    - by vasion
    I am finding it hard to fugure out the reference system in AS 3.0. this is the code i have (i have trimmed it down in order to find the problem but to no avail) package rpflash.ui { import flash.display.Sprite; import flash.display.MovieClip; import flash.display.Stage; import nowplaying; import flash.text.TextField; public class RPUserInterface extends Sprite{ var np:nowplaying; public function RPUserInterface(){ } public function init(){ var np:nowplaying = new nowplaying(); this.addChild(np) } public function updateplayer(xml:XML){ var artist: String = xml.nowplaying.artist.toString(); var title: String = xml.nowplaying.title.toString(); trace("UI:update"); trace(this.np);// this gives me a null reference } } } and still i cannot access np!!! trace this.np gives me a null reference. i am not even trying to access it from a subling class. (btw i def want to know how to do that as well.)

  • Problem using Hibernate-Search

    - by KCore
    Hi, I am using hibernate search for my application. It is well configured and running perfectly till some time back, when it stopped working suddenly. The reason according to me being the number of my model (bean) classes. I have some 90 classes, which I add to my configuration, while building my Hibernate Configuration. When, I disable hibernate search (remove the search annotations and use Configuration instead of AnnotationsConfiguration), I try to start my application, it Works fine. But,the same app when I enable search, it just hangs up. I tried debugging and found the exact place where it hangs. After adding all the class to my AnnotationsConfiguration object, when I say cfg.buildSessionfactory(), It never comes out of that statement. (I have waited for hours!!!) Also when I decrease the number of my model classes (like say to half i.e. 50) it comes out of that statement and the application works fine.. Can Someone tell why is this happening?? My versions of hibernate are: hibernate-core-3.3.1.GA.jar hibernate-annotations-3.4.0.GA.jar hibernate-commons-annotations-3.1.0.GA.jar hibernate-search-3.1.0.GA.jar Also if need to avoid using AnnotationsConfiguration, I read that I need to configure the search event listeners explicitly.. can anyone list all the neccessary listeners and their respective classes? (I tried the standard ones given in Hibernate Search books, but they give me ClassNotFound exception and I have all the neccesarty libs in classpath) Here are the last few lines of hibernate trace I managed to pull : 16:09:32,814 INFO AnnotationConfiguration:369 -

  • How to upgrade the project build in visual studio 2005 to visual studio 2008?

    - by Shailesh Jaiswal
    I have one OPC ( OLE for Process control ) server project which is developed into visual studio 2005. I want to run it in visual studio 2008. The coding for the OPC server project is done in VC++. I want to connect my OPC client to this OPC server. When I was opened the OPC server project which was build into visual studio 2005 into visual studio 2008 first time it was asking for conversion wizard. I gone through that wizard & successfully finished that wizard. But when I build ( by right clicking on the project & choosing build solution ) it is giving lots of error near about 64 errors. Most of the errors are like - fetal error C1083:Can not open type library file:'msxml4.dll':No such file or directory, fetal error LINK1181:can not open input file 'rpcndr.lib' , error C2051:case expression not constant. only these 3 types of errors in am getting. All these 3 errors are repeated in Error list & becoming bunch of 64 errors. Please provide me the solution for the above issue. Can you provide me any suusgestion or link or any way through whcih I can resolve the above issue?

  • SQLAlchemy unsupported type error - and table design issues?

