and the string must be like this

 

<new>

 

<user_new_password>User New Password</user_new_password>

 

<user_old_password>User Old Password</user_old_password>

 

<user_email> UserName@DomainName </user_email>

 

<source>M Signup</source>

 

<user_ip>10.0.0.1</user_ip>

 

</new>

 

when i pass the newpassword i pass it with this fucntion

 

Public Function GetRandomString(ByVal numberOfCharacters As Integer) As String

 

Dim r As New Random

 

Dim b(numberOfCharacters) As Byte

 

For x As Integer = 0 To numberOfCharacters - 1

 

b(x) = r.Next(97, 122)

 

Next

 

Return System.ASCIIEncoding.ASCII.GetString(b)

 

End Function

 

when i do this i always get this error when i try to call the web service

 

'', hexadecimal value 0x00, is an invalid character

Could you show the code for the actual WebMethod?

unfortunately i'm not the owner of the web services i only have the parameters

Do you have access to the .wsdl file of the web service? Could you post the code where you are calling the service?
