• SharePoint WSS 3.0 - Fastest approach to build data-bound forms?

  - by Rusty Scupper

  Pardon the vague question, but I've just inherited a project to build a couple dozen forms pulling data from a SQL 2005 database. The forms are mostly standard database lookups with just a couple updates so the data layer is very simple -- I'm the DBA -- but we just recently started using SharePoint WSS 3.0 for a departmental web site and I would prefer to integrate these forms into WSS rather than build a separate standalone ASP.NET app. I'm hoping there is some RAD framework out there that integrates with WSS for data bound forms. I've been searching online, but haven't found anything very promising and the data viewer web part in SharePoint Designer looks complicated to integrate with an external SQL database. TIA, Rusty

• How to convert an Info.plist file from mac os project to iphone project?

  - by Tom Pace

  I am developing an app for the iPhone OS devices, and am using a third-party engine which is not well documented but I've made great progress with it anyway. The problem: The engine's developer strongly urges extending from the existing template projects bundled with the engine, but the engine's Info.plist files are Mac OSX project Info.plist files. This is an iPhone engine, and so I cannot understand why the Info.plist file is structured to take keys for Mac OS apps, but that's how it is. I did a FileMerge comparison to ensure there was nothing within the file itself that defined its use for one OS or the other, so I guess it's defined somewhere in the project settings. Edit - Opening the plist file in Xcode or Property List Editor and then trying to add a key such as "Icon already includes gloss and bevel effects" will not work in this iPhone project because it is not in the list. However, "Cocoa Java Application" and others are available!

• Listing like appstore in firefox or any other browser for windows/desktop linux

  - by jenso

  A little question about the listing in iPhone OS and some other applications, and possibly in Android Market. When listing the apps, it fills the list in an automatic process, when reaching or is near to reach the end. My question is: How is that written in iPhone applications. But the main question is: Is that possible to make for Firefox users with Javascript, Ajax or possibly any other language? Been looking a little bit in documentation but havent found anything useful, maybe I just havent looked enough edit: Found it for Android - http://stackoverflow.com/questions/1917773/dynamic-listview-in-android-app Still looking for same futures for a Windows browser tho out

• vs2008 attach to process, can't see which process

  - by Mafti

  Hi, In vs2003 (and vs2005(not sure about that)) when I attached to a process, before actually attaching I could see which process were running under w3wp (I have a couple of websites running locally) so I knew which exact .net application I was about to debug. however in vs2008 the window doesn't show up anymore.. now I have to attach it, come to the conclusion it was the wrong process, stop debugging and attach it to the other process (if I haven't forgot teh processid :P ) Is there a way to "enable" that interesting window to see with .net apps are runnig in that specific w3wp process? or am i missing something obvious?

• Checking if an object has been released before sending a message to it

  - by Tom Irving

  I've only recently noticed a crash in one of my apps when an object tried to message its delegate and the delegate had already been released. At the moment, just before calling any delegate methods, I run this check: if (delegate && [delegate respondsToSelector:...]){ [delegate ...]; } But obviously this doesn't account for if the delegate isn't nil, but has been deallocated. Besides setting the object's delegate to nil in the delegate's dealloc method, is there a way to check if the delegate has already been released just incase I no longer have a reference to the object.

• Service for converting SWFs with ActionScript to Video (MPEG, AVI, or MOV)

  - by pcooley

  The SWF files generated by our application are a basic template that reference external resources (images, and textual data) that actionscript uses to fuel the display. Thus the SWF is responsible for the creative layout of the screen the flash player. It is the results of this actions script, images, and textual data that need to be converted to a video format. Is anyone familiar with an online service that would be able to convert such .swf files that our site generates to a video format (say .avi, .mpeg, .mov). Or an application? Note: A more common case might be the conversion of an embedded FLV to a video, but this is not our need

• Is *not* using the asp.net membership provider a bad idea?

  - by EJB

  Is it generally a really bad idea to not use the built-in asp.net membership provider? I've always rolled my own for my asp.net apps (public facing), and really have not had any problems in doing so. It works, and seems to avoid a layer of complexity. My needs are pretty basic: once setup, the user must use email address and password to login, if they forget it, it will be emailed back to them (a new one). After setup there is little that needs to be done to each user account, but I do need to store several extra fields with each user (full name, telephone and a few other fields etc). The number of users that required login credentials are small (usually just the administrator and a few backups), and everyone else uses the site unauthenticated. What are the big advantages that I might be missing out on by skipping the asp.net membership provider functionality?

• iPhone noob - different method types?

