• Mapping self-table one-to-many using non-PK clolumns

  - by Harel Moshe

  Hey, i have a legacy DB to which a Person object is mapped, having a collection of family-members, like this: class Person { ... string Id; /* 9-digits string */ IList<Person> Family; ... } The PERSON table seems like: Id: CHAR(9), PK FamilyId: INT, NOT NULL and several other non-relevant columns. I'm trying to map the Family collection to the PERSON table using the FamilyId column, which is not the PK as mentioned above. So, i actually have a one-to-many which is self-table-referential. I'm getting an error saying 'Cast is not valid' when my mapping looks like this: ... <set name="Family" table="Person" lazy="false"> <key column="FamilyId" /> <one-to-many class="Person" /> </set> ... because obviously, the join NHibernate is trying to make is between the PK column, Id, and the 'secondary' column, FamilyId, instead of joining the FamilyId column to itself. Any ideas please?

• Create a dynamic project template in VS 2010?

  - by jonhobbs

  This might sound a bit of an odd question but I know what I want to achieve, just don't know if it's possible. Firstly, I'd like to be able to create a visual studio project that the 2 developers that work with me can use as a basis for all new websites. I want to drop all the common files that we use in there, like jQuery, CMS files etc. so that every time they start a new project they don't have to worry about all of that stuff. I guess to do this I just set up a project and "File Export Template" ? Now, here's the tricky bit... When you open up one of the default templates in VS it asks you a few questions, such as if you want to use a master page or if you want to use code behind etc. What I would like to do is set up something similar so that when you use the project template it asks you what version of jQuery you want to use so that it can import the right file, or for example it might ask you if you want to include certain user controls that the CMS contains. If you tick the box then the folder with the necessary user controls would be put in your new project for you. I know MS can do this but can a user like me include functionality like that in my own project template? Hope that makes sense.

• Splitting an image in GWT results in unwanted white space

  - by rancidfishbreath

  I am using GWT 2.03 and am have an image that I want to place partially in an area with a background and partially above a background. I am using a FlexTable to try to accomplish this and have used GIMP to cut the image into two sections. I am trying to load the top part of the image into row 0 and the bottom part of the image into row 1. I set the alignment of the top image to ALIGN_BOTTOM but there is a bit of space at the bottom of cell and so the two parts of the picture don't touch. Here is an image showing what I am talking about. I set the background of the cell to be yellow show where the cell boundaries are. The bottom image and background are rendering correctly. Here is the relevant code snippet: FlexTable table = new FlexTable(); table.setCellSpacing(0); table.setCellPadding(0); table.setBorderWidth(0); FlexCellFormatter formatter = table.getFlexCellFormatter(); table.setWidget(0, 0, topImage); formatter.setStyleName(0, 0, "topImageStyle"); formatter.setVerticalAlignment(0, 0, HasVerticalAlignment.ALIGN_BOTTOM); table.setWidget(1, 0, bottomImage); formatter.setStyleName(1, 0, "bottomImageStyle"); How can I get rid of that space between my image and the cell boundary?

• CakePHP passing parameters to action

  - by iancocco

  Hi im kinda new in cakephp and having a lot of trouble adjusting.. Here's my biggest problem .. Im trying to pass a parameter to an action, it does load, but when my script goes from the controller to the view, and goes back to the controller again, its gone. CONTROLLER CODE function add($mac = 0) { if(isset($this->params['form']['medico'])) { $temp= $this->Person->find('first', array('conditions' => array('smartphones_MAC' => $mac))); $id= $temp['Person']['id']; $this->Union->set('events_id', $id+1); $this->Union->set('people_id', $id); $this->Union->save(); } VIEW CODE (This is a menu, i only have one button right now) <fieldset> <legend>SELECCIONE SU ALERTA</legend> <?php echo $form->create('Event'); echo $form->submit('EMERGENCIA MEDICA',array('name'=>'medico')); echo $form->end(); ?> </fieldset>

• Why isn't my UITableView appearing in the correct scroll position?

