  • Compiled Queries and "Parameters cannot be sequences"

    - by David B
    I thought that compiled queries would perform the same query translation as DataContext. Yet I'm getting a run-time error when I try to use a query with a .Contains method call. Where have I gone wrong? //private member which holds a compiled query. Func<DataAccess.DataClasses1DataContext, List<int>, List<DataAccess.TestRecord>> compiledFiftyRecordQuery = System.Data.Linq.CompiledQuery.Compile <DataAccess.DataClasses1DataContext, List<int>, List<DataAccess.TestRecord>> ((dc, ids) => dc.TestRecords.Where(tr => ids.Contains(tr.ID)).ToList()); //this method calls the compiled query. public void FiftyRecordCompiledQueryByID() { List<int> IDs = GetRandomInts(50); //System.NotSupportedException //{"Parameters cannot be sequences."} List<DataAccess.TestRecord> results = compiledFiftyRecordQuery (myContext, IDs); }

  • XmlHttpRequest in a bookmarklet returns empty responseText on GET?

    - by David Eyk
    I'm trying to build a javascript bookmarklet for a special URL shortening service we've built at http://esv.to for shortening scripture references (i.e. "Matthew 5" becomes "http://esv.to/Mt5". The bookmarklet is supposed to do a GET request to http://api.esv.to/Matthew+5, which returns a text/plain response of http://esv.to/Mt5. The code for the bookmarklet itself looks like this (expanded for readability): var body = document.getElementsByTagName('body')[0], script = document.createElement('script'); script.type = 'text/javascript'; script.src = 'http://esv.to/media/js/bookmarklet.js'; body.appendChild(script); void(0); The code from http://esv.to/media/js/bookmarklet.js looks like this: (function() { function shorten(ref, callback) { var url = "http://esv.to/api/" + escape(ref); var req = new XMLHttpRequest(); req.onreadystatechange = function shortenIt() { if ( this.readyState == 4 && this.status == 200 ) { callback(req.responseText); }; }; req.open( "GET", url ); req.send(); }; function doBookmarklet() { var ref = prompt("Enter a scripture reference or keyword search to link to:", "") shorten(ref, function (short) { prompt("Here is your shortened ESV URL:", short); }); }; doBookmarklet(); })(); When called from http://esv.to itself, the bookmarklet works correctly. But when used on another page, it does not. The strange thing is, when I watch the request from Firebug, the response is 200 OK, the browser downloads 17 bytes (the length of the returned string), but the response body is empty! No error is thrown, just an empty responseText on the XmlHttpRequest object. Now, according to http://stackoverflow.com/questions/664689/ajax-call-from-bookmarklet, GET shouldn't violate the same origin policy. Is this a bug? Is there a workaround?

  • How does memory management in Java and C# differ?

    - by David Johnstone
    I was reading through 2010 CWE/SANS Top 25 Most Dangerous Programming Errors and one of the entries is for Buffer Copy without Checking Size of Input. It suggests using a language with features to prevent or mitigate this problem, and says: For example, many languages that perform their own memory management, such as Java and Perl, are not subject to buffer overflows. Other languages, such as Ada and C#, typically provide overflow protection, but the protection can be disabled by the programmer. I was not aware that Java and C# differed in any meaningful way with regard to memory management. How is it that Java is not subject to buffer overflows, while C# only protects against overflows? And how is it possible to disable this protection in C#?

  • Clojure / HBase: How to Import HBaseTestingUtility in v0.94.6.1

    - by David Williams
    In Clojure, if I want to start a test cluster using the hbase testing utility, I have to annotate my dependencies with: [org.apache.hbase/hbase "0.92.2" :classifier "tests" :scope "test"] First of all, I have no idea what this means. According to leiningens sample project.clj ;; Dependencies are listed as [group-id/name version]; in addition ;; to keywords supported by Pomegranate, you can use :native-prefix ;; to specify a prefix. This prefix is used to extract natives in ;; jars that don't adhere to the default "<os>/<arch>/" layout that ;; Leiningen expects. Question 1: What does that mean? Question 2: If I upgrade the version: [org.apache.hbase/hbase "0.94.6.1" :classifier "tests" :scope "test"] Then I receive a ClassNotFoundException Exception in thread "main" java.lang.ClassNotFoundException: org.apache.hadoop.hbase.HBaseConfiguration Whats going on here and how do I fix it?

