• zlib memory usage / performance. With 500kb of data.

  - by unixman83

  Is zLib Worth it? Are there other better suited compressors? I am using an embedded system. Frequently, I have only 3MB of RAM or less available to my application. So I am considering using zlib to compress my buffers. I am concerned about overhead however. The buffer's average size will be 30kb. This probably won't get compressed by zlib. Anyone know of a good compressor for extremely limited memory environments? However, I will experience occasional maximum buffer sizes of 700kb, with 500kb much more common. Is zlib worth it in this case? Or is the overhead too much to justify? My sole considerations for compression are RAM overhead of algorithm and performance at least as good as zlib.

• Excel VBA: importing CSV with dates as dd/mm/yyyy

  - by Michael Smith

  ello I understand this is a fairly common problem, but I'm yet to find a reliable solution. I have data in a csv file with the first column formatted dd/mm/yyyy. When I open it with Workbooks.OpenText it defaults to mm/dd/yyyy until it figures out that what it thinks is the month exceeds 12, then reverts to dd/mm/yyyy. This is my test code, which tries to force it as xlDMYFormat, and I've also tried the text format. I understand this problem only applies to *.csv files, not *.txt, but that isn't an acceptable solution. Option Base 1 Sub TestImport() Filename = "test.csv" Dim ColumnArray(1 To 1, 1 To 2) ColumnsDesired = Array(1) DataTypeArray = Array(xlDMYFormat) ' populate the array for fieldinfo For x = LBound(ColumnsDesired) To UBound(ColumnsDesired) ColumnArray(x, 1) = ColumnsDesired(x) ColumnArray(x, 2) = DataTypeArray(x) Next x Workbooks.OpenText Filename:=Filename, DataType:=xlDelimited, Comma:=True, FieldInfo:=ColumnArray End Sub test.csv contains: Date 11/03/2010 12/03/2010 13/03/2010 14/03/2010 15/03/2010 16/03/2010 17/03/2010 Thanks Michael

• in which namespace / package to put exceptions

  - by Fabiano

  Hi What is the common or best practice to structure the location of your exception classes? Let's say you have the packages/namespaces myproject.person (models and DAOs for persons) and myproject.order (models and DAOs for orders) and the exceptions PersonException and OrderException. Should I put the exceptions in their corresponding packages or in a separate package for exceptions (e.g. myproject.exceptions)? The first approach seems more reasonable (because it's sorted by functionality). But there the question arises where you should put exceptions that are related to both? e.g. a ConstraintViolationException Thanks

• JPA @TableGenerator shared between multiple entities

  - by Mauricio

  Hi Guys, I have a 'dog' Entitiy with an @Id and a @TableGenerator ... @TableGenerator(table = "seq", name = "dog_gen", pkColumnName = "seq_name", valueColumnName="seq_val") @Id @GeneratedValue(strategy = GenerationType.TABLE, generator = "dog_gen") private Long id; ... Is there a way to reuse the same table generator (dog_gen) in other entity? I want to keep the same id sequence in two independent Entities, say dog=1, dog=2, dog=3, cat=4, cat=5, dog=6 and so on... Both entities don't share a common superclass to implement some kind of inheritance with the id property. If I add the @GeneratedValue( generator="dog_gen") on my cat entity, omitting the @TableGenerator declaration throws an Exception saying it can't find the generator when starting the context. Caused by: org.hibernate.AnnotationException: Unknown Id.generator: dog_gen at org.hibernate.cfg.BinderHelper.makeIdGenerator(BinderHelper.java:413) at org.hibernate.cfg.AnnotationBinder.bindId(AnnotationBinder.java:1795) at org.hibernate.cfg.AnnotationBinder.processElementAnnotations(AnnotationBinder.java:1229) at org.hibernate.cfg.AnnotationBinder.bindClass(AnnotationBinder.java:733) at org.hibernate.cfg.AnnotationConfiguration.processArtifactsOfType(AnnotationConfiguration.java:498) at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:277)

• Higher than high-level web frameworks or CMS's?

