View 5 RepliesC# - Random Number Generator Returning Zeros?
Sep 20, 2010I have an ASP.NET application that relies on the Random class to generate a pseudo-random string. It uses the following code (this is part of a larger piece of sample code provided by Google for apps SSO):
public static class SamlUtility
{
private static Random random = new Random();
private static char[] charMapping = { 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p' };
public static string CreateId()
{
byte[] bytes = new byte[20]; // 160 bits
[Code]...
This normally works very well, but from time to time it starts generating a string of 'a'. From what I can tell from debugging, Random simply stops returning random numbers and instead fills bytes with the same value over and over. I've patched this by using a GUID instead, but I'm curious what happened in the original code. I'm assuming some form of entropy exhaustion, but I can't find any reference in the docs. Also, each time this has happened, performing iisreset restored the correct behavior.

Sep 27, 2010im hope i can make sense to this post cause i dont have an idea where to begin :-) I have some files upload code so the user can upload files to the server (it can be 1 or 5 or 20 files). the code is working fine, and the files uploading to the folder on the server. The problem is, that after the files uploads i need to display to the user some textboxes to every file (like: number of copies, if its color or b/w, the print size etc). is there some way, after the files is uploaded, to show the user the name of the files and for each file name to display some textboxes (like: to count the number of files and then display the names and few same textboxes for each file),
