Force PDF Download is OK, Popup Remains Open on Win2k?

I've successfully forced a PDF to come up with a file download box.  The popup on XP SP2 with all IE updates works perfect, it opens a 100x100 pixel box in the lower right of the screen, after you hit the save button the file downloads and the popup closes.  I see hidden popups are not allowed offscreen anymore with all the new IE updates.

On another PC with win2k, the popup box is hidden off screen, the file downloads OK, but the popup doesn't close after the file is downloaded successfully.  Attempted to use <<body onLoad="window.close();"> but it seems that using the CFHEADER AND CFCONTENT tages forces everything else to be ignored.


Here I am calling act_download_pdf.cfm with the filename attached to the URL

<a href="JavaScript:void(window.open('#request.str_common_directory#act_download_pdf.cfm?str_filename=#request.sct_pdf["str_file_name#int#"]#','download','width=100,height=100,left=5000,top=5000,location=no,menubar=no,status=no,toolbar=no, scrollbars=no, resizable=no'));">Download</a>


Then in the act_download_pdf.cfm I have the following code to force the PDF to open a Save As box

<CFOUTPUT>

<CFSET variables.str_filepath = "#request.str_server_root#documents/">
<CFSET variables.str_filename = "#request.str_filename#">
<CFSET variables.str_fullpath = "#variables.str_filepath##variables.str_filename#">

<CFHEADER NAME="content-disposition" VALUE="attachment; filename=#variables.str_filename#">
<CFCONTENT TYPE="application/pdf" FILE="#variables.str_fullpath#" DELETEFILE="no" RESET="no">

</CFOUTPUT>

Is there anyway to make sure the popup closes by itself, or is there another work around besides using Zip files?  Not sure if I should post this is a javascript forum, thought I'd ask the CF masters prior to doing so.  Thanks for any help in advance.

That's a tough one. I don't know Javascript enough to know the in's and out's of popups and closing. As an alternative, you may want to consider using iFrames on the same page instead of poping up a window for the content download. If the popup window is solely for the purpose of downloading a PDF document, I would suggest using iFrames (the iFrame could be a 1px x 1px frame with code in it).

I think this is the way to force a window to after popping up with javascript. Not positive though.

<body onLoad="window.close()'>

<script>
newWin = window.open('#request.str_common_directory#act_download_pdf.cfm?str_filename=#request.sct_pdf["str_file_name#int#"]#','download','width=100,height=100,left=5000,top=5000,location=no,menubar=no,status=no,toolbar=no, scrollbars=no, resizable=no');
</script>

<a href="javascript:newWin.close();">Close</a>
Hi,
after this code on act_download_pdf.cfm - just write
<SCRIPT LANGUAGE="JavaScript" TYPE="text/javascript">
<!--
      window.close();
//-->
</SCRIPT>


eg: =======================================================================

<CFOUTPUT>

<CFSET variables.str_filepath = "#request.str_server_root#documents/">
<CFSET variables.str_filename = "#request.str_filename#">
<CFSET variables.str_fullpath = "#variables.str_filepath##variables.str_filename#">

<CFHEADER NAME="content-disposition" VALUE="attachment; filename=#variables.str_filename#">
<CFCONTENT TYPE="application/pdf" FILE="#variables.str_fullpath#" DELETEFILE="no" RESET="no">

</CFOUTPUT>

<SCRIPT LANGUAGE="JavaScript" TYPE="text/javascript">
<!--
      window.close();
//-->
</SCRIPT>

that shld do it

K'Rgds

anandkp - that still doesn't work for me, seems that when CFHEADER and CFCONTENT are used, it ignores all other code in that file. So far the only way I've found to get it to close is to put a timer on the popup prior to it opening.

I left the act_download_pdf.cfm as is for now.

Then changed the popup script to this:

<SCRIPT language="javascript">
   <!--
   function windowOpener(url, name, args)
   {
   childWin = window.open(url,name,args);
   }
   var t;
   t = setTimeout("childWin.close()",10000);
   t = setTimeout("childWin.close()",20000);
//-->
</SCRIPT>

Then the link is:

<div class="small"><a href="JavaScript:void windowOpener('#request.str_common_directory#act_download_pdf.cfm?str_filename=#request.sct_pdf["str_file_name#int#"#', '#int#', 'width=100,height=100,left=5000,top=5000,location=0,menubar=0,status=0,toolbar=0,scrollbars=0,resizable=0');">Download</a></div>

With it this way, the window will try to close after 10 and 20 seconds.  Only problem with this is that the timer is pretty chessy, if you click on multiple downloads, the timer starts over and the previous box will not close.

Any know how to setup a coldfusion timer in session so each download box will have a unique timer that keeps trying to close the window no matter how long it takes to download?
Is the popup window only for prompting this file for download? Is there any other purpose for the popup window?
blackOps - yeah im passing the file name to the act_download_pdf.cfm. I tried it both ways with just a new blank window and a popup, same results occur on win2000, the new window/popup doesn't close after the file finishes downloading.  If there's a way to invoke the download dialog box without a new window, that would be better.
How bout this? To test this, save a file called test.pdf on your c:\ drive. You will replace those paths and file names in your application though.

<cfif IsDefined("URL.FileName") AND FileExists(ExpandPath('.\') & "#URL.FileName#")>
<CFHEADER NAME="content-disposition" VALUE="attachment; filename=#ExpandPath('.\') & "#URL.FileName#"#">
<CFCONTENT TYPE="application/pdf" FILE="#ExpandPath('.\') & "#URL.FileName#"#" DELETEFILE="no" RESET="no">
</cfif>

<cfoutput>
<a href="test.cfm?FileName=#URLEncodedFormat("test.pdf")#">Test Text File</a>
</cfoutput>

anandkp - funny enough, I based my code off the link you provided. I guess it all started going wrong when i first used a target="_blank" on the link then thought too much into it from there.  I got rid of popup all together and used the standard link like you said.  Thanks.
Glad to help u sort it out ...

Cheers :)
