  • how to print a char od struct()

    - by make
    Hi Could someone please tell us to print a char when receiving data as a truct? here is an EXP: ... struct rcv{ int x1; float x2; char x3; }; rcv data_rcv; ... if (recv(socket, &data_rcv, sizeof(data_rcv), 0) < 0) printf("recv() failed"); ... printf("x1 = %d\n", data_rcv.x1); printf("x2 = %f\n", data_rcv.x2); printf("x3 = %s\n", data_rcv.x3); // it doesn't print anything, why? ...

  • looking for advise on importing excel into mysql with php

    - by Ole Media
    Alright, see if I can pick your brains from you all. I'm currently working on a project where all the information comes from different clients, the only thing in common is that the received data is done with excel. The excel spread sheet that they present is just a bunch of references and codes, and the problem than I'm facing is that I need the references and codes to be entered in certain format in order for the website to work. The perfect situation will be to go to each client and teach how I would need the data, but I can't do that because of the large number of clients, and more importantly I will be interrupting their work flow. Each client has its own codes and reference model and they are not willing to change their process The good news is that there is a standard pattern for the codes, but I'm talking close to 200 thousand codes with a bunch of combination. They way that we are currently solving the problem is that we have a person who checks each excel sheet received, runs a few macros, and manually fixes those codes in which the macro was not able to fix. The person that is doing this, is already burn out and frustrated and I would like to automatize this process with php. Suggestions?

  • Backup of "Leavers" network directory

    - by Mez
    I want to create a backup of a Leavers network home directory. I've generally done this before by just creating an iso with genisoimage and then burning it. However, it seems that the latest users have 10G in their files. For archival purposes, I want to be able to burn these to multiple DVDs. How do I create these DVD iso images (I know it's got something to do with tar and stream-media-size, and then how do I restore them if I need them again? Using Debian

  • Access MacZFS via network from XBMC

    - by AreusAstarte
    I have a ZFS RAID (zpool with three drives) hooked up to my Mac that I want to share in my LAN so that the XBMC client on my OUYA console hooked up to the television can read the drive and use it to stream my movies and television shows onto the television set. I've searched around for a bit but so far haven't found anything that helped me with it. I know that when connecting to the Mac with SSH I can't just access the drive due to different formatting. What do I have to do so that XBMC will be able to read it? How do I share it?

  • Prompting for authentication from a wxPython program and passing it along to IIS?

    - by MetaHyperBolic
    I have a client (written in Python, with a wxPython front end in dead-simple wizard style) which communicates a website running IIS. A python script receives requests and does the usual client-server dance. I would have written this as a browser application, but for the requirement that certain things happen on the local PC that the web can't help with (file manipulation, interfacing with certain USB hardware, etc.) Right now, I am simply using the logon credentials, compounded as a string from os.environ['USERDOMAIN'] and os.environ['USERNAME'], to pass along to the server, which connects to Active Directory and enumerates the members of the group, looking for those logon credentials. It's an ugly hack, but it works. Obviously, I could make people log out of the generic helper accounts and log back into Windows using specific accounts. However, I wondered how feasible it would be to provide some kind of logon prompt wherein the user can type in a name and password, then some kind of authorization token could be passed on to IIS. This seems like something I would not want to do myself, given that amateurs almost always make huge security mistakes. Now you can see why I am wishing this was purely web-based. What's a good way to handle this?

  • sendto is returning ENOBUF

    - by user338159
    Hi, I am currently running an old system on Tru64 which involves lots of UDP sockets using the sendto() function. The sockets are used in our code to send messages to/from various processes and then eventually on to a thick client app that is connected remotely. Occasionally the socket to the thick client gets stuck, this can cause some of these messages to get built up. My question is how can I determine the current buffer size, and how do I determine the maximum message buffer. The code below gives a snippet of how I set up the port and use the sendto function. /* need to adjust the maximum size we can send on this / / as it needs to be able to cope with the biggest / / messages we send / lenlen = sizeof(len) ; / allow double for when the system is under load */ len = 2 * C_MAX_MESSAGE_DATA_SIZE ; lpos_setsockopt(FATAL, msg_socket,SOL_SOCKET, SO_SNDBUF, &len, lenlen, &error_no) ; result = sendto( msg_socket, (char *)message, (int)message_len, flags, dest_addr, addrlen); Note. We have ported this application to Linux and the problem does not seem to appear there. Any help would be greatly appreciated. Regards

  • When to define SDD operations System->Actor?

