to every time start up the MSYS bash shell, navigate to the directory of the project and run make. What I want is to automate this process. I prefer to have a batch file in Windows, or something similar, from which I then invoke the MSYS bash. It should navigate to the directory the batch file resides in and call "make". Is this possible? Can I send commands to MSYS bash from cmd (like navigation / invoking make)? Or can I let the MSYS bash run a "bash script", which sets the commands to be executed much like batch scripts? Thank you. PS: this is something similar as this question: http://stackoverflow.com/questions/2546757/executing-msys-from-cmd-exe-with-arguments

  • How to verify an XML digital signature in Cocoa?

    - by Geoff Smith
    I have a C# application that uses XML digital signatures to sign license files. I've used the standard Microsoft approach described here. I'm porting the application to the MAC and need to verify the signature. My general question is how best to do this? This is what I've done: I've used macport to install Aleksey's xmlsec1 library. Used the Chilkat library to convert my XML public key to a PEM file Chilkat.PublicKey pubKey = new Chilkat.PublicKey(); pubKey.LoadXml(publicKeyXml); pubKey.SaveOpenSslPemFile("publicKey.pem"); Compiled and ran the alekseys sample program. See (http://www.aleksey.com/xmlsec/api/xmlsec-verify-with-key.html) to verify an XML dsig. Result: my license files fail to validate. The call to xmlSecDSigCtxVerify fails with status=unknown. Now for my specific question: What can I do next? Geoff

  • Android AccountManager API

    - by Steph
    Hi everyone, I'm struggling to understand the Android AccountManager API. As far as I got thinks working I can use the blockingGetAuthToken method and specify whether Android should provide a notification for user to allow or deny the request. Another possibility is to use getAuthToken and check if KEY_INTENT is returned. If that's the case I could start a new Activity where the user can confirm my request. My problem is that I would like to call one of these two methods from within a Service. Is there any chance to get a callback once the user has made a decision? Thanks for your help

  • How do I check if a swf file loaded correctly since put_Movie always returns S_OK?

    - by Tim
    I am using the latest flash player and have a swf file served locally from my dev machine. In one container test app I am able to play the swf and make calls to it, but in my "Real" application the same code path results in com errors (basically it looks like the swf isn;' loading properly) Additionally this is made more challenging because no matter what nonsense I put in the call to put_Movie() the return is ALWAYS S_OK. This is confusing. How am I supposed to determine if the swf file loaded and is working? As a follow-on, what would cause a swf file (the same one) not to load in a different app? The code paths are the same (from what I can tell). Obviousl something is going on, but I am not sure what. So, I guess 2 questions How to know when swf file doesn't load right Why might it fail in a different container application? I am using ATL in Visual studio 2008, latest flash, MS Vista Thanks

  • ASP.NET MVC ,Maintaining Model State between Ajax requests

    - by Podders
    problem: On first full page request, my controller invokes an applicationServices Layer (Web Service Proxy to my business tier) in order to populate a collection of current services that is stored in my own controller base class property. This is then to be displayed within a view. Everything within the context of that controller has access to this "Services Collection". Now when i make further calls to the same action method via an AJAX Call, i obviously hitt a different instance of that controller meaning my services collection is empty. So other than re-getting the whole collection again, where would i store this collection so it gets persisted between ajax requests? Should i persist it as a seperate DomainModel Object, Session object?....as ViewData is not working for me obv. Excuse my MVC ignorance :) Any help would be greatly appreciated :)

  • How to combine template partial specialization and template argument deduction

    - by KKKoo0
    My understanding is that template argument deduction is only for function templates, but function templates does not allow partial specialization. Is there a way to achieve both? I basically want to achieve a function-like object (can be a functor) with the signature template<class InputIterator1, class InputIterator2, class OutputIterator, int distribution> void GetQuantity(InputIterator1 frist1, InputIterator1 last1, InputIterator2 first2, OutputIterator result, double supply, double limit); Depending on the value of distribution, I want to have a couple of specializations of this template. And when I call this function,I basically do not want to specify all the type parameters, because they are many of them (and thus I need argument deduction)!

