  • When calling a asmx service via jqeury, how to pass arguments?

    - by Blankman
    How can I pass my service endpoint parameters? (pagesize in this case) My .asmx service method looks like: [WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public List<Object> GetData(int pageSize) { } When I call this via jQuery like: $.ajax({ type: "POST", url: "test.asmx/test123", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", success: function(msg) { }, error: function(msg) { } });

  • C# : MS Chart : SeriesCollection -> InvalidCastException?

    - by HeinrichStack
    What is the correct way to get the Series of a char in PPT 2010. I tried PowerPoint.SeriesCollection mySeriesCollection = (PowerPoint.SeriesCollection) myChart.SeriesCollection(1); throws the following exception Exception Type: System.InvalidCastException Further, What is the correct call in C# to get the series of a chart ? If I try this way: PowerPoint.Series mySeries = (PowerPoint.Series)myChart.SeriesCollection.Item(1); I get the following compile error : error CS0119: 'Microsoft.Office.Interop.PowerPoint.Chart.SeriesCollection(object)' is a 'method', which is not valid in the given context

  • GAE Datastore: persisting referenced objects

    - by David
    Two "I'm sorries" to begin with: 1) I've looked for a solution (here, and elsewhere), and couldn't find the answer. 2) English is not my mother tongue, so I may have some typos and the sort - please ignore them. To the point: I am trying to persist Java objects to the GAE datastore. I am not sure as to how to persist object having ("non-trivial") referenced object. That is, assume I have the following. public class Father { String name; int age; Vector<Child> offsprings; //this is what I call "non-trivial" reference //ctor, getters, setters... } public class Child { String name; int age; Father father; //this is what I call "non-trivial" reference //ctor, getters, setters... } The name field is unique in each type domain, and is considered a Primary-Key. In order to persist the "trivial" (String, int) fields, all I need is to add the correct annotation. So far so good. However, I don't understand how should I persist the home-brewed (Child, Father) types referenced. Should I: Convert each such reference to hold the Primary-Key (a name String, in this example) instead of the "actual" object. So, Vector<Child> offsprings; becomes Vector<String> offspringsNames; ? If that is the case, how do I handle the object at run-time? Do I just query for the Primary-Key from Class.getName, to retrieve the refrenced objects? Convert each such reference to hold the actual Key provided to me by the Datastore upon the proper put() operation? So, Vector<Child> offsprings; becomes Vector<Key> offspringsHashKeys; ? I would very much appreciate all kinds of comments. I have read ALL the offical relevant GAE docs/example. Throughout, they always persist "trivial" references, natively supported by the Datastore (e.g. in the Guestbook example, only Strings, and Longs). Many thanks, David

  • interactive window to execute dos commands in visual studio

    - by Anirudh Goel
    Hi, I know using External Tools options i can run a batch script or a cmd prompt. But here is what i need to do I want to be able to call a dos prompt inside visual studio, which must be interactive. That way i won't be outside visual studio and can run all my dos commands in it. Is it possible? Or can i extend the command window and capture the commands which are typed and process them using my custom code? Thanks

  • Using memcpy in the STL

    - by wowus
    Why does C++'s vector class call copy constructors? Why doesn't it just memcpy the underlying data? Wouldn't that be a lot faster, and remove half of the need for move semantics? I can't imagine a use case where this would be worse, but then again, maybe it's just because I'm being quite unimaginative.

  • Is it possible to return as SiteMap as a JsonResult?

    - by Paul Suart
    I've got a very simple Action on my Controller that's attempting to return my XmlSiteMap as a JsonResult: public ActionResult Index() { var nodes = SiteMap.Provider.RootNode; return new JsonResult() { Data = nodes, JsonRequestBehavior = JsonRequestBehavior.AllowGet }; } However, when I call the Action, an InvalidOperationException is thrown: "A circular reference was detected while serializing an object of type 'System.Web.SiteMapNode'." Is there a way to Json serialize a SiteMap, or indeed any object that has children of the same type?

  • Turn Function or Stored Procedure Result into "live" Result for LINQ

    - by Alex
    Is it possible to turn result sets obtained in LINQ through a stored procedure or function call into a "live" set of objects of which I can retrieve Foreign Key related objects? If, for example, my stored procedure returns a set of rows (= LINQ objects) of type "Contact", then I can't seem to obtain Contact.BillingAddress (which is related by Foreign Key). Any idea how to make this work?

  • Recursion with an Array; can't get the right value to return

    - by Matt
    Recursive Solution: Not working! Explanation: An integer, time, is passed into the function. It's then used to provide an end to the FOR statement (counter<time). The IF section (time == 0) provides a base case where the recursion should terminate, returning 0. The ELSE section is where the recursive call occurs: total is a private variable defined in the header file, elsewhere. It's initialized to 0 in a constructor, elsewhere. The function calls itself, recursively, adding productsAndSales[time-1][0] to total, again, and again, until the base call. Then the total is returned, and printed out later. Well, that's what I hoped for anyway. What I imagined would happen is that I would add up all the values in this one column of the array and the value would get returned, and printed out. Instead if returns 0. If I set the IF section to "return 1", I noticed that it returns powers of 2, for whatever value time is. EG: Time = 3, it returns 2*2 + 1. If time = 5, it returns 2*2*2*2 + 1. I don't understand why it's not returning the value I'm expecting. int CompanySales::calcTotals( int time ) { cout << setw( 4 ); if ( time == 0 ) { return 0; } else { return total += calcTotals( productsAndSales[ time-1 ][ 0 ]); } } Iterative Solution: Working! Explanation: An integer, time, is passed into the function. It's then used to provide an end to the FOR statement (counter<time). The FOR statement cycles through an array, adding all of the values in one column together. The value is then returned (and elsewhere in the program, printed out). Works perfectly. int CompanySales::calcTotals( int time ) { int total = 0; cout << setw( 4 ); for ( int counter = 0; counter < time; counter++ ) { total += productsAndSales[counter][0]; } return total0; }

  • Understanding Ruby class vs instance methods

    - by randombits
    I have the following code: #!/usr/bin/ruby class Person def self.speak p = self.new puts "Hello" p.chatter end private def chatter puts "Chattering" end end p = Person.new Person.speak I'd like to make chatter private, accessible only within p.. but I want p to be able to access it within the class method. Is there a better way to design this so chatter isn't available to the public, but a "factory" method like self.speak can call chatter?

