I am looking for some solution of the random user image.I created some image and calling it from database if user has no image.But i dont like it, it is quite ugly.Is it exists some random image generator, like here in stackoverflow the the user has no photo.
View 2 RepliesI 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
[code]....
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'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
Public Class CustomStrings
''' <summary>'
''' Generates a Random String'
''' </summary>'
''' <param name="n">number of characters the method should generate</param>'
''' <param name="UseSpecial">should the method include special characters? IE: # ,$, !, etc.</param>'
''' <param name="SpecialOnly">should the method include only the special characters and excludes alpha numeric</param>'
''' <returns>a random string n characters long</returns>'
Public Function GenerateRandom(ByVal n As Integer, Optional ByVal UseSpecial As Boolean = True, Optional ByVal SpecialOnly As Boolean = False) As String.............
I 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)
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).

Is this correct?
I am working with two different web sites in asp.net. In the first project i upload some images to a specific folder under the project root and save just the filename in the database, now i am trying to display this images at some page of the second project I know the filename from the database and the image folder as absolute pat but I have not been able to display the image, even thought when looking in firebug the image src is correct src="D:/MyFolder/image.jpg" the image does not display, probably because it is not pointing in the right directory. I have also tried using Server.MapPath and then my D location but still no success.

I have an existing application that was written in .NET 3.5. The piece of code in question is using the FileUpload control and its SaveAs method. Its worked perfectly for the past six months, but I've recently upgraded the project to .NET 4.0 and I'm now receiving an "Access to path (...) is denied" every time the method is called. It works fine locally in dev mode but fails on my prod server. I've upgraded the website to run under .NET 4.0 and I've made sure the account (Network Service) it runs under in the app pool has full control. Other than upgrading to .NET 4.0, nothing has changed for the project.
