  • Windows-1251 file inside UTF-8 site?

    - by Spoonk
    Hello everyone Masters Of Web Delevopment :) I have a piece of PHP script that fetches last 10 played songs from my winamp. This script is inside file (lets call it "lastplayed.php") which is included in my site with php include function inside a "div". My site is on UTF-8 encoding. The problem is that some songs titles are in Windows-1251 encoding. And in my site they displays like "??????"... Is there any known way to tell to this div with included "lastplayed.php" in it, to be with windows-1251 encoding? Or any other suggestions? P.S: The file with fetching script a.k.a. "lastplayed.php", is converted to UTF-8. But if it is ANCII it's the same result. I try to put and meta tag with windows-1251 between head tag but nothing happens again. P.P.S: Script that fetches the Winamp's data (lastplayed.php): <?php /****** * You may use and/or modify this script as long as you: * 1. Keep my name & webpage mentioned * 2.

  • ASP.NET catching controls from html generated from the database

    - by Drahcir
    I have a set of websites that basically do the exact same thing in terms of functionality, the only thing that varies is the css and how the html is laid out. Is there a way to generate the html from a database (ie retreiving the html from a table) and then catching the controls (like buttons, textboxes etc) from the code behind? UPDATE: Here is an example of what I want to acheive: <html> <div id="generatedContent" runat="server"> <!-- the following content has been generated from the database on the page load event --> <div> This is a textbox <input id="tb1" runat="server" type="text" /> This is a button <input type="submit" id="btn1" runat="server" value="My Button" /> </div> </div> </html> This is the code behind var tb1 = new HtmlControls.HtmlInputText(); tb1 = FindControl("tb1"); var btn1 = new New HtmlControls.HtmlInputSubmit(); btn1 = FindControl("btn1"); Now obviously since the html has been generated from the database (ie after the page has already been initialised) the FindControl method will return null.

  • How do I setup Linq to SQL and WCF

    - by Jisaak
    So I'm venturing out into the world of Linq and WCF web services and I can't seem to make the magic happen. I have a VERY basic WCF web service going and I can get my old SqlConnection calls to work and return a DataSet. But I can't/don't know how to get the Linq to SQL queries to work. I'm guessing it might be a permissions problem since I need to connect to the SQL Database with a specific set of credentials but I don't know how I can test if that is the issue. I've tried using both of these connection strings and neither seem to give me a different result. <add name="GeoDataConnectionString" connectionString="Data Source=SQLSERVER;Initial Catalog=GeoData;Integrated Security=True" providerName="System.Data.SqlClient" /> <add name="GeoDataConnectionString" connectionString="Data Source=SQLSERVER;Initial Catalog=GeoData;User ID=domain\userName; Password=blahblah; Trusted_Connection=true" providerName="System.Data.SqlClient" /> Here is the function in my service that does the query and I have the interface add the [OperationContract] public string GetCity(int cityId) { GeoDataContext db = new GeoDataContext(); var city = from c in db.Cities where c.CITY_ID == 30429 select c.DESCRIPTION; return city.ToString(); } The GeoData.dbml only has one simple table in it with a list of city id's and city names. I have also changed the "Serialization Mode" on the DataContext to "Unidirectional" which from what I've read needs to be done for WCF. When I run the service I get this as the return: SELECT [t0].[DESCRIPTION] FROM [dbo].[Cities] AS [t0] WHERE [t0].[CITY_ID] = @p0 Dang, so as I'm writing this I realize that maybe my query is all messed up?

  • Update "Properties" model when adding a new record in CakePHP

    - by Paul Willy
    Hi, I'm writing an application in CakePHP that, for now, is to be used to make quotes for customers. So Quote is a model. I want to have a separate model/table for something like "Property," which may be used by other models. Each time a user gets to the "Add Quote" action, I basically want to pull a Property called "nextQuoteNumber" or something along those lines, and then automatically increment that property, even if the new Quote isn't saved. So I don't think just using an autoincrement for Quote's id is appropriate here - also, the "quote number" could be different from the row's id. I know this is simple enough to do, but I'm trying to figure out the "proper" CakePHP way of doing it! I'm thinking that I should have a method inside the Property model, say "getProperty($property_name)", which would pull the value to return, and also increment the value... but I'm not sure what the best way of doing that is, or how to invoke this method from the Quotes controller. What should I do? Thanks in advance!

