  • jQuery toggle caching / cookies

    - by user1706680
    I’m using the jQuery toggle function for my navigation. By default the Authors toggle is visible, the Archives toggle is closed. http://jsfiddle.net/TeDFs/4/ My problem is that when the users switches to another page the toggles reset themselves. For example, when the user closes the Authors toggle and opens the Archive toggle and then navigates to another page the default settings are loaded. I read that it’s possible to store the settings via cookies but I’m absolutely new to jQuery and it would be great if somebody could help me out! HTML <div id="authors" class="widget"> <h2 class="widget-title-visible">Authors</h2> <div class="toggle"> <div class="submenu"> <ul> <li>Name 1</li> <li>Name 2</li> <li>Name 3</li> <li>Name 3</li> </ul> </div> </div> <div id="archives" class="widget"> <h2 class="widget-title">Archiv</h2> <div class="toggle hidden"> <div class="submenu"> <ul> <li>November 2012</li> <li>Oktober 2012</li> </ul> </div> </div> </div>? jQuery function toggleWidgets() { jQuery('.widget-title').addClass('plus'); jQuery('.widget-title-visible').addClass('minus'); jQuery('.widget-title').click(function() { $(this).toggleClass('plus').toggleClass('minus').next().toggle(180); }); jQuery('.widget-title-visible').click(function() { $(this).toggleClass('minus').toggleClass('plus').next().toggle(180); }); } jQuery(document).ready(function() { toggleWidgets(); } )? CSS .hidden{ display:none; } .plus { background: url(http://moargh.de/daten/sidebar_arrows.png) 0 5px no-repeat; padding: 0 0 0 12px; } .minus { background: url(http://moargh.de/daten/sidebar_arrows.png) 0 -10px no-repeat; padding: 0 0 0 12px; }

  • What are the differences between these?

    - by Amit Ranjan
    What are the differences between the two queries? SELECT CountryMaster.Id FROM Districts INNER JOIN CountryMaster ON Districts.CountryId = CountryMaster.Id SELECT CountryMaster.Id FROM CountryMaster INNER JOIN Districts ON Districts.CountryId = CountryMaster.Id Please mind the i) Table positions and second ii) On Fields As I know, output will be same. But I want to know, is there any drastic effects of the same if I neglect positions of tables and columns in complex queries or tables having tons of data like thousands and lakhs of rows...

  • Robust way to save/load objects with dependencies?

    - by mrteacup
    I'm writing an Android game in Java and I need a robust way to save and load application state quickly. The question seems to apply to most OO languages. To understand what I need to save: I'm using a Strategy pattern to control my game entities. The idea is I have a very general Entity class which e.g. stores the location of a bullet/player/enemy and I then attach a Behaviour class that tells the entity how to act: class Entiy { float x; float y; Behavior b; } abstract class Behavior { void update(Entity e); {} // Move about at a constant speed class MoveBehavior extends Behavior { float speed; void update ... } // Chase after another entity class ChaseBehavior extends Behavior { Entity target; void update ... } // Perform two behaviours in sequence class CombineBehavior extends Behavior { Behaviour a, b; void update ... } Essentially, Entity objects are easy to save but Behaviour objects can have a semi-complex graph of dependencies between other Entity objects and other Behaviour objects. I also have cases where a Behaviour object is shared between entities. I'm willing to change my design to make saving/loading state easier, but the above design works really well for structuring the game. Anyway, the options I've considered are: Use Java serialization. This is meant to be really slow in Android (I'll profile it sometime). I'm worried about robustness when changes are made between versions however. Use something like JSON or XML. I'm not sure how I would cope with storing the dependencies between objects however. Would I have to give each object a unique ID and then use these IDs on loading to link the right objects together? I thought I could e.g. change the ChaseBehaviour to store a ID to an entity, instead of a reference, that would be used to look up the Entity before performing the behaviour. I'd rather avoid having to write lots of loading/saving code myself as I find it really easy to make mistakes (e.g. forgetting to save something, reading things out in the wrong order). Can anyone give me any tips on good formats to save to or class designs that make saving state easier?

