• Dynamic Collapsable Flow Chart Online

  - by Simon

  Been looking through a number of other related posts relating to flowchart software. I have been asked to put together a document outlining some of the typical problems our users encounter with our software product. What I would like to do, is create an interactive/online flowchart that lets users choose from 4-5 overall headings on whats wrong. Then for this to dynamically expand more choices on pinpointing the problem, and so on and so on, until they can get a resolution to their problem. The key thing that I have not been able to find in some of the flowchart software out there, is having the click + expand element. - I dont want all options to appear to the end-user in a huge flow chart as it will distract away from their specific issue. - I want them to be able to click away and go down a specific avenue that will end up giving them some good things to try, based on their decisions/clicks. I was originally thinking of perhaps putting something in Flex or Silverlight (ideally someone would have a template out there) but am now thinking of taking advantage of 3rd party (ideally free) software. This will need to be hosted in a browser. Any ideas?

• File descriptor limits and default stack sizes

  - by Charles

  Where I work we build and distribute a library and a couple complex programs built on that library. All code is written in C and is available on most 'standard' systems like Windows, Linux, Aix, Solaris, Darwin. I started in the QA department and while running tests recently I have been reminded several times that I need to remember to set the file descriptor limits and default stack sizes higher or bad things will happen. This is particularly the case with Solaris and now Darwin. Now this is very strange to me because I am a believer in 0 required environment fiddling to make a product work. So I am wondering if there are times where this sort of requirement is a necessary evil, or if we are doing something wrong. Edit: Great comments that describe the problem and a little background. However I do not believe I worded the question well enough. Currently, we require customers, and hence, us the testers, to set these limits before running our code. We do not do this programatically. And this is not a situation where they MIGHT run out, under normal load our programs WILL run out and seg fault. So rewording the question, is requiring the customer to change these ulimit values to run our software to be expected on some platforms, ie, Solaris, Aix, or are we as a company making it to difficult for these users to get going? Bounty: I added a bounty to hopefully get a little more information on what other companies are doing to manage these limits. Can you set these pragmatically? Should we? Should our programs even be hitting these limits or could this be a sign that things might be a bit messy under the covers? That is really what I want to know, as a perfectionist a seemingly dirty program really bugs me.

• AnyCPU/x86/x64 for C# application and it's C++/CLI dependency

  - by Soonts

  I'm Windows developer, I'm using Microsoft visual studio 2008 SP1. My developer machine is 64 bit. The software I'm currently working on is managed .exe written in C#. Unfortunately, I was unable to solve the whole problem solely in C#. That's why I also developed a small managed DLL in C++/CLI. Both projects are in the same solution. My C# .exe build target is "Any CPU". When my C++ DLL build target is "x86", the DLL is not loaded. As far as I understood when I googled, the reason is C++/CLI language, unlike other .NET languages, compiles to the native code, not managed code. I switched the C++ DLL build target to x64, and everything works now. However, AFAIK everything will stop working as soon as my client will install my product on a 32-bit OS. I have to support Windows Vista and 7, both 32 and 64 bit versions of each of them. I don't want to fall back to 32 bits. That 250 lines of C++ code in my DLL is only 2% of my codebase. And that DLL is only used in several places, so in the typical usage scenario it's not even loaded. My DLL implements two COM objects with ATL, so I can't use "/clr:safe" project setting. Is there way to configure the solution and the projects so that C# project builds "Any CPU" version, the C++ project builds both 32 bit and 64 bit versions, then in the runtime when the managed .EXE is starting up, it uses either 32-bit DLL or 64-bit DLL depending on the OS? Or maybe there's some better solution I'm not aware of? Thanks in advance!