    - by devoured elysium
    I am having some trouble understanding how to make SDDs, as I don't fully grasp why in some cases one should define operations for System - Actor and in others don't. Here is an example: 1) The User tells the System that wants to buy some tickets, stating his client number. 2) The System confirms that the given client number is valid. 3) The User tells the System the movie that wants to see. 4) The System shows the set of available sessions and seats for that movie. 5) The System asks the user which session/seat he wants. 6) The user tells the System the chosen session/seat. This would be converted to: a) -----> tellClientNumber(clientNumber) b) <----- validClientNumber c) -----> tellMovieToSee(movie) d) <----- showsAvailableSeatsHours e) -----> tellSystemChosenSessionSeat(session, seat) I know that when we are dealing with SDD's we are still far away from coding. But I can't help trying to imagine how it how it would have been had I to convert it right away to code: I can understand 1) and 2). It's like if it was a C#/Java method with the following signature: boolean tellClientNumber(clientNumber) so I put both on the SDD. Then, we have the pair 3) 4). I can imagine that as something as: SomeDataStructureThatHoldsAvailableSessionsSeats tellSystemMovieToSee(movie) Now, the problem: From what I've come to understand, my lecturer says that we shouldn't make an operation on the SDD for 5) as we should only show operations from the Actor to the System and when the System is either presenting us data (as in c)) or validating sent data (such as in b)). I find this odd, as if I try to imagine this like a DOS app where you have to put your input sequencially, it makes sense to make an arrow even for 5). Why is this wrong? How should I try to visualize this? Thanks

  • About Web service ,how to use Ajax to call a specific member function of a class?

    - by Liu chwen
    I'm trying to build a web service by PHP. In my case, I called the getINFO(), but the return value on client side always null. Have no idea to solve this problem.. Here's the SOAPserver code(WS.WEB_s.php): require("WEB_s.php"); ini_set("soap.wsdl_cache_enabled", 0); $server = new SoapServer('wsdl/WEB_s.wsdl'); $server->setClass("WEB_s"); $server->handle(); Where the main Class is(WEB_s.php): final class WEB_s { public function getINFO(){ $JsonOutput = '{"key":"value",...}'; return $JsonOutput; } public function setWAN($setCommand,$newConfigfilePath){ $bOutput; return $bOutput; } } And Client side: $(document).ready(function(){ $('#qqq').button().click(function(){ var soapMessage = LoginSoap($('#uid').val(),$('#pwd').val()); alert('soapMessage'); $.ajax({ //url: 'libraries/WS.WEB_s.php/WEB_s/getINFO',//success , return null //url: 'libraries/WS.WEB_s.php/', //success , return null url: 'libraries/WS.WEB_s.php/getINFO',//success , return null type: 'GET', timeout: (10* 1000), contentType: "text/xml", dataType: "xml", success: function( data,textStatus,jqXHR){ alert('Server success(' + data+')('+ textStatus + ')(' + jqXHR + ')'); }, error: function (request, status, error) { alert('Server Error(' + status+')->'+error); }, complete: function (jqXHR, textStatus) { alert('Server success(' + jqXHR+')('+ textStatus + ')'); } }); }); }); The following is the corresponding WSDL file : http://codepaste.net/95wq9b

  • Ruby 1.9: turn these 4 arrays into hash of key/value pairs

    - by randombits
    I have four arrays that are coming in from the client. Let's say that there is an array of names, birth dates, favorite color and location. The idea is I want a hash later where each name will have a hash with respective attributes: Example date coming from the client: [name0, name1, name2, name3] [loc0, loc1] [favcololor0, favcolor1] [bd0, bd1, bd2, bd3, bd4, bd5] Output I'd like to achieve: name0 => { location => loc0, favcolor => favcolor0, bd => bd0 } name1 => { location => loc1, favcolor => favcolor1, bd => bd1 } name2 => { location => nil, favcolor => nil, bd => bd2 } name3 => { location => nil, favcolor => nil, bd => bd3 } I want to have an array at the end of the day where I can iterate and work on each particular person hash. There need not be an equivalent number of values in each array. Meaning, names are required.. and I might receive 5 of them, but I only might receive 3 birth dates, 2 favorite colors and 1 location. Every missing value will result in a nil. How does one make that kind of data structure with Ruby 1.9?

