  • My PowerShell functions do not appear to be used

    - by Frank
    Hi there, I have a ps1 script in which I define 2 functions as such: function Invoke-Sql([string]$query) { Invoke-Sqlcmd -ServerInstance $Server -Database $DB -User $User -Password $Password -Query $query } function Get-Queued { Invoke-Sql "Select * From Comment where AwaitsModeration = 1" } I then call the ps1 file by typing it in (it's in a folder in the path, and autocompletion works) However, I cannot start using the functions. I am confused, because when I copy / paste the functions into the console, all is fine and they work. I also have a function defined in my profile, and it works. Where am I thinking wrong, why doesn't it work what I'm trying to do?

  • UIIMageView, warning: check_safe_call: could not restore current frame

    - by lukya
    Hi, I am changing the image in UIImageView based on accelerometer input. The images are stored in an array. The application runs fine for a while and then crashes. warning: check_safe_call: could not restore current frame I am not using "UIImage ImageNamed" method when populating the array. The total size of all images is around 12 Mb. But individual images are very light (<100 kb) and i am using only one image at a time from the array. Just in case there are any autoreleases, I have allocated a NSAutoreleasePool in view did load and am draining it in the didReceiveMemoryWarning method (which does get called 2, 3 times before the app crashes?). Following is the code that creates images array: //create autorelease pool as we are creating many autoreleased objects NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSMutableArray *finalarr = [[NSMutableArray alloc] initWithCapacity:9]; NSLog(@"start loading"); for(int y = 0; y < 100; y+=10) { NSMutableArray *arr = [[NSMutableArray alloc] initWithCapacity:10]; for(int x = 0; x < 10; x++) { NSString *imageName = [[NSString alloc] initWithFormat:@"0%d",y + x]; UIImage *img = [[UIImage alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:imageName ofType:@"png"]]; [arr addObject:img]; [imageName release]; [img release]; } [finalarr addObject:arr]; [arr release]; } NSLog(@"done loading"); // Override point for customization after app launch viewController.imagesArray = finalarr; [finalarr release]; //retain the array of images [viewController.imagesArray retain]; //release the aurtorelease pool to free memory taken up by objects enqued for release [pool release]; As the app runs smoothly for a while, which means array creation is definitely not the problem. After this the following method is called from [accelerometer didAccelerate] -(BOOL)setImageForX:(int)x andY:(int)y { [self.imageView setImage:(UIImage*)[(NSArray*)[self.imagesArray objectAtIndex:y] objectAtIndex:x]]; return TRUE; } So the only code being executed is the "UIImageView setImage". But no objects are being created here. Please let me know if the code seems to have any leaks or i am doing something wrong. Thanks, Swapnil

  • ListChildren SQL Reporting Service

    - by markpirvine
    Hi, I'm trying to get a list of available reports via the webservice for SQL Reporting Services 2005 express edition. Each time I try to call the ListChildren method I get an insuffient permission exception. The code is: ReportingService2005SoapClient rService = new ReportingService2005SoapClient(); CatalogItem[] cItems = null; rService.ListChildren("/", false, out cItems); I added the ASP.net (iusr) account into the local admin group on the PC and still get the exception. Is this method supported in the express edition? Mark

  • http(/* argument here */) How is this Object (Http) being used without an explicit or implicit meth

    - by Randin
    In the example for coding with Json using Databinder Dispatch Nathan uses an Object (Http) without a method, shown here: import dispatch._ import Http._ Http("http://www.fox.com/dollhouse/" >>> System.out ) How is he doing this? Thank you for all of the answers unfortunatly I was not specific enough... It looks like it is simply passing an argument to a constructor of class or companion object Http. In another example, I've seen another form: http = new Http http(/* argument here */) Is this valid Scala? I guess it must be, because the author is a Scala expert. But it makes no sense to me. Actions are usually performed by invoking methods on objects, whether explicitly as object.doSomething() or implicitly as object = something (using the apply() method underneath the syntactic sugar). All I can think of is that a constructor is being used to do something in addition to constructing an object. In other words, it is having side effects, such as in this case going off and doing something on the web.

