• iPhone: Core Data: Updating a pre-filled database in future app versions.

  - by Cuzog

  I am creating an app with a database of information that needs to be pre-filled. This data will change in future versions. In the same database, I also need to store user editable information since that user edited data directly relates to the pre-filled data. My question is, if I'm pre-filling the database by creating a duplicate data model in a second app and copying over the core data file before release, how would I handle updates to that data in future versions of the app without destroying the user's existing data? Do the core data migration methods handle this, or must I write custom methods to programatically handle the merge at first app launch?

• Automating WebTrends analysis

  - by tridium

  Every week I access server logs processed by WebTrends (for about 7 profiles) and copy ad clickthrough and visitor information into Excel spreadsheets. A lot of it is just accessing certain sections and finding the right title and then copying the unique visitor information. I tried using WebTrends' built-in query tool but that is really poorly done (only uses a drag-and-drop system instead of text-based) and it has a maximum number of parameters and maximum length of queries to query with. As far as I know, the tools in WebTrends are not suitable to my purpose of automating the entire web metrics gathering process. I've gotten access to the raw server logs, but it seems redundant to parse that given that they are already being processed by WebTrends. To me it seems very scriptable, but how would I go about doing that? Is screen-scraping an option?

• Java: JAX-WS passing authentication info to a call to webservice

  - by agnieszka

  I am using JAX-WS. I am connecting to .NET webservice that requires authentication. I first call the Authentication.asmx so that I can be authenticated. The call returns me a LoginResult that contains a cookie name. Then I call another webservice and I need to somehow pass this cookie or a cookie name. and I don't know how. Here is the code: //first service that returns login information Authentication auth = new Authentication(new URL("the_url"), new QName("http://schemas.microsoft.com/sharepoint/soap/", "Authentication")); LoginResult result = auth.getAuthenticationSoap().login(HTTPuserName, HTTPpassword); //i need to pass cookie or cookie name or any other login information to call to this service Copy copyService = new Copy(new URL("service_url"), new QName("http://schemas.microsoft.com/sharepoint/soap/", "Copy")); BindingProvider p = (BindingProvider) copyService.getCopySoap();

• Schemas and tables versus user-ids in a single table using PostgreSQL

  - by gvkv

  I'm developing a web app and I've come to a fork in the road with respect to database structure and I don't know which direction to take. I have a database with user information that I can structure one of two ways. The first is to create a schema and a set of tables for each user (duplicating the structure for each user) and the second is to create a single set of tables and query information based on user-id. Suppose 100000 users. Here are my questions: Considering security, performance, scalability and administration where does each choice lie? Would the answers change for 1000000 or 10000? Is there a set of best practices that lead to one choice or the other? It seems to me that multiple schemas are more secure since it's trivial to restrict user privileges but what about performance and scalability? Administration seems like a wash since dumping (and restoring) lots of schemas isn't any more difficult than dumping a few.

• Blank space after file extension -> weird FileInfo behaviour

  - by Axarydax

  Somehow a file has appeared in one of my directories, and it has space at the end of its extension - its name is "test.txt ". The weird thing is that Directory.GetFiles() returns me the path of this file, but I'm unable to retrieve file information with FileInfo class. The error manifests here: DirectoryInfo di = new DirectoryInfo("c:\\somedir"); FileInfo fi = di.GetFileSystemInfos("test*")[0] as FileInfo; //correctly fi.FullName is "c:\somedir\test.txt " //but fi.Exists==false (!) Is FileInfo class broken? Can I somehow retrieve information about this file? I really don't know how did that file appear on my file system, and I am unable to recreate some more of them. All of my attempts to create a new file with this type of extension have failed, but now my program is crashing when encoutering it. I can easily handle the exception when finding the file, but boy am I curious about this!

• Printing pdf without opening

  - by Marius

  Hello there, I want to open a PDF-print dialog (not regular browser dialog) without visually opening the document so that I can print a pdf without having the header and footer information from a regular webpage print. I know this is possible, because I have seen it in the past on a postal service website for printing postage labels, but cannot remember where. As far as I know, printing it from an iframe doesnt work, as it only opens regular browser print dialog and gives me ugly page and url information: frames['name'].focus(); frames['name'].print(); Thank you for your time. Kind regards, Marius

• Download a file from one ASP.NET web application to other (given the credentials)

  - by Tom S.