  • Switch front-end's of a website after X amount of hits

    - by Derek Adair
    Sorry about the title - not sure what to call this one. A client of mine would like to redirect users to different front-ends of his eCommerce site based on a hit-counter (possibly a timer?). important: -The content is moderately different in the two sites, enough to consider them two different websites. Knowing this client he will likely add more drastic content changes and other front-ends. So for this question consider the content to be -This site has a rather large back-end. With affiliate networking, multiple payment gateways, order-tracking, and several other features in the works. It is essential that these two front-ends have identical back-end functionality I know that if it was just a simple CSS swap this would be as simple as an if statement that ran off some kind of counter stored in a DB... but the different HTML markup is throwing me for a loop. Q: How can I serve two different front-ends (HTML/CSS) based on a hit counter? Also, I don't have any clue what to tag this one as...

  • How can I organize my video collection and update meta data?

    - by Pieter Breed
    I have a large collection of downloaded video files containing different movies, tv shows and music videos. I have a FreeNAS box set up that uses Fuppes as a UPnP media server. My media player on Windows correctly detects this UPnP collection and can stream from it fine. However, All of my music videos, tv shows and movies are all sorted under the same 'Videos' group. I would like to seperate the different types of video files so that they can correctly go under 'Recorded TV' or whatever the case may be. Any ideas? I guess I am looking for something like an MP3Tagger but for video files?

  • Why is a DataViewManager not sorting?

    - by Alarion
    First off, a quick rundown of what the code is doing. I have two tables: Companies and Clients. There is a one to many relationship between Companies and Clients (one company can have many clients). In some processing logic, I have both tables loaded into a DataSet - each are DataTables. I have added a DataRelation to set the relationship, and it works when I use GetChildRows on a record from the Companies table. However, I need to sort the records returned. After googling around some it looks like the DataViewManager is the way to go, and I have examined several basic examples. However, I cannot get my rows sorted. Am I missing something, or am I not using this how it is supposed to be used? Example code: Dim ldvmManager As New DataViewManager(mdsData) ldvmManager.DataViewSettings("Companies").Sort = "comName ASC" ldvmManager.DataViewSettings("Clients").ApplyDefaultSort = False ldvmManager.DataViewSettings("Clients").Sort = "entLastName ASC, entFirstName ASC" For Each mdrCurrentCompany in ldvmManager.DataViewSettings("Companies").Table.Rows Dim ldrClients() as DataRow = mdrCurrentCompany.GetChildRows("CompaniesClients") Next No matter what I do, the first Client returned has a last name that starts with a 'B' and the second has one that starts with a 'A'. From there, the order is all mixed up. If I use my entire data instead of the subset I was using to test with, the first Client returned has a last name that starts with 'J'. It seems like it is still using whatever default sort was being used before I tried to use the DataViewManager. Any ideas?

  • Build system for multi-language project

    - by Epcylon
    I am getting ready to embark on a project mainly for experimenting with languages, but also with a hint of usefulness. It will consist of a server-application, written in Erlang, and client-libraries in a number of languages. Initially I will want to write clients in Java, Ruby and Python. The actual protocol for communication will be Thrift. I'm looking for a build system that will allow me to build the server and all the client libraries in one go, running unit-tests in each language, then packaging up a releasable artifact of some sort in whatever way is the "standard" for each language. That means a Jar for Java, a RubyGem and a distribute/setuptools tarball for Python. Erlang probably has something too, but I'm not yet familiar with that. It should also be able to run the Thrift compiler to generate the various Thrift-stubs in each language. On the pad at the start is Maven. I'm fairly certain Maven can do all I need, but I fear it's too Java-centric, and leaves me with a ton of work for every new language I need to add.

  • Java: Allowing the child thread to kill itself on InterruptedException?