  - by zbrimhall

  I have a split view-based app that presents a master-detail interface, and uses a popover to present the master list when in portrait mode. The popover presents a sectioned table view that ultimately gets populated by a subclass of NSFetchedResultsController. I can tap the tool bar button to present the master list, scroll to whatever row, and tap the row to dismiss the popover. My problem is that if the table is scrolled past the top of the second section, when I dismiss the popover and then later tap the toolbar button to re-present it, the table's scroll position is always set such that the first row of the second section is at the top of the list. If I haven't scrolled past the top of the second section, it correctly remembers its scroll position when the table is presented again. Similarly, in landscape mode, if I scroll the table past the top of the third section and then rotate to portrait, when I come back to landscape the scroll position is always set such that the first row of the third section is at the top of the list. I tried calling -scrollToNearestSelectedRowAtScrollPosition:animated in both the master view controller's -viewWillAppear, as well as in the split view delegate's splitViewController:popoverController:willPresentViewController:, to no effect. Anybody have a clue what I might be doing wrong?

• Why does findstr not handle case properly (in some circumstances)?

  - by paxdiablo

  While writing some recent scripts in cmd.exe, I had a need to use findstr with regular expressions - customer required standard cmd.exe commands (no GnuWin32 nor Cygwin nor VBS nor Powershell). I just wanted to know if a variable contained any upper-case characters and attempted to use: > set myvar=abc > echo %myvar%|findstr /r "[A-Z]" abc > echo %errorlevel% 0 When %myvar% is set to abc, that actually outputs the string and sets errorlevel to 0, saying that a match was found. However, the full-list variant: > echo %myvar%|findstr /r "[ABCDEFGHIJKLMNOPQRSTUVWXYZ]" > echo %errorlevel% 1 does not output the line and it correctly sets errorlevel to 1. In addition: > echo %myvar%|findstr /r "^[A-Z]*$" > echo %errorlevel% 1 also works as expected. I'm obviously missing something here even if it's only the fact that findstr is somehow broken. Why does the first (range) regex not work in this case? And yet more weirdness: > echo %myvar%|findstr /r "[A-Z]" abc > echo %myvar%|findstr /r "[A-Z][A-Z]" abc > echo %myvar%|findstr /r "[A-Z][A-Z][A-Z]" > echo %myvar%|findstr /r "[A]" The last two above also does not output the string!!

• Getting jQuery to return an ajax object

  - by japancheese

  Hello, The question title is a bit strange because I'm not exactly sure how to phrase the problem. The issue is that I have many links to which I want to bind a click event with an ajax call, and I'm just looking to refactor some duplicate code into a single area. The links I'm trying to bind an ajax call only have one thing that differentiates them, and that's an id from a previously declared object. So I have lots of code that looks like this: $("a.link").bind('click', function() { id = obj.id; $.ajax({ url: "/set/" + id, dataType: 'json', type: "POST" }) }); I was trying to refactor it into something like this: $("a.link").bind('click', ajax_link(obj.id)); function ajax_link(id) { $.ajax({ url: "/set/" + id, dataType: 'json', type: "POST" }) }); However, as you can imagine, this just actually makes the ajax call when the element is binded with the click event. Is there an easy way to refactor this code so I can extract out the common ajax code into its own function, and hopefully reduce the number of lines of jQuery in my current script?

• Change default polymorphism in Hibernate

  - by Sujee

  Hi, I'd like to set polymorphism="explicit" property to several hibernate mapping classes. is it possible to override the default implicit value, so that I do not need to set explicit in multiple classes? <class name="xxxxx" table="XXXXX" polymorphism="explicit"> I am using hibernate mapping xml files (No annotations or JPA) and it was loaded by Spring as follows, <bean id="xxxsessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource"> <ref bean="xxxDataSource"/> </property> <property name="mappingResources"> <list> <value>xxx.hbm.xml</value> -------- -------- </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop> ---- ---- </props> </property> </bean> Thank you.

• Core Data: Inverse relationship only mirrors when I edit the mutableset. Not sure why.

