I don't think you'll be able to do this.  Most browsers will not allow the contents of a file on the users local file system to be accessed directly from the browser, as this is a huge security risk (essentially it would allow malicious javascript to pull back the contents of files at will).  Also, even if you add a file URL to your web tab, a lot of browsers will block that too.  For example, Mozilla browsers won't action file URLS from a page served via HTTP.  They appear, but if you click on them nothing happens.

Is there a reason why you can't upload the file to Salesforce?

Hi Bob,

Thanks for your reply.

What I have done is from qlikview I login to salesforce apps to get the data from accounts table (for example) and I have saved into a .qvw file on my desktop.  This file also contain the salesforce login details. This is from Qlikview to salesforce.

Then in salesforce create a page and a corresponding tab.  Login to salesforce and click the tab the file saved on my desktop will be opened.  I tried the below sample script in the page i created after making changes.  This page supposed to open the file from the server, and after refreshing, i will get the updated dashboard with the latest info. not sure this is because I am using qlikview personal edition.

<apex:page >
<iframe height="1000px" width="1500px" id="<PageName>" name="<PageLabel>"
src="http://<AccessPointServer>/QvAJAXZfc/opendoc.htm?document=<account.qvw>&host=
AccessPoint%20Documents"></iframe>
</apex:page>

This is the syntax not working,  This instruction I got from Qlikview setup and integration document

Thanks
