• How to execute PHPUnit?

  - by user1280667

  PHPUnit can execute script like this: phpunit --log-junit classname filename.php (i need the XML report , for my continus integreation platform) but my problem is that i work with a MVC framework and all pages are called through pathofproject/indexCLI.php module=moduleName class=className ect with 3 arguments in total(when i use the shell commande and path/index.php argum=... with url) so i cant call phpunit pathofproject/indexCLI.php module=moduleName class=className . So i think to a lot of solution , i hope you can help me to use one of them. first how can i use phpunit commande with this type of calling, because i cant do it because he is waiting a classname and a filename (default comportement) if it possible !! when i call the same link in shell like this : php path/indexCLI.php module="blabla" ect ... i have the result of assertion in my consol , but cant use XML Junit option , can i do it ? my last solution is to call the link in a navigator like mozzila , but i dont know how to say to phpunit runner to chose XML report and not HTML report. the aim for me , is to have a XML report .

• Memory Leak Looping cfmodule inside cffunction

  - by orangepips

  Hoping someone else can confirm or tell me what I'm doing wrong. I am able to consistently reproduce an OOM running by calling the file oom.cfm (shown below). Using jconsole I am able to see the request consumes memory and never releases it until complete. The issue appears to be calling <cfmodule> inside of <cffunction>, where if I comment out the <cfmodule> call things are garbage collected while the request is running.

• Reading a Wordpress function description

  - by Casebash

  I want to be able to understand the standard function description that is provided for Wordpress functions. In particular, could someone explain the following example from here: Usage <?php wp_list_categories( $args ); ?> Default Usage <?php $args = array( 'show_option_all' => , 'orderby' => 'name', 'order' => 'ASC', 'show_last_update' => 0, 'style' => 'list', 'show_count' => 0, 'hide_empty' => 1, 'use_desc_for_title' => 1, 'child_of' => 0, 'feed' => , 'feed_type' => , 'feed_image' => , 'exclude' => , 'exclude_tree' => , 'include' => , 'current_category' => 0, 'hierarchical' => true, 'title_li' => __( 'Categories' ), 'number' => NULL, 'echo' => 1, 'depth' => 0 ); ?> I can guess most of it, but in particular I can't guess: What does blank after the comma mean? Empty string? What is the __? How do I call the function? Keyword like python, positional arguments or do I have to pass an array? Is there anything else about Wordpress function descriptions which isn't covered in this example? Thanks, Chris

• Using LINQ on observable with GroupBy and Sum aggregate

  - by Mark Oates

  I have the following block of code which works fine; var boughtItemsToday = (from DBControl.MoneySpent bought in BoughtItemDB.BoughtItems select bought); BoughtItems = new ObservableCollection<DBControl.MoneySpent>(boughtItemsToday); It returns data from my MoneySpent table which includes ItemCategory, ItemAmount, ItemDateTime. I want to change it to group by ItemCategory and ItemAmount so I can see where I am spending most of my money, so I created a GroupBy query, and ended up with this; var finalQuery = boughtItemsToday.AsQueryable().GroupBy(category => category.ItemCategory); BoughtItems = new ObservableCollection<DBControl.MoneySpent>(finalQuery); Which gives me 2 errors; Error 1 The best overloaded method match for 'System.Collections.ObjectModel.ObservableCollection.ObservableCollection(System.Collections.Generic.List)' has some invalid arguments Error 2 Argument 1: cannot convert from 'System.Linq.IQueryable' to 'System.Collections.Generic.List' And this is where I'm stuck! How can I use the GroupBy and Sum aggregate function to get a list of my categories and the associated spend in 1 LINQ query?! Any help/suggestions gratefully received. Mark

• Why does one of these statements compile in Scala but not the other?

