asp_web_howto thread: Executing VBScript from ASP
Message #1 by "O. Mortensen" <orla-67@i...> on Tue, 16 Jul 2002 11:33:08

Hi
As a client/browser, I want to call page2.asp, which has 2 functions:
1) Execute page3 VBS or ASP (Updating Oracle DB, generating PDF etc.)
2) Redirect to page4.asp
Executing page3 takes a while, so I don't want the client to wait
for completion. It has no screen output to the client, so it could
be run at my webserver (WIN2000/IIS5)
What is the best solution in this case ?
Is this approach in page2.asp possible, and is there any security breach ?
<%
set wshell = Server.createobject("wscript.shell")
wshell.Run "c:\winnt\system32\cscript.exe
D:\Application\Inetpub\wwwroot\cgi-bin\page3.vbs"
set wshell = nothing
%>
As a client, the script is executed as IUSR_MACHINENAME, which I am not
sure is allowed on the server.
I hope someone can help me with these questions
Thanks
Orla

Hmmm, using an MTS package with MSMQ will allow asynchronous processing on
the long query without losing the thread. Most of this type of situation is
called from a frames page so the client is always connected while waiting
for one page to finish. When it does, it can then redirect and show the new
page in the frames.

Thanks Tom
Page3 makes a 10 pages PDF document, without the customers knowledge.
So I want to "bypass" page3 and go straight to page4.asp (redirect).
Page4.asp is the last page in the proccess, so I guess the customer closes
the browser when page4 is received.
When I fire CSCRIPT..... in a CMD on my server, as Administrator, it runs
just fine.
When I call page2.asp as a client, it seems like, I am not authorized to
do so.
Can anyone confirm it's a problem, and maybe come up with an alternative.
Thanks

Check that the machine has permissions for "script" under web sharing for
the folder where the script resides. For win2k use IUSR_TEMPLATE for the
machine name.
I think you just need a function which launches the pdf process that returns
a boolean letting you know it's started that's called from page4.asp. If
this returns true, the rest of page4 gets executed, if not, you need an
error handler for the pdf not working.

Page3.vbs resides in cgi-bin, where Everyone has execute permission. In the
same lib, customers execute .EXE files with out problems.
I generate the PDF document (later on 2 og 3 documents), and e-mails the
document, and other documents as attatchments. It works perfect on the
server.
On page4.asp I don't need to get a status from the PDF process.
How do you launch the PDF process ?

Hmmm, "Everyone" doesn't include machines only users, for asp to call the
*.exe, the folder needs the machine to have explicit script permissions to
it.
Creating pdf's is usually adobe software, although there are some components
that can output pdf's. To launch it, you can use a cscript/wscript...