  - by zorn

  My model is setup so Business has many clients, Client has one business. Inverse relationship is setup in the mom file. I have a unit test like this: - (void)testNewClientFromBusiness { PTBusiness *business = [modelController newBusiness]; STAssertTrue([[business clients] count] == 0, @"is actually %d", [[business clients] count]); PTClient *client = [business newClient]; STAssertTrue([business isEqual:[client business]], nil); STAssertTrue([[business clients] count] == 1, @"is actually %d", [[business clients] count]); } I implement -newClient inside of PTBusiness like this: - (PTClient *)newClient { PTClient *client = [NSEntityDescription insertNewObjectForEntityForName:@"Client" inManagedObjectContext:[self managedObjectContext]]; [client setBusiness:self]; [client updateLocalDefaultsBasedOnBusiness]; return client; } The test fails because [[business clients] count] is still 0 after -newClient is called. If I impliment it like this: - (PTClient *)newClient { PTClient *client = [NSEntityDescription insertNewObjectForEntityForName:@"Client" inManagedObjectContext:[self managedObjectContext]]; NSMutableSet *group = [self mutableSetValueForKey:@"clients"]; [group addObject:client]; [client updateLocalDefaultsBasedOnBusiness]; return client; } The tests passes. My question(s): So am I right in thinking the inverse relationship is only updated when I interact with the mutable set? That seems to go against some other Core Data docs I've read. Is the fact that this is running in a unit test without a run loop have anything to do with it? Any other troubleshooting recommendations? I'd really like to figure out why I can't set up the relationship at the client end.

• python histogram one-liner

  - by mykhal

  there are many ways, how to code histogram in Python. by histogram, i mean function, counting objects in an interable, resulting in the count table (i.e. dict). e.g.: >>> L = 'abracadabra' >>> histogram(L) {'a': 5, 'b': 2, 'c': 1, 'd': 1, 'r': 2} it can be written like this: def histogram(L): d = {} for x in L: if x in d: d[x] += 1 else: d[x] = 1 return d ..however, there are much less ways, how do this in a single expression. if we had "dict comprehensions" in python, we would write: >>> { x: L.count(x) for x in set(L) } but we don't have them, so we have to write: >>> dict([(x, L.count(x)) for x in set(L)]) however, this approach may yet be readable, but is not efficient - L is walked-through multiple times, so this won't work for single-life generators.. the function should iterate well also through gen(), where: def gen(): for x in L: yield x we can go with reduce (R.I.P.): >>> reduce(lambda d,x: dict(d, x=d.get(x,0)+1), L, {}) # wrong! oops, does not work, the key name is 'x', not x :( i ended with: >>> reduce(lambda d,x: dict(d.items() + [(x, d.get(x, 0)+1)]), L, {}) (in py3k, we would have to write list(d.items()) instead of d.items(), but it's hypothethical, since there is no reduce there) please beat me with a better one-liner, more readable! ;)

• Setting objects (not users) inactive after period of time in asp.net mvc

  - by bastijn

  This question is mainly to verify my current idea. I have a series of objects which I want to be active for a specified amount of time. For instance objects like ads which are shown in the ad space only for the amount of time bought, objects in search results which should only pop up when active, and frontpage posts which should be set to inactive after a prespecified time. My current idea is to just give those type of objects a StartDate and EndDate and filter the search routines to only show results which fall in the range StartDate < currentDate < EndDate. Is this the normal structure or should there be some sort of auto-routine which routinely checks for objects which are "over-time" and set a property "inactive" to true or something. Seems like this approach is such a hassle since I need a checker which runs say, every 5 minutes, to scan all DB objects. Seems like a bad idea to me. So is the first structure the most commonly used or are there any other options? When searching on google or SO the search queries only return results setting users inactive.

• Databinding to Classmember of Classmember

  - by Walter

  Hello, I need some help about WPF and Databinding. Let's say I have a ClassA with a member of ClassB. ClassB has again a member, maybe an int: ClassB { public int MemberOfB { get; set; } } ClassA { private ClassB _theB; public ClassB MemberOfA { get {return _theB;} set { _theB = value; // Need to do something here... } } } When I have a Databinding in XAML like this: <TextBox Text="{Binding Path=MemberOfA.MemberOfB}"/> Where the Datacontext of the Textbox is an object of type ClassA. As you can see, i need to do some computations in the setter of MemberOfA in ClassA. But with the databinding above, this setter is of course never called, because it binds to the member of ClassB. So, how can i get to be informed if the MemberOfA changes (when I Type something into the Textbox)? Are there any best practices? (Didn't check the code in Visual Studio, so there may be some syntax errors). Thanks, Walter

• How make this special many2many fields validation using Django ORM?

