  • Combining multiple rows into one row, Oracle

    - by Torbjørn
    Hi. I'm working with a database which is created in Oracle and used in a GIS-software through SDE. One of my colleuges is going to make some statistics out of this database and I'm not capable of finding a reasonable SQL-query for getting the data. I have two tables, one with registrations and one with registrationdetails. It's a one to many relationship, so the registration can have one or more details connected to it (no maximum number). table: Registration RegistrationID Date TotLenght 1 01.01.2010 5 2 01.02.2010 15 3 05.02.2009 10 2.table: RegistrationDetail DetailID RegistrationID Owner Type Distance 1 1 TD UB 1,5 2 1 AB US 2 3 1 TD UQ 4 4 2 AB UQ 13 5 2 AB UR 13,1 6 3 TD US 5 I want the resulting selection to be something like this: RegistrationID Date TotLenght DetailID RegistrationID Owner Type Distance DetailID RegistrationID Owner Type Distance DetailID RegistrationID Owner Type Distance 1 01.01.2010 5 1 1 TD UB 1,5 2 1 AB US 2 3 1 TD UQ 4 2 01.02.2010 15 4 2 AB UQ 13 5 2 AB UR 13,1 3 05.02.2009 10 6 3 TD US 5 With a normal join I get one row per each registration and detail. Can anyone help me with this? I don't have administrator-rights for the database, so I can't create any tables or variables. If it's possible, I could copy the tables into Access.

  • Check for default value of attribute in XPath

    - by iref
    Hi, i have XML schema: <xsd:complexType name="contactsType"> <xsd:sequence> <xsd:element name="contact" type="contactType" minOccurs="0" maxOccurs="unbounded"/> </xsd:sequence> <xsd:attribute name="visible" type="xsd:boolean" default="true"/> </xsd:complexType> and i want to find all contacts which have @visible=true, //contacts[@visible='true'] but this expression doesn' t return nodes without set @visible like this: <contacts /> so i want to know if there is any function in XPath which returns also default values of attributes Thanks Jan

  • ASP.Net Web Forms LoginStatus Multiple LoginURL - suggestions?

    - by TGuimond
    Hi Guys, I am developing a multi-lingual website. I am determining the requested language via a querystring variable eg: http://mydomain.com/default.aspx?lang=en I am using two <asp:LoginStatus /> controls in my masterpage. My web.config file is set up like this for forms authentication. <authentication mode="Forms"> <forms loginUrl="~/login.aspx" protection="All" timeout="30" name=".ASPXAUTH" path="/" requireSSL="false" slidingExpiration="true" defaultUrl="default.aspx" cookieless="UseDeviceProfile" enableCrossAppRedirects="false"/> </authentication> Currently when you click on a <asp:LoginStatus /> you will be redirected to my login page and the url will look something like this: http://mydomain.com/login.aspx?ReturnUrl=%2fdefault.aspx%3flang%3den What solutions are available to me so that I can append my lang variable to my login.aspx? depending on which language is currently active?

  • "Downloading" a computed value form JavaScript

    - by Travis Jensen
    I'm hoping you can prove me wrong here (please, please, please! ;). I have a situation where I need to download encrypted data from a Server D (for "Data"). Server K (for "Key") has the encryption key. For security sake, I would really prefer that Server D never know the key that Server K knows. What I want is my client (e.g. your browser) to connect to Server D for the data and Server K for the key and doe the decryption locally so the unencrypted stuff never leaves your computer. I can do this fine for text areas in the dom by replacing the contents of the HTML. However, sometimes, I would like to do larger files that I stream to the file system. For instance, perhaps I want to encrypt a movie and decrypt it and stream the contents to the my video player. I am not a JavaScript guru by any stretch, especially when it comes to the edge cases of things like the security sandbox. For Small D, I can handle the decryption, but I don't know how to save the decrypted file. Large D seems problematic as memory runs out. Anybody have any ideas that don't involve native plugins? Thanks!

  • Multiple actions upon a case statement in Haskell

    - by Schroedinger
    One last question for the evening, I'm building the main input function of my Haskell program and I have to check for the args that are brought in so I use args <- getArgs case length args of 0 -> putStrLn "No Arguments, exiting" otherwise -> { other methods here} Is there an intelligent way of setting up other methods, or is it in my best interest to write a function that the other case is thrown to within the main? Or is there an even better solution to the issue of cases. I've just got to take in one name.