  • Import XCode project inside another XCode project

    - by bruno
    I imported an XCode project inside another XCode project. I dragged and dropped project B inside project A like in How to Call Xcode Project In Another Xcode Project.......? Next, i imported a class from project B in project A, so i could use a method but i gave me an error "ClassTemp.h' file not found". From what i´ve read this should have worked. Do i have to do some kind of configuration for it to work?

How can i fix it?

  • Executing a .NET Managed Assembly from SQL Server 2008 - Pro's, Con's & Recommendations

    - by RPM1984
    Hi guys, looking for opinions/recommendations/links for the following scenario im currently facing. The Platform: .NET 4.0 Web Application SQL Server 2008 The Task: Overhaul a component of the system that performs (fairly) complex mathematical operations based on a specific user activity, and updates numerous tables in the database. A common user activity might be "Bob" decides to post a forum topic. This results in (the end-solution) needing to look at various factors (about the post he did), then after doing some math based on lookup values/ratios as well as other data in the database, inserting some other data as a result of these operations. The Options: Ok - so here's what im thinking. Although it would be much easier to do this in C# (LINQ-SQL) it doesnt make much sense as the majority of the computations are based on values in the db, and it will get difficult to control/optimize/debug the LINQ over time. Hence, im leaning towards created a managed assembly (C# Class Library) that contains the lookup values (constants) as well as leveraging the math classes in the existing .NET BCL. Basically i'd expose a few methods that can be called by the T-SQL Stored Procedures. This to me has the following advantages: Simplicity of math. Do complex math in .NET vs complex math in T-SQL. No brainer. =) Abstraction of computatations, configurable "lookup" values and business logic from raw T-SQL. T-SQL only needs to care about the data, simplifying the stored procedures and making it easier to maintain. When it needs to do math it delegates off to the managed assembly. So, having said that - ive never done this before (call .NET assmembly from T-SQL), and after some googling the best site i could come up with is here, which is useful but outdated. So - what am i asking? Well, firstly - i need some better references on how to actually do this. "This" being how to call a C# .NET 4 Assembly from within T-SQL Stored Procedures in SQL Server 2008. Secondly, who out there has done this, what problems (if any) did you face? Realize this may be difficult to provide a "correct answer", so ill try to give it to whoever gives me the answer with a combination of good links and a list of pro's/con's/problems with this implementation. Cheers!

  • How to maxmise the largest contiguous block of memory in the Large Object Heap

    - by Unsliced
    The situation is that I am making a WCF call to a remote server which is returns an XML document as a string. Most of the time this return value is a few K, sometimes a few dozen K, very occasionally a few hundred K, but very rarely it could be several megabytes (first problem is that there is no way for me to know). It's these rare occasions that are causing grief. I get a stack trace that starts: System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown. at System.Xml.BufferBuilder.AddBuffer() at System.Xml.BufferBuilder.AppendHelper(Char* pSource, Int32 count) at System.Xml.BufferBuilder.Append(Char[] value, Int32 start, Int32 count) at System.Xml.XmlTextReaderImpl.ParseText() at System.Xml.XmlTextReaderImpl.ParseElementContent() at System.Xml.XmlTextReaderImpl.Read() at System.Xml.XmlTextReader.Read() at System.Xml.XmlReader.ReadElementString() at Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationReaderMDRQuery.Read2_getMarketDataResponse() at Microsoft.Xml.Serialization.GeneratedAssembly.ArrayOfObjectSerializer2.Deserialize(XmlSerializationReader reader) at System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader, String encodingStyle, XmlDeserializationEvents events) at System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader, String encodingStyle) at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) I've read around and it is because the Large Object Heap is just getting too fragmented, so even preceding the call with a quick check to StringBuilder.EnsureCapacity just causes the OutOfMemoryException to be thrown earlier (and because I'm guessing at what's needed, it might not actually need that much so my check is causing more problems than it is solving). Some opinions are that there's not much I can do about it. Some of the questions I've asked myself: Use less memory - have you checked for leaks? Yes. The memory usage goes up and down, but there's no fundamental growth that guarantees this to happen. Some of the times it fails, it succeeded at that stage previously. Transfer smaller amounts Not an option, this is a third party web service over which I have no control (or at least it would take a long time to resolve, in the meantime I still have a problem) Can you do something to the LOH to make it less likely to fail? ... now this is most fruitful course. It's a 32-bit process (it has to be for various political, technical and boring reasons) but there's normally hundreds of meg free (multiples of the largest amount for which we've seen failures). Can we monitor the LOH? Using perfmon I can track the size of the heaps, but I don't think there's a way to monitor the largest available contiguous block of memory. Question is: any advice or suggestions for things to try?

  • How to handle unknown initializer functions in lua?

    - by oofoe
    I want to load data written in a variant of lua (eyeonScript). However, the data is peppered with references to initialization functions that are not in plain lua: Redden = BrightnessContrast { Inputs = { Red = Input { Value = 0, }, }, } Standard lua gives "attempt to call a nil value" or "unexpected symbol" errors. Is there any way to catch these and pass it to some sort of generic initializer? I want to wind up with a nested table data structure. Thanks!
