I have a .NEt web service that takes a bytearray and writes it out to
a file.
<WebMethod()> _
Public Function ProcessRequest(ByVal f() As Byte, ByVal filename
As String) As String
Try
' instance a memory stream and pass the byte array
' to its constructor
Dim ms As New MemoryStream(f)
' instance a filestream pointing to the
' storatge folder, use the original file name
' to name the resulting file
Dim fs As New FileStream
(System.Web.Hosting.HostingEnvironment.MapPath("~/images/") &
filename, FileMode.Create)
ms.WriteTo(fs)
' clean up
ms.Close()
fs.Close()
fs.Dispose()
' return OK if we made it to here
Return "OK"
Catch ex As Exception
Return ex.Message.ToString()
End Try
End Function
This works fine in a aspx web page but I want to use it in a flex
application. I can add the service to my application:
mx:WebService id="UploadService" wsdl="http://
fileuploader.cityofencinitas.org/?WSDL" result="__completeHandler
(event)" fault="__faultHandler(event)" useProxy="false">
mx:operation name="ProcessRequest" >
<mx:request>
f>
{uploadByteArray}
/f>
fileName>
{txtFileName.text}
/fileName>
/mx:request>
/mx:operation>
/mx:WebService>
I I use it like this:
uploadByteArray = new ByteArray;
jpg = new JPEGEncoder(75);
var bitmapData:BitmapData = new BitmapData
(uploadimage.width,uploadimage.height);
bitmapData.draw(uploadimage);
var quality:int = 75;
uploadByteArray = jpg.encode(bitmapData );
UploadService.ProcessRequest.send
Unfortunately nothing happens. No error messages and no file is
uploaded to the server. Can anybody help me figure out what is going
wrong?