  • Why setPreferredSize does not change the size of the button?

    - by Roman
    Here is the code: import javax.swing.*; import java.awt.event.*; import java.awt.*; public class TestGrid { public static void main(String[] args) { JFrame frame = new JFrame("Colored Trails"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel mainPanel = new JPanel(); mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.Y_AXIS)); JPanel panel = new JPanel(); panel.setLayout(new GridLayout(4, 9)); panel.setMaximumSize(new Dimension(9*30-20,4*30)); JButton btn; for (int i=1; i<=4; i++) { for (int j=1; j<=4; j++) { btn = new JButton(); btn.setPreferredSize(new Dimension(30, 30)); panel.add(btn); } btn = new JButton(); btn.setPreferredSize(new Dimension(30, 10)); panel.add(btn); for (int j=1; j<=4; j++) { btn = new JButton(); btn.setPreferredSize(new Dimension(30, 30)); panel.add(btn); } } mainPanel.add(panel); frame.add(mainPanel); frame.setSize(450,950); frame.setVisible(true); } } I suppose to have a table of buttons with 4 rows and 9 columns. And the middle column should be narrower that other columns. I tried Dimension(30, 10) and Dimension(30, 10) both have no effect on the width of the middle column. Why?

  • Best way to store and deliver files on a CMS

    - by Tio
    Hi all.. First of all, this isn't another question about storing images on DB vs file system. I'm already storing the images on the file system. I'm just struggling to find a better way to show them to all my users. I' currently using this system. I generate a random filename using md5(uniqueid()), the problem that I'm facing, is that the image is then presented with a link like this: <img src="/_Media/0027a0af636c57b75472b224d432c09c.jpg" /> As you can see this isn't the prettiest way to show a image ( or a file ), and the name doesn't say anything about the image. I've been working with a CMS system at work, that stores all uploaded files on a single table, to access that image it uses something like this: <img src="../getattachment/94173104-e03c-499b-b41c-b25ae05a8ee1/Menu-1/Escritorios.aspx?width=175&height=175" /> As you can see the path to the image, now has a meaning compared to the other one, the problem is that this put's a big strain in the DB, for example, in the last site I made, I have an area that has around 60 images, to show the 60 images, I would have to do at least 60 individual query's to the database, besides the other query's to retrieve the various content on the page. I think you understand my dilemma, has anyone gone trough this problem, that can give me some pointers on how to solve this? Thanks..

  • How to restrict text search to a certain subset of the database ?

    - by Nikhil Garg
    I have a large central database of around 1 million heavy records. In my app, for every user I would have a subset of rows from central table, which would be very small (probably 100 records each).When a particular user has logged in , I would want to search on this data set only. Example: Say I have a central database of all cars in the world. I have a user profile for General Motors(GM) , Ferrari etc. When GM is logged in I just want to search(a full text search and not fire a sql query) for those cars which are manufactured by GM. Also GM may launch/withdraw a model in which case central db would be updated & so would be rowset associated with GM. In case of acquisitions, db of certain profiles may change without launch/removal of new car. So central db wont change then , but rowsets may. Whats the best way to implement such a design ? These smaller row sets would need to be dynamic depending on user activities. We are on Rails 2.3.5 and use thinking_sphinx as the connector and Sphinx/MySQL for search and relational associations.

  • Would this method work to scale out SQL queries?

    - by David
    I have a database containing a single huge table. At the moment a query can take anything from 10 to 20 minutes and I need that to go down to 10 seconds. I have spent months trying different products like GridSQL. GridSQL works fine, but is using its own parser which does not have all the needed features. I have also optimized my database in various ways without getting the speedup I need. I have a theory on how one could scale out queries, meaning that I utilize several nodes to run a single query in parallel. The idea is to take an incoming SQL query and simply run it exactly like it is on all the nodes. When the results are returned to a coordinator node, the same query is run on the union of the resultsets. I realize that an aggregate function like average need to be rewritten into a count and sum to the nodes and that the coordinator divides the sum of the sums with the sum of the counts to get the average. What kinds of problems could not easily be solved using this model. I believe one issue would be the count distinct function. Edit: I am getting so many nice suggestions, but none have addressed the method.

