Many of you will know that I do like coding and out of all the languages I like Microsoft Classic ASP. The reason is simple, I started coding in the 1980s with BBC Basic on my Acorn Electron then GW and Visual Basic on PCs and then a natural progression to Classic ASP when the web came along. It's such a simple language to master and easy to follow. You can take basic HTML files and add dynamic content using the simple
<% %> directives.
From time to time you need functions which extend the language and the other day working on mamadada.com I needed to fill an array with 5 unique numbers from a specific range. Here is the result with example code following on.
Function RandomUnique(min, max, n)
' Returns a string of comma delimited numbers of unique values within a specific range
' min & max are the upper and lower
' n is the number of values to return in the string
' x = RandomUnique(1, 59, 6)
' arrLotteryNumbers = Split( x, "," )
If min > max Then
RandomUnique = "min > max"
If n > (max - min) + 1 Then
RandomUnique = "Too many numbers requested in the range."
result = ","
cnt1 = n
Do Until cnt1 = 0
RndNumber = Int((max - min + 1) * rnd + min)
If (InStr(1, result, "," & RndNumber & "," ) = 0) Then
result = result & RndNumber & ","
cnt1 = cnt1 - 1
result = Left(result, Len(result)-1)
result = Right(result, Len(result)-1)
RandomUnique = result
