XCode 3.0 C++ cout/cin Question

When I was writing programs on 10.4 version of XCode, I could type something like:
cout << n << endl;
cin >> n;
and not get an error, but now that I'm running the 10.5 version of XCode, I have to type:
std::cout << n << std::endl;
std::cin >> n;
everytime. It doesn't matter if I include stdlib.h or cstdlib, I'll always get an error if I don't type that std::. Can somebody tell me why, and how can I get it back to the other way?

That is the C++ language. You must have been using some really old headers and/or GCC 3 on 10.4.
What you want to do is:
#include <iostream>
using namespace std;

Compiled Error in Xcode for iphone game and other questions

Dear all,
Hi, I am a newbie of xcode and objective-c and I have a few questions regarding to the code sample of a game attached below. It is written in objective C, Xcode for iphone4 simulator. It is part of the code of 'ball bounce against brick" game. Instead of creating the image by IB, the code supposes to create (programmatically) 5 X 4 bricks using 4 different kinds of bricks pictures (bricktype1.png...). I have the bricks defined in .h file properly and method written in .m.
My questions are for the following code:
- (void)initializeBricks
brickTypes[0] = @"bricktype1.png";
brickTypes[1] = @"bricktype2.png";
brickTypes[2] = @"bricktype3.png";
brickTypes[3] = @"bricktype4.png";
int count = 0;`
for (int y = 0; y < BRICKS_HEIGHT; y++)
for (int x = 0; x < BRICKS_WIDTH; x++)
- Line1 UIImage *image = [ImageCache loadImage:brickTypes[count++ % 4]];
- Line2 bricks[x][y] = [[[UIImageView alloc] initWithImage:image] autorelease];
- Line3 CGRect newFrame = bricks[x][y].frame;
- Line4 newFrame.origin = CGPointMake(x * 64, (y * 40) + 50);
- Line5 bricks[x][y].frame = newFrame;
- Line6 [self.view addSubview:bricks[x][y]]
1) When it is compiled, error "ImageCache undeclared" in Line 1. But I have already added the png to the project. What is the problem and how to fix it? (If possible, please suggest code and explain what it does and where to put it.)
2) How does the following in Line 1 work? Does it assign the element (name of .png) of brickType to image?
brickTypes[count ++ % 4]
For instance, returns one of the file name bricktype1.png to the image object? If true, what is the max value of "count", ends at 5? (as X increments 5 times for each Y). But then "count" will exceed the max 'index value' of brickTypes which is 3!
3) In Line2, does the image object which is being allocated has a name and linked with the .png already at this line *before* it is assigned to brick[x][y]?
4) What do Line3 and Line5 do? Why newFrame on left in line3 but appears on right in Line5?
5) What does Line 4 do?
Thanks

