It's perfectly valid for this set of data to be this large and the web service can be called either sync or async, but I'm wondering what people's thoughts are on the following:
1. If the connection is lost, the
entire resultset will have to be
regenerated and sent again. Is there
any way I can do any sort of
"resume" if the connection is lost
or reset?
2. Is sending a result set this large even appropriate? Would it be better to implement some sort of "paging" where the resultset is generated and stored on the server and the client can then download chunks of the resultset in smaller amounts and re-assemble the set at their end?

How much overhead is generated by using this method for file transfer? I assume the data looks something like this:
<?xml version="1.0" encoding="UTF-8" ?>
<bytes>
<byte>16</byte>
<byte>28</byte>
<byte>127</byte>
...
</bytes>
If this format is correct, the bytes must first be converted to UTF-8 characters. Each of these characters allocates 8 bytes. Are the bytes stored in base 10, hex, or binary characters? How much larger does the file appear as it is being sent due to the XML data and character encoding? Is there any compression built into web services?

In particular, different objects would ideally act the same, which would be very easily achieved with polymorphism. The problem I have with it is that inheritance implies the _is a_ relationship, rather than the _has a_ relationship. For example, several objects _have a_ damage counter, but to make this easy to use in an object list, polymorphism could be used - except that would imply an _is a_ relationship which wouldn't be true. (A person _is not_ a damage counter.)
The only solution I can think of is to have a member of the class return the proper object type when implicitly casted instead of relying on inheritance. **Would it be better to forgo the _is a_ / _has a_ ideal in exchange for ease of programming?** | inheritance | polymorphism | oop | null | null | null | open | Inheritance and Polymorphism - Ease of use vs Purity

First of all, the "browse" button looks different on every browser. Unlike the "submit" button on a form, you have to come up with some [hack-y](http://www.quirksmode.org/dom/inputfile.html) way to style it.
Secondly, there's no progress indicator showing you how much of the file has uploaded. You usually have to implement some kind of client-side way to disable multiple submits (e.g. change the submit button to a disabled button showing "Form submitting... please wait.") or flash a giant warning "DO NOT SUBMIT TWICE.'

You usually have to implement some kind of client-side way to disable multiple submits (e.g. change the submit button to a disabled button showing "Form submitting... please wait.") or flash a giant warning "DO NOT SUBMIT TWICE.'
Are there any good non-Flash or silly Java applet solutions to this? | 0 |

I am trying to adopt a test driven development style, so my goal is to unit test all parts of the app.
So, my question is: Is there a good way to unit test a timer based class?
The problem, as I see it, is that there is a big risk that the tests will take uncomfortably long to execute, since they must wait so and so long for the desired actions to happen. Especially if one want realistic data (seconds), and not use the minimal time resolution allowed by the framework (1 ms?). I am using a mock object for the action, to register the number of times the action was called, and so that the action takes practically no time.
Thanks

the ImportProgressEvent args carries a string message, a max int value for the progress bar and an current progress int value. The Windows form subcribes to the event:

Most of those settings are there to customize certain business rules, but there's also some other stuff in there.
The app contains objects that specifically do a certain task, e.g., a certain complicated calculation. Those non-UI objects are unit-tested, but also need access to lots of those global settings. The way we've implemented this right now, is by giving the objects properties that are filled by the Application Controller at runtime. When testing, we create the objects in the test and fill in values for testing (not from the database).
This works better, in any case much better than having all those objects need some global _Settings_ object --- that of course effectively makes unit testing impossible :) Disadvantage can be that you sometimes need to set a dozen of properties, or that you need to let those properties 'percolate' into sub-objects.
**So the general question is**: how do you provide access to global application settings in your projects, without the need for global variables, while still being able to unit test your code? This must be a problem that's been solved 100's of times...

I installed VS SP1 and played around with Entity Framework.
I created a schema from an existing database and tried some basic operations.
Most of it went well, except the database schema update.
I changed the database in every basic way:
- added a new table
- deleted a table
- added a new column to an existing table
- deleted a column from an existing table
- changed the type of an existing column
The first three went well, but the type change and the column deletion did not followed the database changes.

Let's say you have a maintenance plan with a task to check the database, something like this:
USE [MyDb]
GO
DBCC CHECKDB with no_infomsgs, all_errormsgs
If you go look in your logs after the task executes, you might see something like this:

Instead of checking MyDb, it checked master and msssqlsystemresource.

My workaround is to create a Sql Server Agent Job with this:

We have made several attempts at building unit tests around some of our key stored procedures (primarily testing the performance), but have found that setting up the test data for these tests is really hard.

In addition to this, the tests end up being really sensitive to change, and even the smallest change to a stored proc. or table requires a large amount of changes to the tests. So after many builds breaking due to these database tests failing intermittently, we’ve just had to pull them out of the build process.
So, the main part of my questions is: has anyone ever successfully written unit tests for their stored procedures?
The second part of my questions is whether unit testing would be/is easier with linq?
I was thinking that rather than having to set up tables of test data, you could simply create a collection of test objects, and test your linq code in a “linq to objects” situation? (I am a totally new to linq so don’t know if this would even work at all)

I've run across the usual suspects (indexus sharedcache, memcached), however, each has some limitations.
- **Indexus** - Very immature, stubbed session interface implementation. Its otherwise a great caching solution, though.
- **Memcached** - Little replication/failover support without going to a db backend.
Several SF.Net projects - All aborted in the early stages... nothing that appears to have any traction, and one which seems to have gone all commercial.
- **Microsoft Velocity** - Not OSS, but seems nice. Unfortunately, I didn't see where CTP1 supported failover, and there is no clear roadmap for this one. I fear that this one could fall off into the ether like many other MS dev projects.
I am fairly used to the Java world where it is kind of taken for granted that many solutions to problems such as this will be available from the FOSS world.
Are there any suitable alternatives available on the .Net world? | asp.net | clustering | failover | sessionreplication | null | null | open | FOSS ASP.Net Session Replication Solution?

