• [Iphone] - Problem in saving file using NSCoding

  - by Matte Gary

  Hi everybody, I've a problem with Iphone programming... I've a NSMutableArray containing object of type "MyClass". MyClass has some parameters, like NSNumber and NSString. I've followed the Apple Tutorial about coding and decoding object using NSCoding, but when I try to decode the file I've stored, the NSMutableArray contain object of type "MyClass", but with wrong parameters. I think i've done all I've to do (including protocol, including methods like initwithencode etc), but it's still not working... Any suggestions? Thanks a lot! And sorry for my English XD

• Confusion about MVC Routes

  - by yang

  What is the problem below? routes.MapRoute( "Default2", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "test" } // Parameter defaults ); routes.MapRoute( "Default1", // Route name "{controller}/{action}/{name}", // URL with parameters new { controller = "Home", action = "Report", name = "" } // Parameter defaults ); When I navigate to /home/index "id" parameter takes the default value of "test" but when I navigate to home/report the name parameter is null. In short, if the route definition is the first in the route table, then the parameter takes its default value. But the others below don't.

• Caching view-port based Geo-queries

  - by friism

  I have a web app with a giant Google Map in it. As users pan and zoom around on the map, points are dynamically loaded through AJAX call which include the viewport bounds (NE and SW corner coordinates) and some other assorted parameters. How do I cache these request for points? The problem is that the parameters are highly variable and (worst) not discrete i.e. floats with a lots of decimal places. I'm using ASP.NET-MVC/C#/LINQ2SQL/SQL-Server but the problem is not tied to that platform. This is the signature of the the relevant method: [AcceptVerbs(HttpVerbs.Post)] public JsonResult Data(string date, string categories, string ne_lat, string ne_lng, string sw_lat, string sw_lng)

  When I run this code def func(x, y, *w, **z): print x print y if w: print w if z: print z else: print "None" func(10,20, 1,2,3,{'k':'a'}) I get the result as follows. 10 20 (1, 2, 3, {'k': 'a'}) None But, I expected as follows, I mean the list parameters (1,2,3) matching *w, and dictionary matching **z. 10 20 (1,2,3) {'k':'a'} Q : What went wrong? How can I pass the list and dictionary as parameters? Added func(10,20, 10,20,30, k='a') seems to be working

• Where are my $_FILES? Ajax Uploading

  - by Richard Testani

  I've built a form to upload images, and processed with Prototype/PHP. $('image_upload').observe('submit', function() { var params = $H(); params.set('name', $('image_title').value); params.set('from', $('from_who').value); params.set('upload_file', $('upload_file').value); new Ajax.Request('/files/upload_process.php', { method:'post', parameters: params, onSuccess: function(r) { $('uploadbox').update('<img src="/images/interface/thankyou.png" />'); } }) }); The form itself sends the data to the server, but when I try to output print_r($_FILES['upload_file']); nothing appears, not even an empty array. If I output print_r($_POST), the parameters are sent properly, but only the file name of the image. So it seems the files themselves are not being sent along. How do I handle this? Thanks Rich

• C++ Ambiguous call to Overloaded Function (const variety)

  - by Joe

  After researching this online, I've only found solutions that don't apply to my problem, so please bear with me. Code snippet: typedef my_map_t<int const *, float> _test; my_map_t::const_iterator not_found = my_map_t::end(); if (_test.find(&iKeyValue) == not_found) { _test[iKeyValue] = 4 + 5; // not the actual code, but here for simplicity } The compiler complains that there's an ambiguous call to my_map_t::end(). This makes sense, because the only difference is the return type. Output: error C2668: 'std::_Tree<_Traits>::end' : ambiguous call to overloaded function Normally you can disambiguate the call by casting the parameters, but end() has no parameters. Any ideas?

