Set binary/base64 data as attachment in VB Script CDO.Message - iis

Question

I am trying to send out an email with attachment as PDF. I have my attachment data in binary/Base64, but when I am trying to write this to the stream, it is not working. Here is my code. I am using upload class from here - http://www.codeguru.com/csharp/.net/net_asp/article.php/c19297/Pure-ASP-File-Upload.htm
<!--METADATA TYPE="TypeLib" FILE="C:\windows\system32\cdosys.dll" -->
<!-- #include file="upload.asp" -->

' Create the FileUploader
Dim Uploader, File
Set Uploader = New FileUploader
' This starts the upload process
Uploader.Upload()
Dim uploadFileName
Dim uploadFileData
' Check if any files were uploaded
If Uploader.Files.Count > 0 Then
' Loop through the uploaded files
For Each File In Uploader.Files.Items
uploadFileName = File.FileName
uploadFileData = File.FileData
Next
End If
Set ObjMailer = CreateObject("CDO.Message")
Set iConf = Server.CreateObject("CDO.Configuration")
Set Flds = iConf.Fields
With Flds
.Item(cdoSendUsingMethod) = cdoSendUsingPort
.Item(cdoSMTPServer) = "localhost"
.Item(cdoSMTPServerPort) = 5000
.Item(cdoSMTPconnectiontimeout) = 10
.Update
End With
Set ObjMailer.Configuration = iConf
ObjMailer.Subject = "Subject"
ObjMailer.From = "from#testdomain.com"
ObjMailer.To = "to#testdomain.com"
ObjMailer.HTMLBody = "<h1>This is a sample html email body</h1>"
' Code to Attach the Email
Const cdoContentDisposition = "urn:schemas:mailheader:content-disposition"
Dim oPart : Set oPart = ObjMailer.Attachments.Add
oPart.ContentMediaType = "application/pdf"
oPart.Fields(cdoContentDisposition).Value = "attachment;filename=""Test.pdf"""
oPart.Fields.Update
Dim oStreamOut: Set oStreamOut = oPart.GetDecodedContentStream
oStreamOut.Type = 1
oStreamOut.Write uploadFileData
oStreamOut.Flush
ObjMailer.Send
Set ObjMailer = Nothing
Set iConf = Nothing
Set Flds = Nothing
If Err.number <> 0 Then
Response.Write "Error: " & Err.Number
Response.Write "Error (Hex): " & Hex(Err.Number)
Response.Write "Source: " & Err.Source
Response.Write "Description: " & Err.Description
End If
I get following error. I don't know where am I getting wrong.
ADODB.StreamDescription: Arguments are of the wrong type, are out of acceptable range, or are in conflict with one another.
Can somebody help?

Finally, I got this working. Thanks to kul-tigin for pointing the issue for vbArray + vbByte. The data uploaded is multi-byte data and I need to normalize it.
Here is the function I got here to convert the multi-byte array.
Function GetFileDataBinary()
Dim RS, LMultiByte, Binary
Const adLongVarBinary = 205
Set RS = CreateObject("ADODB.Recordset")
LMultiByte = LenB(FileData)
If LMultiByte > 0 Then
RS.Fields.Append "mBinary", adLongVarBinary, LMultiByte
RS.Open
RS.AddNew
RS("mBinary").AppendChunk FileData & ChrB(0)
RS.Update
Binary = RS("mBinary").GetChunk(LMultiByte)
End If
GetFileDataBinary = Binary
End Function
I changed my code like below and it worked just seemlessly.
Dim uploadFileName
Dim uploadFileData
' Check if any files were uploaded
If Uploader.Files.Count > 0 Then
' Loop through the uploaded files
For Each File In Uploader.Files.Items
uploadFileName = File.FileName
uploadFileData = File.GetFileDataBinary
Next
End If
I can call File.GetFileDataBinary because I put my GetFileDataBinary in my upload.asp.
