• Strange MSI error when setup.exe is run

  - by Martin Jackson

  We're using Visual Studio 2008's Setup Project to create an installer for our .NET 3.5 app. We host the .exe and .msi files on a website for our client to access, and produce new ones regularly to provide updates. This has all been fine until recently we've noticed some cases where installing via the .exe fails. The symptoms are: The .exe downloads fine, and runs fine. It appears to download the .msi successfully (the "downloading application files" step plods through happily), but then when it gets to the end of the "preparing to install" step, instead of launching the installer UI it pops up a message saying "This installation package could not be opened. Verify that the package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer package". You'd think that the .msi is just corrupt or something, but running it explicitly (even downloading it from the same location as the .exe to do so) works just fine. This problem is occurring on just some of our machines, which are running a mixture of XP and Windows7. The only pattern I can see in those machines that experience the problem is that they tend to have had the application installed on them longer (i.e. updating the app rather than installing for the first time). It seems to me that it might be something to do with how/where the .exe downloads the .msi to, and perhaps different versions are conflicting there? Has anyone experienced this before? Does anyone know where the installer .exe puts the .msi that it downloads?

• Which Java Framework is best suited for a web application with reusable content/behavior

  - by Jacob

  I come from a .NET background and need to do a web project in Java. I have read a bit on all the different Java web frameworks out there: JSF, Stripes, Wicket, Tapestry etc. But I would like to hear from people with real-life expertise with these frameworks. Of course I want a framework that is up to date, supports AJAX, is cool and so on, but one of my main criteria is the ability to somehow create reusable components / tags. The customer needs to be able to move tags/components around without too much problem in order to customize it for their specific needs. In ASP.NET Webforms I would use custom controls and user controls for this, and in ASP.NET MVC I would use user controls as well as home made custom controls. So what Java frameworks excel in this? My own superficial research seems to conclude that JSF supports some kind of custom controls (Bear in mind i am not only talking about layout reuse, but also behavior reuse, so if for example the customer / client wants a customer list on page x and not only on page Y, he would simply put in a <jr:CustomerList runat="server" .... /> (fictional example with ASP.NET Webforms syntax)).

• Kerberos and/or other authentication systems - One time logon for all PHP scripts

  - by devviedev

  I'm managing a set of web apps, almost exclusively written in PHP, and would like to find an authentication platform to build a role-based authorization system on top of. Also, I'd like the authentication system to be extensible to use for, for example, system services (SSH, etc.) Here are some of the main characteristics I'm looking for, in order of importance: Easy PHP implementation (storing/reading easily roles, etc.). Redundant, if possible. If an auth system goes down everyone is not locked out. Has clients for Windows and Mac. Easy web-based administration (adding/removing users/roles, changing passwords). If not, I can build an administration system without too much effort. One-time log on. I'd also like, when an auth token is issued, to store the user's IP address and use that to authorize the user for some non web-based applications. For that reason, I'd like a desktop client to issue the token and revoke tokens when, for example, the user becomes idle at their workstation. I'm thinking Kerberos might be a solution, but what are other options?

• Users in database server or database tables

  - by Batcat

  Hi all, I came across an interesting issue about client server application design. We have this browser based management application where it has many users using the system. So obvisously within that application we have an user management module within it. I have always thought having an user table in the database to keep all the login details was good enough. However, a senior developer said user management should be done in the database server layer if not then is poorly designed. What he meant was, if a user wants to use the application then a user should be created in the user table AND in the database server as a user account as well. So if I have 50 users using my applications, then I should have 50 database server user logins. I personally think having just one user account in the database server for this database was enough. Just grant this user with the allowed privileges to operate all the necessary operation need by the application. The users that are interacting with the application should have their user accounts created and managed within the database table as they are more related to the application layer. I don't see and agree there is need to create a database server user account for every user created for the application in the user table. A single database server user should be enough to handle all the query sent by the application. Really hope to hear some suggestions / opinions and whether I'm missing something? performance or security issues? Thank you very much.

