  • Web serivce time out errors in delphi

    - by JD
    Hi, I have a client application that makes SOAP requests. I have set the timeout to 20 minutes. However, sometimes I see the timeout error occurring after 10 seconds. I have the following in code: RIO.HTTPWebNode.ReceiveTimeout := 1200000 Do I need to set the ConnectTimeout and SendTimeOut? Currently they are set to the default values of 0. What difference would setting these make? I am using Delphi 2007. Looking further at the error message I see I get "The operation timed out....". So should I be setting my ReceiveTimeOut to zero since I really do not want any timeout at all?

  • Python equivalent of IDL's stop and .reset

    - by Jamie
    Hi there, I'm relatively new to python but have a bit of experience using IDL. I was wondering if anyone knows if there are equivalent commands in python for IDL's stop and .reset commands. If I'm running some IDL script I wrote that I put a stop command in, essentially what it does is stop the script there and give me access to the command line in the middle of the script. So I have access to all the functions and variables that I defined before the stop command, which I find really useful for debugging. The .reset command I find extremely useful too. What it does is reset the the IDL environment (clears all variables, functions, etc.). It's as if I closed that session and opened a new one, but without having to exit and restart IDL. I find that if I'm trying to debug a script I wrote it's useful sometimes to start from scratch and not have to reset IDL (or python now). It would be useful also in python to be able to un-import any modules I had previously imported. Any help with these issues would be greatly appreciated. Cheers Related Python Drop into REPL Is it possible to go into ipython from code?

  • Where did the "Polymorphism" word come from?

    - by Alon
    I've always wondered where did the word "Polymorphism" word come from. I know what is polymorphism and I use it of course, but I just don't understand why this technique called polymorphism. Note that I'm not a native English speaker, and I will thank you if you'll use simple English in your answers. Thank you.

  • Generic Data Structure Description Language

    - by Jon Purdy
    I am wondering whether there exists any declarative language for arbitrarily describing the format and semantics of a data structure, that can be compiled to a specific implementation of that structure in any of a set of target languages. That is, something like a generic data definition language but geared toward describing arbitrary data structures such as vectors, lists, trees, etc., and the semantics of operations on those structures. I ask because I had an idea for a feasible implementation of this concept, and I'm just wondering whether it's worth it, and, consequently, whether it's been done before. Another, slightly more abstract question: is there any real difference between the normative specification of a data structure (what it does) and its implementation (how it does it)?

In other words, I want rid of columns 3,4,5. I have tried using cut to keep the columns that I do want and having " " as my delimiter however because of the file size figures, it messes up using "space" as a delimiter. Any advice would be much appreciated! Oh just to add, I would like to save the output as another text file. Many thanks!

  • What's the simplest way to call Http GET url using Delphi?

    - by Mohammed Nasman
    There's a web services I want to call in my application, I can use it with importing the WSDL or by just use "HTTP GET" with the URL and parameters, so I prefer the later because it's simple thing. I know I can use indy idhttp.get, to do the job, but this is very simple thing and I don't want to add complex indy code to my application. UPDATE: sorry if I was not clear, I meant by "not to add complex indy code", that I don't want add indy components for just this simple task, and prefer more lighter way for that.

  • ansi-c fscanf problem

    - by mongoose
    hi i read the file as follows fscanf(fp,"%f %f %f",&*(p1+i), &*(p2+i), &*(p3+i)); my file's lines consists of three floating point numbers... the problem i have is that in the file let's say i have some floating points with let's say maximum of two digits after the dot. but when i ask c to print those values using different formatting, for example %lf,%.2lf,%.4lf... it starts to play with the digits... my only concern is this, if i have let's say 1343.23 in the file, then will c use this value exactly as it is in computations or it will play with the digits after the dot. if it will play, then how is it possible to make it so that it uses floating point numbers exactly as they are? for example in last case even if i ask it to print that value using %.10lf i would expect it to print only 1343.2300000000.? thanks a lot!

  • When is calculating or variable-reading faster?

    - by Andreas Hornig
    hi, to be honest, I don't really know what the "small green men" in my cpu and compiler do, so I sometimes would like to know :). Currently I would like to know what's faster, so that I can design my code in a more efficient way. So for example I want to calclate something at different points in my sourcecode, when will it be faster to calculate it once and store it in a variable that's read and used for the next points it's needed and when is it faster to calculate it everytime? I think it's depending on how "complex" and "long" the calculation is and how fast then cache is, where variables are stored, but I don't have any clue what's faster :). Thanks for any reply to my tiny but important question! Andreas PS: perhaps it's important to know that I code in JAVA, but it's more a genral question.

