Need help on Beginning HL7 - hl7

hI
Can anyone please guide me to Creating HL7 Version 3 messages for the first time. I need to understand the design of XML based HL7v 3 message. I want to design an interface engine in Java. Have tried to find.. but cannot see anything for beginners.
Please help

HL-7 documentation has to be purchased from hl7.org. They control copyright and so legal free copies aren't available AFAIK.
If you feel thrifty and are willing to work out some of the information yourself, the HAPI project might be a good place to start. If you look at the code you can see how some of the different segments are represented.

There's a tool I've been using lately that helped me on that. It's called HL7 Soup which is a HL7 Viewer.
It's advantage over other products I used is it's easier to understand messages and its structure, which helped me learning lots about HL7.

SOAP & iOS: Any guidance?

I am trying to use WSDL and SOAP with my iOS application. And I am desperate. Seems the 2 code generators, Sudz.com and WSDL2OBJC are not suitable. One has TONS of memory leaks, and the other one has other minor problems.
I want 3 things:
1) A test WSDL file for learning, and a test service wrapped around it. I couldn't find any, no matter how hard I tried.
2) A good tutorial on the matter. After a lot of searching, I still haven't found any good one.
3) A little more guidance on what to do, please.
Hi Christos: I wrote several WSDL2Objc tutorials here http://brismith66.blogspot.com/search/label/iPhone%20Development I use various publicly accessible services for the samples. I hope my tutorials fall into your "good" category :-)
Regards,
Brian

OmniThreadLibrary Overview

Is there a place where there is an introductory overview of the OmniThreadLibray for Delphi?
I have the current code installed in Delphi XE. The examples work. I've been looking over the associated The Delphi Geek blog with usage examples. Gabr admits the documentation does not exist. I would like to get a handle of the structure of the framework before diving into specific examples. I do have an understanding of the usage of TThread so I don't need go to a Threading 101 site.
The framework has shown to have a loyal following and I'd like to think I just haven't looked in the right place.
The author of the OmniThreadLibrary, Primož Gabrijelčič, is working on a book to document the library. It started off as a wiki and has been growing.
OmniThreadLibrary Book Wiki
The ebook: Parallel Programming with the OmniThreadLibrary
As sections are completed in the Wiki they are added to the eBook. From Primož's blog:
In accordance with the Lean Publishing Manifesto, Parallel Programming
with OmniThreadLibrary is published as it is written. When I’m happy
with a chapter (or even with a section, if it is important enough), I
click the Publish button on the LeanPub site and new, updated book is
available to all the readers
As far as I know, there's no overview of the type you're talking about. The closest there really is is the examples. They provide demonstrations of the things you can do with OTL, and you can study the code to see what they're doing and how it's implemented. I don't think you'll find anything better than that, for the moment at least.

introduction to latex

what's a good website that has an introduction to latex for window users? I will be using it mainly to write math homework problems and probably then converting it to a PDF to print out. I'm hoping somebody has bookmarked a good link already so I don't have to search. Thanks!
You should start from this "not so short introduction to latex"
http://www.ctan.org/tex-archive/info/lshort/english/lshort.pdf
I recommend this one: http://en.wikibooks.org/wiki/LaTeX
LaTeX works the same across platforms (and even across its distros, except some may provide features that others don't), so it doesn't really matter what your platform is.
I find that Andy Roberts's site is perfect for beginners, it has a lot of newbie exercises and takes you by the hand in a perfectly controlled fashion. It is my online reference for my basic latex questions.
http://www.andy-roberts.net/misc/latex/index.html
The LaTeX Community site doesn't seem to have any beginner tutorials, but it does have a number of articles that go into specific uses. If one of those articles covers what you're trying to do, then it may give you a headstart.
Outside tutorials, as a beginner getting into LaTeX, I found the TeXnicCenter Open Source IDE to be very useful. It makes life a lot easier when you get some syntax colouring and templates to help with common structures like tables.