• Click edit button twice in gridview asp.net c# issue

  - by Supriyo Banerjee

  I have a gridview created on a page where I want to provide an edit button for the user to click in. However the issue is the grid view row becomes editable only while clicking the edit button second time. Not sure what is going wrong here, any help would be appreciated. One additional point is my grid view is displayed on the page only on a click of a button and is not there on page_load event hence. Posting the code snippets: //MY Aspx code <Columns> <asp:TemplateField HeaderText="Slice" SortExpression="name"> <ItemTemplate> <asp:Label ID="lblslice" Text='<%# Eval("slice") %>' runat="server"></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:Label ID="lblslice" Text='<%# Eval("slice") %>' runat="server"></asp:Label> </EditItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Metric" SortExpression="Description"> <ItemTemplate> <asp:Label ID="lblmetric" Text='<%# Eval("metric")%>' runat="server"></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:Label ID="lblmetric" Text='<%# Eval("metric")%>' runat="server"></asp:Label> </EditItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Original" SortExpression="Type"> <ItemTemplate> <asp:Label ID="lbloriginal" Text='<%# Eval("Original")%>' runat="server"></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:Label ID="lbloriginal" Text='<%# Eval("Original")%>' runat="server"></asp:Label> </EditItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="WOW" SortExpression="Market"> <ItemTemplate> <asp:Label ID="lblwow" Text='<%# Eval("WOW")%>' runat="server"></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:Label ID="lblwow" Text='<%# Eval("WOW")%>' runat="server"></asp:Label> </EditItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Change" SortExpression="Market" > <ItemTemplate> <asp:Label ID="lblChange" Text='<%# Eval("Change")%>' runat="server"></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="TxtCustomerID" Text='<%# Eval("Change") %> ' runat="server"></asp:TextBox> </EditItemTemplate> </asp:TemplateField> <asp:CommandField HeaderText="Edit" ShowEditButton="True" /> </Columns> </asp:GridView> //My code behind: protected void Page_Load(object sender, EventArgs e) { } public void populagridview1(string slice,string fromdate,string todate,string year) { SqlCommand cmd; SqlDataAdapter da; DataSet ds; cmd = new SqlCommand(); cmd.CommandType = CommandType.StoredProcedure; cmd.CommandText = "usp_geteventchanges"; cmd.Connection = conn; conn.Open(); SqlParameter param1 = new SqlParameter("@slice", slice); cmd.Parameters.Add(param1); SqlParameter param2 = new SqlParameter("@fromdate", fromdate); cmd.Parameters.Add(param2); SqlParameter param3 = new SqlParameter("@todate", todate); cmd.Parameters.Add(param3); SqlParameter param4 = new SqlParameter("@year", year); cmd.Parameters.Add(param4); da = new SqlDataAdapter(cmd); ds = new DataSet(); da.Fill(ds, "Table"); GridView1.DataSource = ds; GridView1.DataBind(); conn.Close(); } protected void ImpactCalc(object sender, EventArgs e) { populagridview1(ddl_slice.SelectedValue, dt_to_integer(Picker1.Text), dt_to_integer(Picker2.Text), Txt_Year.Text); } protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e) { gvEditIndex = e.NewEditIndex; Gridview1.DataBind(); } My page layout This edit screen appears after clicking edit twice.. the grid view gets displayed on hitting the Calculate impact button.

• FFmpeg and qt, Unable to find a suitable output format for '>'

  Hi all, I'm trying to execute a ffmpeg operation through Qt I would like to execute this line : ./ffmpeg -t 10 -i temp1 -f mpeg - > temp2 When I execute through the terminal, it works perfectly fine.

• Ruby on Rails: What are partial hash arguments and full set arguments?

  - by williamjones

  I'm using asserts_redirected_to in my unit tests, and I'm receiving this warning: DEPRECATION WARNING: Using assert_redirected_to with partial hash arguments is deprecated. Specify the full set arguments instead. What is a partial hash argument, and what is a full set argument? These aren't terms that I've seen used in the Rails community before, and the only relevant results I can find on Google for these are in reference to this deprecation warning. Here is my code: assert_redirected_to :controller => :user, :action => :search also tried: assert_redirected_to({:controller => :user, :action => :search}) I might have guessed that it feels I'm missing some parameters or something like that, but the API documentation explicitly says that not all parameters need to be included: http://rails.rubyonrails.org/classes/ActionController/Assertions/ResponseAssertions.html

• Is it possible to use objects as function paremeters in EL with JBoss EL resolver?

  - by calavera.info

  There is this sentence in JBoss EL resolver online documentation: It's important to fully understand how this extension to EL works. When the page is rendered, the parameter names are stored (for example, hotel.id and user.username), and evaluated (as value expressions) when the page is submitted. You can't pass objects as parameters! But I had used objects as function parameters in my project before I accidentally read this hint and it worked! How is it possible? I'm afraid of that there is some magic now...

• Modify url for bookmarking using JavaScript

  - by jamesaharvey

  I'm exploring my options for modifying urls in the browser bar for bookmarking purposes. Ideally, I'd like to add querystring parameters and cannot determine if this is even possible. I don't want the page to refresh and want to add querystring values on link clicks, ajax calls, etc. If I can't add querystring parameters, then I'd like to add hash values (http:://someurl.com#hash-value). How should I go about doing this? Should I use plain JavaScript or a framework (jquery, prototype, etc.) and/or framework plugin.

• which collection should I use

  - by Masna

  Hello, I have a number of custom objects of type X. X has a number of parameters and must be unique in the collection. (I created my own equals method based on the custom parameters to examine this) In each object of type x, I have a list of objects y. I want to add/remove/modify easily an object y. For example: To write the add method, it would be something like add(objTypeX, objTypeY) I would check or the collections already has a objTypeX. If so: i would add the objTypeY to the already existing objTypeX else: i would create objTypeX and add objTypeY to this object. To modify an objTypeY, it would be something like(objTypeX, objTypeY, newobjTypeY) I would get objTypeX out of the collections and modify objTypeY to newobjTypeY Which collections should I use? I tried with hashset but i can get a specific object out of the list, without run down the list till I find that object. I develop this in vb.net 3.5

• How do these user/userParam references relate to the Customer and Account lookups?

