  • WCF - (504) The server did not return a response for this request.

    - by Sanjay Sen
    I have a JSONP WCF service,using back end as MySql.It is working properly when i run it locally with visual studio. Now we have hosted it in Windows Server 2003. Now there is very strange problem occurring.. When I do a request with fiddler which does not require much processing internally, it gives me result 200 OK with desired output as response, But when I do a request which requires some internal data processing, it gives me 504 error(gateway time out error). I also looked at C:\WINDOWS\system32\LogFiles to see if it logs any error but it shows ok result in fiddler request which is as follows: Fields: date time s-sitename s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs(User-Agent) sc-status sc-substatus sc-win32-status 2010-04-07 10:08:06 W3SVC490896353 s-ip GET /InitialState.svc/GetInitialState reference=1&pageId=18 8080 - c-ip Fiddler 200 0 64 Can anyone please help me to resolve the problem ?? Or any ideas i can try to find out why it is happening ?? Any help will be appreciated...

  • ExtJS combo setting problem

    - by Hubidubi
    Hi I run into an interesting problem while was using combos in input form. My form contains combos that get data from json stores. It works fine when adding new record, but when the form is opened for editing an existing record, sometimes the id appears as selected not its value (eg: there's 5 instead of "apple"). I think it tries to set the value before it finishes loading the combo. Is there a way to solve this? I put the code down here that creates combos: function dictComboMaker( store, fieldLabel, hiddenName, name, allowBlank, myToolTipp ) { comboo = { xtype : 'combo', id: 'id-'+name, allowBlank: allowBlank, fieldLabel : fieldLabel, forceSelection : true, displayField : 'value', valueField : 'id', editable: false, name: name, hiddenName : hiddenName, minChars : 2, mode: 'remote', triggerAction : 'all', store : store }; function dictJsonMaker(url) { store = new Ext.data.JsonStore({ root : 'results', // 1 fields : [ 'id','value' ], url : url, autoLoad: true}); return store; } var comboKarStore = dictJsonMaker('/service/karok'); var comboKar= dictComboMaker(comboKarStore, 'Kar', 'karid', 'kar', false, ''); // then comboKar is added to the form Hubidubi

  • Attaching a List of Value [LOV] to an existing page item in APEX

    - by Sathya
    I'm pretty new to APEX ( well, just started using it ~an hour ago), and I'm stuck at a pretty basic level. I've created a simple form with all the required fields. I've created a simple LOV. I can't seem to figure out how to Attach the LOV to the existing item. I tried to attach the LOV by heading over to the item's property and selecting the LOV I created, but it just doesn't seem to attach. Is this a bug with APEX or am I doing something wrong ? I'm using APEX 4.0 EA 2 [ http://tryapexnow.com ]

  • LLBLGenProDataSource : cannot see updates values of newly inserted item from a FormView

    - by tbone
    After performing a FormView.InsertItem, I am unable to read the new values from the bound object within the LLBLGenProDataSource that the FormView is bound to. I have tracing turned on, I can see the insert happen, and the data does make it into the database, yet when I examine the contents of LLBLGenProDataSource.EntityCollection(0) (there is only one item in the collection) I do not see the values from the FormView.....yet, they are somehow being inserted into the database. Relevant code: <llblgenpro:LLBLGenProDataSource ID="llbDataSource" runat="server" MaxNumberOfItemsToReturn="1" DataContainerType="EntityCollection" EntityCollectionTypeName="Domain.CollectionClasses.MetricCollection, Domain" LivePersistence="True" ThrowExceptionOnIllegalFieldInput="true" /> Private Sub frmEdit_ItemCreated(ByVal sender As Object, ByVal e As System.EventArgs) Handles frmEdit.ItemCreated If Me.llbDataSource.EntityCollection.Count = 0 Then Me.frmEdit.ChangeMode(FormViewMode.Insert) Me.llbDataSource.EntityCollection.Add(New MetricEntity) Me.frmEdit.DataBind() Else LoadDropdowns() End If End Sub Private Sub cmdSave_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmdSave.Click If Me.frmEdit.CurrentMode = FormViewMode.Edit Then Me.frmEdit.UpdateItem(False) ElseIf Me.frmEdit.CurrentMode = FormViewMode.Insert Then Me.frmEdit.InsertItem(False) 'Me.llbDataSource.DataBind() 'NOPE!

  • In database table design, how does "Virtual Goods" affect table design -- should we create an instan

    - by Jian Lin
    When we design a database table for a DVD rental company, we actually have a movie, which is an abstract idea, and a physical DVD, so for each rental, we have a many-to-many table with fields such as: TransactionID UserID DvdID RentedDate RentalDuration AmountPaid but what about with virtual goods? For example, if we let a user rent a movie online for 3 days, we don't actually have a DVD, so we may have a table: TransactionID UserID MovieID RentedDate RentalDuration AmountPaid should we create a record for each instance of "virtual good"? For example, what if this virtual good (the movie) can be authorized to be watched on 3 devices (with 3 device IDs), then should we then create a virtual good record in the VirtualGoods table, each with a VirtualGoodID and then another table that has VirtualGoodID DeviceID to match up the movie with the DeviceIDs? We can also just use the TransactionID as the VirtualGoodID. Are there circumstances where we may want to create a record to record this "virtual good" in a VirtualGoods table?

