Using a UIPickerView to make a CoreData Relationship

- by DVG

Okay, so I have a fairly simple application set up. I have two different CoreData Entities, Games and Platforms, each have one attribute: name, and they have a one-to-many relationship between them. Platforms are populated on the first launch of the application, and will never change as a result of user input. I'm working on my Add view to let the user add new games to their personal database, and each game should select from a platform. The add view itself is a grouped table view with static custom cells. Tapping the platform cell should advance the user to another view to select the platform. My thought is that UIPickerView seems like a logical choice for the control, since the Platform list is static, but I'm not sure how to use it with CoreData. Even if I construct a fetch request to get the Platform objects and extract the strings out, how do I go about linking the new Game object to the original Platform object?

WCF via SSL connectivity problems

- by Brett Widmeier

Hello, I am hosting a WCF service from inside a Windows service using WAS. When I set the service to listen on 127.0.0.1, I have connectivity from my local machine as well as from my network. However, when I set it to listen on my outbound interface port 443, I can no longer even see the wsdl by connecting with a browser. Strangely, I can connect to the service by using telnet. The cert I am using was generated for my interface by a CA, and I have successfully used this exact cert with this service before. When checking the application log, I see that the service starts without error and is listening on the correct interface. From this information, it seems to me that the config file is in a valid state, but somehow misconfigured for what I want. I have, however, previously deployed this same setup on other sites using this config file. In case it is helpful, below is my config file. Any thoughts?  <appSettings/> <connectionStrings/> <system.serviceModel>  <bindings> <basicHttpBinding> <binding name="basicHttps"> <security mode="Transport"> <transport clientCredentialType="None"/> <message /> </security> </binding> </basicHttpBinding> </bindings> <services> <service behaviorConfiguration="ServiceBehavior" name="<fully qualified name of service>"> <endpoint address="" binding="basicHttpBinding" name="OrdersSoap" contract="<fully qualified name of contract>" bindingNamespace="http://emr.orders.com/WebServices" bindingConfiguration="basicHttps" /> <endpoint binding="mexHttpsBinding" address="mex" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="https://<external IP>/<name of service>>/" /> </baseAddresses> </host> </service> </services> <behaviors> <serviceBehaviors> <behavior name="ServiceBehavior"> <serviceMetadata httpsGetEnabled="False"/> <serviceDebug includeExceptionDetailInFaults="True" /> <dataContractSerializer maxItemsInObjectGraph="2147483646"/> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel>

Inserting Large volume of data in SQL Server 2005

- by Manjoor

We have a application (written in c#) to store live stock market price in the database (SQL Server 2005). It insert about 1 Million record in a single day. Now we are adding some more segment of market into it and the no of records would be double (2 Millions/day). Currently the average record insertion per second is about 50, maximum is 450 and minimum is 0. To check certain conditions i have used service broker (asynchronous trigger) on my price table. It is running fine at this time(about 35% CPU utilization). Now i am planning to create a in memory dataset of current stock price. we would like to do some simple calculations. I want to know different views of members on this. Please provide your way of dealing with such situation.