Hi North -

UIImage *image = [ImageCache loadImage:brickTypes[count++ % 4]]; // Line 1
The compiler is telling you it doesn't know what ImageCache refers to. Is ImageCache the name of a custom class? In that case you may have omitted #import "ImageCache.h". Else if ImageCache refers to an instance of some class, where is that declaration made? I can't tell you how to code the missing piece(s) because I can't guess the answers to these questions.
Btw, if the png file images were already the correct size, it looks like you could substitute this for Line 1:
UIImage *image = [UIImage imageNamed:brickTypes[count++ % 4]]; // Line 1
2) How does the following in Line 1 work? Does it assign the element (name of .png) of brickType to image?
brickTypes[count ++ % 4]
Though you don't show the declaration of brickTypes, it appears to be a "C" array of NSString object pointers. Thus brickTypes[0] is the first string, and brickTypes[3] is the last string.
The expression (count++ % 4) does two things. Firstly, the trailing ++ operator means the variable 'count' will be incremented as soon as the current expression is evaluated. Thus 'count' is zero (its initial value) the first time through the inner loop, its value is one the second time, and two the third time. The following two code blocks do exactly the same thing::
int index = 0;
NSString *filename = brickTypes[index++];
int index = 0;
NSString *filename = brickTypes[index];
index = index + 1;
The percent sign is the "modulus operator" so x%4 means "x modulo 4", which evaluates to the remainder after x is divided by 4. If x starts at 0, and is incremented once everytime through a loop, we'll get the following sequence of values for x%4: 0, 1, 2, 3, 0, 1, 2, 3, 0, 1, ...
So repeated evaluation of (brickTypes[count++ % 4]) produces the sequence: @"bricktype1.png", @"bricktype2.png", @"bricktype3.png", @"bricktype4.png", @"bricktype1.png", @"bricktype2.png", @"bricktype3.png", @"bricktype4.png", @"bricktype1.png", @"bricktype2.png", ...
3) In Line2, does the image object which is being allocated has a name and linked with the .png already at this line *before* it is assigned to brick[x][y]?
Line 2 allocs an object of type UIImageView and specifies the data at 'image' as the picture to be displayed by the new object. Since we immediately assign the address of the new UIImageView object to an element of the 'bricks' array, that address isn't stored in any named variable.
The new UIImageView object is not associated with the name of the png file from which its picture originated. In fact the UIImage object which inited the UIImageView object is also not associated with that png filename. In other words, once a UIImage object is initialized from the contents of an image file, it's not possible to obtain the name of that file from the UIImage object. Note when you add a png media object to a UIImageView object in IB, the filename of the png resource will be retained and used to identify the image view object. But AFAIK, unless you explicitly save it somewhere in your code, that filename will not be available at run time.
4) What do Line3 and Line5 do? Why newFrame on left in line3 but appears on right in Line5?
5) What does Line 4 do?
In Line 2 we've set the current element of 'bricks' to the address of a new UIImageView object which will display one of the 4 brick types. By default, the frame of a UIImageView object is set to the size of the image which initialized it. So after Line 2, we know that frame.size for the current array element is correct (assuming the image size of the original png file was what we want to display, or assuming that the purpose of [ImageCache loadImage:...] is to adjust the png size).
Then in Line 3, we set the rectangle named newFrame to the frame of the current array element, i.e. to the frame of the UIImageView object whose address is stored in the current array element. So now we have a rectangle whose size (width, height) is correct for the image to be displayed. But where will this rectangle be placed on the superview? The placement of this rectangle is determined by its origin.
Line 4 computes the origin we want. Now we have a rectangle with both the correct size and the correct origin.
Line 5 sets the frame of the new UIImageView object to the rectangle we constructed in Lines 3 and 4. When that object is then added to the superview in Line 6, it will display an image of the correct size at the correct position.

CIN Question

We produce product A in India,We sell this product A to customers in different tradenames (B, C and D).
According to our Indian business there is "legal" requirement to have 1=1 match for product name (production-sell).
Can you check if there have been similar issues with your previous SAP/CIN implementations in India and what has been the solution?
Can we for example modify our CIN reports or use some other approach in official reporting to show that our production material description matches our sales description.
Please Advise
Regards,
Raj

The options are as below:
1. Maintaining the same material code, also maintain Customer Material Info Record in Transaction VD51. In Customer Material Info Record, maintain in description the material code / description which is customer specific. This is ideal, as it is your books of accounts for accounting and excise purpose.
2. If you want to reflect the material as separate material, maintain the same as separate Material Code. In this scenario, you may at times require to move stock from one code to another, which should be possible through MM Module.
I have followed option 1 in our implementations for such requirements.

Question about 'cin' & 'cout' (C++) (SOLVED)

Probably a stupid question with a simple answer but here goes;
when i compile the following code
#include <iostream>
#include <string>
int main(int argc, char* argv[])
string buffer;
while (1 == 1)
cout<<" ## ";
cin>>buffer;
it compiles fine, when run it does the following
prints " ## " minus quotes
then pauses for input
however the strange thing is that if i enter a string with a space in, quotes or no, it repeats the 'cout' statement, see below for output
## this is a string
then pauses for input, as it should, i ask you why it does this as i don't call it "expected behaviour", not with that code anyway.
EDIT: fixed some typos
EDIT_2: boxed of output&code, thx ewaller

Nah, there is a loop, right?
You type "this is a string".
cin reads "this" and gets out.
while(1 == 1) is tested and gets in (of course).
cout prints " ## ". (*)
cin reads "is" and gets out.
etc.
(*) The thing why it gets "mixed" (I mean you type the whole string and then ## * 4 appears) is probably because terminal is flushing (and thus refreshing) stdout on Enter hit only.

