  • Why isn't IE displaying this alert()?

    - by George Edison
    I have the following piece of code: // setup the AJAX request var pageRequest = false; if(window.XMLHttpRequest) pageRequest = new XMLHttpRequest(); else if(window.ActiveXObject) pageRequest = new ActiveXObject("Microsoft.XMLHTTP"); // callback pageRequest.onreadystatechange = function() { alert('pageRequest.readyState: ' + pageRequest.readyState + '\npageRequest.status: ' + pageRequest.status); } pageRequest.open('POST','ajax.php',true); // q_str contains something like 'data=value...' pageRequest.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); pageRequest.setRequestHeader("Content-length", q_str.length); pageRequest.setRequestHeader("Connection", "close"); pageRequest.send(q_str); This works fine in Chrome, but IE chokes on it, spitting out an "Unspecified error." and it points to the line with the alert() in it. Why can't it display the alert?

  • Is select() Ok to implemnet single socket read/write timeout ?

    - by chmike
    I have an application processing network communication with blocking calls. Each thread manages a single connection. I've added a timeout on the read and write operation by using select prior to read or write on the socket. Select is known to be inefficient when dealing with large number of sockets. But is it ok, in term of performance to use it with a single socket or are there more efficient methods to add timeout support on single sockets calls ? The benefit of select is to be portable.

  • Subsonic foreign key returning collection?

    - by Shaul
    I'm just writing my first "Hello World" program using Subsonic, for which I've thrown together a simple little Customer/Invoice/InvoiceItem/Product database. The connection was successfully made to the DB, and it generated all the right ActiveRecord classes. But for some reason, the Invoice class has a property called Customers, which returns a collection of Customer objects, even though the Invoice table has a CustomerID field which has a foreign key to the Customer table. I would have expected a Customer property returning a single Customer object. I must be doing something wrong - but what?

  • Grails Services / Transactions / RuntimeException / Testing

    - by Rob
    I'm testing come code in a service with transactional set to true , which talks to a customer supplied web service the main part of which looks like class BarcodeService { .. /// some stuff ... try{ cancelBarCodeResponse = cancelBarCode(cancelBarcodeRequest) } catch(myCommsException e) { throw new RuntimeException(e) } ... where myCommsException extends Exception .. I have a test which looks like // As no connection from my machine, it should fail .. shouldFailWithCause(RuntimeException){ barcodeServices.cancelBarcodeDetails() } The test fails cause it's catching a myCommsException rather than the RuntimeException i thought i'd converted it to .. Anyone care to point out what i'm doing wrong ? Also will the fact that it's not a RuntimeException mean any transaction related info done before my try/catch actually be written out rather than thrown away ?? Thanks

  • SQL Profiles showing high activity

    - by Wong Chi
    I am running my application locally -- ie. No external traffic and very low number of queries, fully under my control. I see tons of 'Audit Login' and 'Audit Logout' events. What are these and where are they actually stored (ie. Where is this audit log)? Are these a hint of a problem with connections, because I have only a simple connection string within my app and thought that connections would remain active throughout the operation of my app (ie. a single login at launch, and then a single logout when terminating).

  • MS SQL Server Dates Excel

    - by KillerSnail
    I have data this is linked from SQL Server into an excel document. The column format on the SQL Server is datetime2. When I get the data via an ODBC connection it comes across as a string? I tried using CAST(column AS DATE ) but that didn't work. I tried reformatting via CONVERT(VARCHAR(10), column, 103) as well but that didn't work. I tried retrieving the data via Microsoft query as well but that didn't work. At the moment I am using VBA code like: While (ActiveCell.Value <> "") ActiveCell.Value = DATEVALUE(ActiveCell.Value) ActiveCell.Offset(1,0).Activate Wend and looping through each column that needs this treatment but 100000 rows in multiple columns takes forever to loop through. Are there any alternatives?