  • UISplitView's DetailView not changing its content

    - by Knodel
    I have an iPad app with a UISplitView. In the Root View I have a two level UITableView (it takes its content from a plist). In the Detail View I have a UIWebView. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //Get the dictionary of the selected data source. NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row]; //Get the children of the present item. NSArray *Children = [dictionary objectForKey:@"Children"]; RootViewController *rvController = [[RootViewController alloc] init]; rvController.CurrentTitle = [dictionary objectForKey:@"Title"]; rvController.CurrentLevel = +1; //Push the new table view on the stack [self.navigationController pushViewController:rvController animated:YES]; rvController.tableDataSource = Children; NSString *name = [NSString stringWithFormat:@"%@.rtfd.zip", rvController.CurrentTitle ]; NSString* resourcePath = [[NSBundle mainBundle] resourcePath]; NSString* sourceFilePath = [resourcePath stringByAppendingPathComponent:name]; NSURL* url = [NSURL fileURLWithPath:sourceFilePath isDirectory:NO]; NSURLRequest* request = [NSURLRequest requestWithURL:url]; [detailViewController.webView loadRequest:request]; } That's how I want the UIWebView's content to be changed. If I name the .rtfd.zip file the same as a first level cell of the UITableView, it works, UIWebView's content changes. But this doesn't work with the second level UITableView. What am I doing wrong? Thanks in advance!

  • Best strategy for synching data in iPhone app

    - by iamj4de
    I am working on a regular iPhone app which pulls data from a server (XML, JSON, etc...), and I'm wondering what is the best way to implement synching data. Criteria are speed (less network data exchange), robustness (data recovery in case update fails), offline access and flexibility (adaptable when the structure of the database changes slightly, like a new column). I know it varies from app to app, but can you guys share some of your strategy/experience? For me, I'm thinking of something like this: 1) Store Last Modified Date in iPhone 2) Upon launching, send a message like getNewData.php?lastModifiedDate=... 3) Server will process and send back only modified data from last time. 4) This data is formatted as so: <+><data id="..."></data></+> // add this to SQLite/CoreData <-><data id="..."></data></-> // remove this <%><data id="..."><attribute>newValue</attribute></data></%> // new modified value I don't want to make <+, <-, <%... for each attribute as well, because it would be too complicated, so probably when receive a <% field, I would just remove the data with the specified id and then add it again (assuming id here is not some automatically auto-incremented field). 5) Once everything is downloaded and updated, I will update the Last Modified Date field. The main problem with this strategy is: If the network goes down when I am updating something = the Last Modified Date is not yet updated = next time I relaunch the app, I will have to go through the same thing again. Not to mention potential inconsistent data. If I use a temporary table for update and make the whole thing atomic, it would work, but then again, if the update is too long (lots of data change), the user has to wait a long time until new data is available. Should I use Last-Modified-Date for each of the data field and update data gradually?

  • How to set HTMLField's widget's height in Admin?

    - by Georgie Porgie
    I have a HTMLField in a model as it's the laziest way to utilize tinymce widget in Admin. But the problem is that the textarea field doesn't have "rows" property set. So the textarea doesn't have enough height comfortable enough for editing in Admin. Is there any way to set the height of HTMLField without defining a ModelAdmin class? Update: I solved the problem by using the following code: def create_mce_formfield(db_field): return db_field.formfield(widget = TinyMCE( attrs = {'cols': 80, 'rows': 30}, mce_attrs = { 'external_link_list_url': reverse('tinymce.views.flatpages_link_list'), 'plugin_preview_pageurl': reverse('tinymce-preview', args= ('tinymce',)), 'plugins': "safari,pagebreak,style,layer,table,save,advhr,advimage,advlink,emotions,iespell,inlinepopups,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template", 'theme_advanced_buttons1': "save,newdocument,|,bold,italic,underline,strikethrough,|,justifyleft,justifycenter,justifyright,justifyfull,styleselect,formatselect,fontselect,fontsizeselect", 'theme_advanced_buttons2': "cut,copy,paste,pastetext,pasteword,|,search,replace,|,bullist,numlist,|,outdent,indent,blockquote,|,undo,redo,|,link,unlink,anchor,image,cleanup,help,code,|,insertdate,inserttime,preview,|,forecolor,backcolor", 'theme_advanced_buttons3': "tablecontrols,|,hr,removeformat,visualaid,|,sub,sup,|,charmap,emotions,iespell,media,advhr,|,print,|,ltr,rtl,|,fullscreen", 'theme_advanced_buttons4': "insertlayer,moveforward,movebackward,absolute,|,styleprops,|,cite,abbr,acronym,del,ins,attribs,|,visualchars,nonbreaking,template,pagebreak", 'theme_advanced_toolbar_location': "top", 'theme_advanced_toolbar_align': "left", 'theme_advanced_statusbar_location': "bottom", 'theme_advanced_resizing': True, 'extended_valid_elements': "iframe[src|title|width|height|allowfullscreen|frameborder|webkitAllowFullScreen|mozallowfullscreen|allowFullScreen]", }, )) class TinyMCEFlatPageAdmin(FlatPageAdmin): def formfield_for_dbfield(self, db_field, **kwargs): if db_field.name == 'content': return create_mce_formfield(db_field) return super(TinyMCEFlatPageAdmin, self).formfield_for_dbfield(db_field, **kwargs)

