  • How do I track down the source of a KVC exception: this class is not key value coding-compliant for

    - by sam
    I get this error when I try to run my app: 2010-04-29 13:49:01.355 MyApp[56123:207] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<MyViewController 0x5112b10> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key toolbar.' MyViewController used to have an IBOutlet called 'toolbar' that connected to a UIToolbar object in a nib. I decided I no longer needed the toolbar or the nib so I removed them from the project. But Xcode seems to still want to refer to 'toolbar'. Where might the reference to toolbar be if I no longer use a nib? I can synthesize a dummy 'toolbar' property to appease Xcode, but I want to avoid this kind of ugly hack.

  • How to skip all the column names in MySQL when the table has auto increment primary key?

    - by Jian Lin
    A table is: mysql> desc gifts; +---------------+-------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +---------------+-------------+------+-----+---------+----------------+ | giftID | int(11) | NO | PRI | NULL | auto_increment | | name | varchar(80) | YES | | NULL | | | filename | varchar(80) | YES | | NULL | | | effectiveTime | datetime | YES | | NULL | | +---------------+-------------+------+-----+---------+----------------+ the following is ok: mysql> insert into gifts -> values (10, "heart", "heart_shape.jpg", now()); Query OK, 1 row affected (0.05 sec) but is there a way to not specify the "10"... and just let each one be 11, 12, 13... ? I can do it using mysql> insert into gifts (name, filename, effectiveTime) -> values ("coffee", "coffee123.jpg", now()); Query OK, 1 row affected (0.00 sec) but the column names need to be all specified. Is there a way that they don't have to be specified and the auto increment of primary key still works? thanks.

  • MSSQL: Primary Key Schema Largely Guid but Sometimes Integer Types...

    - by Code Sherpa
    OK, this may be a silly question but... I have inherited a project and am tasked with going over the primary key relationships. The project largely uses Guids. I say "largely" because there are examples where tables use integral types to reflect enumerations. For example, dbo.MessageFolder has MessageFolderId of type int to reflect public emum MessageFolderTypes { inbox = 1, sent = 2, trash = 3, etc... } This happens a lot. There are tables with primary keys of type int which is unavoidable because of their reliance on enumerations and tables with primary keys of type Guid which reflect the primary key choice on the part of the previous programmer. Should I care that the PK schema is spotty like this? It doesn't feel right but does it really matter? If this could create a problem, how do I get around it (I really can't move all PKs to type int without serious legwork and I have never heard of enumerations that have guid values)? Thanks.

  • Why can I create a table with PRIMARY KEY on a nullable column?

    - by AlexKuznetsov
    The following code creates a table without raising any errors: CREATE TABLE test( ID INTEGER NULL, CONSTRAINT PK_test PRIMARY KEY(ID) ) Note that I cannot insert a NULL, as expected: INSERT INTO test VALUES(1),(NULL) ERROR: null value in column "id" violates not-null constraint DETAIL: Failing row contains (null). ********** Error ********** ERROR: null value in column "id" violates not-null constraint SQL state: 23502 Detail: Failing row contains (null). Why can I create a table with a self-contradictory definition? ID column is explicitly declared as NULLable, and it is implicitly not nullable, as a part of the PRIMARY KEY. Does it make sense? Edit: would it not be better if this self-contradictory CREATE TABLE just failed right there?

  • Using Rails, how can I set my primary key to not be an integer-typed column?

    - by Rudd Zwolinski
    I'm using Rails migrations to manage a database schema, and I'm creating a simple table where I'd like to use a non-integer value as the primary key (in particular, a string). To abstract away from my problem, let's say there's a table employees where employees are identified by an alphanumeric string, e.g. "134SNW". I've tried creating the table in a migration like this: create_table :employees, {:primary_key => :emp_id} do |t| t.string :emp_id t.string :first_name t.string :last_name end What this gives me is what seems like it completely ignored the line t.string :emp_id and went ahead and made it an integer column. Is there some other way to have rails generate the PRIMARY_KEY constraint (I'm using PostgreSQL) for me, without having to write the SQL in an execute call? NOTE: I know it's not best to use string columns as primary keys, so please no answers just saying to add an integer primary key. I may add one anyway, but this question is still valid.

  • Running emacs in GNU Screen overrides .emacs settings for [home] key binding in FreeBSD 8.2

    - by javanix
    If I use the following .emacs file, I am able to go to the beginning/end of the current line using the home/end keys as I would expect. (keyboard-translate ?\C-h ?\C-?) (add-to-list 'load-path "/home/sam/programs/go/go/misc/emacs/" t) (require 'go-mode-load) (global-set-key [kp-home] 'beginning-of-line) ; [Home] (global-set-key [home] 'beginning-of-line) ; [Home] (global-set-key [kp-end] 'end-of-line) ; [End] (global-set-key [end] 'end-of-line) ; [End] However, if I open up a screen session it does not function like this (the [home] key still brings me to the beginning of the buffer for some reason). Here is my .screenrc file if anyone can spot anything funky in there: term xterm defutf8 on defflow off startup_message off # terminfo and termcap for nice 256 color terminal # allow bold colors - necessary for some reason attrcolor b ".I" # tell screen how to set colors. AB = background, AF=foreground termcapinfo xterm 'Co#256:AB=\E[48;5;%dm:AF=\E[38;5;%dm' #use bash as the default login shell defshell -bash

  • Refurbished System Windows License Key and OEM Media

    - by Timothy R. Butler
    According to this question, it is legal to use a Windows 7 OEM license that is presently installed as a 32-bit install with a 64-bit version of Windows 7. With that in mind, I purchased several refurbished systems through TigerDirect. When I received the computers today, I found that they have a Windows 7 license key attached to them that says it is a "refurbished key." A flyer in the box also seemed to imply that this key would not work with regular OEM media. Has anyone tried using regular OEM media with a refurbished key? I had hoped to create a new 64-bit WIM image that I could use on these systems, but I don't want to try replacing the default install with this new 64-bit install only to find that the key won't validate. If it requires a special customized image, is it possible to convert another type of Windows 7 disc into the required sort much as one can convert a retail disc to an OEM one (and vise versa)?

