  • Add blank cell at end of UITable

    - by Michael
    I'm trying to add an additional cell for custom content as the last cell in a tableView, without altering the dictionary that creates the other content of the table. I think the place to add it is in cellForRowAtIndexPath rather than adding one to the numberOfRowsInSection, which just crashes if I do. I get a cellCount from the dictionary that creates the data for the table, then in cellForRowAtIndexPath, I have: if (indexPath.row == cellCount) { ... stuff goes here return cell; } of course, this never gets called. If I do if (indexPath.row == cellCount -1) it overwrites the last cell with content. I can get this to work if I add a blank entry into the xml from which I am populating the dictionary, but that's ugly. Example code would be neat!

  • Logging into table in MS SQL trigger

    - by Martin
    I am coding MS SQL 2005 trigger. I want to make some logging during trigger execution, using INSERT statement into my log table. When there occurs error during execution, I want to raise error and cancel action that cause trigger execution, but not to lose log records. What is the best way to achieve this? Now my trigger logs everything except situation when there is error - because of ROLLBACK. RAISERROR statement is needed in order to inform calling program about error. Now, my error handling code looks like: if (@err = 1) begin INSERT INTO dbo.log(date, entry) SELECT getdate(), 'ERROR: ' + out from #output RAISERROR (@msg, 16, 1) rollback transaction return end

  • Linq to NHibernate using Queryable.Where predicate

    - by Groo
    I am querying an SQLite database using LINQ to NHibernate. Person is an entity containing an Id and a Name: public class Person { public Guid Id { get; private set; } public string Name { get; private set; } } Let's say my db table contains a single person whose name is "John". This test works as expected: var query = from item in session.Linq<Person>() where (item.Name == "Mike") select item; // no such entity should exist Assert.IsFalse(query.Any()); but this one fails: var query = from item in session.Linq<Person>() select item; query.Where(item => item.Name == "Mike"); // following line actually returns the // "John" entry Assert.IsFalse(query.Any()); What am I missing?

  • Can I use a class as an object in .NET to create instances of that class?

    - by Troy
    I'm writing a fairly uncomplicated program which can "connect" to several different types of data sources including text files and various databases. I've decided to implement each of these connection types as a class inherited from an interface I called iConnection. So, for example, I have TextConnection, MySQLConnection, &c... as classes. In another static class I've got a dictionary with human-readable names for these connections as keys. For the value of each dictionary entry, I want the class itself. That way, I can do things like: newConnection = new dict[connectionTypeString](); Is there a way to do something like this? I'm fairly new to C# so I'd appreciate any help.

  • Basic Login Script using php and mysql inquiry

    - by Matt
    Attempting to write a check for a login script to see if the username is available. Would the best way to write this query be to check if isset(!_POST[]) for both values (nick and pass) then connect to database WHERE the mysql database for the usernick requested return the user id if the usernick exists evaluate if isset($id) to see if the user name is taken and use that to continue to creating an entry Does this logically sound like a method to check for login without using excessive code sorry for not posting the code, it is on another computer and this computer is locked down by my administrator at work... Also, is there another way to evaluate if a value exists in the database? For instance, instead of setting $id to the return value of the mysql database can i just ping the mysql database for the information and have it return a Boolean result so I am not putting out any user information. Thanks, Matt

  • Can I make DataGridView.EndEdit trigger the CellValidating event?

    - by Don Kirkby
    I'm using a DataGridView in my WinForms application. My main objective is to make the Enter key not move to the next row in the grid. I still want the enter key to validate and end edit mode. I found this FAQ entry and subclassed DataGridView to override ProcessDialogKey(). If the key pressed is Enter, I call EndEdit(), otherwise I call base.ProcessDialogKey(). It works great, except the CellValidating event isn't fired. Currently, I'm just manually calling my validation logic before I call EndEdit, but it seems like I'm missing something. I guess I could call OnCellValidating, but then I'd be worried I'm missing some other event. What I really want is some flavour of EndEdit() that behaves just like pressing enter on the last row of a grid with adding disabled.

  • How to structure a multilingual website for search engines?

