Reverse geocode street name and city as text

- by Taylor Satula

Hello, I have been having some trouble finding a good way to output just the street name and city as text (Infinite Loop, Cupertino shown here) that can be displayed in my iPhone app. This needs to be able to dynamically change as you change streets and city. I don't have the slightest idea of how to do this, I hope someone can help. I have attached a very rough image of what I am trying to acheave. I have found this (http://code.google.com/apis/maps/documentation/javascript/services.html#Geocoding) for google maps about how to reverse geocode using javascript, but what I do not understand is how this would be done in a iPhone development setting. I work in web design and I see how it would be done in HTML but I am very new to iPhone development and don't have the slightest clue of how it would be done here. If someone could spell out how to do this I would be extremely grateful. I cannot seem to find what I am looking for by searching Google.

Any useful suggestions to figure out where memory is being free'd in a Win32 process?

- by LeopardSkinPillBoxHat

An application I am working with is exhibiting the following behaviour: During a particular high-memory operation, the memory usage of the process under Task Manager (Mem Usage stat) reaches a peak of approximately 2.5GB (Note: A registry key has been set to allow this, as usually there is a maximum of 2GB for a process under 32-bit Windows) After the operation is complete, the process size slowly starts decreasing at a rate of 1MB per second. I am trying to figure out the easiest way to quickly determine who is freeing this memory, and where it is being free'd. I am having trouble attaching a memory profiler to my code, and I don't particularly want to override the new/delete operators to track the allocations/deallocations (IOW, I want to do this without re-compiling my code). Can anyone offer any useful suggestions of how I could do this via the Visual Studio debugger? Update I should also mention that it's a multi-threaded application, so pausing the application and analysing the call stack through the debugger is not the most desirable option. I considered freezing different threads one at a time to see if the memory stops reducing, but I'm fairly certain this will cause the application to crash.

Difference in clientX and clientY when going out of the browser on ie/ff

- by Py

I just ran into a little problem with clientX and clientY. I put a little event to detect if the mouse goes out of the window and to know where it exits. And there come the trouble, it works fine with firefox, but only sends -1 as an answer in IE. Does someone know if there is a way to solve easily that problem and that without using a framework? A little bit of code to reproduce that: <html> <head> <script type="text/javascript"> document.onmouseout=function(e){ if (!e) var e = window.event; var relTarg = e.relatedTarget || e.toElement; if (!relTarg){ document.getElementById('result1').innerHTML="e.clientY:"+e.clientY+" e.clientX:"+e.clientX; } }; </script> </head> <body> <div id="result1">Not Yet</div> </body> </html> the results if I exit through the left of the window are: e.clientY:302 e.clientX:-130 on firefox e.clientY:-1 e.clientX:-1 on ie. Thanks in advance.

Horizontal histogram won't accept input after the first input

- by vincentbelkin

So I'm making a program which is supposed to print a horizontal histogram of the lengths of words in its input. I don't know if most of it is OK since the main problem is it won't accept any input after the first one. Oh I also put comments on the parts I'm having some trouble with, like how to print "-" multiple times in order to represent histogram. I've tried making other versions of the code but I couldn't check if I'm close to getting it because again it won't accept another input after the first input. /*Write a program to print a histogram of the lengths of words in its input. It is easy to draw the histogram with the bars horizontal*/ #include <stdio.h> #define MAX 30 #define IN 1 #define OUT 0 int main() { int a,c,i,k,state,word[MAX]; a=0; k=0; state=OUT; for(i=0;i<MAX;i++) word[i]=0; while((c=getchar())!=EOF) { if(c==' '||c=='\t'||c=='\n') state=OUT; else state=IN; while(state==IN) a++; if(state==OUT) { word[i]=a; i++; } /*This part is hard for me, I don't know how to print X multiple times!*/ if((c==getchar())&&c==EOF) { for(i=0;i<MAX;i++) { for(i=0;i<=word[i];i++) putchar('-'); putchar('\n'); } } } }

Join Where Rows Don't Exist or Where Criteria Matches...?