  • NHibernate Many-to-Many Mapping not working

    - by ClutchDude
    I have a Nhibernate mapping file for a simple user/role mapping. Here are the mapping files: Users.hbm.xml <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="Sample.Persistence" namespace="Sample.Persistence.Model"> <class name="User" table="Users"> <id name="UserKey"> <generator class="identity"/> </id> <property name="UserName" column="UserName" type="String" /> <property name="Password" column="Password" type="Byte[]" /> <property name="FirstName" column="FirstName" type="String" /> <property name="LastName" column="LastName" type="String" /> <property name="Email" column="Email" type="String" /> <property name="Active" column="Active" type="Boolean" /> <property name="Locked" column="Locked" type="Boolean" /> <property name="LoginFailures" column="LoginFailures" type="int" /> <property name="LockoutDate" column="LockoutDate" type="DateTime" generated="insert" /> <property name="Expired" column="Expired" type="Boolean" generated="insert"/> <set name="Roles" table="UsersRolesBridge" lazy="false"> <key column="UserKey" /> <many-to-many class="Role" not-found="exception" column="RoleKey" /> </set> </class> </hibernate-mapping> Role.hbm.xml <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="Sample.Persistence" namespace="Sample.Persistence.Model"> <class name="Role" table="Roles"> <id name="RoleKey"> <generator class="identity"/> </id> <property name="Name" column="Name" type="String" /> <set name="Users" inverse="true" atable="UsersRolesBridge" lazy="false" > <key column="RoleKey" /> <many-to-many class="User" column="UserKey" /> </set> </class> </hibernate-mapping> I am able to retrieve roles for each user via NHibernate but when I go to save a new object, the roles are not saved in the Bridge table. The user is created and insert with no issues. I've checked that the Role collection, a field on the user, is being populated with the proper rolekey before the Session.Save() is called. There is no exception thrown as well.

  • What are nested/unnested package in Scala 2.8?

    - by retronym
    In Scala 2.7, I could write: package com.acme.bar class Bar . package com.acme.foo class Foo { new bar.Bar } This doesn't compile in Scala 2.8 -- however this does: package com.acme package bar class Bar . package com.acme package foo class Foo { new bar.Bar } What was the motivation for this? What is the precise meaning, with regards to scope and visibility? When should I use one form over the other?

    I have two classes X and Y, like this: class X implements Serializable { int val1; Y val2; } class Y implements Serializable { int val; } I want to transmit an object of type X from a client to server but i can't because the class X has a field of type Y. I replace the field of type Y with a field of type X in class X and it works.

  • Select latest group by in nhibernate

    - by Kendrick
    I have Canine and CanineHandler objects in my application. The CanineHandler object has a PersonID (which references a completely different database), an EffectiveDate (which specifies when a handler started with the canine), and a FK reference to the Canine (CanineID). Given a specific PersonID, I want to find all canines they're currently responsible for. The (simplified) query I'd use in SQL would be: Select Canine.* from Canine inner join CanineHandler on(CanineHandler.CanineID=Canine.CanineID) inner join (select CanineID,Max(EffectiveDate) MaxEffectiveDate from caninehandler group by CanineID) as CurrentHandler on(CurrentHandler.CanineID=CanineHandler.CanineID and CurrentHandler.MaxEffectiveDate=CanineHandler.EffectiveDate) where CanineHandler.HandlerPersonID=@PersonID Edit: Added mapping files below: <class name="CanineHandler" table="CanineHandler" schema="dbo"> <id name="CanineHandlerID" type="Int32"> <generator class="identity" /> </id> <property name="EffectiveDate" type="DateTime" precision="16" not-null="true" /> <property name="HandlerPersonID" type="Int64" precision="19" not-null="true" /> <many-to-one name="Canine" class="Canine" column="CanineID" not-null="true" access="field.camelcase-underscore" /> </class> <class name="Canine" table="Canine"> <id name="CanineID" type="Int32"> <generator class="identity" /> </id> <property name="Name" type="String" length="64" not-null="true" /> ... <set name="CanineHandlers" table="CanineHandler" inverse="true" order-by="EffectiveDate desc" cascade="save-update" access="field.camelcase-underscore"> <key column="CanineID" /> <one-to-many class="CanineHandler" /> </set> <property name="IsDeleted" type="Boolean" not-null="true" /> </class> I haven't tried yet, but I'm guessing I could do this in HQL. I haven't had to write anything in HQL yet, so I'll have to tackle that eventually anyway, but my question is whether/how I can do this sub-query with the criterion/subqueries objects. I got as far as creating the following detached criteria: DetachedCriteria effectiveHandlers = DetachedCriteria.For<Canine>() .SetProjection(Projections.ProjectionList() .Add(Projections.Max("EffectiveDate"),"MaxEffectiveDate") .Add(Projections.GroupProperty("CanineID"),"handledCanineID") ); but I can't figure out how to do the inner join. If I do this: Session.CreateCriteria<Canine>() .CreateCriteria("CanineHandler", "handler", NHibernate.SqlCommand.JoinType.InnerJoin) .List<Canine>(); I get an error "could not resolve property: CanineHandler of: OPS.CanineApp.Model.Canine". Obviously I'm missing something(s) but from the documentation I got the impression that should return a list of Canines that have handlers (possibly with duplicates). Until I can make this work, adding the subquery isn't going to work... I've found similar questions, such as http://stackoverflow.com/questions/747382/only-get-latest-results-using-nhibernate but none of the answers really seem to apply with the kind of direct result I'm looking for. Any help or suggestion is greatly appreciated.