  - by e-satis

  I have the folowing model: class Step(models.Model): order = models.IntegerField() latitude = models.FloatField() longitude = models.FloatField() date = DateField(blank=True, null=True) class Journey(models.Model): boat = models.ForeignKey(Boat) route = models.ManyToManyField(Step) departure = models.ForeignKey(Step, related_name="departure_of", null=True) arrival = models.ForeignKey(Step, related_name="arrival_of", null=True) I would like to implement the following check: # If a there is less than one step, raises ValidationError. routes = tuple(self.route.order_by("date")) if len(routes) <= 1: raise ValidationError("There must be at least two setps in the route") # save the first and the last step as departure and arrival self.departure = routes[0] self.arrival = routes[-1] # departure and arrival must at least have a date if not (self.departure.date or self.arrival.date): raise ValidationError("There must be an departure and an arrival date. " "Please set the date field for the first and last Step of the Journey") # departure must occurs before arrival if not (self.departure.date > self.arrival.date): raise ValidationError("Departure must take place the same day or any date before arrival. " "Please set accordingly the date field for the first and last Step of the Journey") I tried to do that by overloading save(). Unfortunately, Journey.route is empty in save(). What's more, Journey.id doesn't exists yet. I didn't try django.db.models.signals.post_save but suppose it will fail because Journey.route is empty as well (when does this get filled anyway?). I see a solution in django.db.models.signals.m2m_changed but there are a lot of steps (thousands), and I want to avoid to perform an operation for every single of them.

• how to join tables sql server

  - by Rick

  Im having some trouble with joining two tables. This is what my two tables look like: Table 1 Customer_ID CustomerName Add. 1000 John Smith 1001 Mike Coles 1002 Sam Carter Table 2 Sensor_ID Location Temp CustIDFK 1000 NY 70 1002 NY 70 1000 ... ... 1001 1001 1002 Desired: Sensor_ID Location Temp CustIDFK 1000 NY 70 John Smith 1002 NY 70 Sam Carter 1000 ... ... John Smith 1001 Mike Coles 1001 1002 I have made Customer_ID from table 1 my primary key, created custIDFK in table 2 and set that as my foreign key. I am really new to sql server so I am still having trouble with the whole relationship piece of it. My goal is to match one customer_ID with one Sensor_ID. The problem is that the table 2 does not have "unique IDs" since they repeat so I cant set that to my foreign key. I know I will have to do either an inner join or outer join, I just dont know how to link the sensor id with customer one. I was thinking of giving my sensor_ID a unique ID but the data that is being inserted into table 2 is coming from another program. Any suggestions?

• Query notation for the sitecore 'source' field in template builder

  - by M.R.

  I am trying to set the the source field of a template using the query notation (or xpath - whichever works), but none of them seems to be working. My content tree is a multisite content tree: France --Page 1 ----Page1A -------Page1AA --Page 2 --Page 3 --METADATA ----Regions US --Page 1 ----Page1A -------Page1AA --Page 2 --Page 3 --METADATA ----Regions Each site has its own METADATA folder, and I want it so that when adding a page inside each of the main country nodes, I want the values to reflect whatever is in the METADATA of that site. I have two different fields for now - a droplink and a treelistex field. So I thought I can just get the parent item that is a country site, and get the metadata folder for that. When I put the following query in both the fields, I get different results: query:./ancestor::*[@@templatename='CountryHome']/METADATA/Regions/* For the droplink field, I get only the first Region (one item) For the treelistex field, I get the entire content tree I then tried to modify the query a little bit and took the 'query' notation out ./ancestor::*[@@templatename='CountryHome']/METADATA/Regions/* If I go to the developer center/xpath builder, and set the context node to any item underneath the main country site, it returns me exactly what I need, but when I put this in the source, I get the entire content tree in both the cases. Help!

