This example shows how to generate random colors in VB.

#VB NET 2010 GENERATE RANDOM STRING CODE#

This code is in C# but should be fairly easy to convert to VB.NET using a code converter.VB Helper: HowTo: Generate random colors in VB. String b = RandomStringGenerator.Generate(10) // Generate 10 character random string To use it: string a = RandomStringGenerator.Generate() // Generate 8 character random string Private static char GetRandomCharacter(string s, Random rand) Return (m_UseSpecialChars) ? m_SpecialChars : m_LowercaseChars Private static string GetRandomString(Random rand) SB.Append(GetRandomCharacter(GetRandomString(rand), rand)) Now add random characters up to the end of the string SB.Append(GetRandomCharacter(m_SpecialChars, rand)) SB.Append(GetRandomCharacter(m_NumericChars, rand)) SB.Append(GetRandomCharacter(m_UppercaseChars, rand)) SB.Append(GetRandomCharacter(m_LowercaseChars, rand)) Ensure that we add all of the required groups first If (length < 4) throw new ArgumentException('String length must be at least 4 characters') The generated string must be at least 4 characters so that we can add a single character from each group. numerals, and special characters (!, #, $, Р’Р€, etc) Generated strings must contain at least 3 of the following character groups: uppercase letters, lowercase letters In this article, we will understand How to generate РІР‚ВCAPTCHAРІР‚в„ў (Random String) in Visual Basic(VB.NET). Private static string Generate(int length, int seed) Program to generate РІР‚ВCAPTCHAРІР‚в„ў (Random String) in Visual Basic(VB.NET). / Generates a string of the specified length using the specified seed

Return Generate(length, Environment.TickCount) Public static string Generate(int length) Which you then can do various string functions to make it the way you want. Save to your folder(s) If you need to generate a random string of mixed characters, this simple function will do it for you. / Generates a string of the specified length Generate a Random String / Published in: VB.NET. / Generates string of the minimum length Private const string m_SpecialChars = Public Methods Private const string m_NumericChars = '123456890' Private const string m_UppercaseChars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ' Private const string m_LowercaseChars = 'abcdefghijklmnopqrstuvqxyz' Private static bool m_UseSpecialChars = false public static class RandomStringGenerator It's similar to JohnIdol's Typing Monkey, but has a little more flexibility in case you want generated strings to contain uppercase, lowercase, numeric or special characters. Here's a utility class I've got to generate random passwords. String randomStr = myMonkey.TypeAway(size) Then all you've got to do is: TypingMonkey myMonkey = new TypingMonkey() StringBuilder builder = new StringBuilder() Р”В¬h = legalCharacters / The Typing Monkey Generates a random string with the given length. Private const string legalCharacters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890' / If you try hard enough it will eventually type some Shakespeare. / The Typing monkey generates random strings - can't be static 'cause it's a monkey. If you can convert this to VB.NET (which is trivial) I'd say you're good to go (if you can't, use this or any other tool for what's worth): ///