  • How can I get access to spring container?

    - by Antony
    I have a spring container running, and I have class with which I want to have access to the bean created inside spring container. The class I have is not registered with the spring container. One thing I can do is that I can use MethodInvoker to call a static method, so I will have access to static field (this would be a bean from spring container) in my class always. Do we have class like WebapplicationContextUtils for a application that is not web?

  • python object to native c++ pointer

    - by Lodle
    Im toying around with the idea to use python as an embedded scripting language for a project im working on and have got most things working. However i cant seem to be able to convert a python extended object back into a native c++ pointer. So this is my class: class CGEGameModeBase { public: virtual void FunctionCall()=0; virtual const char* StringReturn()=0; }; class CGEPYGameMode : public CGEGameModeBase, public boost::python::wrapper<CGEPYGameMode> { public: virtual void FunctionCall() { if (override f = this->get_override("FunctionCall")) f(); } virtual const char* StringReturn() { if (override f = this->get_override("StringReturn")) return f(); return "FAILED TO CALL"; } }; Boost wrapping: BOOST_PYTHON_MODULE(GEGameMode) { class_<CGEGameModeBase, boost::noncopyable>("CGEGameModeBase", no_init); class_<CGEPYGameMode, bases<CGEGameModeBase> >("CGEPYGameMode", no_init) .def("FunctionCall", &CGEPYGameMode::FunctionCall) .def("StringReturn", &CGEPYGameMode::StringReturn); } and the python code: import GEGameMode def Ident(): return "Alpha" def NewGamePlay(): return "NewAlpha" def NewAlpha(): import GEGameMode import GEUtil class Alpha(GEGameMode.CGEPYGameMode): def __init__(self): print "Made new Alpha!" def FunctionCall(self): GEUtil.Msg("This is function test Alpha!") def StringReturn(self): return "This is return test Alpha!" return Alpha() Now i can call the first to functions fine by doing this: const char* ident = extract< const char* >( GetLocalDict()["Ident"]() ); const char* newgameplay = extract< const char* >( GetLocalDict()["NewGamePlay"]() ); printf("Loading Script: %s\n", ident); CGEPYGameMode* m_pGameMode = extract< CGEPYGameMode* >( GetLocalDict()[newgameplay]() ); However when i try and convert the Alpha class back to its base class (last line above) i get an boost error: TypeError: No registered converter was able to extract a C++ pointer to type class CGEPYGameMode from this Python object of type Alpha I have done alot of searching on the net but cant work out how to convert the Alpha object into its base class pointer. I could leave it as an object but rather have it as a pointer so some non python aware code can use it. Any ideas?

  • Muliple Models in a single django ModelForm?

    - by BigJason
    Is it possible to have multiple models included in a single ModelForm in django? I am trying to create a profile edit form. So I need to include some fields from the User model and the UserProfile model. Currently I am using 2 forms like this class UserEditForm(ModelForm): class Meta: model = User fields = ("first_name", "last_name") class UserProfileForm(ModelForm): class Meta: model = UserProfile fields = ("middle_name", "home_phone", "work_phone", "cell_phone") Is there a way to consolidate these into one form or do I just need to create a form and handle the db loading and saving myself?