  Hi everybody! Im working on a asp.net 3.5 web application (C#), where i have a file with some information that is updated frequently, and only few accounts can access to it (the application is using the asp.net authentication system, stored in a SQL database). My task is to parse that file, so i made a small parser (another web app) a to show the information in a more friendly way. However, everytime i want to parse it, i need to enter in the application with one of those accounts, download the file, put in the parser's folder. Is there any way to, given the username and password, download the file directly from the parser application and use that one? Thanks in advance

• Upload documents using email and mapping properties of documents

  - by stranger001

  Hi, We have a requirement to upload documents to a specific SharePoint document library when a document is sent via email to a specific email address. I think SharePoint has this feature available. What I would like to know more importantly is mapping the information in the body of the email to the custom properties of the document. For example, if a custom field (property) is added to the document in SharePoint say - "Year". I provide the value of this property within the body of the email and attach the document in email. Is it possible that the provided value in the body of the email for the property is updated in SharePoint when the document is uploaded to SharePoint through email? We are using SharePoint 2007. Appreciate any information on this. Thanks

• Appending Dataset in Core Data execution of Update through iTuneStore

  - by Yoon Lee

  So I have completed my code work. This is first time releasing the app through iTuneStore. Current state of reading Core Data (.sqlite) file is already prefetched (already has information like apple's 'Reciepie' program). Assuming I have successfully released through apple store, and decide to update my application to existing users. Say I have sqlite contents but it contains bit more information than previous SQLite file under same structure. Question 1. Every time update held to the existing user, does it removes previous ones and move new updated application? Question 2. if it is not, then HOW can I append the existing sql value?

• Which development Language is best suited to Network Inventory

  - by dastardlyandmuttley

  Dear stackoverflow I hope this is the corrcet type of question for stackoverflow to consider I would like to develop a "Hard Core" application that performs Network Inventory. High level requirements are Work on Windows and UNIX networks it has to be extremly performant it has to be 100% accuarate (massively) scalable and fun to write The sort of details I am after is manufacturer and versions of all major workstation hardware components such as motherboard, network card, sound card, hard drives, optical drives, memory, BIOS details, operating system information etc. I dont want to have to distribute a client on each workstation to collect the information although i will require automatic worksattion discovery I would value your thoughts on the best development language to employ I know there are products such as NEWT and stuff like nmap... I would like to do this type of technical programming myself "from scratch" Warm Regards DD

• iPhone modal view inside another modal view?

  - by Rick

  My App uses a modal view when users add a new foo. The user selects a foo type using this modal view. Depending on what type is selected, the user needs to be asked for more information. I'd like to use another modal view to ask for this extra information. I've tried to create the new modal view like the first one (which works great) and it leads to stack overflow/“Loading Stack Frames” error in Xcode. Am I going about this in completely the wrong way i.e. is this just a really bad idea? Should I rethink the UI itself? UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:addController]; [self presentModalViewController:navigationController animated:YES];

• Drawing the UIPicker values from multiple components?

  - by Rob

  I have the UIPicker setup with multiple components and a button below it. Depending on what the user has chosen with the UIPicker determines which new view will be loaded but I am having trouble determining how to extrapolate the information from the picker itself. Right now I have this method being called when the button is pressed: - (IBAction) buttonPressed { if (component:1 == 1 && component:2 == 1) { //Load the view number 1. } else if (component:1 == 2 && component:2 == 1) { //Load the view number 2. } else { //Load the view number 3. } } I obviously know that my code is wrong but I hope it gets the point across. I have multiple components and I need to figure out how to use the information that the user is scrolling to on the picker to determine which view to move to. (I know how to load the views, I just commented those in the code to illuminate the problem areas better.)

• What are some tips for troubleshooting builds of complicated software?

  - by Goose Bumper

  Sometimes I want to build Python or GCC from scratch just for fun, but I can't parse the errors I get, or don't understand statements like "libtool link error # XYZ". What are some tricks that unix/systems gurus use to compile software of this size from scratch? Of course I already do things like read config.log (if there is one), google around, and post in newsgroups. I'm looking for things that either make the process go smoother or get me more information about the error to help me understand and fix it. It's a little tough to get this information sometimes, because some compile bugs can be quite obscure. What can I do at that point?

• SharePoint Virtual Directories Sitemap

  - by Edison

  I have created and asp.net web site utilizing a web.sitemap file to help with navigation. The site needs to be deployed within a virtual directory inside of our SharePoint intranet site. The problem that I am running in to is that when I request the SiteMap.CurrentNode property, it is returning information from SharePoint's sitemap. Specifically, when i try to get my sitemap's title or description, I am getting information from SharePoint. I have tried re-naming my sitemap and declaring a new Sitemap provider within the web.config. After creating the new sitemap provider and requesting the SiteMap.currentNode, I receive an error message saying that it can't find the web.sitemap file. Any help you can provide would be greatly appreciated.

• C++ Win32 Unhandled Exception Handler

  - by uray

  currently I used SetUnhandledExceptionFilter() to provide callback to get information when an unhandled exception was occurred, that callback will provides me with EXCEPTION_RECORD which provides ExceptionAddress. [1]what is actually ExceptionAddress is? does it the address of function / code that gives exception, or the memory address that some function tried to access? [2]is there any better mechanism that could give me better information when unhandled exception occured? (I can't use debug mode or add any code that affect runtime performance, since crash is rare and only on release build when code run as fast as possible) [3]is there any way for me to get several callstack address when unhandled exception occured. [4]suppose ExceptionAddress has address A, and I have DLL X loaded and executed at base address A-x, and some other DLL Y at A+y, is it good to assume that crash was PROBABLY caused by code on DLL X?

• Is it possible to get code coverage data for a GWT web app running tests from the web browser?