  - by Ben

  I'm looking for options that allow very high-level web site development with these special characteristics: not requiring the user to program in a complex programming language not requiring the user to use GUI-like administration areas allow the user to "program" in a lightweight markup language The last point is not only about look and structure of the output but also about creating simple dynamic output. For example: listing pages fetching the content of other pages doing a site search and displaying its output dynamically show or hide parts of the page depending on login status Of course, I am not expecting a solution that provides the same possibilities like a Ruby, Python or PHP web framework. Rather I am looking for support of the "basics" that are common for web sites. Until now, I have found only one piece of software that fulfills these requirements but while it's free, it's not open source: BoltWire at http://www.boltwire.com/. Being open source is required.

• How to determine the maximum integer the model can handle?

  - by John Mee

  "What is the biggest integer the model field that this application instance can handle?" We have sys.maxint, but I'm looking for the database+model instance. We have the IntegerField, the SmallIntegerField, the PositiveSmallIntegerField, and a couple of others beside. They could all vary between each other and each database type. I found the "IntegerRangeField" custom field example here on stackoverflow. Might have to use that, and guess the lowest common denominator? Or rethink the design I suppose. Is there an easy way to work out the biggest integer an IntegerField, or its variants, can cope with?

• Javascript top variable in IE8

  - by Jim Rootham

  I am trying to reference a javascript function in a .js file loaded in my main page from an iframe using the 'top' variable. It works in FF, Safari, and IE6 but not in IE8. The snippet is (assigned to onmouseover): top.set_image(this, 'images/login_h.png') Where set_image is my function. The error is "Object does not support this function" Also, I have been looking for the definition of top. I can't find it in the ECMAScript specification or the w3schools site and Google is unhelpful (who'da thunk top was a common word?).

• Cannot Debug Visual Basic 6 ActiveX Component On 64-bit OS

  - by Humanier

  Hi, The situation might sound a bit weird but I have to play with what I have. There's a Win2003 64-bit server OS and a legacy application written using Visual Studio 6. The app consists of two parts: ActiveX components written in VB6 and C++ code which uses them. I need to debug the components' code. I installed Visual Studio 6 on the server and I'm able to step into the component's code. Then I got following situation: 1) C++ code works until it needs to instantiate component A. 2) At this step we switch to VB6 and start debugging Component's A. 3) In the very beginning component A creates an instance of a class C exposed by component B. At this step VB6 debugger shows error message with title "OLEDB32.DLL" and following text: "Failed to load resource DLL C:\Program Files (x86)\Common Files\System\Ole DB\OLEDB32R.DLL" Additional information: The last step in initialization of the class C is opening an ADO connection to SQL server using OLEDB provider. I'd appreciate any ideas on how resolve this problem. Thanks in advance.

• Concerns about reading a file in Flash 10

  - by user246114

  Hi, I'd like to read an xml file on a user's machine (which can be kind of large). There's no point in me sending the file to my server as I can do all the work I need on the file right on the client's machine. Not sure if this is a good fit though, was wondering if anyone can answer these questions before I dive in: I see at adobe's website that Flash 10 has like 94% penetration, is this true, I thought it was just released not too long ago? After opening the xml file in flash, is it possible to just throw it to a javascript function on my same page for further processing? I'd like to go into flash world for as short a time as possible. Is it at all common to use flash for file upload stuff? I heard aol/flickr are? I would need to buy flash in order to do this right, they don't have a free ide/compiler yet? Thanks

• How to read and modify the colorspace of an image in c#

  - by Matthias

  I'm loading a Bitmap from a jpg file. If the image is not 24bit RGB, I'd like to convert it. The conversion should be fairly fast. The images I'm loading are up to huge (9000*9000 pixel with a compressed size of 40-50MB). How can this be done? Btw: I don't want to use any external libraries if possible. But if you know of an open source utility class performing the most common imaging tasks, I'd be happy to hear about it. Thanks in advance.

