How Do You Place ( and ) Characters in Code?
How Do You Place( and )characters in Code? Example (302). THANKS.
What do you mean?
"(" and ")" are used in expressions much the same way they are used in algebraic expressions. They are also used to enclose a type name to form a cast specifier, to enclose the expression that defines the condition of an if, for, while or switch statement and they are use to enclose the formal argument list in a method declaration and the actual argument list in a method invocation. They can also appear in string constants. I probably left out a couple...

How often do you place remarks in your code?
Maybe some of you may consider this a stupid question, but how many times do you place reamkrs in your code.
I usually put a remark nearly in everyline I do in java (or some lines) to describe what is happening. However I am not sure whether doing to much reamrks is seen as a wrong thing!!
what do you people think?Is that wrong?No, but It isn't the question that I'd ask. I'd
rather ask some of the following ones:
- does it help with understanding the code?
- does it add anything that's not obvious from the
code?
- if something is not obvious from the code, why not?
bad design? bad naming? or simply a complex
algorithm?
- how much overhead does it add to maintaining the
code? (if I change any of those 4 lines, I'll
probably have to change the comment as well, and
chances are that I'll forget).But from time to time you forget what has been made isnide the code, or worse you have to read other people code. All that you say is true, but I believe that having remarks will help other developers reviewing the code after one is gone. -
Re: How do you create and use "common" type classes?
Hi,
You have 2 potential solutions in your case :
1- Sub-class TextNullable class of Framework and add your methods in the
sub-class.
This is the way Domain class work. Only Nullable classes are sub-classable.
This is usefull for Data Dictionary.
The code will be located in any partition that uses or references the supplier
plan.
2- Put your add on code on a specific class and instanciate it in your user
classes (client or server).
You could also use interface for a better conception if needed. The code will
also be in any partition that uses or references the supplier plan where your
add on class is located.
If you don't want that code to be on each partition, you could use libraries :
configure as library the utility plan where is your add-on class.
You can find an example of the second case (using a QuickSort class,
GenericArray add-on) with the "QuickSort & List" sample on my personal site

I'm relatively new to forte and I'd like to know how can you handle utility
type classes that you want to use through out your application? Ideally
what I want is a static class with static methods.
Let's say that I have a StringUtil class that has a bunch of methods for
manipulating strings.
My problem is that we have code that runs on the client and code that runs
on the server. Both areas could use the StringUtil class, but from what I
understand, I have to create StringUtil in a plan and then create a server
object of type StringUtil. The server object will eventually get assigned
to a partition. That's not good since I really want the server object to
physically reside at the server end and at the client end. (Actually, I
don't want a server object, I just want to invoke a static method of a
static class).
Any clues on how to solve this problem would be appreciated.
Also, what is the url at Sage-it that has a summary of all emails that have
been posted to [email protected]? Perhaps this question has been
answered previously.
Thanks in advance

Searchable thread archive <URL:http://pinehurst.sageit.com/listarchive/>Hi Richard,
Your question about "utility classes" brings up a number of issues, all of
which are important to long-term success with Forte.
There is no such thing as a static method (method that is associated with a
class but without an implicit object reference - this/self/me "pointer") in
TOOL, nor is there such thing as a global method (method not associated
with a class at all). This is in contrast to C++, which has both, and
Java, which has static methods, but not global classes. Frequently, Forte
developers will write code like this:
result, num : double;
// get initial value for num....
tmpDoubleData : DoubleData = new;
tmpDoubleData.DoubleValue = num;
result = tmpDoubleData.Sqrt().DoubleValue;
tmpDoubleData = NIL; // send a hint to the garbage collector
in places where a C++ programmer would write:
double result, num;
// get initial value for num....
result = Math::Sqrt(num);
or a Java programmer would write:
double result, num;
// get initial value for num....
result = Math.sqrt(num);
The result of this is that you end up allocating an extra object now and
then. In practice, this is not a big deal memory-wise. If you have a
server that is getting a lot of hits, or if you are doing some intense
processing, then you could pre-allocate and reuse the data object. Note
that optimization has its own issues, so you should start by allocating
only when you need the object.
If you are looking for a StringUtil class, then you will want to use an
instance of TextData or TextNullable. If you are looking to add methods,
you could subclass from TextNullable, and add methods. Note that you will
still have to instantiate an object and call methods on that object.
The next issue you raise is where the object resides. As long as you do
not have an anchored object, you will always have a copy of an object on a
partition. If you do not pass the object in a call to another partition,
the object never leaves. If you pass the object to another partition, then
the other partition will have its own copy of the object. This means that
the client and the server will have their own copies, which is the effect
you are looking for.
Some developers new to Forte will try to get around the lack of global
methods in TOOL by creating a user-visible service object and then calling
methods on it. If you have a general utility, like string handling, this
is a bad idea, since a service object can reside only on a single
partition.
Summary:
* You may find everything you want in TextData.
* Unless you anchor the object, the instance will reside where you
intuitively expect it.
* To patch over the lack of static methods in TOOL, simply allocate an
instance when required.
Feel free to email me if you have more questions on this.