• Mass-mailing without getting your domain banned

  - by Arpit

  I plan on sending an email to 10k+ email addresses (mostly gmail and yahoo) to announce the launch of my startup's product. I'm planning on using PHPMailer or PHPList to send out the mails. I've never mass-mailed before and had a few basic questions. I've already browsed through some of the other mass-mail threads on this forum but the questions remain hence a new thread. Are newsletters which are sent by so many other organizations sent out in a similar manner - using programs such as PHPMailer or PHPList? When would a GMail or a Yahoo blacklist my domain name - are there any set parameters - 1000 emails in an hour would result in getting banned or some such parameters? If yes, then what sort of settings should I take note of when sending the emails - any format of the email or spread out the 10+ emails over 2 days etc.? If a Gmail or a Yahoo blacklists your domain name - is there any way to get out of the blacklist?

• How to use a DHT for a social trading environment

  - by Lirik

  I'm trying to understand if a DHT can be used to solve a problem I'm working on: I have a trading environment where professional option traders can get an increase in their risk limit by requesting that fellow traders lend them some of their risk limit. The lending trader will can either search for traders with certain risk parameters which are part of every trader's profile, i.e. Greeks, or the lending trader can subscribe to requests from certain traders. I want this environment to be scalable and decentralized, but I don't know how traders can search for specific profile parameters when the data is contained in a DHT. Could anybody explain how this can be done?

• OutOfMemoryError calling XmlSerializer.Deserialize() - not related to XML size!

  - by Mike Atlas

  This is a really crazy bug. The following is throwing an OutOfMemoryException, for XML snippits that are very short (e.g., <ABC def='123'/>) of one type, but not for others of the same size but a different type: (e.g., <ZYX qpr='baz'/>). public static T DeserializeXmlNode<T>(XmlNode node) { try { return (T)new XmlSerializer(typeof(T)) .Deserialize(new XmlNodeReader(node)); } catch (Exception ex) { throw; // just for catching a breakpoint. } } I read in this MSDN article that if I were using XmlSerializer with additional parameters in the constructor, I'd end up generating un-cached serializer assemblies every it got called, causing an Assembly Leak. But I'm not using additional parameters in the constructor. It also happens on the first call, too, so the AppDomain is fresh. Worse yet, it is only thrown in release builds, not debug builds. What gives?

• Correct usage of Voldemort as key-value pair?

  - by zengr

  Hello, I am trying to understand, how can Voldermort be used? Say, I have this scenario: Since, Voldemort is a key-value pair. I need to fetch a value (say some text) on the basis of 3 parameters. So, what will be the key in this case? I cannot use 3 keys for 1 value right, but that value should be search able on the basis of those 3 parameters. Am I making sense? Thanks EDIT1 eg: A blog system. A user posts a blog: User's data stored: Name, Age and Sex The blog content (text) is stored. Now, I need to use Voldemort here, if a user searches from the front end for all the blog posts by Sex: Male Then, my code should query voldemort and return all the "blog content (text)" which have Sex as Male.

• Procedure or function expects parameter which was not supplied

  - by eftpotrm

  Driving me mad on a personal project; I know I've done this before but elsewhere and don't have the code. As far as I can see, I'm setting the parameter, I'm setting its value, the connection is open, yet when I try to fill the dataset I get the error 'Procedure or function expects parameter "@test" which was not supplied'. (This is obviously a simplified test! Same error on this or the real, rather longer code though.) C#: SqlCommand l_oCmd; DataSet l_oPage = new DataSet(); l_oCmd = new SqlCommand("usp_test", g_oConn); l_oCmd.Parameters.Add(new SqlParameter("@test", SqlDbType.NVarChar)); l_oCmd.Parameters[0].Value = "hello world"; SqlDataAdapter da = new SqlDataAdapter(l_oCmd); da.Fill(l_oPage); SQL: create procedure usp_test ( @test nvarchar(1000) ) as select @test What have I missed?

• Cross-reference between delphi records

  - by Paul-Jan

  Let's say I have a record TQuaternion and a record TVector. Quaternions have some methods with TVector parameters. On the other hand, TVector supports some operations that have TQuaternion parameters. Knowing that Delphi (Win32) does not allow for forward record declarations, how do I solve this elegantly? Using classes is not really an option here, because I really want to use operator overloading for this rare case where it actually makes good sense. For now I simply moved these particular methods out of the records and into separate functions, the good old-fashioned way. Better suggestions are most welcome.