• Using SharePoint user profiles to build a company phone directory

  - by Jonathan

  I'm working on a Sharepoint 2007 (MOSS Std) intranet implementation right now, and one of the things we'd like to do is replace the manually-maintained phone directory with the profile information we're importing from AD. People search is great, but I want to have a big page with all the names and phone numbers of the 150 or so people that work at the company (which means using the People Search webpart with a query hard-coded to return everyone won't work). A few quick searches haven't turned up anything, but this seems like a really common request. Can anyone help me out? I'm not opposed to buying a reasonably-priced webpart to solve this or writing some custom code, but both seem like they shouldn't be required for such a simple request.

• where should we send notification for updating many views?

  - by Thanh-Cong Vo

  Hi all, I want to ask about software design. I have a task, the view controller handles UI event for calling a model manger to perform that task. After finishing, the model manager will callback to update the view. There have also other views who care about that task, and also want to update its own view when that task is finished. So I register a Notification for that task in each views. The problem is defining where should I send Notification, in Model manager or in the View who handles event and receives the callback from Model manager? What is better design? Shoud the model care about send this "common" task, or shoud the view? Thanks

• How to keep views free of authorization logic in mvc?

  - by David Lay

  I have a view to display a list of items. The user can edit, delete or create new items, but according to their authorizations they may or may not be allowed to do some of this actions. I have the requirement to display only the actions which the current user is allowed to do, but I don't want to clutter the views with authorization if-else's Despise of being a very common requirement, I can't find a real satisfactory way of doing it. My best approach so far is to provide an overload to the Html.ActionLink extension method that takes the permission to ask for, but there are going to be more complex scenarios, like hiding entire blocks of html or switching a textbox for a label+hidden. Is there a better way to do this?

• Windows Azure Platform, latest version?

  - by Vimvq1987

  I searched through internet but found nothing. The whitepapers of Windows Azure Platform say something like that: In its first release, the maximum size of a single database in SQL Azure Database is 10 gigabytes A few things are omitted in the technology’s first release, however, such as the SQL Common Language Runtime (CLR) and support for spatial data. (Microsoft says that both will be available in a future version.) I want to know that Microsoft had updated Windows Azure Platform and removed these limits or not? I decided to post this question here instead of Serverfault.com because it's more relative to programming than administration. Thank you

• What is the difference between Java RMI and JMS?

  - by Sanoj

  When designing an distributed application in Java there seams to be a few technologies that address the same kind of problem. I have briefly read about Java Remote Method Invocation and Java Message Service, but it is hard to really see the difference. Java RMI seams to be more tightly coupled than JMS because JMS use asynchronous communication, but otherwise I don't see any big differences. What is the difference between them? Is one of them newer than the other one? Which one is more common/popular in enterprises? What advantages do they have over eachother? When is one preferred over the other? Do they differ much in how difficult they are to implement? I also think that Web Services and CORBA address the same problem.

• ruby syntactic sugar: dealing with nils..

  - by luca

  probably asked already but I couldn't find it.. here are 2 common situation (for me while programming rails..) that are frustrating to write in ruby: "a string".match(/abc(.+)abc/)[1] in this case I get an error because the string doesn't match, therefore the [] operator is called upon nil. What I'd like to find is a nicer alternative to the following: temp="a string".match(/abc(.+)abc/); temp.nil? ? nil : temp[1] in brief, if it didn't match simply return nil without the error The second situation is this one: var = something.very.long.and.tedious.to.write var = something.other if var.nil? In this case I want to assign something to var only if it's not nil, in case it's nil I'll assign something.other.. Any suggestion? Thanks!

• Kendo UI, searchable Combobox

  - by user2083524

  I am using the free Kendo UI Core Framework. I am looking for a searchable Combobox that fires the sql after inserting, for example, 2 letters. Behind my Listbox there are more than 10000 items and now it takes too much time when I load or refresh the page. Is it possible to trigger the sql query only by user input like the autocomplete widget do? My code is: <link href="test/styles/kendo.common.min.css" rel="stylesheet" /> <link href="test/styles/kendo.default.min.css" rel="stylesheet" /> <script src="test/js/jquery.min.js"></script> <script src="test/js/kendo.ui.core.min.js"></script> <script> $(document).ready(function() { var objekte = $("#objekte").kendoComboBox({ placeholder: "Objekt auswählen", dataTextField: "kurzname", dataValueField: "objekt_id", minLength: 2, delay: 0, dataSource: new kendo.data.DataSource({ transport: { read: "test/objects.php" }, schema: { data: "data" } }), }).data("kendoComboBox"); </script>