    - by Zombies
    I am using a ThreadPool via ExecutorService. By calling shutDownNow() it interrupts all running threads in the pool. When this happens I want these threads to give up their resources (socket and db connections) and simply die, but without continuing to run anymore logic, eg: inserting anything into the DB. What is the simplest way to achieve this? Bellow is some sample code: public void threadTest() { Thread t = new Thread(new Runnable() { public void run() { try { Thread.sleep(999999); } catch (InterruptedException e) { //invoke thread suicide logic here } } }); t.start(); t.interrupt(); try { Thread.sleep(4000); } catch (InterruptedException e) { } }

  • Writing data into New NFC Tag not works?

    - by Nagaraj436
    I am Newbie to NFC Android App Development. I am done with the App development and everything worked fine. As part of my testing I used MifareClassic as well MifareDesfire tags to write and read. I am storing data in Ndef format. Initially I used the above testing tags with other apps like Nxp tagwriter and Tagstand Tagwriter and then I used with My app. So everything worked fine. Even later I used my app to write and read data from Sony Felica tags(new tags) which also worked fine. So I passed app to client for review but I came to know that app is not writing on New Tags. If they are reset from other apps then It works fine. So I done the same test here and found the same issue as client reported. What might be the issue? Has someone come across same kind of issue? Is it required to format before using? if so how to do that? Someone Help to solve the issue. Thanks in Advance.

  • Passing contextual info to Views in ASP.NET MVC

    - by Andrey
    I wonder - what is the best way to supply contextual (i.e. not related to any particular view, but to all views at the same time) info to a view (or to master page)? Consider the following scenario. Suppose we have an app that supports multiple UI languages. User can switch them via UI's widgets (something like tabs at the top of the page). Each language is rendered as a separate tab. Tab for the current language should not be rendered. To address these requirements I'm planning to have a javascript piece that will hide current's language tab on the client. To do this, I need current's language tab Id on the client. So, I need some way of passing the Id to master page (for it to be 'fused' into the js script). The best thing I can think of is that all my ViewModels should inherit some ViewModeBase that has a field to hold current language tab Id. Then, whatever View I'm rendering, this Id will always be available for the master page's hiding script. However, I'm concerned that this ViewModelBase can potentially grow in an uncontrolled fashion as number of such pieces of contextual info (like current language) will grow.. Any ideas?

  • Java Or C++ Or What???

    - by Kronass
    Hi, My friends and I are starting a new project and we are shifting from windows to linux (for some reasons) and all of us are .Net background. for the new platform I decided to go with Java since many parts are similar with .Net but my friend is insisting on C++ saying it is much faster very mature and working with it will not effect on the productivity and development speed. The project that we will work on it will have threading, extensive string and datetime manipulation, some socket programing and of-course work with RDBMS (MySql Or Postgre not decided yet). I have some fears with java since oracle acquired sun and these people will do anything to make money out of it. some have advised in python and ruby and I like python but don't know should I make it the default language in this project. the project is not web application and we will make services and executables. what do you think, if you have other opinion you very welcome. Hint: Mono is not an option

  • How to Check Authenticity of an AJAX Request

    - by Alex Reisner
    I am designing a web site in which users solve puzzles as quickly as they can. JavaScript is used to time each puzzle, and the number of milliseconds is sent to the server via AJAX when the puzzle is completed. How can I ensure that the time received by the server was not forged by the user? I don't think a session-based authenticity token (the kind used for forms in Rails) is sufficient because I need to authenticate the source of a value, not just the legitimacy of the request. Is there a way to cryptographically sign the request? I can't think of anything that couldn't be duplicated by a hacker. Is any JavaScript, by its exposed, client-side nature, subject to tampering? Am I going to have to use something that gets compiled, like Flash? (Yikes.) Or is there some way to hide a secret key? Or something else I haven't thought of? Update: To clarify, I don't want to penalize people with slow network connections (and network speed should be considered inconsistent), so the timing needs to be 100% client-side (the timer starts only when we know the user can see the puzzle). Also, there is money involved so no amount of "trusting the user" is acceptable.

