But I've never done any .NET, VB, or C# stuff. What exactly does "managed" code mean? [Wikipedia][1] describes it simply as "code that executes under the management of a virtual machine", and it specifically says that Java is (usually) managed code, so why does the term only seem to apply to C# / .NET? Can you compile C# into a .exe that contains the VM as well, or do you have to package it up and give it to another .exe (a la java)?
In a similar vein, is .NET a *language* or a *framework*, and what exactly does "framework" mean here?
OK, so that's more than one question, but for someone who's been in the industry as long as I have, I'm feeling rather N00B-ish right now...

| NAME | CLUB | STATUS | SCORE |
| Fred | a | Gent | 145 |
| Bert | a | Gent | 150 |
| Harry | a | Gent | 195 |
| Jim | a | Gent | 150 |
| Clare | a | Lady | 99 |
| Simon | a | Junior | 130 |
| John | b | Junior | 130 |
:
:
| Henry | z | Gent | 200 |
I need to convert this table into a list of the "Top Ten" teams. The rules are
- Each team score is taken from the sum of four members of that club.
- These totals should be of the best four scores except...
- Each team must consist of at least one Junior or Lady
For example in the table above the team score for club A would be 625 **not** 640 as you would take the scores for Harry(190), Bert(150), Jim(150), and Simon(130). You could not take Fred's(145) score as that would give you only Gents.
My question is, can this be done easily as a series of Excel formula, or will I need to resort to using something more procedural?
Ideally the solution needs to be automatic in the team selections, I don't want to have to create separate hand crafted formula for each team. I also will not necessarily have a neatly ordered list of each clubs members. Although I could probably generate the list via an extra calculation sheet.
Thanks

So, for example, some of the applications I work with use settings which we access with:
string blah = AppLib.Properties.Settings.Default.TemplatePath;
Now, this option seems cool because the members are stongly typed, and I won't be able to type in a property name that doesn't exist in the Visual Studio 2005 IDE. We end up with lines like this in the App.Config of a command-line executable project:
<connectionStrings>
<add name="AppConnectionString" connectionString="XXXX" />
<add name="AppLib.Properties.Settings.AppConnectionString" connectionString="XXXX" />
</connectionStrings>
(If we don't have the second setting, someone releasing a debug dll to the live box could have built with the debug connection string embedded in it - eek)
We also have settings accessed like this:
string blah = System.Configuration.ConfigurationManager.AppSettings["TemplatePath_PDF"];
Now, these seem cool because we can access the setting from the dll code, or the exe / aspx code, and all we need in the Web or App.config is:
<appSettings>
<add key="TemplatePath_PDF" value="xxx"/>
</appSettings>
However, the value of course may not be set in the config files, or the string name may be mistyped, and so we have a different set of problems.
So... if my understanding is correct, the former methods give strong typing but bad sharing of values between the dll and other projects. The latter provides better sharing, but weaker typing.
I feel like I must be missing something. For the moment, I'm not even concerned with the application being able to write-back values to the configuration files, encryption or anything like that. Also, I had decided that the best way to store any non-connection strings was in the DB... and then the very next thing that I have to do is store phone numbers to text people in case of DB connection issues, so they must be stored outside the DB!

Cannot convert System.Web.HttpContext to ...IWebBase via a reference conversion, boxing conversion, unboxing conversion, wrapping conversion or null type conversion. | c# | asp.net | null | null | null | null | open | Finding System.Web.UI.Page from HttpContext
===
This is actually a two part question. First,does the HttpContext.Current correspond to the current System.UI.Page object?
And the second question, which is probably related to the first, is why can't I use the following to see if the current page implements an interface:
private IWebBase FindWebBase()
{
if (HttpContext.Current as IWebBase != null)
{
return (IWebBase)HttpContext.Current.;
}
throw new NotImplementedException("Crawling for IWebBase not implemented yet");
}
The general context is that some controls need to know whether they are executing as a SharePoint webpart, or as part of an Asp.Net framework.

Is this because I'm applying the tool in an invalid Context, or is it deeper than that?
When can/should you go whole hog with the ORM approach?
Any insight would be greatly appreciated.
----------
A little of background:
In my environment I have about 50 client computers and 1 reasonably powerful SQL Server.
I have a desktop application in which all 50 clients are accessing the data at all times.
The project's Data Model has gone through a number of reorganizations for various reasons including clarity, efficiency, etc.
My Data Model's history
0. JDBC calls directly
1. DAO + POJO without relations between Pojos (basically wrapping the JDBC).
2. Added Relations between POJOs implementing Lazy Loading, but just hiding the inter-DAO calls
3. Jumped onto the Hibernate bandwagon after seeing how "simple" it made data access (it made inter POJO relations trivial) and because it could decrease the number of round trips to the database when working with many related entities.
4. Since it was a desktop application keeping Sessions open long term was a nightmare so it ended up causing a whole lot of issues
5. Stepped back to a partial DAO/Hibernate approach that allows me to make direct JDBC calls behind the DAO curtain while at the same time using Hibernate.

