    I have List<Attributes> la = new List<Attributes>(); la = (from t in result let t1 = t.AttributeCollection from t2 in t1 where t2.AttributeCode.Equals(attributeType) let t3 = t2.TimeSeriesData from k in t3.ToList() where k.Key.Equals(startDate) && k.Key.Equals(endDate) select new { AttributeCode = attributeType, TimeSeriesData = fn(k.Key, k.Value.ToString()) }).ToList<Attributes>(); I am getting the error: 'System.Collections.Generic.IEnumerable<AnonymousType#1>' does not contain a definition for 'ToList' and the best extension method overload 'System.Linq.Enumerable.ToList<TSource>(System.Collections.Generic.IEnumerable<TSource>)' has some invalid arguments I understood tye error meaning but how to type cast it. I have used var and then iterating over it got the result. But without that any other way by which I can do it? Using C# 3.0 Thanks

  • Question about ASP.NET MVC and static data (ie. images, scripts, etc)

    - by Pure.Krome
    Hi folks, If i have a request for a resource in my ASP.NET MVC1 (or 2) web app for a static resource, say ... an image or a javascript file or a css file ... does the .NET framework try and see if the request matches the route list ... and eventually can't find a controller for it? eg. Resource: /Content/Images/Foo.png Does this request go through my route list .. fails to match any controllers / actions to this request and then .. i donno ... attempt that path directly?

  • Getting service unavailable message when sending messages to google xmpp using wokkel

    - by Code freak
    Hi, I made a wokkel (twisted python) bot to send and receive messages from the google xmpp service. Everything (auth, presence) etc works fine. One of the rquirements of our prject is that we need to send broadcast messages to everyone in the list. Normal messages and replies work fin, but when i snd a broadcast message, i get this service unavailable error 503 message. There are about 1000 user in my contact list. Is this some bug in the code or is it google policy to prevent rapid messaging. Also, how do other google bots cater to a large contact base ? does google provide a commercial solution for such applications ? Thanks

  • Java 7 New Features

    - by John W.
    I have done some good reading on the new java.util.concurrent features being introduced with the java 7 release. For instance, Phaser, TransferQueue and the more exciting Fork Join Framework. I recently saw a power point made by Josh Bloch about even more features that are going to be introduced however that link has been lost. For example I remember one change is being able to build a Map the same way you can build an array for: Map myMap = {"1,Dog","2,Cat"}; and so forth (this may not be 100% correct but the idea is there) Does anyone know of a list or just can name some new things to look forward to? Note: I did see a question asked http://stackoverflow.com/questions/213958/new-features-in-java-7 however it was asked ~2 years ago and I am sure the list of updates are more concrete. Thanks!

  • Does "opening a file" mean loading it completely into memory?

    - by mystify
    There's an AudioFileOpenURL function which opens an file. With AudioFileReadPackets that file is accessed to read packets. But one thing that stucks in my brain is: Does AudioFileOpenURL actually load the whole monster into memory? Or is that a lightweight operation? So is it possible to read data from a file, only a specific portion, without having the whole terabytes of stuff in memory?

  • Best real "computer crime"?

    - by c0m4
    Are there any real stories about computer crime? I'm talking about stuff like in "Office Space", stealing fractions of pennies a couple of million times... Like that, only actual events. And not Captain Crunch, please, making phone calls for free does not count. No, actual robberies or super smart frauds that depended on computer technology to some extent. Links or books for further reading please.

  • How can I inherit form and access controls from mother form?

    - by kasia
    Hi, I'm in the middle of writing my project and I have this problem: I try to write a library and I want to use it in my application. In library I have a form with menu strip, tool bar, list view, tree view and etc. Everything in library is protected. In my application I have created the form which inherit form the library. I can change and add new functionality to list view and tree view using designer panel in VS 2008 but I don't have access to menu strip and tool bar, even though they are protected. Why is that so? I will be thankful for some advice.

  • Rails 3 Order By Count on has_many :through

    - by goo
    I have an application where I can list Items and add tags to each Item. The models Items and Tags are associated like this: class Item < ActiveRecord::Base has_many :taggings has_many :tags, :through => :taggings end class Tagging < ActiveRecord::Base belongs_to :item belongs_to :tag end class Tag < ActiveRecord::Base has_many :taggings has_many :items, :through => :taggings end So, this many-to-many relationship allows me to set n tags for each Item, and the same tag can be used several times. I'd like to list all tags ordered by the number of items associated with this tag. More used tags, shows first. Less used, last. How can I do that? Regards.

  • Problem with DataGrid_CellFormatting event to set default value

    - by Royson
    Hi, I have created an applicationto display list of files. it also provide user interface for adding new column to a gridview. DataGridViewTextBoxColumn txtBoxColumn = new DataGridViewTextBoxColumn(); txtBoxColumn.Name = columnName; txtBoxColumn.HeaderText = columnName; g_dataGridView.Columns.Add(txtBoxColumn); User will create some custom type column therefore i am adding column directly to grid. I am also able to set its default value before adding for this i am using DataGrid_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e) { if (colIndexWithDefaultValue.Count > 0) { if (colIndexWithDefaultValue.Contains(e.ColumnIndex)) { g_dataGridView.Rows[e.RowIndex].Cells[e.ColumnIndex].Value = colIndexWithDefaultValue[e.ColumnIndex]; } } } where colIndexWithDefaultValue is list of columns with its default value. It is able to show newly created column with default value. But values are getting set for currently visible rows. To set value for all rows i have to do scrolling. So, how do i overcome this problem...