  • Passing Variable Length Arrays to a function

    - by David Bella
    I have a variable length array that I am trying to pass into a function. The function will shift the first value off and return it, and move the remaining values over to fill in the missing spot, putting, let's say, a -1 in the newly opened spot. I have no problem passing an array declared like so: int framelist[128]; shift(framelist); However, I would like to be able to use a VLA declared in this manner: int *framelist; framelist = malloc(size * sizeof(int)); shift(framelist); I can populate the arrays the same way outside the function call without issue, but as soon as I pass them into the shift function, the one declared in the first case works fine, but the one in the second case immediately gives a segmentation fault. Here is the code for the queue function, which doesn't do anything except try to grab the value from the first part of the array... int shift(int array[]) { int value = array[0]; return value; } Any ideas why it won't accept the VLA? I'm still new to C, so if I am doing something fundamentally wrong, let me know.

  • DataTable won't DataBind with a DataTable.NewRow()

    - by David
    Is DataRow.NewRow() insufficient as the only row in a DataTable? I would expect this to work, but it doesn't. It's near the end of my Page_Load inside my If(!Postback) block. gridCPCP is GridView DataTable dt = new DataTable(); dt.Columns.Add("ID", int.MinValue.GetType()); dt.Columns.Add("Code", string.Empty.GetType()); dt.Columns.Add("Date", DateTime.MinValue.GetType()); dt.Columns.Add("Date2", DateTime.MinValue.GetType()); dt.Columns.Add("Filename", string.Empty.GetType()); //code to add rows if (dt.Rows.Count > 0) { gridCPCP.DataSource = dt; gridCPCP.DataBind(); } else { dt.Rows.Add(dt.NewRow()); gridCPCP.DataSource = dt; gridCPCP.DataBind(); //EXCEPTION int TotalColumns = gridCPCP.Rows[0].Cells.Count; gridCPCP.Rows[0].Cells.Clear(); gridCPCP.Rows[0].Cells.Add(new TableCell()); gridCPCP.Rows[0].Cells[0].ColumnSpan = TotalColumns; gridCPCP.Rows[0].Cells[0].Text = "No Record Found"; } The exception throws on gridCPCP.DataBind() and only when execution reaches the else block. If there were rows added above via dt.Rows.Add(new object[] { ... } binding works. System.ArgumentOutOfRangeException: Length cannot be less than zero. Parameter name: length

  • ASP.NET The underlying connection was closed: Could not establish trust relat

    - by David Lively
    When attempting to use HttpWebRequest to retrieve a page from my dev server, I get a web exception: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel." The remote certificate is invalid according to the validation procedure... The url I'm attempting to read from is a plain-old http://myserver.com/mypage.asp - no SSL. The production server has a valid certificate so this shouldn't be an issue, but our dev server doesn't. Help!

  • Modifying my website to allow anonymous comments

    - by David
    I write the code for my own website as an educational/fun exercise. Right now part of the website is a blog (like every other site out there :-/) which supports the usual basic blog features, including commenting on posts. But I only have comments enabled for logged-in users; I want to alter the code to allow anonymous comments - that is, I want to allow people to post comments without first creating a user account on my site, although there will still be some sort of authentication involved to prevent spam. Question: what information should I save for anonymous comments? I'm thinking at least display name and email address (for displaying a Gravatar), and probably website URL because I eventually want to accept OpenID as well, but would anything else make sense? Other question: how should I modify the database to store this information? The schema I have for the comment table is currently comment_id smallint(5) // The unique comment ID post_id smallint(5) // The ID of the post the comment was made on user_id smallint(5) // The ID of the user account who made the comment comment_subject varchar(128) comment_date timestamp comment_text text Should I add additional fields for name, email address, etc. to the comment table? (seems like a bad idea) Create a new "anonymous users" table? (and if so, how to keep anonymous user ids from conflicting with regular user ids) Or create fake user accounts for anonymous users in my existing users table? Part of what's making this tricky is that if someone tries to post an anonymous comment using an email address (or OpenID) that's already associated with an account on my site, I'd like to catch that and prompt them to log in.

  • Where to start when programming process synchronization algorithms like clone/fork, semaphores

    - by David
    I am writing a program that simulates process synchronization. I am trying to implement the fork and semaphore techniques in C++, but am having trouble starting off. Do I just create a process and send it to fork from the very beginning? Is the program just going to be one infinite loop that goes back and forth between parent/child processes? And how do you create the idea of 'shared memory' in C++, explicit memory address or just some global variable? I just need to get the overall structure/idea of the flow of the program. Any references would be appreciated.

  • Adding LegendItems in Flex places horizontally not vertically (as it's supposed to)

    - by David
    I'm dynamically inserting LegendItems into a Legend using the following code: signalLegend.removeAllChildren(); signalLegend.direction = "vertical"; for (var i:int = 0; i < numItems - 1; i++) { signalLegend.addChild(new LegendItem()); legendItem = signalLegend.getChildAt(i) as LegendItem; legendItem.label = "Title here"; legendItem.setStyle("fill", theColour); } While the Legend direction is set as vertical, all the items are appearing horizontally. Very annoying.