  • PDO prepare silently fails

    - by Wabbitseason
    I'm experimenting with PHP's session_set_save_handler and I'd like to use a PDO connection to store session data. I have this function as a callback for write actions: function _write($id, $data) { logger('_WRITE ' . $id . ' ' . $data); try { $access = time(); $sql = 'REPLACE INTO sessions SET id=:id, access=:access, data=:data'; logger('This is the last line in this function that appears in the log.'); $stmt = $GLOBALS['db']->prepare($sql); logger('This never gets logged! :('); $stmt->bindParam(':id', $id, PDO::PARAM_STR); $stmt->bindParam(':access', $access, PDO::PARAM_INT); $stmt->bindParam(':data', $data, PDO::PARAM_STR); $stmt->execute(); $stmt->closeCursor(); return true; } catch (PDOException $e) { logger('This is never executed.'); logger($e->getTraceAsString()); } } The first two log messages always show up, but the third one right after $stmt = $GLOBALS['db']->prepare($sql) never makes it to the log file and there's no trace of an exception either. The sessions db table remains empty. The log message from the _close callback is always present. Here's how I connect to the database: $db = new PDO('mysql:host=' . DBHOST . ';dbname=' . DBNAME, DBUSER, DBPASS); $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); I have PHP 5.2.10. I tried to simply run $GLOBALS['db']->exec($sql) with a "manually prepared" $sql content, but it still failed silently. The query itself is all right I was able to execute it via the db console.

  • Preserve whitespace and formatting for text returned from $.get jquery call

    - by desigeek
    I have a jquery $.get() call in my app that requests an entire web page. In the callback function, I access a div in the returned page, get its data and show it on my page. The problem is that the text I get from the div does not preserve the source formatting. If the div in the requested page had say an ordered list, then when i get that text and display on my page, it shows up as a paragraph with items inline instead of being shown as a list. I do not know whether the problem is how $.get() is getting the data or in my displaying of the data. //get the page $.get($(this).attr('href'), function(data){ callbackFunc(data,myLink); }, "html"); function callbackFunc(responseText, customData){ //response has bg color of #DFDFDF var td = $("td[bgcolor='#DFDFDF']", responseText); //text to show is in div of that td var forumText = $('div', td).text(); //append new row with request data below the current row in my table var currentRow = $(customData).parent('td').parent('tr'); var toAppend = "<tr><td class='myTd' colspan='3'>" + forumText + "</td></tr>"; $(currentRow).after(toAppend); } The response data shows up like ABC in the new row I add to my div while the source page div had A B C I should add that this script is part of an extension for Google Chrome so that is my only browser that I have tested on

  • How to make active services highly available?

