Hi, thanks for your reply, Richard.
I RDP'd to the server console, but no error pops up. I allowed IIS to
interact with the desktop, but I didn't change anything.
I might have found the problem: the file I am trying to open has
external links. With a "normal" file it works fine whatever way I run
the script.
That's why I used the second argument (UpdateLinks) in the Open call
documented here (2 means "Never update links for this workbook on
opening"):
http://msdn.microsoft.com/en-us/library/microsoft.office.interop.excel.w
orkbooks.open(office.11).aspx
Apparently, the argument I passed (2 of PHP type integer) is invalid.
Let me explain why I think so:
In the following, I am running everything from
http://localhost/test.php, which allows user interaction.
If I put $excelApp->Visible = 0 and use 2 as the UpdateLinks argument to
Open, everything runs fine without any interaction with the user.
If I put $excelApp->Visible = 1 and use 2 as the UpdateLinks argument to
Open, Excel shows up and tells me the links could not be updated, which
means it tried to update it, which is NOT the expected behaviour!
The values 1, 2 and 3 all give the same result, which is contradictory
with the documentation (1 is "ask", 2 is "do not update" and 3 is "do
update").
If I put 0, Excel shows up and closes without any interaction, but 0 is
not an authorised value according to the documentation.
Any other value crashes the script.
If I don't specify this argument, Excel shows up and asks me if I want
to update, which is the expected behaviour.
According to the documentation, this UpdateLinks argument is an Object,
maybe that's where the problem lies? If so, how can I create the object
to be passed as an argument to Open?
By the way, just out of curiosity, I tried to use the value 0 and run
the script from a client computer, but it is still blocked in the way
described above.
Thanks for your help !