- by Greg

I'm trying to write a query to tell me which orders have valid promocodes. Promocodes are only valid between certain dates and optionally certain packages. I'm having trouble even explaining how this works (see psudo-ish code below) but basically if there are packages associated with a promocode then the order has to have one of those packages and be within a valid date range otherwise it just has to be in a valid date range. The whole "if PrmoPackage rows exist" thing is really throwing me off and I feel like I should be able to do this without a whole bunch of Unions. (I'm not even sure if that would make it easier at this point...) Anybody have any ideas for the query? if `OrderPromoCode` = `PromoCode` then if `OrderTimestamp` is between `PromoStartTimestamp` and `PromoEndTimestamp` then if `PromoCode` has packages associated with it //yes then if `PackageID` is one of the specified packages //yes code is valid //no invalid //no code is valid Order: OrderID* | OrderTimestamp | PackageID | OrderPromoCode 1 | 1/2/11 | 1 | ABC 2 | 1/3/11 | 2 | ABC 3 | 3/2/11 | 2 | DEF 4 | 4/2/11 | 3 | GHI Promo: PromoCode* | PromoStartTimestamp* | PromoEndTimestamp* ABC | 1/1/11 | 2/1/11 ABC | 3/1/11 | 4/1/11 DEF | 1/1/11 | 1/11/13 GHI | 1/1/11 | 1/11/13 PromoPackage: PromoCode* | PromoStartTimestamp* | PromoEndTimestamp* | PackageID* ABC | 1/1/11 | 2/1/11 | 1 ABC | 1/1/11 | 2/1/11 | 3 GHI | 1/1/11 | 1/11/13 | 1 Desired Result: OrderID | IsPromoCodeValid 1 | 1 2 | 0 3 | 1 4 | 0

Applying the Decorator Pattern to Forms

- by devoured elysium

I am trying to apply the Decorator Design Pattern to the following situation: I have 3 different kind of forms: Green, Yellow, Red. Now, each of those forms can have different set of attributes. They can have a minimize box disabled, a maximized box disabled and they can be always on top. I tried to model this the following way: Form <---------------------------------------FormDecorator /\ /\ |---------|-----------| |----------------------|-----------------| GreenForm YellowForm RedForm MinimizeButtonDisabled MaximizedButtonDisabled AlwaysOnTop Here is my GreenForm code: public class GreenForm : Form { public GreenForm() { this.BackColor = Color.GreenYellow; } public override sealed Color BackColor { get { return base.BackColor; } set { base.BackColor = value; } } } FormDecorator: public abstract class FormDecorator : Form { private Form _decoratorForm; protected FormDecorator(Form decoratorForm) { this._decoratorForm = decoratorForm; } } and finally NoMaximizeDecorator: public class NoMaximizeDecorator : FormDecorator { public NoMaximizeDecorator(Form decoratorForm) : base(decoratorForm) { this.MaximizeBox = false; } } So here is the running code: static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(CreateForm()); } static Form CreateForm() { Form form = new GreenForm(); form = new NoMaximizeDecorator(form); form = new NoMinimizeDecorator(form); return form; } The problem is that I get a form that isn't green and that still allows me to maximize it. It is only taking in consideration the NoMinimizeDecorator form. I do comprehend why this happens but I'm having trouble understanding how to make this work with this Pattern. I know probably there are better ways of achieving what I want. I made this example as an attempt to apply the Decorator Pattern to something. Maybe this wasn't the best pattern I could have used(if one, at all) to this kind of scenario. Is there any other pattern more suitable than the Decorator to accomplish this? Am I doing something wrong when trying to implement the Decorator Pattern? Thanks

MSBUILD batch targets

- by Darthg8r

I want to deploy an application to a list of servers. I have all of the build issues taken care of, but I'm having trouble publishing to a list of servers. I want to read the list of servers from an external file and call a target passing the name of each server in. <ItemGroup> <File Include="$(SolutionFolder)CP\Build\DenormDevServers.txt" /> </ItemGroup> <Target Name="DeployToServer" Inputs="Servers" Outputs="Nothing"> <Message Text="Deployment to server done here. Deploying to server: @(Servers)" /> </Target> <Target Name="Test"> <ReadLinesFromFile File="@(File)"> <Output TaskParameter="Lines" ItemName="Servers" /> </ReadLinesFromFile> <CallTarget Targets="DeployToServer" ContinueOnError="true"></CallTarget> </Target> I can't seem to get it to "Deploy" to each server in the list. The output looks like this: Deployment to server done here. Deploying to server: Notice there is no server name, nor is done more than once. There are 2 lines in DenormDevServers.txt

JQuery - Check when image is loaded?

