  • Calling C# code from Java?

    - by Keith G
    Does anyone have a good solution for integrating some C# code into a java application? The code is small, so I could re-write in java, but I would rather reuse the code if possible. Don't repeat yourself, etc. Also, I know I can expose the C# as a web service or whatever, but it has some security/encryption stuff in there, so I would rather keep it tightly integrated if possible. Edit: It's going to be on a server-based app, so "downloading" another runtime is irrelevant.

  • Why is the compiler not complaining about an additional ',' in Array or Object Initializers?

    - by Danvil
    Using simple type like class A { public int X, Y; } with object intializers, one can write var a = new A { X=0, Y=0 }; But the following is also accepted by the compiler: var a = new A { X=0, Y=0, }; // notice the additional ',' Same for int[] v = new int[] { 1, 2, }; This looks a bit strange ... Did they forgot to reject the additional ',' in the compiler or is there a deeper meaning behind this?

  • Can I optimize this at all?

    - by Moshe
    I'm working on an iOS app and I'm using the following code for one of my tables to return the number of rows in a particular section: return [[kSettings arrayForKey:@"views"] count]; Is there any other way to write that line of code so that it is more memory efficient? EDIT: kSettings = NSUserDefaults standardUserDefaults. Is there any way to rewrite my line of code so that whatever memory it occupies is released sooner than it is released now?

  • Create automatically only getters in Eclipse

    - by lerad
    In Eclipse is it possible to create automatically Getters and Setters for a field. But I have a lot of private fields for which only getters should exist. Is somewhere in Eclipse a "create Getters" Function which does not create setters too? Well, it is not so much work to write getters, but doing it automatically would be nice :) Thank you, lerad

  • Performance Cost of a Memcopy in C/C++

    - by Cenoc
    So whenever I write code I always think about the performance implications. I've often wondered, what is the "cost" of using a memcopy relative to other functions in terms of performance? For example, I may be writing a sequence of numbers to a static buffer and concentrate on a frame within the buffer, in order to keep the frame once I get to the end of the buffer, I might memcopy all of it to the beginning OR I can implement an algorithm to amortize the computation.
