• Mongo Map Reduce first time

  - by James

  Hello guys, First time Map/Reduce user here, and using MongoDB. I have a lot of page visit data which I'd like to make some sense of by using Map/Reduce. Below is basically what I want to do, but as a total beginner a Map/Reduce, I think this is above my knowledge! Find all visits to current page where external = true within the last 30 days (unix timestamp, I deal with the date ranges in PHP and then the array, not mongo date) Group all visits by referral location For each referral location, calculate how many then went to visit a page which has a certain word in the [tags]. I'm using the normal Mongo PHP extension if that has an impact.

• PHP File Upload second file does not upload, first file does without error

  - by Curtis

  So I have a script I have been using and it generally works well with multiple files... When I upload a very large file in a multiple file upload, only the first file is uploaded. I am not seeing an errors as to why. I figure this is related to a timeout setting but can not figure it out - Any ideas? I have foloowing set in my htaccess file php_value post_max_size 1024M php_value upload_max_filesize 1024M php_value memory_limit 600M php_value output_buffering on php_value max_execution_time 259200 php_value max_input_time 259200 php_value session.cookie_lifetime 0 php_value session.gc_maxlifetime 259200 php_value default_socket_timeout 259200

• Driving me INSANE: Unable to Retrieve Metadata for

  - by Loren

  I've been spending the past 3 days trying to fix this problem I'm encountering - it's driving me insane... I'm not quite sure what is causing this bug - here are the details: MVC4 + Entity Framework 4.4 + MySql + POCO/Code First I'm setting up the above configuration .. here are my classes: namespace BTD.DataContext { public class BTDContext : DbContext { public BTDContext() : base("name=BTDContext") { } protected override void OnModelCreating(DbModelBuilder modelBuilder) { base.OnModelCreating(modelBuilder); //modelBuilder.Conventions.Remove<System.Data.Entity.Infrastructure.IncludeMetadataConvention>(); } public DbSet<Product> Products { get; set; } public DbSet<ProductImage> ProductImages { get; set; } } } namespace BTD.Data { [Table("Product")] public class Product { [Key] public long ProductId { get; set; } [DisplayName("Manufacturer")] public int? ManufacturerId { get; set; } [Required] [StringLength(150)] public string Name { get; set; } [Required] [DataType(DataType.MultilineText)] public string Description { get; set; } [Required] [StringLength(120)] public string URL { get; set; } [Required] [StringLength(75)] [DisplayName("Meta Title")] public string MetaTitle { get; set; } [DataType(DataType.MultilineText)] [DisplayName("Meta Description")] public string MetaDescription { get; set; } [Required] [StringLength(25)] public string Status { get; set; } [DisplayName("Create Date/Time")] public DateTime CreateDateTime { get; set; } [DisplayName("Edit Date/Time")] public DateTime EditDateTime { get; set; } } [Table("ProductImage")] public class ProductImage { [Key] public long ProductImageId { get; set; } public long ProductId { get; set; } public long? ProductVariantId { get; set; } [Required] public byte[] Image { get; set; } public bool PrimaryImage { get; set; } public DateTime CreateDateTime { get; set; } public DateTime EditDateTime { get; set; } } } Here is my web.config setup... <connectionStrings> <add name="BTDContext" connectionString="Server=localhost;Port=3306;Database=btd;User Id=root;Password=mypassword;" providerName="MySql.Data.MySqlClient" /> </connectionStrings> The database AND tables already exist... I'm still pretty new with mvc but was using this tutorial The application builds fine.. however when I try to add a controller using Product (BTD.Data) as my model class and BTDContext (BTD.DataContext) as my data context class I receive the following error: Unable to retrieve metadata for BTD.Data.Product using the same DbCompiledModel to create context against different types of database servers is not supported. Instead, create a separate DbCompiledModel for each type of server being used. I am at a complete loss - I've scoured google with almost every different variation of that error message above I can think of but to no avail. Here are the things i can verify... MySql is working properly I'm using MySql Connector version 6.5.4 and have created other ASP.net web forms + entity framework applications with ZERO problems I have also tried including/removing this in my web.config: <system.data> <DbProviderFactories> <remove invariant="MySql.Data.MySqlClient"/> <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.5.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" /> </DbProviderFactories> I've literally been working on this bug for days - I'm to the point now that I would be willing to pay someone to solve it.. no joke... I'd really love to use MVC 4 and Razor - I was so excited to get started on this, but now i'm pretty discouraged - I truly appreciate any help/guidance on this! Also note - i'm using Entityframework from Nuget... Another Note I was using the default visual studio template that creates your MVC project with the account pages and other stuff. I JUST removed all references to the added files because they were trying to use the "DefaultConnection" which didn't exist - so i thought those files may be what was causing the error - however still no luck after removing them - I just wanted to let everyone know i'm using the visual studio MVC project template which pre-creates a bunch of files. I will be trying to recreate this all from a blank MVC project which doesn't have those files - i will update this once i test that Other References It appears someone else is having the same issues I am - the only difference is they are using sql server - I tried tweaking all my code to follow the suggestions on this stackoverflow question/answer here but still to no avail

