• Inability to detect the Output from inside a SSIS script component

  - by Danaja

  In the script of the script components the Output buffer is not being detected as an existing component. I am trying to use the following piece of code Output0Buffer.AddRow(); within the public override void Input0_ProcessInputRow(Input0Buffer Row) method. I know it should be available within this method because at the moment I am copying and using a component from a previous project that has this code and it works. but when I create a new component and put the same code in it doesn't Can any one explain why this is happening?

• Sum up values in SQL once all values are available

  - by James Brown

  I have events flowing into a MySQL database and I need to group and sum the events to transactions and store away into another table. The data looks like: +----+---------+------+-------+ | id | transid | code | value | +----+---------+------+-------+ | 1 | 1 | b | 12 | | 2 | 1 | i | 23 | | 3 | 2 | b | 34 | | 4 | 1 | e | 45 | | 5 | 3 | b | 56 | | 6 | 2 | i | 67 | | 7 | 2 | e | 78 | | 8 | 3 | i | 89 | | 9 | 3 | i | 90 | +----+---------+------+-------+ The events arrive in batches and I would like to create the transaction by summing up the values for each transid, like: select transid, sum(value) from eventtable group by transid; but only after all the events for that transid have arrived. That is determined by the event with the code e (b for the beginning, e for the end and i for varying amount of intermediates). Being a novice in SQL, how could I implement the requirement for the existance of the end code before the summing?

• How to run a widget inside of an activity in Android?

  - by user220755

  I have a widget built to give the user the chance to choose the date (I did not build it, I am building on top of an open source software). Now, I need to display this widget inside of a class that extends the activity class in Android. Let me show some code. Let us say this is the activity class: public class RandomClass extends Activity { public void onCreate(Bundle savedInstanceState) { // I want to run the widget here when the class is created // (the activity is created) } } The widget i want to run is a widget that lets the user choose the date. I know I code use one of Android's activities but I need to build on top of the code so I have to run it inside of the activity class I created. Sorry if this is not clear, ask any questions and i will be more than glad to answer them and clarify.

• How might you unobtrusively enhance the jQuery Datepicker class?

  - by Teflon Ted

  You can pass special strings into jQuery's Datepicker class setDate() method like "+7" which will be translated into "7 days from today": http://docs.jquery.com/UI/Datepicker#method-setDate But you can't get that "+7" back out. When you call getDate() you get the calculated resulting date. I have a use case where I need to pull out the special string "+7" for propagation. One chunk of code is passing a special string into the Datepicker and passing the Datepicker over to another chunk of code which pulls out the date, but the latter sometimes needs to know the special string rather than the calculated date. So I need to enhance the Datepicker tool to (a) store the special code internally and (b) expose it via a method like getOriginallyPassedInDate() or some such. I'm not a jQuery/Javascript ninja so I could really use some guidance on how I might preferably-unobtrusively add the necessary functionality to the Datepicker class, the way you might monkey-patch an object in Ruby I'm guessing.

• Xcode 3.2 not recompiling changed files

  - by Jason

  I've been programming a new iPhone application and everything has been chugging along fine, until this afternoon when I noticed that any changes I was making were not being reflected in the actual app! Even code that throws errors isn't getting picked up by the compiler. To get around this, I have taken to the following procedure: Finish making my edits, and add code to the file which will always throw a compiler error. Right-click the file I have just edited, and hit "Compile" to just compile that one file; it will throw the error. Remove the error-producing code, and again right-click and "Compile" the one file. Build the whole project This is quite annoying, and I can't figure out why this would suddenly happen to my Xcode project. Any thoughts on what could be causing this, and how to fix it?

  I spot some interesting articles about exception handle in CodeProject http://www.codeproject.com/KB/cpp/seexception.aspx After reading, I decided to do some experiment. The first time I try to execute the following code char *p; p[0] = 0; The program died without question. But After several times when I executed the same problem binary code, it magically did fine. Even the following code is doing well. Any clue or explanation? char *p p[1000] = 'd'; cout<<p[1000]<<endl; My O/S is Windows 7 64bit and compiler is VS2008 rc1.

• PODS + WP Theme

  - by Sharath

  So I managed to setup pods and create my custom tables. Now I want to revamp my theme so that it pulls data from the POD table. Doesn't seem to be working... This is what I did.. I have a Pod called 'project_type' with a name (string) and a code (string) field. Have also added 3 entries via the admin system. I made a copy of the default wordpress plugin and renamed it to myTheme and activated it. Inside index.php of myTheme, I removed all the default code.. and have just the POD specific code as shown below. <?php echo "Hello World"; $p = new Pod('project_type'); echo $p->getTotalRows(); ?> However, when I reload my page, only Hello World shows up? A bit new to Wordpress so kindly advice.

• Backbone.js "model" query

  - by Novice coder

  I'm a learning coder trying to understand this code from a sample MVC framework. The below code is from a "model" file. I've done research on Backbone.js, but I'm still confused as to exactly how this code pull information from the app's database. For example, how are base_url, Model.prototype, and Collection.prototype being used to retrieve information from the backend? Any help would be greatly appreciated. exports.definition = { config : { "defaults": { "title": "-", "description": "-" }, "adapter": { "type": "rest", "collection_name": "schools", "base_url" : "/schools/", } }, extendModel: function(Model) { _.extend(Model.prototype, { // Extend, override or implement Backbone.Model urlRoot: '/school/', name:'school', parse: function(response, options) { response.id = response._id; return response; }, }); return Model; }, extendCollection: function(Collection) { _.extend(Collection.prototype, { // Extend, override or implement Backbone.Collection urlRoot: '/schools/', name: 'schools', }); return Collection; } }

  - by user2949519

  I have an Android app. Basically what it does is that user can search a car reference no. in EditText for example:- 270/30 and retrieve all the details of the particular car with the same column value in the database.