    - by Nirmal
    I have this website which decides on the display language by a GET parameter. http://www.mysite.com/index.php?page=home&locale=en which is rewritten as http://www.mysite.com/en/home When no language is specified, the system defaults to English (en). Now how do I tell the search engines that many versions of the website exist? When the search bot enters the site, it will trigger the default English Language and after finishing, will just leave the site without considering other languages. I can very well have a sitemap with links to the default pages of each language, so the bot can navigate from there. But how do I say the bot that the entry in the sitemap is the home page for that language? Like if someone searches for 'mi sitio', they should be presented with the result http://www.mysite.com/es/home and not some other internal page. Any light on this? Thanks.

  • Change .NET Framework version of application pool to 3.5?

    - by Sean Sexton
    I've installed .NET Framework 3.5 SP1 on web server (Server 2008 Enterprise), so running IIS 7.0. I want to change the version of .NET Framework used by an existing site. So I right-click on appropriate Application Pool and selected Edit Application Pool. The .NET Framework dropdown does not include an explicit entry for framework 3.5, but just 2.0.50727. Does anyone know off the top of their head--is this just because the version of the core RTL in 3.5 is still 2.0? Or do I need to do something additional to get IIS to see version 3.5? (Did try restarting IIS). Thanks!

  • AVG time spent on multiple rows SQL-server?

    - by seo20
    I have a table tblSequence with 3 cols in MS SQL: ID, IP, [Timestamp] Content could look like this: ID IP [Timestamp] -------------------------------------------------- 4347 62.107.95.103 2010-05-24 09:27:50.470 4346 62.107.95.103 2010-05-24 09:27:45.547 4345 62.107.95.103 2010-05-24 09:27:36.940 4344 62.107.95.103 2010-05-24 09:27:29.347 4343 62.107.95.103 2010-05-24 09:27:12.080 ID is unique, there can be n number of IP's. Would like to calculate the average time spent per IP. in a single row Know you can do something like this: SELECT CAST(AVG(CAST(MyTable.MyDateTimeFinish - MyTable.MyDateTimeStart AS float)) AS datetime) But how on earth do I find the first and last entry of my unique IP row so I can have a start and finish time? I'M stuck. Would like to calculate the average time spent per IP. in a single row

  • disable text drag and drop

    - by maniek
    There is a common feature of modern browsers where a user can select some text and drag it to an input field. Within the same field it causes moving of text, between different fields it does copying. How do I disable that? If there is no portable way, I am mostly interested in firefox. This is an intranet webapp, so I am also interested in modifying the browser/getting a plugin to do this. Maybe some system-level settings (I`m on windows XP)? I need to keep the default select-copy-paste functionality. The background is I have multiple-field data entry forms, and users often drag something by mistake.

  • C++/MFC: Handling multiple CListCtrl's headers HDN_ITEMCLICK events

    - by raph.amiard
    I'm coding an MFC application in which i have a dialog box with multiple CListCtrls in report view. I want one of them to be sortable. So i handled the HDM_ITEMCLICK event, and everything works just fine .. Except that if i click on the headers of another CListCtrl, it does sort the OTHER CListCtrl, which does look kind of dumb. This is apparently due to the fact that headers have an ID of 0, which make the entry in the message map look like this : ON_NOTIFY(HDN_ITEMCLICK, 0, &Ccreationprogramme::OnHdnItemclickList5) But since all the headers have an id of zero, apparently every header of my dialog sends the message. Is there an easy way around this problem ?

  • SimpleXML adding html into Hash tree

    - by Miriam Raphael Roberts
    Question: I have an xml file that I am pulling from the web and parsing. One of the items in the xml is a 'content' value that has HTML. I am using SimpleXML/XMLin to parse the file like so: $xml= eval { $data-XMLin($xmldata, forcearray = 1, suppressempty= +'') }; When I use Dumper to dump the hash, I dsicovered that SimpleXML is parsing the HTML into the hash tree. 'content' => { 'div' => [ { 'xmlns' => 'http://www.w3.org/1999/xhtml', 'p' => [ { 'a' => [ { 'href' => 'http://miamiherald.typepad.com/.a/6a00d83451b26169e20133ec6f4491970b-pi', 'style' => 'FLOAT: left', 'img' => [ etc..... This is not what I want. I want to just grab content inside of this entry. How do I do this?

  • Import text file crunching library for Java/Groovy ?

