Thank you Michael, but actually I'm trying to open a PDF via URL (e.g. http://www.terna.com/fileadmin/user_upload/Partner/Dokumente/terna_QV11_Whats_new_in_QV_11_de.pdf)
And: the PDF should be opened in Adobe Reader, rather than browser.
The main reason is: we have disabled all Internet Explorer toolbars (tabs, adress bar etc.) for our Qlikview environment. So, if the user opens a QV application, he just sees the IE title bar + the QV application itself.
Linking to a pdf via "Open URL" action opens the file in a new IE tab and now the user has no evident way to switch between the "QV tab" and "pdf tab" (due to the missing tab bar) ... You see what I mean?
There is a way to do that in a macro where the pdf will be downloaded then opened with adobe.
But I did not test on server, just on qv desktop.
Here's the sample macro in vbscript where you'll change the paths accordingly, hope it'll be helpful:
pdfurl = "weburl/yourpdffile.pdf"
savepath = "C:\Users\Test\Desktop\QVW\File.pdf"
adobepath = "C:\Program Files (x86)\Adobe\Acrobat 10.0\Acrobat\Acrobat.exe"
set objHTTP = CreateObject("Microsoft.XMLHTTP")
set objPDF = CreateObject("Adodb.Stream")
objHTTP.Open "GET", pdfurl, False
objPDF.Type = 1 'binary
objPDF.SaveToFile savepath, 2 'overwrite
'below can be set from launch trigger
set app = ActiveDocument.GetApplication
app.Launch adobepath, savepath
Make sure to change the security flag to "Allow system access".
