Xcode starter questions

So, I am wanting to get into programming with apps. I don't have any experience with programming with this kind of stuff. But my questions are: 1. Will Xcode work with Mac mini?
2. I hear that you have to pay a yearly $100 to apple to submit my apps to the App Store. Is this true and what are the likelihood a that I will be able to make enough to pay it plus profit?
3. Say I do charge for an app or built in feature, how will I receive my profit after apple takes their share?
4. How easy is Xcode to use? I understand that there is coding and I'm not sure how difficult that would be. I'm willing to learn.
5. What are the probabilities that I will get sales for charged apps I make? I know it's hard depending if the app is a hit or not but is like a ballpark estimate.
Thank you for any answers I'm wanting to look into this before I invest some money on this. If I have more questions ill post them below. Thanks!

do any of you know how to fix a problem i am having

Three Getting Started Questions with RV180

I recently purchased the RV180 router. I have a few quick "getting started" questions about using it:
1. Is the "Static DHCP" the screen I need to use in order to reserve DHCP addresses (see attached)? That's where I've been reserving all my DHCP addresses with. I'm just making sure I have the correct screen.
2. Do I need to do anything to "backup" my configuration, or will my settings still be around when the RV180 reboots?
3. Do I need to run a check for firmware update on the RV180, and how do I update the firmware on the RV180 (as well as the SG200-18), or does it usually come with the latest firmware out-of-the-box? If I go ahead and put a service contract on the RV180 and SG200-18, will I receive my firmware updates automatically? Are the part numbers for the service contracts the same for the RV180 and SG200-18?
Thanks!

Hello,
1. Is the "Static DHCP" the screen I need to use in order to reserve DHCP addresses (see attached)? That's where I've been reserving all my DHCP addresses with. I'm just making sure I have the correct screen.
Yes, that is the correct location to set DHCP reservations.
2. Do I need to do anything to "backup" my configuration, or will my settings still be around when the RV180 reboots?
Whenever you hit save after making a change you configuration is saved and will survive a reboot.
If you would like to save backup copy of your configration file just go to Administration >> Backup/Restore settings.
3. Do I need to run a check for firmware update on the RV180, and how do I update the firmware on the RV180 (as well as the SG200-18), or does it usually come with the latest firmware out-of-the-box? If I go ahead and put a service contract on the RV180 and SG200-18, will I receive my firmware updates automatically? Are the part numbers for the service contracts the same for the RV180 and SG200-18?
You will need to manually update the firmware on the RV180. That firmware is available here:
RV180 Firmware
It is simply one file, that you upload under Administration >> Firmware Upgrade. There is no bootcode for the routers (like there was with your switch)
You can locate this in the future the same way you did the SG200 firmware (because this link may change) on the Cisco website.
As for the service contract, the part number for both of those devices will be CON-SBS-SVC2.
Hope that helps, and I will try to get to your other questions sometime today as well. Also since you just bought there you are of course welcome to call in and get some support over the phone, both your devices do come with 1 year of technical support, and it sounds like you are getting or have contracts, so I guess make that 3 years.

Xcode newbee question

Hi I'm new to xcode programming. But I'm starting to build an application for mac using xcode.
I can get the application to work, but there are several questions that I cannot resolve by myself.
First of all, how can I make the application to be "Universal Binary"?
Also, when I use the Interface Builder, I make my own classes, say "MAfoo." And write it out to xcode. But after I write down the class codes and modify them in xcode, whenever I make changes to Interface Builder, how can I change the previous version of codes without overriding the codes that I have written.
I'm sorry if my question is vague.

Brian is correct that universal binary is the default for Xcode 3, but make sure you're using the Release build configuration. The Debug build configuration cannot build universal binaries.

You have to make the changes in Xcode. When you tell Interface Builder to write class files, it overwrites any existing class files.
A common situation is adding outlets and actions to your classes. What you have to do is open the header file in Xcode (MAfoo.h in your example) and add the outlets and actions. If you have your Xcode project open, the outlets and actions you added in Xcode will appear in Interface Builder.

Beginner XCode/Java Question - printf problem

Hello,
I have just started playing around with XCode and Java. I entered the statement:
System.out.printf("%s\n%s\n", "Welcome to", "Java Programming!");
into the default working java project (File -> New Project -> Java Tool) and Im getting the error "cannot find symbol" after I compiled it. I do not believe this is a syntax error since it was copied straight from a textbook. So, my questions are:
1. What "symbol" is Xcode refering to?
2. Does Xcode coem with the latest version of Java?
3. How can I check the Java version?
4. Is there a library that needs to be imported to get it working?
Thanks in advance!

Hi Arcus
I think you might have to change some of the Xcode settings to force it to use Java 1.5. Try this:
- From the menu, select: Project > Edit Active Target 'Your Program Name'
- From the popup window, select Settings > Simple View > Java Compiler Settings.
- Set Target VM Version and Source Version to 1.5
- Dismiss the window by clicking on the red dot at the top left corner.

