Hi,

I have a 3 tier architecture
My Front tier calls a webservice
ObjGeneral.getAttachment(p_cFileName)
Which calls the business rule tier and then fires off the code in the
dataAccess tier to
attach the file using WSE Dime and send to the front end.
However my problem seems to be
I cannot access the context of the webservice so I can read the stream
In the MS Article
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wseref/html/T_Microsoft_Web_Services2_RequestSoapContext.asp

"When a one-way Web service method is hosted by ASP.NET, the Web service
method cannot access the SoapContext using the Current property. To gain
access to the SoapContext for one-way methods, the class implementing the Web
service should inherit from the System.Web.Services.WebService class and
include code in the one-way method to get the
System.Web.Services.WebService.Context property."

how do you do this ie access the context

my code is as follows

objGeneral.streamServerAttachment(p_nIdClient, _
p_cReportFile, _
lnMimeType, _
p_lTaxReport)

objStream = SoapContext.Current.Attachments(0).Stream

objBinaryStream = New BinaryReader(objStream)
lnStreamlength = CInt(objBinaryStream.BaseStream.Length)
objBinaryStream.BaseStream.Read(objData, 0, lnStreamlength)


TIA

Stu

Hi Stu,

I'm not sure I understand what you're attempting exactly. It seems to me
that a one-way call cannot satisfy your requirement to return data in an
attachement because a one way call cannot return data.

Am I missing something?