- by JasonS

Hi, I am having a bit of trouble working out when an image has been loaded. I have been told that the following function will work but it isn't doing anything. $("#photos img:first").load(function (){ alert("Image loaded!"); }); There are no error's in my code. Everything else in my script works great. My HTML looks like this. <div id="photos"> <img src="../sample1.jpg" style="background-color:#000033" width="1" height="1" alt="Frog!"/> <img src="../sample2.jpg" style="background-color:#999999" width="1" height="1" alt="Zooey!"/> </div> Do I have the wrong JQuery function? It should also be noted that the visibility is set to hidden. However even when visible there is no alert. Any ideas?

Still Confused About Identifying vs. Non-Identifying Relationships

- by Jason

So, I've been reading up on identifying vs. non-identifying relationships in my database design, and a number of the answers on SO seem contradicting to me. Here are the two questions I am looking at: What's the Difference Between Identifying and Non-Identifying Relationships Trouble Deciding on Identifying or Non-Identifying Relationship Looking at the top answers from each question, I appear to get two different ideas of what an identifying relationship is. The first question's response says that an identifying relationship "describes a situation in which the existence of a row in the child table depends on a row in the parent table." An example of this that is given is, "An author can write many books (1-to-n relationship), but a book cannot exist without an author." That makes sense to me. However, when I read the response to question two, I get confused as it says, "if a child identifies its parent, it is an identifying relationship." The answer then goes on to give examples such as SSN (is identifying of a Person), but an address is not (because many people can live at an address). To me, this sounds more like a case of the decision between primary key and non-primary key. My own gut feeling (and additional research on other sites) points to the first question and its response being correct. However, I wanted to verify before I continued forward as I don't want to learn something wrong as I am working to understand database design. Thanks in advance.

PHP OOP singleton doesn't return object

- by Misiur

Weird trouble. I've used singleton multiple times but this particular case just doesn't want to work. Dump says that instance is null. define('ROOT', "/"); define('INC', 'includes/'); define('CLS', 'classes/'); require_once(CLS.'Core/Core.class.php'); $core = Core::getInstance(); var_dump($core->instance); $core->settings(INC.'config.php'); $core->go(); Core class class Core { static $instance; public $db; public $created = false; private function __construct() { $this->created = true; } static function getInstance() { if(!self::$instance) { self::$instance = new Core(); } else { return self::$instance; } } public function settings($path = null) { ... } public function go() { ... } } Error code Fatal error: Call to a member function settings() on a non-object in path It's possibly some stupid typo, but I don't have any errors in my editor. Thanks for the fast responses as always.

Checking if a console application is still running using the Process class

- by Ced

I'm making an application that will monitor the state of another process and restart it when it stops responding, exits, or throws an error. However, I'm having trouble to make it reliably check if the process (Being a C++ Console window) has stopped responding. My code looks like this: public void monitorserver() { while (true) { server.StartInfo = new ProcessStartInfo(textbox_srcdsexe.Text, startstring); server.Start(); log("server started"); log("Monitor started."); while (server.Responding) { if (server.HasExited) { log("server exitted, Restarting."); break; } log("server is running: " + server.Responding.ToString()); Thread.Sleep(1000); } log("Server stopped responding, terminating.."); try { server.Kill(); } catch (Exception) { } } } The application I'm monitoring is Valve's Source Dedicated Server, running Garry's Mod, and I'm over stressing the physics engine to simulate it stopping responding. However, this never triggers the process class recognizing it as 'stopped responding'. I know there are ways to directly query the source server using their own protocol, but i'd like to keep it simple and universal (So that i can maybe use it for different applications in the future). Any help appreciated

Detecting const-ness of nested type

- by Channel72

Normally, if I need to detect whether a type is const I just use boost::is_const. However, I ran into trouble when trying to detect the const-ness of a nested type. Consider the following traits template, which is specialized for const types: template <class T> struct traits { typedef T& reference; }; template <class T> struct traits<const T> { typedef T const& reference; }; The problem is that boost::is_const doesn't seem to detect that traits<const T>::reference is a const type. For example: std::cout << std::boolalpha; std::cout << boost::is_const<traits<int>::reference>::value << " "; std::cout << boost::is_const<traits<const int>::reference>::value << std::endl; This outputs: false false Why doesn't it output false true?

