• Can't transfer list<T> to web service?

  - by iTayb

  I have the same classes on my server and on my web service. I have the following WebMethod: [WebMethod] public int CreateOrder(List<Purchase> p, string username) { o.Add(new Order(p,username)); return o.Count; } However the following code, run at server: protected void CartRepeater_ItemCommand(object source, RepeaterCommandEventArgs e) { List<Purchase> l = ((List<Purchase>)Session["Cart"]); if (e.CommandName == "Order") { localhost.ValidateService WS = new localhost.ValidateService(); WS.CreateOrder(l, Session["username"].ToString()); } } gives the following error: Argument '1': cannot convert from 'System.Collections.Generic.List<Purchase>' to 'localhost.Purchase[]'. How can I transfer the list<Purchase> object to the web service? Thank you very much.

• Tomcat gzip while chunked issue

  - by hoodoos

  I'm expiriencing some problem with one of my data source services. As it says in HTTP response headers it's running on Apache-Coyote/1.1. Server gives responses with Transfer-Encoding: chunked, here sample response: HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Content-Type: text/xml;charset=utf-8 Transfer-Encoding: chunked Content-Encoding: gzip Date: Tue, 30 Mar 2010 06:13:52 GMT And problem is when I'm requesting server to send gzipped request it often sends not full response. I recieve response, see that last chunk recieved, but then after ungzipping I see that response is partial. I never seen such behavior with gzip turned off in request headers. So my question is: is it common tomcat issue? maybe one of it's mod which is doing compression? Or maybe it maybe some kind of proxy issue? I can't tell about versions of tomcat or what gzip mod they use, but feel free to ask, i'll try ask my service provider. Thanks.

• transfer files with ftp with ftpwebrequest

  - by Dejan.S

  Hi. currently I'm working on this ftp transfer. http://msdn.microsoft.com/en-us/library/ms229715.aspx I have setup my server computers iis to have a ftp site on port 21 and transfering files works great. But I want to add ftp to a hosted site I got on the server and it's here where I get the problems with connecting. when I try to connect through the command promt I get unknown host error. I have changed the port and open it up in firewall. and even if I could connect how can I decide what folder I want to upload to?

• Programatically determining maximum transfer rate

  - by dauphic

  I have a problem that requires me to calculate the maximum upload and download available, then limit my program's usage to a percentage of it. However, I can't think of a good way to find the maximums. At the moment, the only solution I can come up with is transfering a few megabytes between the client and server, then measuring how ling the transfer took. This solution is very undesirable, however, because with 100,000 clients it could potentially result in too much of an increase to our server's bandwidth usage (which is already too high). Does anyone have any solutions to this problem?

• java best way to transfer images

  - by d.raev

  I have a application that reads a PDF, transform the content to collection of TIF files, and send them to Glass Fish Server for saving. Usually there are 1-5 pages and it works nice, but when I got a input file with 100+ pages... it throws error on the transfer. Java heap space at java.util.Arrays.copyOf(Arrays.java:2786) at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:94) Putting more resources is not a good option in my case, so I m looking for a way to optimize it somehow. I store the data in: HashMap<TifProfile, List<byte[]> Is there a better way to store or send them ? EDIT I did some tests and the final collections for PDF with 80 pages has size over 280mb (240 tiffs with different settings inside)

• Transfer of directory structure over network

  - by singh

  I am designing a remote CD/DVD burner to address hardware constraints on my machine. My design works like this: (analogous to a network printer) Unix-based machine (acts as server) hosts a burner. Windows-based machine acts as client. Client prepares data to burn and transfers it to the server. Server burns the data on CD/DVD. My question is: what is the best protocol to transfer data over the network (Keeping the same directory hierarchy) between different operating systems?

• Asp.Net : IHttpModule + m_context.Server.Transfer = session state error

  - by tinky05

  I have an IHttpModule that implements IRequiresSessionState. The session state is at "on" on the page directive and I also added it to the web.config. In the method "OnBeginRequest" in the IHttpModule, I make a Server.Transfer but I get the error : Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. When I access the page directly or with a Response.Redirect, there is no error. Any idea? Update : The error occur in a page extending System.Web.UI.Page in the method InitializeCulture() which is an override.

• Server.Transfer - What could be the issue here?

  - by Younes

  We have implemented a website with the ability for the user to post his actioncode. This then will be checked by the code and when the user has a price the website will Server.Transfer him to another page. The strange thing here is that the user information will be submitted to the database and the actioncode can't be used again. Here we go... I have one user in this database that is inserted twice very fast after the first time he was added. This are the timestamps: 2010-04-23 07:54:41.133 2010-04-23 07:54:41.417 The insert statement is only called once from the code and the user gets Server.Transfered to the Price.aspx page where he sees what price he won. How can it be that this happened? I'm guessing the user hitted F5 but then he had to be very very fast... Thx!