• Manifesto for Integrated Development Environments

  - by Hugo S Ferreira

  Have you recently take a peek at Coda, or Espresso, or Textmate? Or even Google Chrome's Developer Tools? They are well designed, intuitive, interface rich, and extensible. But Coda, Espresso or Textmate, among several, are text editors, not IDEs. On the other side, VIM and Emacs live in the last century, and Eclipse is an overbloated platform. This is more like an outcry for a decent, common infrastructure for REAL IDEs. But there's some questions attached: (i) what features are needed for such a product and (ii) what products are out there that could fullfil this need, and what are they missing. So here's my draft for a manifesto: Manifesto for Integrated Development Environments: We favor interactivity and productivity over syntax and tools. We favor inline, contextual documentation over man and html files. We favor high-definition, graphic-capable color screens over 80x25 character terminals. We favor the use of advanced input schemas over unintuitive keyboard shortcuts. We favor a common, extensible and customizable infrastructure over unmaintained chaintools. We know the difference between search&replace and refactoring. We know the difference between integrated debugging support over a terminal window. We know the difference between semantic-aware code-completion over dumb textual templates. We favor the usage of standards like (E)BNF.

• Significance in R

  - by Gemsie

  Ok, this is quite hard to explain, but I'm at a complete loss what to do. I'm a relative newcomer to R and although I can completely admire how powerful it is, I'm not too good at actually using it.... Basically, I have some very contrived data that I need to analyse (it wasn't me who chose this, I can assure you!). I have the right and left hand lengths of lots of people, as well as some numeric data that shows their sociability. Now I would like to know if people who have significantly different lengths of hand are more or less sociable than those who have the same (leading into the research that 'symmetrical' people are more sociable and intelligent, etc. I have got as far as loading the data into R, then I have no idea where to go from there. How on Earth do I start to separate those who are close to symmetrical to those who aren't to then start to do the analysis? Ok, using Sasha's great advice, I did the cor.test and got the following: Pearson's product-moment correlation data: measurements$l.hand - measurements$r.hand and measurements$sociable t = 0.2148, df = 150, p-value = 0.8302 alternative hypothesis: true correlation is not equal to 0 95 percent confidence interval: -0.1420623 0.1762437 sample estimates: cor 0.01753501 I have never used this test before, so am unsure how to intepret it...you wouldn't think I was on my fourth Scientific degree would you?! :(

• Opening my application when a usb device is inserted on Windows using WMI

  - by rsteckly

  Hi, I'm trying to launch an event when someone plugs in a usb device. For now, I'm content to simply print something to the console (in the finished product, it will launch an application). This code is very loosely adapted from: http://serverfault.com/questions/115496/use-wmi-to-detect-a-usb-drive-was-connected-regardless-of-whether-it-was-mounted There's two problems: 1) I need to pass the argument to Management scope dynamically because this will be installed on computers I don't use or whose name I don't know. 2) I'm getting an invalid namespace exception when I call w.Start(); Any ideas what I'm doing wrong? static ManagementEventWatcher w=null; static void Main(string[] args) { AddInstUSBHandler(); for(;;); } public static void USBRemoved(object sneder, EventArgs e) { Console.WriteLine("A USB device inserted"); } static void AddInstUSBHandler() { WqlEventQuery q; ManagementScope scope = new ManagementScope("HQ\\DEV1"); scope.Options.EnablePrivileges=true; q=new WqlEventQuery(); q.EventClassName+="_InstanceCreationEvent"; q.WithinInterval=new TimeSpan(0,0,3); q.Condition=@"TargetInstance ISA 'Win32_USBControllerdevice'"; w=new ManagementEventWatcher(scope,q); w.EventArrived+=new EventArrivedEventHandler(USBRemoved); w.Start(); }

• Reservation Solution for RealEstate integrating with Joomla

  - by Pennf0lio

  Hi, My client needs a Property (Just Land NO Houses) Reservation solution for their existing website (It runs in Joomla). I need some advice/Tips on what approach should I use. I'm looking for an Opensource solution that I can customize to my need. The Scenario: A buyer reserves a lot, A form appears gathers his details after that he/she pays for the reservation. FrontEnd: I need a form builder extension in Joomla that I could build custom form in gathering information (name, email, contact info, address...) from the buyer or the person who is reserving it. After I gather the info I need another extension that will handle the payment for reserving it. This is kinda shopping cart type approach, you see a product and the buy it. But would just need extra details. Backend: I can see all the details of the buyer from their name to the time they paid for a reservation. Thanks! P.S. I'm open to all Ideas. I'm not sure of this approach. Please let me know If you have some good Ideas or example.

• Why does the answer print out twice?

