  • Help to run it in the background

    - by AlexPolo
    Here's a simple python daemon I can't manage to run as a background process: #!/usr/bin/env python import socket host = '' port = 843 backlog = 5 size = 1024 s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.bind((host,port)) s.listen(backlog) while 1: client, address = s.accept() data = client.recv(size) if data == '<policy-file-request/>\0': client.send('<?xml version="1.0"?><cross-domain-policy><allow-access-from domain="*" to-ports="*"/></cross-domain-policy>') client.close() It's a socket policy file server (you may have heard of the restiction Adope put on socket connection - http://www.adobe.com/devnet/flashplayer/articles/socket_policy_files.html); that works well when gets run like an "ordinary" process - "python that_server.py", - but I get problem to run it in the background. Running like so: "that_server.py &", - does not work.

  • creating ports and initiating communication between client and server

    - by dave
    what i need is a server that listens to 5060 port , when the client sends data to that port the server should open up another port ( any port after 1250 i believe ) and forward the clients data to that port keeping 5060 idle so it can perform the same function for the next client so basically i need the server to a) open up multiple ports one for each client b) get the voice data from the client and be able to send voice data to that client i m looking into the hardware specs and other such details of the scenario so i dont have time to make such a program myself if theres a code that i can run directly ( both server and client side ) on visual studio .net 2010 that will perform these tasks then that would be extremely helpful thanks alot in advance

  • URIs vs Hidden Forms

    - by NateDogg
    I'm working in the Codeigniter framework, and want to send requests to my controller/model that have several variables involved. Is there a difference between passing those variables via a hidden form (i.e. using "post") as opposed to passing them through URIs (e.g. 'travel/$month/$day/')? What about security concerns? e.g. URIs: http://www.example.com/travel/$month/$day/ Hidden Form: form_hidden('month',$month); form_hidden('day',$day);

  • Mac OS X Services: enable without user interaction?

    - by kclement
    I wrote a simple Mac 'Service' for Finder, that executes a command. Basically: this adds a ContextMenu in Finder. If I right-click a file in Finder, a menu item pops up. If the user clicks it, it executes my script. (kind of like 'Send to Bluetooth device, ...') In OS X Leopard (10.5) and earlier, all services are enabled. In 10.6 (Snow Leopard), Apple changed the behavior, services now have preferences, and can be enabled or disabled by the user. (which is a good thing) However, I wrote the service, but there seems to be no way to enable it automatically (in our installer). I tried doing it with Applescript, going to the System Preferences and ticking the checkbox that way, but it requires some accessibility features to be turned on. (off by default). Is it possible? If so, how? Or do I need something else to provide Context Menus in Finder.

  • how to copy char * into a string and vice-versa

    - by user295030
    If i pass a char * into a function. I want to then take that char * convert it to a std::string and once I get my result convert it back to char * from a std::string to show the result. I don't know how to do this for conversion ( I am not talking const char * but just char *) I am not sure how to manipulate the value of the pointer I send in. so steps i need to do take in a char * convert it into a string. take the result of that string and put it back in the form of a char * return the result such that the value should be available outside the function and not get destroyed. If possible can i see how it could be done via reference vs a pointer (whose address I pass in by value however I can still modify the value that pointer is pointing to. so even though the copy of the pointer address in the function gets destroyed i still see the changed value outside. thanks!

  • How do I handle user authorization the safest way?

    - by Irro
    I'm developing a small website where I'm going to allow user to create accounts but I'm quite clueless when it comes to safety around authorizations. I have built my project in PHP with codeigniter and found a library (Tank Auth) that could handle authorization for me. It stores password in a safe way but I'm still worried about the part when the user sends their password to my server. One easy way to do it would be to send the password in a post-request but I would guess that it's quite easy to sniff such a password. Should I do something with the password on the client side before sending it to my server? And is there any good javascript libraries for this?

  • How to assign a PHP variable that contains a mixed of PHP and html elements?

    - by Rick
    I have a PHP page that contains html and tags and PHP codes and I am using AJAX to manipulate some data and now I need to spit out the response but I am not sure if it is possible to put the mixed content into a string variable to pass through... Is this possible? For example I need to: $response = "<p>some text--<?php echo $something; ?>"; Thanks... To clear things up, I am not trying to send raw PHP code to clientside as that would be silly and won't be evaluated as it is a server side script. I am just looking for a fast way to put everything into a variable without manually re-doing the whole page stripping out the php open and close tags and echos...etc

  • Share Link - Perform action in background

    - by Justin
    I have an application that will accept URLs from the built in web browser via the "Share page" menu item. I'm using the send intent and it works just fine. However, I'd like to accept a URL and process it in the background without bringing my application to the front. I don't want the user to have to actually leave the web browser. It will notify the user it has finished processing the URL with a Toast message. I'm just not sure what type of activity should be used for this. A good example of this behavior is the "Read Later" instapaper application in the android market. Any help would be greatly appreciated.

  • receive xml file via post in php

    - by thegunner
    Hi, I'm looking for a PHP script that can accept an XML file via a POST, then send a response.... Does anyone have any code that could do this? So far the only code I have is this but not sure about the response or if indeed I am even going in the right direction as XML characters are not saved correctly. Any ideas? <?php if ( $_SERVER['REQUEST_METHOD'] === 'POST' ){ $postText = file_get_contents('php://input'); } $datetime=date('ymdHis'); $xmlfile = "myfile" . $datetime . ".xml"; $FileHandle = fopen($xmlfile, 'w') or die("can't open file"); fwrite($FileHandle, $postText); fclose($FileHandle); ?> Thanks,

  • Google checkout - Order processing notification handler

    - by Kunal
    Hi I need to integrate google checkout on my website. I have successfully implemented the order placing and others stuff and using the sandbox I have tested that users can successfully add items to cart and and pay thereafter. I am using my own customized shopping cart written in php mysql. The last thing I need to do is pass the new order id to google checkout and receive notifications with the new order id as well as other data google sends. I know I have to setup a path to the handler script in my accounts. I did it in my sandbox account as well. But can't find a simple pice of code to get it done. Even if I use sample code from google, just cant figure out the format of the returned data in new order notification and also how to send custom data to the cart, which would come back with new order notifications? I am just lost on this. Please help!