  - by jeff

  I am not sure if this is possible but I would like some way to get code coverage information for tests that are written in Quick Test for our GWT based web app. It does not seem like there is any solution because the Quick Test Pro tests are testing against the GWT compiled app and not the original java code in which the app was written. I suppose I could get coverage data on the javascript that the GWT compiler creates, but there would be no way for me (that I know of) to map this information back to the original java code. Is there some way to do this?

• Revision Materals, other than book, for MCTS 70-536 Exam

  - by Damien

  Does anyone have any recommendations on revision materials for the MCTS 70-536 exam other than the monstrosity that is the official book? I am finding it very difficult to absorb the amount of information in the book in such a passive way (i.e just reading) it's not going in. My current approach has been to use the practise tests and make notes on the questions I was unsure about but given the wide varity of questions that could come up I am not sure if this is the correct way to do things. So is there someone with more condensed, bite-size, information to take in. Maybe videos or podcasts? Cheers!

• When to use Spring Integration vs. Camel?

  - by ngeek

  As a seasoned Spring user I was assuming that Spring Integration would make the most sense in a recent project requiring some (JMS) messaging capabilities (more details). After some days working with Spring Integration it still feels like a lot of configuration overhead given the amount of channels you have to configure to bring some request-response (listening on different JMS queues) communications in place. Therefore I was looking for some background information how Camel is different from Spring Integration, but it seems like information out there are pretty spare, I found: http://java.dzone.com/articles/spring-integration-and-apache (Very neutral comparison between implementing a real-world integration scenario in Spring Integration vs. Camel, from December 2009) http://hillert.blogspot.com/2009/10/apache-camel-alternatives.html (Comparing Camel with other solutions, October 2009) http://raibledesigns.com/rd/entry/taking_apache_camel_for_a (Matt Raible, October 2008) Question is: what experiences did you make on using the one stack over the other? In which scenarios would you recommend Camel were Spring Integration lacks support? Where do you see pros and cons of each? Any advise from real-world projects are highly appreciated.

• NSZombieEnabled hides EXC_BAD_ACCESS error entirely

  - by David Liu

  So I have a subclass of a UIView that starts causing EXC_BAD_ACCESS errors when I go through a specific set of conditions (run on iPad instead of iPhone or simulator, first login only). It throws the exception when the UIView subclass gets deallocated, during the last line, where I have [super dealloc]. I heard about using NSZombieEnabled, so I tossed that on to see if I could get any more information about it, but now it hides the error completely! Does anyone know a bit more about this type of situation? I thought NSZombie would start spewing stuff into my console like before, but I'm hoping that the nonexistance of errors would tell me some sort of information as well.

• How can I pass a dynamic backing bean into a JSF 2.0 page using facelets?

  - by kgrad

  Hi, I am using a JSF 2.0 to create a web app (purely jee6, without spring/seam etc.). I would like to have a single xhtml page but pass the proper backing bean / entity into it. For example, I would like to be able to edit a user other than the logged in user, I have a user edit page which displays the information of the logged in user (being tracked by my session), I would like to instead pass in a user selected from a list and edit that user's information, without switching the user that is stored in the session or creating a separate xhtml page (violating DRY). The "best" way I can see to achieve this would be to reuse the exact same xhtml page that I am using to display the logged-in-user's edit page, but simply pass in a different entity in some way. Perhaps calling the setter in the backing bean before redirecting to the page (if this is even possible) or some other solution that does not violate DRY. Perhaps I have designed this all wrong, is there a way to pass in entities to JSF pages? thanks.

• How to avoid manual editing of manifest file

  - by Atara

  My application uses isolated activeX (outer), that depends on another activeX (inner), both are using registration-free-com. The generated manifest file contains only the information for the outer activeX. (probably because vs cannot know that the outer activeX is using inner activeX ) When I re-build my project, I always need to manually add the information for the inner activeX to the manifest file, otherwise the application only shows the outer, without the inner. Is there a way to inform visual studio (2008) that I do not want it to re-generate the manifest file for each build? Will I have such option if I upgrade to VS2010 ? Thanks, Atara

  Hi guys, i was trying to do a Cell Editing based on this documentation http://www.trirand.com/jqgridwiki/doku.php?id=wiki:cell_editing I have two questions: How can i get the Index of my row posted to the server: The information i'm getting posted is the following: a) value of the cell b) RowId The thing is that the rowId doesn't help me. I need the actual Id of the information I'm displaying so i can do the server update with that Id. colNames: ['Id', 'Codigo', 'Nombre'], colModel: [ { name: 'Id', index: 'Id', width: 50, align: 'left', hidden: true }, { name: 'Codigo', index: 'Codigo', width: 55, align: 'left', editable: true, editrules: { number: true} }, { name: 'Nombre', index: 'Nombre', width: 200, align: 'left' }], I need the value of the column 'Id' to do my update. 2.I don't understand in the documentation how to manage an error from the server, so I can display the error message. Thank you very much! Notes: a) I've already asked in the forum of trirand, but no one reply it to me. b) If anyone has done this, it would help if help me pasting the code. c) I'm working on MVC 2 Asp.net