CrossPage PostBack in series of web pages

- by Vishnu Reddy

I had a requirement to pass data between pages in my application. I have a Page A where user will input some data and on submit User will be redirected to Page B where again user will enter some more data and on submitting user will be show a confirmation in Page C after doing some calculations and data saving. Following is the idea I was trying to use: PageA.aspx: <form id="frmPageA" runat="server"> <p>Name: <asp:TextBox ID="txtName" runat="server"></asp:TextBox></p> <p>Age: <asp:TextBox ID="txtAge" runat="server"></asp:TextBox></p> <p><asp:Button ID="btnPostToPageB" runat="server" Text="Post To PageB" PostBackUrl="~/PageB.aspx" /></p> </form> In Page A Codebehind file I am creating following public properties of the inputs to access in Page B: public string Name { get { return txtName.Text.ToString(); } } public int Age { get { return Convert.ToInt32(txtAge.Text); } } In PageB.aspx: using previouspage directive to access page A public properties <%@ PreviousPageType VirtualPath="~/PageA.aspx" % <form id="frmPageB" runat="server"> <asp:HiddenField ID="hfName" runat="server" /> <asp:HiddenField ID="hfAge" runat="server" /> <p><asp:RadioButtonList ID="rblGender" runat="server" TextAlign="Right" RepeatDirection="Horizontal"> <asp:ListItem Value="Female">Female</asp:ListItem> <asp:ListItem Value="Male">Male</asp:ListItem> </asp:RadioButtonList></p> <p><asp:Button ID="btnPostToPageC" runat="server" Text="Post To PageC" PostBackUrl="~/PageC.aspx" /></p> </form> In Page B Codebehind file I am creating following public properties for the inputs to access in Page C: public RadioButtonList Gender { get { return rblGender; } } public string Name { get { return _name; } } public int Age { get { return _age; } } //checking if data is posted from Page A otherwise redirecting User to Page A protected void Page_Load(object sender, EventArgs e) { if (PreviousPage != null && PreviousPage.IsCrossPagePostBack && PreviousPage.IsValid) { hfName.Value = PreviousPage.Name; hfAge.Value = PreviousPage.Age.ToString(); } else Response.Redirect("PageA.aspx"); }` in PageC.aspx: using previouspage directive to access page A public properties <%@ PreviousPageType VirtualPath="~/PageB.aspx" % <form id="frmPageC" runat="server"> <p>Name: <asp:Label ID="lblName" runat="server"></asp:Label></p> <p>Age: <asp:Label ID="lblAge" runat="server"></asp:Label></p> <p>Gender: <asp:Label ID="lblGender" runat="server"></asp:Label></p> <p><asp:Button ID="btnBack" runat="server" Text="Back" PostBackUrl="~/PageA.aspx" /></p> </form> Page C code behind file: if (PreviousPage != null && PreviousPage.IsCrossPagePostBack && PreviousPage.IsValid) { lblName.Text = PreviousPage.Name.ToString(); lblAge.Text = PreviousPage.Age.ToString(); lblGender.Text = PreviousPage.Gender.SelectedValue.ToString(); } else Response.Redirect("PageA.aspx");

database design question

- by Leonardo

Hi all, I am building a database as a simple exercise, it could be hosted on any database server, so I am trying to keep things as much standard as possible. Basically what I would like to do is a 'code' table that get referenced by other entities. I explain: xcode id code r role p property code r admin r staff p title .... then I would like to have some view like: role (select * from code where xcode='r') r admin r staff property (select * from code where xcode='p') p title then, suppose we have an entity myentity id - 1 role - admin (foreign key to role) title - title (foreign key to property) Obviously I cannot create foreign key to a view, but this is to tell the idea I have in mind. How can I reflect such behaviour using whenever possible, standard sql syntax, then as a second option, database additional features like trigger ecc... ? Because if I tell that role and title in myentity are foreign key to 'code', instead of the views, nothing would stop me to insert a role in title field. thanks Leonardo

ASP.NET MVC: Accessing ModelMetadata for items in a collection

- by DanM

I'm trying to write an auto-scaffolder for Index views. I'd like to be able to pass in a collection of models or view-models (e.g., IEnumerable<MyViewModel>) and get back an HTML table that uses the DisplayName attribute for the headings (th elements) and Html.Display(propertyName) for the cells (td elements). Each row should correspond to one item in the collection. When I'm only displaying a single record, as in a Details view, I use ViewData.ModelMetadata.Properties to obtain the list of properties for a given model. But what happens when the model I pass to the view is a collection of model or view-model objects and not a model or view-model itself? How do I obtain the ModelMetadata for a particular item in a collection?

Setting column length of a Long value with JPA annotations

- by Gearóid

Hi, I'm performing a little database optimisation at the moment and would like to set the column lengths in my table through JPA. So far I have no problem setting the String (varchar) lengths using JPA as follows: @Column(unique=true, nullable=false, length=99) public String getEmail() { return email; } However, when I want to do the same for a column which is of type Long (bigint), it doesn't work. For example, if I write: @Id @Column(length=7) @GeneratedValue(strategy = GenerationType.AUTO) public Long getId() { return id; } The column size is still set as the default of 20. Are we able to set these lengths in JPA or am I barking up the wrong tree? Thanks, Gearoid.

How To Aggregate API Data?

