  • How to count children from different lists? [jQuery]

    - by Filip Breckx
    Hi, I'm trying to count the number of child elements a certain category has. This is the situation: <ul id="select_cat"> <li id="_1">Category 1 (<span>#</span>)</li> <li id="_2">Category 2 (<span>#</span>)</li> </ul> <ul id="cat_1> <li>Link 1</li> <li>Link 2</li> <li>Link 3</li> </ul> <ul id="cat_2"> <li>Link 1</li> <li>Link 2</li> </ul> So I want to count the number of children a category has. In this example the first cardinal sign should be 3, and the second should be 2. How can I do this, using jQuery. Check an example (not jQuery) Thanks!

  • Creating controls in ASP with dynamic IDs

    - by mattdell
    Hi, I'm creating a chat widget that will be dropped into CommunityServer. The widget works great, but I just discovered that if I drop two of these widgets onto the same page, only one of them works! And I'm quite certain the reason is because the chat window is defined in ASP, and now there are two instances of the chat window, with the same ID, on the same page. I am doing this with straight ASP & Javascript (not by choice), so my chat window is defined as: <telerik:RadListBox ID="rlbMessages" runat="server" > (don't mind that it's a telerik control). So I was hoping I could do something like this: <telerik:RadListBox ID="<%= 'rlbMessages' + chatRoomID %>" runat="server" > But from what I've gathered, apparently you can't assign ID's this way? What is the alternative?

  • Stored Procedure Parameters Not Available After Declared

    - by SidC
    Hi All, Pasted below is a stored procedure written in SQL Server 2005. My intent is to call this sproc from my ASP.NEt web application through the use of a wizard control. I am new to SQL Server and especially to stored procedures. I'm unsure why my parameters are not available to the web application and not visible in SSMS treeview as a parameter under my sproc name. Can you help me correct the sproc below so that the parameters are correctly instantiated and available for use in my web application? Thanks, Sid Stored Procedure syntax: USE [Diel_inventory] GO /****** Object: StoredProcedure [dbo].[AddQuote] Script Date: 05/09/2010 00:31:10 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER procedure [dbo].[AddQuote] as Declare @CustID int, @CompanyName nvarchar(50), @Address nvarchar(50), @City nvarchar(50), @State nvarchar(2), @ZipCode nvarchar(5), @Phone nvarchar(12), @FAX nvarchar(12), @Email nvarchar(50), @ContactName nvarchar(50), @QuoteID int, @QuoteDate datetime, @NeedbyDate datetime, @QuoteAmt decimal, @ID int, @QuoteDetailPartID int, @PartNumber float, @Quantity int begin Insert into dbo.Customers (CompanyName, Address, City, State, ZipCode, OfficePhone, OfficeFAX, Email, PrimaryContactName) Values (@CompanyName, @Address, @City, @State, @ZipCode, @Phone, @FAX, @Email, @ContactName) set @CustID = scope_identity() Insert into dbo.Quotes (fkCustomerID,NeedbyDate,QuoteAmt) Values(@CustID,@NeedbyDate,@QuoteAmt) set @QuoteID = scope_identity() Insert into dbo.QuoteDetail (ID) values(@ID) set @ID=scope_identity() Insert into dbo.QuoteDetailParts (QuoteDetailPartID, QuoteDetailID, PartNumber, Quantity) values (@ID, @QuoteDetailPartID, @PartNumber, @Quantity) END

  • Would this prevent the row from being read during the transaction?

    - by acidzombie24
    I remember an example where reads in a transaction then writing back the data is not safe because another transaction may read/write to it in the time between. So i would like to check the date and prevent the row from being modified or read until my transaction is finish. Would this do the trick? and are there any sql variants that this will not work on? update tbl set id=id where date>expire_date and id=@id Note: dateexpire_date happens to be my condition. It could be anything. Would this prevent other transaction from reading the row until i commit or rollback?

  • nhibernate mapping: delete collection, insert new collection with old IDs

    - by npeBeg
    my issue lokks similar to this one: (link) but i have one-to-many association: <set name="Fields" cascade="all-delete-orphan" lazy="false" inverse="true"> <key column="[TEMPLATE_ID]"></key> <one-to-many class="MyNamespace.Field, MyLibrary"/> </set> (i also tried to use ) this mapping is for Template object. this one and the Field object has their ID generators set to identity. so when i call session.Update for the Template object it works fine, well, almost: if the Field object has an Id number, UPDATE sql request is called, if the Id is 0, the INSERT is performed. But if i delete a Field object from the collection it has no effect for the Database. I found that if i also call session.Delete for this Field object, everything will be ok, but due to client-server architecture i don't know what to delete. so i decided to delete all the collection elements from the DB and call session.Update with a new collection. and i've got an issue: nhibernate performs the UPDATE operation for the Field objects that has non-zero Id, but they are removed from DB! maybe i should use some other Id generator or smth.. what is the best way to make nhibernate perform "delete all"/"insert all" routine for the collection?

