Thanks for the recommendations. I was looking at those two earlier. I've opted for the Microsoft one as it's most likely I'll be able to apply as I go and thus get a firmer grasp.

I love the idea of the cloud based storage and services but having to pay MS to host it based upon things like used space, bandwidth and other factors seems to me to add a layer of financial complexity to application roll-out, implementation, and pricing to clients.
It also seems to open you up to potential abuses by outside clients that could write error filled code that drives your transaction and data rates through the roof making you partially responsible for what could end up being a huge bill if things go pear shaped.
Does anyone know if there are plans to allow the Azure platform to be run within a companies own cloud or is MS really focusing on JUST offering this as a hosted service in their data centers only as part of their long term revenue stream? I could see this, and to be honest it would not surprise me in the least, but I was just wondering if anyone had heard anything.

That I do not know, but you could build your own cloud with the open source version of Eucalyptus[^].

I am an ASP.NET web dev but I am trying to build myself a little desktop application that takes control of another application for me.
What I want it to do is pretty simple, type some text into a textbox on another application then click a few buttons for me. Problem is I don't even know where to start or what language would be best to write this in? Can anyone point me in the right direction.
I can give more information for anyone who is interested
Thanks,

Hi,
I would do such things (and most others) in C#.
For keyboard input, .NET has a SendKeys class.
For mouse input, you would need P/Invoke to call native code in Windows DLL libraries, such as
[DllImport("user32.dll", CallingConvention=CallingConvention.StdCall, SetLastError=true)]
public static extern IntPtr SendInput(int count, ref INPUT input, int size);
[DllImport("user32.dll", CallingConvention=CallingConvention.StdCall, SetLastError=true)]
public static extern IntPtr SendInput(int count, ref INPUT2 input, int size);
[DllImport("user32.dll", CallingConvention = CallingConvention.StdCall, SetLastError = true)]
public static extern IntPtr SetCursorPos(int x, int y);
public struct MOUSEINPUT {
public int dx;
public int dy;
public int mouseData;
public int dwFlags;
public int time;
public IntPtr dwExtraInfo;
}
public struct INPUT {
public uint type;
public MOUSEINPUT mi;
}
public struct INPUT2 {
public uint type1;
public MOUSEINPUT mi1;
public uint type2;
public MOUSEINPUT mi2;
}
Now most of this is considered a hack as you can't do it reliably: it suffices for another application, window or control to suddenly get focus or being shown on the display, for your keys and/or mouse clicks to be intercepted by them (and maybe causing havoc).
The better way is to use application interfaces, if they exist.
Example: there are "Primary Interop Assemblies" for controlling Office from .NET

This is great thank you, I'll have a go at this, the application is for personal use so it being a hack is fine.
Basically I am an online poker player and there is a guy who is VERY bad. So I plan to keep pressing the search button until he sits down and then have the application very quickly sit me in the best seat available before all the others players get in there.
There are alot of commercial applications that do very similar things but for the life of me I didnt know where to start.
Thanks,
Colum

Is their any good ways of sharing the load between us?

You'd need to break down the job into smaller tasks, before you start dividing these among the workforce. You could also opt to let each participant choose the task that they're going to tackle next - the list itself is the thing that you want to focus on. If you find this stuff interesting, then continue your adventure here[^].
You might also be looking for a way to (securely) share code. There's a list with software that can help you to archive and share your code on the Wikipedia[^].

i have not been in a professional development very long, just under 1 year. i have however had the desire to produce professional quality software for sometime now.. i started thinking the other day that i wanted to make a list of items that i could pull from when i sit to design the softwares that i will be developing.
To start off, i have run in to theses parts multiple times in my short development life.
Logging - the ability to log events and errors.
Updates - hopefully semi-automatic.
those are the big ones, but i have seen the following in abundance too.
Instance Management, Extensibility Management, Threading Management (Esp in a GUI), Persistent Settings Management, and then Security/Encryption Management.
i can elaborate on any of these if asked, but lets throw these around the room and see what YOU think. I'm sure I'm not the only one that would like to have a new or different approach to choosing features for the next application.

