Question

Rather than using a Handler(.ashx), is it possible to use a web service(.asmx) to upload?

Any suggestions on how to use a jQuery upload to get the input stream?

VB.NET code or examples would be appreciated.

Answer 1

Yes it is possible ,
you can pass the File to the service(.asmx) , and get Json back by specifing the response type.
better soultion if you want a simple uploader with drag and drop functionality would be
Ajax uploader – valums

_uploader = new qq.FileUploader({
                element: document.getElementById(_Uploaddiv),
                onComplete: function (id, fileName, responseJSON) {  },
                action: '/Uploader.asmx/functionName',
                params: {
                    startRowIndex:_startRowIndex,
                    pageSize:_pageSize
                }

    xhr.setRequestHeader("X-Requested-With", "XMLHttpRequest");
    xhr.setRequestHeader("Accept", "application/json, text/javascript, */*; q=0.01");

set the XMLHttpRequest() headers to Accept json

VB code

<WebMethod()> _
<ScriptMethod(ResponseFormat:=ResponseFormat.Json)> _

Simple , light, accepts my CSV and gets me the result. that’s what i wanted