• yet another question about migrating to Java

  - by aloneguid

  Hi, There are plenty similar questions, but maybe responses to this one will save a developer's life :) I want to migrate to Java. The reasons are very clear: all the .NET vacancies are client and windows oriented (Silverlight developer, ASP.NET developer, WPF developer etc.) and none of them are any interest to me. I worked with .NET since it's beginning as our company decided to invest in .NET having C++ stack and all the natual problems, so I was just blindly following and actually enjoyed it as the products were mostly server oriented with mixed C++/C# code. Today I have beforementioned problem - can't find an inspiring job. I'd rather kill myself than start working on a Silverlight or WPF project. Searching Java vacancies shows promising results, however they all require a huge java-related technology stack and experience. The question is is there any chance to find a job quickly and without dramatic salary drop (I know that Java guys are usually better paid, so there must be a kind of a credit) and if not, how must time and effort does it take to migrate (my .NET knowledge mostly includes server-oriented technologies like NHibernate, WCF, threading, sockets, ASP.NET web services, Enterprise Library, NInject etc etc etc, and (still) some C++ leftovers). Thanks!

• Version Control and Coding Formatting

  - by Martin Giffy D'Souza

  Hi, I'm currently part of the team implementing a new version control system (Subversion) within my organization. There's been a bit of a debate on how to handle code formatting and I'd like to get other peoples opinions and experiences on this topic. We currently have ~10 developers each using different tools (due to licensing and preference). Some of these tools have automatic code formatters and others don't. If we allow "blind" checkins the code will look drastically different each time someone does a check in. This will make things such as diffs and merges complicated. I've talked to several people and they've mentioned the following solutions: Use the same developer program with the same code formatter (not really an option due to licensing) Have a hook (either client or server side) which will automatically format the code before going into the repository Manually format the code. Regarding the 3rd point, the concept is to never auto-format the code and have some standards. Right now that seems to be what we're leaning towards. I'm a bit hesitant on that approach as it could lead to developers spending a lot of time manually formatting code. If anyone can please provide some their thoughts and experience on this that would be great. Thank you, Martin

• How do you handle your "Project Manager"

  - by Vecdid

  I currently work for a company who recently has downsized. I do all in house work, client installs, builds,q.a, well basically all the in house work. My direct boss is VERY untechnical and lately I have found it VERY hard to deal with his lack of knowledge. The biggest issues I have had are as follows: I am on many deadlines at a time. I get stopped to put together a half fast quote as I cannot be late on the deadline, in the meantime, three support calls comes in, I give quote, time too much so they outsource it. I then I have to fix everything the vendor broke. I get asked, when an issue arrises, why is the issue occurring and explain in detail, yet that detail means absolutly nothing to him. All he cares about are deadlines, yet he is the one who schdules everything. "I am a programmer not a graphic designer, meaqns nothing to him" I was hired as a .NET programmer, yet they let a vendor choose wordpress for many sites(yeah I had to learn all about it quick) I guess I can go on and on, but has anyone had to deal with this type of project manager? What is some advice, other than finding another job. Thanks in advance, and I made this a wiki, so please don't close...

• Deploying .NET COM dll, getting error (0x80070002)

  - by Brett

  I have a .NET COM assembly I am attempting to deploy to a web server (IIS 6 Win 2003). We have successfully deployed this assembly to our test environment, but the production environment is not working. The assembly is being called from a classic ASP page. Every time that page tries to initialize the assembly with “Set LTMRender = CreateObject("LTMRender.Render")”, I get an error “Error Type:, (0x80070002)”. This error seems to indicate a permission denied, or file not found type problem. I created a test app to see if the assembly works outside of the web page. The .exe initializes the assembly, and then makes a call designed to fail which in turn causes the assembly to produce a log file. It works if I run the .exe in the same folder as the assembly, but fails if I run it elsewhere. For some reason, the assembly is not accessible from outside it’s folder. I can’t figure out why this won’t work. Things I have confirmed: The deployment folder has adequate permissions. We have confirmed that the folder the assembly in installed in has the correct permissions for all the necessary user accounts. The Assembly is signed with a strong name, and was registered with regasm.exe C:_WebSites\LTMRender\LTMRender.dll /codebase /tlb:C:_WebSites\LTMRender\LTMRender.tlb. Regasm reported success. The Assembly has the attribute and relevant GUID’s set correctly. Any tips? EDIT We ran filemon against my testapp.exe and it seems to have indicated what the problem is. When testapp.exe runs in D:_websites\DocWebV2\ or D:_websites\DocWebV2\ LTMRender\ folder, it succeeds and filemon is showing D:_websites\DocWebV2\LTMRender\pinPDF.dll SUCCESS If I run my testapp.exe in the D:_websites\DocWebV2\Client – where my asp pages run, it shows D:_websites\DocWebV2\pinPDF.dll NAME NOT FOUND and then D:_websites\DocWebV2\pinPDF\pinPDF.dll FILE NOT FOUND I’m not sure why it is not looking in the correct folder if it’s under this particular folder only.