• Why am I getting such slow file transfer performance?

  - by kingdango

  Copying 4GB from a USB flash drive to my Linux partition. The flash drive is NTFS formatted (I believe, it's Windows formatted). The transfer is incredibly slow and blocks the computer frequently causing lag and hanging applications. My transfer rate is 1.2 MB/sec and that is the max it has hit when I let the File Operations window have focus. Why is this so slow under Ubuntu and significantly faster in Win 7?

• Apache on Win32: Slow Transfers of single, static files in HTTP, fast in HTTPS

  - by Michael Lackner

  I have a weird problem with Apache 2.2.15 on Windows 2000 Server SP4. Basically, I am trying to serve larger static files, images, videos etc. The download seems to be capped at around 550kB/s even over 100Mbit LAN. I tried other protocols (FTP/FTPS/FTP+ES/SCP/SMB), and they are all in the multi-megabyte range. The strangest thing is that, when using Apache with HTTPS instead of HTTP, it serves very fast, around 2.7MByte/s! I also tried the AnalogX SimpleWWW server just to test the plain HTTP speed of it, and it gave me a healthy 3.3Mbyte/s. I am at a total loss here. I searched the web, and tried to change the following Apache configuration directives in httpd.conf, one at a time, mostly to no avail at all: SendBufferSize 1048576 #(tried multiples of that too, up to 100Mbytes) EnableSendfile Off #(minor performance boost) EnableMMAP Off Win32DisableAcceptEx HostnameLookups Off #(default) I also tried to tune the following registry parameters, setting their values to 4194304 in decimal (they are REG_DWORD), and rebooting afterwards: HKLM\SYSTEM\CurrentControlSet\Services\AFD\Parameters\DefaultReceiveWindow HKLM\SYSTEM\CurrentControlSet\Services\AFD\Parameters\DefaultSendWindow Additionally, I tried to install mod_bw, which sets the event timer precision to 1ms, and allows for bandwidth throttling. According to some people it boosts static file serving performance when set to unlimited bandwidth for everybody. Unfortunately, it did nothing for me. So: AnalogX HTTP: 3300kB/s Gene6 FTPD, plain: 3500kB/s Gene6 FTPD, Implicit and Explicit SSL, AES256 Cipher: 1800-2000kB/s freeSSHD: 1100kB/s SMB shared folder: about 3000kB/s Apache HTTP, plain: 550kB/s Apache HTTPS: 2700kB/s Clients that were used in the bandwidth testing: Internet Explorer 8 (HTTP, HTTPS) Firefox 8 (HTTP, HTTPS) Chrome 13 (HTTP, HTTPS) Opera 11.60 (HTTP, HTTPS) wget under CygWin (HTTP, HTTPS) FileZilla (FTP, FTPS, FTP+ES, SFTP) Windows Explorer (SMB) Generally, transfer speeds are not too high, but that's because the server machine is an old quad Pentium Pro 200MHz machine with 2GB RAM. However, I would like Apache to serve at at least 2Mbyte/s instead of 550kB/s, and that already works with HTTPS easily, so I fail to see why plain HTTP is so crippled. I am using a Kerio Winroute Firewall, but no Throttling and no special filters peeking into HTTP traffic, just the plain Firewall functionality for blocking/allowing connections. The Apache error.log (Loglevel info) shows no warnings, no errors. Also nothing strange to be seen in access.log. I have already stripped down my httpd.conf to the bare minimum just to make sure nothing is interfering, but that didn't help either. If you have any idea, help would be greatly appreciated, since I am totally out of ideas! Thanks! Edit: I have now tried a newer Apache 2.2.21 to see if it makes any difference. However, the behaviour is exactly the same. Edit 2: KM01 has requested a sniff on the HTTP headers, so here comes the LiveHTTPHeaders output (an extension to Firefox). The Output is generated on downloading a single file called "elephantsdream_source.264", which is an H.264/AVC elementary video stream under an Open Source license.