Xcode debugger question

How do i setup the debugger in xcode?

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

Universal CINs? (For MacOS 10.4 and Intel Macs)

Hi!
1. I was wondering if it was possible to build a Universal CIN for MacOS 10.4, in order to support Intel Macs. If so how? I get link errors in Xcode because it cannot find CIN functions such as MoveBlock, and NumericArrayResize when compiling for i386 (which is understandable). Is there an Intel Mac version of liblabviewcin.a and liblvexports.a?
2. Is it possible for LabVIEW to call a DLL function in a Universal framework? Or must all frameworks be for the PowerPC?
Thanks.

I am trying to invoke code external to LabVIEW that contain AltiVec and in the future, SSE instructions. Right now I am trying to bundle PowerPC code (with AltiVec instructions) with Intel i386 code to support both PowerPC and Intel Macs using a single binary.
So basically I have:
1. A CIN that uses AltiVec currently (which includes AltiVec instructions). I would prefer that it switched to a SSE version automatically when I call the CIN on an Intel Mac.
2. Some VIs that uses the Call Library Function Node to invoke a function in a Universal Framework. The framework is compiled for both PowerPC and Intel. The PowerPC version includes AltiVec instructions and thus is incompatible with Rosetta. I was wondering if LabVIEW would actually be able to invoke such a function successfully on an Intel Mac. I don't have an Intel Mac on hand, which is why I am asking.
PS: The original post was posted using NI JT's account accidentally. The question is actually mine.

How to view C/C++ pointer as an array in Xcode GUI debugger?

How to view C/C++ pointer as an array in Xcode GUI debugger?

A similar question was asked recently regarding strings. You cannot pass pointers in LabVIEW as you do in C. You can pass an array to a DLL, but that means you would need to write a wrapper DLL. Be sure to read the section in the LabVIEW Help on calling code from text-based languages and also take a look at the "Call DLL" example that ships with LabVIEW - it contains many examples of how to deal with various datatypes.

Learn C on the mac questions...

Hello everybody,
I'm just starting to learn programming. I choose to start with the book Learn C on the Mac - Dave Mark.He wrote the book while using xCode 3.1
I have 2 questions.
First: Every Project that came with the book, when i try to open one in xcode after build and run it brings the error "There is no SDK with the name or path 'macosx'
Second: The book talks about Syntax and Semantic errors and how to produce then to learn from it so suppose to apperar something like "error: syntax error before '{' token" but Xcode only give me "Expected indentifier or '('
Are those because my version of Xcode (3.2.2) or I'm doing something wrong?
I will appreciate your answers and comments.
Thanks

Your first problem is caused by the book projects using an older version of the Mac OS X SDK that you do not have installed on your Mac. The fix is to set the Base SDK for the projects to one that is installed on your Mac. In Xcode 3.2 choose Project > Edit Project Settings to open the project inspector. Select the General tab in the inspector. Use the Base SDK for All Configurations menu in the inspector to set the SDK. You should set it to Mac OS X 10.6.
Regarding your second question, I would not worry about the compiler error message not matching exactly what the book says. What is important to know that you have a syntax error, why you have one, and how to correct it. I assume the book explains the why and how.

MAS xCode and Developer xCode

I have a 99 dollar a year dev license and can receive xCode for free, but even though I am signed into the same Apple ID, the xCode program in MAS still shows as being $4.99.
In the hopes of being able to consolidate my future updates and updating processes for xCode and SDK's using MAS instead of manually downloading from the dev site, I clicked on the "buy it" button. My Mac then began downloading xCode through MAS even though I already had the latest version of xCode installed.
Now to my questions, is this version of xCode going to overwrite my previous install even though it is the same version or will it install 2 instances (double disk space)? Does xCode from MAS include all the IOS and Mac SDKs, or are those only available through the dev download? And lastly is it possible to cancel a purchase in the MAS once it has been made, in case I can't just use MAS as my stand alone updater for xCode?

