Re: [python-win32] Problem creating a shortcut

[Tim Golden]

Sorry, missed this one going through. Looks like
Roger's hit the nail on the head, though. Bizarre
behaviour by the IShellLink interface: I can't find
any kind of reference to this but I assume that
since the Path attribute of the link should *only*
contain an executable, there's no need for the
quotes -- which then confuse it when they're there
as it tries to make the executable into an absolute
path.

One small comment, Mike. Since you're using the
winshell module -- which I assume is the one from
my site -- why not use its CreateShortcut function?
It's basically just a light wrapper around the IShellLink
functionality which someone else mentioned:


import os, sys
import winshell

winshell.CreateShortcut (
Path=os.path.join (winshell.desktop (), "shortcut.lnk"),
Target=r"c:\Program Files\Mozilla Firefox\firefox.exe",
Arguments="http://localhost";,
Description="Open http://localhost with Firefox"
)



But maybe you're using the WScript.Shell functionality
elsewhere as well?

Hi,

I've had this niggling issue from time to time. I want to create a
shortcut on the user's desktop to a website that specifically loads
Firefox even if Firefox is not the default browser.

I usually use COM as it allows very specific settings of the shortcut,
such as the Working Directory and the Target Path. However, the
following will not work for some reason:



import win32com.client
import winshell

shell = win32com.client.Dispatch('WScript.Shell')
userDesktop = winshell.desktop()

shortcut = shell.CreateShortCut(userDesktop + '\\MyShortcut.lnk')
shortcut.Targetpath = r'"C:\Program Files\Mozilla Firefox\firefox.exe"
https:\www.myCompanyWebsite.com\ 
auth\preauth.php'

shortcut.WorkingDirectory = r'C:\Program Files\Mozilla
Firefox'
shortcut.save()



This creates the following target path (which doesn't work for 
obvious reasons) in the shortcut's Target Path. The extra "C:\" is 
getting in there somehow...


"C:\"C:\Program Files\Mozilla Firefox\firefox.exe" https:
\www.myCompanyWebsite.com\ 
auth\preauth.php"


If I leave the website off the TargetPath, it works. If I take the 
path to Firefox
out of the TargetPath, it works too. Is there another method I can 
use other than

creating the shortcut by hand and using the shutil module?

Thank you for any ideas.

Mike


I think you need to put the URL in shortcut.Arguments rather than
appending it to the executable path.

 Roger





Someone on c.l.py pointed this out too. I was unaware that that existed. 
It works great though. Thanks a lot!

Do you understand that it is not safe to assume that Firefox lives in 
"C:\Program Files\Mozilla Firefox"?  I often override my application 
install directories to keep the paths short, so I put it in 
"C:\Apps\Firefox".  Plus, the "Program Files" path name is localized 
on the international versions of Windows.


I guess I should have described my environment a little more. This is 
for a logon script at a business. The user's have no control over where 
Firefox resides and if they happen to uninstall it or do not have it in 
the first place, one of my other scripts will install it for them in the 
background.


The reason is quite simple. We use Zimbra which runs much better in 
Firefox than any other browser we've tested. But you and the others are 
correct. If this had been an application, then I wouldn't have done this 
the way that I am.




You'll need to dig in the registry, in 
HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Mozilla Firefox.  Fetch the 
"CurrentVersion" string value, then look inside that key, in Main, and 
fetch the PathToExe string.  Something like this:


ffkey = _winreg.OpenKey( _winreg.HKEY_LOCAL_MACHINE, 
'SOFTWARE\\Mozilla\\Mozilla Firefox')

ffver = _winreg.QueryValueEx( ffkey, 'CurrentVersion' )[0]
print ffver
ffmainkey = _winreg.OpenKey( ffkey, sub + "\\Main" )
ffpath = _winreg.QueryValueEx( ffmainkey, 'PathToExe' )[0]
_winreg.CloseKey( ffkey )
_winreg.CloseKey( ffmainkey )



Thanks for the advice,

[python-win32] Volume Serial Number

Re: [python-win32] Volume Serial Number

[Tony Cappellini]

That's not the serial number of the drive- as assigned by the drive
manufacturer.

If you want the SN from the drive manufacturer, you will need to issue an
IOCTL ATA Passthrough command which sends the  ATA Identify Device command
to the drive. Unless the Winapi has a wrapper for that functionality, you
can't do that via Python.

You would have to install the Windows SDK to compile a tiny program to issue
the Identify Device command and pull out the SN from the data coming back,
which is only 512 bytes.

This would have to be written in C. It's not difficult to do and the program
would only require less than100 lines of C code.

Yes, actually, it does.  The second item in the tuple it returns is the 
VSN as a 32-bit binary value.


You were probably confused because Python showed it to you as a signed 
decimal integer.  If your VSN is really -, then it probably 
showed you -65535.  If you print that in hex, you get -, and if you 
treat that as unsigned, you get .


I wish I knew a better way to do the signed/unsigned mangling, but try this:

   def UnsignedHex( v ):
   if v >= 0: return '%08X' % v
   return '%08X' % (0x1 + v )
   print UnsignedHex( win32api.GetVolumeInformation('C:\\')[1] )

Good point. I am using your module (thanks!). Somehow I missed it's 
shortcut creating abilities. I do use the WScript.Shell earlier in my 
script, but I think it's just for other types of shortcut creation.


I'll have to look. It would be good not to have to import extra stuff.

This example also worked quite well. In addition to that there's lots of
juicy information available from the 'volume' object. Thanks for that!

Thanks for that as well, although not what I was looking for, I'll save
that for a rainy day. :)

Just for message consistency, I've reposted Tim Robert's example below:

def UnsignedHex( v ):
if v >= 0: return '%08X' % v
return '%08X' % (0x1 + v )
print UnsignedHex( win32api.GetVolumeInformation('C:\\')[1] )

Interesting because of course WMI can be used to do so many
things remotely that it might be considered a security risk.
You can secure it down to namespace level but no lower than
that, I think: if a user has access to, say, view Volume labels,
then they can create new processes (altho' there are privilege
implications on some such things).

In short, though, I've never heard of an environment where it
is disabled since its potential for remote administration and
so on is so useful.