• How to transfer objects through the header in WCF

  - by Michael

  I'm trying to transfer some user information in the header of the message through message inspectors. I have created a behavior which adds the inspector to the service (both client and server). But when I try to communicate with the service I get the following error: XmlException: Name cannot begin with the '<' character, hexadecimal value 0x3C. I have also get exception telling me that DataContracts where unexpected. Type 'System.DelegateSerializationHolder+DelegateEntry' with data contract name 'DelegateSerializationHolder.DelegateEntry:http://schemas.datacontract.org/2004/07/System' is not expected. Consider using a DataContractResolver or add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer. The thing is that my object contains other objects which are marked as DataContract and I'm not interested adding the KnownType attribute for those types. Another problem might be that my object to serialize is very restricted in form of internal class and internal properties etc. Can anyone guide me in the right direction. What I'm I doing wrong? Some code: public virtual object BeforeSendRequest(ref Message request, IClientChannel channel) { var header = MessageHeader.CreateHeader("<name>", "<namespace>", object); request.Headers.Add(header); return Guid.NewGuid(); }

• Using both chunked transfer encoding and gzip

  - by RadiantHeart

  I recently started using gzip on my site and it worked like charm on all browsers except Opera which gives an error saying it could not decompress the content due to damaged data. From what I can gather from testing and googling it might be a problem with using both gzip and chunked transfer encoding. The fact that there is no error when requesting small files like css-files also points in that direction. Is this a known issue or is there something else that I havent thought about? Someone also mentioned that it could have something to do with sending a Content-Length header. Here is a simplified version of the most relevant part of my code: $contents = ob_get_contents(); ob_end_clean(); header('Content-Encoding: '.$encoding); print("\x1f\x8b\x08\x00\x00\x00\x00\x00"); $size = strlen($contents); $contents = gzcompress($contents, 9); $contents = substr($contents, 0, $size); print($contents); exit();

• Secure Password Storage and Transfer

  - by Andras Zoltan

  I'm developing a new user store for my organisation and am now tackling password storage. The concepts of salting, HMAC etc are all fine with me - and want to store the users' passwords either salted and hashed, HMAC hashed, or HMAC salted and hashed - not sure what the best way will be - but in theory it won't matter as it will be able to change over time if required. I want to have an XML & JSON service that can act as a Security Token Service for client-side apps. I've already developed one for another system, which requires that the client double-encrypts a clear-text password using SHA1 first and then HMACSHA1 using a 128 unique key (or nonce) supplied by the server for that session only. I'd like to repeat this technique for the new system - upgrading the algo to SHA256 (chosen since implementations are readily available for all aforementioned platforms - and it's much stronger than SHA1) - but there is a problem. If I'm storing the password as a salted hash in the user-store, the client will need to be sent that salt in order to construct the correct hash before being HMACd with the unique session key. This would completely go against the point of using a salt in the first place. Equally, if I don't use salt for password storage, but instead use HMAC, it's still the same problem. At the moment, the only solution I can see is to use naked SHA256 hashing for the password in the user store, so that I can then use this as a starting point on both the server and the client for a more secure salted/hmacd password transfer for the web service. This still leaves the user store vulnerable to a dictionary attack were it ever to be accessed; and however unlikely that might be - assuming it will never happen simply doesn't sit well with me. Greatly appreciate any input.

• How do I create a dynamic data transfer object dynamically from ADO.net model

  - by Richard

  I have a pretty simple database with 5 tables, PK's and relationships setup, etc. I also have an ASP.net MVC3 project I'm using to create simple web services to feed JSON/XML to a mobile app using post/get. To access my data I'm using an ADO.net entity model class to handle generation of the entities, etc. Due to issues with serialization/circular references created by the auto-generated relations from ADO.net entity model, I've been forced to create "Data transfer objects" to strip out the relations and data that doesn't need to be transferred. Question 1: is there an easier way to create DTOs using the entity framework itself? IE, specify only the entity properties I want to convert to Jsonresults? I don't wish to use any 3rd party frameworks if I can help it. Question 2: A side question for Entity Framework, say I create an ADO.net entity model in one project within a solution. Because that model relies on the connection to the database specified in project A, can project B somehow use that model with a similar connection? Both projects are in the same solution. Thanks!

• Python: How to transfer varrying length arrays over a network connection

  - by Devin

  Hi, I need to transfer an array of varying length in which each element is a tuple of two integers. As an example: path = [(1,1),(1,2)] path = [(1,1),(1,2),(2,2)] I am trying to use pack and unpack, however, since the array is of varying length I don't know how to create a format such that both know the format. I was trying to turn it into a single string with delimiters, such as: msg = 1&1~1&2~ sendMsg = pack("s",msg) or sendMsg = pack("s",str(msg)) on the receiving side: path = unpack("s",msg) but that just prints 1 in this case. I was also trying to send 4 integers as well, which send and receive fine, so long as I don't include the extra string representing the path. sendMsg = pack("hhhh",p.direction[0],p.direction[1],p.id,p.health) on the receive side: x,y,id,health = unpack("hhhh",msg) The first was for illustration as I was trying to send the format "hhhhs", but either way the path doesn't come through properly. Thank-you for your help. I will also be looking at sending a 2D array of ints, but I can't seem to figure out how to send these more 'complex' structures across the network. Thank-you for your help.