  • overwrite parameters passed by querystring

    - by opensas
    I have the following problem I have a web framework built with classic asp that saves the page state in hidden textboxes, and then issues a submit to itself. Before submitting, we have a javascript functions that saves the action in a hidden "action" input, and then performs the submit. The page loads the state from those hidden texts, reads the action issued, reads extra parameters, like the id of the record to edit, and then builds the page accordingly. I'd like to make a url link to automatically start the page with "edit" action on a "x" id. So I was thinking about building the following url, for example http://myapp/user?action=edit&id=23 the problem is that when the page auto-submits, que url string keeps the parameters. I'd like to achieve the following: when the user clicks on http://myapp/user?action=edit&id=23 my page should receive the posted values action=edit and id=23 but the url should be just http://myapp/user and both parameters should be kept in the hidden texts... (I wonder if I make myself clear...) thanks a lot saludos sas ps: I have a couple of ideas about how to solve it, but I'll post them as answers...

  • No item exist at http://<servername>....Item may have been deleted ......

    - by Prakash
    I have a data view webpart of some other list on my Dispform.aspx page. I have added edit and create new links in it. Create new item link is workin fine but when I m clicking on edit, its showing me error: No item exist at http:....listname/Dispform.aspx?ID=1&Source=http://...listname/Allitems.aspx. It may have been deleted or renamed by other user. I found this post related to it. http://social.msdn.microsoft.com/Forums/en-US/sharepointcustomization/thread/e368d7c7-8878-4f74-a62b-9ebad50c6b9a But now in my case the problem is I don't wanna customize Allitems.aspx, and what I have understood in the above post guys have suggested that to change the query string.I can only customize DispForm.aspx. Now the query string which is passing by default is ID=@ID from Allitems.aspx to DispForm.aspx...and I have to use this ID query string variable in my parameter if I m passing it on to the next page. Anyone knows how to fix this? Thanks in advance,

  • Does "delegate" mean a type or an object?

    - by Michal Czardybon
    Reading from MSDN: "A delegate is a type that references a method. Once a delegate is assigned a method, it behaves exactly like that method." Does then "delegate" mean a type or an object?! ...It cannot be both. It seems to me that the single word is used in two different meanings: a type containing a reference to a method of some specified signature, an object of that type, which can be actually called like a method. I would prefer a more precise vocabulary and use "delegate type" for the first case. I have been recently reading a lot about events and delegates and that ambiguity was making me confused many times. Some other uses of "delegate" word in MSDN in the first meaning: "Custom event delegates are needed only when an event generates event data" "A delegate declaration defines a class that is derived from the class System.Delegate" Some other uses of "delegate" word in MSDN in the second meaning: "specify a delegate that will be called upon the occurrence of some event" "Delegates are objects that refer to methods. They are sometimes described as type-safe function pointers" What do you think? Why did people from Microsoft introduced this ambiguity? Am I the only person to have conceptual problems with different notions being referenced with the same word.

  • PHP DELETE immediately after select

    - by teehoo
    I have a PHP server script that SELECTs some data from a MySQL database. As soon as I have the result from mysql_query and mysql_fetch_assoc stored in my own local variables, I want to delete the row I just selected. The problem with this approach is that it seems that PHP has done pass-by-reference to my local variables instead of pass-by-value, and my local variables become undefined after the delete command. Is there anyway to get around this? Here is my code: $query="SELECT id, peerID, name FROM names WHERE peer = $userID AND docID = '$docID' AND seqNo = $nid"; $result = mysql_query($query); if (!$result) self::logError("FAIL:1 getUsersNamesUpdate() query: ".$query."\n"); if (mysql_num_rows($result) == 0) return array(); $row = mysql_fetch_assoc($result); $result = array(); $result["id"] = $row["id"]; $result["peerID"] = $row["peerID"]; $result["name"] = $row["name"]; $query="DELETE FROM names WHERE id = $result[id];"; $result = mysql_query($query); if (!$result) self::logError("FAIL:2 getUsersNamesUpdate() query: ".$query."\n"); return $result;

  • Incorrect component when querying immediately after insert using NHibernate

    - by Am
    I have the following mapping for my table in MySql: <class name="Tag, namespace" table="tags" > <id name="id" type="Int32" unsaved-value="0"> <generator class="native"></generator> </id> <property name="name" type="String" not-null="true"></property> <component name="record_dates" class="DateMetaData, namespace" > <property name="created_at" type="DateTime" not-null="true"></property> <property name="updated_at" type="DateTime" not-null="true"></property> </component> </class> As you see the record_dates property is defined as a component field of type DateMetaDate. Both created_at and updated_at fields in 'tags' table are updated via triggers. Thus I can insert a new record like such: var newTag = new Tag() { name = "some string here" } Int32 id = (Int32)Session.Save(tag); Session.Flush(); ITag t = Session.Get<Tag>(id); ViewData["xxx"] = t.name; // -----> not null ViewData["xxx"] = t.record_dates.created_at; // -----> is null However when querying the same record back immediately after it was inserted the record_dates field ends up null even though in the table those fields have got values. Can any one please point out why the Session.Get ignores getting everything back from the table? is it because it caches the newly created record for which the records_dates is null? If so how can it be told to ignore the cached version?