• Finding first alphabetic character in a DB2 database field

  - by Paul Alan Taylor

  I'm doing a bit of work which requires me to truncate DB2 character-based fields. Essentially, I need to discard all text which is found at or after the first alphabetic character. e.g. 102048994BLAHBLAHBLAH becomes:- 102048994 In SQL Server, this would be a doddle - PATINDEX would swoop in and save the day. Much celebration would ensue. My problem is that I need to do this in DB2. Worse, the result needs to be used in a join query, also in DB2. I can't find an easy way to do this. Is there a PATINDEX equivalent in DB2? Is there another way to solve this problem? If need be, I'll hardcode 26 chained LOCATE functions to get my result, but if there is a better way, I am all ears.

• Use sed to replace first 8 and last 4 pipes on every line in a file

  - by Dan Watling

  Here's the situation, I have a text file that is pipe-delimited and one of fields contains pipe characters. I already have a sed script that will change it to be tab-delimited, but the problem is it's terribly slow. It will replace the first occurrence of a pipe 8 times, then replace the last occurrence of a pipe 4 times. I'm hoping there's a quicker way to do what I need. Any thoughts would be appreciated. Here's my current sed script: sed 's/|\(.*\)/\t/;s/|\(.*\)/\t/;s/|\(.*\)/\t/;s/|\(.*\)/\t/;s/|\(.*\)/\t/;s/|\(.*\)/\t/;s/|\(.*\)/\t/;s/|\(.*\)/\t/;s/|\(.*\)/\t/;s/\(.*\)|/\t/;s/\(.*\)|/\t/;s/\(.*\)|/\t/;s/\(.*\)|/\t/' $1 > $1.tab Thanks, -Dan

• Asp.net text box is only returning the first value

  - by queryne

  C sharp newbie question...I have a simple asp.net form that has a textbox that collects phonenumbers to send SMS messages. If I bypass the form and hardcode the numbers using the following format: "2133211234",#1233211234" the code works fine. However when i try to use this same format using my form, the sms will ONLY send to the first number. I have a feeling i'm missing out on some property on my form that will accept all of the values. also any idea how how i can add some lines of code that will allow users to enter numbers like this: 3123211234,4123212344 and have it converted to the format above when the number is submitted? Any ideas? Thanks in advance.

• EF4, MVC 3, Azure and Code First or Traditional

  - by RichardAlanA

  I am planning to build a web application using ASP MVC3 that runs on Azure with a SQL Azure back end. I would like to use the Microsoft stack and have no plans to ever change to another stack. I am looking into the use of WCF and WF but that would be in the future. I looked at the traditional and Code First approach to using Entity Framework but I can't see if there is any advantage in using one or the other approach. Sure they each have advantages but for me I don't care if my classes do inherit from EF classes. All I want is to find the most efficient solution. Can anyone out there give me some advice as to which approach might be the best. thanks very much Richard

• Regex to match the first file in a rar archive file set in Python

  - by mridang

  I need to uncompress all the files in a directory and for this I need to find the first file in the set. I'm currently doing this using a bunch of if statements and loops. Can i do this this using regex? Here's a list of files that i need to match: yes.rar yes.part1.rar yes.part01.rar yes.part001.rar yes.r01 yes.r001 These should NOT be matched: no.part2.rar no.part02.rar no.part002.rar no.part011.rar no.r002 no.r02 I found a similar regex on this thread but it seems that Python doesn't support varible length lookarounds. A single line regex would be complicated but I'll document it well and it's not a problem. It's just one of those problems you beat your heap up, over. Thanks in advance guys. :)

• ASP.net - First build fails with 'Unknown server tag'

  - by Sophia

  I have multiple custom controls used on a ASPX (and C#) page registered from within the page rather than in Web.Config. On the first build (or rebuild), build fails with error messages for wherever I've used the custom controls. Subsequent builds are successful. The error message: Unknown server tag 'prefix:ExampleControl'. What might cause this, and how can I fix it? Register syntax: <%@ Register Src="ControlsFolder/ExampleControl.ascx" TagName="ExampleControl" TagPrefix="prefix" %> <!-- etc --> Usage syntax: <prefix:ExampleControl runat="server" ID="ExampleControl1" /> <!-- etc -->

• Python "draw() must be called with Label instance as first argument (got _WindowMetaclass instance i

  - by Amorack

  This is a class I made using Python with pyglet to display a window. class Window(pyglet.window.Window): def __init__(self): super(Window, self).__init__() pyglet.text.Label("Prototype") windowText = text.Label.draw(Window, "Hello World", font_name = "Times New Roman", font_size = 36, color = (193, 205, 193, 255)) def on_draw(self): self.clear() self.label.draw() Every time I try to run it I get the error "TypeError: unbound method draw() must be called with Label instance as first argument (got _WindowMetaclass instance instead)". I'm pretty sure I know what I have to do (find how to get Label's instance) just not how to do it. Could someone help me understand how to make this work?