    - by Jader Dias
    I know that with Network Load Balancing and Failover Clusteringwe can make passive services highly available. But what about active apps? Example: One of my apps retrieves some content from a external resource in a fixed interval. I have imagined the following scenarios: Run it in a single machine. Problem: if this instance falls, the content won't be retrieved Run it in each machine of the cluster. Problem: the content will be retrieved multiple times Have it in each machine of the cluster, but run it only in one of them. Each instance will have to check some sort of common resource to decide whether it its turn to do the task or not. When I was thinking about the solution #3 I have wondered what should be the common resource. I have thought of creating a table in the database, where we could use it to get a global lock. Is this the best solution? How does people usually do this? By the way it's a C# .NET WCF app running on Windows Server 2008

  • Avoiding secondary selects or joins with Hibernate Criteria or HQL query

    - by Ben Benson
    I am having trouble optimizing Hibernate queries to avoid performing joins or secondary selects. When a Hibernate query is performed (criteria or hql), such as the following: return getSession().createQuery(("from GiftCard as card where card.recipientNotificationRequested=1").list(); ... and the where clause examines properties that do not require any joins with other tables... but Hibernate still performs a full join with other tables (or secondary selects depending on how I set the fetchMode). The object in question (GiftCard) has a couple ManyToOne associations that I would prefer to be lazily loaded in this case (but not necessarily all cases). I want a solution that I can control what is lazily loaded when I perform the query. Here's what the GiftCard Entity looks like: @Entity @Table(name = "giftCards") public class GiftCard implements Serializable { private static final long serialVersionUID = 1L; private String id_; private User buyer_; private boolean isRecipientNotificationRequested_; @Id public String getId() { return this.id_; } public void setId(String id) { this.id_ = id; } @ManyToOne @JoinColumn(name = "buyerUserId") @NotFound(action = NotFoundAction.IGNORE) public User getBuyer() { return this.buyer_; } public void setBuyer(User buyer) { this.buyer_ = buyer; } @Column(name="isRecipientNotificationRequested", nullable=false, columnDefinition="tinyint") public boolean isRecipientNotificationRequested() { return this.isRecipientNotificationRequested_; } public void setRecipientNotificationRequested(boolean isRecipientNotificationRequested) { this.isRecipientNotificationRequested_ = isRecipientNotificationRequested; } }

  • oracle plsql select pivot without dynamic sql to group by

    - by kayhan yüksel
    To whom it may respond to, We would like to use SELECT function with PIVOT option at a 11g r2 Oracle DBMS. Our query is like : "select * from (SELECT o.ship_to_customer_no, ol.item_no,ol.amount FROM t_order o, t_order_line ol WHERE o.NO = ol.order_no and ol.item_no in (select distinct(item_no) from t_order_line)) pivot --xml ( SUM(amount) FOR item_no IN ( select distinct(item_no) as item_no_ from t_order_line));" As can be seen, XML is commented out, if run as PIVOT XML it gives the correct output in XML format, but we are required to get the data as unformatted pivot data, but this sentence throws error : ORA-00936: missing expression Any resolutions or ideas would be welcomed, Best Regards -------------if we can get the result of this to sys_refcursor using execute immediate it will be solved ------------------------ the procedure : PROCEDURE pr_test2 (deneme OUT sys_refcursor) IS v_sql NVARCHAR2 (4000) := ''; TYPE v_items IS TABLE OF NVARCHAR2 (30); v_pivot_items NVARCHAR2 (4000) := ''; BEGIN FOR i IN (SELECT DISTINCT (item_no) AS items FROM t_order_line) LOOP v_pivot_items := ',''' || i.items || '''' || v_pivot_items; END LOOP; v_pivot_items := LTRIM (v_pivot_items, ','); v_sql := 'begin select * from (SELECT o.ship_to_customer_no, ol.item_no,ol.amount FROM t_order o, t_order_line ol WHERE o.NO = ol.order_no and OL.ITEM_NO in (select distinct(item_no) from t_order_line)) pivot --xml ( SUM(amount) FOR item_no IN (' || v_pivot_items || '));end;'; open DENEME for select v_sql from dual; Kayhan YÜKSEL