  • Compose key on Windows

    - by Craig McQueen
    On Linux, the Compose key is a great way to enter many symbols. E.g. m-dash — by pressing Compose then --- ö by pressing Compose then :o Euro € by pressing Compose then C= (The Compose key function can be assigned to various keyboard keys, such as right/left Alt, right/left Windows key.) I really miss the Compose key when using Windows. I've looked but so far haven't found any way to get equivalent Compose key functionality on Windows. Does anyone know of how to do it?

  • Find the product key I entered for MS Office on Mac

    - by Rick Reynolds
    I have several legal license keys for Office:mac 2008. I want to do a quick audit of the two machines I've installed office on and verify which license keys are being used where. But I don't see the license key anywhere on the about dialog (or elsewhere). I've seen other postings on the 'net directing me to look at various .plist files, but those only give me the "Product ID" which is different from the license key (which MS calls the "Product Key" on the little sticker). Is there a way outside of calling MS to correlate the Product Key (which is required for installation and is the real license key) to the Product ID I see in the app itself?

    I bought a Gandi.net SSL certificate and I'm following this tutorial. I created the key file. then transformed it to CSR then added it to Gandi website and waited for the CRT. then removed the password from the key === result : [FINAL KEY] then merged the CRT and the FINAL KEY into one file == result : [FINAL PEM] then heroku ssl:add final_pem final_key --app app_name and... got Pem is invalid / Key doesn't match the Pem certificate. I tried 3 times and I really don't know what's going one. Can you help ?

  • SSH use only my password, Ignore my ssh key, don't prompt me for a passphrase

    - by Stefan Lasiewski
    This is a question regarding the OpenSSH client on Linux, MacOSX and FreeBSD. Normally, I log into systems using my SSH key. Occasionally, I want my SSH client to ignore my SSH key and use a password instead. If I 'ssh hostname', my client prompts me for the Passphrase to my SSH key which is an annoyance. Instead, I want the client to simply ignore my SSH key, so that the server will ask me for my password instead. I tried the following, but I am still prompted for the passphrase to my SSH key. After this, I am prompted for my password. ssh -o PreferredAuthentications=password host.example.org I want to do this on the client side, without any modification of the remote host.

  • Known Hosts ECDSA Host Key Multiple Domains on One IP

    - by Jonah
    Hello, world!, I have a VPS set up with multiple domain names pointing to it. Arbitrarily, I like to access it via SSH through the domain name I'm dealing with. So for example, if I'm doing something with example1.com, I'll log in with ssh [email protected], and if I'm working with example2.com, I'll log in with ssh [email protected]. They both point to the same user on the same machine. However, because SSH keeps track of the server's fingerprint, it tells me that there is an offending host key, and makes me confirm access. $ ssh [email protected] Warning: the ECDSA host key for 'example2.com' differs from the key for the IP address '123.123.123.123' Offending key for IP in /home/me/.ssh/known_hosts:33 Matching host key in /home/me/.ssh/known_hosts:38 Are you sure you want to continue connecting (yes/no)? Is there a way to ignore this warning? Thanks!

  • Remap Apple MacBook Eject key in Windows?

    - by user1238528
    I have a MacBook with Windows 7 on it as my daily driver. My MacBook has a nearly useless Eject key, but I wish it was a forward delete key. KeyRemap4Macboook works great in OS X. Is there any software that is equivalent in Windows? I have tried KeyTweaks and HotKeys and neither of them will recognize the Eject key. I looked it up and I think it is key 161. Is there any way to make the key into a more useful forward delete? Could I just go into the registry and do it that way?

  • Enter / Return key stops working

    - by andygrunt
    I have a Dell Latitude E5400 laptop running Windows 7. Everything runs fine on it for days then I suddenly notice the enter/return key is no longer working e.g. I could be writing an email, press enter for a new line but it doesn’t ‘register’ – so no new line. I thought it might be some dirt under the key perhaps so I tried running the Windows onscreen keyboard but the Enter key on that doesn’t work either. A reboot always fixes the problem but it’s a pain. Any ideas a) how to fix it and b) out of interest, is there some other key combination that I can use as an alternative to using the Enter key when I need to?

  • sudo su - username while keeping ssh key forwarding

    - by Florian Schulze
    If I have a server A into which I can login with my ssh key and I have the ability to "sudo su - otheruser", I lose key forwarding, because the env variables are removed and the socket is only readable by my original user. Is there a way I can bridge the key forwarding through the "sudo su - otheruser", so I can do stuff on a server B with my forwarded key (git clone and rsync in my case)? The only way I can think of is adding my key to authorized_keys of otheruser and "ssh otheruser@localhost", but that's cumbersome to do for every user and server combination I may have.

  • Cannot use `su` or `sudo` after set up key-based access to SSH

    - by OrangeTux
    I'm following this tuturial to setup key-based access to the SSH I created a user. I add copy the key to the client via ssh-copy-id <username>@<host> Becasuse ssh <username>@<host> still prompts for a password I run ssh-add on the local machine. The terminal doens't prompt for a password, I can login without using a password. But I cannot run su anymore. Every input for the password results in Authentication failure. I tried it again. But before coping the key, I added to the sudoer file. Copied key, ssh-add. But now I cannot login to my SSH shell att all? How can I setup a key-based SSH access with the possibiluty to use su or sudo?