I was thinking about a scenario which is often seen. Let's start form the user perspective. He opens a web page and there is some data table and filters like that:
Filter by: <field names="" combobox="" here=""> equals
User chooses a field name and enters some value and submits that.
Web application (presentation layer) takes user input and transfers the request to the web service (using automatic .NET XML serialization). So it seems data transfer object pattern can be used here.
Then my web service transforms that DTO to some valid query. Let's assume we are using some OR/M tool to query it for objects which satisfies the query. Also let's assume that OR/M tool offers some easy way to construct dynamic queries (BTW, LINQ-to-SQL has some problems with this).
So the question is - how to better pass data from user form to the data access layer (OR/M tool) so the dynamic query could be generated with less hassle? It would be awful to have web method for each field like this: GetCustomerByName(string name), GetCustomerByCity ... and so on. Then I have to analyze the user input and call appropriate web method. But maybe it is the right way?
I prefer some method GetCustomersByFilter, so then I can almost directly pass the request to web service and then can convert the request to query in OR/M servicing component. But what to pass to this GetCustomersByFilter method? Dictionary with field names as keys? Many nullable parameters? Custom objects?
It would be nice to use the same data structures that are used to pass data to the web application - the same data transfer objects, I guess. Like this:
Customer[] GetCustomersByFilter(Customer filter);
but then I have to allow all the fields of Customer to be nullable so I can later see which fields are used as filters. And if that does not correspond my business/validation rules (if rules say - some property cannot be null) than it would be a bit confusing. Also if I would like to use some generator to create web forms based on my DTO objects, it would be impossible to mark required fields easily just by detecting if some field is nullable or not.
So maybe I need some other object, like CustomerFilter with all nullable fields? Wouldn't it be overkill to have two classes for each object (also, accounting that those DTOs are converted to domain entities later - then we have even more classes)?
This dynamic filtering issue is really bugging me. Has anybody any experience with that, especially using domain driven design?
Thanks.

Hi all,
I've started designing a document management system based on SQL Server and vb .net. I find this an interesting project, why? Document management systems have grown to be too complex. What are the main subjects to cover? I want to control the document flow through a product development project, then to the production cycle and maintenance. This means avoiding a catalog structure and always looking for the latest versions of CAD data, bill of materials and so on.
It would be nice to have some feedback, is this a good idea?
Best regards,

Sharepoint is flexible, and, I find relatively simple to utilize and learn, plus there are TONs of examples, source code, add ons, and it's industry standard, uses SQL Server, can use .NET plugins, and more... Seems kinda like a moot effort to write your own.

Yes, its a brilliant idea.
On the contraty, you can check for existing technologies like MOSS or DotNetNuke or other CMS on the features they provide.

That depends on what you're trying to achieve. There's a lot of those out there, and lots of competition means that there's a living market.
You stated yourself that the current DMS-systems are too complex. Do a quick-poll on your collegues and ask them what annoys them most about the current system. Ask them what features they miss, places where people get stuck, make a list - and check it twice 
If you're looking for a fun project from which one can learn, then I'd say that you'd chosen a good candidate.

I am currently going down the same path and creating project and document management database software. I started the project because our company (4 employees) would not buy typical management software which is aimed at larger projects and companies. I started using excel, then had a brief stint in Outlook then I moved to Access and I am currently evaluating the move to C++ and mySQL. Anyhow my journey so far I have done the following things:
So far I have done the following:
Outlook
(Dont try programming with vbscript (forms for contacts, calender, tasks ...) unless you are a sucker for punishment)
Synchronize routines for outlook contacts to access
Rewired the outlook calendar to a timesheet program. It now synchronized with my access timesheet database.
I rewired the task manager to a project manager and then ran synchronization routine through exchange server to my other workers, but I kept overloading the buffers. This pretty much convinced me to switch over to ACCESS.
Document Control
Created a standard document that outline the font and format that all my documents all look and feel the same. Created excel and word templates that I base my forms, letters and so forth off of. I did write a little routine for document control which helps me know which document are allowed for use with my other employees.
Document Folders
Decide whether your folder locations will be and whether this information will be hard wired into the program or will you created a database that will track and add this information as your company changes. I created routine to create the folder structure automatically with each new project to maintain the consistency of the work flow. One problem that I am battling with my IT is that they want my folder paths to be reduced which affects file access and backing up data.
Synchronization
I plan to be able to incorporate using your laptop or packaging information on your jump drive to work at home or on the road. In effect I have created addition fields in my table with reference the origin of data, which would reference the equipment and the ID number of the field of the remote table. The other thing that I am tracking is Created Date, Modified Date, and Accessed Date which is something that typical word processing documents use. I am contemplating adding more fields such as the person who created or modified or last accessed the data. It would me more used to track how bad data was entered into the main database.
Search Engine
With project management and document management it is easy to get a lot of information to manage so I spent a considerable amount of time to come up with a solution.
Automation
The idea of the project was to reduce the work load not increase it, so I spent a great deal of time creating automation engines where possible. Its one of those things that you may spend a lot of time getting right, but I feel it will be worth it in the long run.
This is my journey todate. I hope that you can mine some useful nuggets of information from this. When I finally get my prototype done I am considering using a program call Qt which was coincidentally created in Norway. I am reading it right I should be able to use Qt compile a linux and microsoft version.

Hello to all.
I am hoping you can provide opinions based on real world experience as to whether developers need to have local administrator rights on their machines or whether they can run on lower authority and if so what the recommendations for the minimum settings to use would be? More details around the environment follow ...
Our organisation is large enough to have separate systems administration and development teams. The organisation has a Standard Operationg Environment (SOE) that is used for all general office workers. Our developers currently have local administrator rights on their standard logins. Due to some recent scares with viruses coming into the network the systems administration team is making a case to management to have the developers normal login accounts run at a similar privilege level as the general office workers and either:
- provide them with a second account to use to load / remove software
- request that they go through the service desk to get software installed
The overall environment is Windows XP with MS Office 2003, Outlook 2007 and some other tools. The development environment is .Net, C#, SQL Server 200/2005 and a variety of other tools.
Over to you ... what are your thoughts?