  - by rEgonicS

  I made a program that returns the product a*b*c where a,b,c are pythagorean triples and add up to 1000. The program does output the correct answer but does it twice. I was curious as to why this is so.After playing around with it a bit I found out that it prints out when a = 200 b = 375 c = 425. And once again when a = 375 b = 200 c = 425. *How do you put your code into a "code" block? It does it automatically for part of the code but as you can see the top portion and bottom line is left out. bool isPythagTriple(int a, int b, int c); int main() { for(int a = 1; a < 1000; a++) { for(int b = 1; b < 1000; b++) { for(int c = 1; c < 1000; c++) { if( ((a+b+c)==1000) && isPythagTriple(a,b,c) ) { cout << a*b*c << " "; break; } } } } return 0; } bool isPythagTriple(int a, int b, int c) { if( (a*a)+(b*b)-(c*c) == 0 ) return true; else return false; }

• LDAP/AD Integrated Group/Membership Management Package suitable for embedding in an application

  - by Ernest

  In several web applications, it is often necessary to define groups of users for purposes of membership as well as role management. For example, in one of our applications we would like to user a group of "Network Engineers" and another group that consists of "Managers" of such Network Engineers. The information we need is contact details of members of each group. So far, we have written our own tools to allow the administrator of the application to add/delete/move groups and their memberships and either store them in a XML file or a database. Increasingly, companies already have the groups we want defined in LDAP/AD, so it would be best to create a pointer in our application to the correspoding group in LDAP. Although there are a number of LDAP libraries and LDAP browsers available and we could code this and provide a web front end to get a list of available groups and their members, we are wondering if there is already a "component framework" available that would readily provide this LDAP browsing functionality that we could just embed this into our application. Something between a library and a full LDAP browser product ? (To clarify, the use case is for an admin of our web application to create a locally relevant group name and then map it to an exiting LDAP group. To enable this in the UI, we would like to present a way for the admin to browse available groups in the company LDAP server, view their membership, and select the LDAP group they would like to map to the locally relevant group name. In a second step, we would then synchronize the members of that LDAP group and their contact details to a store in our application ) Appreciate any pointers.

• Developing ASP.Net User Control to be imported to SharePoint MOSS 2007

  - by Don Kirkham

  Apologies if this has been answered, but I could not find a similar question: I am developing a webpart for MOSS 2007. I am using WSPBuilder to built a visual webpart (ascx) and everything works fine, but the development/debug cycle is just painfully slow, so I'd like to know if it is possible (without being too painful) to develop the user control faster using an .Net Web Application project with all of the nice F5 debugging, then import the final product into my SharePoint visual webpart. The user control interacts with a LOB system (SQL) and does not reference the SharePoint API at all. (The reason I am building this as a webpart is because I don't need another web app to run this one page, so putting it into a webpart on a new webpart page on my existing site is the best solution IMO.) I would obviously need to import (reference?) my data access classes into my "temp" web app, but think that would not be too much trouble. I realize this will be extra effort to get this set up, but am thinking the payoff will be reduced development time of the actual user control using a little web application vs having to use the compile/build WSP/deploy WSP/reset ISS/test/make a change/repeat cycle that MOSS requires. (I guess SP2010/VS2010 has spoiled me with the native SharePoint tools available.)

• How to fix error - "@interface interfaceName : someEnumeration" gives error "cannot find interface '

  - by Paul V

  How can I solve "cannot find interface declaration 'someEnumeration', superclass of 'interfaceName'" error? What steps will reproduce the problem? Compiling Wsdl2ObjC Targeting groupwise.wsdl file Fixing non-valid file names of output csource code like ".h" + ".m" and objects inside source files Moving up one of the @interface BEFORE it was used futher in code! What is the expected output? Something working What do you see instead? 33 errors. "Inherited" from only 3 similar Inheritances of a typedef enum object by a class. All errors are typical: typedef enum types_StatusTrackingOptions { types_StatusTrackingOptions_none = 0, types_StatusTrackingOptions_None, types_StatusTrackingOptions_Delivered, types_StatusTrackingOptions_DeliveredAndOpened, types_StatusTrackingOptions_All, } types_StatusTrackingOptions; types_StatusTrackingOptions types_StatusTrackingOptions_enumFromString(NSString *string); NSString * types_StatusTrackingOptions_stringFromEnum(types_StatusTrackingOptions enumValue); @interface types_StatusTracking : types_StatusTrackingOptions { ... and here I'm having error "cannot find interface declaration for 'types_StatusTrackingOptions', superclass of 'types_StatusTracking'".

