  • Does webkit-scrollbar work with webkit-transition?

    - by Trev
    I want a custom webkit-scrollbar to animate a different background color for the hover state. The code below changes the color on hover but doesn't animate anything. It works on a div so I suspect webkit-scrollbar doesn't play nice with transitions. ::-webkit-scrollbar-thumb { background-color: #a8a8a8; -webkit-transition: background-color 1s linear; } ::-webkit-scrollbar-thumb:hover { background-color: #f6f6f6; }

  • CCSprite following a sequence of CGPoints

    - by pgb
    I'm developing a line drawing game, similar to Flight Control, Harbor Master, and others in the appstore, using Cocos2D. For this game, I need a CCSprite to follow a line that the user has drawn. I'm storing a sequence of CGPoint structs in an NSArray, based on the points I get in the touchesBegin and touchesMoved messages. I now have the problem of how to make my sprite follow them. I have a tick method, that is called at the framerate speed. In that tick method, based on the speed and current position of the sprite, I need to calculate its next position. Is there any standard way to achieve this? My current approach is calculate the line between the last "reference point" and the next one, and calculate the next point in that line. The problem I have is when the sprite "turns" (moves from one segment of the line to another). Any hint will be greatly appreciated.

  • How to Connect Crystal Reports to MySQL directly by C# code without DSN or a DataSet

    - by Yanko Hernández Alvarez
    How can I connect a Crystal Report (VS 2008 basic) to a MySQL DB without using a DSN or a preload DataSet using C#? I need install the program on several places, so I must change the connection parameters. I don't want to create a DSN on every place, nor do I want to preload a DataSet and pass it to the report engine. I use nhibernate to access the database, so to create and fill the additional DS would take twice the work and additional maintenance later. I think the best option would be to let the crystal reports engine to connect to MySQL server by itself using ODBC. I managed to create the connection in the report designer (VS2008) using the Database Expert, creating an ODBC(RDO) connection and entering this connection string "DRIVER={MySQL ODBC 5.1 Driver};SERVER=myserver.mydomain" and in the "Next" page filling the "User ID", "Password" and "Database" parameters. I didn't fill the "Server" parameter. It worked. As a matter of fact, if you use the former connection string, it doesn't matter what you put on the "Server" parameter, it seems the parameter is unused. On the other hand, if you use "DRIVER={MySQL ODBC 5.1 Driver}" as a connection string and later fill the "Server" parameter with the FQDN of the server, the connection doesn't work. How can I do that by code? All the examples I've seen till now, use a DSN or the DataSet method. I saw the same question posted but for PostgreSQL and tried to adapt it to mysql, but so far, no success. The first method: Rp.Load(); Rp.DataSourceConnections[0].SetConnection("DRIVER={MySQL ODBC 5.1 Driver};SERVER=myserver.mydomain", "database", "user", "pass"); Rp.ExportToDisk(ExportFormatType.PortableDocFormat, "report.pdf"); raise an CrystalDecisions.CrystalReports.Engine.LogOnException during ExportToDisk Message="Logon failed.\nDetails: IM002:[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified.\rError in File temporal file path.rpt:\nUnable to connect: incorrect log on parameters. the InnerException is an System.Runtime.InteropServices.COMException with the same message and no InnerException The "no default driver specified" makes me wonder if the server parameter is unused here too (see above). In that case: How can I specify the connection string? I haven't tried the second method because it doesn't apply. Does anybody know the solution?

  • Android Service onBind -> onStart

    - by Gernot
    Hello, I have a comprehension question about Android Services. I have a Service that performs background http operations and a Activity that should display the current state of these http operations. So I implementet the Binder interface and so on. I can call the bindService method and onServiceConnected of my ServiceConnnection is getting called. But as far as I know, onBind doesn't calls onStartCommand() and so onStart() of the Service is never called. So how can I call the onStart() method of the service class and start my operations. Or how is the best way to start my operations in the service, when I also want a binding between the Activity and the Service.

  • UIPickerView selectedRowInComponent: returns stale data after code adjusts it

    - by Eric Lloyd
    I have a UIPickerView with multiple components. Some values are grayed out, and my pickerView:didSelectRow:inComponent honors this by shifting the picker component in question to the nearest valid value, much as UIDatePicker moves from "30" to "28" when you select "February". Then it calls a delegate method to announce the adjusted value. When my adjuster method calls my UIPickerView's selectRow:inComponent:animated:YES, the value on screen is correct, but the values from selectedRowInComponent: are stale (from before the adjustment for gray values). However, if I call selectRow:inComponent:animated:NO, the returned values are correct, but the lack of animation is jarring. I've tried wrapping the adjustment in a beginAnimations:/commitAnimations block and catching the values in UIView's +animationDidStopSelector, but I still get stale values. Has anyone run into this before?