• ComboBox.SelectionChanged doesn't catch the first selection

  - by trnTash

  I need to fill textboxes depending on the item selected in a combobox. I fill combo async and in Completed event I have the following code combo.ItemsSource = e.Result; combo.DisplayMemberPath = "Name"; combo.SelectedIndex = -1; Then in the SelectionChanged event of the combo, I catch the selected object MyClass mc= ((ComboBox)sender).SelectedItem as MyClass; tbxName.Text = mc.Name; ... However, when I load the project and select any event for the 1st time, NOTHING happens. Every other time (2nd, 3rd, nth) the data is correctly caught and displayed. So I need to know why the combo doesn't catch the first selection? That's the reason I have the code combo.SelectedIndex = -1 (when the app loads, combo is empty - selection -1 works).

• Cannot format first column in WxPython's ListCtrl

  - by Matt Clarke

  If I set the format of the first column in a ListCtrl to align centre (or align right) nothing happens. It works for the other columns. This only happens on Windows - I have tested it on Linux and it works fine. Does anyone know if there is a work-round or other solution? Here is an example based on code found at http://zetcode.com/wxpython/ import wx import sys packages = [('jessica alba', 'pomona', '1981'), ('sigourney weaver', 'new york', '1949'), ('angelina jolie', 'los angeles', '1975'), ('natalie portman', 'jerusalem', '1981'), ('rachel weiss', 'london', '1971'), ('scarlett johansson', 'new york', '1984' )] class Actresses(wx.Frame): def __init__(self, parent, id, title): wx.Frame.__init__(self, parent, id, title, size=(380, 230)) hbox = wx.BoxSizer(wx.HORIZONTAL) panel = wx.Panel(self, -1) self.list = wx.ListCtrl(panel, -1, style=wx.LC_REPORT) self.list.InsertColumn(0, 'name', wx.LIST_FORMAT_CENTRE,width=140) self.list.InsertColumn(1, 'place', wx.LIST_FORMAT_CENTRE,width=130) self.list.InsertColumn(2, 'year', wx.LIST_FORMAT_CENTRE, 90) for i in packages: index = self.list.InsertStringItem(sys.maxint, i[0]) self.list.SetStringItem(index, 1, i[1]) self.list.SetStringItem(index, 2, i[2]) hbox.Add(self.list, 1, wx.EXPAND) panel.SetSizer(hbox) self.Centre() self.Show(True) app = wx.App() Actresses(None, -1, 'actresses') app.MainLoop()

• Objective C: Create arrays from first array based on value

  - by Nic Hubbard

  I have an array of strings that are comma separated such as: Steve Jobs,12,CA Fake Name,21,CA Test Name,22,CA Bill Gates,44,WA Bill Nye,21,OR I have those values in an NSScanner object so that I can loop through the values and get each comma seperated value using objectAtIndex. So, what I would like to do, is group the array items into new arrays, based on a value, in this case, State. So, from those, I need to loop through, checking which state they are in, and push those into a new array, one array per state. CA Array: Steve Jobs,12,CA Fake Name,21,CA Test Name,22,CA WA Array: Bill Gates,44,WA OR Array: Bill Nye,21,OR So in the end, I would have 3 new arrays, one for each state. Also, if there were additional states used in the first array, those should have new arrays created also. Any help would be appreciated!

• Making selectable again a WPF TreeviewITem after the first click

  - by pileggi

  Hi, I have a TreeVIew WPF with 2 Levels of Data. I have deleted the ToogleButton from the TreeViewItemTemplate. Now I'd like to expand / collapse the groups with a single mouse-click (not with a double click as the default behaviour). I have tried in this way: Private Sub tvArt_SelectedItemChanged(ByVal sender As System.Object, _ ByVal e As RoutedPropertyChangedEventArgs(Of System.Object)) Handles tvArt.SelectedItemChanged If e.NewValue Is Nothing = False Then Dim ri As P_RicambiItem = TryCast(e.NewValue, P_RicambiItem) If ri Is Nothing = False Then If ri.isExpanded Then ri.isExpanded = False Else ri.isExpanded = True End If ri.isSelected = False End If End If End Sub Using my properties "isExpanded" and "isSelected" in the collection data source. But it works only halfway: after the first click, infact, I can't click for a second time on the same item, because, even if I've deselected it, the event handler "remembers" that it was the last selected item and it doesn't capture the event "SelectedItemChanged". How can I do? Thanks a lot, Pileggi