  • Flipping PDF pages in QuartzDemo application

    - by BittenApple
    I am working on modifying the quartzdemo application so that it can show another page from a multipage pdf on tap screen event. So far I have stripped it down to the point where it displays the PDF on any page as initial page, but I can't seem to get it figured out how to make the quartzview display anything else then the initial page. I'm guessing that the pushViewController has something to do with this. Anyway, here's my method that draws the initial page and in sits in QuartzImages.m file: -(void)drawNewPage:(CGContextRef)myContext { CGContextTranslateCTM(myContext, 0.0, self.bounds.size.height); CGContextScaleCTM(myContext, 1.0, -1.0); CGContextSetRGBFillColor(myContext, 255, 255, 255, 1); CGContextFillRect(myContext, CGRectMake(0, 0, 320, 412)); CGPDFPageRef page = CGPDFDocumentGetPage(pdfFajl, pageNumber); CGContextSaveGState(myContext); CGAffineTransform pdfTransform = CGPDFPageGetDrawingTransform(page, kCGPDFCropBox, self.bounds, 0, true); CGContextConcatCTM(myContext, pdfTransform); CGContextDrawPDFPage(myContext, page); CGContextRestoreGState(myContext); } This gets fired up in MainViewController.m so: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // ### DISPLAY DESIRED PAGE QuartzViewController *targetViewController = [self controllerAtIndexPath:indexPath]; if ([targetViewController.quartzView isKindOfClass:[QuartzPDFView1 class]]) { ((QuartzPDFView1 *)targetViewController.quartzView).pageNumber = 1; CFURLRef pdfURL = CFBundleCopyResourceURL(CFBundleGetMainBundle(), CFSTR("mypdftest.pdf"), NULL, NULL); ((QuartzPDFView1 *)targetViewController.quartzView).pdfFajl = CGPDFDocumentCreateWithURL((CFURLRef)pdfURL); CFRelease(pdfURL); } [[self navigationController] pushViewController:targetViewController animated:YES]; } Since I'm fairly new to the iPhone development (I'm currently only on page 123 in "beginning iphone 3 development" book) these controllers confuse me as hell. I have setup an event which gets fired up fine on screen tap. The event sits in QuartzView.m and I get a simple alert on screen tap showing that the tap was registered. I would like to use this method to draw a new page instead of showing the alert, page number doesn't matter, I'll work on incrementing (page flipping) later, I need an example of how to call these methods (if its even possible). These are defined in QuartzView.h and I planned on using them in the tap event method: CGPDFDocumentRef pdfFajl; int pageNumber; Thankful for any useful input from "the internets" :)

  • Unable to use Client Application Services with custom MembershipProvider.

    - by Shimmy
    Hi, I have a Windows-Forms Application that I configured to use with an ASP.NET Service that is an Authentication service using a custom MembershipProvider. When I call Membership.CreateUser in the Windows Application a NotSupportedException is thrown telling: "Specified method is not supported.". I tried creating a web page in the website and test the MembershipProvider, everything works just fine when woeking from within the website. Any ideas or link for how to use custom (not SqlMembershipProvider) MembershipProvider will be really appreciated! Edit: The method ValidateUser does work. The overriden CreateUser doesn't work I tried Override Sub CreateUser(.......) As MembershipUser Return New User() End Sub But I still get the same excetption as before.

  • How to prevent "Local transaction already has 1 non-XA Resource" exception?

    - by Zeratul
    Hi, I'm using 2 PU in stateless EJB and each of them is invoked on one method: @PersistenceContext(unitName="PU") private EntityManager em; @PersistenceContext(unitName="PU2") private EntityManager em2; @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW ) public void getCandidates(final Integer eventId) throws ControllerException { ElectionEvent electionEvent = em.find(ElectionEvent.class, eventId); ... Person person = getPerson(candidate.getLogin()); ... } @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW ) private Person getPerson(String login) throws ControllerException { Person person = em2.find(Person.class, login); return person; } Those methods are annotated with REQUIRES_NEW transcaction to avoid this exception. When I was calling these method from javaFX applet, all worked as expected. Now I'm trying to call them from JAX-RS webservice (I don't see any logical difference as in both cases ejb was looked up in initial context) and I keep getting this exception. When I set up XADatasource in glassfish 2.1 connection pools, I got nullpointer exception on em2. Any ideas what to try next? Regards

  • static void classes

    - by ivor
    Hello, I'm tidying up some of my code with the correct scope on some methods and attributes (I have two classes and at the moment I have a number which I just declared as public to get working, but I feel I should look into this and make private where possible, for better practice) When working in eclipse it's suggested on one method, when i change it private from public, that I can fix it by dropping off the scope so the method just says "static void" instead of public/private static void. Is this a better scenario to have nothing, rather than private or public - or is the default scope equivelant to public anyway ? Thanks

  • valueOf() vs. toString() in Javascript

    - by brainjam
    In Javascript every object has a valueOf() and toString() method. I would have thought that the toString() method got invoked whenever a string conversion is called for, but apparently it is trumped by valueOf(). For example, the code var x = {toString: function() {return "foo"; }, valueOf: function() {return 42; }}; window.console.log ("x="+x); window.console.log ("x="+x.toString()); will print x=42 x=foo This strikes me as backwards .. if x were a complex number, for example, I would want valueOf() to give me its magnitude (so that zero would become special), but whenever I wanted to convert to a string I would want something like "a+bi". And I wouldn't want to have to call toString() explicitly in contexts that implied a string. Is this just the way it is?