  • java.lang.NoSuchMethodError: main when starting HelloWorld with Eclipse Scala plugin

    - by Matt Sheppard
    I've just been playing with Scala, and installed the Eclipse plugin as described at http://www.scala-lang.org/node/94, but after entering the "Hello World" test example and setting up the run configuration as described, I get the following error Exception in thread "main" java.lang.NoSuchMethodError: main For reference the code is package hello object HelloWorld extends Application { println("Hello World!") } I've tinkered a bit with the obvious solutions (adding a main method, adding a singleton object with a main method) but I'm clearly doing something wrong. Can anyone get their test example to work, or point out what I am doing wrong?

  • Is it okay to programmatically create UITouch and UIEvent objects to emulate touch events?

    - by mystify
    I want to simulate some touches on my UI, without using private API. So one simple way to do it is to simply call those -touchesBegan:withEvent:, -touchesMoved:withEvent:, -touchesEnded:WithEvent: and -touchesCancelled:withEvent: methods inside my custom controls. For that, I would have to create UITouch and UIEvent dummy objects with appropriate data inside. Is this fine with them? Or would they reject my app?

    - by Rafael Soto
    Hi Folks, I have an application with client server architecture. The client use Java Web Start with Java Swing / AWT and the sert uses HTTP server / Servlet with Tomcat. The communication is made from the serialization of objects, create a ObjectOutput serializes a byte array and send to the server respectively called the ObjectInputStream and deserializes. The application follows communicating correctly to a certain time of concurrency where starting to show error "SocketException read timeout". The erro happens when the server invoke the method ObjectInputStream.getObject() in my servlet doPost method. The tomcat will come slow and the errors start to decrease server response time until the crash time where i must restart the server and after everything works. Someone went through this problem ?

  • prevent the designer from calling a getter (VS 2008, WinForms)

    - by LLEA
    hi, I have a simple UserControl containing a ComboBox which is empty at first. The setter for that CB adds items to it and the getter returns the selected item. When adding this UC to a Form, the designer automatically calls the getter for the CB which is empty. The method to fill up the CB with items is called later. I can think of one or two ways to bypass this problem by "messing around" in the code. But before I start that I'd like to ask you if there is a way to stop the designer from calling the getter method. Maybe with a attribute similar to Browsable or Bindable? thx

  • Diff between $.ajaxSetup and $.ajax in jquery

    - by Deeptechtons
    title is a bit misleading but i would like to know internally (what happens during ajax request) when i execute Code 1 and Code 2 in turns Code 1 $.ajax({url:"1.aspx/HelloWorld",type:"GET",dataType:"json",contentType:"application/json"}); Code 2 $.ajaxSetup({ contentType: "application/json", dataType: "json" }); $.get("1.aspx/HelloWorld","",$.noop,"json"); i ask this because the method HelloWorld in page 1.aspx is executed correctly when run Code 1. But the seconds one refuses to invoke the pageMethod. I have set the ContentType and data as expected but the second request in Code 2 refuses to invoke the method does anyone have a reason for this ?

  • Account verification Yelp style, how is it more "secure" than traditional verification?

    - by Chad
    For business owners to "take control" of their business page on Yelp, they register for it. The Yelp system performs a telephone call-back. From watching to the video here, it sounds like a telephone version of what we all typically do - e-mail check. For e-mail check, it basically goes like this: User registers verify e-mail sent they click link inside verify e-mail site verifies Here's Yelp's: User registers verify screen shown with code Yelp calls user user enters code site verifies It's essentially the same thing, via phone. Is there any reason you can see why this method is better than the e-mail method?

  • android.app.Application subclass, onTerminate is not being called

    - by synic
    From the documentation for android.app.Application: "Base class for those who need to maintain global application state" I am using my own subclass to maintain an object that I'm using to query a server. Also from the documentation: "onTerminate() Called when the application is stopping." However, onTerminate() in my class is never called. I press the back button while viewing my main activity, and everything seems to shut down. My main Activity's onDestroy() method is called and isFinishing() returns true, but my android.app.Application's onTerminate() method is never called. Why is this? What am I missing? Is there something that is keeping it open?
