• SocketAsyncEventArgs and buffering while messages are in parts

  - by Rob

  C# socket server, which has roughly 200 - 500 active connections, each one constantly sending messages to our server. About 70% of the time the messages are handled fine (in the correct order etc), however in the other 30% of cases we have jumbled up messages and things get screwed up. We should note that some clients send data in unicode and others in ASCII, so that's handled as well. Messages sent to the server are a variable length string which end in a char3, it's the char3 that we break on, other than that we keep receiving data. Could anyone shed any light on our ProcessReceive code and see what could possibly be causing us issues and how we can solve this small issue (here's hoping it's a small issue!) Code below:

• Stored Procedure with ALTER TABLE

  - by psayre23

  I have a need to sync auto_increment fields between two tables in different databases on the same MySQL server. The hope was to create a stored procedure where the permissions of the admin would let the web user run ALTER TABLE [db1].[table] AUTO_INCREMENT = [num]; without giving it permissions (That just smells of SQL injection). My problem is I'm receiving errors when creating the store procedure. Is this something that is not allowed by MySQL? DROP PROCEDURE IF EXISTS sync_auto_increment; CREATE PROCEDURE set_auto_increment (tableName VARCHAR(64), inc INT) BEGIN ALTER TABLE tableName AUTO_INCREMENT = inc; END;

• Read OAuth2.0 Signed_Request Facebook Registration C# MVC

  - by Josh

  My question is very similar this but I guess I need to take it one step further. Facebook says "The data is passed to your application as a signed request. The signed_request parameter is a simple way to make sure that the data you're receiving is the actual data sent by Facebook." After a user has logged into my asp c# MVC site and clicked "Register", the redirect-url is http://site/account/register. At that point (the post to the account/register control), I would like to gather the user's information using the signed request so that I can register them with my site locally. I cannot figure out how to access the data facebook makes available. $data = json_decode(base64_url_decode($payload), true); What is the equivalent in C#? What type of variable/data is facebook passing in the post? And how do I access "$payload"?

• Use WM_COPYDATA to send data between processes

  - by Charles Gargent

  I wish to send text between processes. I have found lots of examples of this but none that I can get working. Here is what I have so far: for the sending part: COPYDATASTRUCT CDS; CDS.dwData = 1; CDS.cbData = 8; CDS.lpData = NULL; SendMessage(hwnd, WM_COPYDATA , (WPARAM)hwnd, (LPARAM) (LPVOID) &CDS); the receiving part: case WM_COPYDATA: COPYDATASTRUCT* cds = (COPYDATASTRUCT*) lParam; I dont know how to construct the COPYDATASTRUCT, I have just put something in that seems to work. When debugging the WM_COPYDATA case is executed, but again I dont know what to do with the COPYDATASTRUCT. I would like to send text between the two processes. As you can probably tell I am just starting out, I am using GNU GCC Compiler in Code::Blocks, I am trying to avoid MFC and dependencies.

• Socket programming and telnet with VB.net

  - by Mike

  I'm writing a GUI-based app in VB.net that talks to a LambdaMOO server via telnet, sends commands to display the object hierarchy, then parses the output and creates a visual representation of the object hierarchy. So my question is: is there some kind of "telnet client" class for .NET to simplify the sending and receiving of data, or do I have to write my own using the socket API? Does Mono have something like this? Barring an easy solution, does anyone have a good tutorial they can point to for telnet client programming in VB.net?

  - by Rafal

  Hi I have a problem during insert to database by LINQ command in WCF Service from Silverlight application. Receiving data works fine - select works in LINQ and shows data from database(sql server 2008). When i try to insert data, the Error ocures: System.Net.WebException: The remote server returned an error: NotFound. ---> System.Net.WebException: The remote server returned an error: NotFound. at System.Net.Browser.BrowserHttpWebRequest.InternalEndGetResponse(IAsyncResult asyncResult) at System.Net.Browser.BrowserHttpWebRequest.<>c__DisplayClass5.<EndGetResponse>b__4(Object sendState) at System.Net.Browser.AsyncHelper.<>c__DisplayClass2.<BeginOnUI>b__0(Object sendState) --- End of inner exception stack trace --- at System.Net.Browser.AsyncHelper.BeginOnUI(SendOrPostCallback beginMethod, Object state) at System.Net.Browser.BrowserHttpWebRequest.EndGetResponse(IAsyncResult asyncResult) at System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelAsyncRequest.CompleteGetResponse(IAsyncResult result)} It looks the same, when i had a wrong ClientConfig/Web.config file.