  - by Jeff

  (Note: I'm using Scala 2.7.7 here, not 2.8). I'm doing something pretty simple -- creating a map based on the values in a simple, 2-column CSV file -- and I've completed it easily enough, but I'm perplexed at why my first attempt didn't compile. Here's the code: // Returns Iterator[String] private def getLines = Source.fromFile(csvFilePath).getLines // This doesn't compile: def mapping: Map[String,String] = { Map(getLines map { line: String => val pairArr = line.split(",") pairArr(0) -> pairArr(1).trim() }.toList:_*) } // This DOES compile def mapping: Map[String,String] = { def strPair(line: String): (String,String) = { val pairArr = line.split(",") pairArr(0) -> pairArr(1).trim() } Map(getLines.map( strPair(_) ).toList:_*) } The compiler error is CsvReader.scala:16: error: value toList is not a member of (St ring) = (java.lang.String, java.lang.String) [scalac] possible cause: maybe a semicolon is missing before `value toList'? [scalac] }.toList:_*) [scalac] ^ [scalac] one error found So what gives? They seem like they should be equivalent to me, apart from the explicit function definition (vs. anonymous in the nonworking example) and () vs. {}. If I replace the curly braces with parentheses in the nonworking example, the error is "';' expected, but 'val' found." But if I remove the local variable definition and split the string twice AND use parens instead of curly braces, it compiles. Can someone explain this difference to me, preferably with a link to Scala docs explaining the difference between parens and curly braces when used to surround method arguments?

• How can I automatically elevate a COM interface used for automation?

  - by Jim Flood

  I have a Windows service built with ATL to expose a LocalServer32 COM interface for a set of admin commands used for configuring the service, and these can be used from VBScript for example: Set myObj = WScript.CreateObject("MySvc.Administrator") myObj.DoSomething() I want DoSomething to run elevated, and I would like the UAC prompt to come up automatically when this is called by the VBScript. Is this possible? I know I can run the script in an elevated command shell, and that I can use objShell.ShellExecute WScript.FullName, Chr(34) & WScript.ScriptFullName & Chr(34), vbNullString, "runas" for example, to run the VBScript itself elevated, and either of those work fine -- the COM method finds itself elevated. However, AFAIK getting an elevated Explorer window on the desktop is convoluted (it's not as simple as right-clicking Start/Accessories/Windows Explorer/Run as Administrator, which doesn't actually elevate.) I want a user in the local admin group to be able to drag-and-drop files and folders onto the script, and then have the script call the admin COM interface with those pathnames as arguments. (And I am hoping for something simpler than monkeying around with the args and using ShellExecute "runas".) I've tried setting UAC Execution Level to requireAdministrator in the service EXE's manifest, and setting Elevated/Enabled = 1 and LocalizedString in the registry for the MySvc.Administrator class, and these don't do the trick.

• BWToolkit inclusion crashing

  - by Schroedinger

  Hey guys I'm using the latest version of XCode (3.2.2) and I've linked the framework using the tutorial. I was building my app and tested it and I get a BWToolkit exception on decoding. I've included the Framework in the frameworks and added it to the copy files stage. I even created a new dummy app including the framework and adding it to the copy files stage and it still crashes when I try to run. Any ideas? Do I need to include it somewhere in the app? I'm worried I've overlooked something really simple. 2010-04-13 14:14:24.540 BWTestFramework[7504:a0f] An uncaught exception was raised 2010-04-13 14:14:24.543 BWTestFramework[7504:a0f] *** -[NSKeyedUnarchiver decodeObjectForKey:]: cannot decode object of class (BWSplitView) 2010-04-13 14:14:24.545 BWTestFramework[7504:a0f] *** Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: '*** -[NSKeyedUnarchiver decodeObjectForKey:]: cannot decode object of class (BWSplitView)' *** Call stack at first throw: ( 0 CoreFoundation 0x00007fff84a77d24 __exceptionPreprocess + 180 1 libobjc.A.dylib 0x00007fff82ba00f3 objc_exception_throw + 45 2 CoreFoundation 0x00007fff84a77b47 +[NSException raise:format:arguments:] + 103 3 CoreFoundation 0x00007fff84a77ad4 +[NSException raise:format:] + 148 4 Foundation 0x00007fff83804aa6 _decodeObjectBinary + 2427 5 Foundation 0x00007fff83805825 -[NSKeyedUnarchiver _decodeArrayOfObjectsForKey:] + 1229 6 Foundation 0x00007fff83805d65 -[NSArray(NSArray) initWithCoder:] + 462 7 Foundation 0x00007fff83804b1f _decodeObjectBinary + 2548 8 Foundation 0x00007fff83803f99 _decodeObject + 208 9 AppKit 0x00007fff8069fbfb -[NSView initWithCoder:] + 362 10 Foundation 0x00007fff83804b1f _decodeObjectBinary + 2548 11 Foundation 0x00007fff83803f99 _decodeObject + 208 12 AppKit 0x00007fff806adfbb -[NSWindowTemplate initWithCoder:] + 3824 13 Foundation 0x00007fff83804b1f _decodeObjectBinary + 2548 14 Foundation 0x00007fff83805825 -[NSKeyedUnarchiver _decodeArrayOfObjectsForKey:] + 1229 15 Foundation 0x00007fff83805268 -[NSSet(NSSet) initWithCoder:] + 447 16 Foundation 0x00007fff83804b1f _decodeObjectBinary + 2548 17 Foundation 0x00007fff83803f99 _decodeObject + 208 18 AppKit 0x00007fff8062fcde -[NSIBObjectData initWithCoder:] + 1983 19 Foundation 0x00007fff83804b1f _decodeObjectBinary + 2548 20 Foundation 0x00007fff83803f99 _decodeObject + 208 21 AppKit 0x00007fff8062f40d loadNib + 146 22 AppKit 0x00007fff8062e96d +[NSBundle(NSNibLoading) _loadNibFile:nameTable:withZone:ownerBundle:] + 248 23 AppKit 0x00007fff8062e7a5 +[NSBundle(NSNibLoading) loadNibNamed:owner:] + 326 24 AppKit 0x00007fff8062bd27 NSApplicationMain + 279 25 BWTestFramework 0x0000000100001891 main + 33 26 BWTestFramework 0x0000000100001868 start + 52 ) terminate called after throwing an instance of 'NSException' That's the crash report