• Multithreaded IOCP Client Issue

  - by Carl

  I am writing a multithreaded client that uses an IO Completion Port. I create and connect the socket that has the WSA_FLAG_OVERLAPPED attribute set. if ((m_socket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP)) == INVALID_SOCKET) { throw std::exception("Failed to create socket."); } if (WSAConnectByName(m_socket, L"server.com", L"80", &localAddressLength, reinterpret_cast<sockaddr*>(&localAddress), &remoteAddressLength, &remoteAddress, NULL, NULL) == FALSE) { throw std::exception("Failed to connect."); } I associate the IO Completion Port with the socket. if ((m_hIOCP = CreateIoCompletionPort(reinterpret_cast<HANDLE>(m_socket), m_hIOCP, NULL, 8)) == NULL) { throw std::exception("Failed to create IOCP object."); } All appears to go well until I try to send some data over the socket. SocketData* socketData = new SocketData; socketData->hEvent = 0; DWORD bytesSent = 0; if (WSASend(m_socket, socketData->SetBuffer(socketData->GenerateLoginRequestHeader()), 1, &bytesSent, NULL, reinterpret_cast<OVERLAPPED*>(socketData), NULL) == SOCKET_ERROR && WSAGetLastError() != WSA_IO_PENDING) { throw std::exception("Failed to send data."); } Instead of returning SOCKET_ERROR with the last error set to WSA_IO_PENDING, WSASend returns immediately. I need the IO to pend and for it's completion to be handled in my thread function which is also my worker thread. unsigned int __stdcall MyClass::WorkerThread(void* lpThis) { } I've done this before but I don't know what is going wrong in this case, I'd greatly appreciate any efforts in helping me fix this problem.

• Replace System.Net.Mail.MailMessage with manually created message and send it

  - by DEH

  I am trying to send emails that will bounce to a known mailbox. I plan to use VERP. Unfortunately the System.Net.Mail.MailMessage object does not allow me to precisely set the From: and Sender: headers within my email - it forces the values so that the resulting email contains the phrase 'on behalf of', and does not allow me fine control over the relevant mime headers. I therefore plan to manually write mime email messages directly to the pickup directory so that I can independently control the From and Sender headers. My dev box is a Vista box and therefore does not have an SMTP server. I would like to configure the dev box so that I have an SMTP server running on it. I can then turn off the SMTP server, write messages to the pickup dir, then turn on the SMPT server and see how the individual emails that I have written will behave (some delivered, some bounced to a bounce handler on a different email domain, as dictated by the Sender). Two questions: 1. Can anyone recommend an SMTP server that will monitor a pickup directory? 2. If I set headers as follows; From:[email protected]; Sender:[email protected] then the recipient will see the email as having come from [email protected] ( and won't see any reference to [email protected]), but if the mail bounces then the NDR will be sent to [email protected]). It's a real pain to have to do this, but I can't see any way of using System.Net.Mail.MailMessage without it messing up my headers.

• Setting up a pc bluetooth server for android

  - by Del

  Alright, I've been reading a lot of topics the past two or three days and nothing seems to have asked this. I am writing a PC side server for my andriod device, this is for exchanging some information and general debugging. Eventually I will be connecting to a SPP device to control a microcontroller. I have managed, using the following (Android to pc) to connect to rfcomm channel 11 and exchange data between my android device and my pc. Method m = device.getClass().getMethod("createRfcommSocket", new Class[] { int.class }); tmp = (BluetoothSocket) m.invoke(device, Integer.valueOf(11)); I have attempted the createRfcommSocketToServiceRecord(UUID) method, with absolutely no luck. For the PC side, I have been using the C Bluez stack for linux. I have the following code which registers the service and opens a server socket: int main(int argc, char **argv) { struct sockaddr_rc loc_addr = { 0 }, rem_addr = { 0 }; char buf[1024] = { 0 }; char str[1024] = { 0 };

• Removing a view from it's superview causes memory error - why?

  - by mystify

  Xcode is throwing an error at me: malloc: * error for object 0x103f000: pointer being freed was not allocated * set a breakpoint in malloc_error_break to debug I tracked down the code until a line where I do this: - (void)inputValueCommitted:(NSString *)animationID finished:(BOOL)finished context:(void *)context { // retainCount of myView is 2! (one for the retain-property, one for beeing a subview) [self.myView removeFromSuperview]; // ERROR-LINE !! self.myView = nil; } When I remove that errorful line, the error is gone. So in conclusion: I can't get rid of my view! It's an UIImageView with nothing else inside, just showing an image. What I do is this: I create an UIView Animation Block, create that UIImageView, assign it to an retain-property with self.myView = ..., and after the animation is done, I just want to get rid of that view. So I remove it from it's superview and then set my property to nil, which lets it go away - in theory. Did anyone else encounter such issues? iPhone SDK 3.0.