• setInterval alternative

  - by spyder

  Hi folks, In my app I am polling the webserver for messages every second and displaying them in the frontend. I use setInterval to achieve this. However as long as the user stays on that page the client keeps polling the server with requests even if there is no data. The server does give an indication when no more messages are being generated by setting a variable. I thought of using this variable to clearInterval and stop the timer but that didn't work. What else can I use in this situation? I am using jquery and django. Here is my code: jquery: var refresh = setInterval( function () { var toLoad = '/myMonitor'+' #content'; $('#content').load(toLoad).show(); }, 1000); // refresh every 1000 milliseconds }); html: div id=content is here I can access the django variable for completion in html with each refresh. How can I set clearInterval if at all ? Note: stack overflow does not let me put is &gt &lt so html is incomplete Thanks

• How can I track down "Template process failed: undef error" in Perl's Template Toolkit?

  - by swisstony

  I've moved a Perl CGI app from one web host to another. Everything's running fine except for Template Tookit which is giving the following error: "Template process failed: undef error - This shouldn't happen at /usr/lib/perl5/5.8.8/CGI/Carp.pm line 314." The templates are working fine on the other web host. I've set the DEBUG_ALL flag when creating the template object, but it doesn't provide any additional info about errors just loads of debug output. I can't post the template source as there's lots of client specific stuff in it. I've written a simple test template and that works okay. Just wondering if anyone had seen this error before or has any ideas on the quickest way to find a fix for it. EDIT: Here's a snippet of the code that loads and processes the template. my $vars = {}; $vars->{page_url} = $page_url; $vars->{info} = $info; $vars->{is_valid} = 0; $vars->{invalid_input} = 0; $vars->{is_warnings} = 0; $vars->{is_invalid_price} = 0; $vars->{output_from_proc} = $proc_output; ... my $file = 'clientTemplate.html'; #create ref to hash use Template::Constants qw( :debug ); my $template = Template->new( { DEBUG => DEBUG_SERVICE | DEBUG_CONTEXT | DEBUG_PROVIDER | DEBUG_PLUGINS | DEBUG_FILTERS | DEBUG_PARSER | DEBUG_DIRS, EVAL_PERL => 1, INCLUDE_PATH => [ '/home/perlstuff/templates', ], } ); $template->process( $file, $vars ) || die "Template process failed: ", $template->error(), "\n";

• Mixed Mode C++ DLL function call failure when app launched from network share. Called from unmanage

  - by Steve

  Mixed-mode DLL called from native C application fails to load: An unhandled exception of type 'System.IO.FileLoadException' occurred in Unknown Module. Additional information: Could not load file or assembly 'XXSharePoint, Version=0.0.0.0, Culture=neutral, PublicKeyToken=e0fbc95fd73fff47' or one of its dependencies. Failed to grant minimum permission requests. (Exception from HRESULT: 0x80131417) My environment is: Native C application calling a mixed mode C++ DLL, which then loads a C# DLL.. This works correctly when loaded from a local drive, but when launched from a network drive, it fails with the above messages. The call to LoadLibrary succeeds, as does the GetProcAddress. The load error happens when I call the function. I have digitally signed the C application, and I've performed "strong name" signing on the 2 DLLs. The PublickKeyToken in the message above does match the named DLL. I have also issued the CASPOLcommands on my client to grant FullTrust to that strong name keytoken. When that failed to work, I tried the CASPOL command to grant FullTrust to the URL of the network drive (including path to my application's directory); no change in results. I tried removing all dependencies, so that there was just the initial mixed-mode DLL... I replaced the bodies of all the functions with just a return of a "success" integer value. Results unchanged. Only when I changed it from Mixed Mode to Win32, and changed the Configuration Properties General Common Language Runtime Support from "Common Language Runtime Support" to "No Common Language Runtime Support" did calling the DLL produce the expected result (just returned the "success" integer return value).