• "Subforms" associated with tree view in VB

  - by knomdeguerre

  I am using VB Express 2008 to demonstrate my ideas for an improved UI for an existing product for my colleagues at work. The current UI has a certain page with ten tabs, allowing the user to define up to ten "things". The available choices for each of the ten "things" are all the same. On each of the ten tabs, there is a checkbox to enable that definition. Generally, a user will never use more than 5 or 6 unique definitions, the rest will remain disabled. So far, my prototype has a tree view control with one branch to contain this list of definitions, Add and Delete buttons. My idea is: there is one sub-branch to start with (corresponding to the first tab in the current UI); if the user wants addtional definitions, they click Add and other branches are added to the tree view, up to maximum of ten. I think I should be able to create a "class" that has a sub-UI (like a sub-form in Access) along with behavior code, that can be instantiated with each press of the Add button; each instantiation's settings can be set independently and is displayed in the main UI form )in a panel or frame) when selected in the tree view. For example, suppose the user Adds to make a total of three definitions: the tree view now has three sub-branches, each of which presents the same sub-UI with settings that can be set specific to the selected sub-branch. I'm sure it's possible but not sure how to do it. I know a comprehensive "answer" might be complicated and long, but I may just need some quick hints to get underway - don't be shy! Thanks in advance!

• Word forms with too many ActiveX checkboxes load slowly.

  - by Luke

  Hi there, my company's software product has a feature that allows users to generate forms from Word templates. The program auto fills some fields from the SQL database and the user can fill in other data that they desire. So we have a .dotx template that holds the design of the form, and then the user gets the .docx file to fill out when they call it from our program. The problem we're having is that some of our users have been finding that the forms take an exceptionally long time to open up and then, once open, are so slow to respond (scroll around, etc) that they're unusable. So in my investigations so far, I've found out that the problem systems are one with lower powered CPUs (unfortunately it happens for systems above our system requirements) and the Word forms that cause the problems are ones with large amount of ActiveX style checkboxes on them. I verified that reducing the ActiveX checkboxes fixes the form loading problems. So I have the following questions about solutions (we're using Word 2007): 1) Is there any way to configure Word, or some other settings, so that there won't be such a strain opening a Word form with lots of ActiveX checkboxes? Any way of speeding up Word's opening? 2) Using Legacy style checkboxes instead of the ActiveX ones makes the forms load fine, but it looks like the user has to double-click the checkbox and change Default Value-Checked. Is there a way to configure it so that they can simply click on the checkbox to tick it? "Legacy Forms" checkbox as a name kind of worries me (Legacy…), does that mean a future version of word at some point wouldn't load the checkboxes because they're "legacy"? 3) Yes, it became clear to me after a little bit of research into solutions that Word is not the tool for the job for forms like I'm describing. InfoPath seems to be exactly what we should have been using all along but unfortunately I wasn't involved in the decision making or development of these forms, just tasked with coming up with a solution. I'd appreciate answers to any of these, or if anyone has any other ideas for solutions to this problem. Thanks

• When to drop an IT job

  - by Nippysaurus

  In my career I have had two programming jobs. Both these jobs were in a field that I am most familiar with (C# / MSSQL) but I have quit both jobs for the same reason: unmanageable code and bad (loose) company structure. There was something in common with both these jobs: small companies (in one I was the only developer). Currently I am in the following position: being given written instructions which are almost impossible to follow (somewhat of a fools errand). we are given short time constraints, but seldom asked how long work will take, and when we do it is always too long and needs to be shorter (and when it ends up taking longer than they need it to take, it's always our fault). there is no time for proper documenting, but we get blamed for not documenting (see previous point). Management is constantly screwing me around, saying I'm underperforming on a given task (which is not true, and switching me to a task which is much more confusing). So I must ask my fellow developers: how bad does a job need to be before you would consider jumping ship? And what to look out for when considering taking a job. In future I will be asking about documented procedures, release control, bug management and adoption of new technologies. EDIT: Let me add some more fuel to the fire ... I have been in my current job for just over a year, and the work I am doing almost never uses any of the knowledge I have gained from the other work I have been doing here. Everything is a giant learning curve. Because of this about 30% of my time is learning what is going on with this new product (who's owner / original developer has left the company), 30% trying to find the relevant documentation that helps the whole thing make sense, 30% actually finding where to make the change, 10% actually making the change.