  • MS-Access nested DIR - check if a file exists elsewhere whilst looping through a folder

    - by David Carle
    I have used the DIR() command in Microsoft Access 2003 to loop through the files in folder A. This works fine, but I need to check if each file also exists in another location (folder B), and only process the file if it doesn't exist in folder B. The problem is that checking for the file existing in folder B also uses the DIR() function and this then resets or confuses the original one, with the result that no further files are found in folder A. Is there a way to check if a file exists without using DIR? Or, is there a way to have a separate instance of DIR? I suppose I could build a list of the files in folder A into an array and then process the entries in the array, but this seems rather 'clunky' Any suggestions for a better solution? Thanks

  • C++ Array Initialization in Function Call or Constructor Call

    - by david
    This question is related to the post here. Is it possible to initialize an array in a function call or constructor call? For example, class foo's constructor wants an array of size 3, so I want to call foo( { 0, 0, 0 } ). I've tried this, and it does not work. I'd like to be able to initialize objects of type foo in other objects' constructor initialization lists, or initialize foo's without first creating a separate array. Is this possible?

  • rails routes for permalink with namespaced class

    - by David
    this one in my routes works perfectly: map.connect ':permalink', :controller = 'pages', :action = 'show' for this class: class PagesController < BackendController and on /xxx/pages it is shown like this: <%= link_to "#{item.link_name}", {:controller = :pages, :action = :show, :permalink = item.permalink} % which will generate a link like "how-to-create-permalinks". but i decided to move the PagesController into a subdirectory so the class is now written like so: class Backend::PagesController < BackendController But how does the route look like now? And how do i display it on the template so it links using the permalink? Thanks!

  • Applying the Hibernate filter attribute to a Bag with a many-to-many relationship

    - by David P
    Consider the following Hibernate mapping file: <hibernate-mapping ...> <class name="ContentPackage" table="contentPackages"> <id name="Id" column="id" type="int"><generator class="native" /></id> ... <bag name="Clips" table="contentAudVidLinks"> <key column="fk_contentPackageId"></key> <many-to-many class="Clip" column="fk_AudVidId"></many-to-many> <filter name="effectiveDate" condition=":asOfDate BETWEEN startDate and endDate" /> </bag> </class> </hibernate-mapping> When I run the following command: _session.EnableFilter("effectiveDate").SetParameter("asOfDate", DateTime.Today); IList<ContentPackage> items = _session.CreateCriteria(typeof(ContentPackage)) .Add(Restrictions.Eq("Id", id)) .List<ContentPackage>(); The resulting SQL has the WHERE clause on the intermediate mapping table (contentAudVidLinks), rather than the "Clips" table even though I have added the filter attribute to the Bag of Clips. What am I doing wrong?

  • NSZombieEnabled hides EXC_BAD_ACCESS error entirely

    - by David Liu
    So I have a subclass of a UIView that starts causing EXC_BAD_ACCESS errors when I go through a specific set of conditions (run on iPad instead of iPhone or simulator, first login only). It throws the exception when the UIView subclass gets deallocated, during the last line, where I have [super dealloc]. I heard about using NSZombieEnabled, so I tossed that on to see if I could get any more information about it, but now it hides the error completely! Does anyone know a bit more about this type of situation? I thought NSZombie would start spewing stuff into my console like before, but I'm hoping that the nonexistance of errors would tell me some sort of information as well.

  • SQL query to get latest record for all distinct items in a table

    - by David Buckley
    I have a table of all sales defined like: mysql> describe saledata; +-------------------+---------------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------------------+---------------------+------+-----+---------+-------+ | SaleDate | datetime | NO | | NULL | | | StoreID | bigint(20) unsigned | NO | | NULL | | | Quantity | int(10) unsigned | NO | | NULL | | | Price | decimal(19,4) | NO | | NULL | | | ItemID | bigint(20) unsigned | NO | | NULL | | +-------------------+---------------------+------+-----+---------+-------+ I need to get the last sale price for all items (as the price may change). I know I can run a query like: SELECT price FROM saledata WHERE itemID = 1234 AND storeID = 111 ORDER BY saledate DESC LIMIT 1 However, I want to be able to get the last sale price for all items (the ItemIDs are stored in a separate item table) and insert them into a separate table. How can I get this data? I've tried queries like this: SELECT storeID, itemID, price FROM saledata WHERE itemID IN (SELECT itemID from itemmap) ORDER BY saledate DESC LIMIT 1 and then wrap that into an insert, but it's not getting the proper data. Is there one query I can run to get the last price for each item and insert that into a table defined like: mysql> describe lastsale; +-------------------+---------------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------------------+---------------------+------+-----+---------+-------+ | StoreID | bigint(20) unsigned | NO | | NULL | | | Price | decimal(19,4) | NO | | NULL | | | ItemID | bigint(20) unsigned | NO | | NULL | | +-------------------+---------------------+------+-----+---------+-------+