• How to optimize an asp.net spawning a new process for each request ?

  - by Recycle Bin

  I have an asp.net mvc application that spawns a Process as follows: Process p = new Process(); p.EnableRaisingEvents = true; p.Exited += new EventHandler(p_Exited); p.StartInfo.Arguments = "-interaction=nonstopmode " + inputpath; p.StartInfo.WorkingDirectory = dir; p.StartInfo.UseShellExecute = false; p.StartInfo.FileName = "pdflatex.exe"; p.StartInfo.LoadUserProfile = true; p.Start(); p.WaitForExit(); Before going further, I need to know whether, e.g., pdflatex.exe is a managed code or a native code? Edit I need to consider this because: (Hopely I am not wrong...) Each Asp.net application runs in an separate/isolated AppDomain as opposed to a separate/isolated process. A native executable cannot live in an AppDomain. to be continued... Shortly speaking, I hope my site does not spawn a new process for each request. Because a process is more expensive than an application domain.

• BeginInvoke on ObservableCollection not immediate.

  - by Padu Merloti

  In my code I subscribe to an event that happens on a different thread. Every time this event happens, I receive an string that is posted to the observable collection: Dispatcher currentDispatcher = Dispatcher.CurrentDispatcher; var SerialLog = new ObservableCollection<string>(); private void hitStation_RawCommandSent(object sender, StringEventArgs e) { string command = e.Value.Replace("\r\n", ""); Action dispatchAction = () => SerialLog.Add(command); currentDispatcher.BeginInvoke(dispatchAction, DispatcherPriority.Render); } The code below is in my view model (could be in the code behind, it doesn't matter in this case). When I call "hitstation.PrepareHit", the event above gets called a couple times, then I wait and call "hitStation.HitBall", and the event above gets called a couple more times. private void HitBall() { try { try { Mouse.OverrideCursor = Cursors.Wait; //prepare hit hitStation.PrepareHit(hitSpeed); Thread.Wait(1000); PlayWarning(); //hit hitStation.HitBall(hitSpeed); } catch (TimeoutException ex) { MessageBox.Show("Timeout hitting ball: " + ex.Message); } } finally { Mouse.OverrideCursor = null; } } The problem I'm having is that the ListBox that is bound to my SerialLog gets updated only when the HitBall method finishes. I was expecting seeing a bunch of updates from the PrepareHit, a pause and then a bunch more updates from the HitBall. I've tried a couple of DispatcherPriority arguments, but they don't seem to have any effect.

