• Avoid writing SQL queries altogether in SSIS

  - by Jonn

  Working on a Data Warehouse project, the guy that gave us the tutorial advised that we stick to using SQL queries over defining a lot of data flow transformations, citing points like it'll consume a lot of memory on the ETL box so we'd rather leave the processing to the DB box. Is this really advisable? Where's the balance between relying on GUI tools over executing a bunch of SQL scripts on your Integration package? And honestly, I'd like to avoid writing SQL queries as much as I can.

• SNMP: OID to use when writing custom MIBs

  - by justcatchingrye

  If you are writing your own MIB for a bespoke application, is there a 'best practice' for which branch you should use. I'm thinking of something analogous to private IP addresses, that can be used within enterprises, without conflicting with Registered IP addresses I have been asked to make a suggestion, as I advised Application Developers that they should not use OIDs under .1.3.6.1.4.1.111 - This is the Oracle branch

• Writing SDK documentation, need useful beginner tutorials

  - by David Rutten

  I'm currently writing SDK documentation for one of our products, but for obvious reasons I don't want to talk about the essentials of OOP. Does anyone know any good online teaching material that explain (aimed at absolute beginners) concepts such as classes, inheritance, constructors, instances etc.? Preferably urls that are likely to survive for a couple of years to come... It's a DotNET SDK and we're including only VB and C# samples, so C++ or Delphi or Lisp material is not that useful.

• C check before writing to closed pipe

  - by Gary

  Is there an easy way to check if a pipe is closed before writing to it in C? I have a child and parent process, and the parent has a pipe to write to the child. However, if the child closes the pipe and the parent tries to read - I get a broken pipe error. So how can I check to make sure I can write to the pipe, so I can handle it as an error if I can't? Thanks!

• Calling and writing jquery/javascript functions

  - by Ankur

  I think I have not got the syntax correct for writing a javascript function and calling it to assign its return value to a variable. My function is: getObjName(objId){ var objName =""; $.ajax( { type : "GET", url : "Object", dataType: 'json', data : "objId="+objId, success : function(data) { objName = data; } }); return objName; } I am trying to call it and assign it to a variable with: var objName = getObjName(objId); However Eclipse is telling me that "the function getObjName(any) is undefined"

• Writing a spec for helper with Ruby on Rails and RSpec

  - by TK

  I have been writing specs for controllers and models, but I have never written a helper spec. I have no idea where I start. I have the following snippet in application_helper.rb def title(page_title) content_for(:title) { page_title } end How should I write a helper spec on the code? Also if there's any open-source Rails app to show good helper testing/specing, do let me know.

• writing large excel spreadsheets

  - by pstanton

  has anybody found a library that works well with large spreadsheets? I've tried apache's POI but it fails miserably working with large files - both reading and writing. It uses massive amounts of memory leaving you needing a supercomputer to parse or create a 20+mb spreadsheet. Surely there is a more memory efficient way and someone has written it?!

• Writing a function for UIAlertView?

  - by worchyld

  I'm sick of writing basic UIAlertView's, ie: UIAlertView *alert = [[UIAlertView alloc] initWith...]] //etc Instead of doing this, is it possible to put all this in a "helper" function, where I can return the buttonIndex, or whatever an alert usually returns? For a simple helper function I guess you could feed parameters for the title, message, I'm not sure whether you can pass delegates in a parameter though, or bundle info. In pseudo-code, it could be like this: someValueOrObject = Print_Alert(Title="", Message="", Delegate="", Bundle="") // etc Any help on this would be great. Thanks

• Writing exceptions in multihreaded windows service to event log

  - by Ziplin

  I have a multithreaded windows service that will unpredictably stop running once every 24 hours or so. I am writing to the event log and that's going through just fine, but whenever the service crashes there are no messages in the event log (even that the service stopped, despite having AutoLog=true). Is there a way to have uncaught exceptions written straight to the log, even if they aren't in the original thread?

• VB6 code for Reading/Writing Windows Registry values

  - by Clay Nichols

  I'm looking for a good example of reading and writing to the Windows Registry using VB6. Yes, I know there are lots of mediocre examples. I spent an hour googling and testing. Some were incredibly complex, others had only some of the functions, and almost none of it had been vetted in any way (voted on). Since Stack Overflow is intended to the canonical location for answers to programming questions, it seems reasonable to post it here.

• Preventing threads from writing to the same file

  - by EpsilonVector

  I'm implementing an FTP-like protocol in Linux kernel 2.4 (homework), and I was under the impression that if a file is open for writing any subsequent attempt to open it by another thread should fail, until I actually tried it and discovered it goes through. How do I prevent this from happening? PS: I'm using open() to open the file.

• Workflow for reading and writing files

  - by AIR_PhillipSenn

  In Workflow for reading and writing files the authors use these two lines of code: var file = air.File.documentsDirectory; file = file.resolvePath("AIR Test/testFile.txt"); But I think that it's using one variable for two different meanings, isn't it? Wouldn't it be better to write them as: var myDocumentsDirectory = air.File.documentsDirectory; var myTestFile = myDocumentsDirectory.resolvePath("AIR Test/testFile.txt");