    - by Grzenio
    Hi, In my ant script, which runs the end-to-end integration tests, I first start a process, then do some other stuff, then run the tests, and then I need to make sure I kill the process. However, I need to make sure I kill the process even if something fails (so I need an equivalent to try finally). What is the recommended way of doing it?

  • How to avoid escaping by accident in PERL using system()?

    - by Brian
    I want to run some commands using the system() command, I do this way: execute_command_error("trash-put '/home/$filename'"); Where execute_command_error will report if there was an error with whatever system command it ran. I know I could just unlink the file using Perl commands, but I want to delete stuff using trash-put as it's a type of recycling program. My problem is that $filename will sometimes have apostrophes, quotes, and other weird characters in it that mess up the system command or Perl itself.

  • Script-Based Configuration in .net?

    - by Michael Stum
    One of the downsides of web.config/app.config is that it's just Magic Strings everywhere, since it's just an XML file. Interpreted languages like PHP or Ruby have the advantage that the configuration is just code that is executed. In .net, doing stuff in code requires a redeployment, which defeats the purpose. Now, before I build my own web.config replacement based on Boo or PowerShell I wanted to know if there is an existing one?

  • How can I sort an array, yet exclude certain elements (to be kept at the same position in the array)

    - by calumbrodie
    This will be implemented in Javascript (jQuery) but I suppose the method could be used in any language. I have an array of items and I need to perform a sort. However there are some items in the array that have to be kept in the same position (same index). The array in question is build from a list of <li> elements and I'm using .data() values attached to the list item as the value on which to sort. What approach would be best here? <ul id="fruit"> <li class="stay">bananas</li> <li>oranges</li> <li>pears</li> <li>apples</li> <li class="stay">grapes</li> <li>pineapples</li> </ul> <script type="text/javascript"> var sugarcontent = new Array('32','21','11','45','8','99'); $('#fruit li').each(function(i,e){ $(this).data(sugarcontent[i]); }) </script> I want the list sorted with the following result... <ul id="fruit"> <li class="stay">bananas</li> <!-- score = 32 --> <li>pineapples</li> <!-- score = 99 --> <li>apples</li> <!-- score = 45 --> <li>oranges</li> <!-- score = 21 --> <li class="stay">grapes</li> <!-- score = 8 --> <li>pears</li> <!-- score = 11 --> </ul> Thanks!

  • IE7 and IE8: Float clearing without adding empty elements

    - by tk-421
    Hello, I'm having a problem similar to the one described here (without a resolution): http://stackoverflow.com/questions/2467745/ie7-float-and-clear-on-the-same-element The following HTML renders as intended in Firefox but not in (both) IE7 and IE8: <html> <head> <style> ul { list-style-type: none; } li { clear: both; padding: 5px; } .left { clear: left; float: left; } .middle { clear: none; float: left; } .right { clear: right; float: left; } </style> </head> <body> <ul> <li>1</li> <li class="left">2</li> <li class="right">3</li> <li class="left">4</li> <li class="middle">5</li> <li class="right">6</li> <li>7</li> </ul> </body> </html> This is a form layout, and in Firefox the results appear like: 1 2 3 4 5 6 7 That's what I'm going for. In IE7 and IE8 however, the results are: 1 2 3 5 6 4 7 [Note: I don't want to float anything to the right because I want the fields on my form to left-align correctly, without a giant space in-between the floated fields to account for the parent container's width.] Apparently I need a full clear, and can probably add an empty list-item element to the list to force clearing, but that seems like a dumb solution and sort of defeats the purpose. Any ideas? I've spent a few hours reading and trying different options without success.

  • jQuery on/delegate correct syntax

    - by KryptoniteDove
    As the jQuery API is currently down, is anyone able to assist me with the below? I am ajax loading an unordered list into the web page and need to be able to attach hover and click events to the list items. <ul> <li class="option">Item 1</li> <li class="option">Item 1</li> <li class="option">Item 1</li> </ul> So far I have tried a few variations of the below jQuery code using .on for version 1.7+ $("ul").on("click", "li .option", function(){ alert($(this).text()); }); Can anyone point me in the right direction? I'm aware that .live has been depreciated and that .delegate has been superceeded so really only looking for a solution that will allow me to use .on. Thanks as always!

  • Assign grid.arrange to object

    - by Tyler Rinker
    I want to arrange plots with grid.arrange to make more complex coplots and then use grid.arrange to combine these complex coplots. I am using the following solution (http://stackoverflow.com/a/13295880/1000343) in this task to arrange mutliple plots and ensure they have equal widths. Here is a demo of the code: library(ggplot2); library(gridExtra) gA <- ggplotGrob(A) gB <- ggplotGrob(B) maxWidth = grid::unit.pmax(gA$widths[2:5], gB$widths[2:5]) gA$widths[2:5] <- as.list(maxWidth) gB$widths[2:5] <- as.list(maxWidth) x <- grid.arrange(gA, gB, ncol=1) y <- grid.arrange(gA, gB, ncol=1) grid.arrange(x, y, ncol=2) To be clear in my case x and y are slightly different plots with different values. I know grid.arrange isn't returning the plot as other grid based functions.
