  • How to convert String to Java.sql.date and Java.sql.time

    - by Mr Morgan
    Hello If I have a method like this: public static String convertDateTimeToString(DateTime dt) { return dt.getDate() + " " + dt.getTime(); } Which takes a Datetime object of my own which contains a Java.sql.date and a Java.sql.time, what is the best way of reversing the process so that I can substring a Java.sql.date and a Java.sql.time from a string? Or if DateTime dt is a JodaTime DateTime object? If this can be done without reference to Java.util.date. Thanks Mr Morgan.

  • Can I use an NSDecimalNumber anywhere that an NSNumber is expected?

    - by Nick Forge
    NSDecimalNumber is a subclass of NSNumber, and from what I can tell, it implements all of the NSNumber methods as expected for an NSNumber instance. Given that, is it ok to give NSDecimalNumbers to any code that is expecting an NSNumber? The only possible issue might be code that checks that an argument is an instance of NSNumber, but since NSNumber is a class-cluster, code like this would have to check that the instance is a subclass of NSNumber, and NSDecimalNumber instances should pass the same tests.

  • Why does 'localhost' in web references cause SocketExceptions?

    - by Sam
    I have two .net web services deployed to the same IIS server using SSL, one that references the other. If I set that web reference to 'localhost', some calls fail with this exception: System.Web.Services.Protocols.SoapException: Server was unable to process request. --- System.Net.WebException: Unable to connect to the remote server --- System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it If I set it to the actual machine name, it works. Why?

  • Flash media server delayed streaming

    - by yn2
    I have a RED5 server I'm using to pass a live streaming between users' cameras. What I need now is a way to create a delayed broadcast of the camera (intended delay) so that "super users" will be able to see it immediately and others will get it 10-15 seconds later. If FMS is better for that, I will be happy to know why and how too. Any help will be appreciated.

    - by Chris S

Inside the generic.xaml file is a simple Grid with 2 rows: Row 1 - A toggle button Row 2 - A StackPanel with a TextBlock, named "Stackpanel1" The ToggleButton has its own nested ControlTemplate which has VisualStates for Checked/Unchecked. Is it possible to reference "Stackpanel1" from inside the ToggleButton's control template somehow? In order to show or hide the stackpanel.

  • get current selected button cell placed inside tableview using cocoa

    - by Swati
    hi i have a NSTableView i have two columns A and B B contains some data A contains custom button the button is added to column A using this: Below code is placed inside awakeFromNib method NSButtonCell *buttonCell = [[[NSButtonCell alloc] init] autorelease]; [buttonCell setBordered:NO]; [buttonCell setImagePosition:NSImageOnly]; [buttonCell setButtonType:NSMomentaryChangeButton]; [buttonCell setImage:[NSImage imageNamed:@"uncheck.png"]]; [buttonCell setSelectable:TRUE]; [buttonCell setTag:100]; [buttonCell setTarget:self]; [buttonCell setAction:@selector(selectButtonsForDeletion:)]; [[myTable tableColumnWithIdentifier:@"EditIdentifier"] setDataCell:buttonCell]; Some code in display cell of nstableview: -(void)tableView:(NSTableView *)tableView willDisplayCell:(id)cell forTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)rowIndex { if(tableView == myTable) { if([[tableColumn identifier] isEqualToString:@"DataIdentifier"]) { } else if([[tableColumn identifier] isEqualToString:@"EditIdentifier"]) { NSButtonCell *zCell = (NSButtonCell *)cell; [zCell setTag:rowIndex]; [zCell setTitle:@"abc"]; [zCell setTarget:self]; [zCell setAction:@selector(selectButtonsForDeletion:)]; } } } now i want that when i click on the button the image of button cell gets changed as well as i want to do some coding. When button gets clicked then by default the tableView's reference gets passed. How can i get the button cell reference i looked here for similar problem: Cocoa: how to nest a button inside a Table View cell? but i am unable to add button inside column of NSTableView. How i change the image: - (void)tableView:(NSTableView *)tableView setObjectValue:(id)object forTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row; { if(tableView == myTable) { if([[tableColumn identifier] isEqualToString:@"EditIdentifier"]) { NSButtonCell *aCell = (NSButtonCell *)[[tableView tableColumnWithIdentifier:@"EditIdentifier"] dataCellForRow:row]; NSInteger index = [[aCell title]intValue]; if([self.selectedIndexesArray count]>0) { if(![self.selectedIndexesArray containsObject:[NSNumber numberWithInt:index]]) { [aCell setImage:[NSImage imageNamed:@"check.png"]]; [self.selectedIndexesArray addObject:[NSNumber numberWithInt:index]]; } else { [aCell setImage:[NSImage imageNamed:@"uncheck.png"]]; [self.selectedIndexesArray removeObjectAtIndex:[selectedIndexesArray indexOfObject:[NSNumber numberWithInt:index]]]; } } else { [aCell setImage:[NSImage imageNamed:@"check.png"]]; [self.selectedIndexesArray addObject:[NSNumber numberWithInt:index]]; } } } } I have debugged the code and found that proper tag and titles are passed but image applies on more than one button cell, this is too very irregular. cant understand how its working!!! Any suggestions what am i doing wrong??

