how to get motherboard id or serial number ?[Delphi]
Is there any free component to get the motherboard serial number in Delphi?
If you absolutely need a component : MagWMI component allows access and update of windows system information using Windows Management Instrumentation(WMI)
If you are looking for a free Delphi WMI library, have a look at GLibWMI project by StackOverflow user Neftalí

Do I understand you correctly, you need all presented network devices files in /dev? Then just run
ls /dev/net* /dev/bge*
and parse results.

I've been using Delphi (Turbo Pascal before that) and have always been a windows guy. My wife bought me one of the new iPads for my birthday and I used it for the first time last night. Wow!... I had no idea how addicting that thing can be.
So, now I need to think about writing an app or two for this iPad. I'm guessing I need to upgrade from Delphi 2010 to Delphi XE2 and I'm looking for a good Delphi resource on development and distribution of iPad apps.
If you want to go the Delphi way you have to upgrade to XE2.
Google for (FireMonkey iOS).

Bob Swart has a course manual called 'Delphi XE2 native iPhone/iPad Development'. It is not free, I have no stocks in it, but I can recommend it.

I think to compile a program for an iPad, you either need Delphi Prism, which creates a .NET application that could be run in Mono, a cross platform .NET framework.
Or, if you want to write native code, I think you will need a MacBook to compile the last step and publish it to your iPad. I think there is no compiler included with Delphi XE2, that runs in Windows and creates an executable for the iPad. The compiler for iOS (the FreePascal compiler, which is shipped with Delphi 2) needs to run on a Mac.

I have been at RAD Studio XE2 World Tour here in Poland in Cracov and I really love new features, so Im almost sure, Ill buy it. But now I downloaded trial version and I want to ask about two things:
Firstly: What can I do with it? I mean - can I build for example one free application and distribute it over Internet? It would be freeware application written within these 30 days. License is quite long and I cant find restrictions like that.
Secondly: If I install this trial anything bad can happen to my Delphi 2009 (Professional)? I have a lot of IDE experts, additional components, important projects etc etc - I dont want to lose anything. In short - is it better to install it on VM?
You are not allowed to distribute applications or components written with the trial edition of Delphi.
I've installed 'full' XE2 onto a VM which already had Delphi 7 and Delphi 2010 on, and haven't seen any adverse effects over the last couple of days. All 3 environments appear to get along fine, as has long been the Delphi tradition.
Once I get a chance I'll stick it on my 'main' development VM, which is currently Delphi 2007.
However, I don't know about the trial version aspect of it. I wouldn't expect it to behave any differently but if you're concerned about your production/work environment, I would strongly suggest that you isolate your trial explorations to a VM... - just to be safe. :-)

I am trying to write a program which will listen to the serial input from Arduino board connected via usb, and sending output to serial port (COM4). But I don't know how to get input from serial port in Delphi. I need program to listen to the port, and whenever the input comes, it should react to it. Any suggestions?
http://sourceforge.net/projects/tpapro/ is a freeware tool we've used with great success for many years.
The already suggested tpapro will probably also do it, but I myself use TComport, which I consider slightly easier to use. It will has an event property onrxchar that triggers whenever a character arrives (and several options for other kinds of packets, including ASCII linediscipline).
I use it pretty much for the same kind of stuff, albeit with microchips mcus.
I've used the Comport library of WinSoft for many... years. It´s excellent (0 bugs) and works with any version of windows.

If I stick with Ms Jet 4.0 (Ms Access 2000-2002) to develop my desktop database program, do you think my app will become obsolete pretty fast? That is from using old db engine that will not be available in the latest windows OS like Windows 7?
Or Ms Jet 4.0 is still a safe bet?
I'm using D5 and ADO.
Please share your thoughts and opinion :)
Thanks!
Ms Jet drivers are not supported on x64 bit OS so IMHO you should no longer use it. SQLite is a great choice for an embedded database.
I would rather try Firebird Embedded. There are plenty of components to access this database (like Zeos) and Firebird Embedded is very easy to deploy (just copy few dlls and database file to output directory).
Question was asked: "Is Ms Jet 4.0 still a good choice to develop Desktop Database App?"
The answer is No, it's a terrible choice. It's old, outdated, and basically unsupported.
Jet 4.0, DAO 3.6 and ADO are part of the Windows operating system since Windows 2000 and is present in Windows 7. I also don't see Microsoft removing those from the next version of Windows although I do't have any official or unoffical quotes on that.
Since SQL Server Express is free, I think it would be quite stupid to use JET for a multi-user network based application. It was only used in the past because there was no free version of SQL Server.
But if you want a simple database app that just runs on a single workstation then JET may well be an easy option considering ease of deployment etc.