  • TSQL - make a literal float value

    - by David B
    I understand the host of issues in comparing floats, and lament their use in this case - but I'm not the table author and have only a small hurdle to climb... Someone has decided to use floats as you'd expect GUIDs to be used. I need to retrieve all the records with a specific float value. sp_help MyTable -- Column_name Type Computed Length Prec -- RandomGrouping float no 8 53 Here's my naive attempt: --yields no results SELECT RandomGrouping FROM MyTable WHERE RandomGrouping = 0.867153569942739 And here's an approximately working attempt: --yields 2 records SELECT RandomGrouping FROM MyTable WHERE RandomGrouping BETWEEN 0.867153569942739 - 0.00000001 AND 0.867153569942739 + 0.00000001 -- 0.867153569942739 -- 0.867153569942739 In my naive attempt, is that literal a floating point literal? Or is it really a decimal literal that gets converted later? If my literal is not a floating point literal, what is the syntax for making a floating point literal? EDIT: Another possibility has occurred to me... it may be that a more precise number than is displayed is stored in this column. It may be impossible to create a literal that represents this number. I will accept answers that demonstrate that this is the case. EDIT: response to DVK. TSQL is MSSQLServer's dialect of SQL. This script works, and so equality can be performed deterministically between float types: DECLARE @X float SELECT top 1 @X = RandomGrouping FROM MyTable WHERE RandomGrouping BETWEEN 0.839110948199148 - 0.000000000001 AND 0.839110948199148 + 0.000000000001 --yields two records SELECT * FROM MyTable WHERE RandomGrouping = @X I said "approximately" because that method tests for a range. With that method I could get values that are not equal to my intended value. The linked article doesn't apply because I'm not (intentionally) trying to straddle the world boundaries between decimal and float. I'm trying to work with only floats. This isn't about the non-convertibility of decimals to floats.

  • How to bundle extension methods requiring configuration in a library

    - by Greg
    Hi, I would like to develop a library that I can re-use to add various methods involved in navigating/searching through a graph (nodes/relationships, or if you like vertexs/edges). The generic requirements would be: There are existing classes in the main project that already implement the equivalent of the graph class (which contains the lists of nodes / relationships), node class and relationship class (which links nodes together) - the main project likely already has persistence mechanisms for the info (e.g. these classes might be built using Entity Framework for persistance) Methods would need to be added to each of these 3 classes: (a) graph class - methods like "search all nodes", (b) node class - methods such as "find all children to depth i", c) relationship class - methods like "return relationship type", "get parent node", "get child node". I assume there would be a need to inform the library with the extending methods the class names for the graph/node/relationships table (as different project might use different names). To some extent it would need to be like how a generics collection works (where you pass the classes to the collection so it knows what they are). Need to be a way to inform the library of which node property to use for equality checks perhaps (e.g. if it were a graph of webpages the equality field to use might be the URI path) I'm assuming that using abstract base classes wouldn't really work as this would tie usage down to have to use the same persistence approach, and same class names etc. Whereas really I want to be able to, for a project that has "graph-like" characteristics, the ability to add graph searching/walking methods to it.

  • ConcurrentLinkedQueue$Node remains in heap after remove()

    - by action8
    I have a multithreaded app writing and reading a ConcurrentLinkedQueue, which is conceptually used to back entries in a list/table. I originally used a ConcurrentHashMap for this, which worked well. A new requirement required tracking the order entries came in, so they could be removed in oldest first order, depending on some conditions. ConcurrentLinkedQueue appeared to be a good choice, and functionally it works well. A configurable amount of entries are held in memory, and when a new entry is offered when the limit is reached, the queue is searched in oldest-first order for one that can be removed. Certain entries are not to be removed by the system and wait for client interaction. What appears to be happening is I have an entry at the front of the queue that occurred, say 100K entries ago. The queue appears to have the limited number of configured entries (size() == 100), but when profiling, I found that there were ~100K ConcurrentLinkedQueue$Node objects in memory. This appears to be by design, just glancing at the source for ConcurrentLinkedQueue, a remove merely removes the reference to the object being stored but leaves the linked list in place for iteration. Finally my question: Is there a "better" lazy way to handle a collection of this nature? I love the speed of the ConcurrentLinkedQueue, I just cant afford the unbounded leak that appears to be possible in this case. If not, it seems like I'd have to create a second structure to track order and may have the same issues, plus a synchronization concern.

