I have an application which shows some static files for download. This application creates an hidden iframe and set the source to the file-url.
The browser shows a save-as dialog.
But within Microsoft Office there is no save-as dialog and the filedownload is not started.
The file is served with Content-Disposition: Attachment. The working solution will simply open a new browser instance and trigger the file download. I don't want to open a new window which will gain focus.
<!DOCTYPE html> <html> <head> <script> function di(){ document.getElementById("d").src="blob.dat"; } </script> <title>download</title> </head> <body> <h1>file loading</h1> <h2>works</h2> <p>But opens a new window</p> <a href="blob.dat" target="_blank"> a blank </a><br> <a href="blob.dat" target="download"> named frame </a> <h2>won't work</h2> <a href="blob.dat"> a self </a><br> <a href="blob.dat" target="_self"> a self </a><br> <a href="blob.dat" target="_top"> a top </a><br> <a href="#" onclick="di();"> iframe </a><br><br> <iframe id="d"></iframe> </body> </html>
I think it is a serius bug, if a web-application is unablle to follow links.
<script language="javascript"> function OpenADocument(strDoc) { document.blob.hidFLID.value=strDoc; document.blob.action = "OpenLinksDocument.asp"; document.blob.method="post" document.blob.submit(); } </script>
---- ASP Code ----
Private Sub DownloadFile(file, MainFileName) '--declare variables Dim strAbsFile Dim strFileExtension Dim objFSO Dim objFile Dim objStream, FileNM strAbsFile = Server.MapPath(file) Set objFSO = Server.CreateObject("Scripting.FileSystemObject") If objFSO.FileExists(strAbsFile) Then Set objFile = objFSO.GetFile(strAbsFile) strFileExtension = LCase(objFSO.GetExtensionName(file)) '-- first clear the response, and then set the appropriate headers Response.Clear '-- the filename you give it will be the one that is shown ' to the users by default when they save dim NewFileName NewFileName= "RandomFileNameYouWishtoGive" & Session.SessionID &"." &strFileExtension Response.AddHeader "Content-Disposition", "attachment; filename=" & NewFileName Response.AddHeader "Content-Length", objFile.Size Response.ContentType = "application/octet-stream" Set objStream = Server.CreateObject("ADODB.Stream") objStream.Open '-- set as binary objStream.Type = 1 Response.CharSet = "UTF-8" '-- load into the stream the file objStream.LoadFromFile(strAbsFile) '-- send the stream in the response Response.BinaryWrite(objStream.Read) objStream.Close Set objStream = Nothing Set objFile = Nothing Else 'objFSO.FileExists(strAbsFile) Response.Clear Response.Write("No such file exists.")

-----------------------------------`` Explanation: 1) On You Link page Don't mention Your File name in Anchor tag, 2) instead pass some Encrypted Code or Encrypted File name itself 3) On Page where you are posting File name, Do Form Request for value hidden File ID - hidFLID 4) now use that File name and Add that File name to Response header. 5) This will not show your Actial File Name enter code here`me/File Path 6) Above Example i have specified is in Classic ASP, If you mention your Web - technology, i may help to provide code in that Tech.
