• Select calls seems to not time out.

  - by martsbradley

  HI Folks, I have a threaded C++ program where up to three threads are calling select on a three separate socket descriptors waiting for data to become available. Each thread handles one socket and adds it to the readfds with a timeout of 300 seconds. After select returns if there is data available I'm calling recv to read it. Is there anything that I need to be aware of with winsock and threads because for some reason after a number of hours the select calls all seem to be not timing out. Can a multi threaded program select from a number of threads without issue? I know that I should have one thread listening to all three sockets however that would be a large change for this app and I'm only looking to apply a bug fix. cheers, Martin.

• Problem running VBScript from my UIAccess VB app using MSScriptControl

  - by Ray

  I'm trying to run some VBSCRIPT from within my application. This works fine when I run my program from within VB. But once I add "UIAccess=true" to my manifest and digitally sign my exe with my certificate, I am unable to run the code any more. It gives errors when I try to interface with any program saying "429: ActiveX component can't create object: 'myApp.Application'". Anyone have any idea why it would run fine in the IDE but not with an application with uses UIAccess? Here is the code: Dim scriptRunner As New MSScriptControl.ScriptControlClass scriptRunner.Language = "VBScript" scriptRunner.AllowUI = True scriptRunner.Timeout = 3000 scriptRunner.AddCode(scriptStr) scriptRunner = Nothing

• Execute PHP after new Order in Magento

  - by Israel Lopez

  Hello There, I'm trying to figure out where I could drop in some PHP code to notify a CRM we are using (Solve360) that a new order has been placed, and that an event should be created (API) to fulfill the order. Order Product Checkout Complete Checkout & Capture CC Side notify CRM Done Not sure where to start, but I have had to make some small tweaks to fix the Quantum Gateway payment processor to work. In that module it appears that the objects for the order (email, amt, details) were available. However it seems it would be quite 'dirty' to insert more PHP code in there. Ideas? PHP 5.2.x & Magento 1.4.x

• app.config and 64-bit machines

  - by Dale Lutes

  I have an app that works fine on 32-bit systems, but fails on XP 64 bit systems. I've tracked it down to the connection string defined in my app.config thus: <connectionStrings> <clear/> <add name="IFDSConnectionString" connectionString="Data Source=fdsdata;Initial Catalog=IFDS; Trusted_Connection=true;Connect Timeout=0" providerName="System.Data.SqlClient" /> </connectionStrings> When I try to reference it in code, I find that the ConfigurationManager.ConnectionStrings collection only contains the LocalSqlServer connection string from the machine.config file and not my custom string. Another oddity is that it works fine when I run the app out of Visual Studio. It is only when I run out of the release folder that the connection string does not get defined. The application's .exe.config file is there in the release folder along with the .exe file and is up to date.

• Best solution to wait for all ajax callbacks to be executed

  - by glaz666

  Hi! Imagine we have to sources to be requested by ajax. I want to perform some actions when all callbacks are triggered. How this can be done besides this approach: (function($){ var sources = ['http://source1.com', 'http://source2.com'], guard = 0, someHandler = function() { if (guard != sources.length) { return; } //do some actions }; for (var idx in sources) { $.getJSON(sources[idx], function(){ guard++; someHandler(); }) } })(jQuery) What I don't like here is that in this case I can't handle response failing (eg. I can't set timeout for response to come) and overall approach (I suppose there should be a way to use more power of functional programming here) Any ideas? Regards!

• odd behavior setting timeouts inside a function with global references in javascript

  - by Pablo

  Here is the the function and the globals: $note_instance = Array(); $note_count = 0; function create(text){ count = $note_count++; time = 5000; $note_instance[count] = $notifications.notify("create", text); setTimeout(function(){ $note_instance[count].close() }, time); } The function simply opens a notification, a sets a timeout to close it in 5 seconds. so if i call this create("Good Note 1"); create("Good Note 2"); create("Good Note 3"); Ecah note should close 5 seconds from their creation, however always and only the last note closes, in this case "Good Note 3". Each note object has its own entry in the the $note_instance global array so the timeouts should no be overwriting themselves. What am i missing here folks? Thanks in advance