• How to update a property using Type.GetProperties() method?

  - by Richard77

  Hello, I've a collection of a class' properties and would like to update each one's value by iterating over the collection through the index. 1) I create the collection of properties this way private PropertyInfo[] GetPropertiesOfMyClass() { Type myType = (typeof(myClass)); PropertyInfo[] PropertyInfoArray = myType.GetProperties( BindingFlags.Public | BindingFlags.Instance); return PropertyInfoArray; } 2)Now, I'd like to set up the value of each one depending on the index this way public void UpdateProperty(MyClass instanceOfMyClass, string valueToUpdate, int index) { //TODO: //1. Get an individual property from the GetPropertyOfMyClass() using index //2. Update the value of an individual property of the instanceOfMyClass } I'd like to be able to call UpdateProperty from a Controller like this: UpdateProperty(instanceOfMyClass, valueToUpdate, indexOfTheProperty); Honestly, I do not know how to involve the instanceOfMyClass in the game as GetProperty only plays with myClass. Since I saw that I can use Name, PropertyType, ... to get information on the property. So, I've tried also GetPropertyOfMyClass()[index].SetValue(...), but I was lost in the arguments of its constructor, so I abandoned. What I want is to be able to update the value of a property in my collection just by using the index. Thanks for helping

• Debugging Actionmailer

  - by Trip

  I have actionmailer set up. Emails are not being sent, and no errors. Where can I start my search to debug this? class Notifier < ActionMailer::Base default_url_options[:host] = APP_DOMAIN def email_blast(user, subject, message) subject subject from NOTIFIER_EMAIL recipients user.email sent_on Time.zone.now body :user => user.first_name + ' ' + user.last_name, :message => message end I do get a return in my log that the email was sent, just no actual email goes through. Also the reason, that this is not working is because I switched form a cluster to a solo box and some server settings were overwritten. I suspect that is probably the reason why this is not working. Anyone know what specific server settings I would have to look at ? UPDATE: ActionMailer::Base.delivery_method = :sendmail config.action_mailer.default_url_options = { :host => "75.101.153.93" } I found this in my production.rb . This code was originally here when it worked. Again, I believe that there must be something missing on my server..I did a 'which sendmail' and it returned /usr/bin/sendmail , so I added this : config.action_mailer.raise_delivery_errors = false config.action_mailer.perform_deliveries = true config.action_mailer.sendmail_settings = { :location => '/usr/bin/sendmail', :arguments => '-i -t' } Redeployed, restarted the server, and tested it. No emails were sent. The production.log said something was sent : Processing MediaController#create_a_video (for 173.161.167.41 at 2010-06-03 11:58:13) [GET] Parameters: {"action"=>"create_a_video", "controller"=>"media", "organization_id"=>"470", "_"=>"1275591493194"} Sent mail to [email protected] Rendering media/create_a_video Completed in 128ms (View: 51, DB: 1) | 200 OK [http://invent.hqchannel.com/organizations/470/media/create_a_video?_=1275591493194]

• Moving inserted container element if possible

  - by doublep

  I'm trying to achieve the following optimization in my container library: when inserting an lvalue-referenced element, copy it to internal storage; but when inserting rvalue-referenced element, move it if supported. The optimization is supposed to be useful e.g. if contained element type is something like std::vector, where moving if possible would give substantial speedup. However, so far I was unable to devise any working scheme for this. My container is quite complicated, so I can't just duplicate insert() code several times: it is large. I want to keep all "real" code in some inner helper, say do_insert() (may be templated) and various insert()-like functions would just call that with different arguments. My best bet code for this (a prototype, of course, without doing anything real): #include <iostream> #include <utility> struct element { element () { }; element (element&&) { std::cerr << "moving\n"; } }; struct container { void insert (const element& value) { do_insert (value); } void insert (element&& value) { do_insert (std::move (value)); } private: template <typename Arg> void do_insert (Arg arg) { element x (arg); } }; int main () { { // Shouldn't move. container c; element x; c.insert (x); } { // Should move. container c; c.insert (element ()); } } However, this doesn't work at least with GCC 4.4 and 4.5: it never prints "moving" on stderr. Or is what I want impossible to achieve and that's why emplace()-like functions exist in the first place?

