• Comparing lists in Standard ML

  - by user1050640

  I am extremely new to SML and we just got out first programming assignment for class and I need a little insight. The question is: write an ML function, called minus: int list * int list -> int list, that takes two non-decreasing integer lists and produces a non-decreasing integer list obtained by removing the elements from the first input list which are also found in the second input list. For example, minus( [1,1,1,2,2], [1,1,2,3] ) = [1,2] minus( [1,1,2,3],[1,1,1,2,2] ) = [3] Here is my attempt at answering the question. Can anyone tell me what I am doing incorrectly? I don't quite understand parsing lists. fun minus(xs,nil) = [] | minus(nil,ys) = [] | minus(x::xs,y::ys) = if x=y then minus(xs,ys) else x :: minus(x,ys); Here is a fix I just did, I think this is right now? fun minus(L1,nil) = L1 | minus(nil,L2) = [] | minus(L1,L2) = if hd(L1) > hd(L2) then minus(L1,tl(L2)) else if hd(L1) = hd(L2) then minus(tl(L1),tl(L2)) else hd(L1) :: minus(tl(L1), L2);

  Anyone know where I can find information on how I can control the USB port on a Droid running Android 2.0? I want to know how to either initialize the USB port or send data across it vi a program. I want to be able to atatch a device to the USB port to act as a switch to control a microservo. So when I said "send data" across the port, I just need to be able to energize the transmit pin on the USB to turn the servo on. Thanks ahead, Tom

• Quick MVC2 checkbox question

  - by kevinmajor1

  In order to get my EF4 EntityCollection to bind with check box values, I have to manually create the check boxes in a loop like so: <p> <%: Html.Label("Platforms") %><br /> <% for(var i = 0; i < Model.AllPlatforms.Count; ++i) { %> <%: Model.AllPlatforms[i].Platform.Name %> <input type="checkbox" name="PlatformIDs" value="<%: Model.AllPlatforms[i].Platform.PlatformID %>" /><br /> <% } %> </p> It works, but it doesn't automatically populate the group of check boxes with existing values when I'm editing a model entity. Can I fudge it with something like? <p> <%: Html.Label("Platforms") %><br /> <% for(var i = 0; i < Model.AllPlatforms.Count; ++i) { %> <%: Model.AllPlatforms[i].Platform.Name %> <input type="checkbox" name="PlatformIDs" value="<%: Model.AllPlatforms[i].Platform.PlatformID %>" checked=<%: Model.GameData.Platforms.Any(p => PlatformID == i) ? "true" : "false" %> /><br /> <% } %> </p> I figure there has to be something along those lines which will work, and am just wondering if I'm on the right track. EDIT: I'm purposely staying away from MVC's check box HTML helper methods as they're too inflexible for my needs. My check boxes use integers as their values by design.

• Use Zip to Pre-Populate City/State Form with jQuery AJAX

  - by Paul

  I'm running into a problem that I can solve fine by just submitting a form and calling a db to retrieve/echo the information, but AJAX seems to be a bit different for doing this (and is what I need). Earlier in a form process I ask for the zip code like so: <input type="text" maxlength="5" size="5" id="zip" /> Then I have a button to continue, but this button just runs a javascript function that shows the rest of the form. When the rest of the form shows, I want to pre-populate the City input with their city, and pre-populate the State dropdown with their state. I figured I would have to find a way to set city/state to variables, and echo the variables into the form. But I can't figure out how to get/set those variables with AJAX as opposed to a form submit. Here's how I did it without ajax: $zip = mysql_real_escape_string($_POST['zip']); $q = " SELECT city FROM citystatezip WHERE zip = $zip"; $r = mysql_query($q); $row = mysql_fetch_assoc($r); $city = $row['city']; Can anybody help me out with using AJAX to set these variables? Thanks!

• database structure

  - by jindalsyogesh

  I have a table named ActivityRecording. This table currently has 500,000 records. I need to add a lot of new inputs that relates to activityrecording table. The relation of activityrecording with these new input fields is 1 to 0,1. So, what's going to happen on screen is when user fills the ActivityRecording data, he will then be taken to a new page and this page will show a form based on the user's input (from a dropdown named service) in activityrecording. There will 6 different kinds of form (each form will have 7-8 inputs which includes textareas of size 5kb, textboxes and checkboxes). So, for one activityrecording user will fill one out of 6 forms. There are two ways I know (there could be more), I can design the data structure: Add all the inputs from all these 6 forms into the activityrecording table. So, columns belonging to 5 of these forms will be null in this table, only columns belonging to one of the forms will have values The other way would be add 6 new tables (one for each form) and add 6 foreign key columns to activityrecording table. So, out of 6 foreign keys, 5 will be null and one will actually point to a table Which approach is a better data structure design? Please take into consideration that number of rows in this table are 500,000 and are expected to grow at a faster rate now.

