Hi Everyone,
Thank you for all of your responses. It looks like there are lots of books and resources that would be good to review. I'm also going to try posting some of the basics here.
Thanks again!

You want to look at some code of how design patterns etc are applied. MSDN has some really cool sample applications. These applications are full n-tier design and gets stuck right into new concepts like software factories as well as best practices
Try the Microsoft .NET PetShop 4.0

Hi all,
I've got the following sceanrio for a customers project:
- Application running as a service an a server.
- Database running on a different server.
- Lot's of messurement equipment connected to the server.
- Administration-Tool, running on (some?) client's
- Web-Browser-Interface to get information about the facilities state
I'll to use remoting for communication between Admin-Tool and the Service.
But I wonder how I can get data from the service to the admin-tool. The problem is that creating a WebService via
RemotingConfiguration.Configure(...);
with configuration
wellknown mode = "Singleton"
type = "RezeptServiceManager.RezeptServiceManager, RezeptServiceManager"
objectUri ="CoreManager.soap"
this leads (as desired) to a single server-object of type RezeptServiceManager, but these object does not have any connection to the service doing the actual work, therefore dataexchange is not possible.
Accessing the Database from my RemoteObject is no option.
Is it possible to get the Object connected to the service and therefore access the data?
Does anybody can give me hint to solve this problem?
thanx in advance
Franz

I don't understand, I thought you said the remote object "is" hosted in the service?

Yeah, the customer tends to be a bit paranoid - so he dislikes the idea of access his production-database from the net.
Therefore I need a way to exchange data with the service.
thanx

The remote object is hosted on a server therefore the database access is coming from that server not from the proxy object in the client.

It seems that you are running an application on a test computer, and then send information of equipments, connected with the comuputer, to a server. And you wanna use another client computer to access the status of equipments on server database. Am I right?
just like we send blogs to a web server, and others can view the blog though internet.

HI,
I am wondering what to include for the method part of a class diagram. I have already created my program and I'm going back to this to correct it. I know you usually have get and set methods but my TL told me to include what ever my code says, but I use sql statements to get the data and then display them using table adapters using .FILL.Can anyone help me out?
 ;)

Hi everyone!
I'm looking for some informations about the multi tier/layer architecture for a web project (AJAX + tons of javascript) but also with a lot of C# code for the web portal's objects parts. I've found some informations (even some in CP) but I think I need more and go deeper, especially, something that contains examples.
Could someone help me?
Thanks in advance! :]
See you...

At my place of employment we have access cards as a system for entering the building. We have a utility that shows who is in the building, and who is out. This utility gets the in and out employees from a SQL Database.
My supervisor wants a new feature added, and I have been giving the task of doing the design work for this. I have been mulling around for a few hours, considering my options. I was wondering what the CPians think of this idea, or if you guys have a better idea.
The new feature would allow you to select an employee from the "Out of the building list," and set a notification on the person. So, when they enter the building, you will recieve an E-Mail saying "Joe Shmoe entered the building at 5:00 PM." We want this added to enterprise namespace so this can be a re-usable object in any software we design.
So, my Idea is as such:
I would create a service running on one of the servers in the building. The user will look at the In&Out utility, select a user, and say "Hey I wanna be notified when they come in" The service will accept notification request, and store it in a database. The service will constantly monitor the In&Out database, and when a condition for one of the notification requests has been met, it will send an E-Mail to the requestor. Then, the service will remove the notification request from the list.
I have been looking at This Article[^] and I believe a lot of this is applicable to me. What do you guys think?
I get all the news I need from the weather report - Paul Simon (from "The Only Living Boy in New York")

Well - another way to accomplish this would be to use a Notifications system like, say, the one with SQL Server 2005. Take a look at it - it's really very, very good.

Leaving the implementation to one side, the approach taken to establish if an employer is in or out of the building using the card system may not be 100% accurate i.e. employer holds the door open for another, some override over the lock is performed, employer is using a temporary card if they misplaced their assigned one etc... Might be worth making your supervisor aware of this.
As for the implementation if your using sql server 2005 I believe you can use a SqlDependency to check for data changes, it might be worth investigating.

Leaving aside implementation specific details and assuming you have access to DB servers keeping this information.
Whenever you get a request for monitoring someone you can create a trigger in the database. The trigger should get triggered when the employee uses his access card to enter the building. In the code for trigger you can do the necessary processing.
In an even based programming model, you should have events for whenever someone enters or leaves the building (OnEnter, OnExit).
When you get a request to monitor someone you can store that in DB, and when the onEnter event is triggered, you can check against the DB to see if this person is on the notification list.
Of course you have to put in appropriate code to remove the trigger once the condition has been met.
Hope this was helpful

How you seen MAC OS forms and dialogs? Most of them don't have any save button. I was wondering when exactly (and in response to which event) they store data to hard drive.
I wanted to implement a simmilar functionality in MFC Dialogs, I have a grid, clicking on each row of the grid, loads respective data to the controls below the grid. After user changes data in the controls(textboxes, combo, etc) data should be saved automatically.
Which messages would you process to archive this goal? (I thought of KillFocus but there are some issues )

Saving data on each killfocus causes a lot of hard disk engagement. Putting save on killfocus of last control is not practical because later UI might change, or it might be optional, and user might never set focus into it, so there won't be any killfocus.
Anyway, I decided to put that save button, after thinking a little bit more today. As another post suggested here, it's not such a nice idea to put such a feature.
Thanks.

They do. It's in the menu bar. Applications on MacOS X usually do not have toolbars like they do on Windows.
When people want to save, they press the "Apple Key"-S or go to the menu and select the Save item.
Also, to be noted, all applications on Mac OSX (There are some exceptions) have a menu; and it's good practice to have the basic items available ( File, Edit, ...)
Now, on Windows, if you have a Dialog based application, you will need to have a UI mechanism to let the user save the data. Either put a button "save", a menubar or a toolbar.
IMO, it's not a good idea to have an Autosave that replace a save (and "save as") command.

Sorry, I once, out of curiosity, downloaded the tiger version of MAC on a Vmware Hdd. I think it was illegal, so I deleted that. I had not enough time to investigate all parts of the OS. I couldn't see that button, and I don't remember where it was exactly. But you seems to have a good experience with that, so you're right probably. I'm sorry because of such a stupid mistake.

You're right and I added that already today. It's almost a long time since I posted the comment today.
Anyway, thank you so much for your help.

I'm creating a new rule for the IT department, every new deployed system will have an associated Deployment Diagram.
The first attempt, using Visio 2007, I didn't find the best fit Diagram model.
Do you have any tips on tools that could be used ? I prefer
Microsoft tools but another ones can also be considered.
Thanks for any tip !

You could use Rational Rose[^].

Try downloading some free visio templates -- make sure they are UML v2.0
rational rose sucks and it's way too expensive for most teams to justify the cost
if u use eclipse there is the umlet plugin and you can run it standalone as well...you have to get used to it's odd user interface, but if you have the true personality of a software engineer you can figure it out...it also outputs your model diagrams in many file formats...it's free too.
i personally like Artisan RT studio, but again it's tough to justify the costs of these tools.
visio is virtually free if you have win-doz office junk...
check out the omg sysml stuff too...it's interesting, and offers other diagrams as well
kind regards,
David