• Techniques for sharing a value among classes in a program

  - by Kenneth Cochran

  I'm using Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) + "\MyProgram" As the path to store several files used by my program. I'd like to avoid pasting the same snippet of code all over the my applcation. I need to ensure that: The path cannot be accidentally changed once its been set The classes that need it have access to it. I've considered: Making it a singleton Using constructor dependency injection Using property dependency injection Using AOP to create the path where its needed. Each has pros and cons. The singleton is everyone's favorite whipping boy. I'm not opposed to using one but there are valid reasons to avoid it if possible. I'm already heavily using constructor injection through Castle Windsor. But this is a path string and Windsor doesn't handle system type dependencies very gracefully. I could always wrap it in a class but that seems like overkill for something as simple as a passing around a string value. In any case this route would add yet another constructor argument to each class where it is used. The problem I see with property injection in this case is that there is a large amount of indirection from the where the value is set to where it is needed. I would need a very long line of middlemen to reach all the places where its used. AOP looks promising and I'm planning on using AOP for logging anyway so this at least sounds like a simple solution. Is there any other options I haven't considered? Am I off base with my evaluation of the options I have considered?

• How to use the Request URL/URL Rewriting For Localization in ASP.NET - Using an HTTP Module or Globa

  - by LocalizedUrlDMan

  I wanted to see if there is a way to use the request URL/URL rewriting to set the language a page is rendered in by examining a portion of the URL in ASP.NET. We have a site that already works with ASP.NET’s resource localization and user’s can change the language that they see pages/resources on the site in, however the current mechanism in not very search engine friendly since the language variations for each language all appear as one page. It would be much better if we could have pages like www.site.com/en-mx/realfolder/realpage.aspx that allow linking to culture specific versions of a page. I know lots of people have likely done localization through URL structures before and I wanted to know if one of your could share how to do this in the Global.asax file or with an HTTP Module (pointing to links to blog postings would be great too). We have a restriction that the site is based on ASP.NET 2.0 (so we can't used the 3.5+ features yet). Here is the example scenario: A real page exits at: www.site.com/realfolder/realpage.aspx The page has a mechanism for the user to change the language it is displayed in via a dropdown. There are search engine optimization and user links sharing benefits to doing this since people can link directly to a page that has content that is applicable to a certain language (this could also include right-to-left layouts for languages like Japanese). I would like to use an HTTP module to see if the first part of the URL after www.site.com, site.com, subdomain.site.com, etc. contains a valid culture code (e.g. en-us, es-mx) then use that value to set the localization culture of the page/resources based on that URL. So if the user accesses the URL www.site.com/en-MX/realfolder/realpage.aspx Then the page will render in Mexico’s variant of Spanish. If the user goes to www.site.com/realfolder/realpage.aspx directly the page would just use their browser’s language settings.

• How to customize the content of each page using Page Control and UIScrollView?

  - by viper15

  I have problem with customizing each page using pagecontrol and UIScrollView. I'm customizing Page Control from Apple. Basically I would like to have each page different with text and image alternately on different page. Page 1 will have all text, Page 2 will have just images, Page 3 will have all text and goes on. This is original code: // Set the label and background color when the view has finished loading. - (void)viewDidLoad { pageNumberLabel.text = [NSString stringWithFormat:@"Page %d", pageNumber + 1]; self.view.backgroundColor = [MyViewController pageControlColorWithIndex:pageNumber]; } As you can see, this code shows only Page 1, Page 2 etc as you scroll right. I tried to put in this new code but that didn't make any difference. There's no error. I know this is pretty simple code. I don't why it doesn't work. I declare pageText as UILabel. // Set the label and background color when the view has finished loading. - (void)viewDidLoad { pageNumberLabel.text = [NSString stringWithFormat:@"Page %d", pageNumber + 1]; self.view.backgroundColor = [MyViewController pageControlColorWithIndex:pageNumber]; if (pageNumber == 1) { pageText.text = @"Text in page 1"; } if (pageNumber == 2) { pageText.text = @"Image in page 2"; } if (pageNumber == 3) { pageText.text = @"Text in page 3"; } } I don't know why it doesn't work. Also if you have better way to do it, let me know. Thanks.

• How to compile Open Flash Chart v.1?