It appears from the comments to be the same app. This is a different distribution channel aside from the developer program. The only way to opt into the MAS is to buy. When I bought an update through the MAS for a product that I had earlier obtained from a different source it was replaced by the MAS version.
YMMV.

Japanese Character Display

Sorry for such a newbie question.
My program reads in a UTF-8 file containing some Japanese characters, stores them into a String variable and then attempts to print using: System.out.println(myString); . However, it doesn't display correctly in XCode or the Terminal (shows mostly question marks). When I follow it in the debugger, the Japanese characters show up correctly stored in the variable. Also, if I just do: System.out.println("japaneseCharacters"); where japaneseCharacters are actual japaneseCharacters, they print out correctly. I've made sure that my source files, the file being read in, and the terminal are both set to UTF-8. Can somebody point me in the right direction?
Thanks!

I believe yours is a application specific or platform specific problem.
when you write a code:
System.out.println("japaneseCharacters");what tool did you use? What is the locale setting of your platform?.
On our Linux platform, locale is ja_JP.UTF-8. So we need explicit charset argument
for encodings other than Japanese/UTF8 in using Java API classes and methods.
As many applications including editors rely on the locale ja_JP.UTF-8, we need special
configuration for handling other encodings as EUC-JP or Shift_JIS.

-verbose output on Windows

Hi all,
I've been working using JNI to call Java methods from a Windows command-line app, that's written in C++. Recently I've moved part of the application into a windows GUI app. I use the -verbose:jni option string to get the JVM jni debug output, in the command line tool, this appears on the console along with anything else that I printf with or whatever. Now that I am using a GUI app, there is no console available. I have tried creating a new console with AllocConsole() and tried remapping stdout, stdin, stderr, cout, cin, clog and cerr to the new console. I've tested this works using printf, fprintf(stdout, ...) and about every other combination that I can think of to print to the new console that I have created, and all of my output appears, however the -verbose output does not.
Does anyone know how to redirect this output to a new console (or just anywhere that I can read it). I've also tried calling System.setOut() etc. and pointed them to files. This lets me see things like the output from ExceptionDescribe(), but the -verbose output is still sadly missing.
Thanx,
Idries

Recently I've moved part of the application into a
windows GUI app. I use the -verbose:jni option string
to get the JVM jni debug output, in the command lineI have found no solution to this. I tried even redirecting stdout/stderr from C before loading the VM with the Invocation API. Even this did not work. Maybe you would have better luck with it.
Since I was only interested in GC messages the -Xloggc:filename option worked for me. But there is no -Xlogjni option unfortunately.
A last resort option is to download the JVM source, modify it to send -verbose output always to the vfprintf hook, and use Invocation API to set that. But you would have to rebuild the VM for that. You could always look through the source for clues. I suspect that the VM will use the vfprintf hook even on Windows if it cannot open stderr.

IOS 5.0 and iPhone along with "new user account"

I do hate this hacking aspect of all software, but with iTunes especially.
Earlier I tried to remove some duplicates in the iTunes on my old computer, but time after time they popped back from the trash can, what the heck!
There was a running computer with my iTunes account and everything was fine. Later I even made a restore to new phone after previous phone got lost.
Then I had to buy new laptop to replace the old as it got broken.
As instructed, I installed iTunes onto the new computer and was able to connect my Apple Store account and purchased Apps.
Then after I copied everything in the Apple Computer - folders and iTunes in my old (same user account name) to the new computer, now running with Windows 7 (former laptop had XP).
Now my iPhone 4 (iOS 5.0) does not sync.
Sync failed to start...
Also I wonder what is the reason not to be able to sync back from the handheld? Nokia has that and it really works. When I have new contacts and restore from backup I loose my contacts, since there is no sync file on the new computer. Why the system does not work automatically and sync back from the phone, if no source files found on the computer? The back sync coud be asked every time new phone or ipod/pad is connected.
Im starting to be absolutely fed up with this constant browsing through discussions forums and what ever hacking pages to get things running that I'm just about to throw the device into the lake next to my house. AAARGH!
Why do we even accept this? Who would buy or use a car, that had to be repaired or re-booted every 10 miles?
Great jobs!