Smart Start Question

I posted a question and received a reply regarding a Viper Smart Start and I have one additional question. I have an appointment to have a couple of problems addressed this weekend at another Best Buy and noticed another possible problem today.
I have always remote started when it was dark outside and the headlamps on auto so the headlights and parking lamps turn on when using the Viper. I started the Taurus today (daylight) to warm it after a recent snow and looked outside, no parking lamps on so I attempted to restart and still no parking lamps. After the third attempt to start I went out to the Taurus and it was running and probably started and shut down each time I used the Smart Start App.
Shouldn't the parking lamps be on when the car is running?

Yes. They definitely should be on while it is remote started. You definitely want to bring that up to the Autotechs when you take it back in.
While I am employed by Best Buy, all of my posts here are in a non-official capacity. Any information or recommendations that are given are done so in an attempt to help in any way that I can and are not an official part of my job. If you feel that I have helped, feel free to give me Kudos or mark my post as a solution...I like to know how well I am doing.

Starter question: ear created on sun one studio can't be redployed

Just start learning sun one studio. Followed the tutorial of helloworld, test succeed on sun one studio's RI server. I tried to redeploy the ear file on sun one's application 7, got error message:
Deployment Error -- Error while running ejbc -- Fatal Error from EJB Compiler -- -- Failed to load deployment descriptor for: hello cause: Error reading from file: C:\Sun\AppServer7\domains\domain1\server1\applications\j2ee-apps\hello_2\sun-EJBModule_Greeter.xml
under hello_2 folder, the applicaiton server unzipped descriptor is named: EJBModule_Greeter.xml.
shouldn't the ear file be able to redeploy without modification on any J2EE complied application server? what did I do wrong?
Thanks for your help.
regards.

I'll answer my own question - for anyone else who may want to know. The tool is SUN ONE Migration tool for application servers, and it can be found at URL http://www.sun.com/migration/sunonetools.html.
The migration is from J2EERI to S1AS. I haven't tried it out yet , but will soon.
Earlier I asked ...
Do I understand correctly - I must use a migration
tool to migrate from SUN ONE to SUN ONE?

Getting started question

I'm sure I'll have fewer questions as times moves on, but here is another newbie question.
I've gone through the initial getting started chapter on the 'Calculator' stateless session bean J2EE project.
At the step:
<i>Deploying and Running the Calculator Application</i>
I think I successfully deploy my EAR.
The page won't load in my browser.
I've tried many flavors of localhost, localhost.corp.adobe.com, AHAMILTO1-XP and AHAMILTO1-XP.corp.adobe.com to port 50418/Calculator/Calculator.jsp.
For example:
http://localhost:50418/Calculator/Calculator.jsp
Am I using the wrong port? Is the port 50418 not an http port? I guess I'm asking how do I determine my http port number? I also tried 50000.
I get the response during deployment:
<i>Jan 11, 2005 2:27:57 PM /userOut/deploy (com.sap.ide.eclipse.sdm.threading.DeployThreadManager) [Deploy Thread] INFO:
CalculatorEar.ear -> Successfully deployed file:/C:/DOCUME1/ahamilto/LOCALS1/Temp/temp54088CalculatorEar.ear
DEPLOYMENT ...
==> SDM host : AHAMILTO1-XP
==> SDM port : 50418
==> URL : file:/C:/DOCUME1/ahamilto/LOCALS1/Temp/temp54088CalculatorEar.ear
... FINISHED SUCCESSFULLY</i>

Hello,
1. Does your browser show the startpage of your local WAS if you try URL http://localhost:50000
2. Where does your port 50418 come from? It seams that you have several instances on your computer, maybe you should try http://localhost:50400/Calculator/Calculator.jsp to reach your application. XXX18 is normally the sdm port through which you deploy your application to j2ee engine.
Maybe that helps,
André

Xcode project questions

I have just created a new project in xcode.
Now,I would like to get rid of the files proj_Prefix.pch and projPriv.h , because i don't need them. However, it seems i can't just delete them, because otherwise xcode complains about not finding them.
In addition, can i get rid of the files projProj.xcconfig and projlTarget.xcconfig ?
Oh, and one more question: which files of xcode should i put into the SVN repository?
Thanks a lot in advance.
Gabriel.