  • Good programming style when handling multiple objects

    - by Glitch
    I've been programming a software version of a board game. Thus far I have written the classes which will correspond to physical objects on the game board. I'm well into writing the program logic, however I've found that many of the logic classes require access to the same objects. At first I was passing the appropriate objects to methods as they were called, but this was getting very tedious, particularly when the methods required many objects to perform their tasks. To solve this, I created a class which initialises and stores all the objects I need. This allows me to access an object from any class by calling Assets.dice(), for example. But now that I've thought about it, this doesn't seem right. This is why I'm here, I fear that I've created some sort of god class. Is this fear unfounded, or have I created a recipe for disaster?

The header is followed by a number of dashes. My issue is that, in the data, you see a number of entries where the cease time is NULL i.e event is still active. All such entries must go i.e for each element where the alarm cease time is NULL, the start time, the cease time(in this case NULL) and the actual element must be deleted from the file. In the remaining data, all the text starting from word SubNetwork upto BtsSiteMgr= must also go. Along with the headers and the dashes. Final output should look like below: Apr 5 2010 5:55PM Apr 5 2010 6:43PM LUGALAMBO_900 Apr 5 2010 5:58PM Apr 5 2010 6:01PM BULAGA Apr 5 2010 6:03PM Apr 5 2010 6:04PM KAPKWAI_900 Apr 5 2010 6:03PM Apr 5 2010 6:03PM BULAGA Apr 5 2010 6:03PM Apr 5 2010 7:01PM BULAGA Below is a Perl script that I have written. It has taken care of the headers, the dashes, the NULL entries but I have failed to delete the lines following the NULL entries so as to produce the above output. #!/usr/bin/perl use strict; use warnings; $^I=".bak" #Backup the file before messing it up. open (DATAIN,"<george_perl.txt")|| die("can't open datafile: $!"); # Read in the data open (DATAOUT,">gen_results.txt")|| die("can't open datafile: $!"); #Prepare for the writing while (<DATAIN>) { s/Event_time//g; s/Cease_time//g; s/Object_of_reference//g; s/\-//g; #Preceding 4 statements are for cleaning out the headers my $theline=$_; if ($theline =~ /NULL/){ next; next if $theline =~ /SubN/; } else{ print DATAOUT $theline; } } close DATAIN; close DATAOUT; Kindly help point out any modifications I need to make on the script to make it produce the necessary output. Will be very glad for your help Kind regards George.

  • How to handle multiple delegates

    - by mac_55
    I've got a view in my app that does pretty much everything, and I like it that way. The problem however is that it's implementing 5 or 6 different delegates, which seems a little bit messy. My question is, does the view controller have to implement all of the delegates? or is there some way I can separate the code out into different files (without having to do a major restructure or rewrite)? Here's all the delegates I'm implementing: @interface MyView : UIViewController <UIScrollViewDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate, UIActionSheetDelegate, MFMailComposeViewControllerDelegate>

  • PHP photo gallery with multiple upload form

    - by NightMICU
    Hi everyone, I am trying to develop a PHP driven gallery with a form that has at least four file upload boxes, each with its own title and caption. I have been using php.upload.class to process uploaded photos but not sure how I would go about handling each individual upload while preserving its details (title, caption). Is there a practical way to do this or should I instead upload just the photos and then have the user add titles and captions on the next page? Any help/suggestion would be greatly appreciated. Thanks!

  • Creating an SQL variable character column > 255 characters supporting multiple databases

    - by Piers
    I have an application that stores data through an ODBC data source of the user's choosing. So far it has worked well on a range of database systems (e.g. JET, Oracle, SQL Server), as the SQL syntax is fairly simple. Now I am running into a problem where I need to store more than 255 characters in my strings. Previously I created the table using column type VARCHAR (255). Now if I try to create a table using, e.g. VARCHAR (512) then it falls over on Access databases. I know that I can use the MEMO type for Access, but this is non-standard SQL and will thus likely fail on other database systems (e.g. Oracle). Is there any widely supported SQL standard for creating text columns wider than 255 characters, or do I need to find another solution? The alternatives seem to me to be: 1) Profile the database system and customise the SQL CREATE TABLE command based on the database system. I don't like this as it defeats the purpose of using ODBC. 2) Add extra columns of 255 chars as required (e.g. LONGSTRING1, LONGSTRING2, ...) and concatenate after reading. I don't like this because it means the number of columns can vary between tables and it complicates read/write. Are there any other viable alternatives to these two options? Or is it possible to have an SQL compliant CREATE TABLE command supported by the majority of database vendors, that supports strings longer than 255 chars?

