Read asp.net web service file stream using Javascript

[olisemalis]

Hello,

I have an asp.net web service, that is sending a filestream in a web output method.

Is it possible to read/render this file stream in a html page using javascript? I know hot to call the service using javascript. However, I want to get the filestream and read it on the fly without needing to save it on the disk.


Any example?


Thank you

hmmm.. I sorda do something similar .. maybe it can give you ideas to help you out.

I have a dropdown list that makes the initial web service call..
<aspropDownList ID="DropDownList1" runat="server" onchange="GetData()"> </aspropDownList>

(Note I am using AJAX)

I basically create a dataset from my web service call

Webserivce.WebMethod_GetObject()
this returns an object which I create a dataset from with that dataset I...

Dataset.WriteXML(response.outputstream)
response.end()

on the calling page I...

//Retrieve the information for the new rows

request.onreadystatechange = ReceiveRows;

request.open("GET", "AjaxGetData.aspx");

request.send(null);

In receive rows function I have...

// get the information in the XML document

var xml = request.responseXML;

var dataRows = xml.getElementsByTagName(TableName.toUpperCase());

I remove then create new data rows.. this does not sound exactly like what you are doing.. but maybe it will give idea to try

Good luck!
