I have created a random password generator function in asp.net (vb.net). How do i call this function through my asp.net button???
:cry:

Function RandomPW(ByVal myLength)
'These constant are the minimum and maximum length for random
'length passwords. Adjust these values to your needs.
Const minLength = 6
Const maxLength = 20

Dim X, Y, strPW

If myLength = 0 Then
Randomize()
myLength = Int((maxLength * Rnd()) + minLength)
End If


For X = 1 To myLength
'Randomize the type of this character
Y = Int((3 * Rnd()) + 1) '(1) Numeric, (2) Uppercase, (3) Lowercase

Select Case Y
Case 1
'Numeric character
Randomize()
strPW = strPW & Chr(Int((9 * Rnd()) + 48))
Case 2
'Uppercase character
Randomize()
strPW = strPW & Chr(Int((25 * Rnd()) + 65))
Case 3
'Lowercase character
Randomize()
strPW = strPW & Chr(Int((25 * Rnd()) + 97))

End Select
Next

RandomPW = strPW

End Function

are you trying to put it on the aspx page or in the codebehind?

make it a static function in a class (say Utilities) then in your click event in code behind just call Utilities.RandomPW(7). But you need to return the password you generated.

No you copied it without understanding it again. There is no way that you could have thought up that code and coded it and then not know how to call a function.
