I'm hoping that I'll be able to use Flex for any new projects, but a lot of new stuff in our roadmap is additions to the old code.

For example:
- /generated-code
- /dbo
- SomeTable.cs
- OtherTable.cs
- /abc
- Customer.cs
- Order.cs
The schema names are there to isolate the generated classes that an app will need. For example, there is an ABC app, that will pull in the generated code from this central folder. I'm doing that on a pre-build event, like this:
> del /F /Q $(ProjectDir)Entities\generated\*.cs
> copy $(ProjectDir)..\..\generated-code\abc\*.cs $(ProjectDir)Entities\generated\*.cs
So on every build, the Nant script runs the generator which puts all the code into a central holding place, then it kicks off the solution build... which includes pre-build events for each of the projects that need their generated classes.
So here's the friction I'm seeing:
1) Each new app needs to setup this pre-build event. It kind of sucks to have to do this.
2) In our build server we don't generate code, so I actually have an IF $(ConfigurationName) == "Debug" before each of those commands, so it doens't happen for release builds
3) Sometimes the commands fail, which fails our local build. It will fail if:
- there is no generated code yet (just setting up a new project, no database yet)
- there is no existing code in the directory (first build)
usually these are minor fixes and we've just hacked our way to getting a new project or a new machine up and running with the build, but it's preventing me from my 1-click-build Nirvana.
So I'd like to hear suggestions on how to improve this where it's a bit more durable. Maybe move the copying of the code into the application folders into the NAnt script? This seems kind of backwards to me, but I'm willing to listen to arguments for it.
OK, fire away :)

There is an application written in Visual Basic 6.0 (not by him).
One of users reported that when it run on Windows 2000 and tried to scan folders on disk it raised box with message:
*Run-time error 1012 Error accessing application data directories*
We couldn't google anything about it and didn't find anything about runtime error 1012 in VB6 help files.
My guess was that VB calls some old API function which returns folder to which app has no access (private, ciphered, belongs to other user and app is run by user without needed privileges).
But we could not reproduce this (on Windows XP professional).
Anyone meets with bug like this in the past?

Hash codes won't do it, because I can't afford hash collisions i.e. the representation must be unique and repeatable.
The numeric representation will be used to perform efficient (hopefully) compares. The creation of the numeric key will take some time, but it only has to happen once, whereas I need to perform vast numbers of comparisons with it - which will hopefully be much faster than comparing the raw Strings.
Any other idea's on faster String comparison will be most appreciated too...

I would like to be able to detect if the number they type is correct or not. The phone system does not have access to a list of valid numbers, but instead it will validate the number against an algorithm (like a credit card number).

- It must be difficult to type a valid random code
- It must be difficult to have a valid code if I make a typo (tranposition of digits, wrong digit)
- I must have a reasonnable number of possible combinations (let's say 1M)

The module I am starting with is responsible for importing data from a variety of systems into our database. About 5-6 times a year, a new client asks us to write a new import for the system that they use. Presently, this requires us to release a new version of our software for each new import option we add to the application.
One of the goals of the rewrite is to make the application support plug-ins. Every new import can become a separate assembly which the host application will recognize and allow the end user to interact with. This will hopefully simplify life to some degree as we can simply drop a new assembly into the directory and have it be recognized and used by the main (host) application.
One of the items I am struggling with relates to the differences between the import options we currently support. In some cases we actually let the user point to a directory and read all of the files within the directory into our system. In other cases we allow them to point to a single file and import its contents. Additionally, some imports have a date range restriction that the user applies while others do not.
My question is, how can I design the application in a manner that allows for some flexibility among the imports we build and support while at the same time implementing a common interface that will allow the host application to easily recognize the plug-ins and the options that each one exposes to the user?

I'm looking for secure ways to pass data between a client running Flash and a server. The data in question will be generated BY the Flash app, which in this case is your score after finishing a game. I want to verify the data is untampered on the server. What are some good methods of getting this done?

Each class library project outputs a single binary, e.g. Company.Common.Serialization.dll.

Some arguments in favor of project references:
- Project references would allow users to debug and view all solution code without the overhead of loading additional projects/solutions.
- Project references would assist in keeping up with common component changes committed to the source control system as changes would be easily identifiable without the active solution.
Some arguments in favor of binary references:
- Binary references would simplify solutions and make for faster solution loading times.
- Binary references would allow developers to focus on new code rather than potentially being distracted by code which is already baked and proven stable.
- Binary references would force us to appropriately dogfood our stuff as we would be using the common library just as those outside of our organization would be required to do.
- Since a binary reference can't be debugged (stepped into), one would be forced to replicate and fix issues by extending the existing test projects rather than testing and fixing within the context of the consuming application alone.
- Binary references will ensure that concurrent development on the class library project will have no impact on the consuming application as a stable version of the binary will be referenced rather than an influx version.

I'm creating a custom Information Management Policy in MOSS. I've implemented IPolicyFeature, and my policy feature happily registers itself by configuring a new SPItemEventReceiver. All new items in my library fire the events as they should, and it all works fine.
IPolicyFeature also has a method ProcessListItem, which is supposed to retroactively apply the policy to items that were already in the library (at least, it's supposed to do that for as long as it keeps returning `true`). Except it doesn't. It only applies the policy to the ***first*** item in the library, and I have absolutely no idea why.

MVCC gives you automatic auditing for applications that require a detailed history, and it also relieves pressure on the database with regards to update locks. The cons are that it makes your data size much bigger and slows down selects, due to the extra clause necessary to get the latest version. It also makes foreign keys more complicated.
(Note that I'm *not* talking about the native MVCC support in RDBMSs like SQL Server's snapshot isolation level)
This has been discussed in other posts here on Stack Overflow. [todo - links]
I am wondering, which of the prevalent entity/ORM frameworks (Linq to Sql, ADO.NET EF, Hibernate, etc) can cleanly support this type of design? This is a major change to the typical ActiveRecord design pattern, so I'm not sure if the majority of tools that are out there could help someone who decides to go this route with their data model. I'm particularly interested in how foreign keys would be handled, because I'm not even sure of the best way to data model them to support MVCC.

Occasionally, on a ASP (classic) site users will get this error:
[DBNETLIB][ConnectionRead (recv()).]General network error.
Seems to be random and not connected to any particular page. The SQL server is seperate from the web server and my guess is that every once and a while the "link" goes down between the two. Router/switch issue . . . or has someone else ran into this problem before? | 0 |

I plan to use TCP packets for strategic data and UDP packets for tactical data.
I am looking for network library recommendations. I have found a few options, such as GarageGames' Torque Network Library (C++), RakNet (C++), and the lidgren network library (C#):