• Can I extends a sub class of Proxy class?

  - by KCBérenger

  I want to create a complete (and real) 2-dimensional array. In order to use a maximum of Adobe code, I want to use ListCollectionView which can manage sort and filters. But to use a second dimension, I need to override getProperty method, like following code. package { import flash.utils.flash_proxy; import mx.collections.ListCollectionView; public class SubClass extends ListCollectionView /* extends Proxy */ { override flash_proxy function getProperty(name : *) : * { ... } override flash_proxy function setProperty(name : *, value : *) : void { ... } } } This code doesn't work. Flash Builder 4 said to me: 1004 Namespace was not found or is not a compile-time constant. If anyone has a solution or a clue...

• Generating pagination links

  - by alpheus

  I am trying to implement a paging system that displays nearby page numbers as well as pages at each extreme. For example, if the user is on page 20 of 40, the following links should be displayed: 1, 2 ... 18, 19, [20], 21, 22 ... 39, 40. The solution would be similar to the one described here: http://90poe.com/alex-lee-on-bell-curve-pagination I have seen code to do this in PHP, but not in ASP.net (ideally I am looking for C# code). If anyone has done anything like this previously, it would be very helpful to see your code.

• .click() callback references local variable from the calling method instead of copying by value

  - by Eric Freese

  The following jQuery Javascript code is included on an otherwise empty page. $(function() { for (var i = 0; i < 10; i++) { element = $('<div>' + i + '</div>'); element.click(function() { alert(i); }); $('body').append(element); } }); The desired behavior is that this code should generate 10 div elements numbered from 0 to 9. When you click on a div element, an alert popup will show the number of the div element you clicked on (i.e. if a user clicks on the div element labeled '4', the alert popup should show the number 4). The alert popup instead shows the number 10 regardless of which div element is clicked on. How can I modify this code to make it behave in the desired way?

• Non-CDN hosted jQuery caused some strange behaviour

  - by kwokwai

  Hi all, I was using this JQuery in this download link, and included it in the head tag of a HTML web page: <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script> In a php web page, I got these few lines of codes: $.ajax({ url: 'http://mywebsite.com/site1/toavail/, type: "post", success: function(data) { // some more code here } }); When I tested the HTML page in IE 6, and 7, I saw the same warning message: "permission denied" When I tested it in Firefox 3, nothing was returned from the server web page. Later, I changed the JQuery source link to be: http://code.jquery.com/jquery-1.4.2.js I refreshed the web page, and I could saw the returned value then.

• Save the contents of manipulated div to a variable and pass to php file

  - by Danielle Zarcaro

  I have tried to use AJAX, but nothing I come up with seems to work correctly. I am creating a menu editor. I echo part of a file using php and manipulate it using javascript/jquery/ajax (I found the code for that here: http://www.prodevtips.com/2010/03/07/jquery-drag-and-drop-to-sort-tree/). Now I need to get the edited contents of the div (which has an unordered list in it) I am echoing and save it to a variable so I can write it to the file again. I couldn't get that resource's code to work so I'm trying to come up with another solution. If there is a code I can put into the $("#save").click(function(){ }); part of the javascript file, that would work, but the .post doesn't seem to want to work for me. If there is a way to initiate a php preg_match in an onclick, that would be the easiest. Any help would be greatly appreciated.

• WPF UserControl event called only once?

  - by 742

  Hi Everyone, I need to bind two-way a property of a user control to a property of a containing user control. I also need to set a default value to the property from code in the child (cannot be done easily from XAML tags). If I call my code from the child constructor, the value is set in the parent but the change callback routine is not triggered (my understanding is that the parent doesn't yet exist at the time the child is created). My current workaround is to catch the Loaded event of the child and to call the code from the handler. Howver as Loaded is called more than once, I need to set a flag to set the property only the first time. I don't like this way, but I don't know if there is a single shot event that could be used, or if this can be done otherwise. Any feedback based on your experience?

• Perl - string matching issue

  - by user2886545

  I have a problem I cannot understand. I have this string: gene_id "siRNA_Z27kG1_20543"transcript_id "siRNA_Z27kG1_20543_X_1";tss_id "TSS124620" And I want to change the gene_id. So, I have the following code: if ($line =~ /;transcript_id "([A-Za-z0-9:\-._]*)(_[oxOX][_.][0-9]*)";/) { $num = $2; $line =~ s/gene_id "([A-Za-z0-9:\-._]*)";/gene_id "$1$num";/g; print $new $line."\n"; } The aim of my code is to change siRNA_Z27kG1_20543 for siRNA_Z27kG1_20543_X_1. However, my code does not produce that output. Why? I can't understand that. My regex needs to be as it is because I match other strings (this time with success). Thanks.

• RSpec: in-depth differences between before(:all) and before(:each)

  - by gmile

  Ok, so I've ran into a very strange issue, directly connected with before blocks. I'm doing a integration testing via Watir and RSpec. For a simple test to check if user can perform a login I'm creating a 'user' record in the db by means of factory_girl. So I put the following code: before(:each) do @user = Factory(:user) end if "should perform a login" do # do stuff end In do stuff I call a browser and see how the user tries to login. Unfortunately, somehow he cannot do that — "Username isn't valid". After some investigation I discovered that if I put the code for creating user in before(:all) block, everything magically works. How's that? What's the difference between :all and :each in this context? Also, If I put the code for creating user actually in the test body, it still doesn't work (i.e. user somehow isn't added to the DB or something).