• Possible to rank partial matches in Postgres full text search?

  - by Joe

  I'm trying to calculate a ts_rank for a full-text match where some of the terms in the query may not be in the ts_vector against which it is being matched. I would like the rank to be higher in a match where more words match. Seems pretty simple? Because not all of the terms have to match, I have to | the operands, to give a query such as to_tsquery('one|two|three') (if it was &, all would have to match). The problem is, the rank value seems to be the same no matter how many words match. In other words, it's maxing rather than multiplying the clauses. select ts_rank('one two three'::tsvector, to_tsquery('one')); gives 0.0607927. select ts_rank('one two three'::tsvector, to_tsquery('one|two|three|four')); gives the expected lower value of 0.0455945 because 'four' is not the vector. But select ts_rank('one two three'::tsvector, to_tsquery('one|two')); gives 0.0607927 and likewise select ts_rank('one two three'::tsvector, to_tsquery('one|two|three')); gives 0.0607927 I would like the result of ts_rank to be higher if more terms match. Possible? To counter one possible response: I cannot calculate all possible subsequences of the search query as intersections and then union them all in a query because I am going to be working with large queries. I'm sure there are plenty of arguments against this anyway! Edit: I'm aware of ts_rank_cd but it does not solve the above problem.

• Safe to pass objects to C functions when working in JNI Invocation API?

  - by bubbadoughball

  I am coding up something using the JNI Invocation API. A C program starts up a JVM and makes calls into it. The JNIenv pointer is global to the C file. I have numerous C functions which need to perform the same operation on a given class of jobject. So I wrote helper functions which take a jobject and process it, returning the needed data (a C data type...for example, an int status value). Is it safe to write C helper functions and pass jobjects to them as arguments? i.e. (a simple example - designed to illustrate the question): int getStatusValue(jobject jStatus) { return (*jenv)->CallIntMethod(jenv,jStatus,statusMethod); } int function1() { int status; jobject aObj = (*jenv)->NewObject (jenv, aDefinedClass, aDefinedCtor); jobject j = (*jenv)->CallObjectMethod (jenv, aObj, aDefinedObjGetMethod) status = getStatusValue(j); (*jenv)->DeleteLocalRef(jenv,aObj); (*jenv)->DeleteLocalRef(jenv,j); return status; } Thanks.

• How do I grab and use a variables coming back through ValueList from an AJAX call?

  - by Mel

  I'm trying the following code to execute a search and it's not working. On the search.cfm page, the only value coming back is the value I input into the search field (even if I click an autosuggest value, it's not coming back; only the letters I actually type myself come back). <cfform class="titleSearchForm" id="searchForm" action="search.cfm?GameID=#cfautosuggestvalue.GameID#" method="post"> <fieldset> <cfinput type="text" class="titleSearchField" name="TitleName" onChange="form.submit()" autosuggest="cfc:gz.cfcomp.search.AutoSuggestSearch({cfautosuggestvalue})"> <input type="button" class="titleSearchButton" value=" " /> </fieldset> </cfform> Query in CFC: <cfquery name="SearchResult" datasource="myDSN"> SELECT CONCAT(titles.TitleName, ' on ', platforms.PlatformAbbreviation) AS sResult, games.GameID FROM games Inner Join platforms ON games.PlatformID = platforms.PlatformID Inner Join titles ON titles.TitleID = games.TitleID WHERE UCase(titleName) LIKE Ucase('#ARGUMENTS.SearchString#%') ORDER BY titleName ASC; </cfquery> Two things: First of all, I would like to get the GameID back to the page making the AJAX request; I know why it is not coming back: Because I'm only returning sResult var, which does not include the GameID. Is there a way to return the GameID value without displaying it? The second thing: How to I grab a value from the auto-suggest once it is returned? Say I want to grab the GameID, or if I can't do that, the "TitleName" to use that in my query? I tried passing it to the form this way: action="search.cfm?GameID=#cfautosuggestvalue.GameID#" - but that does not work. How do I reference the autosuggestionvalue varaibles for use? Thanks

