Sorry to anyone who read this post, but in case it's useful to anyone:
Further experiments reveal that while a tuple comes back if you read a
multi-line string, you set the value using a list (not a tuple). That's
sensible and I don't know why this didn't occur to me before I posted.
Thanks

Subject: Writing to REG_MULTI_SZ windows registry keys
Hello. I'm looking for any information I can get about writing values to
keys in the Windows registry when the value type is a multi-string (ie.
REG_MULTI_SZ). When I get the value of a multi-string value using winreg
functions, I get a tuple with tuple[0] being a list, and tuple[1] a number.
If I try to write such a tuple back into a multi-string value, I get the
following exception:
ValueError: Could not convert the data to the specified type.
I haven't been able to find any documents, postings, etc. that deal with
this specifically. My test code is listed below. If any tips can be
offered, they will be much appreciated!
from _winreg import *
import sys
#get the current value of the PendingFileRena meOperations key
def getCurrentValue ():
aReg = ConnectRegistry (
None,
HKEY_LOCAL_MACH INE)
aKey = OpenKey(aReg, r"SYSTEM\Curren tControlSet\Con trol\Session
Manager")
value = QueryValueEx(aK ey, "PendingFileRen ameOperations")
CloseKey(aKey)
return value
#set the value of a test REG_MULTI_SZ key (this key already exists")
def setNewValue(val ue):
aReg = ConnectRegistry (
None,
HKEY_LOCAL_MACH INE)
aKey = OpenKey(aReg, r"SOFTWARE\PRN_ TEST", 0, KEY_WRITE)
SetValueEx(
aKey,
"PendingFileRen ameOperations",
0,
REG_MULTI_SZ,
value
)
CloseKey(aKey)
#the name of some file I want to add to the list
renamedTarget = r"C:\some_file_ i_want_to_delet e.txt"
tuple = getCurrentValue ()
print tuple
list = tuple[0]
list.append(uni code(renamedTar get))
newtuple = (list, tuple[1])
setNewValue(tup le)