• Which PHP library I should choose to work with CouchDB?

  - by Guss

  I want to try playing with CouchDB for a new project I'm writing (as a hobby, not part of my job). I'm well versed in PHP, but I haven't programmed with CouchDB at all, and also I have little experience with non-SQL databases. From looking at CouchDB's "Getting Started with PHP" document they recommend using a third-party library or writing your own client using their RESTful HTTP API. I think I'd rather not mess with writing protocol implementations myself at this point, but what is your experience with writing PHP to work with CouchDB? I haven't tested any of the alternatives yet, but I looked at: PHPillow : I'm interested in the way they implement ORM. I wasn't planning to do ORM, but my problem domain probably map well to that method. PHP Object Freezer: seems like a poor man's ORM - I can use it to implement an actual ORM, or just as an easy store/retrieve document API but it seems too primitive. PHP-on-Couch : Also a bit simple, but they have an interesting API for views and from the documentation it looks usable enough. PHP CouchDB Extension : From the listed options this looks like it has the best chance of making it into the PHP mainline itself, and also has the most complete API. Any opinion one wish to share on each library is welcome.

• Access Expression problem: it's too complex, so how do I turn it in to a function?

  - by Mike

  Access 2007 is telling me that my new expression is to complex. It used to work when we had 10 service levels, but now we have 19! Great! I've asked this question in SuperUser and someone suggested I try it over here. Suggestions are I turn it in to a function - but I'm not sure where to begin and what the function would look like. My expression is checking the COST of our services in the [PriceCharged] field and then assigning the appropriate HOURS [Servicelevel] when I perform a calculation to work out how much REVENUE each colleague has made when working for a client. The [EstimatedTime] field stores the actual hours each colleague has worked. [EstimatedTime]/[ServiceLevel]*[PriceCharged] Below is the breakdown of my COST to HOURS expression. I've put them on different lines to make it easier to read - please do not be put off by the length of this post, it's all the same info in the end. Many thanks,Mike ServiceLevel: IIf([pricecharged]=100(COST),6(HOURS), IIf([pricecharged]=200 Or [pricecharged]=210,12.5, IIf([pricecharged]=300,19, IIf([pricecharged]=400 Or [pricecharged]=410,25, IIf([pricecharged]=500,31, IIf([pricecharged]=600,37.5, IIf([pricecharged]=700,43, IIf([pricecharged]=800 Or [pricecharged]=810,50, IIf([pricecharged]=900,56, IIf([pricecharged]=1000,62.5, IIf([pricecharged]=1100,69, IIf([pricecharged]=1200 Or [pricecharged]=1210,75, IIf([pricecharged]=1300 Or [pricecharged]=1310,100, IIf([pricecharged]=1400,125, IIf([pricecharged]=1500,150, IIf([pricecharged]=1600,175, IIf([pricecharged]=1700,200, IIf([pricecharged]=1800,225, IIf([pricecharged]=1900,250,0)))))))))))))))))))

• Mimic remote API or extend existing django model

  - by drozzy

  I am in a process of designing a client for a REST-ful web-service. What is the best way to go about representing the remote resource locally in my django application? For example if the API exposes resources such as: List of Cars Car Detail Car Search Dealership summary So far I have thought of two different approaches to take: Try to wrangle the django's models.Model to mimic the native feel of it. So I could try to get some class called Car to have methods like Car.objects.all() and such. This kind of breaks down on Car Search resources. Implement a Data Access Layer class, with custom methods like: Car.get_all() Car.get(id) CarSearch.search("blah") So I will be creating some custom looking classes. Has anyone encoutered a similar problem? Perhaps working with some external API's (i.e. twitter?) Any advice is welcome. PS: Please let me know if some part of question is confusing, as I had trouble putting it in precise terms.

