  • Make python display help screen if no action is given

    - by luckytaxi
    Let's say a user runs the script w/o giving any paramters. How can I make it so that it defaults to ./myscript.py -h so that it shows them the help info? parser = optparse.OptionParser() parser.add_option("-d", "--directory", metavar="DIR", help="Directory to scan for big files") parser.add_option("-e", "--email", metavar='EMAIL', help='email to send the list to') parser.add_option("-l", "--limit", metavar='LIMIT', help='return number of files')

  • Dijit Combobox filter autocomplete

    - by Apps
    I'm using dijit combobox for populating a JSON List. Also I'm using ItemFileReadStore for getting the JSON data from the server. Once the data is downloaded, when I click on the combobox it shows all the data. But I don't want the user to see all the data. The user should see the list only when he types something. I tried using queryExpr parameter-${0}*. But at that time the list is not populated.Can someone please help me to fix it? Any help will be greatly appreciated Thanks, Apps

  • Show transparent color filter on a View after clicking it

    - by Maarten
    So. You know how when you click a post in the Google+ app, the entire View becomes blue. I want to do that as well, but with an ImageView. I have the following code snippet, setting the actual image as the background and the selector as the main resource. This looks good, but doesn't respect scaleType for the background image: <ImageView android:id="@+id/painting_image" android:layout_width="match_parent" android:layout_height="200dp" android:background="@drawable/img" android:src="@drawable/selector" android:scaleType="centerCrop" /> By the way, @drawable/selector is just a selector that shows a tranparent color for state_pressed: <item android:state_pressed="true"> <shape xmlns:android="http://schemas.android.com/apk/res/android"> <solid android:color="#44521400" /> </shape></item> How can I make this work while respecting the scaleType?

  • getting the value of a filter at an arbitrary time

    - by Andiih
    Context: I'm trying to improve the values returned by the iPhone CLLocationManager, although this is a more generally applicable problem. The key is that CLLocationManger returns data on current velocity as and when it feels like it, rather than at a fixed sample rate. I'd like to use a feedback equation to improve accuracy v=(k*v)+(1-k)*currentVelocity where currentVelocity is the speed returned by didUpdateToLocation:fromLocation: and v is the output velocity (and also used for the feedback element). Because of the "as and when" nature of didUpdateToLocation:fromLocation: I could calculate the time interval since it was last called, and do something like for (i=0;i<timeintervalsincelastcalled;i++) v=(k*v)+(1-k)*currentVelocity which would work, but is wasteful of cycles. Especially as I probably want timeintervalsincelastcalled to be measured as 10ths of a second. Is there a way to solve this without the loop ? i.e. rework (integrate?) the formula so I put an interval into the equation and get the same answer as I would have by iteration ?

  • Stepping through ASP.NET MVC in Action (2009) - and stuck on nunit issue

    - by Jen
    I seem to have missed something - in this step through it talks through downloading nunit and changing the original MSTest reference to NUnit. Which seems fine until it talks about running the test with UnitRun from JetBrains. I would have thought I could run nUnit to be able to run the test - but I load my project in the nUnit gui and I get "This assembly was not built with any known testing framework". This after running the Nunit-2.5.3.9346.msi. Or am I supposed to be able to run tests from within visual studio 2008? After some research I find this: http://www.jetbrains.com/unitrun/ (ie. it seems to be saying this is no longer supported and I'm thinking JetBrains Resharper may cost money?). I'm a little rusty on my NUnit experience. So how do I go ahead and run my test? Is the error message I'm getting considered abnormal? I've added a reference in my MvcApplication.Tests project to the nunit.framework. Is this the wrong reference to add? Thanks :)

  • AJAX filter MySQL results using checkboxes

    - by keepitnang
    I'm attempting to get to grips with displaying filterable MySQL data within a PHP page based on user checkbox selections. I have a database of domain names and the dates on which these will require renewal as per Nominet DAC information and I can get unfiltered data to display, but filtering results by domain extensions is proving tricky for me to accomplish. I should point out at this stage that I am a serious newcomer to many of the ideas I am trying to learn to work with here, so please be gentle. I have tried following some other articles on here also, but no dice. I have the following so far: HTML <input type="checkbox" class="extensions" name="extensions" value=".co.uk">.co.uk</input> <input type="checkbox" class="extensions" name="extensions" value=".org.uk">.org.uk</input> Script $('.extensions').live('click', function() { var all_boxes = $('.extensions'); var all_boxes_values = []; var i = 0; for (var i; i < all_boxes.length; i++) { if (all_boxes[i].checked) { all_boxes_values.push(all_boxes[i].value) } } var all_boxes_values_clean = all_boxes_values.join(", "); console.log(all_boxes_values_clean); $.get("sql-test.php", {q: all_boxes_values_clean}, function(result) { $("div#output").html(result); } )}); PHP $g = $_GET['q']; $extensionsql=""; $extension=1; if(isset($g)) { $extension=1; $param = "" . str_replace(",", "','", $_GET['q']) . ""; } And that's as far as I have gotten with my limited ability. What I would like to do next is search the column domainName for a string match and return the appropriate results to the user. Something to mimic something like the following but I'm not sure how to achieve it. Any help would be much appreciated: SELECT * FROM `refresh` WHERE `domainName` LIKE '%.co.uk%' AND renewalDate LIKE '%2012-06-30%' ORDER BY `domainName` ASC Thanks

  • jQuery: if value is true without user action

    - by Kevin Brown
    I want to show a div if the value of an input =='CP'. Right now this is my code: $(".register-type").change(function(){ var value = $(this).val(); if(value == 'CP'){ $('.cp-show').show(); This works fine if they change the input, but if things get validated false and the page reloads, this input is still 'CP', but the div doesn't show... Is there a way to correct this so that jquery checks if this is set on the page load?