  • Parsing Complex Text File with C#

    - by David
    Hello, I need to parse a text file that has a lot of levels and characters. I've been trying different ways to parse it but I haven't been able to get anything to work. I've included a sample of the text file I'm dealing with. Any suggestions on how I can parse this file? I have denoted the parts of the file I need with TEXTINEED. (bean name: 'TEXTINEED context: (list '/text '/content/home/left-nav/text '/content/home/landing-page) type: '/text/types/text module: '/modules/TEXTINEED source: '|moretext| ((contents (list (list (bean type: '/directory/TEXTINEED ((directives (bean ((chartSize (list 600 400)) (showCorners (list #f)) (showColHeader (list #f)) (showRowHeader (list #f))))))) (bean type: '/directory/TEXTINEED ((directives (bean ((displayName (list "MTD")) (showCorners (list #f)) (showColHeader (list #f)) (showRowLabels (list #f)) (hideDetailedLink (list #t)) (showRowHeader (list #f)) (chartSize (list 600 400))))))) (bean type: '/directory/TEXTINEED ((directives (bean ((displayName (list "QTD")) (showCorners (list #f)) (showColHeader (list #f)) (showRowLabels (list #f)) (hideDetailedLink (list #t)) (showRowHeader (list #f)) (chartSize (list 600 400)))))))) Thanks!

  • Testing objects for changes

    - by David Veeneman
    I have an application that needs to determine whether a user has made a change to an object. So, when the object is first loaded, I create a deep copy (using serialization/deserialization) and save the copy to a separate field. The copy becomes myCurrentObject, and the original becomes myOriginalObject. Now I need to test myCurrentObject for changes, which I plan to do by comparing it to myOriginalObject. All I need is a boolean result indicating whether any changes have been made. I have already determined that a simple hashcode comparison won't work. GetHashCode() generates different results for the two objects, even when there are no changes. I am getting ready to write a method to do a property-by-property comparison, but before I do, I thought I would check to see if there is a simpler and more reusable way to test myCurrentObject to see if it has changed from myOriginalObject. Any suggestions? Thanks for your help.

  • Trouble getting $.ajax() to work in PhoneGap against a locally hosted server

    - by David Gutierrez
    Currently trying to make an ajax post request to an IIS Express hosted MVC 4 Web API end point from an android VM (Bluestacks) on my machine. Here are the snippets of code that I am trying, and cannot get to work: $.ajax({ type: "POST", url: "http://10.0.2.2:28434/api/devices", data: {'EncryptedPassword':'1234','UserName':'test','DeviceToken':'d234'} }).always(function( data, textStatus, jqXHR ) { alert( textStatus ); }); Whenever I run this request I always get back a textStatus of 'error'. After hours of trying different things, I pushed my End Point to an actual server, and was able to actually get responses back in PhoneGap if I built up an XMLHttpRequest by hand, like so: var request = new XMLHttpRequest(); request.open("POST", "http://172.16.100.42/MobileRewards/api/devices", true); request.onreadystatechange = function(){//Call a function when the state changes. console.log("state = " + request.readyState); console.log("status = " + request.status); if (request.readyState == 4) { if (request.status == 200 || request.status == 0) { console.log("*" + request.responseText + "*"); } } } request.send("{EncryptedPassword:1234,UserName:test,DeviceToken:d234}"); Unfortunately, if I try to use $.ajax() against the same end point in the snippet above I still get a status text that says 'error', here is that snippet for reference: $.ajax({ type: "POST", url: "http://172.16.100.42/MobileRewards/api/devices", data: {'EncryptedPassword':'1234','UserName':'test','DeviceToken':'d234'} }).always(function( data, textStatus, jqXHR ) { alert( textStatus ); }); So really, there are a couple of questions here. 1) Why can't I get any ajax calls (post or get) to successfully hit my End Point when it's hosted via IIS Express on the same machine that the Android VM is running? 2) When my end point is hosted on an actual server, through IIS and served through port 80, why can't I get post requests to be successful when I use jquery's ajax calls? (Even though I can get it to work by manually creating an XMLHttpRequest) Thanks
