• Generating an Excel file in ASP.NET

  - by Dan Coates

  I am about to add a section to an ASP.NET app (VB.NET codebehind) that will allow a user to get data returned to them as an Excel file, which I will generate based on database data. While there are several ways of doing this, each has its own drawbacks. How would you return the data? I'm looking for something that's as clean and straightforward as possible.

• Python: Is there a way to reflectivly list all attributes of a class

  - by hhafez

  Given a class such as def MyClass text = "hello" number = 123 Is there a way in python to inspect MyClass an determine that it has the two attributes text and number. I can not use something like inspect.getSource(object) because the class I am to get it's attributes for are generate using SWIG (so they are hidden in .so :) ). So I am really looking for something equivalant to Java's [Class.getDeclardFields][1] Any help would be appreciated, otherwise I'll have to solve this problem with SWIG + JAVA instead of SWIG + Python.

  - by vbNewbie

  I would like to generate a combination of words. For example if I had the following list: {cat, dog, horse, ape, hen, mouse} then the result would be n(n-1)/2 cat dog horse ape hen mouse (cat dog) (dog horse) (horse ape) (ape hen) (hen mouse) (cat dog horse) (dog horse ape) (horse ape hen) etc Hope this makes sense...everything I found involves permutations The list I have would be a 500 long

• How does a cryptographically secure random number generator work?

  - by Byron Whitlock

  I understand how standard random number generators work. But when working with crytpography, the random numbers really have to be random. I know there are instruments that read cosmic white noise to help generate secure hashes, but your standard PC doesn't have this. How does a cryptographically secure random number generator get its values with no repeatable patterns?

• k-combinations of a set of integers in ascending size order

  - by Adamski

  Programming challenge: Given a set of integers [1, 2, 3, 4, 5] I would like to generate all possible k-combinations in ascending size order in Java; e.g. [1], [2], [3], [4], [5], [1, 2], [1, 3] ... [1, 2, 3, 4, 5] It is fairly easy to produce a recursive solution that generates all combinations and then sort them afterwards but I imagine there's a more efficient way that removes the need for the additional sort.

• Strings Generation

  - by sikas

  Hi,I would like to know how can I create various string from some given characters eg: given characters: a, b I would like to generate the following strings: aa ab ba bb What I have thought of is having (for 2 inputs only) two for-loops one inside another, and then loop each to the number of inputs which in this case is 2 and the output strings will be 2*2 = 4 strings and as the number increases the number of output strings will increase by multiplying n*n (n-times)

• Get a random subset from a set in F#

  - by Cay

  I am trying to think of an elegant way of getting a random subset from a set in F# Any thoughts on this? Perhaps this would work: say we have a set of 2x elements and we need to pick a subset of y elements. Then if we could generate an x sized bit random number that contains exactly y 2n powers we effectively have a random mask with y holes in it. We could keep generating new random numbers until we get the first one satisfying this constraint but is there a better way?

• Find out why Xcode has decided to link to a particular library

  - by andygeers

  I'm using the Unity 3D engine to build an iPhone app, and when I go to generate my Xcode project for compilation, it includes a few fairly large libraries: Mono.Security.dll.s, System.dll.s, System.Core.dll.s, etc. I don't know if this question is really an Xcode question or a Unity question, but I'm trying to figure out why each of those libraries is being linked - which functions / classes are being referenced - ideally so that I can rewrite my code to remove as many of the dependencies as possible. Does anybody know a way to find this information out?
