One viewpoint is that the data layer should be aware of business objects (our own classes that represent an entity), and be able to work with that object natively.
The opposing viewpoint is that the data layer should be object-agnostic, and purely handle simple data types (strings, bools, dates, etc.)
I can see that both approaches may be valid, but my own viewpoint is that I prefer the former. That way, if the data storage medium changes, the business layer doesn't (necessarily) have to change to accommodate the new data layer. It would therefore be a trivial thing to change from a SQL data store to a serialized xml filesystem store.
My colleague's point of view is that the data layer shouldn't have to know about object definitions, and that as long as the data is passed about appropriately, that is enough.
Now, I know that this is one of those questions that has the potential to start a religious war, but I'd appreciate any feedback from the community on how you approach such things.
TIA

Say that I have a view which can accept drag and drop, but only in certain areas. Once the user drags over one of these areas I call <code>DragManager.acceptDrag(this)</code> (from a <code>DragEvent.DRAG_OVER</code> handler), but if the user then moves out of this area I'd like to change the status of the drag to not accepted and show the <code>DragManager.NONE</code> feedback. However, neither calling <code>DragManager.acceptDrag(null)</code> nor <code>DragManager.showFeedback(DragManager.NONE)</code> seems to have any effect. Once I've accepted the drag an set the feedback type I can't seem to change it.
Just to make it clear: the areas where the user should be able to drop are not components or even display objects, in fact they are just ranges in the text of a text field (like the selection). Had they been components of their own I could have solved it by making each of them accept drag events individually. I guess I could create proxy components that float over the text to emulate it, but I'd rather not if it isn't necessary. | flex | dragdrop | null | null | null | null | open | How can I "unaccept" a drag in Flex?

Our codebase contains ALOT of legacy/archaic code which must be kept operational. Some of this code is older than me (originally written in the late 70s) and some members of our team are still on Visual Studio 6.
However, a conclusion has thankfully been reached internally that our product is looking somewhat antiquated compared to our competitors', and that something needs to be done.
I am currently working on a new area of the UI which is quite separate from the rest of the product. I have therefore been given the chance to try out 'new' technology stacks as a sort of proving ground before the long process of moving over the rest of the UI begins.
I have been using C# with Windows Forms and the .net framework for a while in my spare time and enjoy it, but am somewhat worried about the headaches caused by interop. While this particular branch of the UI won't require much interop with the legacy C++ codebase, I can forsee this becoming an issue in the future.
The alternative is just to continue with MFC, but try and take advantage of the new feature pack that shipped with VS2008. This I guess is the easiest option, but I worry about longevity and not taking advantage of the goodness that is .net...
So, which do I pick? We're a small team so my recommendation will quite probably be accepted as a future direction for our development - I want to get it right.
Is MFC dead? Is C#/Winforms the way forward? Is there anything else I'm totally missing? Help greatly appreciated!

I know this question seems simple - and I'm sure there's a simple answer, but I've been spinning my wheels for some time on this one. I am dealing with a legacy db which really can't be altered structurally. I have a details table which lists payment plans that have been accepted by a customer. Each payment plan has an ID which links back to a reference table to get the plan's terms, conditions, etc. In my object model, I have an AcceptedPlan class, and a Plan class. Originally, I used a many-to-one relationship from the detail table back to the ref table to model this relationship in NHibernate. I also created a one-to-many relationship going in the opposite direction from the Plan class over to the AcceptedPlan class. This was fine while I was simply reading data. I could go to my Plan object, which was a property of my AcceptedPlan class to read the plan's details. My problem arose when I had to start inserting new rows to the details table. From my reading, it seems the only way to create a new child object is to add it to the parent object and then save the session. But I don't want to have to create a new parent Plan object every time I want to create a new detail record. This seems like unnecessary overhead.

To make a really long story short I am getting XML from a webservice of serialized objects. I have a page limit of how many things can be on a page. I've taken a data grid and made it page, sort across pages, and handle some basic filtering.
In regards to paging I'm using a Dictionary keyed on the page and storing the XML for that page. This way whenever a user comes back to a page that I've saved into this dictionary I can grab the XML from local memory instead of hitting the webservice. Basically, I'm caching the data retrieved from each call to the webservice for a page of data.
There are several things that can expire my cache. Filtering and sorting are the main reason. However, a user may edit a row of data in the grid by opening an editor. The data they edit could cause the data displayed in the row to be stale. I could easily go to the webservice and get the whole page of data, but since the page size is set at runtime I could be looking at a large amount of records to retrieve.
So let me now get to the heart of the issue that I am experiencing. In order to prevent getting the whole page of data back I make a call to the webservice asking for the completely updated record (the editor handles saving its data).
Since I'm using custom objects I need to serialize them on the server to XML (this is handled already for other portions of our software). All data is handled through XML in e4x. The cache in the Dictionary is stored as an XMLList.
Now let me show you my code...
var idOfReplacee:String = this._WebService.GetSingleModelXml.lastResult.*[0].*[0].@Id;
var xmlToReplace:XMLList = this._DataPages[this._Options.PageIndex].Data.(@Id == idOfReplacee);
if(xmlToReplace.length() > 0)
{
delete (this._DataPages[this._Options.PageIndex].Data.(@Id == idOfReplacee)[0]);
this._DataPages[this._Options.PageIndex].Data += this._WebService.GetSingleModelXml.lastResult.*[0].*[0];
}
Basically, I get the id of the node I want to replace. Then I find it in the cache's Data property (XMLList). I make sure it exists since the filter on the second line returns the XMLList.
The problem I have is with the delete line. I cannot make that line delete that node from the list. The line following the delete line works. I've added the node to the list.
How do I replace or delete that node (meaning the node that I find from the filter statement out of the .Data property of the cache)???