  • Conditional Batch file renaming with mysql data

    - by Paul Stevens
    Hello, I wonder if anyone knows how could I rename multiple files, all of them originally named with same structure, and add some data extracted from a mysql DB according to specifics rules. For example I have 500 files named with this vars: ID NAME ADDRESS PHONE.wav = 1234567 PAULSIMON WESTDR122 9942213456.wav Now I need to rename files taking some data from the databases for each file, and append the data from a query appended to the filename. For example add the data resulting from a query Where some conditions match, and the data to build the query is taked from original file name, as ID or NAME. i other words, lets say that I want to build a query taking ID & NAME from file 1234567 PAULSIMON WESTDR123 9942213456.wav as WHERE statements to take another value as BirthDATE and add this to new filename, so final result should be: ID NAME ADDRESS PHONE BIRTHDATE.wav I will appreciate any help on this. I need this to be done on a LINUX server.

  • Lucene.Net: How can I add a date filter to my search results?

    - by rockinthesixstring
    I've got my searcher working really well, however it does tend to return results that are obsolete. My site is much like NerdDinner whereby events in the past become irrelevant. I'm currently indexing like this Public Function AddIndex(ByVal searchableEvent As [Event]) As Boolean Implements ILuceneService.AddIndex Dim writer As New IndexWriter(luceneDirectory, New StandardAnalyzer(), False) Dim doc As Document = New Document doc.Add(New Field("id", searchableEvent.ID, Field.Store.YES, Field.Index.UN_TOKENIZED)) doc.Add(New Field("fullText", FullTextBuilder(searchableEvent), Field.Store.YES, Field.Index.TOKENIZED)) doc.Add(New Field("user", If(searchableEvent.User.UserName = Nothing, "User" & searchableEvent.User.ID, searchableEvent.User.UserName), Field.Store.YES, Field.Index.TOKENIZED)) doc.Add(New Field("title", searchableEvent.Title, Field.Store.YES, Field.Index.TOKENIZED)) doc.Add(New Field("location", searchableEvent.Location.Name, Field.Store.YES, Field.Index.TOKENIZED)) doc.Add(New Field("date", searchableEvent.EventDate, Field.Store.YES, Field.Index.UN_TOKENIZED)) writer.AddDocument(doc) writer.Optimize() writer.Close() Return True End Function Notice how I have a "date" index that stores the event date. My search then looks like this ''# code omitted Dim reader As IndexReader = IndexReader.Open(luceneDirectory) Dim searcher As IndexSearcher = New IndexSearcher(reader) Dim parser As QueryParser = New QueryParser("fullText", New StandardAnalyzer()) Dim query As Query = parser.Parse(q.ToLower) ''# We're using 10,000 as the maximum number of results to return ''# because I have a feeling that we'll never reach that full amount ''# anyways.

  • ZF2 - How to use the Hydrator/exchangeArray() to populate a nested object

    - by Dominic Watson
    I've got an object with values that are stored in my database. My object also contains another object which is stored in the database using just the ID of it (foreign key). http://framework.zend.com/manual/2.0/en/modules/zend.stdlib.hydrator.html Before the Hydrator/exchangeArray functionality in ZF2 you would use a Mapper to grab everything you need to create the object. Now I'm trying to eliminate this extra layer by just using Hydration/exchangeArray to populate my objects but am a bit stuck on creating the nested object. Should my entity have the Inner object's table injected into it so I can create it if the ID of it is passed to my 'exchangeArray' ? Here are example entities as an example. // Village id, name, position, square_id // Map Square id, name, type Upon sending square_id to my Village's exchangeArray() function. It would get the mapTable and use hydrator to pull in the square using the ID I have. It doesn't seem right to be to have mapper instances inside my entity as I thought they should be disconnected from anything but it's own entity specific parameters and functionality?

  • How do I keep users from spoofing data through a form?