• Python FTP grabbing and saving images issue

  - by PylonsN00b

  OK So I have been messing with this all day long. I am fairly new to Python FTP. So I have searched through here and came up w/ this: images = notions_ftp.nlst() for image_name in image_names: if found_url == False: try: for image in images: ftp_image_name = "./%s" % image_name if ftp_image_name == image: found_url = True image_name_we_want = image_name except: pass # We failed to find an image for this product, it will have to be done manually if found_url == False: log.info("Image ain't there baby -- SKU: %s" % sku) return False # Hey we found something! Open the image.... notions_ftp.retrlines("RETR %s" % image_name_we_want, open(image_name_we_want, "rb")) 1/0 So I have narrowed the error down to the line before I divide by zero. Here is the error: Traceback (most recent call last): File "<console>", line 6, in <module> File "<console>", line 39, in insert_image IOError: [Errno 2] No such file or directory: '411483CC-IT,IM.jpg' So if you follow the code you will see that the image IS in the directory because image_name_we_want is set if found in that directory listing on the first line of my code. And I KNOW it's there because I am looking at the FTP site myself and ...it's freakin there. So at some point during all of this I got the image to save locally, which is most desired, but I have long since forgot what I used to make it do that. Either way, why does it think that the image isn't there when it clearly finds it in the listing.

• What VC++ compiler/linker does when building a C++ project with Managed Extension

  - by ???

  The initial problem is that I tried to rebuild a C++ project with debug symbols and copied it to test machine, The output of the project is external COM server(.exe file). When calling the COM interface function, there's a RPC call failre: COMException(0x800706BE): The remote procedure call failed. According to the COM HRESULT design, if the FACILITY code is 7, it's actually a WIN32 error, and the win32 error code is 0x6BE, which is the above mentioned "remote procedure call failed". All I do is replace the COM server .exe file, the origin file works well. When I checked into the project, I found it's a C++ project with Managed Extension. When I checking the DLL with reflector, it shows there's 2 additional .NET assembly reference. Then I checked the project setting and found nothing about the extra 2 assembly reference. I turned on the show includes option of compiler and verbose library of linker, and try to analyze whether the assembly is indirectly referenced via .h file. I've collect all the .h file and grep all the files with '#using' '#import' and the assembly file itself. There really is a '#using ' in one of the .h file but not-relevant to the referenced assembly. And about the linked .lib library files, only one of the .lib file is a side-product of another managed-extension-enabled C++ project, all others are produced by a pure, traditional C++ project. For the managed-extension-enabled C++ project, I checked the output DLL assembly, it did NOT reference to the 2 assembly. I even try to capture the access of the additional assembly file via sysinternal's filemon and procmon, but the rebuild process does NOT access these file. I'm very confused about the compile and linking process model of a VC++/CLI project, where the additional assembly reference slipped into the final assembly? Thanks in advance for any of your help.

• Looking for a RESTful or SOAP pipeline between WordPress and InterWoven TeamSite

  - by deanpeters

  I've been Googling my brains out trying see if there's a simple way to bridge content to and from WordPress to and from TeamSite. I'm coming at this from the perspective of a WordPress developer. I see in the book "The Definitive Guide to Interwoven TeamSite" (http://bit.ly/d3z4wI) mention of objects for the Interwoven LiveSite product: com.interwoven.livesite.external.impl.RSS com.interwoven.livesite.external.impl.SOAP If I understand the above objects correctly, these allow me to instantiate objects of these data types, which after populating them via various method calls, allow me to render content using com.interwoven.livesite.external.ExternalCall ... but I'm not sure. Nor do I think this approach provides me the 2-way street I seek. As it stands now, from my limited understanding, it appears that the least path of resistance is deploying Interwoven's LiveSite with the existing TeamSite implementation so content can be both consumed and rendered via RSS ... an channel which WordPress can produce and consume; the latter with plugins such as wp-o-matic and/or feedpress. So the question is, does anyone out there have experience with a SOAP or RESTful API approach to InterWoven's TeamSite? If so, can I get some direction on documentation? Or is the addition of LiveSite + RSS the most feasible 2-way channel?