Well - if you run with elevated privileges, you're kind of assuming that your applications are going to be deployed on systems that require elevated permissions. If your applications are meant to run in a lower security level then you've just made it harder for yourself to test that your application will run in the environment that you want to use.

Thanks for the answer.
The vast majority of the applications being developed are web based. There is some middle tier components also developed using the .Net environment. We can operate on the basis that the deployments will run with appropriate security set and / or the correct impersonations being done. The appropriate security is highly unlikely to be anything like local administrator on the platforms that the application is being deployed to. In fact I suspect that it may be argued that running at lower privileges may enforce the correctness of the impersonations.
So my question extends out to cover: what would break if the development tools were run on a machine where the user was not running with local administrator privileges? Conversely what setting would need to be made to allow the development tools to work correctly without having to provide local administrator rights?

Pete makes a good point. I can't speak specifically to web applications, as you mentioned in your other post, but I have to agree that giving admin rights would encourage bad habits.
You don't, however, want to sandbox the developer too much. If you start blocking things like write access to the "Program Files" directory, you'll just have a bunch of angry geeks on your hands. The users may not need to touch that, but the developers will want to be able to test installers and such.
On the other hand, if you're ONLY doing web development, a complete lockdown might be possible. It would depend on exactly what's needed to run the IDE, compile, and deploy a web app... I'm sure someone else can give a more complete answer on that subset.
I would suggest, however, that you put a process in place for developers to request temporary admin access when necessary.
For example, I'm a front-office developer in a large company with a separate IT support staff... I can write freely to most of the hard drive and the registry, but I can't change system or security settings, or kill admin-level processes (Such as the scheduling app they use that occasionally makes my machine unusable for 20-30 minutes)... My only major gripe is not being able to run a defrag without asking one of the IT guys first.

Thanks for the comments.
I take the point about the temporary admin access and our IT area were thinking of either:
- providing the developer with a second account to use to load / remove software
note: this account would not be connected to email, etc. and so could not be used
full time to replace the main account
- request the developer go through the service desk to get software installed
note: software installation e.g. tools and other apps, is a fairly rare event in our environment
Your example is interesting. Do you know if you are set up as local administrator with group policy applied over the top to restrict your access to security, etc?
I look forward to other people's feedback as to minimum requirements for the IDE.

No, I'm not a local admin... Hence the inability to run a defrag. I think I'm in there as a "Power User"... Hard to tell, as I can't access the users/accounts config.

If you want faster development yes. Every time you put up a wall you slow down progress. Reverse the question and ask: Is it really a problem if my developer has admin access on his local machine? I mean, is it the development team that is bringing in these viruses/bad progs? Developers are usually pretty computer savvy, so sometimes I find this argument hard to swallow. Maybe anti-virus would be a better solution than locking access?
If you can't think of why this would be a problem, then why put up roadblocks? Here, your suggestions are wholly adding to the cost of development, and decreasing efficiency. Are viruses that prevalent in your network?
A user can be an admin on their machine and still have restricted access to other machines, and that may be a more viable solution.

This would really depend on how "in the weeds" your developers are getting. As a developer I find myself installing and removing applications almost every other day for integration testing and evaluating new development tools. In addition, I have occasion to stop and start services on my development box when things go haywire. Editing and removing registry entries is not uncommon as well. All of these are much easier with local admin rights.
If your developers are doing simple web development (HTML, Javascript, Flash..etc) then they probably don't need admin access. However, any of the higher languages (Java, C/C++, C#, Perl...etc) I would definitely recommend admin access.
One solution I have seen to your dilemma is install virtual environments. This allows the developers to create their own machines with what ever rights they want, while still controlling the actual hardware. Unfortunately, the virtual env. tends to be slower and can affect compile and testing times.
My guess is that your virus scares were not on the developer boxes, they tend to be more careful than your average user. This fight is not uncommon.

I have a data model where each record has a "next version pointer" to track updates to the items. As it stands now, the object looks something like this:
Public MustInherit Class VersionedDataObject(Of T As VersionedDataObject(Of T))
Private _next As T
Public Property NextVersion() As T
Get
Return _next
End Get
Set(ByVal value As T)
If value Is _next Then Exit Property
_next = value
If _next Is Nothing Then
_nextVersions = Nothing
Else
_nextVersions = New NextVersionIterator(Me)
End If
End Set
End Property
Private _nextVersions As IEnumerable(Of T)
Public ReadOnly Property NextVersions() As IEnumerable(Of T)
Get
Return _nextVersions
End Get
End Property
End Class
The question is, when NextVersion is Nothing, would you return Nothing from NextVersions (as I am doing now) or an IEnumerable with no items?