  • How should I organize my C# classes? [closed]

    - by oscar.fimbres
    I'm creating an email generator system. I'm creating some clases and I'm trying to make things right. By the time, I have created 5 classes. Look at the class diagram: I'm going to explain you each one. Person. It's not a big deal. Just have two constructors: Person(fname, lname1, lname2) and Person(token, fname, lname1, lname2). Note that email property stays without value. StringGenerator. This is a static class and it has only a public function: Generate. The function receives a Person class and it will return a list of patterns for the email. MySql. It contains all the necessary to connect to a database. Database. This class inherits from MySql class. It has particular functions for the database. This gets all the registries from a table (function GetPeople) and return a List. Each person from the list contains all data except Email. Also it can add records (List but this must contains an available email). An available email is when an email doesn't have another person. For that reason, I have a method named ExistsEmail. Container. This is the class which is causing me some problems. It's like a temporary container. It supposed to have a people list from GetPeople (in Database class) and for each person it adds, it must generate a list of possible names (StringGenerator.Generate), then it selects one of the list and it must check out if exists in the database or in the same container. As I told above this is temporal, it may none of the possible emails is available. So the user can modify or enter a custom email available and update the list in this container. When all the email's people are available, it sends a list to add in the database, It must have a Flush method, to insert all the people in the database. I'm trying to design correct class. I need a little help to improve or edite the classes, because I want to separate the logic and visual, and learn of you. I hope you've been able to understand me. Any question or doubt, please let me know. Anyway, I attached the solution here to better understand it: http://www.megaupload.com/?d=D94FH8GZ

  • How to add fadeIn and fadeOut to idTabs plugin's JS snippet?

    - by iMagdy
    Hi, I am using the jQuery plugin idTabs [ [www.sunsean.com/idTabs][1] ] and it allows me to line tabs and tabs' content via element#id and element href="#id" Ok, so I use this snippet: <script type="text/javascript"> $(document).ready(function() { $("#requestPool").idTabs(); $(".tabs").idTabs(); $(".miniTabs").idTabs(".active"); $(".switchers").idTabs(".activePanel"); }); </script> To run the plugin on two different areas: div#requestPool this has it's own tabs and it's own tab content, Also the div.tabs which is another place and has it's own tabs and it's own tabs content. The div.miniTabs and div.switchers are the divs that includes the tabs links (tabs headers) and I putted them in the snippet to change the default selected tab class from .selected to .active and .activePanel Now, what I would love to add is a nice fadeIn and fadeOut effects to the content of my tabs while browsing through them. Thanks Here is the HTML code for one of the tabbed areas: <div id="requestPool"> <!-- The tabs heads --> <div class="miniTabs"> <a href="#today" class="active">Today</a> <!-- First active tab --> <a href="#tomorrow">Tomorrow</a> <a href="#friday">Friday</a> <a href="#saturday">Saturday</a> <a href="#sunday">Sunday</a> <a href="#monday">Monday</a> <a href="#tuesday">Tuesday</a> </div> <!-- The tabs contents (the ones that I want them to fade in and out while browsing through them using the tabs above) --> <div id="today"class="miniTab"></div> <div id="tomorrow"class="miniTab"></div> <div id="friday"class="miniTab"></div> <div id="saturday"class="miniTab"></div> <div id="sunday"class="miniTab"></div> ...etc the week days </div> Thanks very much (again the tabs are working very fine, but without the fade effect which I want to have).

  • C++Template in Java?

