below is the code to create a random password... to email it, search for aspmail on google and this will guide you through the process.
<% 'Generate a random password
Sub StrRandomize(strSeed)

Dim i, nSeed



nSeed = CLng(0)

For i = 1 To Len(strSeed)

nSeed = nSeed Xor ((256 * ((i - 1) Mod 4) * AscB(Mid(strSeed, i, 1))))

Next



'Randomiser

Randomize nSeed

End Sub

Function GeneratePassword(nLength)

Dim i, bMadeConsonant, c, nRnd



'You may adjust the below constants to include local,

'eg. scandinavian characters. This way your passwords

'will not be limited to latin characters.

Const strDoubleConsonants = "bdfglmnpst"

Const strConsonants = "bcdfghklmnpqrstv"

Const strVocal = "aeiou"



GeneratePassword = ""

bMadeConsonant = False



For i = 0 To nLength

'Get a random number number between 0 and 1

nRnd = Rnd

'Simple or double consonant, or a new vocal?

'Does not start with a double consonant

'15% or less chance for the next letter being a double consonant

If GeneratePassword <> "" AND (bMadeConsonant <> True) AND (nRnd < 0.15) Then

'double consonant

c = Mid(strDoubleConsonants, Int(Len(strDoubleConsonants) * Rnd + 1), 1)

'response.write int(Len(strDoubleConsonants) * Rnd + 1)

'response.write "<br>"

c = c & c

i = i + 1

bMadeConsonant = True

Else

'80% or less chance for the next letter being a consonant,

'depending on wether the last letter was a consonant or not.

If (bMadeConsonant <> True) And (nRnd < 0.95) Then

'Simple consonant

c = Mid(strConsonants, Int(Len(strConsonants) * Rnd + 1), 1)

bMadeConsonant = True

'5% or more chance for the next letter being a vocal. 100% if last

'letter was a consonant - theoreticaly speaking...

Else

'If last one was a consonant, make vocal

c = Mid(strVocal,Int(Len(strVocal) * Rnd + 1), 1)

bMadeConsonant = False

End If

End If

'Add letter

GeneratePassword = GeneratePassword & c

Next



'Is the password long enough, or perhaps too long?

If Len(GeneratePassword) > nLength Then

GeneratePassword = Left(GeneratePassword, nLength)

End If

End Function

StrRandomize CStr(Now) & CStr(Rnd)

%>

<% 'create a 7 digit password and store in varPassword
Dim varPassword
varPassword = GeneratePassword(7)
%>