  • What's the closest equivalent of Little Snitch (Mac program) on Windows?

    - by Charles Scowcroft
    I'm using Windows 7 and would like to have a feature like Little Snitch on the Mac that alerts you whenever a program on your computer makes an outgoing connection. Description of Little Snitch from its website: Little Snitch informs you whenever a program attempts to establish an outgoing Internet connection. You can then choose to allow or deny this connection, or define a rule how to handle similar, future connection attempts. This reliably prevents private data from being sent out without your knowledge. Little Snitch runs inconspicuously in the background and it can also detect network related activity of viruses, trojans and other malware. Little Snitch provides flexible configuration options, allowing you to grant specific permissions to your trusted applications or to prevent others from establishing particular Internet connections at all. So you will only be warned in those cases that really need your attention. Is there a program like Little Snitch for Windows?

  • get_or_create generic relations in Django & python debugging in general

    - by rabidpebble
    I ran the code to create the generically related objects from this demo: http://www.djangoproject.com/documentation/models/generic_relations/ Everything is good intially: >>> bacon.tags.create(tag="fatty") <TaggedItem: fatty> >>> tag, newtag = bacon.tags.get_or_create(tag="fatty") >>> tag <TaggedItem: fatty> >>> newtag False But then the use case that I'm interested in for my app: >>> tag, newtag = bacon.tags.get_or_create(tag="wholesome") Traceback (most recent call last): File "<console>", line 1, in <module> File "/usr/local/lib/python2.6/dist-packages/django/db/models/manager.py", line 123, in get_or_create return self.get_query_set().get_or_create(**kwargs) File "/usr/local/lib/python2.6/dist-packages/django/db/models/query.py", line 343, in get_or_create raise e IntegrityError: app_taggeditem.content_type_id may not be NULL I tried a bunch of random things after looking at other code: >>> tag, newtag = bacon.tags.get_or_create(tag="wholesome", content_type=TaggedItem) ValueError: Cannot assign "<class 'generics.app.models.TaggedItem'>": "TaggedItem.content_type" must be a "ContentType" instance. or: >>> tag, newtag = bacon.tags.get_or_create(tag="wholesome", content_type=TaggedItem.content_type) InterfaceError: Error binding parameter 3 - probably unsupported type. etc. I'm sure somebody can give me the correct syntax, but the real problem here is that I have no idea what is going on. I have developed in strongly typed languages for over ten years (x86 assembly, C++ and C#) but am new to Python. I find it really difficult to follow what is going on in Python when things like this break. In the languages I mentioned previously it's fairly straightforward to figure things like this out -- check the method signature and check your parameters. Looking at the Django documentation for half an hour left me just as lost. Looking at the source for get_or_create(self, **kwargs) didn't help either since there is no method signature and the code appears very generic. A next step would be to debug the method and try to figure out what is happening, but this seems a bit extreme... I seem to be missing some fundamental operating principle here... what is it? How do I resolve issues like this on my own in the future?

  • Custom array class with assotiated objects

    - by FancyDancy
    I have a simple structure, it's just an array of model's objects. For example, it's a users with books. @books = Book.find(:all, :include = :users) I need to check, does user have a book? I have written a helper method: def has_book?(user_id) @books.select{|b| b.user_id == user_id}.any? end Then, i need to get only books from selected library def in_library(n) @books.select{|b| b.library == n} end I have tried to make custom Array class: class BooksList < Array def initialize(books) self << books end # its my custom methods def has_book?(user_id) self.select{|b| b.user_id == user_id}.any? end def in_library(n) self.select{|b| b.library == n} end end It works, but i have only one problem. I can't access Book's assotiated object (user). So i can't write: @books = BookList.new(Book.find(:all, :include => :users)) @books.first.user.id # it says undefined method `user' for #<Array:0x104b43e08>

  • PHP: Type hints for fields with Eclipse PDT

    - by Silvio Donnini
    Using Eclipse + PDT, I know that you can specify the return type of a method or the type of a variable within a method via type hints. How about class fields? Can I declare the type of a field in order to enable autocompletion for that variable? I tried something on the lines of: class MyClass { protected $Field; /* @var $Field MyType */ ... but it doesn't work. Is there a way to achieve autocompletion of class fields with Eclipse and PDT? thanks, Silvio

  • C# - Angle between two 2d vectors, diff between two methods?