- by Mindblip

Hi, I have a system that connects to 2 popular APIs. I need to aggregate the data from each into a unified result that can then be paginated. The scope of the project means that the system could end up supporting 10's of APIs. Each API imposes a max limit of 50 results per request. What is the best way of aggregating this data so that it is reliable i.e ordered, no duplicates etc I am using CakePHP framework on a LAMP environment, however, I think this question relates to all programming languages. My approach so far is to query the search API of each provider and then populate a MySQL table. From this the results are ordered, paginated etc. However, my concern is performance: API communication, parsing, inserting and then reading all in one execution. Am I missing something, does anyone have any other ideas? I'm sure this is a common problem with many alternative solutions. Any help would be greatly appreciated. Thanks, Paul

this operation has been canceled due to restrictions in effect on this computer

- by Dan

I have this HUGELY irritating problem on Windows 7 (x64). Whenever I click on ANY link (that exists on a Word document, excel or Outlook), I get an alert box with the message: "This operation has been canceled due to restrictions in effect on this computer" I have been scouring my settings and the internet for a solution, but to no avail. Has anybody else encounted this problem? It even happens when I click anchors in word documents i.e. I can't even click on an entry in a Table of Contents to go to the appropriate page - I get this same error then. Is this a Windows 7 thing? Anyway to turn this off?

Visual C# 2010 express... displaying console output??

- by ClarkeyBoy

Hi, I am currently creating a customer application for a local company. I have a datagridview linked to the customers table, and I am trying to link it up so that updates, inserts and deletions are handled correctly. I am very new to c# so I am starting with the basics (like about 2 days ago I knew nothing - I know vb.net, Java and several other languages though..). Anywho from what I understand anything output through Debug.WriteLine should only appear when in debug mode (common sense really) but anything output through Concole.WriteLine should appear whether or not in debug mode. However I have checked the immediate and output windows and nothing is being output when in normal mode. Does anyone have any idea why this is?? Thanks in advance, Richard

HTML CSS two columns

- by Marki

If my HTML says something along the following <div class="container"> <div class="element"> </div> <div class="element"> </div> [...] <div class="element"> </div> </div> is it then possible to align those elements as if they were in a two-column table? I.e. with 7 elements there would be 4 rows, with the last row only having one element. (The elements themselves have NO special classes or ids like right,left,etc.)

How can I return default at loop end in Scheme?

- by Kufi Annan

I'm trying to implement back-tracking search in Scheme. So far, I have the following: (define (backtrack n graph assignment) (cond (assignment-complete n assignment) (assignment) ) (define u (select-u graph assignment)) (define c 1) (define result 0) (let forLoop () (when (valid-choice graph assignment c) (hash-set! assignment u c) (set! result (backtrack n graph assignment)) (cond ((not (eq? result #f)) result)) (hash-remove! assignment u) ) (set! c (+ c 1)) (when (>= n c) (forLoop)) ) #f ) My functions assignment-complete and select-u pass unit tests. The argument assignment is a hash-table make with (make-hash), so it should be fine. I believe the problem I have is related to returning false at the end of the loop, if no recursive returns a non-false value (which should be a valid assignment).

Unable to reverse seemingly simple rails migration - getting "altered_table.column may not be NULL"

- by brad

I have a table 'invoices' in my development database (sqlite3) populated with a small amount of test data. I wanted to add a column 'invoice_number' to it and set up a migration like so: class AddInvoiceNumberColumnToInvoices < ActiveRecord::Migration def self.up add_column :invoices, :invoice_number, :integer end def self.down remove_column :invoices, :invoice_number end end I ran rake db:migrate and it seemed to migrate just fine. However, when I tried to access this column through ActiveRecord it didn't seem to be there. I decided to undo this migration and try again (not sure what I was going to try but I thought I'd start by undoing it) with rake db:migrate VERSION='whatever_the_migration_before_this_one_was_called'. This failed with the error message == AddInvoiceNumberColumnToInvoices: reverting =============================== -- remove_column(:invoices, :invoice_number) rake aborted! An error has occurred, this and all later migrations canceled: altered_invoices.invoice_number may not be NULL I can't find any documentation of this error. Is anyone able to explain what I have done wrong, and more importantly how I can fix this?