• Trigger ad-hoc activity within a workflow

  - by Chris Taylor

  I am looking to use WF 4 to replace an existing workflow solution we have. One feature that is currently used in the existing workflow engine is the ability to cancel a current activity and loopback to a FlowSwitch type activity. So given the following crude workflow where we start at 'O' and base in the input data the workflow follows the path to 'A2' which is currently blocking on s bookmark waiting for input. ---------A1--\ | \ /\ \ O------- ---->--(A2)-------| ^ \/ / | | | / | | ---------A3--/ | | | |----------------------| However in the meantime some out of band data comes in that means we should cancel 'A2' and return to the FlowSwitch to re-evaluate based on the new data. The question is what is the best way to handle the out of band data that arrived? My initial guess is to have a Parallel activity with one branch waiting for out of band data and the other branch containing the workflow sequence described above. If data came in on the brach waiting for the out of band data, how would I cancel the current activity in the workflow and force it to return to the FlowSwitch. Or of course is there a better way to handle this. I have not actually done any work with the WF4 stuff for WF3 for that matter so I might be missing something obvious here.

• Update or Insert Row depending on whether row is present in Microsoft SQL Server 2005

  - by Srikanth

  Hi, I am passing a XML document as a input to a stored procedure in Microsoft SQL Server 2005. This is the sample XML being passed as input <Strategy StrategyID="0" TOStrategyID="8" ShutdownQtySell="1" ShutdownQtyBuy="1"> <ParameterRange ParameterSetID="6" ParameterRangeID="1" ParameterRangeFrom="0" ParameterRangeTo="20" ParameterAutoTakeOut="False"> </ParameterRange> <ParameterRange ParameterSetID="6" ParameterRangeID="4" ParameterRangeFrom="21" ParameterRangeTo="40" ParameterAutoTakeOut="False"> </ParameterRange> <ParameterRange ParameterSetID="6" ParameterRangeID="5" ParameterRangeFrom="41" ParameterRangeTo="60" ParameterAutoTakeOut="False"> </ParameterRange> <ParameterRange ParameterSetID="6" ParameterRangeID="6" ParameterRangeFrom="61" ParameterRangeTo="80" ParameterAutoTakeOut="False"> </ParameterRange> <ParameterRange ParameterSetID="6" ParameterRangeID="7" ParameterRangeFrom="81" ParameterRangeTo="100" ParameterAutoTakeOut="False"> </ParameterRange> </Strategy> I am able to retrieve the data using OpenXML functionality in SQL server I am using this to get the data corresponding to ParameterRange rows SELECT ParameterRangeID as iRangeID, ParameterSetID as iSetID, ParameterRangeFrom as fRangeFrom, ParameterRangeTo as fRangeTo, ParameterAutoTakeOut as bTakeoutEnabled FROM OPENXML(@idoc, '/Strategy/ParameterRange', 1) WITH (ParameterSetID int,ParameterRangeID int,ParameterRangeFrom float,ParameterRangeTo float,ParameterAutoTakeOut bit) Now, I need to insert/update these rows into a table TempRanges which has (iRangeID,iSetID) as the primary key. If there is a row with the primary key, I want to update it the latest values and If there is no row with that primary key, I need to insert into the table. How can I accomplish this inside the Stored Procedure ? Thanks, Sri

• search form in php via ajax

  - by fusion

  i've a search form wherein the database query has been coded in php and the html file calls this php file via ajax to display the results in the search form. the problem is, i would like the result to be displayed in the same form as search.html; yet while the ajax works, it goes to search.php to display the results. search.html: <!DOCTYPE html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <script src="scripts/search_ajax.js" type="text/javascript"></script> </head> <body> <form id="submitForm" method="post"> <div class="wrapper"> <div class="field"> <input name="search" id="search" /> </div><br /> <input id="button1" type="submit" value="Submit" class="submit" onclick="run_query();" /><br /> </div> <div id="searchContainer"> </div> </form> </body> </html> if i add action="search.php" to the form tag, it displays the result but on search.php. i'd like it to display on the same form [i.e search.html, and not search.php] if i just add the javascript function [as done above], it displays nothing on search.html