  • How to import a WCF web service using a Java client

    - by JRP
    I have a WCF web service using wsHttpBinding that I am consuming from a Java client. I generated code from the WSDL using wsimport.

MyService s = new MyService(); IMyService i = s.getWSHttpBindingIMyService(); returnedValue = i.getSomething(2); // method call Can a java client communicate with a WCF webservice that is using wsHttpBinding? I have read that I might need to use WSIT (Metro) but am confused on how to proceed with that. Any help will be appreciated.

  • Exception design: Custom exceptions reading data from file?

    - by User
    I have a method that reads data from a comma separated text file and constructs a list of entity objects, let's say customers. So it reads for example, Name Age Weight Then I take these data objects and pass them to a business layer that saves them to a database. Now the data in this file might be invalid, so I'm trying to figure out the best error handling design. For example, the text file might have character data in the Age field. Now my question is, should I throw an exception such as InvalidAgeException from the method reading the file data? And suppose there is length restriction on the Name field, so if the length is greater than max characters do I throw a NameTooLongException or just an InvalidNameException, or do I just accept it and wait until the business layer gets a hold of it and throw exceptions from there? (If you can point me to a good resource that would be good too)

  • Problem updating a database field from my controller

    - by ben
    I have an update method in my users controller that I call from a HTTPService in Flex 4. The update method is as follows: def updateName @user = User.find_by_email(params[:email]) @user.name = params[:nameNew] render :nothing => true end This is console output: Processing UsersController#updateName (for 127.0.0.1 at 2010-05-24 14:12:49) [POST] Parameters: {"action"="updateName", "nameNew"="ben", "controller"="users", "email"="[email protected]"} User Load (0.6ms) SELECT * FROM "users" WHERE ("users"."email" = '[email protected]') LIMIT 1 Completed in 20ms (View: 1, DB: 1) | 200 OK [http://localhost/users/updateName] But when I check my database, the name field is never updated.

  • How to View Android Native Code Profiling?

    - by David R.
    I started my emulator with ./emulator -trace profile -avd emulator_15. I then tracked down the trace files to ~/.android/avd/rodgers_emulator_15.avd/traces/profile, where there are six files: qtrace.bb, qtrace.exc, qtrace.insn, qtrace.method, qtrace.pid, qtrace.static. I can't figure out what to do with these files. I've tried both dmtracedump and traceview on all of the files, but none seem to generate any output I can do anything with. How can I view the proportion of time taken by native method calls on Android?

  • C# int to byte[]

    - by Petoj
    If I need to convert an int to byte[] I could use Bitconvert.GetBytes(). But if I should follow this: An XDR signed integer is a 32-bit datum that encodes an integer in the range [-2147483648,2147483647]. The integer is represented in two's complement notation. The most and least significant bytes are 0 and 3, respectively. Integers are declared as follows: Taken from RFC1014 3.2. What method should I use then if there is no method to do this? How would it look like if you write your own? I don't understand the text 100% so I can't implement it on my own.

  • how do arguments work with dojo.connect?

    - by sprugman
    I've read the docs, but I must be missing something. I've got a grid, I want to connect to the event that fires when the column headers are clicked for sorting, thus: dojo.addOnLoad(function(){ var grid = dijit.byId("grid"); dojo.connect(grid, "setSortInfo", 'afterSort'); }); function afterSort() { console.info('after sort'); } That works fine as far as it goes. I know the setSortInfo method has an argument which is the column number. How do I get that value? I've tried putting a parameter in the sig for afterSort to no avail. The docs say "the method receives the same arguments as the event", but where are they???

  • @OneToMany property null in Entity after (second) merge

  • FOX toolkit, file concatentation

    I'm using the FOX Toolkit and C++ to develop a GUI. I'm Having an issue with the FXFile::concat(...) command. The method looks like: FXFile::concat(const FXString & srcfile1, const FXString & srcfile2, const FXString & dstfile, FXbool overwrite = false And when I call it with the srcfile1 and dstfile being the same thing (because I need to simply add to srcfile1), the method does not work. dstfile is empty. Anyone have experience with FOX and this concatentation problem? I'm open to other suggestions as well, including boost.

    I am new to IIS. Is there a way during the setup of IIS to have a variable of some sort set that I can use to tell my site that this is the development copy? I am using PHP via IIS 7.5 and would like to have a file with a few lines that define which databases etc is used by my application. Is this the purpose of web.config? I would love there to be a place in the setup of the website where I can set a few variables that are accessibly by my application. That way, when I migrate files to live, I don't need to worry about access details to databases etc.