    - by Az
    Hi there, back again with some more SQLAlchemy shenanigans. Let me step through this. My table is now set up as so: engine = create_engine('sqlite:///:memory:', echo=False) metadata = MetaData() students_table = Table('studs', metadata, Column('sid', Integer, primary_key=True), Column('name', String), Column('preferences', Integer), Column('allocated_rank', Integer), Column('allocated_project', Integer) ) metadata.create_all(engine) mapper(Student, students_table) Fairly simple, and for the most part I've been enjoying the ability to query almost any bit of information I want provided I avoid the error cases below. The class it is mapped from is: class Student(object): def __init__(self, sid, name): self.sid = sid self.name = name self.preferences = collections.defaultdict(set) self.allocated_project = None self.allocated_rank = 0 def __repr__(self): return str(self) def __str__(self): return "%s %s" %(self.sid, self.name) Explanation: preferences is basically a set of all the projects the student would prefer to be assigned. When the allocation algorithm kicks in, a student's allocated_project emerges from this preference set. Now if I try to do this: for student in students.itervalues(): session.add(student) session.commit() It throws two errors, one for the allocated_project column (seen below) and a similar error for the preferences column: sqlalchemy.exc.InterfaceError: (InterfaceError) Error binding parameter 4 - probably unsupported type. u'INSERT INTO studs (sid, name, allocated_rank, allocated_project) VALUES (?, ?, ?, ?, ?, ?, ?)' [1101, 'Muffett,M.', 1, 888 Human-spider relationships (Supervisor id: 123)] If I go back into my code I find that, when I'm copying the preferences from the given text files, it actually refers to the Project class which is mapped to a dictionary, using the unique project id's (pid) as keys. Thus, as I iterate through each student via their rank and to the preferences set, it adds not a project id, but the reference to the project id from the projects dictionary. students[sid].preferences[int(rank)].add(projects[int(pid)]) Now this is very useful to me since I can find out all I want to about a student's preferred projects without having to run another check to pull up information about the project id. The form you see in the error has the object print information passed as: return "%s %s (Supervisor id: %s)" %(self.proj_id, self.proj_name, self.proj_sup) My questions are: I'm trying to store an object in a database field aren't I? Would the correct way then, be copying the project information (project id, name, etc) into its own table, referenced by the unique project id? That way I can just have the project id field for one of the student tables just be an integer id and when I need more information, just join the tables? So and so forth for other tables? If the above makes sense, then how does one maintain the relationship with a column of information in one table which is a key index on another table? Does this boil down into a database design problem? Are there any other elegant ways of accomplishing this? Apologies if this is a very long-winded question. It's rather crucial for me to solve this, so I've tried to explain as much as I can, whilst attempting to show that I'm trying (key word here sadly) to understand what could be going wrong.

  • What Can A 'TreeDict' (Or Treemap) Be Used For In Practice?

    - by Seun Osewa
    I'm developing a 'TreeDict' class in Python. This is a basically a dict that allows you to retrieve its key-value pairs in sorted order, just like the Treemap collection class in Java. I've implemented some functionality based on the way unique indexes in relational databases can be used, e.g. functions to let you retrieve values corresponding to a range of keys, keys greater than, less than or equal to a particular value in sorted order, strings or tuples that have a specific prefix in sorted order, etc. Unfortunately, I can't think of any real life problem that will require a class like this. I suspect that the reason we don't have sorted dicts in Python is that in practice they aren't required often enough to be worth it, but I want to be proved wrong. Can you think of any specific applications of a 'TreeDict'? Any real life problem that would be best solved by this data structure? I just want to know for sure whether this is worth it.

  • Returning a complex data type from arguments with Rhino Mocks

    - by Joseph
    I'm trying to set up a stub with Rhino Mocks which returns a value based on what the parameter of the argument that is passed in. Example: //Arrange var car = new Car(); var provider= MockRepository.GenerateStub<IDataProvider>(); provider.Stub( x => x.GetWheelsWithSize(Arg<int>.Is.Anything)) .Return(new List<IWheel> { new Wheel { Size = ?, Make = Make.Michelin }, new Wheel { Size = ?, Make = Make.Firestone } }); car.Provider = provider; //Act car.ReplaceTires(); //Assert that the right tire size was used when replacing the tires The problem is that I want Size to be whatever was passed into the method, because I'm actually asserting later that the wheels are the right size. This is not to prove that the data provider works obviously since I stubbed it, but rather to prove that the correct size was passed in. How can I do this?

  • xslt and xpath: match preceding comments

    - by miasbeck
    given this xml: <root> <list> <!-- foo's comment --> <item name="foo" /> <item name="bar" /> <!-- another foo's comment --> <item name="another foo" /> </list> </root> I'd like to use a XPath to select all item-nodes that have a comment immediately preceding them, that is I like to select the "foo" and "another foo" items, but not the "bar" item. I already fiddled about the preceding-sibling axis and the comment() function but to no avail.

  • Execute codes in a different page but remain on the same actual php page

    - by chupinette
    I have a complicated problem here..I have codes to send mail using PEAR which i have tested in a php page called testmail.php. Now i have my actual application an a page called Cart.php where i have a button called Place Order. When i click on this button, it actually redirects to a url called : http://localhost/final/index.php?OrderSuccessful which actually displays a message on the page and sends an email. The problem is that when i put the code for email in Cart.php, i get errors. But when i put the url http://localhost/final/testmail.php it actually works. So i was thinking, is there a way to execute the codes from that testmail.php by remaining on the page Cart.php? include('Mail.php'); $mail = Mail::factory("mail"); $headers = array("From"=>"[email protected]", "Subject"=>"Your order has been placed "); $body = "lol"; $mail->send("[email protected]", $headers, $body); I get the error Assigning the return value of new by reference is deprecated

