Maybe this is a very stupid question , but I am looking for a way to combine a string that doesn't change , and a varying string . I am making an update detection system for my app , and I would like it to say :
The newest version available is [and then the version number that is retrieved from the Internet .
I tried @"The newest version available is " + the dynamic string with the version number , but that didn't exactly work .
Can anybody help me ?

can't you do
<BLOCKQUOTE><font size="1"face="Geneva, Verdana, Arial">code:</font><HR><pre><font size=1 face=courier>
int ver_numb; <font color = brown>//Store your number here</font>
string text = <font color = red>"The newest version available is : "</font> + ver_numb
</font>[/code]
then display text?

That's what I'd do in Java

Thanks , but it didn't work . I do have another question now , though
How can you read a file from the Internet with AppleScript ?
What I would like to do is read the contents of a text file (http://homepage.mac.com/janvanboghout/versie.txt for example) and display that in a text view . Is that possible ?

Well, it's hard to know what will work unless we know what language you're using (*wink-wink*), but in AppleScript it would be:

<BLOCKQUOTE><font size="1"face="Geneva, Verdana, Arial">code:</font><HR><pre><font size=1 face=courier>set ver_numb to [whatever the version is]
set text to <font color = red>"The newest version available is : "</font> & ver_numb</font>[/code]

and in PHP/Perl it would be:

<BLOCKQUOTE><font size="1"face="Geneva, Verdana, Arial">code:</font><HR><pre><font size=1 face=courier>$ver_numb = [whatever the version is];
$text = <font color = red>"The newest version available is : "</font> . ver_numb;</font>[/code]

Note the period (.) in the PHP/Perl version...that's the string concatenation operator.[/LIST]

I don't think it is possible with just AppleScript unless you download the file and then read it from the .. but that isn't practical.

You'd need to use a cocoa method...

in your project, create a new header file and call it whatever you want like "fileGetter.h" then put in this info:

<BLOCKQUOTE><font size="1"face="Geneva, Verdana, Arial">code:</font><HR><pre><font size=1 face=courier>#import &lt;Foundation/Foundation.h&gt;


@interface fileGetter : NSObject {

}
+ (NSString *)getCode NSString *)path;
@end</font>[/code]

Then make a class file and call it whatever you want again like "fileGetter.m" and put in this:

<BLOCKQUOTE><font size="1"face="Geneva, Verdana, Arial">code:</font><HR><pre><font size=1 face=courier>#import <font color = red>"fileGetter.h"</font>


@implementation fileGetter
+ (NSString *)getCode NSString *)path {
return [NSString stringWithContentsOfURL:[NSURL URLWithString ath]];
}
@end</font>[/code]

Then from your applescript, you can use this code...

<BLOCKQUOTE><font size="1"face="Geneva, Verdana, Arial">code:</font><HR><pre><font size=1 face=courier>on clicked theObject
tell window of theObject
set theCont to (call method <font color = red>"getCode:"</font> of class <font color = red>"fileGetter"</font> with parameter <font color = red>"http:<font color = brown>//homepage.mac.com/janvanboghout/versie.txt"</font>)</font>
set theCont to theCont as string
set contents of text field <font color = red>"mySourceField"</font> to theCont
end tell
end clicked</font>[/code]

Works for me. BTW, someone else did the cocoa for me, I don't know anything I am using it for my forum viewer.

Thanks Synotic , I already found the Cocoa method on www.cocoadev.com , but I didn't know how to use the result in an AppleScript . This is exactly what I needed !

In Obj-C, check out

file:///System/Library/Frameworks/Foundation.framework/Versions/C/Resources/English.lproj/Documentation/Reference/ObjC_classic/Classes/NSMutableString.html

- (void)appendString NSString *)aString

appendString is your friend. You could do

NSMutableString *foo = [NSString stringWithString:@"current version is"];
NSString *version;
version = //some function call to get current version
[[foo appendString:@" "] appendString:version];

(the first string is to add a space in between)
