    <p>Hi my english is not very good, so i'll try my best to explain my problem I'm new with cocoa and xcode so maybe my problem is easier than i think</p> <p>I have class , that's basically is a formulary for register client information, there i defined a method - (void)searcht:(NSString*)s; this method make a query to the database where the code = s</p> <pre><code>- (void) searcht:(NSString *)s{ PGSQLConnection *connection1= [[PGSQLConnection alloc] init]; NSString *cmd=[[NSString alloc] initWithFormat:@"select * from oc_master_customer where customer_id=%@",s ]; NSLog(@"%@", cmd); if ([connection1 connect]){ NSLog(@" ENTRO %@", [connection1 lastError]); PGSQLRecordset *rs1 = [connection1 open:cmd]; if (![rs1 isEOF]) { NSLog(@" ENTRO 2 %@", [connection1 lastError]); [matchcode setStringValue: [[rs1 fieldByName:@"matchcode"] asString]]; NSLog(@" MATCHCODE %@", [matchcode stringValue]); NSLog(@" MATCHCODE 2 %@", [[rs1 fieldByName:@"matchcode"] asString]); [name1 setStringValue: [[rs1 fieldByName:@"name1"] asString]]; [zip setStringValue: [[rs1 fieldByName:@"zip"] asString]]; [bank_code setStringValue: [[rs1 fieldByName:@"bank_code"] asString]]; [bank_account setStringValue: [[rs1 fieldByName:@"bank_account"] asString]]; [bank_name setStringValue: [[rs1 fieldByName:@"bank_name"] asString]]; [bank_iban setStringValue: [[rs1 fieldByName:@"bank_iban"] asString]]; [bank_swift setStringValue: [[rs1 fieldByName:@"bank_swift"] asString]]; [city setStringValue: [[rs1 fieldByName:@"city"] asString]]; [city_part setStringValue: [[rs1 fieldByName:@"citypart"] asString]]; [street setStringValue: [[rs1 fieldByName:@"street"] asString]]; [country setStringValue: [[rs1 fieldByName:@"country_code"] asString]]; } [connection1 close]; [rs1 close];} } </code></pre> <p>I use this method with a NSSearchfield and it worked perfectly, now i made a subclass of nsearchfield and i want to call this method when the user pressed enter, i could access to the method but i can't change the string values from the IBOutlets. I already have declared the IBOutlets as @public. My code from the nssearchfiel subclass </p> <pre><code>-(void)keyUp:(NSEvent*)event { if ([event keyCode]==36){ [[self window] selectKeyViewFollowingView:self]; customers* c= [[customers alloc] init]; NSLog(@"Key released: %@",[self stringValue]); [c searcht:[self stringValue]]; } } </code></pre> <p>My problem is that the method i defined doesn't do a thing if i called from other class somebody have an idea of that what i have to do or i missing</p>

    1. COIt would be helpful if you could reformat your code to make it more readable. Also, I don't quite understand the problem you're having. Could you please point out what in your sample code is not working properly? To be specific, can you remove the code that's working, to make it clearer what's not?

    2. COmy code works aat but, when i called the method that i defined in customers.m from my subclass searchfield.m it can't change the string values from the IBoutlets defined in customers.h so i guess i'm missing something important about the inherince

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.
