Hi, I've just setup a new server with the latest chilkatupload.dll. For some reason the server isn't seeing the files or form values being posted. Everything looks fine from a code point of view... any ideas?
Found the answer for this. In IIS7, you need to change the ASP / maxRequestEntityAllowed setting to > 200KB if you want to upload files larger than that. Otherwise the uploadrcv object returns a null POST.
I tested with v9.4.1, and also with Chilkat's latest internal pre-release:
and in both cases, everything worked fine.
To ensure the HTTP request (i.e. the multipart/form-data) is a correct and valid one, send it with a browser via a simple HTML form such as this:
<html> <body> <form method="POST" enctype="multipart/form-data" action = "http://www.yourdomain.com/yourScript.asp" > <input name=hid1 type=hidden value="test123"> <input name=hid2 type=hidden value="abcdef"> <input name=attach1 type=file size=20> <input type=submit value="Upload"> </form> </body> </html>
My receiving ASP script looks like this:
<% @CodePage = 65001 %> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> </head> <body> <% ' The Chilkat ASP Upload component is freeware. ' The UploadRcv object receives uploads in ASP. ' It can be used to save uploaded files to the web server, ' or to save directly to memory for immediate access. set receiver = Server.CreateObject("Chilkat.UploadRcv") ' Stream uploads to a directory: 'receiver.SaveToUploadDir = 1 ' receiver.UploadDir = Server.MapPath("receivedData") ' Don't allow anything over 1MB receiver.SizeLimitKB = 1000 ' Set a timeout just in case something hangs ' This is a 20-second timeout: receiver.IdleTimeoutMs = 20000 ' Consume the upload. Files are streamed to the UploadDir success = receiver.Consume() Response.Write receiver.LastErrorHtml If (success = 0) Then Response.Write receiver.LastErrorHtml Else ' Display the files received: Response.Write "<p>Num file received: " & receiver.NumFilesReceived & "</p>" If (receiver.NumFilesReceived > 0) Then For i = 0 To receiver.NumFilesReceived - 1 Response.Write "<p>Received " & receiver.GetFilename(i) & " (" & receiver.GetFileSize(i) & " bytes)</p>" Next End If Response.Write "<p>Success.</p>" End If Response.Flush() %> </body> </html>