• Swig C++ Lua Pass class by reference

  I don't know why I'm having a hard time with this. All I want to do is this: class foo { public: foo(){} ~foo(){} float a,b; }; class foo2 { public: foo2(){} foo2(const foo &f){*this = f;} ~foo2(){} void operator=(const foo& f){ x = f.a; y = f.b; } float x,y; }; /* Usage(cpp): foo f; foo2 f2(f); //or using the = operator f2 = f; */ The problem I'm having is that, after swigging this code, I can't figure out how to make the lua script play nice. /* Usage(lua) f = example.foo() f2 = example.foo2(f) --error */ The error I get is "Wrong arguments for overloaded function 'new_Foo2'": Possible c/c++ prototypes are: foo2() foo2(foo const &) The same thing happens if I try and use do f2 = f. As I understand it everything is stored as a pointer so I did try adding an additional constructor that took a pointer to foo but to no avail.

• Why does GCC need extra declarations in templates when VS does not?

  - by Kyle

  template<typename T> class Base { protected: Base() {} T& get() { return t; } T t; }; template<typename T> class Derived : public Base<T> { public: Base<T>::get; // Line A Base<T>::t; // Line B void foo() { t = 4; get(); } }; int main() { return 0; } If I comment out lines A and B, this code compiles fine under Visual Studio 2008. Yet when I compile under GCC 4.1 with lines A and B commented, I get these errors: In member function ‘void TemplateDerived::foo()’: error: ‘t’ was not declared in this scope error: there are no arguments to ‘get’ that depend on a template parameter, so a declaration of ‘get’ must be available Why would one compiler require lines A and B while the other doesn't? Is there a way to simplify this? In other words, if derived classes use 20 things from the base class, I have to put 20 lines of declarations for every class deriving from Base! Is there a way around this that doesn't require so many declarations?

• Why do case class companion objects extend FunctionN?

  When you create a case class, the compiler creates a corresponding companion object with a few of the case class goodies: an apply factory method matching the primary constructor, equals, hashCode, and copy. Somewhat oddly, this generated object extends FunctionN. scala> case class A(a: Int) defined class A scala> A: (Int => A) res0: (Int) => A = <function1> This is only the case if: There is no manually defined companion object There is exactly one parameter list There are no type arguments The case class isn't abstract. Seems like this was added about two years ago. The latest incarnation is here. Does anyone use this, or know why it was added? It increases the size of the generated bytecode a little with static forwarder methods, and shows up in the #toString() method of the companion objects: scala> case class A() defined class A scala> A.toString res12: java.lang.String = <function0>

• Specializing a class template constructor

  - by SilverSun

  I'm messing around with template specialization and I ran into a problem with trying to specialize the constructor based on what policy is used. Here is the code I am trying to get to work. #include <cstdlib> #include <ctime> class DiePolicies { public: class RollOnConstruction { }; class CallMethod { }; }; #include <boost/static_assert.hpp> #include <boost/type_traits/is_same.hpp> template<unsigned sides = 6, typename RollPolicy = DiePolicies::RollOnConstruction> class Die { // policy type check BOOST_STATIC_ASSERT(( boost::is_same<RollPolicy, DiePolicies::RollOnConstruction>::value || boost::is_same<RollPolicy, DiePolicies::CallMethod>::value )); unsigned m_die; unsigned random() { return rand() % sides; } public: Die(); void roll() { m_die = random(); } operator unsigned () { return m_die + 1; } }; template<unsigned sides> Die<sides, DiePolicies::RollOnConstruction>::Die() : m_die(random()) { } template<unsigned sides> Die<sides, DiePolicies::CallMethod>::Die() : m_die(0) { } ...\main.cpp(29): error C3860: template argument list following class template name must list parameters in the order used in template parameter list ...\main.cpp(29): error C2976: 'Die' : too few template arguments ...\main.cpp(31): error C3860: template argument list following class template name must list parameters in the order used in template parameter list Those are the errors I get in Microsoft Visual Studio 2010. I'm thinking either I can't figure out the right syntax for the specialization, or maybe it isn't possible to do it this way.

