एक urllib2 अनुरोध नीचे द्विआधारी प्रतिक्रिया प्राप्त करता है:

मैंने पहले 6 बाइट्स पर निम्न कोड वाले स्ट्रक्चर मॉड्यूल की कोशिश की:

लेकिन यह चाहिए आउटपुट (1, 4) मैं मैनुअल पर एक नज़र डालता हूं लेकिन मुझे पता नहीं था कि गलत क्या था।

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