  • iPhone to iPhone communication

    - by Dan
    Hi, I have been looking into communication methods between two iPhone devices and as I understand it there are two main methods to do this: Bluetooth and WiFi. However I wanted to know if anyone knows of any other way of sharing information between two iPhones? If I were in an area with no WiFi or mobile signal, and couldn't use Bluetooth for whatever reason, is there anything that could be done to broadcast data from one iPhone to another? I'm sure its a bit of a silly question, but if you don't ask, you don't get; and if someone knows of anything I might be able to look into with regards to this, I would be very appreciative. Thanks, Dan

  • Bash Shell; read command; using Cygwin on Windows 7

    - by user312397
    Okay so I am having this problem. I write up a script to be run in cygwin on Windows. I've tried a bunch of basic example scripts in case it was my scripts problem. So I tried this: #!/bin/bash echo -e "Enter your name and press [ENTER]: \c" read var_name echo "Your name is: $var_name" Then I will run it and I enter a name for var_name. I get this: $ ./project1.sh Enter your name and press [ENTER]: Jake ': not a valid identifierad: `var_name Your name is: So as far as I understand it I am having a problem with read. I am trying to work on a project for my class, but I can't seem to figure out why it won't read it. I followed the book with no triumph then resorted to these examples on the web that do not seem to work for me either. Does anyone have any idea if it is my setup or if I am missing something, thanks.

  • Any PICK programmers on stack?

    - by Coov
    I work in a shop that is divided into two types of programmers. Programmers that code in .net & sql and programmers that code in pick. Actually, a few of the programmers are writing code in both pick and .net. I was curious if there are any pick programmers out there using StackOverflow? I'd like to get the pick programmers involved in the stack community.

  • Multithreading or task parallel library

    - by Bruce Adams
    I have an application which performs 30 independent tasks simultaneously using multithreading, each task retrieves data over http, performs a calculation and returns a result to the ui thread. Can I use tpl to perform the same tasks? Does tpl create 30 new threads and spread them over all the available cores, or does it just split the tasks over the available cores and use one thread per core? Will there be a performance boost using tpl over multithreading in this case?

  • New to Linux Kernel/Driver development...

    - by CVS-2600Hertz-wordpress-com
    Recently, i began developing a driver of an embedded device running linux. Until now i have only read about linux internals. Having no prior experience in driver devlopment, i am finding it a tad difficult to land my first step. I have downloaded the kernel source-code (v2.6.32). I have read (skimped) Linux Device Drivers (3e) I read a few related posts here on StackOverflow. I understand that linux has a "monolithic" approach. I have built kernel (included existing driver in menuconfig etc.) I know the basics of kconfig and makefile files so that should not be a problem. Can someone describe the structure (i.e. the inter-links) of the various folders in the kernel-source code. In other words given a source-code file, which other files would it refer to for related code (The "#include"-s provide a partial idea) Could someone please help me in getting a better idea? Any help will be greatly appreciated Thank You.

  • How to reuse socket in .NET?

    - by Hermann
    I am trying to reconnect to a socket that I have disconnected from but it won't allow it for some reason even though I called the Disconnect method with the argument "reuseSocket" set to true. _socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); _socket.Connect(ipAddress, port); //...receive data _socket.Disconnect(true); //reuseSocket = true //...wait _socket.Connect(ipAddress, port); //throws an InvalidOperationException: Once the socket has been disconnected, you can only reconnect again asynchronously, and only to a different EndPoint. BeginConnect must be called on a thread that won't exit until the operation has been completed. What am I doing wrong?

  • Alternatives to Java for Android development?

    - by paul.meier
    Hey all, I've started developing Android apps a couple of months ago, and have a few under my belt. While I can tolerate Java enough to keep developing, I was wondering what success the community has had getting other languages to run. I've done some investigation as to how other JVM languages work, and it appears Dalvik messes them up pretty hard. Clojure seems unable to run, Scala seems to be one of the most successful. JRuby has also had some luck, but they caution against anything major. I've also checked out Scheme via Moby and Kawa, both of which seem to have some promise. What luck have any of you had? Languages I'm missing, misrepresenting? Any non-"Hello World" apps you've written in non-Java? Any snags in trying to get another language to run (e.g. "as long as you don't use continuations, you're fine in X Scheme"). Any particular snags in developing apps non-Java, once you get them to run? Thanks, hope you well ^_^
