cocoa - In Xcode Document App: Why would init method of MyDocument be called twice? -

-

I followed Chapter 8 of the Pilgrim to implement the RaiseMan application. Then I decided to follow the same procedure to implement the code for practice in a coca programming class, which I am taking, but after the construction and running I got the following error message.

Object & lt; _NSControllerObjectProxy: 0x100460e30> Class _NSControllerObjectProxy

I do not know what this error message was, a few hits were made by searching Google, but their solutions seemed to be doing things I already did Was there.

I saw all the connections and assignments I made in the interface builder and nothing is clearly not seen wrong.

So I went to the debugger and set a breakpoint inside the Microsoft class init method and it is being said twice. How is this possible? What do I need to say init method twice for this? Stack trace shows that init is called from system functions which we have not written ourselves.

For comparison, I went back to the project that follows Chapter 8 of Hillegass and sets a breakpoint within the init method of MyDocument class, and it is being called once ( Which is what is expected).

BOOL object & lt; _NSControllerObjectProxy: 0x100460e30 & gt; Can not be made with class_NSControllerObjectProxy

It seems that you specify a BOOL property for an administrator, and a model key path Most of the time, you created one of the visual sections of cocoa, 'binding binding, such as enabled or editable .

You've forced to be enabled or editable , and make sure that they are all bound to the right model key path.

asp.net - Javascript/DOM Why is does my form not support submit()? -

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

I am trying to implement one for Delphi, but there are some problems with communication. Fitnesse will start my process, and give me a portmember as a command line argument. Then I should make a socket on the port number given to me, and fitness will connect to that port I am using a TCPCP server for the job: < Pre> TcpServer1.LocalPort: = ParamStr (ParamCount); TcpServer1 Active: = true; On OnEXEPT () -Event, I send the protocol version to use as specified in the protocol. Process TForm1.TcpServer1Accept (From: TOBject; ClientSocket: TCustomIpClient); Var s: ansistring; Start clientSocket. Syndrome ('slim - v 0.0', # 10); SetLength (S, 6); ClientSketts Receavebook (S, 6); End; When I call ReceiveBuf (), the process ends, and fitness throws an exception: java.net.SocketException: connection Reset I have seen what sent and received. It shows that my code sends the protocol version, fitness sends back a message, and when I try to get this message

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