EPL (Eclipse Public Licence) for commercial usage

- by code-gijoe

Hi, I'm developing an application which requires a third party framework which is under an Eclipse Public Licence (EPL). The application is a server-side commercial application which will be running on my servers. The EPL software is distributed as binaries (jar files). I'm only using the packages and am not making any contribution, i.e. not making any changes to the source. Under EPL I believe I'm not a "Contributor" nor am I making a "Contribution". But if I want to make my software available to be installed at some offsite server I'm having trouble with REQUIREMENTS of EPL: b.iv - "states that source code for the Program is available from such Contributor, and informs licensees how to obtain it in a reasonable manner on or through a medium customarily used for software exchange". Does this mean that if I where to modify the source code of the 3rd party framework for my own purposes I would need to distribute all of my source code? EPL is supposed to be commercially friendly but it doesn't seem that way to me. Thank you.

Android: FragmentAdapter and pageview do not update the view

- by user1240937

My trouble is: when i get new data, my viewpager that use my custom adapter do not update view. I discovered that many programmer got same bug, so i tried a lot of suggestion but no way works for me. So tired. One more time, read my source and help me understand why i fail with updating view pleaseee! Here is my FragmentAdapter: private class SwipeyTabsPagerAdapter extends FragmentPagerAdapter implements SwipeyTabsAdapter { private final Context mContext; private String[] datas; public SwipeyTabsPagerAdapter(Context context, FragmentManager fm, String[] ds) { super(fm); this.mContext = context; datas=ds; } @Override public int getItemPosition(Object object) { return POSITION_NONE; } @Override public Fragment getItem(int position) { Log.e("new item:", datas[position]); return SwipeyTabFragment.newInstance(datas[position]); } @Override public int getCount() { return datas.length; } public TextView getTab(final int position, SwipeyTabs root) { TextView view = (TextView) LayoutInflater.from(mContext).inflate( R.layout.swipey_tab_indicator, root, false); view.setText(datas[position]); view.setOnClickListener(new OnClickListener() { public void onClick(View v) { mViewPager.setCurrentItem(position); } }); return view; } } and here is where i set adapter: SwipeyTabsPagerAdapter adapter = new SwipeyTabsPagerAdapter(getApplicationContext(), getSupportFragmentManager(),dicts); mViewPager.setAdapter(adapter); mTabs.setAdapter(adapter); mViewPager.getAdapter().notifyDataSetChanged(); By logcat, can see clearly that: only first time, newItem be processed, so view can not be update.

Rails ActionCaching with Memcached fragment hit but action gets called anyway

- by baldtrol

Hi stackoverflow. I'm running into something strange. I'm using memcached with a caches_action setup. I'm doing this in 4 different controllers. In two of them, it works flawlessly (so far), though admittedly those two controllers are less complicated than the two in which it doesn't seem to work. I'm doing something like this: caches_action :index, :expires_in => 6.hours, :cache_path => Proc.new {|controller| controller.send(:generate_cache_path) }, :layout => false, :if => Proc.new { |c| c.request.format.js? } The intention behind the above is to cache some results that are dependent on the params. my :generate_cache_path method just takes into account some params and session vars and creates a unique key for memcached. I can see in memcached -vv that this is working. What's weird is that I get my request from the rails app for a given key, and I see memcached (with -vv) get the request and send back the response. But then my action runs anyway, and a new value is then set for the same key, even when all the same params are given. I can watch it happen. In the controllers where everything is working, the request is made for the fragment, it gets it, and the action in the controller is halted, and the fragment is passed back. These lines come from the exact same request: Cached fragment hit: views/items/?page=1&rp=10&srtn=created_at&srto=DESC.js And then: Cached fragment miss: views/items/?page=1&rp=10&srtn=created_at&srto=DESC.js I don't know what to make of it, or if I'm doing something stupid. Any help or ideas where I could start looking for trouble would be greatly appreciated.