    - by Jonathan
    I have a site which has been running for some time now that uses a great deal of user input to build the site. Naturally there are dozens of forms on the site. When building the site, I often used hidden form fields to pass data back to the server so that I know which record to update. an example might be: <input type="hidden" name="id" value="132" /> <input type="text" name="total_price" value="15.02" /> When the form is submitted, these values get passed to the server and I update the records based on the data passed (i.e. the price of record 132 would get changed to 15.02). I recently found out that you can change the attributes and values via something as simple as firebug. So...I open firebug and change the id value to "155" and the price value to "0.00" and then submit the form. Viola! I view product number 155 on the site and it now says that it's $0.00. This concerns me. How can I know which record to update without either a query string (easily modified) or a hidden input element passing the id to the server? And if there's no better way (I've seen literally thousands of websites that pass the data this way), then how would I make it so that if a user changes these values, the data on the server side is not executed (or something similar to solve the issue)? I've thought about encrypting the id and then decrypting it on the other side, but that still doesn't protect me from someone changing it and just happening to get something that matches another id in the database. I've also thought about cookies, but I've heard that those can be manipulated as well. Any ideas? This seems like a HUGE security risk to me.

  • Javascript - remove part of cookie with a split('|') like array

    - by MgS
    I'm abit stuck. I'm using jQuery. I have a cookie which has the value such as : 1,something|2,somethingg|1,something We are treating it as [0] as id and [1] as name. I need to remove ONE where the id == '1' for example, this will leave the cookie like this: 1,something|2,somethingg How do I go about this, it will probally be in a loop, but not sure how to remove one of them. I have this so far: function removeItem(id){ var cookieName = 'myCookie'; var cookie = $.cookie(cookieName); if(cookie){ var cookie = cookie.split('|'); $(cookie).each(function(index){ var thisCookieData = this.split(','); if(thisCookieData[0] == id ){ } }); }

  • EventAggregator, is it thread-safe?

    - by pfaz
    Is this thread-safe? The EventAggregator in Prism is a very simple class with only one method. I was surprised when I noticed that there was no lock around the null check and creation of a new type to add to the private _events collection. If two threads called GetEvent simultaneously for the same type (before it exists in _events) it looks like this would result in two entries in the collection. /// <summary> /// Gets the single instance of the event managed by this EventAggregator. Multiple calls to this method with the same <typeparamref name="TEventType"/> returns the same event instance. /// </summary> /// <typeparam name="TEventType">The type of event to get. This must inherit from <see cref="EventBase"/>.</typeparam> /// <returns>A singleton instance of an event object of type <typeparamref name="TEventType"/>.</returns> public TEventType GetEvent<TEventType>() where TEventType : EventBase { TEventType eventInstance = _events.FirstOrDefault(evt => evt.GetType() == typeof(TEventType)) as TEventType; if (eventInstance == null) { eventInstance = Activator.CreateInstance<TEventType>(); _events.Add(eventInstance); } return eventInstance; }

  • Why oh why doesn't my asp.net treeview update?

    - by Brendan
    I'm using an ASP.net treeview on a page with a custom XmlDataSource. When the user clicks on a node of the tree, a detailsview pops up and edits a bunch of things about the underlying object. All this works properly, and the underlying object gets updated in my background object-management classes. Yay! However, my treeview just isn't updating the display. Either immediately (which i would like it to), or on full page re-load (which is the minimal useful level i need it to be at). Am i subclassing XmlDataSource poorly? I really don't know. Can anyone point me in a good direction? Thanks! The markup looks about like this (chaff removed): <data:DefinitionDataSource runat="server" ID="DefinitionTreeSource" RootDefinitionID="uri:1"></data:DefinitionDataSource> <asp:TreeView ID="TreeView" runat="server" DataSourceID="DefinitionTreeSource"> <DataBindings> <asp:TreeNodeBinding DataMember="definition" TextField="name" ValueField="id" /> </DataBindings> </asp:TreeView> <asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" DataKeyNames="Id" DataSourceID="DefinitionSource" DefaultMode="Edit"> <Fields> <asp:BoundField DataField="Name" HeaderText="Name" HeaderStyle-Wrap="false" SortExpression="Name" /> <asp:CommandField ShowCancelButton="False" ShowInsertButton="True" ShowEditButton="True" ButtonType="Button" /> </Fields> </asp:DetailsView> And the DefinitionTreeSource code looks like this: public class DefinitionDataSource : XmlDataSource { public string RootDefinitionID { get { if (ViewState["RootDefinitionID"] != null) return ViewState["RootDefinitionID"] as String; return null; } set { if (!Object.Equals(ViewState["RootDefinitionID"], value)) { ViewState["RootDefinitionID"] = value; DataBind(); } } } public DefinitionDataSource() { } public override void DataBind() { base.DataBind(); setData(); } private void setData() { String defXML = "<?xml version=\"1.0\" ?>"; Test.Management.TestManager.Definition root = Test.Management.TestManager.Definition.GetDefinitionById(RootDefinitionID); if (root != null) this.Data = defXML + root.ToXMLString(); else this.Data = defXML + "<definition id=\"null\" name=\"Set Root Node\" />"; } } }
