Mar 14, 2012i have a few questions about generating random numbers:1) is it possible for the programme to generate a random number that it has previously generated (i.e could it produce the same number more than once?)2) can you specify what numbers to generate? e.g only whole numbers up to 1000?

Feb 6, 2011I am working on an application, where I have already normalized the databases. Now I am creating an application in asp.net with vb.net as my code behind fine. These random numbers would be stored in the Id column. So, no way there would be repeating the keys. But my application could generate the key, which would probably get repeated. How would I check the database for, so that random numbers wont get repeated? is there any function? Could you give me the code for the same.

To complicate things a little, each combination needs to be different, ie. randomised but still according to the 'letter,number, letter' formula. There are plenty of examples of randomising strings such as passwords but I cannot understand how to achieve the above.

Jan 17, 2012I have to (for class) make a program that generates a safe passwords for people to use. My teacher wants us to make the passwords vary in length, include numbers, letters and upper case letters. I've been able to write code that prints out a random string but it includes unrecognized characters for most passwords. How would I write the code to create a random string that has parameters? (in this case upper case lower case letters and numbers).

Jun 16, 2009I made a small license generator app with a datetimepicker, a textbox and a button on the form. When I ran the app and clicked the button to generate a license I got - 16DDD-06DDDD-09DDDDD, and each subsequent button click would get me a license with a different generated character (16444-064444-0944444, etc...).
I thought this was unusual as it should be generating a random character not a repeating one, so I stepped through in debug and the characters generated were random (161g2-06T5ip-0957H9k). I thought perhaps that I needed to seed the value with Now().Milliseconds, no luck, that still resulted in repeating characters. So I tried sleeping the thread and that generated the random values I wanted.

View 1 RepliesGenerating Standard Letters For End User To View And Print
Aug 8, 2009Im developing an app at the moment where standard letters need to be generated to be sent out to customers. With the customers details then filled in as you would expect... name, title, address, etc. This is an app ontop of a SQL db. The way i envisioned this working was to send the customer details to another form that had a crystal report in, and send the info via a SQL query, just as you might get a grid view to open with a query.
Thing is im struggling with it, getting the query to work especially. Ive built the report and put the relevant field place holders in there, but i cant get it to open with just the one customers info in there, it gets every customer and builds a report several thousand pages long! This is because of the "command" thats on the report that i stuck in there on a temp basis while i designed the thing.
However i want the the report to open via a button on another form, and then fill the report with the customers details (using the customer ID number on the form the button was clicked) Since im struggling with this so much, im actually wondering if im going the best way about this? Are there better ways of generating a standard letter that the end user can then view, check it, and hit print?
Generating Salt - LENGTH Of Salt Be Random - Fixed Or A Random Number Within A (min/max) Range ?
Nov 26, 2011VS2010 (SP1) / .NET 4 on Windows XP. The question is simple, the answer; not so much. When generating a salt, should the LENGTH of the salt be random, fixed or a random number within a (min/max) range? I am using RNGCryptoServiceProvider to generate the salt, just unsure of the length of the salt.
