• D-Day Calendar has wrong dates when importing from google calendar?

  - by chobo2

  Hi I am using D-Day calendar and I am not sure but I got a weird problem. I basically have this for my code iCalendar iCal = iCalendar.LoadFromStream(file.InputStream); foreach (Event evt in iCal.Events) { DateTime start = evt.DTStart.Date; DateTime end = evt.DTEnd.Date; // loop through it and get values. } Yet when I import a calendar from google calendar the end date is messed up on some of the stuff I am importing. Like for instance I have this Title: should not show When: Sun, March 21(all day). Yet when I import it in. I says the start date is the 21st yet the end date is the 22nd when it should be the 21st. Not sure what is going on. I am not really sure what other info I can give you guys.

• Wordpress, PHP, URL Encoding Issue

  - by Scott Porad

  Wordpress provides a function called "the_permalink()" that returns, you guessed it!, the permalink to a given post while in a loop of posts. I am trying to URL encode that permalink and when I execute this code: <?php print(the_permalink()); $permalink = the_permalink(); print($permalink); print(urlencode(the_permalink())); print(urlencode($permalink)); $url = 'http://wpmu.local/graphjam/2008/11/06/test4/'; print($url); print(urlencode($url)); ?> it produces these results in HTML: http://wpmu.local/graphjam/2008/11/06/test4/ http://wpmu.local/graphjam/2008/11/06/test4/ http://wpmu.local/graphjam/2008/11/06/test4/ http://wpmu.local/graphjam/2008/11/06/test4/ http%3A%2F%2Fwpmu.local%2Fgraphjam%2F2008%2F11%2F06%2Ftest4%2F I would expect lines 2, 3 and 5 of the output to be URL encoded, but only line 5 is so. Thoughts?

• Looping through worksheets in an Excel (xls) file using classic ASP on a win 2008 server

  - by Roy

  Hi, I have just migrated an older ASP solution to a windows 2008 server and everything works out fine except for using ADOX.Catalog to list all the worksheets in an uploaded xls file. I use the following code: <% Set objExcelCon = Server.CreateObject("ADODB.Connection") With objExcelCon .Provider = "Microsoft.ACE.OLEDB.12.0" .ConnectionString = "Data Source=" & strFilePath & "\" & strFileName & ";Extended Properties=Excel 12.0;" .Open End With Set objAdo = Server.CreateObject("ADOX.Catalog") ' Set ADOX activeConnection objAdo.activeConnection = objExcelCon ' Loop through tables (worksheets) For i = 0 To objAdo.Tables.Count - 1 response.Write objAdo.Tables(i).Name Next Set objExcelCon = Nothing Set objAdo = Nothing % When I run this i get no error message or anything. Anyone got any idea whats causing this? Best regards, Roy

• Help with split

  - by Andeeh

  I have something that splits each line of a file. here is a sample of a line it might split "James","Project5","15/05/2010","3" I have this code Private Sub Command1_Click() Open jobs For Input As #1 Do While Not EOF(1) Line Input #1, tmpstring splititems = Split(tmpstring, ",") Form1.Print splititems(0) Form1.Print splititems(1); Form1.Print splititems(2); Form1.Print splititems(3) Loop Close #1 End Sub I would like it to instead of outputting a name each time there is a name, just put the project under the name that is already there. e.g. if there was another line in the file with the name james and he had been working on project 2 in that line I would like it to just put project 2 under the "James" that had already been put on the form. Any help would be fantastic

• F# pattern matching

  - by Roger Alsing

  What would be the most effective way to express the following code? match cond.EvalBool() with | true -> match body.Eval() with | :? ControlFlowModifier as e -> match e with | Break(scope) -> e :> obj //Break is a DU element of ControlFlowModifier | _ -> next() //other members of CFM should call next() | _ -> next() | false -> null cond.EvalBool returns a boolean result where false should return null and true should either run the entire block again (its wrapped in a func called next) or if the special value of break is found, then the loop should exit and return the break value. Is there any way to compress that block of code to something smaller?

• Matching n parentheses in perl regex

  - by coding_hero

  Hi, I've got some data that I'm parsing in Perl, and will be adding more and more differently formatted data in the near future. What I would like to do is write an easy-to-use function, that I could pass a string and a regex to, and it would return anything in parentheses. It would work something like this (pseudocode): sub parse { $data = shift; $regex = shift; $data =~ eval ("m/$regex/") foreach $x ($1...$n) { push (@ra, $x); } return \@ra; } Then, I could call it like this: @subs = parse ($data, '^"([0-9]+)",([^:]*):(\W+):([A-Z]{3}[0-9]{5}),ID=([0-9]+)'); As you can see, there's a couple of issues with this code. I don't know if the eval would work, the 'foreach' definitely wouldn't work, and without knowing how many parentheses there are, I don't know how many times to loop. This is too complicated for split, so if there's another function or possibility that I'm overlooking, let me know. Thanks for your help!