• Uploading a file fails under WordPress

  - by Ash

  I'm using WordPress and I'm following W3's guide for uploading a file: HTML code: <html> <body> <form action="upload_file.php" method="post" enctype="multipart/form-data"> <label for="file">Filename:</label> <input type="file" name="file" id="file" /> <br /> <input type="submit" name="submit" value="Submit" /> </form> </body> </html> PHP code (upload_file.php): <?php if ($_FILES["file"]["error"] > 0) { echo "Error: " . $_FILES["file"]["error"] . "<br />"; } else { echo "Upload: " . $_FILES["file"]["name"] . "<br />"; echo "Type: " . $_FILES["file"]["type"] . "<br />"; echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />"; echo "Stored in: " . $_FILES["file"]["tmp_name"]; } ?> The HTML code is pasted in a PHP page template and the PHP file under the WP installation directory under www. The problem is when I submit the file I get Error: 1. If I remark the "if" part of the PHP code and leave the "else" part I get: Upload: IMG_4258.JPG Type: Size: 0 Kb Stored in: So at least I know the PHP code is running. But what's causing it to fail? Is there a problem with the code or is WordPress meddling with the process?

• Using a randomly generated token for flood control.

  - by James P

  Basic setup of my site is: user enters a message on the homepage, hits enter and the message is sent though a AJAX request to a file called like.php where it echo's a link that gets sent back to the user. I have made the input disable when the user presses enter, but there's nothing stopping the user from just constantly flooding like.php with POST request and filling up my database. Someone here on SO told me to use a token system but didn't mention how. I've seen this being done before and from what I know it is effective. The only problem I have is how will like.php know it's a valid token? My code is this at the moment: $token = md5(rand(0, 9999) * 1000000); and the markup: <input type="hidden" name="token" value="<?php echo $token ?>" /> Which will send the token to like.php through POST. But how will like.php know that this is a valid token? Should I instead token something that's linked to the user? Like their IP address? Or perhaps token the current minute and check that it's the same minute in like.php... Any help on this amtter would be greatly appreciated, thanks. :)

• Set a callback function to a new window in javascript

  - by SztupY

  Is there an easy way to set a "callback" function to a new window that is opened in javascript? I'd like to run a function of the parent from the new window, but I want the parent to be able to set the name of this particular function (so it shouldn't be hardcoded in the new windows page). For example in the parent I have: function DoSomething { alert('Something'); } ... <input type="button" onClick="OpenNewWindow(linktonewwindow,DoSomething);" /> And in the child window I want to: <input type="button" onClick="RunCallbackFunction();" /> The question is how to create this OpenNewWindow and RunCallbackFunction functions. I though about sending the function's name as a query parameter to the new window (where the server side script generates the appropriate function calls in the generated child's HTML), which works, but I was thinking whether there is another, or better way to accomplish this, maybe something that doesn't even require server side tinkering. Pure javascript, server side solutions and jQuery (or other frameworks) are all welcomed.

• iPhone - How do I find the MAC address of the connected WiFi access point?

  - by Ciaran

  Without using the private APIs, is it possible to programatically determine the MAC address of the access point that the iPhone is connected to? I understand that this should be doable using the core BSD libraries, but we are new to this, so it would be great if someone can point us to some starter code. Note: we're trying to determine the MAC address of the remote device - not the MAC address of the iPhone.

• Checking if radio buttons are checked in Firefox

  - by Andrew Song

  On my site, I have two checkboxes created in my ASP.NET MVC view like so: Html.RadioButton("check", "true", "true" == (string) ViewData["someKey"], new { id = "check1"}); Html.RadioButton("check", "false", "false" == (string) ViewData["someKey"], new { id = "check2"}); I am positive that ViewData["someKey"] has the value "true" in it. In my JS init function, I perform the following check: alert($('#check1').is(':checked') + " " + $('#check2').is(':checked')); In Firefox (and only Firefox), my alert dialog will show the following (it works as expected in every other browser): Initial page load: true false Normal refresh via Ctrl + R: false false Refresh skipping cache via Ctrl + Shift + R: true false I have tried many different methods of looking at the checkbox value, including $('#check1').attr('checked') without success. If I examine the HTML in Firebug, I can see that the first radio button has the property checked="checked" in it. Why is the checkbox value changing in FF when I refresh, and how can I mitigate this? Since this seems to be a FF-only bug, how can I change my code to make it work? This SO question seemed to ask something similar, but none of the proposed solutions seem to work in this case. Edit: I should also point out that when the radio button is rendered after the refresh in FF, it's not actually being displayed as checked either, despite what the HTML is telling me. Edit2: Adding raw HTML as per request <input id="check1" type="radio" value="True" name="check" checked="checked"/> <input id="check2" type="radio" value="False" name="check"/>

