Visual Basic Random String Generator

Introduction: This tutorial is on how to create a simple random string generation tool in Visual Basic. Steps of Creation: Step 1: First, we will need the Import of System.Random so we can generate a random integer. Step 2: Now, we are going to add five buttons to our project, one numericupdown and one textbox. Keep all the names the same as default as we only need to use "textbox1" in the code. The buttons will: - Generate the string - Add the alphabet to our possible characters - Add the capitalized alphabet to our possible characters - Add numeric values to our possible characters - Add punctuation to our possible characters Step 3: Let's make the adding functions first as we will be using the possible characters for the generate event. These are all simple and just add the string input in to the end of the textbox1.text: Step 4: Now, let's use that textbox1.text to generate a random string. Double click on the generate button and enter this code: First we create a chars array which is each character in our textbox1.text so we can select single characters later on. Next we get the total of chars wanted in the random string but getting the numericupdown value. After that we create cur to hold the current index of our generated string while generating Then we create the string which is being used to hold the current generated string Finally we create our random object as r. Then we simple get a new random number with the maximum number being the amount of possible chars and add the chosen char (the index of our random integer in our chars array) to the end of our endstr returning string. After that we simply reset the randomly generated integer to nothing and plus one on to cur. Then we simply msgbox the end generated string, done! Project Complete!