Editable QTreeView with expandable cells

- by serge

Hi everyone, I tried to write an editable table based on QTreeView with wordwraped content in cells which in turn should expand in height (that whole text was visible) like usual cells in tables like in MSWord, but have met insuperable obstacles: first - i can't set fixed cell size. second - i can't make text display in cells wordwraped. For this i used void QTreeWidget::setItemWidget ( QTreeWidgetItem * item, int column, QWidget * widget ), but it works only for readonly solutions. And i haven't come up with any other idea. Can such behavior of QTreeView be realized? And how to solve those problems of mine? Thanks in advance Serge

SSIS - How do I see/set the field types in a Recordset?

- by thursdaysgeek

I'm looking at an inherited SSIS package, and a stored procedure is sending records to a recordset called USER:NEW_RECORDS. It's of type Object, and the value is System.Object. It is then used for inputting that data to a SQL table. We're getting an error, because it seems that the numeric results of the stored procedure are being put in a DT_WSTR field, and then failing when it is then put into a decimal field in the database. Most of the records are working, but one, which happens to have a longer number of decimal digits, is failing. I want to see exactly what my SSIS recordset field types are, and probably change them, so I can force the data to be truncated properly and copied. Or, perhaps, I'm not even looking at this correctly. The data is put into the recordset using a SQL Task that executes the stored procedure.

SQL Self Join Query Help

- by hdoe123

Hi All, I'm trying to work out a query that self join itself on a table using the eventnumber. I've never done a self join before. What i'm trying to query is when a client has started off in a city which is chester to see what city they moved to. But I dont want to be able to see if they started off in another city. I would also like be only see the move once (So i'd only like to see if they went from chester to london rather then chester to london to wales) The StartTimeDate is the same EndDateTime if they moved to another city. Data example as follows if they started off in the city chester :- clientid EventNumber City StartDateTime EndDateTime 1 1 Chester 10/03/2009 11/04/2010 13:00 1 1 Liverpool 11/04/2010 13:00 30/06/2010 16:00 1 1 Wales 30/07/2010 16:00 the result I would like to see is on the 2nd row - so it only shows me liverpool. Could anyone point in the right direcetion please?

Debugging SQL in PGAdmin3 when sql contains variables

- by Mr Shoubs

In SQL Server I could copy sql code out of an application and paste it into SSMS, declare & assign vars that exist in the sql and run.. yay great debugging scenario. e.g. (please note I am rust and syntax may be incorrect) declare @x as varchar(10) set @x = 'abc' select * from sometable where somefield = @x I want to do something simular with postgres in pgadmin3 (or another postgres tool, anyy reccomendations?) I realise you can create pgscript, but it doesn't appear to be very good, for example, if I do the equlivent of above, it doesn't put the single quotes around the value in @x, nor does it let me by doubling them up and you don't get a table out after - only text... Currently I have a peice of sql someone has written that has 3 unique varibles in it which are used around 6 times each... So the question is how do other people debug sql this sql EFFICIENTLY, preferably in a simular fashion to my sql server days.

Does it take time to deallocate memory?

- by jm1234567890

I have a C++ program which, during execution, will allocate about 3-8Gb of memory to store a hash table (I use tr1/unordered_map) and various other data structures. However, at the end of execution, there will be a long pause before returning to shell. For example, at the very end of my main function I have std::cout << "End of execution" << endl; But the execution of my program will go something like $ ./program do stuff... End of execution [long pause of maybe 2 min] $ -- returns to shell Is this expected behavior or am I doing something wrong? I'm guessing that the program is deallocating the memory at the end. But, commercial applications which use large amounts of memory (such as photoshop) do not exhibit this pause when you close the application. Please advise :)

NamedParameterJdbcTemplate jconnect decimal issue

- by user1052849

I am using NamedParameterJdbcTemplate to insert data into a table. (Spring 2.5.3/Java 1.6) I am using jconnect driver to connect to sybase jdbc:sybase:Tds:<Server>:<Port>. For some reason the decimal values the decimal part is truncated. With the same code if I use jtds driver (jdbc:jtds:sybase://<Servername>:<Port>) its working fine. I cannot use jtds as jconn is being used by other code. In Java objects, field is defined as double. In database, field is defined as float (numeric with precision does not work). Any help is appreciated.