• How do you know when you should change the programming domain you're working in?

  - by thecoop

  I've recently become one of the most senior developers in one division of the company, and am generally the 'go-to' guy about questions in the problem domain the division works in, however I feel I'm not learning anything new. To continue to learn new things I would have to change division and work on something competely different, but then my current domain knowledge would be useless & I would start off with knowing nothing again. Obviously, this is quite a large decision & I'm hesitant to lost my 'status'; and the knowledge I do have would be useless. How do you know when you should change the programming domain you work in?

• PHP Redirection with Post Parameters

  - by arik-so

  Hello, I have a webpage. This webpage redirects the user to another webpage, more or less the following way: <form method="post" action="anotherpage.php" id="myform"> <?php foreach($_GET as $key => $value){ echo "<input type='hidden' name='{$key}' value='{$value}' />"; } ?> </form> <script> document.getElementById('myform').submit(); </script> Well, you see, what I do is transferring the GET params into POST params. Do not tell me it is bad, I know that myself, and it is not exactly what I really do, what is important is that I collect data from an array and try submitting it to another page via POST. But if the user has JavaScript turned off, it won't work. What I need to know: Is there a way to transfer POST parameters by means of PHP so the redirection can be done the PHP way (header('Location: anotherpage.php');), too? It is very important for me to pass the params via POST. I cannot use the $_SESSION variable because the webpage is on another domain, thus, the $_SESSION variables differ. Anyway, I simply need a way to transfer POST variables with PHP ^^ Thanks in advance!

There could be the situation when I update the image by editing the image and upload it with same name, now in this case the image file would be already present there, which will restrict the use of "file_exist" logic, so for these type of situations....HOW CAN I COMPARE THE TWO FILE STRUCTURE TO GET THE SYNCHRONIZATION DONE AS PER REQUIREMENT??

• Idiomatic use of auto_ptr to transfer ownership to a container

  I'm refreshing my C++ knowledge after not having used it in anger for a number of years. In writing some code to implement some data structure for practice, I wanted to make sure that my code was exception safe. So I've tried to use std::auto_ptrs in what I think is an appropriate way. Simplifying somewhat, this is what I have: class Tree { public: ~Tree() { /* delete all Node*s in the tree */ } void insert(const string& to_insert); ... private: struct Node { ... vector<Node*> m_children; }; Node* m_root; }; template<T> void push_back(vector<T*>& v, auto_ptr<T> x) { v.push_back(x.get()); x.release(); } void Tree::insert(const string& to_insert) { Node* n = ...; // find where to insert the new node ... push_back(n->m_children, auto_ptr<Node>(new Node(to_insert)); ... } So I'm wrapping the function that would put the pointer into the container, vector::push_back, and relying on the by-value auto_ptr argument to ensure that the Node* is deleted if the vector resize fails. Is this an idiomatic use of auto_ptr to save a bit of boilerplate in my Tree::insert? Any improvements you can suggest? Otherwise I'd have to have something like: Node* n = ...; // find where to insert the new node auto_ptr<Node> new_node(new Node(to_insert)); n->m_children.push_back(new_node.get()); new_node.release(); which kind of clutters up what would have been a single line of code if I wasn't worrying about exception safety and a memory leak. (Actually I was wondering if I could post my whole code sample (about 300 lines) and ask people to critique it for idiomatic C++ usage in general, but I'm not sure whether that kind of question is appropriate on stackoverflow.)

• Is it possible to transfer a domain without a "gap" in Whois privacy protection?

  - by Guest

  I currently own several domains on which I am using a Whois privacy protection service to hide my personal details. In the near future, I would like to transfer some of these domains to a different registrar. It has been many years since I last performed domain transfers, so I am no longer knowledgeable about what it involves. However, I have read from several registrars that they ask their customers to disable Whois protection before effecting a domain transfer. Since there are several websites out there that publish archived versions of Whois information (and ask handsome money for the information to be hidden, of course), I would prefer to avoid having such a "gap" in my privacy protection. I figured that these websites would fetch Whois information mainly when a query is effected through their own website. However, I have found out that at least one of these sites had a copy of the Whois information for a new domain up on their site within hours after I registered it, so they must have some other source (of course I used a Google search to find that out, not their own site). What that tells me is that the time it takes for the domain transfers to go through would be more than enough for these rogue websites to cache my information. If my new registrar offers privacy protection for domains right from the point of registration as well, is there no way to transfer the domain between the two without reverting to my default Whois information in between?