• handle large Parcelable ArrayList in Android

  - by Gal Ben-Haim

  I'm developing an Android app that is a client to a JSON webservice API. I have classes of resource objects (some are nested) and I pass results from an IntentService that access the webserive using the Parcelable interface for all the resource classes. the webservice returns arrays or results that can be potentially large (because of the nesting, for example, a post object also contains comments array, each comment also contains a user object). currently I'm either inserting the results into a SQlite database or displaying them in a ListView. (my relevant methods are accepting ArrayList<resourceClass> as arguments). (some data need to be persistent stored and some should not). since I don't know what size of lists I can handle this way without reaching the memory limits, is this a good practice ? is it a better idea to save the parsed JSON to a local file immediately and pass the file path to the ResultReceiver, then either insert to database from that file or display the data ? is there a better way to handle this ? btw - I'm parsing the JSON as a stream with Gson's Reader so there shouldn't be memory issues at that stage.

• How to get more detail from an exception?

  - by cusimar9

  I have a .NET 4.0 web application which implements an error handler within the Application_Error event of Global.asax. When an exception occurs this intercepts it and sends me an email including a variety of information like the logged in user, the page the error occurred on, the contents of the session etc. This is all great but there is some fundamental detail missing which I seem unable to locate. For instance, this is a subset of an error I would receive and the associated stack trace: Source: Telerik.Web.UI Message: Selection out of range Parameter name: value Stack trace: at Telerik.Web.UI.RadComboBox.PerformDataBinding(IEnumerable dataSource) at Telerik.Web.UI.RadComboBox.OnDataSourceViewSelectCallback(IEnumerable data) at System.Web.UI.DataSourceView.Select(DataSourceSelectArguments arguments, DataSourceViewSelectCallback callback) at Telerik.Web.UI.RadComboBox.OnDataBinding(EventArgs e) at Telerik.Web.UI.RadComboBox.PerformSelect() at System.Web.UI.WebControls.BaseDataBoundControl.DataBind() at Telerik.Web.UI.RadComboBox.DataBind() at System.Web.UI.WebControls.BaseDataBoundControl.EnsureDataBound() at Telerik.Web.UI.RadComboBox.OnPreRender(EventArgs e) at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) Now as lovely as this is I could do with knowing a) the name of the control and b) the value which caused the control to be 'out of range'. Any suggestions about how I could get this sort of information? I've run this in debug mode and the objects passed to Global.asax don't seem to hold any more detail that I can see.

• NSIS patching (multiple patches in one file)

  - by Owen

  I'm able to generate patch files from one version to another using NSIS' Vpatch. Let's say I have mydll.dll version 1, and I have a patch to update it to version 2. Then I have a new version again, thus I generate another patch to update it to version 3. What bothers me though is, what if user cancels updating to version 2 and so forth. Then my latest version let's say is version 20. User decides to update to version 20. Is there a way to generate a patch that's like accumulative in nature? whereas user can jump from version any old version to the newest version (i.e ver 3 to ver 20) without passing through the versions in between? I've read this line in vpatch's documentation --- "if you want to be able to upgrade version 1 and 2 to version 3, you can put a 1 3 and 2 3 patch in one file." But how do I that? What if I alread have like 30 versions. Does that mean I have to create a patch whose arguments are old files(versions 1-29) and new file(version20)? Any help would be appreciated. Thanks...

• Javascript: Uncaught exception: "too few args"

  - by Rosarch

  I think I must be making some really stupid mistake. I'm using the latest version of jQuery to write an AJAX app. function refreshGPAForTerm(term) { var meta_data = term.children('.' + TERM_META_DATA_CLASS); meta_data.children('.' + MEDIAN_GPA_CLASS).fadeOut('slow').remove(); meta_data.append(_getMedianGPAElem(term.data('GPA'))).hide().fadeIn('slow'); } function moveToTerm(original_course, helper, term) { var cloned_course = original_course.clone(true); term.data('credits', term.data('credits') + cloned_course.data('credits')); term.data('median_GPA', term.data('median_GPA') + cloned_course.data('credits') * cloned_course.data('GPA')); // error here refreshGPAForTerm(term); refreshCreditForTerm(term); original_course.addClass('already-scheduled'); original_course.draggable('disable'); cloned_course.appendTo(term).hide().fadeIn('slow').draggable(); } When refreshGPAForTerm(term) is called, Firebug displays: "Uncaught exception - Too few arguments". Stepping through in a debugger, the code then goes into jQuery. Why is this happening? What am I doing wrong?
