Problems calling a web service from an .aspx page

[Sanjeet1]

When I call my web service from a web service I use this line of code:

ImageDB(0) = WS.RetreiveImageDB(userid, patientid, recordid)

This is the format of my web service:

<WebMethod()> _
Public Function RetreiveImageDB(ByVal uid As String, ByVal pid As String, ByVal rid As String) As Byte()

' MY code

Return b


End Function

This is the error message I get:


Input string was not in a correct format.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.FormatException: Input string was not in a correct format.

I meant calling from a web page sorry. I don't have a problem passing in the parameters its only when the byte array gets returned I get the error message.