• Pro ASP.Net MVC 3 Entity Framework Sports Store tutorial

  - by gary7

  Following the tutorial in the book "Pro ASP.Net MVC 3 Entity Framework" in Chapter 9 - Image Uploads section; asks that the Product class be updated with two new columns - public byte ImageData, and public string ImageType. It also directs that the database be updated with these two columns via the server explorer. After these updates, the discussion directs that the Entity Framework Conceptual Model be updated via the SportsStore.EDMX file. This file does not exist in the source code for the project, and was not used in the project to begin with. Obvious errata for the book. Adding the ADO.NET Entity Data Model to the Project then overrides the EFProduct reposistory (conceptual model used throughout the project) which inherits from the interface IProductsRepository; and results in errors within the mapping. If the project is debugged after the columns are added, an error is thrown related to the new added columns. Has anyone resolved this issue in the project? I haven't found any solutions so far. Thanks!

• Multidimensional array (parent and childs)

  - by Juan

  I have a category system in a MySQL database with parents and childs. The database only stores the id of it''s immediate parent (or 0 if on root). Since the system allows multiple subcategories there are cases of multiple childs. For example [98] Storage [1] External [3] Pendrives [4] Portable hhdds [2] Internal [5] Sata hhdd [6] IDE hhdd [...] [99] Clothing The database would be id parent_id name 1 98 External 2 98 Internal 3 1 Pendrives 4 1 Portable 5 2 Sata 6 2 IDE 98 0 Storage 99 0 Clothing I also have a products table with a category id and I need to get a list of all the products in the first level of categories. For example: Product Category A 3 B 4 C 5 D 6 E 74 Should return 98: A, B, C, D 99: X, Y, Z... I'm stuck and I can't think of the logic to retrieve it in that way. I started by getting the IDs of all the categories that aren't in the first level by: while ($row = mysql_fetch_assoc($result)) { if ($row['parent_id'] != 0) { $level1[$i]['name'] = utf8_encode($row['categories_name']); $level1[$i]['id'] = $row['categories_id']; } $i++; } but I'm having a burnout and can't think of a way that would nest them. I thought some kind of while but it's infinite :P Any ideas please?

• Need help with version number schemes

  - by Davy8

  I know the standard Major.Minor.Build.Revision but there's several considerations for us that are somewhat unique -We do internal releases almost daily, occasionally more than once a day. -Windows Installer doesn't check Revision so that's almost moot for our purposes. -Major and Minor numbers ideally are only updated for public releases and should be done manually. -That leaves the Build # that needs to be automatically updated. -We want internal releases to be able to be performed from any developer's machine so that leaves out using x.x.* in Visual Studio because different numbers could be generated from different machines and each build isn't guaranteed to be larger than the previous. -We have about 15 or so projects as part of the product so saving the version numbers in SVN isn't ideal since every release we'd have commit all those files. Given those criteria I can't really come up with a good versioning scheme. The last 2 criteria could be dropped but meeting all of those seems ideal. A date stamp is insufficient because we might do more than one a day, and given the max size of Uint32 (around 64000) (Actually using WiX it complains about numbers higher than Int32.MaxValue) a date/time won't fit.

• Web API Getting Http 500 error : Issue Solved See Below

  - by Joe Grasso

  Here is my MVC Controller and everything is fine: private UnitOfWork UOW; public InventoryController() { UOW = new UnitOfWork(); } // GET: /Inventory/ public ActionResult Index() { var products = UOW.ProductRepository.GetAll().ToList(); return View(products); } Same method call in API Controller gives me an Http 500 Error: private UnitOfWork _unitOfWork; public TestController() { _unitOfWork = new UnitOfWork(); } public IEnumerable<Product> Get() { var products = _unitOfWork.ProductRepository.GetAll().ToList(); return products; } Debugging shows that indeed there is data being returned in both controllers' UOW calls. I then added a customer configuration in Global: public static void CustomizeConfig(HttpConfiguration config) { config.Formatters.Remove(config.Formatters.XmlFormatter); var json = config.Formatters.JsonFormatter; json.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver(); } I am still receiving an Http 500 in API Controller ONLY and at a loss as to why. Any ideas? UPDATE: It appears using lazy loading caused the problem. When I set the associated properties to NON-VIRTUAL the Test API provided the necessary JSON string. However, whereas before I had the Vendor class included, I only have VendorId. I really wanted to included the associated classes. Any ideas? I know there are alot of smart people out there. Anyone?