• Transferring Data Directly between 2 Connections in Indy (TIdContext)

  - by killercode

  ive a sever running TIdTCPServer, and Client Using Web Browser (or any other software) to Communicate, i dunno the protocol, but what im trying to do is to Send The Data between the client and another Connection (Both Connected to the same TIdTCPServer) for example the data sent by the first client is transmitted to the second client, and the data sent by the second client is transmitted to the first client, like a proxy (i cant really use a proxy server since its just this one condition) and the TIdTCPServer should still be receiving other clients and processing their data. i stumbled upon the first line of code, since TIdContext.Connection.Socket.ReadLn requires a Delimiter, and the Client's Protocol is unknown to the server. any ideas? thanks.

• Using gmail as SMTP server in Java web app is slow

  - by Annie

  Hi, I was wondering if anyone might be able to explain to me why it's taking nearly 30 seconds each time my Java web app sends an email using Gmail's SMTP server? See the following timestamps: 13/04/2010-22:24:27:281 DEBUG test.service.impl.SynchronousEmailService - Before sending mail. 13/04/2010-22:24:52:625 DEBUG test.service.impl.SynchronousEmailService - After sending mail. I'm using spring's JavaMailSender class with the following settings: email.host=smtp.gmail.com [email protected] email.password=mypassword email.port=465 mail.smtp.auth.required=true Note that the mail is getting sent and I'm receiving it fine, there's just this delay which is resulting in a slow experience for the application user. If you know how I can diagnose the problem myself that would be good too :)

• receive emails in a .NET service (C#)

  - by Jean Azzopardi

  Hi, this is my first posting on stackoverflow, so don't flame me too much ;) I'm building a service that's monitoring devices and should be able to receive emails from users, parse them and take action accordingly. It should also be able to send emails about the status of the devices, etc. I'll be using Windows.Live email, and as I said, a .NET service that should be able to send/recieve emails. I am wondering what kind of system would I need to cater for receiving the emails, as I already know how to send them via the System.net.Mail API. Thanks. EDIT : Thanks for your comments everybody, I'm looking forward to implementing this system and asking more questions on this rather excellent site.

• Ora-01000 - maximum open cursors exceeded error

  - by PeteDaMeat

  I am receiving the following error message within my Delphi/Oracle application "ora-01000 - maximum open cursors exceeded". The code is as follows: begin for i := 0 to 150 do begin with myADOQuery do begin SQL.Text := 'DELETE FROM SOMETABLE'; ExecSQL; -- from looking at V$OPEN_CURSOR a new cursor is added on each iteration for the session Close; -- thought this would close the cursor but doesn't end; end; end; I'm aware I can resolve the problem by simply increasing the number of OPEN_CURSORS parameters, however, I would rather find a solution whereby the cursor is closed after the query is executed. Any ideas? Delphi 2006 BDS Oracle 10g

• OpenID token from Google (using www)?

  - by MunkiPhD

  I've come across the following situation when using OpenID and Google as the authenticator. If you type siteName.com it takes you to http://sitename.com Which returns a different token than if I were to login to www.siteName.com, which would take me to http://www.siteName.com As a result, Google returns a different authentication token. Is there a simple fix around this? Maybe redirect the user from siteName.com to www.siteName.com? Would this be a server issue, or is this something I can do programmatically? Thanks in advance for any answers, this question had plagued me for some time now as I just figured out why others had been receiving different credentials upon logging in.

• How should I use color in my application? Single, Theme, or Chaos?

  - by CodeSlave

  How should I be using color in my application? I have over a 100 different forms (windows) in my application, and the default windows grey seems like a bad choice to me. One school of thought says pick one neutral color, and use the same one everywhere. Another school of thought says pick a set of neutral colors, and use them same ones within a group of form (e.g., shipping screens might be light green, receiving screens light orange, user administration screens light blue, etc.). The final school of thought says make every form different. We've got millions of colors, why not use them? What should I do and why?

