• UITableView: Highlighted cell after switching back views

  - by Matthias

  Hi, I'm using a UINavController together with some UITableViews to display a kind of drill down for some data (e.g. like the Contact App). Works well. The only problem I have is, when I select a cell in the first table view it is highlighted, then the view switches to the next level and then, if I go back to the first level, the cell is still highlighted. So, how can I reset the highlighting when switching back? Thanks for your help. Regards Matthias

• Taking 2 attributes from XElement to create a dictionary LINQ

  - by AndyC

  I'm trying to take one attribute to use as the key, and another to use as the value. If I use (xDoc is an XDocument object in the example): Dictionary<string, XElement> test = xDoc.Descendants() .Where<XElement>(t => t.Name == "someelement") .ToDictionary<XElement, string>(t => t.Attribute("myattr").Value.ToString()); I get a dictionary with the myattr value as key (which is what I want) but the entire XElement object as the value. What I want to do, is to select a second attribute to set as the value property on each dictionary item, but can't seem to figure that out. Is it possible to do all of this in 1 Linq statement? Curiousity has caught me! Cheers!

• Echo-ing Only Available Database Result

  - by Robert Hanson

  I have this Associative Array : $Fields = array("row0"=>"Yahoo ID", "row1"=>"MSN ID", "row2"=> "Gtalk ID"); on the other side, I have this SQL query : SELECT YahooID, MSNID, GTalkID From UserTable WHERE Username = '$Username' LIMIT 1; the result maybe vary, because some users only have Yahoo ID and some have others. for example if I have this result : $row[0] = NONE //means YahooID = NONE $row[1] = [email protected] $row[2] = [email protected] then how to have this as an output (echo) : MSN ID = [email protected] Gtalk ID = [email protected] since Yahoo ID is not exist, then the result will be MSN and Gtalk only. 'MSN ID' and 'Gtalk ID' is variable from Associative Array, while '[email protected]' and '[email protected]' from SQL result. thanks!

• VB.NET Loacalization

  - by PandaNL

  In my winform app in VB.NET i want to use the localization option. But i have a few questions/problems. I'm using a menu strip to select an other language. But it seems that is doesn't change my menustip text to my selected language. It does change my labels, buttons, and textboxes but menu strips doesnt seem to change when i choose an other language. Also is it possible to get those resx files such as MyForm.fr-FR.resx compiled so it isn't an external file outside my app? Or to get those files in an Language folder at the same location of my app, so i don't have all those fr-FR, nl-Nl folders in the same location as my program.

• data type trouble in php

  - by user225269

  I don't know why but the data type in this code makes a trouble when the id in the url starts with the number zero like this: http://localhost/exp/update.php?id=03A43 In this case the id is 03A43. And my query looks like this: mysql_select_db("school", $con); $result = mysql_query("SELECT * FROM student WHERE IDNO=".(int)$_GET['id']); ?> There is no problem in the design if the id does not start with the number zero. What might be the proper data type for numbers beginning in zero?

• MySQL - Counting rows in preparation for greatest-n-per-group not working?

  - by John M

  Referring to SO and other sites have given me examples of how to use MySQL to create a 'greatest-n-per-group' query. My variant on this would be to have a query that returns the first 3 rows of each category. As the basis for this I need to sort my data into a usable sequence and that is where my problems start. Running just the sequence query with row numbering shows that changes in category are mostly ignored. I should have 35 categories returning rows but only 5 do so. My query: set @c:=0; set @a:=0; SELECT IF(@c = tdg, @a:=@a+1, @a:=1) AS rownum, (@c:=tdg) , julian_day, sequence, complete, year, tdg FROM tsd WHERE complete = 0 order by tdg, year, julian_day, sequence Do I have a syntax mistake with this query?

• Convert unusual string into date time

  - by BlueChippy

  I have a system that outputs dates in the format "1{yy}{MM}{dd}" and I am trying to find a good way to parse it back into a real date. At the moment I am using this: var value = "1110825"; var z = Enumerable.Range(1,3).Select(i => int.Parse(value.Substring(i, 2))).ToList(); var d = new DateTime(2000 + z[0], z[1], z[2]); but I'm sure there's a cleaner/more efficient way to do it? I've tried DT.ParseExact, but can't find a suitable format string to use.

Please suggest accordingly. Thanks in advance

• Visual Studio 2005 Build Order

  - by user77826

  I have a Web Application. Sometimes I want to debug a console app that is within the solution. Why is it that when I right click on it and select debug, it builds every single webpage and libraries, which takes a while. When I look at build dependencies for the console app, it lists everything in the solution as the order and tells me to go to build order to change it. In build order, everything checks out... I only have checked the libraries that this console app needs. I also tried setting this console app as a start up project. Same thing... How do I get it so when I want to debug this console app, it only builds that and runs instead of building the entire solution before running?