  • Table Adaptor Error when trying update

    - by JasonMc92
    Hi, I have a rather perplexing issue. I am using VB.net and SQL for my project. I have a database, to which the connection works. I also have a data table and data adaptor, both of which I know work. I am trying to update something in the database, yet it isn't working. Assume everything listed is declared correctly. What am I doing wrong? teacher_control_table.Rows(0)("DATA_TeacherLockPasscode") = txtPasscode1.Text table_adaptor2.Update(teacher_control_table) That last line throws the following exception: InvalidOperationException was unhandled. update requires a valid UpdateCommand when passed DataRow collection with modified rows.

  • How to go through every record in sqllite db?

    - by Pavel
    Hi guys. I think it's kinda easy one but still I'm new to android programming so please have patience. I want to know how can I get the number of records (rows) in a specific table in my db. I need this so I can create a loop to go through every record and add each one of it to the specific Array and display it later on. This is the source: db.openDataBase(); // open connection with db Cursor c = db.getTitle(5); // loop here through db, right now I'm fetching only one record startManagingCursor(c); //adding areas to the list here Area o1 = new Area(); o1.setOrderName(c.getString(1) + c.getString(2)); m_areas.add(o1); db.close(); Does anyone can help me with this please? Thx in advance!

  • How can I get an error or a warning from a PreparedStatement?

    - by Geo
    I had an update like this: update table set col1=?,col2=?,col3=? where col4=?; and I filled it up like this: statement.setString(1,"some_value"); statement.setString(2,"some_value"); statement.setString(3,"some_value"); and I forgot to add a fourth value.I did a executeUpdate and of course nothing happened to the database. I spent about 1 hour debugging it, to see where it goes wrong. I then modified my code to print the SQLWarning object returned by the getWarnings method. It always returned null. I even modified the code to the buggy state it was, before I set the fourth parameter, and still no warning. Does anyone know how one can get an error/warning? If it matters, my Connection is set to autoCommit.

  • Resources access problem from JAR

    - by aeter
    I have the following directory structure of a project: Folder "project" in Eclipse: --folder "src" --folder "resources" ----trayicon2.png --folder "db" ----test.db --folder "bin" I'm accessing the image with: Image image = Toolkit.getDefaultToolkit().getImage("resources/trayicon2.png"); and from Eclipse that is not a problem. Then I generate an "executable jar file", and add the dirs, making a directory structure of: Folder "project" --folder "db" ----test.db --folder "resources" ----trayicon2.png --project.jar And now the image is no more accessible. Also, the database is no more accessible; while in Eclipse I used to access it with: Connection conn = DriverManager.getConnection("jdbc:sqlite:db/test.db"); How can I access the resources (images and db) after generating the jar file "project.jar"?

  • Is there a way to expose multiple WCF services through a single endpoint?

    - by mafutrct
    I currently offer a service with many methods via WCF. I'd like to refactor so the single service is split into multiple classes, each offering a different set of functionality. However, I'd prefer to still have a single connection to the client. Is this possible? I guess the answer is No, so how should I solve this issue? Is there a workaround? Or is my idea completely stupid and I should change the design of the application?

  • Does TCP actually define 'TCP server' and 'TCP clients'? [closed]

    - by mjn
    In the Wikipedia article, TCP communication is explained using the terms 'client' and 'server'. It also uses the word 'peers'. But TCP actually does not define "TCP clients" and "TCP servers" - In the RFC 675 document (SPECIFICATION OF INTERNET TRANSMISSION CONTROL PROGRAM), the word "client" never appears. The RFC explains that TCP is used to connect processes over ports (sockets), and that 'A pair of sockets form a CONNECTION which can be used to carry data in either direction [i.e. full duplex]. Calling the originating party the "client" seems to be common practice. But this client/server communication model is not always applicable to TCP communication. For example take peer-to-peer networks. Calling all processes which open a socket (and wait for incoming connections from peers) "TCP servers", sounds wrong to me. I would not call my uncle's telephone device a "Telephony server" if I dial his phone number and he picks up.