• Getting a specific number of JSON items with jQuery from tumblr feed

  - by Kevin Whitaker

  Hello all. I'm trying to populate a page with X entries from my tumblr feed, and I'm wondering how I can only pull that X number from the JSON object it returns. Here's my code, pulled from another Stack Overflow post and modified: //Tumblr retrieval $.getJSON("http://tumblr-address/api/read/json?callback=?", function(data) { $.each(data.posts, function(i,posts){ var title = this["regular-title"]; var type = this.type; var date = this.date; var url = this["url-with-slug"]; $('#sideRail ol').prepend('<li><p><a href=' +url +'>' + title + '</a></p><p>' + date + '</p></li>'); }); }); I've tried using a while loop with a counter, but it just repeats everything X times before moving on to the next item in the list. Thanks for any help.

• Workflow foundation 4.0 message correlation and error reporting

  - by Lygpt

  I have a workflow service that runs and performs a number of different operations (such as web service calls). If one of these operations fails I call an error reporting web service to notify a seperate system that one of my workflow operations has failed. As the error could be something like the web service being down, I loop and retry this operation until it works. There can be times though when the data I'm passing to this web service is faulty and it needs changing. So I need to be able to hook into this running (but delayed) workflow and change local workflow variables and then re-run the operation. I've looked at message correlation in workflow 4.0 to achieve this but because the delay activity is active in my running workflow instance, any second service call doesn't do anything (it's like the delay activity is blocking any other requests). I've tried setting 'CanCreateInstance' to both true and false but it doesn't help. Thanks!

• Basecamp API Rails

  - by dannymcc

  Hi Everyone, I was wondering if someone could do me massive favour.. I really don't understand how to make use of API's - so I was wondering if, using Basecamp as an example, someone could talk me though the basics. So far I have an application with a dashboard controller/view, I have put basecamp.rb into my /lib directory, added the following to my application_controller: def basecamp_connect Basecamp.establish_connection!('XXXXXX.basecamphq.com', 'USER', 'PASS', false) @basecamp = Basecamp.new end Obviously changing the required parts to my credentials. Next up I have added the following to my dashboard_controller: def index Basecamp::TodoList.find(:all) end Next I presume I have to somehow list the Todo's on the dashboard using some sort of loop. Am I doing the right thing, if so - how on earth do I display all the todo items and if not - what am I doing wrong/missing. It doesn't have to be todo's, anything from basecamp or any other popular API service would be a good start. It's just that I happen to have a basecamp account! Thanks, Danny

• Number of lines in csv.DictReader

  - by Alan Harris-Reid

  Hi there, I have a csv DictReader object (using Python 3.1), but I would like to know the number of lines/rows contained in the reader before I iterate through it. Something like as follows... myreader = csv.DictReader(open('myFile.csv', newline='')) totalrows = ? rowcount = 0 for row in myreader: rowcount +=1 print("Row %d/%d" % (rowcount,totalrows)) I know I could get the total by iterating through the reader, but then I couldn't run the 'for' loop. I could iterate through a copy of the reader, but I cannot find how to copy an iterator. I could also use totalrows = len(open('myFile.csv').readlines()) but that seems an unnecessary re-opening of the file. I would rather get the count from the DictReader if possible. Any help would be appreciated. Alan

• Porting from GAE to TomCat or another servlet server

  - by bach

  Hi guys, I'm unhappy from GAE because - One can't have a global variable and the 'synchronize' keyword. Instead one have to catch a basically DB transcational exception and retry in a while loop - which will eat all my free CPU time and will start costing me money as I reach the google's qouata. Is it safe to use synchronize inside a doPost() in tomcat? (i guess that it's ok as long as all the servlets are running on on 1 VM?). If not in all tomcat configurations, how do I configure tomcat to make it safe? How can I convert a GAE app to my own tomcat server? - How to install DataNucleus Access Platform on tomcat? Best regards

• YouTube API Get all videos uploaded feed

  - by Paul

  Hi Guys, I can't seem to retrieve ALL videos from a particular channel on YouTube, despite the API giving example code that should perform just that. I'm using Java. http://gdata.youtube.com/feeds/api/users/GoogleDevelopers/uploads The above rss feed is the URL they suggest using along with the following sample code.. /*init the list*/ String feedUrl = "http://gdata.youtube.com/feeds/api/users/GoogleDevelopers/uploads"; VideoFeed videoFeeder = null; videoFeeder = serviceobject.getFeed(new URL(feedUrl), VideoFeed.class); Looping this with a for loop suggests 25 entries (as per the RSS). However - the actual number of videos uploaded is significantly larger. (662 at time of writing). My query is how on earth you retrieve everything with the API, not just a subset of the data. Any ideas on where I'm going wrong? Should I be using a different URL? http://www.youtube.com/GoogleDevelopers#g/a