• Execute code on assembly load

  - by Dmitriy Matveev

  I'm working on wrapper for some huge unmanaged library. Almost every of it's functions can call some error handler deeply inside. The default error handler writes error to console and calls abort() function. This behavior is undesirable for managed library, so I want to replace the default error handler with my own which will just throw some exception and let program continue normal execution after handling of this exception. The error handler must be changed before any of the wrapped functions will be called. The wrapper library is written in managed c++ with static linkage to wrapped library, so nothing like "a type with hundreds of dll imports" is present. I also can't find a single type which is used by everything inside wrapper library. So I can't solve that problem by defining static constructor in one single type which will execute code I need. I currently see two ways of solving that problem: Define some static method like Library.Initialize() which must be called one time by client before his code will use any part of the wrapper library. Find the most minimal subset of types which is used by every top-level function (I think the size of this subset will be something like 25-50 types) and add static constructors calling Library.Initialize (which will be internal in that scenario) to every of these types. I've read this and this questions, but they didn't helped me. Is there any proper ways of solving that problem? Maybe some nice hacks available?

• Does Team Foundation support cross-app workitem groups?

  - by drachenstern

  We're currently using Visual Source Safe and BugNet and looking to migrate up and away from VSS. I've been pushing for either SVN ( a) we're an ASP.NET shop, b) DCVS is not an option - no matter how much I like Hg ;-) or TFS. Well we finally got a new dev server, so I talked the boss into installing TFS on it (30 day trial). In the meantime, we had started experimenting with FogBugz. We really like FogBugz for about 80% of what we want to do, and the other 20% is probably stuff that we don't know what we want. I'm pushing for TFS because it allows for IDE integrated (mostly) everything. He's pushing for FogBugz because he can group tasks by customer and then project and manage everything from one dashboard. (which means I lose most of my IDE integration - no huge loss I agree) Does TFS support a single dashboard that would span all our solutions (in this case each solution is a full app that we sell to a vertical market client) and let us assign workitems to each solution-spanning-group? So for instance I think we envision something like this: PROJECT1 - Bugtracker and workitems PROJECT2 - Bugtracker and workitems PROJECT3 - Bugtracker and workitems CUSTOMER1 - Deployment schedules, required features, specific notes (Uses PROJECT1, PROJECT2) CUSTOMER2 - Deployment schedules, required features, specific notes (Uses PROJECT2, PROJECT3) CUSTOMER3 - Deployment schedules, required features, specific notes (Uses PROJECT1, PROJECT3) Hopefully that makes sense. naturally it's more complicated than this but I think I've given the details enough to paint a picture. I offered the option of creating dummy projects per customer but he doesn't like that and it doesn't really give us the single dashboard view that we're hoping to end up with (and that FogBugz as we've sorta implmented things does do now). Has anyone got a good suggestion on a management app that would accomplish what both of us want?

• How to get HTTP status code in HTTPService fault handler

  - by Ankur

  I am calling a server method through HTTPService from client side. The server is a RestFul web service and it might respond with one of many HTTP error codes (say, 400 for one error, 404 for another and 409 for yet another). I have been trying to find out the way to determine what was the exact error code sent by the server. I have walked teh entire object tree for the FaultEvent populated in my fault handler, but no where does it tell me the error code. Is this missing functionality in Flex? My code looks like this: The HTTP Service declaration: <mx:HTTPService id="myServerCall" url="myService" method="GET" resultFormat="e4x" result="myServerCallCallBack(event)" fault="faultHandler(event)"> <mx:request> <action>myServerCall</action> <docId>{m_sDocId}</docId> </mx:request> </mx:HTTPService> My fault handler code is like so: private function faultHandler(event : FaultEvent):void { Alert.show(event.statusCode.toString() + " / " + event.fault.message.toString()); }

• Using multiple sockets, is non-blocking or blocking with select better?

  - by JPhi1618

  Lets say I have a server program that can accept connections from 10 (or more) different clients. The clients send data at random which is received by the server, but it is certain that at least one client will be sending data every update. The server cannot wait for information to arrive because it has other processing to do. Aside from using asynchronous sockets, I see two options: Make all sockets non-blocking. In a loop, call recv on each socket and allow it to fail with WSAEWOULDBLOCK if there is no data available and if I happen to get some data, then keep it. Leave the sockets as blocking. Add all sockets to a fd_set and call select(). If the return value is non-zero (which it will be most of the time), loop through all the sockets to find the appropriate number of readable sockets with FD_ISSET() and only call recv on the readable sockets. The first option will create a lot more calls to the recv function. The second method is a bigger pain from a programming perspective because of all the FD_SET and FD_ISSET looping. Which method (or another method) is preferred? Is avoiding the overhead on letting recv fail on a non-blocking socket worth the hassle of calling select()? I think I understand both methods and I have tried both with success, but I don't know if one way is considered better or optimal. Only knowledgeable replies please!