    - by devdude
    In a lot of real life implementations of applications we face the requirement to import some kind of (text) files. Usually we would implement some (hardcoded?) logic to validate the file (eg. proper header, proper number of delimiters, proper date/time value,etc.). Eventually also need to check for the existence of related data in a table (eg. value of field 1 in text file must have an entry in some basic data table). While XML solves this (to some extend) with XSD and DTD, we end up hacking this again and again for proprietary text file formats. Is there any library or framework that allows the creation of templates similar to the xsd approach ? This would make it way more flexible to react on file format changes or implement new formats. Thanks for any hints Sven

  • How do I find the top N batters per year?

    - by Drew Stephens
    I'm playing around with the Lahman Baseball Database in a MySQL instance. I want to find the players who topped home runs (HR) for each year. The Batting table has the following (relevant parts) of its schema: +-----------+----------------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-----------+----------------------+------+-----+---------+-------+ | playerID | varchar(9) | NO | PRI | | | | yearID | smallint(4) unsigned | NO | PRI | 0 | | | HR | smallint(3) unsigned | YES | | NULL | | +-----------+----------------------+------+-----+---------+-------+ For each year, every player has an entry (between hundreds and 12k per year, going back to 1871). Getting the top N hitters for a single year is easy: SELECT playerID,yearID,HR FROM Batting WHERE yearID=2009 ORDER BY HR DESC LIMIT 3; +-----------+--------+------+ | playerID | yearID | HR | +-----------+--------+------+ | pujolal01 | 2009 | 47 | | fieldpr01 | 2009 | 46 | | howarry01 | 2009 | 45 | +-----------+--------+------+ But I'm interested in finding the top 3 from every year. I've found solutions like this, describing how to select the top from a category and I've tried to apply it to my problem, only to end up with a query that never returns: SELECT b.yearID, b.playerID, b.HR FROM Batting AS b LEFT JOIN Batting b2 ON (b.yearID=b2.yearID AND b.HR <= b2.HR) GROUP BY b.yearID HAVING COUNT(*) <= 3; Where have I gone wrong?

  • Does a System.DirectoryServices.AccountManagement.Principal ever have a null GUID?

    - by Josh
    I have a situation where I need to store a globally unique identifier that points to an Active Directory user account. I'm leaning towards the Guid because it is easier to store than the Sid. According to the MSDN entry, the property (which is a Nullable), will always return null if the ContextType is set to "Machine." I don't need to worry about this because our ContextType will always be set to "Domain." My question is, will this property ever return null if the ContextType is "Domain"? In other words, will an account in an AD DS store always have a Guid?

  • How to track different button clicks with Google Analytics and AJAX?

    - by citronas
    I have several pages, let's call them A, B and C. Each of these pages has a form where the user can type in some information and click a button to send those information to the server. This button click is performed in an UpdatePanel to prevent a full postback. A customer of ours now wants to know how many % of the using visiting each site (A, B and C have different URLs) use this form. (Meaning I need seperate values for A, B and C) How to I track this in Google Analytics? It seems that I have to create a conversion(??) for each page. Is that correct? How must I modify the existing web application to let Google Analytics know, that a user submitted the form. (without the need to redirect thank to xy amount of different thank you pages) The only piece of information I've found so far is this: http://www.google.com/support/googleanalytics/bin/answer.py?hl=en&answer=55519 Unfortunately, this FAQ entry does not cover my answer.

  • help with exception handling in linq

    - by stackoverflowuser
    I have the following code to retrieve customer name, total (orders ), sum (order details) for reach customer in Northwind database. The problem with below code is that it raises an exception since a few customers dont have any entry in orders table. I know using the query syntax (join) the exception can be avoided. I want to know if the same can be handled with the extension method syntax. CustomerOrderDataContext db = new CustomerOrderDataContext(); var customerOrders = db.Customers.Select(c => new { CompanyName = c.CompanyName, TotalOrders = c.Orders.Count(), TotalQuantity = c.Orders.SelectMany(o => o.Order_Details).Sum(o=>o.Quantity) });

  • Continuously checking database from a Windows service

    - by JonF
    I am making a Windows service which needs to continuously check for database entries that can be added at any time to tell it to execute some code. It is looking to see if it's status is set to pending, and it's execute time entry is than the current time. Is the only way to do this to just run select statements over and over? It might need to execute the code every minute which means I need to run the select statement every minute looking for entries in the database. I'm trying to avoid unneccesary cpu time because I'm probably going to end up paying for cpu cycles on the hosting provider

  • Visual Studio Add-in - How do I create an Installer?