• Faster projected-norm (quadratic-form, metric-matrix...) style computations

  - by thekindamzkyoulike

  I need to perform lots of evaluations of the form X(:,i)' * A * X(:,i) i = 1...n where X(:,i) is a vector and A is a symmetric matrix. Ostensibly, I can either do this in a loop for i=1:n z(i) = X(:,i)' * A * X(:,i) end which is slow, or vectorise it as z = diag(X' * A * X) which wastes RAM unacceptably when X has a lot of columns. Currently I am compromising on Y = A * X for i=1:n z(i) = Y(:,i)' * X(:,i) end which is a little faster/lighter but still seems unsatisfactory. I was hoping there might be some matlab/scilab idiom or trick to achieve this result more efficiently?

• Access DotNetPanel/WebsitePanel Enterprise Server from outside the loopback address

  - by Ryan French

  Hi Peoples, I am currently investigating integration of DotNetPanel/WebsitePanel with a website that is running ColdFusion. The issue I have come across is that it seems WebsitePanel only allows access to the Enterprise Server (where the web services are that I need access to) when the request is coming from the same physical machine (i.e. on the loop-back address 127.0.0.1). This unfortunately doesnt really work out too well with our current setup as we have our ColdFusion server running on one machine and WebsitePanel running on another. Does anyone have any suggestions as to how we can change this? Currently we are investigating writing a transparent proxy server that will sit on the portal machine and pass requests between the two sites, but that is less than ideal.

• Jquery Fast image switching

  - by echedey lorenzo

  Hi, I have a php class that generates a map image depending on my db data. It is periodically updated thru a serInterval loop. I am trying to update it with no flickering but I just can't. I've tried different methods (preloader, imageswitcher) with no success. //first load function map() { $("#map").html("<img src=map.php?randval="+Math.random()+">"); } //update it from setInterval calls function updatemap() { $("#map").fadeOut(function() { $(this).load(function() { $(this).fadeIn(); }); $(this).attr("src", "map.php?randval="+Math.random()); }) } Is there any way to update the image with no flickering at all? I would prefer an inmediate swap insteado of a fade. The problem I'm having is that after calling updatemap() the image just dissapears. ¿Maybe it is a problem with the attribute src I am parsing? THanks for your help.

• Add title to jQuery Cycle slideshow from Alt attribute?

  - by thatryan

  I am building a slideshow and need to have a title appear for each picture that get cycled. I created alt attributes for them and am trying to have cycle display them for each image, but It only shows the first one. I am unsure how to get the code I have into the cycle "loop" for the gallery? Does this make sense? here is what I have, (well, part of it I mean) :) thanks! $('#slideshow').before('<div class="navigation">').cycle({ fx: 'fade', timeout: 6000, pager: '.navigation' }); $('.image_title').html($(this).find('img').attr('alt'));

• Sending and receiving async over multiprocessing.Pipe() in Python

  - by dcolish

  I'm having some issues getting the Pipe.send to work in this code. What I would ultimately like to do is send and receive messages to and from the foreign process while its running in a fork. This is eventually going to be integrated into a pexpect loop for talking to interpreter processes. ` from multiprocessing import Process, Pipe def f(conn): cmd = '' if conn.poll(): cmd = conn.recv() i = 1 i += 1 conn.send([42 + i, cmd, 'hello']) if __name__ == '__main__': parent_conn, child_conn = Pipe() p = Process(target=f, args=(child_conn,)) p.start() from pdb import set_trace; set_trace() while parent_conn.poll(): print parent_conn.recv() # prints "[42, None, 'hello']" parent_conn.send('OHHAI') p.join() `

• Huge dataset point in polygon in .net (collision detection)

  - by Rickard Liljeberg

  I have a pretty big mesh with polygons, usually triangles but sometimes rectangles. Each point in my mesh has a value (value has nothing to do with coordinates). Now I am creating a second mesh in the same coordinate-space as the old mesh. I now want to interpolate out values for all points (vertices) in the new mesh using the values from the old mesh. Now I could loop each polygon in the new mesh and detect which old vertices are in each polygon by making 2d collision detection (altho even this I don't get to function properly so if anyone has simple and fast code for 2d collision detection (triangle is enough) I would gladly see it). However to my main point again. looping each old vertice for each new polygon seems less than efficient. is there a better way?

