Hi all,
I'm having a problem when opening and enumerating a network resource
many times. For example:
i = 0
while i < 10000:
handle =
win32wnet.WNetOpenEnum(win32netcon.RESOURCE_CONNECTED,
win32netcon.RESOURCETYPE_ANY, 0, None)
partial_nr_list = win32wnet.WNetEnumResource(handle)
while partial_nr_list:
partial_nr_list = win32wnet.WNetEnumResource(handle)
win32wnet.WNetCloseEnum(handle)
i += 1
This eventually fails with:
Traceback (most recent call last):
File "C:\qtest.py", line 17, in <module>
partial_nr_list = win32wnet.WNetEnumResource(handle)
MemoryError: VirtualAlloc error in WNetEnumResource
I took a look at the source for win32wnet.WNetEnumResource and it
seems to be doing the correct thing in terms of memory. My application
isn't doing the above exactly, however it does open/enumerate many
times. Any ideas on what may be going on?
Thanks,
Gustavo
