Visual Basic 2008, Random sting generator with custom length, how to make it?


Now your length is fixed - you run the loop For i As Int32 = 1000 To 3000 (i.e. 2001 times) and then add 3 symbols in each loop, which gives you 3 x 2001 = 6003 length.

Easiest way would be to define the array of the symbols that are allowed and then combine random number of these:

Dim random As New Random
Dim password As New System.Text.StringBuilder
Dim allowedSymbols as Integer() = {48, 49, ...,
122}    ' Define the list of allowed symbols
Dim length = random.Next(10, 50)    'length of the
string - from 10 to 50 symbols
For i As Int32 = 0 To length
   
password.Append(Chr(allowedSymbols(random.Next(allowedSymbols.Length))))
Next

Visual Basic Text Box Array for random number generator
Try to use a foreach loop for all textboxes as below: Dim RandomNumberAHigh As Integer = 12 Dim RandomNumberALow As Integer = 1 Dim Random As Integer = 0 For Each txt As Control In Me.Controls If TypeOf txt Is TextBox Then txt.Text = Int((RandomNumberAHigh - RandomNumberALow + 1) * Rnd() + RandomNumberALow) End If Next

"Efficient" is pretty subjective. There are many ways to do it: Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click RandomizeTextBoxes(1, 12) End Sub Private Sub RandomizeTextBoxes(ByVal Low As Integer, ByVal High As Integer) Static R As New Random For i As Integer = 1 To 30 Dim matches() As Control = Me.Controls.Find("Rnd" & i, True)

Visual Basic / Visual Studio 2013 Trackbar Movement Direction
Thanks idle. Thank you for creating a definition for this before-unforeseen conundrum. I tried declaring a variable to hold the previous value of the trackbar, but I couldn't quite figure out how to go about it since every time the trackbar is moved the variable is changed. Edit: Figured it out, sorry for being a noob... Private Sub TrackBar1_Scroll(sender As Object, e As EventArgs) Handles Tr

Random Number Generator w/ no Repeats Modification?
You could remove the values from nums for every iteration in getRandom; that way there won't be a duplicate: function getRandom() { var nums = [1,2,3,4,5,6,7,8,9]; var gen_nums = []; function get_rand(array) { var i = Math.floor(Math.random()*array.length); var rand = array[i]; gen_nums.push(rand); // remove from original array nums.splice(i, 1); } for(var i = 0; i