  • Can an arbitrary email adress be used in workflow send email activity

    - by Greg McGuffey
    I'm wondering if there is any way to be able to include an arbitrary email address as the To:, From:, CC: or BCC: fields of a send email activity? It appears that they must be contacts in the CRM. I ask this because I have a requirement to cc a known group email (no actual user associated with the email...something like [email protected] it's not a queue at all). I'm concerned that if I create a CRM user for this email, that when I move to production, I'll have to change all the workflows using this email to point to the CRM entity on the production box (assuming GUID is saved with activity). If an arbitrary email isn't possible, any other suggestions? Thanks!

  • Is there an extensible SQL like query language that is safe for exposing via a public API?

    - by Lokkju
    I want to expose some spatial (and a few non-spatial) datasets via a public API. The backend store will either be PostgreSQL/PostGIS, sqlite/spatialite, or CouchDB/GeoCouch. My goal is to find a some, preferably standard, way to allow people to make complex spatial queries against the data. I would like it to be a simple GET based request. The idea is to allow safe SQL type queries, without allowing unsafe ones. I would rather modify something that is off the shelf than doing the entire thing myself. I specifically want to support requesting specific fields from a table; joining results; and spatial functions that are already implemented by the underlying datastore. Ideas anyone?

  • Quick question about PayPal IPN Security

    - by Alix Axel
    PayPal IPN sends a POST request with a variable number of fields to the notify URL, in order to confirm that the POST request is legit we need to resubmit the same request along with a additional cmd=_notify-validate field to PayPal, which then replies SUCCESS or FAILURE. My question is, why do we need to resend the request to PayPal? Wouldn't something like this work? if (preg_match('~^(?:.+[.])?paypal[.]com$~i', gethostbyaddr($_SERVER['REQUEST_ADDR'])) > 0) { // request came from PayPal, it's legit. } Iff we can trust the server to correctly resolve IPs, I assume we can trust PayPal POST requests, no?

  • How to remember checkbox input in PHP Forms

    - by Derek
    For usability purposes I like to set up my form fields this way: <?php $username = $_POST['username']; $message = $_POST['message']; ?> <input type="text" name="username" value="<?php echo $username; ?>" /> <textarea name="message"><?php echo $message; ?></textarea> This way if the user fails validation, the form input he entered previously will still be there and there would be no need to start from scratch. My problem is I can't seem to keep check boxes selected with the option that the user had chosen before (when the page refreshes after validation fails). How to do this?

  • Web Services: more frequent "small" calls, or less frequent "big" calls

    - by Klay
    In general, is it better to have a web application make lots of calls to a web service getting smaller chunks of data back, or to have the web app make fewer calls and get larger chunks of data? In particular, I'm building a Silverlight app that needs to get large amounts of data back from the server in response to a query created by a user. Each query could return anywhere from a few hundred records to a few thousand. Each record has around thirty fields of mostly decimal-type data. I've run into the situation before where the payload size of the response exceeded the maximum allowed by the service. I'm wondering whether it's better (more efficient for the server/client/web service) to cut this payload vertically--getting all values for a single field with each call--or horizontally--getting batches of complete records with each call. Or does it matter?

  • Displaying desired properties from search results with grails compass

    - by ombud
    Hi, I've been stumped with the problem of displaying a selected set of properties returned as a result via a Compass query in grails. I have 300 columns in my domain class and what I'd like to do is to return ONLY THOSE values I specify (around 10 - 15 properties/fields/columns). All the 300 columns have been indexed, btw. I know I can do this using Lucene by cycling through returned hits and selectively calling a=getField(column_name), et c. My qiuestion is, how do I do the same thing using thee Compass Grails plugin ? Any help will gratefully be appreciated. Thanks in anticipation, Ombud

  • Rails form submission

    - by Danny McClelland
    Hi Everyone, I have a simple form to enter details of a new case (kase), it's working well and clicking submit stores the information and takes the user to the show.html.erb page. However, I wanted to move part of the form to the sidebar - to make things a little easier to see and use for the user, however, when I moved the section to the sidebar - anything entered during either a creation or edit within those sidebar fields is ignored. Any idea how I keep the fields in the sidebar, but include them as before? <% content_for :header do -%> Cases <% end -%> <% form_for(@kase) do |f| %> <%= f.error_messages %> <!-- #START SIDEBAR --> <% content_for :sidebar do -%> <% if @kase.avatar.exists? then %> <%= image_tag @kase.avatar.url %> <% else %> <p style="font-size:smaller"> You can upload an icon for this case that will display here.