• Keep a javascript variable after an ajax call

  - by Guillaume le Floch

  I'm new in javascript and jQuery. I'm using ajax calls to get data from my server. The fact is, I'm losing my javascript variables after the call .. Here is what I did : the variable is define outside any function and treat in an other function. var a = 0; function myfunction(url){ $.ajax({ url: url, timeout: 20000, success: function(data){ // Do some stuff // The a variable is now undefined }, error: function(){ // Do some stuff } }); } Everything is working fine, the only thing is that I need to keep my variables ... but it looks like it's gone .. Does anyone know why? Thanks

• jQuery blockUI and AJAX POST

  - by oompahloompah

  I am using jQuery BlockUI in a project. For a particular user action, I want to block the UI, and then POST data to the server. When the timeout event occurs OR the server returns, I want to unblock the page. I can't seem to implement this behaviour. This is what I have so far (not working) $(document).ready(function(){ $('#test').click(function(event){ $.blockUI({ message: $('#syntax-chk') }); $.ajax({ type: 'POST', url: 'www.example.com', data: somedata, dataType: "json" }); setTimeout(function() { $.unblockUI({ onUnblock: function(){ alert('onUnblock'); } }); }, 2000); }); can anyone spot what I may be doing wrong?

• How much effort does it take to spoof an Ip Address in a call to a webservice?

  - by Rory Becker

  I don't want to know how... Just how complicated.... I'm thinking of securing a webservice or 2 based on the incoming client ipaddress of the caller. Is this in any way secure? Surely if the IPaddress was being spoofed then the result would have to be sent back to the address that was being spoofed and therefore not reach the spoofer? Update: Ok so from what I can tell.... I should create a Gettoken() method which checks the IPaddress and passes out a cryptographically significant token with a timeout to any valid IP address. This is then required by any other method before any kind of side effect is allowed. Since an Attacker can't (likely) get the token without having a valid IP, he will be unable to validly call any of my "dangerous" webmethods ?

• Warn user when new data is inserted on database

  - by João Menighin

  I don't know how to search about this so I'm kinda lost (the two topics I saw here were closed). I have a news website and I want to warn the user when a new data is inserted on the database. I want to do that like here on StackOverflow where we are warned without reloading the page or like in facebook where you are warned about new messages/notifications without reloading. Which is the best way to do that? Is it some kind of listener with a timeout that is constantly checking the database? It doesn't sounds efficient... Thanks in advance.

• Webservice for serial port devices

  - by camx

  Hi I want to create a remote webservice for an application that is now avaliable only localy. This application controlls three devices (each is controlled separately) connected on serial port. The problem is that I don't know how to take care of passing back information that a device return requested data. For example - I send move command to the motion device (which is very slow and can take a minute or more). Can I just set a big timeout on the client side (and server side) and return for example a true/false if operation is completed or is this a bad idea? Is SOAP with big timeouts ok? And the other question is if Mono on Linux (Ubuntu 9.10, Mono 2.4) is stable enought for making a web service or should I chose Java or some other language? I'm open for recommendations. Thanks for your help!

• Design guide-lines for writing a Typed SQL Statement API ?

  - by this. __curious_geek

  Last night I came up to sometihng intersting while designing my new project that brought me to ask this qustion here. My project is supposed to follow Table Gateway pattern using tradional ADO.Net datasets for data access. I don't want to write plain queries in my data-access classes. So I came up with an idea of writing a parser kindaa api that exposes objects and methods to generate queries on the move based on my domain objects. Later I want this api to hook up to my Business objects and provide Typed SQL generator api right on the business object instances. Any idea or references how can I do this ? This seems very wide to start with that I'm compelled take your opinions here. Does there anything already exists that can do this ?