  - by codemonkey

  My apologies in advance for what is probably a really dumb question. I'm familiar (or at least getting familiar) with instance and class methods in objective-c, but have also seen method implementations that look like this: #import "Utilities.h" #import "CHAPPAppDelegate.h" #import "AppState.h" @implementation Utilities CHAPPAppDelegate* GetAppDelegate() { return (CHAPPAppDelegate *)[UIApplication sharedApplication].delegate; } AppState* GetAppState() { return [GetAppDelegate() appState]; } @end What are these? While I'm sure this is documented somewhere, I don't know what term to use in searching for an explanation of what's being done here. I like the syntax methods like this let me use when calling them, but I'm not sure exactly what I'm doing, what the implications are, how to send parameters to these types of functions, etc? To clarify how I ended up in this position, I started using these methods in a "utilities" class of mine after reading some online blog describing the author's preference for declaring these functions this way. Now I can't seem to track down a more detailed explanation of what exactly the differences are, etc.

• Is is possible to use transparency in an iPhone app icon?

  - by yukon

  I created a 57X57 Circle-shaped icon (without shine) which has transparency outside of the circle-shape for my app. I can successfully install the app on Simulator and iPhone. It works fine, and looks great. However, can I submit an icon with transparency to Apple. Will they accept it? I can't find any apps which have transparency in their icon... instead they use a kind of pseudo-transparency - a jet black background with no shine.

• How do i connect with dart community to suggest something

  - by Muhammad Umer

  I am new to this stackoverflow and programming. So HI!!!! What i hope to do is tell something that i think is important to Dart community. If somehow it was possible to code android and or iphone apps using dart that would be very awesome and same for Dart.... There is one path, that is making program in dart compiling it to javascript and then making app using Adobe air..... .But looks inefficient. so is there any other way which i am unaware of, via which i can build an android app at least.. using dart i know you can build an app, using javascript..and css+html...so i am looking for html+css+dart. It'd be cool if adobe air supports dart language directly.

• Cake PHP Error: Make sure you have created index.ctp (???)

  - by Louis Stephens

  I was just starting to learn cakephp today by going through a "blog tutorial". I created my blog_controller.php and then created a folder named 'blog' with the apps/views/ structure. The next step in the tutorial was to create the index.ctp file within the blog folder under views. In the tutorial it declares that all error messages should be gone. However, I still receive an error message: Error: The view for BlogController::index() was not found. Error: Confirm you have created the file: /Users/trippstephens/Dropbox/cakephp-cakephp1x-348e5f0/app/views/blog/index.ctp For the life of me, I can not figure out what I have done wrong. I am running cakephp under MAMP and it "installed" successfully. Any help would be appreciated.

• Extra characters Extracted with XPath and Python (html)

  - by Nacari

  I have been using XPath with scrapy to extract text from html tags online, but when I do I get extra characters attached. An example is trying to extract a number, like "204" from a <td> tag and getting [u'204']. In some cases its much worse. For instance trying to extract "1 - Mathoverflow" and instead getting [u'\r\n\t\t 1 \u2013 MathOverflow\r\n\t\t ']. Is there a way to prevent this, or trim the strings so that the extra characters arent a part of the string? (using items to store the data). It looks like it has something to do with formatting, so how do I get xpath to not pick up that stuff?

• How necessary is using PHP filters?

  - by Jamie

  I'm a relatively newbie to PHP and just making my way through the W3Schools tut. The tut makes a big point of saying you must always filter external data (i.e. cookies, form data etc). I'm writing a fairly simple system that talks with a third party Joomla extension. It's at a prototype stage where I'm just wanting to demonstrate the functionality in a minimum viable product. Basically, I'd like to know... what's the worst that could happen in I don't filter content. Are we talking 'I might get a bunch of spam', or 'a good hacker could get root server access'? Have hunted around online, but would love any of your experience / insight on the matter!

• Helping managers and customers understand SOA

  - by David

  I frequently hear Service-Oriented Architecture (SOA) being tossed around as a buzzword among non-technical customers or program managers with little concern or understanding for what it actually entails (example: "Can I buy a SOA?"). There's also a lot of misinformation about SOA (example: "Only web apps can use SOA") and a general lack of understanding for its capabilities (example: "SOA can make your make all of your data work together"). What are some key facts that you, as someone who understand the technical side of SOA, use to educate program managers on the appropriate use and understanding of SOA? What's the best way to set the record straight with non-technical folks?

• iPhone simple commercial barcode reader via camera

  - by user347635

  Hey all, I've done some iPhone programming (safely midlevel) and now a requirement has come up for us to write a barcode reader that uses the iPhone camera. This is not for shopping or the general public but will be for internal use. My first thought was to simply programatically take a picture, upload it to server, and have a web service or something similar handle the heavy lifting of extracting the numbers out of the bar code. However I recently installed some apps already available on the iPhone that read bar codes, refer you to shopping sites, etc. and they seem to use the video camera to identify barcodes and extract the numbers. Does anyone know how this is being done or could point me to some open source or sample code?

• Seam app with JBoss 'minimal' Config?

