Hi,
I couldn't believe that you didn't get any warning so I did copy your
code into xcode. Voila, I do get warnings!
My suggestion is read again the comments carefully and check the
documentation.
It was mentioned before that [fh writedata ... needs a NSData ( or
NSMutableData ) and not a string.
Also check the docs for [NSFileHandle fileHandleForWritingAtPath:] it
needs a string. So fname should be a string.
You know that you can select the text in your code and then right/
control click to go to 'Find selected text.....'?
If you do then you can see that you need a NSString with the path and
not a URL.
Also don't forget, that if your file does not exist, *fh will be nil!!
Good luck.

Thanks, all for the responses.
First I changed the path to write to. The folder is writable. On
GetInfo for the folder "MYTEST", I have set "Read & Write"
permissions for:
You can, Owner, Group, & Others. Is there anything else I need to do
to make it write to that folder?
As a side note, I am running an Apache server on the mac I am
working on, and I can write PHP programs that will write to this
directory.
However, this is still not working. I am not getting anything under
"Errors and Warnings" in Xcode. Also the program loads. However,
after running the Debugger does come up.
On debugger there are 5 listed.
0. asm objc_msgSend 0x90a594c0:1
1. ?
2. asm -[NSConcreteFileHandle initWithPath:flags:createMode:]
0x92867509:1
3. asm +[NSFileHandle fileHandleForWritingAtPath:] 0x9287a5e6:1
4. THIS IS BROKEN DOWN IN SUB SECTIONS
[Arguments]
Value: 1
Variable: argc
Value: 0xbffffa5c
Variable: argv
[Locals]
Value: 0x2cf58
Variable: fname
Summary: {(int)[$VAR length]} bytes
Value: 0x1f4c
Variable: fh
Summary: file descriptor: {(int)[$VAR fileDescriptor]}
Here is the current code I am running:
/* START CODE */
#import <Cocoa/Cocoa.h>
int main(int argc, char *argv[])
{
NSData *fname = "file:///Users/cknorr/mytest/MYTEST/data.txt";
NSFileHandle *fh=[NSFileHandle fileHandleForWritingAtPath:fname];
[fh writeData:@"THIS IS A TEST"];
[fh closeFile];
return NSApplicationMain(argc, (const char **) argv);
}

Adding the @ just makes it an NSString constant...

still requires (NSData *), not (NSString *).
Argh! Or perhaps, given the nature of this error,
which I missed, I
should say "Arg!"
Surely you got a compiler warning? If you ignored
that, surely a
runtime error?
Check your errors, both at compile time and runtime
(and treat
warnings as errors).
Yeah... I was thinking the same thing... you /must/ have
got
warnings... eventually you would have gotten an Exception I
think :)
