Thanks,
What other operating system do you recommend, and is it wise to go out a separate computer PC 3 or does it make any difference to go out the same way it went in (my original thought was it wouldn't be able to send data out the way it came in). Does the firewall operate along with the OS or is it completely different. Is there one I could buy that would meet my requirements or would I need to write it myself, if so suggestions where to start, C# code, etc.

On the maximum paranoia setting, I'd go for any Linux-version that can be compiled by hand (and verify the MD5 after downloading). Any minimum installation would do. Recommended basic settings here[^].

That will depend mostly on the client; the hardware and drivers do not care which way the data flows on a TCP-connection. You DO want to block incoming connections - on almost every port, for almost every IP.

There can be multiple; next to the hardware-firewall there's a firewall in Windows. Additionally, if you're using services, there's a firewall pattern[^]. That's usually something you build yourself, as only your app can validate a request.
Happy hunting 
--edit
As an alternative; PC2 could block *all* incoming connections - it could fetch it's data from PC1 using a secured service. You'd be polling a bit, but then again, the PC won't be doing much other stuff

Thanks,
The information you gave me was very enlightening, I really like your last idea about polling.

What do you think of the following:

Sounds good; I added it to my bookmarks
The complexity of iptables makes it hard to configure (which makes the chance of mistake bigger) and one is less inclined to check/update a complex system than it is with a kind and easy system.

Dear all 
I converted a sample from C# to VB and get an error message. It looks simple, but still I don't understand... Would it be possible that C# allows calling an event directly, while VB doesn't? Or did my conversion tool go wrong? 
Here's the short sample code:
private void OnWaveControlContextMenuPopup(ContextMenu menu)
{
if (this.WControlContextMenuPopup == null)
return;
this.WControlContextMenuPopup(menu);
}
where WControlContextMenuPopup is defined as an event:
public event WControlContextMenuPopupDelegate WaveControlContextMenuPopup;
After conversion I get the error message "Public Event WControlContextMenuPopup in an event and cannot be called directly. Use 'RaiseEvent'...". The error is shown in lines 2 and 5 of the converted code:
Private Sub OnWControlContextMenuPopup(menu As ContextMenu)
If Me.WControlContextMenuPopup Is Nothing Then <-----
Return
End If
Me.WControlContextMenuPopup(menu) <-----
End Sub
What would I have to change in the VB code to get the required result without error?
Thanks for some insight...

Try something like this:
Private Sub OnWControlContextMenuPopup(menu As ContextMenu)
RaiseEvent WControlContextMenuPopup(menu)
End Sub

Thank you, Richard. Is it correct to leave the "if... end if" part away completely?
|
|
|
|
|
Yes, that's correct; RaiseEvent handles that check for you.

C# and VB have differing syntax for doing the same thing. C# uses a syntax that is identical to calling an actual method. The error mesage tells you exactly what to do.
RaiseEvent WControlContextMenuPopup(menu)

|
|
|
|
Thank you for your answer.
Will I just ignore the whole "If..." part then? Because "If RaiseEvent..." doesn't work either. What is it actually supposed to do? Check for the result of an event???
|
|
|
|
|
Yes, you ignore the if code. All it does is check to see if a subscriber is attached before trying to raise the event. If VB.NET, with RaiseEvent, you don't have to do that.

Thank you for your help, and have a nice evening!

1] Data Layers - Would you create one DAL class for each table? Each DAL would have a method for each CRUD operation.
For example I have a series of tables "Extra Work Headers", "Extra Work Material", "Extra Work Equipment"... and a couple more.
Would you put the methods for ALL of the Extra Work tables in one DAL class, or create a DAL class for each?
Right now I have a mix of this. Some DAL's have all methods for a group of tables, but lately I have been creating DAL's for each table.
2] Same question for BL's and Controllers. One Controller for a table group, or a separate Controller for each table?
I see pro's and con's to each approach.
What do you think?
If it's not broken, fix it until it is

Don't think in terms of "tables", think in terms of "operations" -- many operations require changes to multiple tables.
|

While I agree, part of the reason I'm asking is that I'm using a home grown tool that generates code. It creates the Table Scripts, Entities, DAL, BL, Controllers, Models, API Proxy code, etc.
Not sure how that would work from an 'Operation' based approach.
So what I think I hear you saying is to create these objects based on what needs to be done, rather than based off the table?

That's what I'm saying.

I'm all for that.

Which is why I never use anything that claims it can do it. There is no substitute for hard work. Doing it the right way requires time and experience.

I'm working on a long term project. If I tailored the tool specifically for this project, I could make it work

I'm sure you'll learn things along the way, and that's a good thing.

It kinda depends I guess. For example: When you have tables where each record is considered an "object". You should use one class/table. Examples: Persons, tickets, companies, products, ... things like that.
If you have tables that start having calculations or objects that are (complex) joins of tables or where multiple records can makeup one record, you should probably tackle that a little differently.
hope this helps.