  - by Shadowman

  I'd like to improve the performance of my Seam apps and JBoss appserver, particularly by removing things that aren't necessary in the standard configuration. Ideally, I'd like to be able to run it using the "minimal" profile. Can anyone give me any guidance as to what is needed to run a Seam app using "minimal"? Here are the kind of things my app requires: JPA, using Hibernate with a PostgreSQL backend EJB3 JSF (RichFaces/Facelets) E-mail, eventually, although not required at this particular moment I'll be developing my app using JBoss Tools on Eclipse, so I would also need anything that is required by the tools for development and deployment. I've found that the default configuration just has too many additional components and features installed by default, and that greatly affects performance when I'm trying to develop. Any help you can give would be great! Thanks!

• Creating a custom widget using django for use on external sites

  - by ajt

  I have a new site that I am putting together and part of it has statistics for the site's users. I would like to create a widget that others can use on another website by invoking javascript that reads data from my server and shows that statistics for a given user, but I am having a hard time finding specific tutorials that covers this in django. I have seen the link at Alex Maradon's site [0], but it looks to me like that is passing html back to the widget and I am having a hard time figuring out how to do this using something like xml. Are there any django apps for doing this or does anyone know of good how-tos? [0] http://alexmarandon.com/articles/web_widget_jquery/

• Array in Bash Not Found

  - by Waffle

  I am trying to declare an array in bash, but when the code is run it says it cannot find the array. I have tried to write out the declaration of the array in several different ways, but it seems no matter how I try to declare it I cannot get it to work. I originally tried to declare it as such: candidate[1]= 0 candidate[2]= 0 candidate[3]= 0 The error messages that are returned are: votecalculation.sh: 13: candidate[1]=: not found votecalculation.sh: 14: candidate[2]=: not found votecalculation.sh: 15: candidate[3]=: not found After this I tried another solution I found online: ARRAY=( 'can1' 'can2' 'can3' ) When that is used it returns this error: votecalculation.sh: 12: Syntax error: "(" unexpected I am new to Bash and am getting really confused about arrays. Is there some specific way I need to declare an array or am I just going about it completely wrong?

• Messaging strategies to connect different systems

  - by n002213f

  I have a system to handle Applications online and a different system to send SMS/Email notifications to applicants on completion using web services. I can't guarantee the availability of the SMS/Email gateway. Option 1 After an application is complete, place a message on a JMS queue. A Message Driven bean receives the message and make a call for the web service, if it fails leave the message on the queue. I suspect (please correct if incorrect) that if the gate way is offline the continuosly try to send the message which might use up valuable resources. Can the above option be refined are are there any other messaging strategies that can be used?

• Securing files on IPhone

  - by clearbrian

  Hi Is there a way to decompile the binary from an IPhone app. I jailbroke my IPhone and was surprised to find other app's dbs wide open to be copied. So I exported my most important table and hardcoded it into code. Instead of loading table into array from a db I just generated code to fill the array and kept only the most basic DB info so relationships still work. Took a while but now works fine. I was just wondering am I safe, could someone decompile the binary for the app easily and extract the data. In Java its easy to decompile *.class files though thats bytecode where I presume iphone apps are more low level. I know IPhone sdk 4 can mark files as secure. Anyone know can this be overridden by jailbreaks or is this an unix lock?

• How to approach local database management via Flex/Air App

  - by Damon

  I am planning on using Flash Builder 4/Flex to write an AIR application which is primarily based around recording, storing and analyzing data. I'll be creating charts etc that need to update in almost real time. It's essential to me that the application be able to function without an internet connection so I need a local database of some variety, but I would also eventually like to build in online synchronization of the data where either database can be update each other based on newer information. Moreover, some type of encryption would definitely be welcome, and speed is a large concern With all that in mind, what is my best approach to try and avoid headaches down the road?

• What's the best way to write a maintainable web scraping app?

  - by Benj

  I wrote a perl script a while ago which logged into my online banking and emailed me my balance and a mini-statement every day. I found it very useful for keeping track of my finances. The only problem is that I wrote it just using perl and curl and it was quite complicated and hard to maintain. After a few instances of my bank changing their webpage I got fed up of debugging it to keep it up to date. So what's the best way of writing such a program in such a way that it's easy to maintain? I'd like to write a nice well engineered version in either Perl or Java which will be easy to update when the bank inevitably fiddle with their web site.

• What to keep in mind when creating your own custom web services API?

  - by John Conde

  I have created a website which allows users to sign up for, and use, an online service. To help promote the website we will be have resellers who will be offering their own branded services through us. The initial plan is to allow resellers to place registration, login, and lost password forms on their own website and use an API created by us to handle these requests. I have begun outlining how I expect the API to work (and starting documenting it as well) and I want to make sure I get it right, or as close to right, as I can from the beginning as I know once you have declared a public API you want to avoid changing that API at all costs. So far I have decided: To have the user pass their account credentials with each request To require SSL for all requests What else should I be keeping in mind?