  • Ideas on frameworks in .NET that can be used for job processing and notifications

    - by Rajat Mehta
    Scenario: We have one instance of WCF windows service which exposes contracts like: AddNewJob(Job job), GetJobs(JobQuery query) etc. This service is consumed by 70-100 instances of client which is Windows Form based .NET app. Typically the service has 50-100 inward calls/minute to add or query jobs that are stored in a table on Sql Server. The same service is also responsible for processing these jobs in real time. It queries database every 5 seconds picks up the queued jobs and starts processing them. A job has 6 states. Queued, Pre-processing, Processing, Post-processing, Completed, Failed, Locked. Another responsibility on this service is to update all clients on every state change of every job. This means almost 200+ callbacks to clients per second. Question: This whole implementation is done using WCF Duplex bindings and works perfectly fine on small number of parallel jobs. Problem arises when we scale it up to 1000 jobs at a time. The notifications don't work as expected, it leads to memory overflow etc. Is there any standard framework that can provide a clean infrastructure for handling this scenario?? Apologies for the long explanation!

  • Rails - CSV export: prompt for file download

    - by Pierre
    Hello, I want to give my users the ability to export a table to CSV. So in my controller, I've added on top of the file: respond_to :html, :js, :csv I'm also setting the headers if the requested format is csv: if params[:format] == 'csv' generate_csv_headers("negotiations-#{Time.now.strftime("%Y%m%d")}") end Code for generate_csv_headers(in application_controller) is: def generate_csv_headers(filename) headers.merge!({ 'Cache-Control' => 'must-revalidate, post-check=0, pre-check=0', 'Content-Type' => 'text/csv', 'Content-Disposition' => "attachment; filename=\"#{filename}\"", 'Content-Transfer-Encoding' => 'binary' }) end I've also created a view named index.csv.erb to generate my file: <%- headers = ["Id", "Name"] -%> <%= CSV.generate_line headers %> <%- @negotiations.each do |n| -%> <%- row = [ n.id, n.name ] -%> <%= CSV.generate_line row %> <%- end -%> I don't have any error, but it simply displays the content of the CSV file, while I'd expect a prompt from the browser to download the file. I've read a lot, but could not find anything that'd work. Do you have an idea? thanks, p.

  • Why is the ASP.NET Repeater.Items collection empty, when controls are on the screen?

    - by Ryan
    I have an ASP page with the following repeater: <asp:Repeater runat="server" ID="RegionRepeater" DataSourceID="SqlDataSourceRegions" EnableViewState="true"> <ItemTemplate> <tr> <td valign="top"> <b><%#Eval("description")%></b> <asp:HiddenField runat="server" ID="RegionID" Value='<%#Eval("region_id")%>'/> </td> <td> <asp:FileUpload ID="FileUpload" runat="server" Width="368px" /> </td> </tr> </ItemTemplate> </asp:Repeater> (The repeater is inside a Wizard, inside a content pane). The code behind is connected to the protected void Wizard1_NextButtonClick(object sender, WizardNavigationEventArgs e) event. There are two items on the screen (two rows inside the table). However, when the code tries to read those items, the Items collection is empty! foreach(RepeaterItem region in RegionRepeater.Items) { // Never runs - the RegionRepeater.Items.Count = 0 FileUpload fileUpload = (FileUpload) region.FindControl("FileUpload"); String regionID = ((HiddenField)region.FindControl("RegionID")).Value; ... Why is the collection empty, when there are controls drawn on the screen? Thanks a lot for any help; this is starting to drive me nuts. (BTW: I tried adding/removing the EnableViewState="true" tag)

  • NHibernate slow mapping

    - by Rob A
    My question is what can I do to determine the cause of the slowness, or what can I do to speed it up without knowing the exact cause. I am running a simple query and it appears that the mapping back to the entities is taking taking forever. The result set is 350, which is not much data in my opinion. IRepository repo = ObjectFactory.GetInstance<IRepository>(); var q = repo.Query<Order>(item => item.Ordereddate > DateTime.Now.AddDays(-40)); foreach (var order in q) { Console.WriteLine(order.TransactionNumber); } The profiler is telling me it is executing the query 7ms / 35257ms, I am assuming that the former is the actual response from the db and the latter is the time it takes NH to do it's magic. 35 seconds is too long. This is a simple mapping, one table, nested components, using fluent interface to do mappings. I just start up a simple console app and run the one query, the slowness is measured after the SessionFactory is initialized, there should only be one session, and I am not using a transaction. Thanks