You have to remove the proj_Prefix.pch and projPriv.h files from the project to delete them safely. In the project window, select the files you want to delete and press the Delete key. An alert opens asking you if you want to delete the references to the files or delete the files and references. Deleting the reference removes the file from the project but keeps it on your hard disk. Deleting the file and reference removes the file from the project and your hard disk. Deleting the reference, then moving the file to the Trash is safer than deleting the file and reference because you can recover the file if you find out you need it.
You can get rid of the xcconfig files. Those are Xcode configuration files that contain build settings. Configuration files are useful if you make a lot of changes to Xcode's default build settings. By putting the changed settings in a configuration file, you don't have to change the settings in Xcode for every project.
The point of a SVN repository is to track the changes you make to files. Put the files you need to track in the repository. At a minimum, you should put your source code files in the repository. What works for me is to put everything but the project's build folder in the repository. When I create a Xcode project I want to place under version control, I temporarily move the project's build folder. After importing the project into the repository and checking out the project's files, I move the build folder back with the project.

HT1695 i've recently got an iphone, and i did the starting questions i've connected to the wifi, but i won't activate. it also won't connect to itunes, please help

First things first, You need to update your wifi security settings. If its set at WEP, then change to WAP2. If its already set that way, then you need to make sure iTunes is up to date on your computer, then update your software.

Starter Question: how I can get faster the extansion of a file?

Hi all,
I'm a Java starter ... sorry for simple question ;-)
I use java.io.File and want to have the extension (suffix) of an file.
x is typ 'File' and I use x.list of a root directory. Now I want to check if the file is from typ *.exe.
My solution in moment is:
x.getAbsoluteFile().toString().toLowerCase().endsWith("exe")
This solution works, but I searching for an other solution because I think this one is very slow in runtime.
Can anyone help me?
cu
Stefan

This is the most efficient code I can make of it, but I can't see why this would be much faster than yours.import java.io.*;
public class Test {
    public static void main (String[] parameters) {
        File[] files = new File ("c:\\windows").listFiles ();
        for (int f = 0; f < files.length; f ++) {
            File file = files[f];
            if (! file.isDirectory ()) {
                String fileName = file.getName ();
                int lengthOfFileName = fileName.length ();
                if ((lengthOfFileName >= 4) && fileName.substring (fileName.length () - 4).equalsIgnoreCase (".exe")) {
                    System.out.println (file.getName ());
}Please show some respect to the people who tried to help you and do something with their advice.
Kind regards,

ITunes won't start--question a/b msconfig solution

Hi all,
I'm having the same problem as everyone else w/ regards to the iTunes not starting due to problem w/ QT not opening correctly. I tried the msConfig solution and it does work, but I have a question--is this allowing my computer to be susceptible to virueses? I tried to manually start my antivirus system (symantec) and it instantly closed down itunes.
Someone please help!

Thanks Harv55, but I have already done this twice and nothing happened...
I have even installed separately Quicktime but this didn't help either.

Xcode diverse questions.

Hello, looking to be a app developer, and I have a few questions about Xcode before I bug Apple. Xcode, as I am informed, runs on Panther, (beleive 1.5 does, or could you tell me the most recent one that will run on Panther? I know Panther is ancient, but thats what I'm running now on my old Powerbook, and I don't want to upgrade till I'm sure I'll be doing this. Also, could you tell me the main differeces between Xcode for Snow Leopard and Xcode for Panther? Thanks alot.

I would like to tell you definitively the most recent version of Xcode that will run on 10.3, but Apple's "All downloads" site for developers is down right now. I think it is 2.2 or maybe 2.5. Regardless, there are extensive changes between the older Xcodes and Xcode4. Plus, the older Xcodes are from before Xcode development really "took off", so you will have a difficult time finding books or documentation. The hardest part is building the user interface with Interface Builder. That has changed several times over the years and when it says "control-drag from X outlet to Y object" you may be lost if you don't have the exact version of Xcode that matches whatever tutorial you are using.
There is quite a bit of information available for Xcode3, but Xcode4 has now been released and that is another significant change. The differences are primarily platforms and Interface Builder. Older Xcodes only support Mac development for PPC. Xcode3 can build software for iOS, PPC and Intel Macs, and is a pretty good stand-alone IDE. Xcode4 is focused on iOS and Snow Leopard Intel Macs.

Xcode debugger question

How do i setup the debugger in xcode?

The debugger is already setup in Xcode, do you have a specific question?

Remote start question

Does anyone make a remote start with a learning remote, or have remotes that have factory codes built in? I want to buy one for my 1998 Ford Escort wagon, and I figured if someone made one it would be a lot less wiring involved if the remote could learn the codes for the door lock/unlock, and trunk release. I understand that most units have these features but you have to wire the "brain" into the wiring harness for this to work. I'll be working outside on this, this car is a "beater", and I really don't want to take the time to wire those functions in if I can use the factory hardware and use a remote with the factory codes in it.
Thanks,
Snyde

Hi snydley100,
I like the idea but I don't see anything like that that we currently carry. I'm hoping some of our Super Users that a more versed in Remote Starts will offer their thoughts. I will also check around to see if anyone's familiar with this. You might also want to stop in and talk to the install bay techs. They might have some ideas on this as well.
Thank you,