  • How to change values of ListView elements in Codebehind

    - by Viredae
    Hello, I'm trying to create a table with Listview and one of the fields I'm using is supposed to show a hyperlink to a more detailed view of the data shown, how I want to do that is by using FindControl on the ID of that item and then changing the value into a hyperlink of the detailed view page with a querystring attached, the problem is that I have no idea how to re-insert that data back into the listview field, which looks something like this: <ItemTemplate> <td> <asp:Label ID="ViewLinkLabel" runat="server" Text='[insert Link Here]' /> </td> </ItemTemplate> Please bear in mind that I'm still an amateur in ASP.net, and if any of this seems too convoluted when there's a much easier to do this that I don't know about. Thank you

  • Slow insert speed in Postgresql memory tablespace

    - by Prashant
    Hi, I have a requirement where I need to store the records at rate of 10,000 records/sec into a database (with indexing on a few fields). Number of columns in one record is 25. I am doing a batch insert of 100,000 records in one transaction block. To improve the insertion rate, I changed the tablespace from disk to RAM.With that I am able to achieve only 5,000 inserts per second. I have also done the following tuning in the postgres config: Indexes : no fsync : false logging : disabled Other information: - Tablespace : RAM - Number of columns in one row : 25 (mostly integers) - CPU : 4 core, 2.5 GHz - RAM : 48 GB I am wondering why a single insert query is taking around 0.2 msec on average when database is not writing anything on disk (as I am using RAM based tablespace). Is there something I am doing wrong? Help appreciated. Prashant

  • UpdateModel prefix - ASP.NET MVC

    - by Kristoffer Ahl
    I'm having trouble with TryUpdateModel(). My form fields are named with a prefix but I am using - as my separator and not the default dot. <input type="text" id="Record-Title" name="Record-Title" /> When I try to update the model it does not get updated. If i change the name attribute to Record.Title it works perfectly but that is not what I want to do. bool success = TryUpdateModel(record, "Record"); Is it possible to use a custom separator?

  • Rails date/time picker (hopefully jquery)

    - by user219222
    Looking for a date and datetime picker that will integrate fairly seamlessly with Rails. I'm sure some people must be using something similar. I have tried the unobtrusive date picker plugin but it breaks with the latest release of Rails. calendar date select plugin uses prototype which I have removed from my app and don't want to add back. active calendar plugin - broken with latest Rails and hacked to fix but doesn't fill out the text fields when a model is loaded. Thanks very much.

I has to search fields like these: Visual Basic Enterprise Edition Visual C++ Visual J++ My code is: Directory dir = Lucene.Net.Store.FSDirectory.GetDirectory("Index", false); IndexSearcher searcher = new Lucene.Net.Search.IndexSearcher( dir,true); Term term = new Term("nombreAnalizado", _que); PrefixQuery query = new PrefixQuery(term); TopDocs topDocs = searcher.Search(query, 10000); This code works well in this case: "Enterprise" will match "Visual Basic Enterprise Edition" But "Enterprise E" doesn´t match anything. I removed white spaces at indexing time and when the user is searching. Thanks.

  • How do You Get a Specific Value From a System.Data.DataTable Object?

    - by Giffyguy
    I'm a low-level algorithm programmer, and databases are not really my thing - so this'll be a n00b question if ever there was one. I'm running a simple SELECT query through our development team's DAO. The DAO returns a System.Data.DataTable object containing the results of the query. This is all working fine so far. The problem I have run into now: I need to pull a value out of one of the fields of the first row in the resulting DataTable - and I have no idea where to even start. Microsoft is so confusing about this! Arrrg! Any advice would be appreciated. I'm not providing any code samples, because I believe that context is unnecessary here. I'm assuming that all DataTable objects work the same way, no matter how you run your queries - and therefore any additional information would just make this more confusing for everyone.

  • A tool or framework extension or code snippet for logging the internal state of objects?

    - by George Mauer
    When spiking on how something works or when my unit test behave in an unpredictable manner I usually have to drop into debug mode. 99% of my time in debug mode is spent checking the values of fields on objects to verify its state. I already have log4net set up, it would seem that if I could easily add a line of code to log out the state of objects I could remove most of my need to start up the bulky debugger. The problem is of course that to expose object state implicitly you need to manually override each object's ToString() method. What I would like to be able to do is the ability to do logger.LogState(someObject) and have logged out the object state including at least a formatted list of all the private variables, references (to some arbitrary depth), and collections. Does anyone know a tool/framework/code snippet that can be used to generate a string of the internal state of any object? I could of course write one myself but its a non-trivial problem and I'd prefer something someone has put some thought into.

  • Auto refresh web page

    - by Epitaph
    I have a web page which allows the user to carry out various operations that in turn modify the database. Also, this web application needs to keep track of various fields in database that keep changing with time. Is refreshing the page every few seconds the best possible way to implement this? For example, if there is a long list on the page requiring scrolling, it is hard to view the list since the page keeps resetting due to the refresh. I know, there are ways to retain the position of the scroll. But, could I use something more efficient?