• UIButton stops responding after going into landscape mode - iPhone

  - by casey

  I've been trying different things the last few days and I've run out of ideas so I'm looking for help. The situation is that I'm displaying my in-app purchasing store view after the user clicks a button. Button pressed, view is displayed. The store shows fine. Inside this view, I have a few labels with descriptions of the product, and then below them I have the price and a Buy button which triggers the in-app purchase. Problem is when I rotate the phone to landscape, that Buy button no longer responds, weird. Works fine in portrait. The behavior in landscape when the I touch the button is nothing. It doesn't appear to press down and be selected or anything, just not responding to my touches. But then when I rotate back to portrait or even upside down portrait, it works fine. Here is the rough structure of my view in IB, all the rotating and layout is setup in IB. I set the autoresizing in IB so that everything looks ok in landscape and the Buy button expands horizontally a little bit. The only layout manipulation I do in my code is after loading, I set the content size of the scroll view. File Owner with view set to the scrollView / scrollView ----/ view --------/ label --------/ label --------/ label --------/ label --------/ label --------/ label --------/ label --------/ label --------/ uibutton (Buy) After orientation changes I printed out the userInteractionEnabled property of the scrollView and the button, and they were both TRUE at all orientations. Ideas? Or maybe some other way of displaying a buy button that won't be nonfunctional? I've already begun a branch that plays with a toolbar and placing the buy button there, but I can't seem to get the bar to stay in place while scrolling.

• How to implement message queuing and handling in AWS with NServiceBus

  - by Pete Lunenfeld

  I am creating a new ASP MVC order application in the Amazon (AWS) cloud with the persistence layer at my local datacenter. I will be using the CQRS pattern. The goal of the project is high availability using Queue(s) to store and forward writes (commands/events) that can be picked up and handled asynchronously at my local datacenter. Then, ff the WAN or my local datacenter fails, my cloud MVC app can still take orders and just queue them up until processing can resume. My first thought was to use AWS SQS for the queuing and create my own queue consumer/dispatcher/handler in my own c# application to process the incoming messages/events. MVC (@ Amazon) -- Event/POCO -- SQS -- QueueReader (@ my datacenter) -- DB Then I found NServiceBus. NSB seems to handle lots of details very nicely: message handling, retries, error handling, etc. I hate to reinvent the wheel, and NServiceBus seems like a full featured and mature product that would be perfect for me. But on further research, it does NOT look like NServiceBus is really meant to be used over the WAN in physically separated environments (Cloud to my Datacenter). Google and SO don't really paint a good picture of using NServiceBus across the WAN like I need. How can I use NServiceBus across the WAN? Or is there a better solution to handle queuing and message handling between Amazon an my local datacenter?

• Custom Server to communicate with my software?

  - by Zachary Brown

  I am working on a major project that I need for work. I am working on a project that requires software validation. I would like this to be handled by a custom server I will write in Python, this server will be the "gateway" between the user and product activation. The software program will be purchased from other companies in volume licensing. So this is what I need the server to do: 1). The user clicks to activate their software. (easy, all is good so far) 2). The software gets the distributor's id from another online server. ( this is also easy, and already coded.) 3). Then, the software asks my custom server if the distributor is allowed to activate anymore copies of the software. 4). The server will then check ( an online encoded text file ) to see if the distributor can or can't. If they can, it will tell the software that registration can proceede, at which point the software will pass the software serial number to the server. I have done my best to explain what I am trying to accomplish, but if something is not quite sensible, please let me know. Thanks to all members of Stackoverflow.com for the help in the past, and those who will help me now. I am using Python 2.6 Win. XP Home Edition