The code has some resource dependencies (layouts, xml & png drawables) that I would like to be able to include and reference within a single package (Jar file). Is this possible, and if so what is the best method to do this?

  • Is it possible to configure a Spring session scoped bean with attributes from the session?

    - by Dave G
    I'm trying to create a service bean that when referenced will be initialized with HttpSession based attributes. Let's say for sake of argument that my webapp would do the following: Establish a session Request login & password When service is requested (it is scope="session" and has init-method="init()") a new instance is created for the session. In the init method, can I reference the HttpSession either through passing it in as a parameter and referencing it by EL? Any ideas on this would be appreciated.

  • Loading Accessory callout view for mkannotationview

    - by Zap
    I have a map annotation view that contains a rightcallout button which loads an accessory view which is a UIViewController class. I am using resuable annotations, but am wondering how I can pass updated information to my UIViewController class. Let's say I have 2 string values which map to 2 UILabels on my view. How can I update those values after the initial accessory view has already been loaded into memory as a resusable view? Any help would be appreciated.

  • How do you test the usability of your user interfaces

    - by Martin
    How do you test the usability of the user interfaces of your applications - be they web or desktop? Do you just throw it all together and then tweak it based on user experience once the application is live? Or do you pass it to a specific usability team for testing prior to release? We are a small software house, but I am interested in the best practices of how to measure usability. Any help appreciated.

  • Difference between WinMain and wWinMain

    - by Sherwood Hu
    The only difference is that Winmain takes char* for lpCmdLine parameter, while wWinMain takes wchar_t*. On Windows XP, if an application entry is WinMain, does Windows convert the command line from Unicode to Ansi and pass to the application? If the command line parameter must be in Unicode (for example, Unicode file name, conversion will cause some characters missing), does that mean that I must use wWinMain as the entry function?

  • Member variable pointers to COM objects

    - by drelihan
    Hi Folks, Is there any problem with keeping member variable pointer refernces to COM objects and reussing the reference through out the class in C++. Is anybody aware of a reason why you would want to call .CreateInstance every time you wanted a to use the COM object i.e. you were getting a fresh instance each time. I cannot see any reason who you would want to do this, Thanks, (No is an acceptable answer!!!)

  • Does @JoinTable has a property of "table" or not?

    - by Kent Chen
    The following is copied from hibernate's document. (http://docs.jboss.org/hibernate/stable/annotations/reference/en/html_single/#d0e2770) @CollectionOfElements @JoinTable( table=@Table(name="BoyFavoriteNumbers"), joinColumns = @JoinColumn(name="BoyId") ) @Column(name="favoriteNumber", nullable=false) However, when I put this in practice, I just found that @JoinTable has no "table" property, instead it has a "name" property to specify the table name. But I need "table" property to specify indexes. What's going on here? I'm almost driven crazy!

  • When does an asio timer go out of scope?

    - by ApplePieIsGood
    What I mean is, let's say you do an async_wait on an asio timer and bind the update to a function that takes a reference to a type T. Let's say you created the T initially on the stack before passing it to async_wait. At the end of that async_wait, it calls async_wait itself, renewing the timer over and over. Does that stack allocated type T stay alive until the first time the timer doesn't renew itself, or after the first invocation of the function will the T go out of scope?

  • Python double underscore mangling

    - by gnr
    I am a bit confused by this behavior (using python 3.2): class Bar: pass class Foo: def __init__(self): self.__cache = None bar = Bar() bar.__cache = None foo = Foo() print(vars(bar)) #returns {'__cache': None} print(vars(foo)) #returns {'_Foo__cache': None} I've read up a bit on how double-underscores cause attribute names to be "mangled", but I would have expected the same name-mangling in both cases above. The meaning of a single- and a double-underscore before an object name in Python Any ideas what's going on here?

  • Hidden WCF endpoints

    - by Matt
    For the sake of arguement, lets say that I've got a basicHttp WCF service. Besides implementing authentication (login/logout methods), what is stopping someone from just cracking open Visual Studio, adding a web reference to my website's service, and then playing playing around with my service? I'm not familiar with a method of stopping someone from doing this. The idea of someone downloading all of my Data/Operation contracts and then start playing around is keeping me up at night, and I like my sleep!

  • IE only jQuery bug

    - by Greg-J
    jsbin for reference: http://jsbin.com/edago3/5/ When viewed in any other browser, the toggler works as you would expect it to. However, in IE (I'm using 8), you can only contract the currently expanded sub menu, and then you get undesired results once it is closed.