I need to be able to generate a deep clone of this object - so I write a Clone() method, and implement it with a simple BinaryFormatter serialize/deserialize - or perhaps I do the deep clone using some other technique which is more error prone and I'd like to make sure is tested.
OK, so now (ok, I should have done it first) I'd like write tests which cover the cloning. All the members of the class are private, and my architecture is so good (!) that I haven't needed to write hundreds of public properties or other accessors. The class isn't IComparable or IEquatable, because that's not needed by the application. My unit tests are in a separate assembly to the production code.
What approaches do people take to testing that the cloned object is a good copy? Do you write (or *rewrite* once you discover the need for the clone) all your unit tests for the class so that they can be invoked with *either* a 'virgin' object *or* with a clone of it? How would you test if part of the cloning wasn't deep enough - as this is just the kind of problem which can give hideous-to-find bugs later?

The class isn't IComparable or IEquatable, because that's not needed by the application. My unit tests are in a separate assembly to the production code.
What approaches do people take to testing that the cloned object is a good copy? Do you write (or *rewrite* once you discover the need for the clone) all your unit tests for the class so that they can be invoked with *either* a 'virgin' object *or* with a clone of it? How would you test if part of the cloning wasn't deep enough - as this is just the kind of problem which can give hideous-to-find bugs later?

I'm wondering what people's opinions are on specialists vs. generalists. Should you build a team of people who can pretty much do it all (jack-of-all-trades), or should each person be totaly focused on one aspect of software engineering, leaving the big picture to the development lead?
I tend to prefer generalists, because it gives you a lot more flexibility when things change, and developers who understand the big picture, how every part of an application interacts with every other part, tend to waste less time designing things that just won't fit.
The counter-argument to that, of course, is that a generalist doesn't have time to truly master all the intricate details of each technology, and therefore will be less effective than a specialist. | team | null | null | null | null | 02/07/2012 19:52:26 | off topic | What's the ideal development team composition?

I have developed a code-generator that takes our python interface to our C++ code (generated via SWIG) and generates code needed to expose this as WebServices. When I developed this code I did it using TDD, but I've found my tests to be brittle as hell. Because each test essentially wanted to verify that for a given bit of input code (which happens to be a C++ header) I'd get a given bit of outputted code I wrote a small engine that reads test definitions from XML input files and generates test cases from these expectations.
The problem is I dread going in to modify the code at all. That and the fact that the unit tests themselves are a: complex, and b: brittle.
So I'm trying to think of alternative approaches to this problem, and it strikes me I'm perhaps tackling it the wrong way. Maybe I need to focus more on the outcome, IE: does the code I generate actually run and do what I want it to, rather than, does the code look the way I want it to.

{
}
private Data[] m_myData;
private DataTime m_cacheTime;
public Data[] GetData()

{
// Do SQL to get data
m_myData = data;
m_cacheTime = DateTime.Now;
return m_myData;
}
else
{
return m_myData;
}
}
}
So the values are stored for a while in a singleton, and when the time expires, the values are renewed. If time has not expired, and a request for the data is done, the stored values in the field are returned.

I wish to design a workflow host environment that has high availability - a minimum of 2 WF runtime hosts on separate hardware both pointing to the same persistance or tracking SQL database.
I am looking for a pattern whereby I can asynchronously create new workflow instances based on some external event (i.e. some piece of data is updated in DB by a different application). For each event I need to create exactly one workflow instance and doesn't matter which host that instance is created on. There is also some flexibility regarding the duration of time between the event and when the workflow instance is actually created.
One solution I am considering is having a WCF interface on the WF hosts and placing them behind some sort of load balancer. It would then be up to whatever part of the system that is firing the "event" to make the WCF call.
I'm not really happy with this because if both\all WF hosts are down, or otherwise unavailable, the event could be "lost". Also, I won't be able manage load the way I would like to. I envisage a situation where there may be lots of events in a small period of time, but it's perfectly acceptable to handle those events some time later.
So I reckon I need to persist the events somehow and decouple the event creation from the event handling.
Is putting these events into MSMQ, or a simple event table in SQL Server, and having the WF host just poll the queue periodically a viable solution? Polling seems to be a such a dirty word though...
Would NServiceBus and durable messaging be useful here?
Any insights would be much appreciated.