• Pass Linq Expression to a function

  - by Kushan Hasithe Fernando

  I want to pass a property list of a class to a function. with in the function based on property list I'm going to generate a query. As exactly same functionality in Linq Select method. Here I'm gonna implement this for Ingress Database. As an example, in front end I wanna run a select as this, My Entity Class is like this public class Customer { [System.Data.Linq.Mapping.ColumnAttribute(Name="Id",IsPrimaryKey=true)] public string Id { get; set; } [System.Data.Linq.Mapping.ColumnAttribute(Name = "Name")] public string Name { get; set; } [System.Data.Linq.Mapping.ColumnAttribute(Name = "Address")] public string Address { get; set; } [System.Data.Linq.Mapping.ColumnAttribute(Name = "Email")] public string Email { get; set; } [System.Data.Linq.Mapping.ColumnAttribute(Name = "Mobile")] public string Mobile { get; set; } } I wanna call a Select function like this, var result = dataAccessService.Select<Customer>(C=>C.Name,C.Address); then,using result I can get the Name and Address properties' values. I think my Select function should looks like this, ( *I think this should done using Linq Expression. But im not sure what are the input parameter and return type. * ) Class DataAccessService { // I'm not sure about this return type and input types, generic types. public TResult Select<TSource,TResult>(Expression<Func<TSource,TResult>> selector) { // Here using the property list, // I can get the ColumnAttribute name value and I can generate a select query. } } This is a attempt to create a functionality like in Linq. But im not an expert in Linq Expressions. There is a project call DbLinq from MIT, but its a big project and still i couldn't grab anything helpful from that. Can someone please help me to start this, or can someone link me some useful resources to read about this.

• Adding select menu default value via JS?

  - by purpler

  Hi, i'm developing a meta search engine website, Soogle and i've used JS to populate select menu.. Now, after the page is loaded none of engines is loaded by default, user needs to select it on his own or [TAB] to it.. Is there a possibility to preselect one value from the menu via JS after the page loads? This is the code: Javascript: // SEARCH FORM INIT function addOptions(){ var sel=document.searchForm.whichEngine;for(var i=0;i<arr.length;i++){ sel.options[i]=new Option(arr[i][0],i)}} function startSearch(){ searchString=document.searchForm.searchText.value;if(searchString!=""){ var searchEngine=document.searchForm.whichEngine.selectedIndex; var finalSearchString=arr[searchEngine][1]+searchString;location.href=finalSearchString}return false} function checkKey(e){ var character=(e.which)?e.which:event.keyCode;if(character=='13'){ return startSearch()}} // SEARCH ENGINES INIT var arr = new Array(); arr[arr.length] = new Array("Web", "http://www.google.com/search?q="); arr[arr.length] = new Array("Images", "http://images.google.com/images?q="); arr[arr.length] = new Array("Knoweledge","http://en.wikipedia.org/wiki/Special:Search?search="); arr[arr.length] = new Array("Videos","http://www.youtube.com/results?search_query="); arr[arr.length] = new Array("Movies", "http://www.imdb.com/find?q="); arr[arr.length] = new Array("Torrents", "http://thepiratebay.org/search/"); HTML: <body onload="addOptions();document.forms.searchForm.searchText.focus()"> <div id="wrapper"> <div id="logo"></div> <form name="searchForm" method="POST" action="javascript:void(0)"> <input name="searchText" type="text" onkeypress="checkKey(event);"/> <span id="color"></span> <select tabindex="1" name="whichEngine" selected="Web"></select> <br /> <input tabindex="2" type="button" onClick="return startSearch()" value="Search"/> </form> </div> </body>

• jQuery Checkbox Error

  Hello, I am working on a jQuery-based todo list interface, and have hit a bit of a wall. The jQuery I am working with is a bit hacked together from various tutorials I have read, as I'm a bit of a beginner. $('#todo input:checkbox').click(function(){ var id = this.attr("value"); if(!$(this).is(":checked")) { alert("Starting."); $.ajax({ type: "GET", url: "/todos/check/"+id, success: function(){ alert("It worked.") } }); } }) This is the HTML I am using, <div id="todo"> <input type="checkbox" checked="yes" value="1"> Hello, world. <br /> </div> Any help on this would be greatly appreciated. For reference, thereason I have alerts in the jQuery is for debugging. The reason I can tell the code isn't working is because I am not getting these alerts. Thanks.