    - by RnMss
    I want something like this: public abstract class ListenerEx<LISTENER, PARENT> implements LISTENER { PARENT parent; public ListenerEx(PARENT p) { parent = p; } } But it doesn't compile. Is there a better solution? Is there something in Java like C++ template that would do check syntax after template deduction? The following explains why I need such a ListenerEX class, if you already know what it is, you don't need to read the following. I have a main window, and a button on it, and I want to get access to some method of the main window's within the listener: public class MainWindow extends JFrame { public void doSomething() { /* ... */ } public void doSomethingElse() { /* ... */ } private JButton button; public MainWindow() { button = new JButton(...); add(button); button.setActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { doSomething(); doSomethingElse(); } }); } } This would compile but does not work properly all the time. (Why would it compile when the ActionListener does not have doSomething() method?) Of course we can do it like this: public class MainWindow extends JFrame { public void doSomething() { } public void doSomethingElse() { } private JButton button; public MainWindow() { button = new JButton(...); add(button); class ActionListener1 implements ActionListener { MainWindow parent; public ActionListener(MainWindow p) { parent = p; } public void actionPerformed(ActionEvent e) { parent.doSomething(); parent.doSomethingElse(); } } button.setActionListener(new ActionListener1(this)); } } However I hate this style ... So I tried: public abstract class ActionListenerEx<P> implements ActionListener { P parent; public ActionListenerEx(P p) { parent = p; } } public class MainWindow extends JFrame { public void doSomething() { } public void doSomethingElse() { } private JButton button; public MainWindow() { button = new JButton(...); add(button); button.setActionListener(new ActionListenerEx<MainWindow>(this) { public void actionPerformed(ActionEvent e) { parent.doSomething(); parent.doSomethingElse(); } }); } } But there's lots of Listeners beside the ActionListener ... public abstract class ActionListenerEx<LISTENER, PARENT> implements LISTENER { PARENT parent; public ActionListenerEx(PARENT p) { parent = p; } } However, it won't compile ... I am fresh at Java, and I wonder if there's already better solution.

  • C# some sort of plugin system

    - by nLL
    Hi, I am a mobile web developer and trying to monetize my traffic with mobile ad services and i have a problem. First of all to get most of out of your ads you usually need to do server side request to advert company's servers and there are quite few ad services. Problem starts when you want to use them in one site. All have different approaches to server side calls and trying to maintain and implement those ad codes becomes pain after a while. So I decided to write a class system where i can simply create methods for every company and upload it to my site. So far i have public Advert class public AdPublisher class with GetAd method that returns an Advert public Adservice class that has Service names as enum I also have converted server request codes of all ad services i use to classes. It works ok but I want to be able to create an ad service class upload it so that asp.net app can import/recognize it automatically like a plugin system. As I am new to .net I have no idea where to start or how to do it. To make thing clear here are my classes namespace Mobile.Publisher { public class AdPublisher { public AdPublisher() { IsTest = false; } public bool IsTest { get; set; } public HttpRequest CurrentVisitorRequestInfo { get; set; } public Advert GetAd(AdService service) { Advert returnAd = new Advert(); returnAd.Success = true; if (this.CurrentVisitorRequestInfo == null) { throw new Exception("CurrentVisitorRequestInfo for AdPublisher not set!"); } if (service == null) { throw new Exception("AdService not set!"); } if (service.ServiceName == AdServices.Admob) { returnAd.ReturnedAd = AdmobAds("000000"); } return returnAd; } } public enum AdServices { Admob, ServiceB, ServiceC } public class Advert { public bool Success { get; set; } public string ReturnedAd { get; set; } } public partial class AdService { public AdServices ServiceName { get; set; } public string PublisherOrSiteId { get; set; } public string ZoneOrChannelId { get; set; } } private string AdmobAds(string publisherid) { //snip return "test" } } Basically i want to be able to add another ad service and code like private string AdmobAds(string publisherid){ } So that it can be imported and recognised as ad service. I hope i was clear enough

  • Subclassing and adding data members

    - by Marius
    I have an hierarchy of classes that looks like the following: class Critical { public: Critical(int a, int b) : m_a(a), m_b(b) { } virtual ~Critical() { } int GetA() { return m_a; } int GetB() { return m_b; } void SetA(int a) { m_a = a; } void SetB(int b) { m_b = b; } protected: int m_a; int m_b; }; class CriticalFlavor : public Critical { public: CriticalFlavor(int a, int b, int flavor) : Critical(a, b), m_flavor(flavor) { } virtual ~CriticalFlavor() { } int GetFlavor() { return m_flavor; } void SetFlavor(int flavor) { m_flavor = flavor; } protected: int m_flavor; }; class CriticalTwist : public Critical { public: CriticalTwist(int a, int b, int twist) : Critical(a, b), m_twist(twist) { } virtual ~CriticalTwist() { } int GetTwist() { return m_twist; } void SetTwist(int twist) { m_twist = twist; } protected: int m_twist; }; The above does not seem right to me in terms of the design and what bothers me the most is the fact that the addition of member variables seems to drive the interface of these classes (the real code that does the above is a little more complex but still embracing the same pattern). That will proliferate when in need for another "Critical" class that just adds some other property. Does this feel right to you? How could I refactor such code? An idea would be to have just a set of interfaces and use composition when it comes to the base object like the following: class Critical { public: virtual int GetA() = 0; virtual int GetB() = 0; virtual void SetA(int a) = 0; virtual void SetB(int b) = 0; }; class CriticalImpl { public: CriticalImpl(int a, int b) : m_a(a), m_b(b) { } ~CriticalImpl() { } int GetA() { return m_a; } int GetB() { return m_b; } void SetA(int a) { m_a = a; } void SetB(int b) { m_b = b; } private: int m_a; int m_b; }; class CriticalFlavor { public: virtual int GetFlavor() = 0; virtual void SetFlavor(int flavor) = 0; }; class CriticalFlavorImpl : public Critical, public CriticalFlavor { public: CriticalFlavorImpl(int a, int b, int flavor) : m_flavor(flavor), m_critical(new CriticalImpl(a, b)) { } ~CriticalFlavorImpl() { delete m_critical; } int GetFlavor() { return m_flavor; } void SetFlavor(int flavor) { m_flavor = flavor; } int GetA() { return m_critical-GetA(); } int GetB() { return m_critical-GetB(); } void SetA(int a) { m_critical-SetA(a); } void SetB(int b) { m_critical-SetB(b); } private: int m_flavor; CriticalImpl* m_critical; };