How do you Design and Develop?
How do you Design and Develop?
I know this varies based on alot of things such as knowledge, preference, purpose, resources, etc..but I am curious how different (level of expertise) designers actually prefer or implement their websites. I decided to do this post after two different forums discussions regarding 1.Templates and PHP and 2. Backend Development.
1. How do you generally approach a project?--Wireframe, Freehand (as it comes), PSD template, etc.--Do you have a specific 'methodology' or procedure?
2. What are 2-3 of your main resources / sites / applications etc that you use (and for what?)
Specifically: What do you use (and how) to get up a website? (I know again this depends on a variety of things, but in general..) *also if you would like to comment on your expertise or level maybe helpful.
Do you prefer (Pros/ Cons of:) What advice would you give regarding below?
Your own HTML/CSS/Script based site that you mostly (if not completley) built. (More control and original, but harder / tedious for beginner)
HTML Temlplate (tweak the HTML and CSS)--non framework type (Quick and easy, but usually poor quality, outdated?)--but some can servde as good starting point.
Wordpress (And others like Drupal, Joomla) (Somewhat quick and easy access to tweak a quality WP Theme with ability for alot of features--forms, search, databases, etc (otherwise might have trouble with advanced features w/o good working knowledge og PHP and MYSQL, maybe others?)--but kind of a 'workaround' for real HTML design?
Frameworks types like Foundation, Bootstrap, Skeleton
A combination or hybrid of methods? -- or another method I have overlooked?
Thanks very much for any insight you can offer, hopeully this will lead to a vibrant discussion.-The websites I build are 95% PHP/MySQL. They are heavy on business logic. I sometimes work with designers, SEO "experts" and (rarely) other coders. I almost never work on the content of websites. The clients do that themselves through the CMS I build for them.
I write every line of code myself except for the use of jQuery and a few PHP code classes adapted from others. I can build a complex website in a matter of minutes by reusing the code libraries and patterns I have developed from previous projects.
I don't use a PHP framework because I have developed my own "pseudo-framework" for the particular kinds of sites I build, but I respect the frameworks that are out there. They can teach you excellent coding habits.
In starting the design and logic of a site, the most essential question is: What is the website (or website project) supposed to accomplish? My clients tell me what they want to accomplish, but I usually decide how to get there. This holds for both business logic and design, because design also must serve the business objectives.
My website projects generally take four months to two years to complete. The client usually dedicates one employee to work as a liaison between me and the rest of the company. Because the sites I build are heavy on the business logic, a great deal of time is spent on testing and debugging. I make testing the responsibility of the client so I can't be held liable if, for instance, a terrible accounting mistake is discovered in the code logic.
I like to use Adobe Illustrator for design development because I became an Adobe Illustrator ACE in 2000; however, I can see that Fireworks is probably the better tool. Photoshop is an important secondary tool.
For general site management and code writing I use both Dreamweaver and ZEND Studio; however, I use Dreamweaver less and less.
I now require all my clients to have their websites (and also domain name registrations, since my company is a domain name reseller) hosted on my VPS server. This prevents anyone from stealing code I have worked for years to develop and also establishes a commitment between myself and the client. When you are starting a web development business, you can't demand this kind of commitment from the client. Even a lot of great seasoned developers can't. It depends on your reputation within the specific industry(ies) you service. -
How do you date and time stamp iCal entries? We share an event calendar and need to know when a new event was entered into iCal.
BKBK,
Thank you for your response. That does adequately cover the
client-originated sessions, but still leaves the ability I am
looking for unavailable.
It did serve to definitively answer my most pressing
question, however, with this statement:
Note: ColdFusion cannot create a session if an initiator
application uses a SendGatewayMessage method to start an
interaction with a client, such as an SMS user. In this case, the
sending code must keep track (for example, in a database) of the
messages it sends and their destinations. When a response event
arrives, it can look up the origniatorID to determine whether it
was in response to an outgoing message.
I will play around with the Application scope to see if there
might be a workable solution there.

