  • Developing GWT without a net connection?

    - by user246114
    Hi, When I'm developing my gwt project without a network connection, is there a way to detect this? For example, I have a widget that has an Image in it, and the widget does not display until the Image url request times out (takes a long time, like 2 minutes?). Also, whenever I refresh the page in hosted mode, it doesn't finish loading for about a minute, when no network connection - seems like gwt is trying to contact some external website and blocking on that until it times out too - making things really slow - any way to stop that too? Thanks

  • In asp classic: How can I make sure that a variable can be cast as an int?

    - by Tchalvak
    The following function was suggested to me: ' Defines a forced casting function, which "casts" anything that it can't detect as a number to zero. Function MakeInteger(val) If IsNumeric(val) Then MakeInteger = CInt(val) Else MakeInteger = 0 End If End Function Unfortunately there appear to be some things that return true for IsNumeric() but still can't be cast as an int. Is there any better check to use?

  • When I debug my application I get frequently Launch error: Failed to connect to remote VM

    - by Pentium10
    When I debug my application I get frequently Launch error: Failed to connect to remote VM even If I try again it doesn't help, I need to restart Eclipse. Edit Not sure yet fully if the symptoms have to do with the fact that I get this error only when I launch Debug without a code modification. Whenever I do a modification to the source code and hit Debug it goes through, but if I don't it doesn't.

    - by Mark Lubin
    For the CS majors out there what were the hardest CS classes or concepts that you learned in your undergraduate schooling? Did you find once you learned the basics,(data structs, OOP fundamentals, discrete math, pointers, recursion, etc) the rest followed naturally or did you hit a wall at any point in your higher classes like OS'es and Compilers? Thanks for the input!

  • Odd behaviour with scala method syntax

    - by Ceilingfish
    Hi chaps, I hit a bit of a quirk of scala's syntax I don't really understand object Board { def getObjectAt(x:Int, y:Int):Placeable = return locations(x)(y) } works fine. But object Board { def getObjectAt(x:Int, y:Int):Placeable { return locations(x)(y) } } returns the error Board.scala:8: error: illegal start of declaration return locations(x)(y) I found some stuff that says the second form convinces the scala compiler you're trying to specify an expansion to the return type Placeable. Is there a way I can fix this, or should I just avoid specifying a return type here?

  • Chain of Responsibility Pattern: is it a good practice to have interdependent handlers?

    - by wei
    I have this scenario: I have a chain of query handlers, the first is to query the cache, if the cache can't answer it or the answer is stale, then hit a database, if it can't find the answer or the answer is stale again, then query a remote web service. But I am not sure if this is the right way to use this pattern, since the work flow is pretty much fixed, and the cache and database handlers depend on the next step's return result to refresh its records.

  • Map resources when added to the project

    - by Espuz
    I have a .h when I map all the image files names and xib names with #defines. For example, if I have an image called "buttonBackground.png" I map it in my .h as #define BUTTON_BACKGROUND_PNG_FILE @"buttonBackground.png" It's possible to detect when a resource is added to the bundle and create the correspond define with a script?

  • How to use ObjectAnimator to change a the background of a View with a crossfade (or fade out - fade in) animation?

    - by jul
    is there any way to create one animation with ObjectAnimator to change the background of a View with a crossfade animation? Something like ObjectAnimator.ofObject(<myView.background>, <crossfade or fade in -fade out>, <resources_1>, <resources_2>); I know I can do a fade out of one image, set a listener to detect the end of the animation, and fade in the other image. I'd just like to know if there's a more elegant way... Thanks