  • How to determine IP used by client connecting to INADDR_ANY listener socket in C

    - by codebox_rob
    I have a network server application written in C, the listener is bound using INADDR_ANY so it can accept connections via any of the IP addresses of the host on which it is installed. I need to determine which of the server's IP addresses the client used when establishing its connection - actually I just need to know whether they connected via the loopback address 127.0.0.1 or not. Partial code sample as follows (I can post the whole thing if it helps): static struct sockaddr_in serverAddress; serverAddress.sin_family = AF_INET; serverAddress.sin_addr.s_addr = INADDR_ANY; serverAddress.sin_port = htons(port); bind(listener, (struct sockaddr *) &serverAddress, sizeof(serverAddress)); listen(listener, CONNECTION_BACKLOG); SOCKET socketfd; static struct sockaddr_in clientAddress; ... socketfd = accept(listener, (struct sockaddr *) &clientAddress, &length);

  • SQLITE - INSERT does not return error but no data is inserted.

    - by Nick
    I am attempting to insert data into a local SQLITE database file from a C# application. The transaction does not throw any errors but the data is not inserted. The same insert statement works from within a query analyzer. Do I need to perform a commit? Is there a Commit method? Command's transaction property is null.. var command = new SQLiteCommand(insert.BuildInsert(tableName,keyValuePairs),Connection); command.ExecuteNonQuery();

  • How to use separat block caches for secure and unsecure shop access in Magento?

    - by Uwe Mesecke
    I use the Magento block cache for the top navigation block. The problem is the block has to generate some urls for files in the skin directory that cannot be put into css files as the file names depend on category model data. Now when I open magento using a secure connection (https://) the navigation block is fetched from the cache and is sent to the browser but with the http:// urls resulting in a warning in most browsers about unsecure elements on the page. I'd like the have separat caches for secure and unsecure connections. The navigation block extends the class Mage_Catalog_Block_Navigation and therefore has the following cache configuration: $this->addData(array( 'cache_lifetime' => false, 'cache_tags' => array(Mage_Catalog_Model_Category::CACHE_TAG, Mage_Core_Model_Store_Group::CACHE_TAG), ));

  • FTP - way to programatically determine time remaining or bytes transfered?

    - by ciaranarcher
    Hi all I want to make an FTP connection (ideally using Coldfusion 8, but Java is fine too) that will copy a file to a remote server. Crucially however, I want to know how many bytes have been transferred so I can give some feedback to the user. Is this possible, and if so what FTP API would you recommend as I understand the Sun implementation may be a bit lacking. Thanks in advance! PS: I could have another process/thread poll the file size on the destination machine via a web service call while the file is being transferred but it's not ideal. Getting it through FTP API would be the neatest solution.

  • Mysql maven jpa skeleton

    - by coubeatczech
    Hi, is there a skeleton for a project using mysql, some eclipse/top link with RESOURCE_LOCAL as connection type? Preferably using maven. I'm searching for it for hours and can't get running even the sipmlest exaple. So if you had it ready and running, please, post :-). Even something as simple as these two classes only. @Entity public class Message implements Serializable{ public Message() {} public Message(String s){ this.s = s; } @Id String s; public String getS(){ return s; } } public class App { static private EntityManagerFactory emf; static private EntityManager em; public static void main( String[] args ) { emf = Persistence.createEntityManagerFactory("persistence"); em = emf.createEntityManager(); Message m = new Message("abc"); em.persist(m); } }

  • 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.

  • Powershell - remote folder availability while counting files

    - by ziklop
    I´m trying to make a Powershell script that reports if there´s a file older than x minutes on remote folder. I make this: $strfolder = 'folder1 ..................' $pocet = (Get-ChildItem \\server1\edi1\folder1\*.* ) | where-object {($_.LastWriteTime -lt (Get-Date).AddDays(-0).AddHours(-0).AddMinutes(-20))} | Measure-Object if($pocet.count -eq 0){Write-Host $strfolder "OK" -foreground Green} else {Write-Host $strfolder "ERROR" -foreground Red} But there´s one huge problem. The folder is often unavailable for me bacause of the high load and I found out when there is no connection it doesn´t report an error but continues with zero in $pocet.count. It means it reports everything is ok when the folder is unavailable. I was thinking about using if(Test-Path..) but what about it became unavailable just after passing Test-Path? Does anyone has a solution please? Thank you in advance

Sometimes you need to do builds for live and testbeds in the same day ! Its really hard to change big project namespaces everytime you build. How can I just change the webconfig connection string and get it done? Thanks,