    - by Morgeh
    I have made a Visual Studio Add-in as part of a project I'm working on using web services. When I created the new Add-in project in visual studio it generated all the code required and installed the blank add-in on my pc (I assume). Since this is a large project we are using svn to manage the code base and once I had done some of the work on the Add-in I commited it, then checked it out on a different pc and attempted to run it. However on the other pc when I run the add-in in debug mode, the tools entry for the add-in is not present and I can't run the add-in. Am I right in assuming that when I created the project on the other pc it installed the plugin aswell?? and does that mean that I will need to create an installer for any other pcs I wish to use? Obviously at some point I intend on making an installer anyway but not untill after the development of the addin is complete.

  • Map a domain to an MVC area

    - by Simon_Weaver
    Anybody got any experience in mapping a domain to an MVC area? Here's our situation: Old system (still active but will soon redirect to new store): www.example.com - our main site where we send traffic store.example.com - our store site which is a completely separate site that is indexed in google New system: www.example.com - same site as before www.example.com/store - new store site - built in an ASP.NET MVC area Because store is a separate domain google gives it a separate entry in the search results. I'd like to keep this benefit in future but wondering whether or not there is a good way to map a domain (store.example.com) to the MVC area or if its just going to be more trouble than its worth. PS. I'm not trying to keep existing indexing - its a completely separate store so thats not possible. I just want to redirect to the corresponding page in the new store. I'm just trying not to lose the benefit of two domains for SEO purposes.

  • Factorial Algorithms in different languages

    - by Brad Gilbert
    I want to see all the different ways you can come up with, for a factorial subroutine, or program. The hope is that anyone can come here and see if they might want to learn a new language. Ideas: Procedural Functional Object Oriented One liners Obfuscated Oddball Bad Code Polyglot Basically I want to see an example, of different ways of writing an algorithm, and what they would look like in different languages. Please limit it to one example per entry. I will allow you to have more than one example per answer, if you are trying to highlight a specific style, language, or just a well thought out idea that lends itself to being in one post. The only real requirement is it must find the factorial of a given argument, in all languages represented. Be Creative! Recommended Guideline: # Language Name: Optional Style type - Optional bullet points Code Goes Here Other informational text goes here I will ocasionally go along and edit any answer that does not have decent formatting.

  • How to do manual DI with deep object graphs and many dependencies properly

    - by Fabian
    I believe this questions has been asked in some or the other way but i'm not getting it yet. We do a GWT project and my project leader disallowed to use GIN/Guice as an DI framework (new programmers are not going to understand it, he argued) so I try to do the DI manually. Now I have a problem with deep object graphs. The object hierarchy from the UI looks like this: AppPresenter-DashboardPresenter-GadgetPresenter-GadgetConfigPresenter The GadgetConfigPresenter way down the object hierarchy tree has a few dependencies like CustomerRepository, ProjectRepository, MandatorRepository, etc. So the GadgetPresenter which creates the GadgetConfigPresenter also has these dependencies and so on, up to the entry point of the app which creates the AppPresenter. Is this the way manual DI is supposed to work? doesn't this mean that I create all dependencies at boot time even I don't need them? would a DI framework like GIN/Guice help me here?

  • many to many query for ActiveRecord

    - by JP
    I have three data models, Users, Conversations and Lines, where each conversation has many lines and certain participating users, each line has one conversation and one user and each user has many conversations and many lines. I have arranged these in ActiveRecord like this: class Line < ActiveRecord::Base belongs_to :conversation belongs_to :user end class User < ActiveRecord::Base has_and_belongs_to_many :conversations has_many :lines end class Conversation < ActiveRecord::Base has_many :lines has_and_belongs_to_many :users end If I want to create a new conversation with 4 users, where the users are either found or created inside the users table, how would I go about doing this? I thought I could do: c = Conversation.new c.users.find_or_create_by_username('myUsername') c.save But this will create a new username in the Users table even if that username already exists! (ie. running the above code 3 times will result in Users having 3 rows with 'myUsername' as the username, one for each conversation, rather than three conversations all with the same 'myUsername' entry listed in their associated users) I'm not sure how to search for this kind of information with google - can anyone help?