• jQuery.Form wont submit

  - by kim

  Im´trying to submit a form without refreshing the page, but I´m having a problem. When I click submit the page refreshes and anothing gets posted. Here is the code, what am I doing wrong? (I´m a newbie) jQuery 1.4.2 and the jQuery Form Plugin 2.43 is present. tnx $(document).ready(function() { var options = { target: '#output2', url: https://graph.facebook.com/<%=fbUid%>/feed, type: post, clearForm: true // clear all form fields after successful submit //dataType: null // 'xml', 'script', or 'json' (expected server response type) //resetForm: true // reset the form after successful submit // $.ajax options can be used here too, for example: //timeout: 3000 }; // bind to the form's submit event $('#fbPostStatus').submit(function() { // inside event callbacks 'this' is the DOM element so we first // wrap it in a jQuery object and then invoke ajaxSubmit $(this).ajaxSubmit(options); // !!! Important !!! // always return false to prevent standard browser submit and page navigation return false; }); });

• Using MySQL as a job queue

  - by user237815

  I'd like to use MySQL as a job queue. Multiple machines will be producing and consuming jobs. Jobs need to be scheduled; some may run every hour, some every day, etc. It seems fairly straightforward: for each job, have a "nextFireTime" column, and have worker machines search for the job with the nextFireTime, change the status of the record to "inProcess", and then update the nextFireTime when the job ends. The problem comes in when a worker dies silently. It won't be able to update the nextFireTime or set the status back to "idle". Unfortunately, jobs can be long-running, so a reaper thread that looks for jobs that have been inProcess too long isn't an option. There's no timeout value that would work. Can anyone suggest a design pattern that would properly handle unreliable worker machines?

• Squid+iptables: how do i allow https to pass-through and bypassing Squid?

  - by logansama

  Hello, Basically started with Squid and iptables today (google is your friend). This stuff is going to be the death of me. I have Squid3 setup on Ubuntu 9.04 server as Transparent Proxy. It works sweetly when i use the proxy-box as my default gateway etc. The iptable rules for this setup was part of the tutorial. :P I can unfortunately not access https sites (such as Gmail or anything on port 443 basically). This is because Squid dont like what it cannot cache, which in this case is the https traffic. I would like to add an iptable rule so that i can basically access https sites and use Skype. Basically allow these types of traffic to pass through without going through Squid proxy? (bypassing it so to speak) Would anyone perhaps know how to do this or have a link to any sources that would assist me in figuring it out? Thank you.

• C/C++ detect network type

  - by Gavimoss

  I need to write a win32 c/c++ application which will be able to determine whether the PC it's running on is connected to one of 2 networks. The first network is the company LAN (which has no internet connection) and the second network is a standalone switch with a single PC connected to it (the PC that the program is running on). I'm pretty new to network programming but so far I have tried testing to see if a network drive which is held on our LAN can be mapped. This works fine if the PC is connected to the LAN, the drive mapping succeeds so so LAN detection is successful. However, if the PC is connected to the switch, this results in a VERY long timeout which is not a suitable as it will delay the program so much as to make it unusable. Does anyone have any alternative suggestions? I'm using c/c++ in VS 6.0

• Need help with writing from XML to a SQL Server database (detailed)