  • Sendmail not working from local PHP when headers not specified

    - by Dan
    Hi. I'm having trouble getting my local XAMPP server to send emails via my remote SMTP server. In PHP, if I put: $headers = "From: [email protected]\r\n"; mail('[email protected]', 'test', '', $headers); Then this works. However, if I don't specify the header, ie.: mail('[email protected]', 'test', ''); Then this fails. The sendmail.log file says: smtpstatus=554 smtpmsg='554 Message refused.' errormsg='the server did not accept the mail' exitcode=EX_UNAVAILABLE I've tried changing my sendmail command in my php.ini to: sendmail_path = "C:/xampp/sendmail/sendmail.exe -t -f [email protected]" but this doesn't work either. Thanks for any help with this, Dan. ps. this is on windows.

  • Exchange Server 2007 Setup

    - by AlamedaDad
    Hi, I'm working on a upgrade to Exchange 2007 and I wanted to get some advise on hardware choices. We currently have an Exchange 2003 STD server with 400 users split between 6 AD Sites, that is housed on a single server. We need to move to a redundant, fault tolerant system to support our users. I'm planning on installing 2 Dell 1950 servers with W2k8-std to act as CAS and Hub servers, with NLB to allow abstraction of the actual server name to the users. There won't be an edge system since we have a Barracuda box already that will handle in/out spam/virus filtering. Backend I'm planning on 2 mailbox servers which will be Dell 2950s with 16GB RAM, 2 either dual-core or quad-core CPUs and 6 300GB SAS drives in some RAID config. These systems will be clustered using W2k8 Ent clustering and running CCR in Exchange. My questions are as follows: Is 16GB enough RAM for serving that many mailboxes along with the windows clustering and ccr? I'm trying to figure out disk layouts and I'm unsure of whether to use all local disk or some local and some SAN, via an OpenFiler iSCSI server. The SAN would be a Dell 2850 with 6 - 300GB SCSI drives and a PERC controller to slice as I want, with 8GB RAM. Option 1: 2 drives, RAID 1 - OS 2 drives, RAID 1 - Logs 2 drives, RAID 1 - Mail stores Option 2: 2 drives, RAID 1 - OS and logs 4 drives, RAID 5 - Mail Stores and scratch space for eseutil. Option 3: 2 drives, RAID 1 - OS 2 drives, RAID 1 - Logs 2 drives, RAID 0 - scratch space ~300GB iSCSI volume for mail stores Option 4: 2 drives, RAID 1 - OS 4 drives, RAID 5 - scratch space ~300GB iSCSI volume for mail stores ~300GB iSCSI volume for logs I have 2 sockets for CPUs and need to chose between dual and quad cores. The dual core have faster clocks but less cache and I'm thinking older architecture. Am I better off with more cores and cache while sacraficing clock speed? I am planning on adding the new E2K7 cluster to the E2K3 server and then move each mailbox over, all at once, then remove the old server. This seems more complicated than simply getting rid of the 2003 server and then adding the 2007 cluster and restoring the mailboxes using PowerControls or exmerge. The migration option lets me do this on my time, where a cutover means it all needs to work at once. If I go with the cutover method, how can I prebuild the servers and add them to the domain right after removing the 2003 server, or can't I? I think the answer is no and the migration is my only real option if I want to prebuild. I need to also migrate about 30GB of Public Folders. Is there anything special about this, other than specifying in the E2K7 install that I want older Outlook clients and PF's setup? I guess I could even keep the E2K3 server to host just the PFs? Lastly, if I have a mix of Outlook 200, 2003 and 2007 what do I need to do to make sure they all have access to the GAL and OAB? At time of cutover, we'll be at like 90% 2007, but we will have some older stuff around. My plan is to use Outlook Anywhere on laptops that are used outside the physical network. Are there any gotchas involved in that? I'm even thinking about using is for all Outlook clients, does anyone do that? The reason I'm considering it is that our WAN is really VPN tunnels over internet connections, so not a fully messhed, stable WAN. Thank you all very much for the assistance in advance and I look forward to discussion of these points! Regards...Michael

  • Migrated from Exchange 2003 to Exchange 2007 - remove old 03 computer account?

    - by TheCleaner
    Migrated from Exchange 2003 to 2007 back in February of this year. I've still got the old exchange computer account in AD. Can I simply delete the computer account or will bad things start happening? I've looked in the Exchange 07 console and don't see the old server listed at all. HOWEVER: we do still have an old CNAME for this old Exchange server pointing to the new one for a few old clients that still have their mail server set to the old name...if that matters at all. I ran "get-exchangeserver" on the new server and the old one isn't listed at all.