  • Is is faster to filter and get data or filter then get data ?

    - by remi bourgarel
    Hi I have this kind of request : SELECT myTable.ID, myTable.Adress, -- 20 more columns of all kind of type FROM myTable WHERE EXISTS(SELECT * FROM myLink WHERE myLink.FID = myTable.ID and myLink.FID2 = 666) myLink has a lot of rows. Do you think it's faster to do like this : SELECT myLink.FID INTO @result FROM myLink WHERE myLink.FID2 = 666 UPDATE @result SET Adress = myTable.Adress, -- 20 more columns of all kind of type FROM myTable WHERE myTable.ID = @result.ID

  • best way to filter out non-representational elements

    - by nonano
    Hi there, I am using phpQuery in order to apply some twaks to editorial content. As its syntax is the same as jQuery, I consider this a dom scripting issue. To get rid of elements which are not representing anything, but wrapping other stuff (like the div in <div><p>blah</p></div> I came up with this selector: ['div:not([align][class][id][style][title][dir][lang][onclick][ondblclick][onmousedown] [onmouseup][onmouseover][onmousemove][onmouseout][onkeypress][onkeydown][onkeyup])'] which looks quite monstrous for a selector simply aming on Divs which just do not have any (valid) attribute. I guess there must be a more straight-forward way to accomplish that, right? Edit: Oh, and I just noticed that it even doesn't do wat I intended to ...

  • Translate SQL to LINQ query - group/join/filter

    - by Paddy
    I have the following query: SELECT S.[FlowOrder], S.[DESCRIPTION], COUNT(I.ID) FROM WorkFlowStatus AS S INNER JOIN Item AS I ON S.ID = I.StatusID WHERE I.Installation = '1' GROUP BY S.[Description], S.[FlowOrder] ORDER BY S.[FlowOrder] Which gives me the count of an item, grouped by a foreign key to workflow, outputting the descriptive name from my FK table. I've go this far with the LINQ query (using LINQ-to-SQL) in the background: var items = from s in _entities.WorkflowStatus join i in _entities.Items on s.ID equals i.StatusId into Statuses orderby s.FlowOrder select new {s.Description, ItemCount = Statuses.Count() }; How do I get the where clause in the SQL into this LINQ query?

  • JavaScript, iPhone: Repeat Action while Holding Button

    - by Doug
    I am working on a website which I would like to work on iPhones, however I want it so they can tap and hold a button and have it continue firing the onclick event. I got it to work in other browsers, but the iPhone is the only one that will need to hold down the button. Is there a way to repeat a function when holding down the button? Thanks.

  • Performing an action on Parent/Child elements independently.

    - by Matt Weldon
    I have HTML similar to the following in my page <div id="someDiv"> <img src="foo.gif" class="someImg" /> </div> The wrapper div is set up such that when it is clicked, it's background-color changes using the following jQuery code. $("div").click(function(event){ $(this).css("background-color", "blue"); }); I also have some jQuery associated with my img that will do some other function (for the sake of argument I am going to display and alert box) like so: $("img[class=someImg]").click(function(event){ alert("Image clicked"); }); The issue I have come across is that when I click on the img, the event associated with the div is also triggered. I'm pretty sure that this is due to the way that jQuery (or indeed JavaScript) is handling the two DOM elements - clicking the img would require you to also technically click the div, thus triggering both events. Two questions then really: Is my understanding of the DOM/JavaScript flawed in some way or is this actually how things are occurring? Are there any jQuery methods that would allow me to perform actions on a child element without invoking those associated with its parent?

  • Example of xargs' -x option in action

    - by Ole Tange
    GNU xargs has option '-x'. The man page says: -x Exit if the size (see the -s option) is exceeded. But xargs seems to not care if -x is set or not. I have been unable to make an example in which the -x has any effect at all. Please provide two examples in which the only difference is an added -x and that produce different output.

    Hello Guys, I have a datatable with plenty of records. And i have a range like lowerRange = 10 and upperRange = 200. I want the pull the records starting at row 10 till row 200. Now i don't want to add any new index based column into the datatable. Is there any way with the help of linq, i can pull the set of rows based on some internal datatable index? I guess, the datatable must be maintaining some row index implicitly. Please suggest.

  • What does this mean in AS3?

    Hello I've started to learning AS3 from one book and found something I don't understand. Ellipse(_board[row][column]).fill = getFill(row, column); _board is two dimensional array of Ellipse type, so I just dont understand why is Ellipse(Ellipse object) used when it apparently works without it, or I haven't seen any changes when I omitted it.

  • Filter to values in collection in one query

    - by dotnetdev
    Hi, I have the following LINQ query: List<string> Types = (List<string>) Directory.GetFiles(@"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727") Where(x => System.IO.Path.GetFileNameWithoutExtension(x).Contains("Microsoft")) .ToList<string>(); How could I modify this so it can only get the values stored in a collection, without writing another LINQ query (which I assume will impact performance?)? Thanks