Tutorial for Pascal/Delphi for C++-Coders

I'm a C++-Programmer. But now i have to learn Pascal/Pascal. Are there any websites, documents around that can teach someone with my knowledge the difference?
It shouldn't be too difficult to pick up. C's design was influenced by ALGOL and Pascal, so the semantics and logical flow are going to be pretty familiar. You can get an overview of the differences between basic Pascal and basic C here.
But you tagged this as Delphi and you mentioned C++, which implies that you'll need information on OOP techniques. Try this article or this one, which compare object-oriented programming in Delphi with C++ and other languages. Both are a bit dated, but most of the basic information in them still applies today.
If you have any specific questions about language features, feel free to ask them here, and welcome to Stack Overflow!
You can check Essential Pascal written by Marco Cantù, is a introduction to the Pascal programming language. you can download a free copy from here.
Another excellent site for beginners, is Delphi Basics, this web site provides help and reference for the fundamentals of the Delphi language. It gives an introduction to the Delphi Object Oriented Language for newcomers.
A website that helped me a lot when I learned Delphi was http://www.delphibasics.co.uk/. I still use it. It presents common methods in a nice way.
You might consider this post on beginner guides to Delphi. It has some good links included that may be rather simplistic for you, but can still take you a long way.
Marco Cantu (mentioned in several answers) also has a book series called "Mastering Delphi." It is a great (maybe only) top to bottom resource. Everything Delphi is in it. But the last edition is for 2005. Four versions of Delphi have been released since. There are a couple of update sheets available from Marco's website (D2006 was mostly a bug fix of 2005). And Marco also has the Handbook series, but that is aimed at people who already know Delphi and are looking for help on the newest improvements.
Personally, Delphi is my favorite language. I hope you enjoy it!
your name sounds german so you might wanne check these pages out
delphipraxis
it's not really a comparison for cpp and delphi/pascal but you'll find a lot of information
due to me being a new user i'm not able to post a second link. but search google for delphi forum..
The Free Pascal documentation is another great resource:

Is It Time To Rethink The Delphi Help File System?

The majority of components available for Delphi do not have HTML Help files for Delphi 2009. Many components including some very popular commercial components only have HLP and CHM help files.
Many of the third-party components are no longer being actively developed but are used by many developers. As a result there is no IDE help for these components.
There were very few complaints about the old CHM help files but today there are a large number of complaints about the help file system. Maybe it is time for Codegear to rethink the type of help file system used.
One of the complaints that I have about it is even when you install components that provide HTML help files the Contents Tab becomes corrupted where by previously installed component contents are removed.
Are there possible alternatives for Codegear to consider?
I have the same feeling. The old help system helps me more quickly to find an answer.
One idea is to maybe to model it after the Delphi Wiki at: http://delphi.wikia.com/wiki/Delphi_Wiki
The wiki actually isn't set up that bad, especially with the VCL link in the left frame.
It's fairly pleasant to look at, has a decent search, includes issues, examples, cross references, and what I like the most: user comments and tips.
Actually regarding the user comments and tips, the thing I like most about the PHP documentation at www.php.net/docs.php (which I think is the best programming documentation I've seen) is the user comments and tips.
If they can integrate the great layout that you'll find at Delphi Basics into it, and allow 3rd party components to add their help files into it, then they'll have a complete reference. (But the 3rd parties will obviously have to restructure their help files to the new format - whatever it ends up as).
The wiki also has sections for Tutorials, Tips and Tricks, References and Popular Articles. And I think it could also become the all-encompassing code-repository we all would like.
An option to download the help wiki should be allowed so it can be accessed offline.
And they'll have to figure out how to get the F1 key to work to properly search the wiki/help file, whether online or offline, and give the most relevant results.
The trouble with the Wiki now is that it is not complete, and the full set of Delphi help files need to be incorporated into it.
This might be a pipedream, but something like this would be my ideal.
This is a pet hate of mine. The Delphi Help has just got worse, although with a recent slight improvement. I honestly believe that this is one of the things holding back its adoption.
Micosoft introduced Help3 for VS2010, so maybe we will see it in Delphi too:
here is a blog post which answers the question "Why A New Help System?"
http://thirdblogfromthesun.com/2010/10/the-story-of-help-in-visual-studio-2010/
It quotes an internal paper, which led to the new "Help3" project in
early 2008:
"The paper described the following
issues with the help experience in
Visual Studio:
Not being able to find the information you need is a common
problem. F1 Help and Search do not
work as well as they should.
The performance of the help system – primarily start-up, topic-load,
local search results – is one of the
biggest problems.
The offline MSDN library install is fragile due to the complexities of
the help system.
The proprietary nature of our help format offers little incentive for
partners to develop authoring tools
and cannot be easily adopted by
developers in their own products.
On the content production side, the help platform saddles us with
outdated tools and processes.
Finally, and most importantly, no single team at Microsoft owns solving
these problems."