• Getting differences between collections in LINQ

  - by dotnetdev

  Hi, I have a collection of image paths, and a larger collection of Image objects (Which contain a path property). I have the code to check for any matching images, but if there are supposed to be four matching image paths (as that is how many are in the first collection), and there is less than this, how can I get the missing one without writing loops? List<string> ImagesToCheck = new List<string>() { "", "s", "ssdd" }; IEnumerable<HtmlImage> Images = manager.ActiveBrowser.Find.AllControls<HtmlImage>(); var v = from i in Images where ImagesToCheck.Any(x => x == i.Src) select i; if (v.Count() < 3) { } So I need to get the items which are not in the collection titled v, but are in ImagesToCheck. How could I do this with LINQ? Thanks

• Drupal subscriptions to taxonomy only

  - by Disco

  Playing around with the subscriptions module; i have some troubles getting it to send the right notification for right subscription. Here's the situation : I have a content-type of type 'work'; it has a cck-taxonomy field; when creating the content users choses one category in which his 'work' fulfills. In user profil, under Categories (user/3/subscriptions/taxa) I choose two categories, lets say 'house work' and 'car work'. When creating a new 'work' content I do not get the notification. But, when manually select 'content-type' in user's profile of type 'work' I get the notification e-mail but independant to which 'category' i had chosen. This is quite annoying since I only want the user to receive his notifications upon the taxonomy he has chosen, not for every new content of type 'work'. Am I missing something obvious here ?

• Rails: Best practice to store user settings?

  - by ole_berlin

  Hi, I'm wondering what the best way is to store user settings? For a web 2.0 app I want users to be able to select certain settings. At the moment is it only when to receive email notifications. The easiest way would be to just create a Model "Settings" and have a column for every setting and then have a 1-1 relationship with users. But is there a pattern to solve this better? Is it maybe better to store the info in the user table itself? Or should I use a table with "settings_name" and "settings_value" to be completely open about the type of settings stored there (without having to run any migrations when adding options)? What is your opinion? Thanks

• Codeigniter - selecting children and parents from db

  - by Tomek Buszewski

  I want to pull from my database records corresponding to parent_id, like this: function getChildren($id, $parent_id) { $q = $this->db->select('id, name, slug, plat'); $q = $this->db->from('games'); $q = $this->db->where('parent_id',$id); $q = $this->db->or_where('id',$parent_id); $q = $this->db->get(); return $q->result_array(); } It - if it's a children game - get parent_id and search for a game with such id and for other games that has parent_id same as this one. If it's the parent game, it only looks for games with parent_id same as it's id. The problem is... it's not always working. I have four games in db: id | parent_id | title 15 | 0 | Abe 19 | 15 | Abe 20 | 0 | RE2 21 | 20 | RE2 DS First two works, last two - only children (id = 21) shows parent.

• Show data relationship in gridview with dropdownlist or similar?

  - by Anders Svensson

  I have data coming from two tables with a foreign key relationship - one User table containing users of the web application, and one Page table containing details about pages visited by each user. I would like to be able to view these data in a gridview or the like on a page. It's easy enough to just show the User table data like so (I'm using the Entity Framework and LINQ): UserDBEntities context = new UserDBEntities(); GridView1.DataSource = from user in context.UserSet select new { user.Ip, user.Count, user.Description, user.Referer }; GridView1.DataBind(); But how can I show the Page details? I'm not bent on any particular way of showing it, but the only idea I've been able to come up with is to have a dropdown list for each user in a column. But I can't figure out how to get the page data into such a dropdown list. The tables are associated with the primary/foreign key UserID. Any ideas would be welcome (dropdownlist solution or other)!

• Passing a column name instead of index in sqlite3

  - by user271753

  The problem code: NSString *query = @"SELECT Name FROM Category"; sqlite3_stmt *statement; if (sqlite3_prepare_v2(database, [query UTF8String], -1, &statement, nil) == SQLITE_OK) { while (sqlite3_step(statement) == SQLITE_ROW) { char *row =(char *)sqlite3_column_text(statement,0); char *rowData = (char *)sqlite3_column_text(statement,1); NSString *fieldName = [[NSString alloc] initWithUTF8String:row]; NSString *fieldValue = [[NSString alloc] initWithUTF8String:rowData]; NSLog(@"%@",fieldName); NSLog(@"%@",fieldValue); [fieldName release]; [fieldValue release]; } sqlite3_finalize(statement); } char *row =(char *)sqlite3_column_text(statement,0); In the above code instead of 0 can't I just pass a column name? How can I do that ?