• How to upload binary (audio) data from a Flash AS3 client to .NET server (WCF/REST/HTTP/?)?

  - by Bobby

  Simply stated: I'm trying to record audio in a browser, and get that data back up to the server. I originally tried to capture, encode and upload the audio using Silverlight, but because of the lack of suitable client-side encoding options, I'm now giving Flash a shot (Flash has baked-in support for encoding to Speex). I think I've figured out how to capture and encode the audio... But now what was easy in Silverlight, is the challenge in Flash. My server-side is .NET: MVC2- I'm open to receiving the audio in whatever manner is best- REST, WCF.. So that's my question: How could one upload binary data from Flash, to a .NET server-side endpoint. If the answer is WCF: then how would one setup the client-side proxies to communicate with the service? If the answer is REST or HTTP Post, then how would one construct this HTTP request and pass along the data? I've been reading up on AS3, but am new to Flash dev... Thanks for any help!

• RSpec: Expectation on model's not working while testing controller

  - by gmile

  I'm trying to write a functional test. My test looks as following: describe PostsController do it "should create a Post" do Post.should_receive(:new).once post :create, { :post => { :caption => "ThePost", :category => "MyCategory" } } end end My PostsController (a part of it actually) looks as following: PostController < ActiveRecord::Base def create @post = Post.new(params[:post]) end end Running the test I'm always receiving a failure, which says that the Post class expected :new but never got it. Still, the actual post is created. I'm a newbie to RSpec. Am I missing something?

• Troubleshooting MSSQL Connection from PHP

  - by Cory Dee

  I'm trying to connect to an external Sql Server through PHP 5.2. Using this line: $con = mssql_connect('123.123.123.123','Username','Password') or die('Could not connect to the server!'); I'm receiving this error: Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server: 123.123.123.123 in /home/file/public_html/structure/index.php on line 4 Could not connect to the server! My hosting provider assures me that ports are open for my server to connect to the DB. Looking at my php info, MSSQL Support is enabled, using FreeTDS. Any ideas why this would be failing, or how I can begin trouble shooting the problem?

• Stopping httpd causes a process started from perl CGI script to receive SIGTERM

  - by Pranav Pal

  I am running a shell script from a perl CGI script: #!/usr/bin/perl my $command = "./script.sh &"; my $pid = fork(); if (defined($pid) && $pid==0) { # background process system( $command ); } The shell script looks like this: #!/bin/sh trap 'echo trapped' 15 tail -f test.log When I run the CGI script from browser, and then stop httpd using /etc/init.d/httpd stop, the script receives a SIGTERM signal. I was expecting the script to run as a separate process and not be tied in anyway to httpd. Though I can trap the SIGTERM, I would like to understand why the script is receiving SIGTERM at all. What wrong am I doing here? I am running RHEL 5.8 and Apache HTTP server 2.4. Thanks, Pranav

• Will there be IQueryable-like additions to IObservable? (.NET Rx)

  - by Jason

  The new IObservable/IObserver frameworks in the System.Reactive library coming in .NET 4.0 are very exciting (see this and this link). It may be too early to speculate, but will there also be a (for lack of a better term) IQueryable-like framework built for these new interfaces as well? One particular use case would be to assist in pre-processing events at the source, rather than in the chain of the receiving calls. For example, if you have a very 'chatty' event interface, using the Subscribe().Where(...) will receive all events through the pipeline and the client does the filtering. What I am wondering is if there will be something akin to IQueryableObservable, whereby these LINQ methods will be 'compiled' into some 'smart' Subscribe implementation in a source. I can imagine certain network server architectures that could use such a framework. Or how about an add-on to SQL Server (or any RDBMS for that matter) that would allow .NET code to receive new data notifications (triggers in code) and would need those notifications filtered server-side.

• Detecting network adapter changes on the iPhone

  - by theactiveactor

  Say that there are no WIFI networks currently available and my network-enabled app is connected over 3G. How can I detect if a user has roamed into a WIFI network? I would also like to detect the case when the user is connected over WIFI and suddenly received 3G signal. In other words, I would like to be asynchronously notified of network adapter changes. I tried using the SCNetworkReachability framework asynchronously but found that for some reason, I am not receiving Wifi-related events (i.e. adapter on/off) when connected over 3G.