• Output Path property issue on build server

  I am working in the .NET 3.5 framework. I have a project that builds fine locally. I can build it on our build server when the source files are posted there. However when I am running the build process through Visual Studio 2010 I get a warning that says "C:\WINDOWS\Microsoft.NET\Framework64\v3.5\Microsoft.Common.targets: The OutputPath property is not set for this project. Please check to make sure that you have specified a valid Configuration/Platform combination. Configuration='DEV' Platform='Any CPU'" Any suggestions anyone has or if you need additional information please let me know. I have been struggling with this for a couple of days now. Thanks in advance for your help. Jay Clarke

• Silverlight, dealing with Async calls

  - by Billy

  Hi there, I have some code as below: foreach (var position in mAllPositions) { DoAsyncCall(position); } //I want to execute code here after each Async call has finished So how can I do the above? I could do something like: while (count < mAllPositions.Count) { //Run my code here } and increment count after each Async call is made ... but this doesn't seem like a good way of doing it Any advice? Is there some design pattern for the above problem as i'm sure it's a common scenario?

• Open source iPhone components? Reusable views, controllers, buttons, table cells, etc?

  - by Ian Terrell

  Are there any repositories around for open sourced iPhone components? For instance, I have found myself needing to create several new types of table cells to mimic some of Apple's existing functionality (for instance, all the different types of table cells present in the Settings application). I can't imagine I'm alone here. Where do you go to find open sourced reusable components, or do you just write and hoard your own? Update: I know there are open source full projects around (see this question), but rummaging through them and picking and choosing still leads to significant duplication of effort. Update 2: Here are some libraries that I've found (or have come into existence) since asking this question: Three20 -- Custom UI classes used in the Facebook application CocoaHelpers -- Extensions to common classes MBProgressHUD -- Replacement for the undocumented UIProgressHUD

• Most used .NET namespace

  - by Michael Prewecki

  What is your most commonly used namespace in .NET. I know it will vary greatly based upon the types of projects you develop but the stack overflow audience should provide a fairly decent sample set for the types of .NET projects being developed. I'm simply interest in the name of the namespace (one namespace per answer and no one person should have more than one answer, if someone else has the same answer as you then just upvote their answer). Try to be as specific as possible (so answering System, isn't helpful). I'm after this information to help new developers focus their attention on the most common .NET namespaces...there are after all thousands of them! To start off mine is almost certainly System.Collections.Generic, I use lists of things everywhere.

• Is `hg pull --rebase` analogous to `svn update`?

  - by allyourcode

  This question assumes there's a "blessed" central repository that members of a team clone from push to when they have contributions that they want other team members to see pull from when they want to see other people's contributions. etc. If so, I would assume hg update is not analogous to svn update (why would there be two commands that do exactly the same thing?). From what I can gather, hg update more like svn revert. Is that correct? Update: My understanding of rebase is largely based on the "A common case" section on this page: http://mercurial.selenic.com/wiki/RebaseProject

• Dice face value recognition

  - by Jakob Gade

  I’m trying to build a simple application that will recognize the values of two 6-sided dice. I’m looking for some general pointers, or maybe even an open source project. The two dice will be black and white, with white and black pips respectively. Their distance to the camera will always be the same, but their position on the playing surface will be random. (not the best example, the surface will be a different color and the shadows will be gone) I have no prior experience with developing this kind of recognition software, but I would assume the trick is to first isolate the faces by searching for the square profile with a dominating white or black color (the rest of the image, i.e. the table/playing surface, will in distinctly different colors), and then isolate the pips for the count. Shadows will be eliminated by top down lighting. I’m hoping the described scenario is so simple (read: common) it may even be used as an “introductory exercise” for developers working on OCR technologies or similar computer vision challenges.
