Is the .net 32-bit max byte array size < 2gb?

阅读更多关于 Is the .net 32-bit max byte array size < 2gb?

问题 I have been looking at some SO questions related to the max size of an array of bytes (here and here) and have been playing with some arrays and getting some results I don't quite understand. My code is as follows: byte[] myByteArr; byte[] myByteArr2 = new byte[671084476]; for (int i = 1; i < 2; i++) { myByteArr = new byte[671084476]; } This will compile and upon execution it will throw a 'System.OutOfMemoryException' on the initialization of myByteArr . If I change the 2 in the for loop to a

How wide is the master page of a Master-Detail Page in Xamarin.Forms?

阅读更多关于 How wide is the master page of a Master-Detail Page in Xamarin.Forms?

问题 Depending on the screen size (and device idiom?) the width of the master page varies: On phones it is about 80 % of the screen width, while on tablets it seems to be a constant dimension like 320 dp. Does anybody know a general formula for this value? I'd like to use it for laying out some elements during construction time, when the Width property isn't set, yet. Edit: I know how to get the current screen size. But how does the width of the presented master page of Xamarin.Form's master

问题 i want to pickle a large (1810392*255) numpy array. However when pickling i get an error: [...]error: 'i' format requires -2147483648 <= number <= 2147483647 Code: import numpy import pickle l=numpy.zeros((1810392,255)) f=open('file.pkl','wb') pickle.dump(l,f,2) Is there a size limit? Is there a workaround? If not necessary I do not want to use hdf5 or something not build into python. I also tried numpy.savez and numpy.savez_compressed . Code: import numpy l=numpy.zeros((1810392,255)) numpy

Get size of mouse cursor in javascript

阅读更多关于 Get size of mouse cursor in javascript

问题 I need to determine the width and height of the current mouse cursor used on our webpage. I need to show a div right under the cursor, and possibly to the right of it. So I need to determine the offsets of my div from the exact pointer location, so the cursor do not cover up the div. The mechanism will be used in intranet system, so it can be firefox-only solution. Unfortunatelly some people here use weird cursors, anyway, big ones, so I cannot just hardcode eg, 16px right, 16px top offsets.

Relative font sizes in QT or the most portable way to define them

阅读更多关于 Relative font sizes in QT or the most portable way to define them

问题 Coming from a Web Development background I am now into QT Applications development. Working with QFonts I have seen that I have only two options apparently, to define fonts sizes in QT; either by pixel size, or point size. When making web layouts I am used to define all my fonts in a relative way... using em units which refer to the inherited font size, where 1em equals the font-size of the container element, 0.5em 50% the font-size, 1.5em 50% bigger, and so on. I am worried about portability

Why does AbstractCollection not implement size()?

阅读更多关于 Why does AbstractCollection not implement size()?

问题 When sub-classing AbstractCollection , I must still implement size() , even though (I believe) there is a reasonable correct (though non-performant) default implementation: public int size() { int count = 0; for (Iterator<E> i = iterator(); i.hasNext();) { i.next(); count++ } return count; } Why did the designers not include a default implementation of size() ? Were they trying to force developers to consciously think about this method, hopefully causing the developer to offer an

.NET DateTime Does Not Have a Predefined Size

阅读更多关于 .NET DateTime Does Not Have a Predefined Size

问题 Since DateTime is a struct with members that appear to break down into simple mathematical values, I'm not sure why using sizeof() on it produces the message in the question title. 回答1: Because the CLR can only determine the size at runtime... one of the reasons for this is "padding" (platform dependent)... For all other types, including structs, the sizeof operator can be used only in unsafe code blocks. Although you can use the Marshal.SizeOf method, the value returned by this method is not