• Liquid templates - accessing members by name

  - by egarcia

  I'm using Jekyll to create a new blog. It uses Liquid underneath. Jekyll defines certain "variables": site, content, page, post and paginator. These "variables" have several "members". For instance, post.date will return the date of a post, while post.url will return its url. My question is: can I access a variable's member using another variable as the member name? See the following example: {% if my_condition %} {% assign name = 'date' %} {% else %} {% assign name = 'url' %} {% endif %} I have a variable called name which is either 'date' or 'url'. How can I make the liquid equivalent of post[name] in ruby? The only way I've found is using a for loop to iterate over all the pairs (key-value) of post. Beware! It is quite horrible: {% for property in post %} {% if property[0] == name %} {{ property[1] }} {% endif %} {% endfor %} Argh! I hope there is a better way. Thanks.

• maximum execution time for javascript

  - by Andrew Chang

  I know both ie and firefox have limits for javascript execution here: hxxp://support.microsoft.com/?kbid=175500 Based on number of statements executed, I heard it was 5 million somewhere in ie hxxp://webcache.googleusercontent.com/search?q=cache:_iKHhdfpN-MJ:kb.mozillazine.org/Dom.max_script_run_time+dom.max_script_run_time&hl=en&gl=ca&strip=1 (google cache since site takes forever to load for me) based on number of seconds in firefox, it's 10 seconds by default for my version The thing I don't get is what cases will go over these limits: I'm sure a giant loop will go over the limit for execution time But will an event hander go over the limit, if itself it's execution time is under the limit but if it occurs multiple times? Example: Lets say I have a timer on my page, that executes some javascript every 20 seconds. The execution time for the timer handler is 1 second. Does firefox and ie treat each call of the timer function seperatly, so it never goes over the limit, or is it that firefox/ie adds up the time of each call so after the handler finishes, so after 200 seconds on my site (with the timer called 10 times) an error occurs even though the timer handler itself is only 1 second long?

• Formula needed: Sort array to array-"snaked"

  - by aw

  After the you guys helped me out so gracefully last time, here is another tricky array sorter for you. I have the following array: a = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16] I use it for some visual stuff and render it like this: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Now I want to sort the array to have a "snake" later: // rearrange the array according to this schema 1 2 3 4 12 13 14 5 11 16 15 6 10 9 8 7 // the original array should look like this a = [1,2,3,4,12,13,14,5,11,16,15,6,10,9,8,7] Now I'm looking for a smart formula / smart loop to do that ticker = 0; rows = 4; // can be n cols = 4; // can be n originalArray = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16]; newArray = []; while(ticker < originalArray.length) { //do the magic here ticker++; } Thanks again for the help.

• Join collection of objects into comma-separated string

  - by Helen Toomik

  In many places in our code we have collections of objects, from which we need to create a comma-separated list. The type of collection varies: it may be a DataTable from which we need a certain column, or a List<Customer>, etc. Now we loop through the collection and use string concatenation, for example: string text = ""; string separator = ""; foreach (DataRow row in table.Rows) { text += separator + row["title"]; separator = ", "; } Is there a better pattern for this? Ideally I would like an approach we could reuse by just sending in a function to get the right field/property/column from each object.

• Parsing atom/rss feed containing multiple <link> tags with Haml on RoR

  So, firstly, heres an atom feed snippet which i am trying to parse: // http://somelink.com/atom <feed xmlns="http://www.w3.org/2005/Atom"> <entry> <title>Title Here</title> <link href="http://somelink.com/link1&amp;amp;ref=rss" rel="alternate" /> <link href="http://somelink.com/link2&amp;amp;ref=rss" rel="tag:somelink.com/apply_url"/> ... </entry> i pull the atom feed like so, // In controller index method @rss = SimpleRSS.parse open('http://somelink.com/atom') Then i output the response in the view, which i am writing using haml, as follows: - @rss.entries.each do |item| .title-div = item.title .title-link = item.link //outputs the first link I could run a second loop for the links but is there a way to get the second link without it? Like reading the "rel" attribute and outputting the correct link? How do i do this in haml/rails?

• How to scroll to the new added item in a ListView

  - by Thomas

  Hi all My application show a ListView with a button which allow user to add an element. When the user clicks on this button, another Activity is started to allow user to populate the new element. When the add is finished, we return to the previous Activity with the ListView and I would like to scroll to the new element. Note that this element is not necessarily at the end of the ListView because there is an "order by" when I retrieve the datas from the database. I know I need the cursor position of the new element to make the ListView scrool to it, but the only info I have about this element is its id, so how to convert this id to cursor position ? Do I have to loop on the cursor to find the position ? Thanks in advance