  - by fogedi

  I'm a bit of a newbie with XML and WebServices and stuff like that. I'm working on a project using GlassFish OpenESB to schedule a process to get some information from a webservice and then store in a database. The criteria is basically that i have to use GlassFish OpenESB or EJB modules where i can expose webservices or something along those lines, AND i have to use SQL Server 2005. So far I've been able to talk to the webservice: and receive something along those lines <?xml version="1.0" encoding="UTF-8" standalone="no"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://schemas.xmlsoap.org/soap/envelope/ http://schemas.xmlsoap.org/soap/envelope/"> <SOAP-ENV:Body> <m:entrypoint_getSettlementsOperationResponse xmlns:m="http://j2ee.netbeans.org/wsdl/BorgunTestBPEL/entrypoint_getSettlements"> <part1> <GetSettlementsByMerchantResponse xmlns="http://Borgun.Services.Gateway/2010/04/Settlement"> <GetSettlementsByMerchantResult xmlns:a="http://schemas.datacontract.org/2004/07/Borgun.Library.Common" xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns:msgns="http://Borgun.Services.Gateway/2010/04/Settlement" xmlns:ns0="http://j2ee.netbeans.org/wsdl/BorgunTestBPEL/entrypoint_getSettlements"> <a:CreditCardSettlement> <a:amexAmount>XXX</a:amexAmount> <a:amount>XXXX</a:amount> <a:batches> <a:CreditCardBatch> <a:batchdate>xxx</a:batchdate> <a:batchnumber>XXXX</a:batchnumber> <a:currencyCode>xxxx</a:currencyCode> <a:merchantnumber>xxxx</a:merchantnumber> <a:settlementRunNumber>xx4</a:settlementRunNumber> <a:settlementdate>2010-04-06T00:00:00</a:settlementdate> <a:slips>2</a:slips> <a:sum>xxxx</a:sum> </a:CreditCardBatch> <a:CreditCardBatch> <a:batchdate>xxx</a:batchdate> <a:batchnumber>xxxxx</a:batchnumber> <a:currencyCode>xxxx</a:currencyCode> <a:merchantnumber>xxxx</a:merchantnumber> <a:settlementRunNumber>xxxx</a:settlementRunNumber> <a:settlementdate>xxxx</a:settlementdate> <a:slips>x</a:slips> <a:sum>xxx</a:sum> </a:CreditCardBatch> </a:batches> <a:commission>xx</a:commission> <a:currencyCode>xxx</a:currencyCode> <a:deduction>-xxx</a:deduction> <a:deductionItems> <a:CrediCardSettlementDeduction> <a:amount>-xxx</a:amount> <a:code>VIÐSKF</a:code> <a:currencyCode>ISK</a:currencyCode> <a:merchantnumber>xxx</a:merchantnumber> <a:settlementrunnumber>xxx</a:settlementrunnumber> <a:text>Afsláttur v/ekorta</a:text> </a:CrediCardSettlementDeduction> <a:CrediCardSettlementDeduction> <a:amount>-335.00</a:amount> <a:code>ÁLAGKREK</a:code> <a:currencyCode>ISK</a:currencyCode> <a:merchantnumber>xxx</a:merchantnumber> <a:settlementrunnumber>xxx</a:settlementrunnumber> <a:text>xxx</a:text> </a:CrediCardSettlementDeduction> </a:deductionItems> </a:CreditCardSettlement> </GetSettlementsByMerchantResult> </GetSettlementsByMerchantResponse> </part1> </m:entrypoint_getSettlementsOperationResponse> </SOAP-ENV:Body> </SOAP-ENV:Envelope> I have access to the SQL Server 2005 server which is remote and i know i can insert into it but given that now i have a one-to-many relationship i want to be able to rollback if something fails. So in short how can I insert from this XML into the DB preferably without manually walking through the XML tree? I'm pretty sure I'm supposed to be able to use Entity and Session Beans or maybe JAXB bindings but I'm simply not being successful. One of the reasons might have something to do with the fact that the soap response contains an array of CreditCardSettlements and each of which contains an array of Batches and DeductionItems It would be best if someone can help me do this via a BPEL in GlassFish OpenESB but any hint at a java solution is much appreciated.

• Disable Bluetooth discoverable mode on Android

  - by Venator85

  Hi, I found in the Android documentation how to turn Bluetooth discoverability mode on: Intent discoverableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE); discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 300); startActivity(discoverableIntent); This will make the device discoverable for 300 seconds (documentation). My question is: how to turn discoverability OFF before this timeout occurs? I'd like to replicate the corresponding setting in Settings|Wireless and networks|Bluetooth settings applet, that allows discoverability to be turned on and off with a click. Any help? Thanks ;)

Can someone help me solve this problem. Note: The url I am trying to read contains a json response so everything is in one line I think thats why I am having some content missing.

• How to terminate a managed thread blocked in unmanaged code?

  - by James Curran

  I have a managed thread which is waiting, blocked, in an unmanaged code (specifically, it on a call to NamedPipeServerStream.WaitForConnection() which ultimitely calls into unmanaged code, and does not offer a timeout). I want to shut the thread down neatly. Thread.Abort() has no effect until the code returns to the managed realm, which it won't do until a client makes a connection, which we can't wait for). I need a way "shock" it out of the unmanaged code; or a way to just kill the thread even while it's in unmanaged land.