  • LINQ To Entities - Items, ItemCategories & Tags

    - by Simon
    Hi There, I have an Entity Model that has Items, which can belong to one or more categories, and which can have one or more tags. I need to write a query that finds all tags for a given ItemCategory, preferably with a single call to the database, as this is going to get called fairly often. I currently have: Dim q = (From ic In mContext.ItemCategory _ Where ic.CategoryID = forCategoryID _ Select ic).SelectMany(Function(cat) cat.Items).SelectMany(Function(i) i.Tags) _ .OrderByDescending(Function(t) t.Items.Count).ToList This is nearly there, apart from it doesn't contain the items for each tag, so I'd have to iterate through, loading the item reference to find out how many items each tag is related to (for font sizing). Ideally, I want to return a List(Of TagCount), which is just a structure, containing Tag as string, and Count as integer. I've looked at Group and Join, but I'm not getting anywhere so any help would be greatly appreciated!

  • Finding zoom level from window object properties

    - by Mihai Fonoage
    Hi, I want to find out the zoom level of what is being displayed in a browser window based on the javascripts' window object properties (http://www.javascriptkit.com/jsref/window.shtml) to which I have access. I just can't seem to find the right mathematical formula for the zoom based on the inner width, page offset, etc. I found a solution, but that uses the document.body.getBoundingClientRect call which does not return anything in my case and for which I can't tell if there's a suitable replacement from the window properties. I am using Safari. Thank you, Mihai

  • OutOfMemoryException Processing Large File

    - by Krip
    We are loading a large flat file into BizTalk Server 2006 (Original release, not R2) - about 125 MB. We run a map against it and then take each row and make a call out to a stored procedure. We receive the OutOfMemoryException during orchestration processing, the Windows Service restarts, uses full 2 GB memory, and crashes again. The server is 32-bit and set to use the /3GB switch. Also I've separated the flow into 3 hosts - one for receive, the other for orchestration, and the third for sends. Anyone have any suggestions for getting this file to process wihout error? Thanks, Krip

  • load/unload C dll with C# problems

    - by Goran
    I'm having problems with external native DLL. I'm working on ASP.NET 1.1 web application and have this DLL which I load through DLLImport directives. This is how I map DLL functions: [DllImport("somedllname", CallingConvention=CallingConvention.StdCall)] public static extern int function1(string lpFileName,string lpOwnerPw,string lpUserPw); [DllImport("somedllname", CallingConvention=CallingConvention.StdCall)] public static extern int function2(int nHandle); I call the dll methods and all works great, but I have problems with this DLL crashing my web site on some cases, so I would like an option to unload the dll after I use it. I found a solution at this link, but I don't have 'UnmanagedFunctionPointer' attribute in .NET 1.1 available. http://blogs.msdn.com/jonathanswift/archive/2006/10/03/Dynamically-calling-an-unmanaged-dll-from-.NET-_2800_C_23002900_.aspx Is there a way I can achieve what this guy did with his example?

  • Dealing with unwanted port numbers on localhost when debugging in Visual Studio

    - by Dan Bailiff
    So when I'm trying to debug a project in Visual Studio, I'll often have 1 or more services that I need to call. These services are separate projects and I'll launch them in separate instances of VS. ASP dev server kindly launches them with temporary port numbers attached. This would be fine except for my programs are looking for an IP without a port attached. (Typically it's as simple as "localhost"!) I've coped by using web config settings and changing the xml to use the port number while debugging. This still doesn't always work and occasionally I'll still have to fudge it and insert port numbers as strings in code! UGH! Then I have to remember to undo all the port herding code before deployment... I want to stop doing this: string _strBaseURL = String.Format("http://{0}:2277", ConfigurationManager.AppSettings["myservice_ip"].ToString()); What is the best practice here? Am I doomed to port herding while debugging VS apps?

  • Automate gdb: show backtrace every 10 ms.

    - by osgx
    Hello I want to write a script for gdb, which will save backtrace (stack) of process every 10 ms. How can I do this? It can be smth like call graph profiling for 'penniless' (for people, who can't use any sort of advanced profiler). Yes, there are a lot of advanced profilers. For popular CPUs and for popular OSes. Shark is very impressive and easy to use, but I want to get a basic functionality with such script, working with gdb.

  • Is there a way to circumvent Python list.append() becoming progressively slower in a loop as the lis

    - by Deniz
    I have a big file I'm reading from, and convert every few lines to an instance of an Object. Since I'm looping through the file, I stash the instance to a list using list.append(instance), and then continue looping. This is a file that's around ~100MB so it isn't too large, but as the list grows larger, the looping slows down progressively. (I print the time for each lap in the loop). This is not intrinsic to the loop ~ when I print every new instance as I loop through the file, the program progresses at constant speed ~ it is only when I append them to a list it gets slow. My friend suggested disabling garbage collection before the while loop and enabling it afterward & making a garbage collection call. Did anyone else observe a similar problem with list.append getting slower? Is there any other way to circumvent this?