  - by geehertush01

  Let me just say, that I'm a total beginner in anything related to flash. I would like to compile latest version of OFC1 (v.1.9.7). It can be downloaded here: link. Unfortunately no tutorial of how to do it can be found anywhere. I succeeded in compiling OFC2 (v.Lug-Wyrm-Charmer). I installed FlashDevelop, then I found .proj file in the OFC2 package, opened it in FlashDevelop and built the project. It worked fine (although I had to fix some code errors, but it was simple). Unfortunately there is no project file in OFC1 package. I tried to create a new project (Project-New Project-AS3 Project). It created .proj file and few folders (src,bin...). I deleted 'Main.as' from 'src' folder. Then I copied all files from 'actionscript' folder from OFC1 to 'src' project folder. I opened the project and set 'open-flash-char.as' as Document Class (right click on the file in the project tree and 'Set Document Class'). Then I tried to build the project, but got an syntax error with (in 'open-flash-char.as'): #include "prototype.drawCircle.as" #include "prototype.fillCircle.as" #include "String.prototype.replace.as" So I removed "#" signs. But then I got an error ...\ofc1\projtest4\src\open-flash-chart.as: Error: A file found in a source-path must have an externally visible definition. If a definition in the file is meant to be externally visible, please put the definition in a package. I have no idea of how to continue. Maybe I'm doing everything wrong, because OFC1 is written in AS2 (probably), not AS3. I don't know. So my question is: How to compile OFC v.1.9.7?

• Setting Position of source and listener has no effect

  - by Ben E

  Hi Guys, First time i've worked with OpenAL, and for the life of my i can't figure out why setting the position of the source doesn't have any effect on the sound. The sounds are in stero format, i've made sure i set the listener position, the sound is not realtive to the listener and OpenAL isn't giving out any error. Can anyone shed some light? Create Audio device ALenum result; mDevice = alcOpenDevice(NULL); if((result = alGetError()) != AL_NO_ERROR) { std::cerr << "Failed to create Device. " << GetALError(result) << std::endl; return; } mContext = alcCreateContext(mDevice, NULL); if((result = alGetError()) != AL_NO_ERROR) { std::cerr << "Failed to create Context. " << GetALError(result) << std::endl; return; } alcMakeContextCurrent(mContext); SoundListener::SetListenerPosition(0.0f, 0.0f, 0.0f); SoundListener::SetListenerOrientation(0.0f, 0.0f, -1.0f); The two listener functions call alListener3f(AL_POSITION, x, y, z); Real vec[6] = {x, y, z, 0.0f, 1.0f, 0.0f}; alListenerfv(AL_ORIENTATION, vec); I set the sources position to 1,0,0 which should be to the right of the listener but it has no effect alSource3f(mSourceHandle, AL_POSITION, x, y, z); Any guidance would be much appreciated

• Design suggestion for expression tree evaluation with time-series data

  - by Lirik

  I have a (C#) genetic program that uses financial time-series data and it's currently working but I want to re-design the architecture to be more robust. My main goals are: sequentially present the time-series data to the expression trees. allow expression trees to access previous data rows when needed. to optimize performance of the data access while evaluating the expression trees. keep a common interface so various types of data can be used. Here are the possible approaches I've thought about: I can evaluate the expression tree by passing in a data row into the root node and let each child node use the same data row. I can evaluate the expression tree by passing in the data row index and letting each node get the data row from a shared DataSet (currently I'm passing the row index and going to multiple synchronized arrays to get the data). Hybrid: an immutable data set is accessible by all of the expression trees and each expression tree is evaluated by passing in a data row. The benefit of the first approach is that the data row is being passed into the expression tree and there is no further query done on the data set (which should increase performance in a multithreaded environment). The drawback is that the expression tree does not have access to the rest of the data (in case some of the functions need to do calculations using previous data rows). The benefit of the second approach is that the expression trees can access any data up to the latest data row, but unless I specify what that row is, I'll have to iterate through the rows and figure out which one is the last one. The benefit of the hybrid is that it should generally perform better and still provide access to the earlier data. It supports two basic "views" of data: the latest row and the previous rows. Do you guys know of any design patterns or do you have any tips that can help me build this type of system? Should I use a DataSet to hold and present the data, or are there more efficient ways to present rows of data while maintaining a simple interface? FYI: All of my code is written in C#.