How do you insert special characters with imovie 08?
How do you insert special characters into a project
with imovie 08?Don't think that would work. Since my "system date" is already set at 2007. I have 2 imports, one has the year as 2048, and the other at 2016!! I don't know where they are getting these dates from, but they are not the system date.
Were the files imported directly from a camcorder or from files already on your hard drive? In the first case the year may have been taken from the time "stamp" recorded when the footage was shot (which may or may not have been correctly set by the user). On the other hand, files imported from the hard drive seem to be keyed to the date the imported file is written to the "Events" folder which, of course, reflects the current system time/date setting. That's why I said you had to then import (re-import) the files from a hard drive source -- i.e., to ensure the DTG would be re-written. -
Where and how can I place and setup my airport to reduce EMF exposure?
I want to reduce EMF exposure from the Airport Time Machine which is sitting on my desk right now. Where and how can I place and setup it up?
What role does the TC have in your network?
If you do not want EMF (actually RF), exposure, move it as far as possible away. There is no rules.. but the inverse square law.. if you double the distance the radiation will drop by 4times. So for every double distance you drop RF by another 4times. Far more EMF is coming from the computer than the TC. So you should move that away as well if you are worried about EMF.
Let me also say, as doubtless others will, the RF exposure from TC or any wifi is tiny.
Firstly they do not continuously transmit.. it will pole briefly every few seconds but only will transmit during actual file transfer.
The power output of say a cordless phone is aprox 10x that of the TC. And that is or can be the same microwave freq as wifi or near to.
The mobile phone in your pocket is doing the same thing.
There is no proof that microwave radiation at such minute levels will do anything harmful.
If you have headaches etc which you believe are caused by wireless.. then do not use wireless.. turn it off and cable everything. Shield your house as well.
As a general principle.. shielding is effective.. If for instance you have a 27" imac on your desk.. place the TC on the wall behind the imac.. the metal of the imac will shield you to some extent.. although of course some radiation will bounce from other objects.
Any shielding of the TC will reduce its effective wireless range.. ie you can put the TC in a metal cage.. (look up Faraday Cage) which will stop all radiation.. If you open windows in the cage.. it should only get signal in those directions but it is not a neat easy rule. And obviously I can achieve the same thing by simply turning the wireless off.
The v5 utility has a control of power output on the TC.
This is just the same as distance.
Transmit power is able to be set to 10%, 25% and 50%. At the cost of range of course.
If you run Mountain Lion you will have to use tricks to load it.. but it can be done. Lion you can download it.

How do you backup and restore Boot Camp?
I thought I'd drop by and ask my perenial question: How do you backup and restore Boot Camp?
I'm running Windows 7 if it matters, on a MBPn 17 2010 core-i7 and my daughter will soon be running on a MBP 13 2011 core-i7.
I'm currently using SuperDuper! and Time Machine for the Mac side, and am backing up using Disk Utility capturing the entire Win7 partition but have no confidence that it will work if I restore it.
What does everyone here use, and have you successfully restored your Windows 7 environment?For me, Paragon Hard Disk Manager Suite 2011.
It contains Clone OS and other tools, for $49.
I'm not sure Paragon Backup is "Apple Boot Camp" friendly or not.
All available Paragon Hard Disk Management technologies are available in onesuite.
Hard Disk Manager Suite 2011
While lack of mention of Apple Boot Camp in System Backup may not be an issue, I have never used it. Paragon also has volume snapshot and other Mac OS tools - but then they are not all offered in a Suite to provide NTFS, HFS, Mac repair, etc.

Top 10 Apple Articles| Paragon Software Blog Apple Tips and Tricks
Lion will have to modify the partition tables to add its own Windows 7-ish system recovery partition, so I would definitely get a good backup strategy in place - and tested - ahead of time. Contrary to the "shouldn't have any impact" I always see an impact, and also re-initialize drives when a new OS comes out (though maybe wait for the .2 release). -
How do you unlock ipod touch security code
how do you unlock ipod touch security code
As far as I'm aware you're referring to the passcode. It seems that you've forgot the passcode that you've inserted, so your best bet is to connect your iPod to iTunes and have it restored back to factory settings. You'll be able to find the restore button by clicking on your iPod's name that's located right below the "Device's Tab."

As said above, you can click down, ons use the other finger to drag the object. I had turned on the setting to use three-finger drag, so you can drag objects with three fingers. To change gesture settings, go to the system preferences>trackpad. Here you can also see all of the gestures of Mac OS X.