  • Multiple Service Address Configs in WCF Silverlight App

    - by CraigS
    My team is building our first significant Silverlight application, using a 3 layered architecture and WCF. We have developed about 10 separate WCF services in the middle layer so far, and this number is only going to grow. Generally, the presentation layer (ie. the Silverlight app) is pointing to the services as hosted on our dev server. However, there are times when I want it to access the services from localhost - ie. the developers machine. Is there an easy way to change where the presentation layer is looking for the services? Is there some way of easily switching between options here?

  • Determine which mouse was clicked (multiple mice devices) in .NET

    - by Morten K
    Hi, I want to detect when my touchpad is clicked! I normally use a usb mouse, so I don't use the touchpad for anything. Instead I'd like to make it possible to perform an action in .NET, when the touchpad is clicked. This way I can use it as a shortcut: One tap and something cool happens. Is this possible, and if yes, any clue how? I'd prefer if it could be working in VB.NET or C#. My theory is that I'd have to make a mousehook, which then somehow determines which device the click is coming from. If the click is determined to be from the touchpad, then cancel the click and doWhatever(). Thanks!

  • Playing Multiple Sounds at Once in Qt

    - by Ben
    I'm trying to play background music along with sound effects using Qt. However, I can't get more than one sound to play at once. For example: QSound::play("Music.wav"); QSound::play("Effect.wav"); When this code is run (on Windows), you can hear Music.wav just start to play, but then it stops and Effect.wav plays. Is there any way to get the two sounds to play at once?

  • Ajax, Multiple Attachments and Paperclip question.

    - by dustmoo
    Alright everyone this is a bit of a complicated setup so if I need to clarify the question just let me know. I have a model: class IconSet < ActiveRecord::Base has_many :icon_graphics end This Model has many icongraphics: class IconGraphic < ActiveRecord::Base belongs_to :icon_set has_attached_file :icon has_attached_file :flagged end As you can see, IconGraphic has two attached files, basically two different versions of the icon that I want to load. Now, this setup is working okay if I edit the icongraphic's individually, however, for ease of use, I have all the icon graphics editable under the IconSet. When you edit the icon set the form loads a partial for the icongraphics: <% form_for @icon_set, :html => {:class => 'nice', :multipart => true} do |f| %> <fieldset> <%= f.error_messages %> <p> <%= f.label :name %> <%= f.text_field :name, :class => "text_input" %> </p> <!-- Loaded Partial for icongraphics --> <div id="icon_graphics"> <%= render :partial => 'icon_graphic', :collection => @icon_set.icon_graphics %> </div> <div class="add_link"> <%= link_to_function "Add an Icon" do |page| page.insert_html :bottom, :icon_graphics, :partial => 'icon_graphic', :object => IconGraphic.new end %> </div> <p><%= f.submit "Submit" %></p> </fieldset> <% end %> This is based largely off of Ryan's Complex Forms Railscast. The partial loads the file_field forms: <div class="icon_graphic"> <% fields_for "icon_set[icon_graphic_attributes][]", icon_graphic do |icon_form|-%> <%- if icon_graphic.new_record? -%> <strong>Upload Icon: </strong><%= icon_form.file_field :icon, :index => nil %><br/> <strong>Upload Flagged Icon: </strong><%= icon_form.file_field :flagged, :index => nil %> <%= link_to_function image_tag('remove_16.png'), "this.up('.icon_graphic').remove()"%><br/> <% else -%> <%= image_tag icon_graphic.icon.url %><br/> <strong>Replace <%= icon_graphic.icon_file_name %>: </strong><%= icon_form.file_field :icon, :index => nil %><br /> <% if icon_graphic.flagged_file_name.blank? -%> <strong>Upload Flagged Icon: </strong><%= icon_form.file_field :flagged, :index => nil %> <% else -%> <strong>Replace <%= icon_graphic.flagged_file_name %>: </strong><%= icon_form.file_field :flagged, :index => nil %> <%= icon_form.hidden_field :flagged, :index => nil %> <% end -%> <%= link_to_function image_tag('remove_16.png'), "mark_for_destroy(this, '.icon_graphic')"%><br/> <%= icon_form.hidden_field :id, :index => nil %> <%= icon_form.hidden_field :icon, :index => nil %> <%= icon_form.hidden_field :should_destroy, :index => nil, :class => 'should_destroy' %> <br/><br/> <%- end -%> <% end -%> </div> Now, this is looking fine when I add new icons, and fill both fields. However, if I edit the IconSet after the fact, and perhaps try to replace the icon with a new one, or if I uploaded only one of the set and try to add the second attachment, paperclip doesn't put the attachments with the right IconGraphic Model. It seems that even though I have the IconGraphic ID in each partial, <%= icon_form.hidden_field :id, :index => nil %> it seems that paperclip either creates a new IconGraphic or attaches it to the wrong one. This all happens when you save the IconSet, which is setup to save the IconGraphic attributes. I know this is complicated.. I may just have to go to editing each icon individually, but if anyone can help, I would appreciate it.