  • How to create a fully qualified hyperlink to a resource dynamically?

    - by Slauma
    In ASP.NET I'd like to create a link which points to a specific Uri and send this link in an email to a user, for instance something like http://www.BlaBla.com/CustomerPortal/Order/9876. I can create the second part of the Uri /CustomerPortal/Order/9876 dynamically in code-behind. My question is: How can I create the base Uri http://www.BlaBla.com without hardcoding it in my application? Basically I want to have something like: http://localhost:1234/CustomerPortal/Order/9876 (on my development machine) http://testserver/CustomerPortal/Order/9876 (on an internal test server) http://www.BlaBla.com/CustomerPortal/Order/9876 (on the production server) So is there a way to ask the server where the application is running: "Please tell me the base Uri of the application" ? Or any other way? Thank you in advance!

  • Need a push in the right direction, to write my first functional test in Rails

    - by Jason
    I've read quiet a bit of documentation over the last few days about testing in Rails, I'm sitting down to write my first real test and not 100% sure how to tie what I have learned together to achieve the following functional test (testing a controller) I need to send a GET request to a URL and pass 3 parameters (simple web-service), if the functionality works the keyword true is simply returned, otherwise the keyword false is returned - its in only value returned & not contained in any <div>, <span> or other tags. The test should assert that if "true" is returned the test is successful. This is probably very simple so apologies for such a non-challenging question. If anyone could point me in the write direction on how I can get started, particularly how I can test the response, I'd be very grateful!

  • iPhone App : Storing / Saving personal preferences once per App

    - by sg
    Hi, I want to store / save personal preference settings like Email, Phone number for an App. I have few forms which send info by Email to my ID. I want to know the Email & Phone number of user so I can contact this person if need be. I don't want users to keep entering their Email ID & Phone No. everytime in each form. It's wise to take these inputs (Email & Phone) just once per device / per App installed on the device. I am trying to use .plist for this purpose. I have no success. How do I do it? Any example code (or) links? Thanks. I would appreciate any help.

  • .net, C# Interface between Business Logic and DAL

    - by Joel
    I'm working on a small application from scratch and using it to try to teach myself architecture and design concepts. It's a .NET 3.5, WPF application, and I'm using Sql Compact Edition as my data store. I'm working on the business logic layer, and have just now begun to write the DAL. I'm just using SqlCeComamnds to send over simple queries and SqlCeResultSet to get at the results. I'm starting to design my Insert and Update methods, and here's the issue - I don't know the best way to get the necessary data from the BLL into the DAL. Do I pass in a generic collection? Do I have a massive parameter list with all the data for the database? Do I simply pass in the actual business object (thus tying my DAL to the conrete stuff in the BLL?). I thought about using interfaces - simply passing IBusinessObjectA into the DAL, which provides the simplicity I'm looking for without tying me TOO tightly to current implementations. What do you guys think?

  • Does writing program using global variables is safer?

    - by ZoZo123
    I was reading about buffer, stack and heap overflows. I read this post as well. my question is like that: if I use only global variables in my code, can I say it prevents all the exploits of overflow? let's say I have this buffers in code declared in the global scope: char buf1[10]; char buf2[100]; If I send buf1 as the buffer to recv(int s, char *buf, int len,int flags); I will overwrite the data segment and may ruin the buf2 content, right? Would I be able to run a code from it because as I know it is not a code segment and data segment is not executable. Can we conclude that using Globals is the safest way?

  • Website image caching with Apache

    - by Piskvor
    How can I get static content on Apache to be {cached by browser} and not {checked for freshness {with every request}}? I'm working on a website hosted on Apache webserver. Recently, I was testing something with headers (Content-Type for different types of content) and saw a lot of conditional requests for images. Example: 200 /index.php?page=1234&action=list 304 /favicon.ico 304 /img/logo.png 304 /img/arrow.png (etc.) Although the image files are static content and are cached by the browser, every time an user opens a page that links to them, they are conditionally requested, to which they send "304 Not Modified". That's good (less data transferred), but it means 20+ more requests with every page load (longer page load due to all those round-trips, even with Keep-Alive and pipelining enabled). How do I tell the browser to keep the existing file and not check for newer version? EDIT: the mod_expires method works, even with the favicon.

  • Split text files Accross threads

    - by Kevin
    The problem: I have a few text files (10) with numbers in them on every line. I need to have them split across some threads I create using the pthread library. these threads that are created (worker threads) are to find the largest prime number that gets sent to them (and over all the largest prime from all of the text files). My current thoughts on solutions: I am thinking myself to have two arrays and all of the text files in one array and the other array will contain a binary file that I can read say 1000 lines and send the pointer to the index of that binary file in a struct that contains the id, file pointer, and file position and let it crank through that. a little bit of what I am talking about pthread_create(&threads[index],NULL,calc_sqrt,(void *)threadFields[index]);//Pass struct to each worker Struct: typedef struct threadFields{ int *id, *position; FILE *Fin; }tField; If anyone has any insight or a better solution it would be greatly appreciated Thanks