If I chose B as my starting record and E as my ending record, I would want to find all paths through the record connections that would connect record B to record E.
<pre>
All paths connecting B to E:
B->E
B->F->E
B->F->C->E
B->A->C->E
B->A->C->F->E
</pre>
This is an example, in practice I may have sets containing hundreds of thousands of records. | 0 |

I don’t want to check conditions in the loop. I don’t really want to add the first or the last string before/after the loop (I guess this is maybe the best way?).

I have no experience with Business Process Management tools use or implementation. (The closest thing I have used is BizTalk server, but I know that it is not really a full BPM product, but a document based integration platform with some process orchestration features).
Recently, several of our clients have been asking for BPM-based development projects, and most of the time I discover that some BPM vendor has been giving them some of those 'look how amazing is my product' demos, where they show 'how easily' you can modify your business process flow just by 'dragging and dropping' shapes around and those kind of things.
Obviously, vendors don't say anything about **how you first need to have running your well designed processes on the BPM so you can actually make that kind of magic happen**.
My clients suddenly see a new light thinking that BPM technology will finally fix the typical problems common to almost any IT department: applications that are hard to maintain, missing deadlines when implementing changes to support new business needs, etc.
None of them have finished implementing BPM, so I have no a real world reference to know what is such think like.
I honestly believe that many of those problems only should need solutions based on development process improvement, better analysis of future needs and better project management skills. Heck, even better programmers and designers.
So, my question is:
Is BPM really something that can deliver such great value to the typical enterprise line-of-business application and help having less maintenance problems and more flexibility? Or you are just acquiring yet another component that will suffer the same fate and problems as every other piece of software in your platform?
In other words, what are BPM products good for? What should an organization have in place before trying to implement a BPM platform in order to succeed?

Is [Ayende's][1] approach still the best way to go, with preview 5:
public static void RenderView(this Controller self, string action)
{
typeof(Controller).GetMethod("RenderView").Invoke(self,new object[] { action} );
}

However, there's a catch: I also use [Lazy C++][1], a tool that takes a single source file and generates the .h and the .cpp files. Those .lzz files look like headers, but this tool supports some very mild syntactic benefits, like combining nested namespaces into a qualified name. Additionally, it has some special tags to tell the tool specifically where to put what (in header or in source file).
So my typical SourceFile.lzz looks like this:
$hdr
#include <iosfwd>
#include "ProjectA/BaseClass.h"
$end
$src
#include <iostream>
#include "ProjectB/OtherClass.h"
$end
// Forward declarations
namespace BigScope::ProjectB
{
class OtherClass;
}
namespace BigScope::ProjectA
{
class MyClass : public ProjectA::BaseClass
{
void SomeMethod(const ProjectB::OtherClass& Foo) { }
}
}
As you see, it's still recognizable C++, but with a few extras.
For some reason, CDT's indexer does not seem to want to index anything, and I don't know what's wrong. In the Indexer View, it shows me an empty tree, but tells me that it has some 15000 symbols and more stuff, none of which I can seem to access.
So here's my **question**: how can I make the Indexer output some more information about what it's doing and why it fails when it does so, and can I tweak it more than with just the GUI-accessible options?

One of the things that make it pieceofcrapuous is that the battery is dead, and the power cable pulls out of the back with little effort.
I recently received a non-pieceofcrapuous laptop, and I am in the process of copying everything from old to new. I'm trying to xcopy c:\*.* from the old machine to an external hard drive, but because the cord pulls out so frequently, the xcopy is interrupted fairly often.
What I need is a switch in XCopy that will copy eveything except for files that already exist in the destination folder -- the exact opposite of the behavior of the /U switch.

Shoes.app do
t = para "Not clicked!"
button "The Label" do
alert "You clicked the button!" # when clicked, make an alert
t.replace "Clicked!" # ..and replace the label's text
end
end
This made me think - how would I design a similarly nice-to-use GUI framework in Python? One that doesn't have the usual tyings of basically being wrappers to a C* library (In the case of GTK, Tk, wx, QT etc etc)
Shoes takes things from web devlopment (like `#f0c2f0` style colour notation, CSS layout techniques, like `:margin => 10`), and from ruby (extensively using blocks in sensible ways)
Python's lack of "rubyish blocks" makes a (metaphorically)-direct port impossible:
def Shoeless(Shoes.app):
self.t = para("Not clicked!")
def on_click_func(self):
alert("You clicked the button!")
self.t.replace("clicked!")
b = button("The label", click=self.on_click_func)
No where near as clean, and wouldn't be *nearly* as flexible, and I'm not even sure if it would be implementable.

I've looked at [IMAPI v2][1], but the main problems seems to be that you need to point it to all the files you plan to write out to disk before you start the burning process. I know it has to concept of "sessions", which means you can write to the DVD in several parts, before you finally "close" it.
But I was wondering if there were any other DVD writing SDK's that allow you to be constantly writing files to a DVD and in particular files that are only in memory. It would be more efficient if I didn't have to write the captured images out to hard before they are burned to DVD.