  • C++ : Avoid lot of boolean variable for multiple verification conditions in trading app

    - by Naveen
    Hi i am a junior dev in trading app... we have a order refresh verification unit. It has to verify order confirmation from exchange. We send a bunch of different request in bulk ( NEW, MODIFY, CANCEL ) to exchange... Verification has to happen for max N times with each T intervals for all orders. if verification successful for all the order before N retry then fine.. otherwise we need to indicate as verification unsuccessfull. i hv done a basic coding done in very urgent like below for( N times ) { for_each ( sent_request_order ) // SENT { 1) get all the refreshed order from DB or shared mem i.e REFRESHED 2) find current sent order in REFRESHED if( not_found ) not refreshed from exchange, continue to next order if( found ) case NEW : //check for new status, mark verification done case MODIFY : //check for modified status.. //if not mark pending, go to next order, //revisit the same after T time case CANCEL : //check for cancelled status.. //if not mark pending, go to next order, //revisit the same after T time } if( all_verified ) exit from verification. wait ( T sec ) } order_verification_pending, order_verification_done, order_visited, order_not_visited, all_verified, all_not_verified ... lot of boolean flags used for indication.. is there any better approach for doing this.... splitting responsibilities across the classes......???? i know this is not a general question.... but still flags are making me tidious to handle...

  • Real-time aggregation of files from multiple machines to one

    - by dmitry-kay
    I need a tool which gets a list of machine names and file wildcards. Then it connects to all these machines (SSH) and begins to monitor changes (appendings to the end) in each file matched by wildcards. New lines in each such file are saved to the local machine to the file with the same name. (This is a task of real-time log files collecting.) I could use ssh + tail -f, of course, but it is not very robust: if a monitoring process dies and then restarts, some data from remote files may be lost (because tail -f does not save the position at which it is finished before). I may write this tool manually, but before - I'd like to know if such tool already exists or not.

  • Android multiple screen sizes and density problems

    - by Ben Mc
    I'm having a real problem with my drawables that I just can't seem to figure out. The problem is this: There are screen sizes at approximately 320x480, 480x800, 480x854 Then there are most commonly densities at 1.0 (160) and 1.5 (240) Now, on a Droid, the screen size is 480x800 and the density is reporting using DisplayMetrics as 1.5 On the G1, it's 320x480 and reporting back at a density of 1.0 BUT tablet devices are reporting back at 480x800 with a density of 1.0 (160) So, I'm going mad because I can put 320x480 images in the drawables-mdpi folder and 480x800 images in the drawables-hdpi folder, but on Tablet computers, no matter what it's not resizing up anything to a full screen. Any help would be greatly appreciated. I just want all of my 320x480 images to scale up regardless of the device.

  • Scaling Image to multiple sizes for Deep Zoom

    - by AnthonyWJones
    Lets assume I have a bitmap with a square aspect and width of 2048 pixels. In order to create a set of files need by Silverlight's DeepZoomImageTileSource I need to scale this bitmap to 1024 then to 512 then to 256 etc down to 1 pixel image. There are two, I suspect naive, approaches:- For each image required scale the original full size image to the required size. However it seems excessive to be scaling the full image to the very small sizes. Having scaled from one level to the next discard the original image and scale each sucessive scaled image as the source of the next smaller image. However I suspect that this would generate images in the 256-64 range with poor fidelity than using option 1. Note unlike with the Deep Zoom Composer this tool is expected to act in an on-demand fashion hence it needs to complete in a reasonable timeframe (tops 30 seconds). On the pluse side I'm only creating a single multiscale image not a pyramid of mutliple high-res images. I am outside my comfort zone here, any graphics experts got any advice? Am I wrong about point 2? Is point 1 reasonably performant and I'm worrying about nothing? Option 3?

  • How do i pack multiple rectangles in a 2d box tetris style

    - by mglmnc
    I have a number of rectangles of various widths and heights. I have a larger rectangular platform to put them on. I want to pack them on one side of the platform so they spread in the lengthwise (X) dimension but keep the widthwise (Y) dimension to a minimal. That is to place them like a tetris game. There can be no overlaps but there can be gaps. Is there an algorithm out there to do this?