• How can I Include Multiples Tables in my linq to entities eager loading using mvc4 C#

  - by EBENEZER CURVELLO

  I have 6 classes and I try to use linq to Entities to get the SiglaUF information of the last deeper table (in the view - MVC). The problem is I receive the following error: "The ObjectContext instance has been disposed and can no longer be used for operations that require a connection." The view is like that: > @model IEnumerable<DiskPizzaDelivery.Models.EnderecoCliente> > @foreach (var item in Model) { > @Html.DisplayFor(modelItem => item.CEP.Cidade.UF.SiglaUF) > } The query that i use: var cliente = context.Clientes .Include(e => e.Enderecos) .Include(e1 => e1.Enderecos.Select(cep => cep.CEP)) .SingleOrDefault(); The question is: How Can I improve this query to pre loading (eager loading) "Cidade" and "UF"? See below the classes: public partial class Cliente { [Key] [DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)] public int IdCliente { get; set; } public string Email { get; set; } public string Senha { get; set; } public virtual ICollection<EnderecoCliente> Enderecos { get; set; } } public partial class EnderecoCliente { public int IdEndereco { get; set; } public int IdCliente { get; set; } public string CEPEndereco { get; set; } public string Numero { get; set; } public string Complemento { get; set; } public string PontoReferencia { get; set; } public virtual Cliente Cliente { get; set; } public virtual CEP CEP { get; set; } } public partial class CEP { public string CodCep { get; set; } public string Tipo_Logradouro { get; set; } public string Logradouro { get; set; } public string Bairro { get; set; } public int CodigoUF { get; set; } public int CodigoCidade { get; set; } public virtual Cidade Cidade { get; set; } } public partial class Cidade { public int CodigoCidade { get; set; } public string NomeCidade { get; set; } public int CodigoUF { get; set; } public virtual ICollection<CEP> CEPs { get; set; } public virtual UF UF { get; set; } public virtual ICollection<UF> UFs { get; set; } } public partial class UF { public int CodigoUF { get; set; } public string SiglaUF { get; set; } public string NomeUF { get; set; } public int CodigoCidadeCapital { get; set; } public virtual ICollection<Cidade> Cidades { get; set; } public virtual Cidade Cidade { get; set; } } var cliente = context.Clientes .Where(c => c.Email == email) .Where(c => c.Senha == senha) .Include(e => e.Enderecos) .Include(e1 => e1.Enderecos.Select(cep => cep.CEP)) .SingleOrDefault(); Thanks!

• How to read changed values with native query during one transaction? (Spring and JPA)

  - by knarf1983

  We have container transaction with Spring and JPA (Hibernate). I need to make an update on a table to "flag" some rows via native statements. Then we insert some rows via EntityManager from JPATemplate to this table. After that, we need to calculate changes in the table via native statement (with Oracle's union and minus, complex groups...) I see that changes from step 1 and 2 are not commited and thats why the statement from 3 fails. I already tried with transaction propagation REQUIRES_NEW, EntityManager.flush... Didn't work. 1) update SOMETABLE acolumn = somevalue (native) 2) persist some values into SOMETABLE (via entity manager) 3) select values from SOMETABLE Is there a possibility to read the changes from step 1 and 2 in step 3?

• MYSQL - Adding result set A to result set B? Please see my example

  - by BlackberryFan

  I have two mysql tables. They are laid out in this manner: user_info id | emailContact _______________________ 1 | [email protected] 3 | [email protected] user_biz_info id | emailContact _________________________ 8 | [email protected] 9 | [email protected] What kind of join would I use to create a result set of information like this: id | emailContact ________________________________ 1 - [email protected] 3 - [email protected] 8 - [email protected] 9 - [email protected] I have tried the following: SELECT p.id, p.emailContact, b.id, b.emailContact FROM user_info p, user_business_info b But it seems that this is an incorrect approach. Would someone be able to suggest the correct approach in this or possibly point me in the direction of some tutorials that cover this type of mysql join, as this is what I assume is needed in this case. Thanks for your time in reading through my question!!

• Uniquely identifying mobile devices over a network for webforms

  - by Eric

  I'm designing a system for mobile devices that can be assigned only to one job at a time. So I need to be able to know which mobile device is being used by accessing it's own unique static IP address or its device ID. I don't want to assign an ID myself for every machine that comes in which is why a static IP would work great. However, in trying to retrieve the client ip address I'm retrieving the wireless router's ip or some other ip which is not the mobile device's ip. I want to store that ip in a table and control which jobs are assigned to it. How can I accomplish this? I've tried the following but I'm getting the wireless ip: var hostEntry = Dns.GetHostEntry(Dns.GetHostName()); var ip = ( from addr in hostEntry.AddressList where addr.AddressFamily.ToString() == "InterNetwork" select addr.ToString() ).FirstOrDefault(); I'd rather not set a cookie if there exists a better alternative. TIA!

• Commenting system for CakePHP blog tutorial

  - by Ryan

  I'm building off the CakePHP tutorial for the blog engine by adding comments to each post. I am able to add comments by selecting the post that it should be attached to, via a select box. I would like to be able to click an "Add Comment" link within the post and have the association to the post formed programatically. I am unsure how I can pass the post_id to the add method within my comments_controller. The body of my add method is the auto-generated scaffold code. Is it as easy as adding a $postId argument to the add method and write this to the post_id in my comments model? This doesn't feel right though, since I would expect add to be called when my submit button is click on my comments add view. Thanks all.
