If I copy all the stuff in the window, then I have a lot of stuff to delete and to correct. (and is not easy to copy from shell) Resume: I want to take all the things I wrote... Is there an easy way to do this easy task?

• What's the reason I can't create generic array types in Java?

  - by devoured elysium

  What's the reason Java doesn't allow us to do private T[] elements = new T[initialCapacity]; ? I could understand .NET didn't allow us to do that, as in .NET you have value types that at run-time can have different sizes, but in Java all kinds of T will be object references, thus having the same size(correct me if I'm wrong). What is the reason?

  I have a tab bar based application. What is the best way to toggle between 2 different UITableView views? Should I use a wrapper view and add those 2 views to it and depending on which segment was chosen I will show the correct view?

I know the source of contents are from volunteers (Please correct me if I'm wrong here). But what measures they have to ensure that contents are properly written.

  Does WPF support multiple binding expressions in one statement? Something along the lines of the following: <TextBlock Text="{Binding Path=OrderID} shipped on {Binding Path=OrderDate}"/> I'm guessing that it does but I think I just don't have the correct syntax.

• #Define Compiler Directive in C#

  - by pm_2

  In C, I could declare a compiler directive as follows: #define MY_NUMBER 10 However, in C#, I only appear to be able to do this: #define MY_NUMBER Which is obviously useless in this case. Is this correct, or am I doing something wrong? If not, can anyone suggest a way of doing this, either at namespace or solution level? I thought of maybe creating a static class, but that seems to be overkill for one value.

• Find the exact height and width of the viewport in a cross-browser way (no Prototype/jQuery)

  - by lyoshenka

  I'm trying to find the exact height and width of a browser's viewport, but I suspect that either Mozilla or IE is giving me the wrong number. Here's my method for height: var viewportHeight = window.innerHeight || document.documentElement.clientHeight || document.body.clientHeight; I haven't started on width yet but I'm guessing it's going to be something similar. Is there a more correct way of getting this information? Ideally, I'd like the solution to work with Safari/Chrome/other browsers as well.
