Workflow for writing ARM assembly code on the iphone -

-

I would like to start writing ARM codel and would like to run it on the iPhone

This release in the app store I do not intend to use the app to be in - originally I want to solve problems in using ARM and iPhone, just for hobbies and educational purposes

How do I do this Can I go I am not able to use any handwritten hand in the way of running a project.

I could not find any information about how to write an assembly code specifically for the iPhone , But as mentioned by other people here, you can either:

1) write inline AMM statement in C / C ++ / ObjC code, or 2) standalone in a 's file' Write assembly functions and simply add them to your XCode sources or 3) Standalone assembly function for an external sensor like NASM Kit. You write the assembly code in an '.s' file and use an '.o' object file from NSAM and link the object file to the xcode.

So if you want to write just a few assembly instructions then the inline assembler will be the easiest way, but if you plan to write several assembly tasks, then I would recommend a standalone assembly file and if If you plan to write several assembly tasks with macros and want cross-platform compatibility, then I will not add my assembly code to an object file. To Inserting images I suggest using NASM. Because I am using the XCode GCC assembler and it is significantly lower than NASM. You can get NASSM for free

Once you set your assembler environment, you will have to learn how to write an ARM assembly code! Because iPhones (and many other portable devices and smartphones) use the ARM instruction set. Very good but old introduction to the ARM assembly.

When it comes to assembly programming, the official instructions set reference manual is usually the main source of information for everything you write, so you should go to the ARM website and your exact CPU (6 pages long) as well as download 2 full documents. For example, both the iPhone 3G and iPhone 4 have the ARMV 7-A Cortex-A8 CPU, so that you can download (2000 pages long) which tells you which instructions are available and how they actually work. , And which describes the instruction time, etc. for your specific CPU.

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 ;!

sockets - Delphi: TTcpServer, connection reset when reading -

-
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