  • .NET - Unable to get values from Value property of HtmlInputHidden

    - by user245123
    I have a custom control that inherits from .NET's CompositeControl class. This control overrides the CreateChildControls in order to build its child controls dynamically. I need the page to post back after a couple different javascript events occur on the client side. In order to accomplish this, I create two hidden controls on the page so I can set their values with javascript, submit the page, and read the values out on server side. Here's is the code I use to create these two hiddens: Protected Overrides Sub CreateChildControls() hdEventName = New HiddenField() Controls.Add(hdEventName) hdEventName.ID = "hdEventName" hdEventArgs = New HiddenField() Controls.Add(hdEventArgs) hdEventArgs.ID = "hdEventValue" ' other controls ' ... End Sub When a javascript event occurs I set the value attribute of the two hiddens and submit the page, like so: hdEventName.value = 'EventName'; hdEventArgs.value = 'arg1,arg2'; document.forms[0].submit(); In the OnLoad method of my control, I attempt to check the Value property of the hdEventName and hdEventArgs controls, but it is always empty. However, Page.Request.Form(hdEventName.UniqueID) and Page.Request.Form(hdEventArgs.UniqueID) return correct values. The actual HTML in the markup also shows correct values after the page posts back. Why is the Value property of the HtmlInputHiddens disconnected from the actual value that appears on the client?

  • C# WCF and Object Inheritence

    - by Michael Edwards
    I have the following setup of two classes: [SerializableAttribute] public class ParentData{ [DataMember] public string Title{get;set;} } [DataContract] public class ChildData : ParentData{ [DataMember] public string Abstract{get;set;} } These two classes are served through a WCF service. However I only want the service to expose the ChildData class to the end user but pull the marked up DataMember properties from the parent. E.g. The consuming client would have a stub class that looked like: public class ChildData{ public string Title{get;set;} public string Abstract{get;set;} } If I uses the parent and child classes as above the stub class only contains the Abstract property. I have looked at using the KnownType attribute on the ChildData class like so: [DataContract] [KnownType(typeOf(ParentData)] public class ChildData : ParentData{ [DataMember] public string Abstract{get;set;} } However this didn't work. I then applied the DataContract attribute to the ParentData class, however this then creates two stub classes in the client application which I don't want. Is there any way to tell the serializer that it should flatten the inheritance to that of the sub-class i.e. ChildData

  • Custom ADO.NET provider to intercept and modify sql queries.

    - by Faisal
    Our client has an application that stores blobs in database which has now grown enough to impact the performance of SQL Server. To overcome this issue, we are planning to offload all blobs to file system and leave the path of file in a new column in user table. Like if user has a table docs with columns id, name and content (blob); we would ask him to add a new column 'filepath' in this table. Our client is willing to make this change in this database. But when it comes to changing the sql queries to read and write into this table, they are not ready to accep this. Actually, they don't want any change that results in recompilation and deployment. Now we are planning to write a custom ADO.NET provider that will intercept the select queries add a column 'filepath' at the end of the select statement retieve the result set and modify the 'content' column value based on 'filepath' value Is there any use case that you think will certainly fail with this approach? I know this sounds dirty but do we have a better way?

  • "date_part('epoch', now() at time zone 'UTC')" not the same time as "now() at time zone 'UTC'" in po

    - by sirlark
    I'm writing a web based front end to a database (PHP/Postgresql) in which I need to store various dates/times. The times are meant to be always be entered on the client side in the local time, and displayed in the local time too. For storage purposes, I store all dates/times as integers (UNIX timestamps) and normalised to UTC. One particular field has a restriction that the timestamp filled in is not allowed to be in the future, so I tried this with a database constraint... CONSTRAINT not_future CHECK (timestamp-300 <= date_part('epoch', now() at time zone 'UTC')) The -300 is to give 5 minutes leeway in case of slightly desynchronised times between browser and server. The problem is, this constraint always fails when submitting the current time. I've done testing, and found the following. In PostgreSQL client: SELECT now() -- returns correct local time SELECT date_part('epoch', now()) -- returns a unix timestamp at UTC (tested by feeding the value into the date function in PHP correcting for its compensation to my time zone) SELECT date_part('epoch', now() at time zone 'UTC') -- returns a unix timestamp at two time zone offsets west, e.g. I am at GMT+2, I get a GMT-2 timestamp. I've figured out obviously that dropping the "at time zone 'UTC'" will solve my problem, but my question is if 'epoch' is meant to return a unix timestamp which AFAIK is always meant to be in UTC, why would the 'epoch' of a time already in UTC be corrected? Is this a bug, or I am I missing something about the defined/normal behaviour here.