  • Problem with Command Pattern under Visual Studio 2008 (C++)

    Dear All, I've a problem with this pattern under c++ on VS 2008. The same code has been tested in gcc (linux, mac and mingw for widnows) and it works. I copy/paste the code here: class MyCommand { public: virtual void execute() = 0; virtual ~MyCommand () {}; }; class MyOperation { public: virtual void DoIt() {}; //I also write it not inline }; class MyOperationDerived : public MyOperation { public: virtual void DoIt() {}; //I also write it not inline }; class MyUndoStackCommand : public MyCommand { public: typedef void(MyOperation::*Action)(); MyUndoStackCommand(MyOperation *rec, Action action); /*virtual*/ void execute(); /*virtual*/ ~MyUndoStackCommand(); private: MyOperation *myReceiver; Action myAction ; }; in cpp: #include "MyUndoStackCommand.h" #include "MyOperation.h" MyUndoStackCommand::~MyUndoStackCommand() { } MyUndoStackCommand::MyUndoStackCommand(myOperation *rec, Action action): myReceiver(rec), myAction(action) { } void MyUndoStackCommand::execute() { ((myReceiver)->*(myAction))(); } use in main.cpp: MyReceiver receiver; MyUndoStackCommand usc(&receiver, &MyOperation::DoIt); usc.execute(); when I debug under visual studio only if I set inside MyUndoStackCommand, directly myAction = &MyOperation::DoIt , it works, otherwise not. Any advice? thank you very much, dan Edit: The following code compiles with g++ - changes by Neil Butterworth flagged as //NB. class MyCommand { public: virtual void execute() = 0; virtual ~MyCommand () {}; }; class MyOperation { public: virtual void DoIt() {}; //I also write it not inline }; class MyOperationDerived : public MyOperation { public: virtual void DoIt() {}; //I also write it not inline }; class MyUndoStackCommand : public MyCommand { public: typedef void(MyOperation::*Action)(); MyUndoStackCommand(MyOperation *rec, Action action); /*virtual*/ void execute(); /*virtual*/ ~MyUndoStackCommand(); private: MyOperation *myReceiver; Action myAction ; }; MyUndoStackCommand::~MyUndoStackCommand() { } MyUndoStackCommand::MyUndoStackCommand(MyOperation *rec, //NB Action action) : myReceiver(rec), myAction(action) { } void MyUndoStackCommand::execute() { ((myReceiver)->*(myAction))(); } int main() { MyOperation receiver; //NB MyUndoStackCommand usc(&receiver, &MyOperation::DoIt); usc.execute(); }

  • Percentage function for a group based on another group.

    - by Jeff O
    I have two grouping levels in a report. Group A can have a Percentage() of the entire report and so can Group B, but I would like to know the Percentage() of Group A of Group B. Even if I code it, it seems like once the inner and outer groups have created their footers, I can't go back to to the inner group and set it's value. Example: Group A Total 50 Group A percentage of Report Total = 33% Group A Percentage of Group B Total = 33% but I want 50% Group B Total 100 Group B Percentage of Report Total = 66% Report Total 150