• img onload doesn't work well in IE7

  - by rmeador

  I have an img tag in my webapp that uses the onload handler to resize the image: <img onLoad="SizeImage(this);" src="foo" > This works fine in Firefox 3, but fails in IE7 because the image object being passed to the SizeImage() function has a width and height of 0 for some reason -- maybe IE calls the function before it finishes loading?. In researching this, I have discovered that other people have had this same problem with IE. I have also discovered that this isn't valid HTML 4. This is our doctype, so I don't know if it's valid or not: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> Is there a reasonable solution for resizing an image as it is loaded, preferably one that is standards-compliant? The image is being used for the user to upload a photo of themselves, which can be nearly any size, and we want to display it at a maximum of 150x150. If your solution is to resize the image server-side on upload, I know that is the correct solution, but I am forbidden from implementing it :( It must be done client side, and it must be done on display. Thanks. Edit: Due to the structure of our app, it is impractical (bordering on impossible) to run this script in the document's onload. I can only reasonably edit the image tag and the code near it (for instance I could add a <script> right below it). Also, we already have Prototype and EXT JS libraries... management would prefer to not have to add another (some answers have suggested jQuery). If this can be solved using those frameworks, that would be great. Edit 2: Unfortunately, we must support Firefox 3, IE 6 and IE 7. It is desirable to support all Webkit-based browsers as well, but as our site doesn't currently support them, we can tolerate solutions that only work in the Big 3.

• Actionscript image download open custom viewer

  - by Vish

  Hi Gurus, i am downloading tiff images from WAMP server using our Flex AIR client. Using the following code for that. public static function requestDownload(id:int, defaultName:String):void { //POST params var urlVars:URLVariables = new URLVariables(); urlVars.action = "download"; urlVars.fid = id; var urlReq:URLRequest = new URLRequest(); urlReq.url = Config.getServerURL(); urlReq.data = urlVars; Config.fileReference.addEventListener(Event.,FileDownload.requestDownloadResultV); try { Config.fileReference.download(urlReq, defaultName); } catch (e:Error) { Alert.show("Error in downloading the file"); } } public static function requestDownloadResultV(e:Event):void { Alert.show("File downloaded"); } No issues with the download. It automatically prompts for a Save dialog. Works well. But i want to open the image being downloaded in a viewer(flash viewer or any) instead of the save dialog. Please help me. Thanks Vish.

• Is this correct for disposing an object using IDisposable

  - by robUK

  I have a class that implements the IDisposable interface. I am using a webclient to download some data using the AsyncDownloadString. I am wondering have I correctly declared my event handlers in the constructor and within the using statement of the web client? And is this correct way to remove the event handlers in the Dispose method? Overrule is this the correct way to use the IDisposable interface? public class Balance : IDisposable { //Constructor WebClient wc; public Balance() { using (wc = new WebClient()) { //Create event handler for the progress changed and download completed events wc.DownloadProgressChanged += new DownloadProgressChangedEventHandler(wc_DownloadProgressChanged); wc.DownloadStringCompleted += new DownloadStringCompletedEventHandler(wc_DownloadStringCompleted); } } ~Balance() { this.Dispose(false); } //Get the current balance for the user that is logged in. //If the balance returned from the server is NULL display error to the user. //Null could occur if the DB has been stopped or the server is down. public void GetBalance(string sipUsername) { //Remove the underscore ( _ ) from the username, as this is not needed to get the balance. sipUsername = sipUsername.Remove(0, 1); string strURL = string.Format("https://www.xxxxxxx.com", sipUsername); //Download only when the webclient is not busy. if (!wc.IsBusy) { // Download the current balance. wc.DownloadStringAsync(new Uri(strURL)); } else { Console.Write("Busy please try again"); } } //return and display the balance after the download has fully completed void wc_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) { //Pass the result to the event handler } //Dispose of the balance object public void Dispose() { Dispose(true); GC.SuppressFinalize(this); } //Remove the event handlers private bool isDisposed = false; private void Dispose(bool disposing) { if (!this.isDisposed) { if (disposing) { wc.DownloadProgressChanged -= new DownloadProgressChangedEventHandler(wc_DownloadProgressChanged); wc.DownloadStringCompleted -= new DownloadStringCompletedEventHandler(wc_DownloadStringCompleted); wc.Dispose(); } isDisposed = true; } } }