• Help with a pseudo-class, first-child

  - by zac

  I am working on a CMS platform with limited access to the template files and want to try and control some of the layout with pseudo class but no luck yet. Can anyone see what is wrong with this structure and why my pseudo class is being ignored? <div id="main"> <div class="someRandomDiv"></div> <div class="block"> stuff </div> <div class="block"> more stuff </div> </div> and i am trying something like this #main .block {border: 1px solid blue} #main .block:first-child {border: 1px solid red} so with this example I would think the stuff block would have a red border and more stuff would have a blue but it is all just blue. Thanks for any help with this.

• Regex only retrieves the first necessary element but not all of them

  - by Serge

  Can anybody help me with retrieving some elements from the following example text: sdfaasdflj asdfjl;a AB-12/34 BC-/85 CD-//8 DD-77 DE-78/9 EE-78-98 asdf; asdjf It is necessary to get the following elements: AB-12/34, BC-/85, CD-//8, DD-77, DE-78/9 When I'm using a regular expression like this: \s*(?<elements>\b[A-Z]{2}-[/0-9]+\b) everything works fine - all the necessary elements are being retrieved (except for the EE element are amonth them, but it doesn't matter). The problem is that this line is a part of a more complex regex, so when I'm trying to apply a regex like this: (?s).*\sas.*? \s*(?<elements>\b[A-Z]{2}-[/0-9]+\b)*.* .*as It only returns me just the first AB-12/34 element and nothing else. How to correct the regex to get all the elements? TIA.

• Remove first 'n' elements from list without itterating

  - by Eldhose M Babu

  I need an efficient way of removing items from list. If some condition happens, I need to remove first 'n' elements from a list. Can some one suggest the best way to do this? Please keep in mind: performance is a factor for me, so I need a faster way than itterating. Thanks. I'm thinking of a way through which the 'n'th item can be made as the starting of the list so that the 0-n items will get garbage collected. Is it possible?

• Facebook Javascript SDK: First time logging in

  - by Brandon

  I'm currently integrating Facebook with my website using the Javascript SDK. I've got the login portion working well. The only thing I'm trying to figure out is if there is a way to tell if it was the first time the user logged into my website using their Facebook credientials. I tried subscribing to auth.login, but that didn't seem to have any information about that. Is there a flag anywhere that lets me know this? Or another way to go about looking this up? I realize I could do some server side code, but I'd prefer to stay away from that if possible. Thanks in advance, Brandon

• JQuery Autocomplete only suggesting first row

  - by Chris McCall

  I'm doing research using JQuery's Autocomplete plugin and Google Maps' API. What I have so far is located here. I'm using Asp.net MVC to generate the list of potential address matches (limited to US addresses only) and presenting them as a pipe-delimeted list to Autocomplete, which is supposed to be .spliting them up and suggesting them to the user. The problem I'm having (besides a stubborn IE-only javascript error, which I'll break into another question), is that only the first result is suggested. This page clearly shows two results, yet typing "3118" into the textbox produces only the Galax Dr result. How can I get Automplete to produce both results?

• Slide in the second tab bar view by clicking on item in the first

  - by Henrik Erlandsson

  I have an app with three tabs that switch views instantaneously when the user taps them. The first view is a table view selecting which 'location type' to filter by, to only show those pins (add those annotations) to the second view, a MapView. When a table cell is clicked, it switches instantaneously to the mapview, using this code: self.tabBarController.selectedIndex=1; However, I would like to do this with a slide-in-from-right animation, like the one you get when drilling down a hierarchy of table views. I tried this: [self.navigationController pushViewController:[self.tabBarController.viewControllers objectAtIndex:1] animated:YES]; which compiles without error or warning, but does not switch views. How do I 'apply' a navigation controller 'onto' a tab bar controller? Or is there some way to select another viewcontroller and specify an animation?

• UIView animation doesn't work first time

  - by BobC

  Hello everybody, I have a seachButton in the navigation bar which upon hitting calls following method: - (IBAction)search:(id)sender { if (nil == searchViewController) searchViewController = [[SearchViewController alloc] initWithNibName:@"SearchViewController" bundle:nil]; searchViewController.view.backgroundColor = [UIColor clearColor]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:1.0]; [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:searchViewController.view cache:NO]; [self.view addSubview:searchViewController.view]; [UIView commitAnimations]; } It should load SearchViewController.xib which contains a view with UISearchBar and two buttons. When I call the search method for the first time, the view appears very quickly with some weird animation, when I call it again, the animation is alright. Does anyone have a clue what could be wrong?