• CodeIgniter: json_decode array issues

  - by thedp

  On my client side I'm sending an ajax request with jQuery in the following matter: $.post(script.php, { "var1":"something", "var2":"[1,2,3]" }, function(data) { }, "json"); On the server side, in the CodeIgniter's controller I'm receiving the values like so: $var1 = trim($this->input->post('var1')); $var2 = trim($this->input->post('var2')); My question is how do I convert the string in $var2 into a PHP array. I tried using json_decode($var2, true) but it returns a null since "[1,2,3]" is not a legal JSON string by itself. Also, if you believe there is a better way for me to read the values on the server-side please show me how. Thank you.

• Bitwise Shifting in C

  - by user313943

  I've recently decided to undertake an SMS project for sending and receiving SMS though a mobile. The data is sent in PDU format - I am required to change ASCII characters to 7 bit GSM alphabet characters. To do this I've come across several examples, such as http://www.dreamfabric.com/sms/hello.html This example shows Rightmost bits of the second septet, being inserted into the first septect, to create an octect. Bitwise shifts do not cause this to happen, as will insert to the left, and << to the right. As I understand it, I need some kind of bitwise rotate to create this - can anyone tell me how to move bits from the right handside and insert them on the left? Thanks,

• uh-oh windows mobile threading issues!

  - by violet313

  specifically WM6x, winCE5x Now my current understanding from trawling the msdn etal is that the IMAPIAdviseSink::OnNotify callback can be made from any old thread; from (ce)mapi or perhaps even from a third-party service provider. Under WM6x, i cannot seem to coax an in-thread response by invoking HrThisThreadAdviseSink, since while this function is declared in mapiutil.h, a definition appears not to exist (in cemapi.lib or wherever??) ~But i notice that all the OnNotify callbacks i get, derive from windows messages that i am receiving on my thread (=looks to me like an in-thread implementation in any case under cemapi)... So, can anyone confirm that this is infact always the case -or am i just getting lucky right now? ah, i should add that my advise source is IMAPISession::Advise (ActiveSync) erm i should also say that i might have cross-posted this on the msdn forum -but they're mostly numptys over there,,

• How to clear cache for previously installed InfoPath forms on a client computer?

  - by user313067

  Hi folks, We recently had a strange issue with an InfoPath 2007 form being opened from SharePoint 2007 and receiving the error message "the system cannot find the file specified". To be clear, this was not a form services enabled form. Anyway, after spending way too much time trying to figure out what was going on (nothing in the MOSS 2007 server log files), we determined that the user had previously installed an older version of the form (but with the same name) on their workstation using a no longer available msi file (meaning we could not uninstall it from the workstation). So I wanted to pass on a very simple solution for anyone who is unfortunate to run into this problem in the future (since I lost a great deal of hair over it): Fire up regedit, go to HKEY_LOCALMACHINE-Software-Microsoft-Office-InfoPath-SolutionsCatalog. Locate the key that has the previously installed form name, and delete it. This will cause InfoPath to stop trying to open the form locally (which is either old or doesn't exist) and force it to open your form from SharePoint. Hope this helps someone!

• Receving multiple multicast feeds on the same port - C, Linux

  - by Gigi

  I have an application that is receiving data from multiple multicast sources on the same port. I am able to receive the data. However, I am trying to account for statistics of each group (i.e. msgs received, bytes received) and all the data is getting mixed up. Does anyone know how to solved this problem? If I try to look at the sender's address, it is not the multicast address, but rather the IP of the sending machine. I am using the following socket options: struct ip_mreq mreq; mreq.imr_multiaddr.s_addr = inet_addr("224.1.2.3"); mreq.imr_interface.s_addr = INADDR_ANY; setsockopt(s, IPPROTO_IP, IP_ADD_MEMBERSHIP, &mreq, sizeof(mreq)); and also: setsockopt(s, SOL_SOCKET, SO_REUSEPORT, &reuse, sizeof(reuse)); I appreciate any help!!!