• Integrating Magento with SAP ECC 6.0 Backend

  - by ikarous

  I'm a freshly graduated (read: inexperienced) developer who's been tasked with determining the feasibility of integrating Magento with an SAP-based backend. No developer at our company has any experience working with either SAP or Magento, so I was hoping that the Stack Overflow community may be able to point me in the right direction with my research. We're a small company (four full-time developers) and the timeline on this project would be tight, so I'm trying to gather as much information as possible. The client has a tiered pricing structure, tax calculation logic, promotional deals, and automatic freight determination all implemented in an SAP ECC 6.0 system. They would like to migrate all their online stores over to Magento while continuing to utilize all existing functionality in SAP. The idea is to accomplish this by overriding certain modules in Magento to place remote calls to SAP BAPIs. I've investigated SAPRFC, which looks promising but relatively stale in terms of update frequency. Do any developers have experience using SAPRFC with SAP ECC 6.0 (with or without Magento integration)? If so, what were your experiences, and what were the biggest risk factors involved? Any comments, suggestions, or links to resources would be greatly appreciated.

• simple Java "service provider frameworks"?

  - by Jason S

  I refer to "service provider framework" as discussed in Chapter 2 of Effective Java, which seems like exactly the right way to handle a problem I am having, where I need to instantiate one of several classes at runtime, based on a String to select which service, and an Configuration object (essentially an XML snippet): But how do I get the individual service providers (e.g. a bunch of default providers + some custom providers) to register themselves? interface FooAlgorithm { /* methods particular to this class of algorithms */ } interface FooAlgorithmProvider { public FooAlgorithm getAlgorithm(Configuration c); } class FooAlgorithmRegistry { private FooAlgorithmRegistry() {} static private final Map<String, FooAlgorithmProvider> directory = new HashMap<String, FooAlgorithmProvider>(); static public FooAlgorithmProvider getProvider(String name) { return directory.get(serviceName); } static public boolean registerProvider(String name, FooAlgorithmProvider provider) { if (directory.containsKey(name)) return false; directory.put(name, provider); return true; } } e.g. if I write custom classes MyFooAlgorithm and MyFooAlgorithmProvider to implement FooAlgorithm, and I distribute them in a jar, is there any way to get registerProvider to be called automatically, or will my client programs that use the algorithm have to explicitly call FooAlgorithmRegistry.registerProvider() for each class they want to use?

• How to make Facebook Authentication from Silverlight secure?

  - by SondreB

  I have the following scenario I want to complete: Website running some HTTP(S) services that returns data for a user. Same website is additionally hosting a Silverlight 4 app which calls these services. The Silverlight app is integrating with Facebook using the Facebook Developer Toolkit (http://facebooktoolkit.codeplex.com/). I have not fully decided whether I want Facebook-integration to be a "opt-in" option such as Spotify, or if I want to "lock" down my service with Facebook-only authentication. That's another discussion. How do I protect my API Key and Secret that I receive from Facebook in a Silverlight app? To me it's obvious that this is impossible as the code is running on the client, but is there a way I can make it harder or should I just live with the fact that third parties could potentially "act" as my own app? Using the Facebook Developer Toolkit, there is a following C# method in Silverlight that is executed from the JavaScript when the user has fully authenticated with Facebook using the Facebook Connect APIs. [ScriptableMember] public void LoggedIn(string sessionKey, string secret, int expires, long userId) { this.SessionKey = sessionKey; this.UserId = userId; Obvious the problem here is the fact that JavaScript is injection the userId, which is nothing but a simple number. This means anyone could potentially inject a different userId in JavaScript and have my app think it's someone else. This means someone could hijack the data within the services running on my website. The alternative that comes to mind is authenticating the users on my website, this way I'm never exposing any secrets and I can return an auth-cookie to the users after the initial authentication. Though this scenario doesn't work very well in an out-of-browser scenario where the user is running the Silverlight app locally and not from my website.