EF4 Code First - Many to many relationship issue

- by Yngve B. Nilsen

Hi! I'm having some trouble with my EF Code First model when saving a relation to a many to many relationship. My Models: public class Event { public int Id { get; set; } public string Name { get; set; } public virtual ICollection<Tag> Tags { get; set; } } public class Tag { public int Id { get; set; } public string Name { get; set; } public virtual ICollection<Event> Events { get; set; } } In my controller, I map one or many TagViewModels into type of Tag, and send it down to my servicelayer for persistence. At this time by inspecting the entities the Tag has both Id and Name (The Id is a hidden field, and the name is a textbox in my view) The problem occurs when I now try to add the Tag to the Event. Let's take the following scenario: The Event is already in my database, and let's say it already has the related tags C#, ASP.NET If I now send the following list of tags to the servicelayer: ID Name 1 C# 2 ASP.NET 3 EF4 and add them by first fetching the Event from the DB, so that I have an actual Event from my DbContext, then I simply do myEvent.Tags.Add to add the tags.. Problem is that after SaveChanges() my DB now contains this set of tags: ID Name 1 C# 2 ASP.NET 3 EF4 4 C# 5 ASP.NET This, even though my Tags that I save has it's ID set when I save it (although I didn't fetch it from the DB)

JSP:Include not rendering the page correctly

- by sreekanth

am having trouble with including a jsp page with tag. This is what is happening. I making changes to a portlet application running on Websphere 7 server. This is the hierarchy of the jsp pages. blankPage.jsp --bookingViewTabs.jsp -- availableRooms.jsp meaning blankPage is included in bookingViewTabs which is inturn included in availableRooms.jsp I have 2 problems with this. (1). The blankPage.jsp does not render correctly on the screen. It gets cutoff (2). The other is in blankPage.jsp there is a form called "guestProfileSearchResultsFormId". this form has several hidden fields for data. example, "guestId" which is a child of that form and can be accessed formname.fieldname, but when i include that page into another jsp as the first include(there are several includes on the page) under the another form tag, the form field is not being rendered as a child of the form, but as a sibling of the form. If i change the order and include some other page and include this, it is working as it is supposed to have. meaning with children intact. I don't understand this behavior. I HAVE ATTACHED A GIF IMAGE OF WHAT I SEE ON THE BROWSER Any help is greatly appreciated. Thanks in advance

how to merge ecommerce transaction data between two databases

- by yamspog

We currently run an ecommerce solution for a leisure and travel company. Everytime we have a release, we must bring the ecommerce site down as we update database schema and the data access code. We are using a custom built ORM where each data entity is responsible for their own CRUD operations. This is accomplished by dynamically generating the SQL based on attributes in the data entity. For example, the data entity for an address would be... [tableName="address"] public class address : dataEntity { [column="address1"] public string address1; [column="city"] public string city; } So, if we add a new column to the database, we must update the schema of the database and also update the data entity. As you can expect, the business people are not too happy about this outage as it puts a crimp in their cash-flow. The operations people are not happy as they have to deal with a high-pressure time when database and applications are upgraded. The programmers are upset as they are constantly getting in trouble for the legacy system that they inherited. Do any of you smart people out there have some suggestions?

Static Variables somehow maintaining state?

- by gfoley

I am working on an existing project, setup by another coder. I'm having some trouble understanding how state is being maintained between pages. There is a Class library which has some helper objects. Mostly these objects are just used for there static methods and rarely instantiated or inherited. This is an example class I'm testing with. public sealed class Application { public static string Test; } Now when i run something like the following in the base class of my page, I would expect the result to be "1: 2:Test" all the time (note that "1" is empty), but strangly its only this way the first time it is run. Then every time afterwards its "1:Test 2:Test". Somehow its maintaining the state of the static variable between pages and being refreshed?? Response.Write("1:" + SharedLibrary.Application.Test); SharedLibrary.Application.Test = "Test"; Response.Write(" 2:" + SharedLibrary.Application.Test); I need to create more classes like this, but want to understand why this is occurring in the first place. Many Thanks

Does Hibernate support one-to-one associations as pkeys?