##Current Result
Now, when I double click the the control when it is on a ASPX page, the following is created:

{
}

There are two or more object collections of different types. You want to combine them into a single sortable and filterable collection (withing having to manually implement sort or filter).
One of the approaches I've considered is to create a new object collection with only a few core properties, including the ones that I would want the collection sorted on, and an object instance of each type.
class MyCompositeObject
{
enum ObjectType;
DateTime CreatedDate;
string SomeAttribute;
myObjectType1 Obj1;
myObjectType2 Obj2;
{
class MyCompositeObjects : List<MyCompositeObject> { }
And then loop through my two object collectiosn to build the new composite collection. Obviously this is a bit of a brute force method, but it would work. I'd get all the default view sorting and filtering behavior on my new composite object collection, and I'd be able to put a data template on it to display my list items properly depending on which type is actually stored in that composite item.
What suggestions are there for doing this in a more elegant way? | c# | wpf | data-binding | collections | null | null | open | WPF - Sorting a composite collection

>> <foo xmlns="uri" />
It appears as though some of the XPATH processor libraries won't recognize //foo because of the namespace whereas others will. The option my team has thought about is to add a namespace prefix using regular expressions to the XPATH (you can add a namespace prefix via XmlNameTable) but this seems brittle since XPATH is such a flexible language when it comes to node tests.
Is there a standard that applies to this?
My approach is a bit hackish but it seems to work fine; I remove the xmlns declaration with a search/replace and then apply xpaths.
>string readyForXpath = Regex.Replace( xmldocument, "xmlns=\".+\"", String.Empty );

Let's see your implementations (in your language of choice, of course) of a function which returns a human readable String representation of a specified Integer. For example:
<ul>
<li>humanReadable(1) returns "one".
<li>humanReadable(53) returns "fifty-three".
<li>humanReadable(723603) returns "seven hundred and twenty-three thousand, six hundred and three".
<li>humanReadable(1456376562) returns "one billion, four hundred and fifty-six million, three hundred and seventy-six thousand, five hundred and sixty-two".
</ul>
Bonus points for particularly clever/elegant solutions!
It might seem like a pointless exercise, but there are number of real world applications for this kind of algorithm (although supporting numbers as high as a billion may be overkill :-)

I think a similar pattern could be used for taking an XML or tab-delimited file and parse it into their representative objects.
A common data structure would include:
> (Header) (DataElement1) (DataElement1SubData1) (DataElement1SubData2)(DataElement2) (DataElement2SubData1) (DataElement2SubData2) (EOF)
I think a good design would include a way to change out the parsing definition based on the file type or some defined metadata included in the header. So a [Factory Pattern][1] would be part of the overall design for the Parser part.

I'm in the middle of designing an app that does something like portfolio management. The design I have so far is
* Problem: a problem that needs to be solved
* Solution: a proposed solution to one or more problems
* Relationship: a relationship among two problems, two solutions, or a problem and a solution. Further broken down into:
* Parent-child - some sort of categorization / tree hierarchy
* Overlap - the degree to which two solutions or two problems really address the same concept
* Addresses - the degree to which a problem addresses a solution
My question is about the temporal nature of these things. Problems crop up, then fade. Solutions have an expected resolution date, but that might be modified as they are developed. The degree of a relationship might change over time as problems and solutions evolve.

Since many hosting companies offer a single database with their hosting plans (with additional databases costing extra) it is very useful for your users when your database objects (tables, views, constraints, and stored procedures) have a common prefix. It is typical for applications aware of database scarcity to have a hard-coded table prefix. I want more, however. Specifically, I'd like to have a table prefix that users can designate—say in the web.config file (with an appropriate default, of course).
Since I hate coding [CRUD](http://en.wikipedia.org/wiki/Create%2C_read%2C_update_and_delete) operations by hand, I prefer to work through a competent OR/M and have used (and enjoyed) LINQ to SQL, Subsonic, and ADO.Net.

The best I have been able to come up with so far is using LINQ to SQL with an external mapping file that I'd have to update somehow based on an as-yet hypothetical web.config setting.
Anyone have a better solution? I tried to make it happen in Entity Framework, but that turned into a mess quickly. (Due to my unfamiliarity with EF? Possibly.) How about SubSonic?

Previously, the apps on this server were not hit very often, but we're rolling out a high demand application. So, what is the best practice for publishing to a live web server?
1. Is it best to wait until the middle
of the night when people won't be on
it (Yes, I can pretty much rely on
that -- it's an intranet and
therefore will have times of
non-use)
2. Publish when new updates are made to
the trunk (dependent on build
success of course)
3. If 2 is true, then that seems bad if someone is using that specific page or DLL and it gets overwritten.
...I'm sure there are lots of great places for this kind of thing, but I didn't use the right google search terms.
