I want to create a random password generator in my ASP.NET C# web application.
I have created that but it is applicable only for the integer format. If I give any characters it shows the debugging error as "my input format is wrong".
But i want to enter both string and integer. For example my textbox field may be

View 2 RepliesI am trying to create a password generator which will do the following:
1) Generate a simpler password, than just completely random as this is what currently the Membership classes do if the above cannot be done then how can we kind of mimic the randomness but use a predefined list of perhaps common words?
2) if we have a Regex expression, is there any way a password can be generated randomly complying with that regex expression? (something extra to think about)
Random rand = new Random((int)DateTime.Now.Ticks);
int numIterations = 0;
numIterations = rand.Next(1, 50);
Response.Write(numIterations.ToString());
Response.Write(' ');
numIterations = rand.Next(1, 50);
Response.Write(numIterations.ToString());
Response.Write(' ');
numIterations = rand.Next(1, 100);
Response.Write(numIterations.ToString());
Response.Write(' ');
numIterations = rand.Next(50, 100);
Response.Write(numIterations.ToString());
[Code]....
This is what i have so far. first 2 number gives 1-50, then 1-100, then last two give 50-100
now i need to make the first 2 numbers give even or odd numbers. how can i do this?
I 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.
i am generate random password and show it in a textbox. when i am set textbox property textmode to password then it doesn't show in textbox but when i set it singleline then password shows in textbox. I am using following code --
textbox1.attributes.add("value",passwordvalue);
for show i am using --
textbox1.text = textbox1.attributes["value"].tostring();
Same happing with when i edit record. password doesn't show in textbox.
I've build a random string generator but I'm having a problem whereby if I call the function multiple times say in a Page_Load method, the function returns the same string twice.here's the code

I have a system where I salt and hash passwords before saving them to the database, using FormsAuthentication in asp.net
What I want to do is, rather than ask the customer for their password each time, I just want 3 random letters from their password. How can I compare this to the hash in the database? Will hashing still work in this case? From what I gather hashing is only designed to be a one way process and shouldn't be decrypted, so is checking 3 random letters for a hash even possible?
know which is the best PDF generator I can use in ASP.NET.
I also need a library which allows me to draw charts.
I need this libraries to be free. tell me which ones do you use.
I am trying to create a Question Bank application for one of our clients. What is the main challenge I am facing is a typical demand from the client. What they want is : Whenever users open this site a set of random numbers(range say 1 to 20) should be generated and questions with the QuestionID(column in a table in Database) according to the numbers would be displayed in the page. I have done it to some extent but, still not satisfied with it.
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
int[] n = new int[10];
int rn;
bool Check = true;
int[] n1 = new int[10];
Random rand = new Random();
n1[0] = rand.Next(1, 21);
for (int i = 1; i < 10; i++)
{
rn = rand.Next(1, 21);
for (int j = 0; j < n1.Length; j++)
{
if (n1[j] == rn)
{
Check = false;
break;
}
else
continue;
}
if (Check == true)
n1[i] = rn;
}
for(int i=0;i<10;i++)
Response.Write(n1[i] + " ");
}
}
Here are some O/Ps : 11 13 14 4 16 0 0 0 0 0 (1st load)
5 9 8 1 0 0 0 0 0 0 (after refreshing the page)
16 10 20 6 8 17 11 7 0 0 (after refreshing again)
I want that, all these digits in each refresh should be unique(which is comming) but all set should 10 digits(this is not happening).

View 3 RepliesWe are using Ultramain(DB: Oracle 10g and Language: Progress) as a MRO application for aircraft health check. Ultramain has more than 3000 users and using this application around the world. Users are forgetting the password frequently and we are getting the mail minimum 10 password reset from the user. I have planned to create a website for reset the password themselves if user valid. Only one button in the website called "RESET". If user click the reset button, it should check the user have already access using the table called "USER". If users have access, it should check the user authentication. If users does have access, the message appears "You do not have an access". If authentication success,update thepassword from the table "RESETPWD" to application table "USER".

USER --- application user table

I'm using a website as a frontend and all users are authenticated with the standard ASP.NET Membership-Provider. Passwords are saved "hashed" within a SQL-Database.Now I want to write a desktop-client with administrative functions. Among other things there should be a method to reset a users password. I can access the database with the saved membership-data, but how can I manually create the password-salt and -hash? Using the System.Web.Membership Namespace seems to be inappropriate so I need to know how to create the salt and hash of the new password manually.

When a user that has their IE set to save passwords hits my "Reset Password" form, the first text box set with TextMode set to "Password" is populated with the users saved password. Understandable, this is not the affect I would like as this is their "old" password. I cannot set the text of a text box with mode set to "Password" (naturally). Does someone know how to suppress or clear this value when IE is saving passwords?