Once I have my renamed files I need to add them to my project wiki page. This is a fairly repetitive manual task, so I guess I could script it but I don't know where to start.
The process is:
Got to appropriate page on the wiki
for each team member (DeveloperA, DeveloperB, DeveloperC)
{
for each of two files ('*_current.jpg', '*_lastweek.jpg')
{
Select 'Attach' link on page
Select the 'manage' link next to the file to be updated
Click 'Browse' button
Browse to the relevant file (which has the same name as the previous version)
Click 'Upload file' button
}
}
Not necessarily looking for the full solution as I'd like to give it a go myself.
Where to begin...? What language could I use to do this and how difficult would it be?

So, let's try to tackle the problem all three ways. How do you go from an arithmetic expression (e.g. in a string) such as "2 + (2)" to an expression tree using cascaded-if's, a table of function pointers, and/or polymorphism?
Feel free to tackle one, two, or all three.

I've drawn up most of the plans but am having a hard time figuring out a way to handle the auditing system.
Since it is being used internally only and you won't even be able to touch the db from outside the building we are not using a login system as the program will only be used once a user has already logged in to our internal network via Active Directory. Knowing this, we're using [a system to detect automatically the name of the Active Directory user][1] and with their permissions in one of the DB tables, deciding what they can or cannot do.
So the actual audit table will have 3 columns (this design may change but for this question it doesn't matter); who (Active Directory User), when (time of addition/deletion/edit), what (what was changed)
My question is how should I be handling this. Ideally I know I should be using a trigger so that it is impossible for the database to be updated without an audit being logged, however I don't know how I could grab the Active Directory User that way. An alternate would be to code it directly into the Access source so that whenever something changes I run an INSERT statement. Obviously that is flawed because if something happens to Access or the database is touched by something else then it will not log the audit.
Any advice, examples or articles that may help me would be greatly appreciated!

**WebClient**
Nice and easy but you do not get any notification that the asynchronous upload has completed, and the **UploadProgressChanged** event doesnt get called back with anything useful. The alternative is to convert your binary data to a string and use **UploadStringASync** because then at least you get a **UploadStringCompleted**, problem is you need a lot of ram for big files as its encoding all the data and uploading it in one go.
**HttpWebRequest**
Bit more complicated but still does what is needed, problem I am getting is that even though it is called on a background thread (supposedly), it still seems to be blocking my UI and the whole browser until the upload has completed which doesnt seem quite right.
Normal .net does have some appropriate WebClient methods for [OnUploadDataCompleted][1] and progress but these arent available in Silverlight .net ... big omission I think!
Does anyone have any solutions, I need to upload multiple binary files preferrably with a progress but I need to perform some actions when the files have completed their upload.
Look forward to some help with this.

Anyway, I'm not currently using prepared statements for querying, because I couldn't come up with a way to pass a variable number of arguments to the bind_params() or bind_result() methods.

Now, I've already thought of building an argument list and passing a string to eval(), but I don't like that solution very much--I'd rather just implement my own security checks and pass on statements.
Does anyone have any suggestions (or success stories) about how to get this done?

I know that this is often a highly debated topic, as far as whether or not returning DataTables is a good practice. Let's put that aside for a moment.
When I create a DataTable from scratch, as below, there are no problems whatsoever. The table is created, populated, and returned to the client, and all is well:
[DataContract]
public DataTable GetTbl()
{
DataTable tbl = new DataTable("testTbl");
for(int i=0;i<100;i++)
{
tbl.Columns.Add(i);
tbl.Rows.Add(new string[]{"testValue"});
}
return tbl;
}
However, as soon as I go out and hit the database to create the table, as below, I get a CommunicationException "The underlying connection was closed: The connection was closed unexpectedly."
[DataContract]
public DataTable GetTbl()
{
DataTable tbl = new DataTable("testTbl");
//populate table with sql query
return tbl;
}
The table is being populated correctly on the server side. It is significantly smaller than the test table that I looped through and returned, and the query is small and fast - there is no issue here with timeouts or large data transfer. The same exact functions and DataContracts/ServiceContracts/BehaviorContracts are being used.
Why would the way that the table is being populated have any bearing on the table returning successfully?? | .net | webservices | wcf | datatable | null | null | open | .Net - Returning DataTables in WCF

For example: I have a bunch of data rows and want to change the "category" field on each -- maybe a dropdown, maybe a link, maybe the user types it in.
In Rails, I'd iterate over the rows to build a table, and would have a form for each row. The form would have an input box or dropdown, and submit the data to a controller like "/item/edit/15?category=foo" where 15 was the itemID and the new category was "foo".
I'm new to the ASP.NET model and am not sure of the "right" way to do this -- just the simplest way to get back the new data & save it off. Would I make a custom control and append it to each row? Any help appreciated. | asp.net | null | null | null | null | null | open | Best way to custom edit records in ASP.NET?
