Thanks again for your help. I tried something similar to what you suggested:
def run_app(self, app_path):
args = shlex.split(app_path.replace("\\", "\\\\"))
args = [arg.replace("\\\\", "\\") for arg in args]
args[0] = os.path.expandvars(args[0])
try:
if pywin32:
exe = win32api.FindExecutable(args[0])[1]
if exe != os.path.abspath(args[0]):
args.insert(0, exe)
subprocess.Popen(args)
except Exception:
return False
return True
where pywin32 is a global variable defined earlier in my program based on whether or not the win32api module is available.
This code generally works quite well, but with one problem. I have in my XML file a line like this:
<app name="Notepad++" checked="false">%ProgramFiles%\Notepad++\notepad++.exe C:\Users\Timothy\Documents\Python\StartupPlus\apps.xml</app>
Within the try statement, the variable 'args' contains this list, as expected:
['C:\Program Files (x86)\Notepad++\notepad++.exe', 'C:\Users\Timothy\Documents\Python\StartupPlus\apps.xml']
But the 'exe' variable returned by win32api.FindExecutable is not what I would expect:
C:\PROGRA~2\NOTEPA~1\NOTEPA~1.EXE
Because of this, the boolean comparison:
if exe != os.path.abspath(args[0]):
returns True when it should return False, since it is comparing a short (MS-DOS) path name with a long path name.
Should I use win32file.GetLongPathName to fix this problem, or do you know of a better solution?
