Unfortunately there are many problems in your code. <ol> <li>The <code>C</code> function <a href="http://developer.apple.com/mac/library/documentation/Darwin/Reference/ManPages/man3/system.3.html" rel="nofollow noreferrer"><code>system</code></a> does not return the standard output of the script as <code>char*</code>.</li> <li>Even with a function which returns <code>char*</code>, you can't assign it to a array of <code>char</code> as you did: <pre><code> char* str="aeiou"; char foo[100]; foo[100]=str; /* doesn't work */ foo=str; /* doesn't work either */ </code></pre></li> <li>Cocoa's string class, <code>NSString*</code>, is not a C string <code>char*</code>, although you can easily convert between the two: <pre><code> NSString* str=[NSString stringWithUTF8String:"aeiou"]; </code></pre></li> </ol> If you want a string out of a call to an Apple script, you need to do the following: <ol> <li>Prepare an <a href="http://developer.apple.com/mac/library/documentation/Cocoa/Reference/Foundation/Classes/NSAppleScript_Class/Reference/Reference.html" rel="nofollow noreferrer"><code>NSAppleScript</code></a>: <pre><code>NSDictionary* errorDict; NSAppleScript* script=[[NSAppleScript alloc] initWithContentsOfURL:[NSURL fileURLWithPath:@"path/to/script" ] error:&errorDict]; </code></pre></li> <li>Execute and get a reply: <pre><code>NSAppleEventDescriptor* desc=[script executeAndReturnError:&errorDict]; NSString* result=[desc stringValue]; </code></pre></li> <li>Release the script: <pre><code>[script release]; </code></pre></li> </ol> Learn C & <a href="http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/ObjectiveC/Introduction/introObjectiveC.html" rel="nofollow noreferrer">Objective-C</a> and have fun!

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