- by Andrzej Doyle

Hi all, Can anyone tell me whether Hibernate supports associations as the pkey of an entity? I thought that this would be supported but I am having a lot of trouble getting any kind of mapping that represents this to work. In particular, with the straight mapping below: @Entity public class EntityBar { @Id @OneToOne(optional = false, mappedBy = "bar") EntityFoo foo // other stuff } I get an org.hibernate.MappingException: "Could not determine type for: EntityFoo, at table: ENTITY_BAR, for columns: [org.hibernate.mapping.Column(foo)]" Diving into the code it seems the ID is always considered a Value type; i.e. "anything that is persisted by value, instead of by reference. It is essentially a Hibernate Type, together with zero or more columns." I could make my EntityFoo a value type by declaring it serializable, but I wouldn't expect this would lead to the right outcome either. I would have thought that Hibernate would consider the type of the column to be integer (or whatever the actual type of the parent's ID is), just like it would with a normal one-to-one link, but this doesn't appear to kick in when I also declare it an ID. Am I going beyond what is possible by trying to combine @OneToOne with @Id? And if so, how could one model this relationship sensibly?

In Powerpoint 2007, how can I position a Callout's Tail programatically?

- by Rorschach

I'm looking at the XML and this is what it has for the Callout object's coordinates and geometry: <p:spPr> <a:xfrm> <a:off x="2819400" y="5181600"/> // X,Y Position of Callout Box <a:ext cx="609600" cy="457200"/> // Width,Height of Callout Box </a:xfrm> <a:prstGeom prst="wedgeRectCallout"> <a:avLst> <a:gd name="adj1" fmla="val 257853"/> // X Position Of Tail <a:gd name="adj2" fmla="val -532360"/> // Y Position of Tail </a:avLst> </a:prstGeom> <a:solidFill> <a:schemeClr val="accent1"> <a:alpha val="50000"/> </a:schemeClr> </a:solidFill> </p:spPr> What I'm having trouble with is the formula for telling it to place the tail at a particular coordinate on the slide. I've tried this to calculate it, but it does not work correctly. //This gives me the distance between the Coordinate and the Center of the Callout. DistanceX = Coordinate.X - (Callout.X + Callout.X_Ext)/2 DistanceY = Coordinate.Y - (Callout.Y + Callout.Y_Ext)/2 But, the geometric value is not the distance between the two points. Anybody know what the formula is for calculating this?

Passing javascript object to webservice via Jquery ajax

- by kralco626

I have a webservice that returns an object [WebMethod] public List<User> ContractorApprovals() I also have a webservice that accepcts an object [WebMethod] public bool SaveContractor(Object u) When I make my webservice calls via Jquery: function ServiceCall(method, parameters, onSucess, onFailure) { var parms = "{" + (($.isArray(parameters)) ? parameters.join(',') : parameters) + "}"; // to json $.ajax({ type: "POST", url: "services/"+method, data: parms, contentType: "application/json; charset=utf-8", dataType: "json", success: function(msg) { if (typeof onSucess == 'function' || typeof onSucess == 'object') onSucess(msg.d); }, error: function(msg, err) { $("#dialog-error").dialog('open');} }); I can call the first one just fine. My onSucess function gets passed a javascript object exactly structured like my User object on the service. However, I am now having trouble getting the object back to the server. I'm accepting Object as a parameter on the server side so I can't inagine there is an issue there. So I'm thinking something is wrong with the parms on the client side but i'm not sure what... I am doing something to the effect ServiceCall("AuthorizationManagerWorkManagement.asmx/ContractorApprovals", "", function(data,args){$("#div").data('user',data[0])}, null) then ServiceCall("AuthorizationManagerWorkManagement.asmx/SaveContractor", $("#div").data('user'), //These also do not work: "{'u': ' + $("#div").data("user") + '}", NOR JSON.stringify({u: userObject}) function(data,args){(alert(data)}, null) I know the first service call works, I can get the data. The second one is causing the "onFailure" method to execute rather then "OnSuccess". Any ideas?

Schema for element with Attributes and Child nodes

- by Matthew

I am trying to write xsd type schema for an element that has a custom type to include addition attributes to extend a base type. I am running into trouble getting the syntax right. <xs:element name="graphs"> <xs:complexType> <xs:sequence> <xs:element name="graph" minOccurs="1" maxOccurs="unbounded" type="graphType">  </xs:element> </xs:sequence> </xs:complexType> </xs:element> <xs:complexType name="graphType"> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute name="title" type="xs:string"/> <xs:attribute name="type" type="xs:string"/> </xs:extension> </xs:simpleContent> </xs:complexType> I thought this would be something very common, but having read many tuts and forums, I cant seem to find an answer that works for me.
