winreg

the windows registry may contain keys whose names with embedded nulls when i call _winreg.OpenKey(key, subkey_string_with_embbeded_null) i get the following error: TypeError: OpenKey() argument 2 must be string without null bytes or None, not str Q1: is the meaning of the error that python _winreg module has a limitation that it cannot open keys whose names have embbeded nulls? Q2: how do i get around this limitation? Q1: right. Q2: download and install win32all . 来源： https://stackoverflow.com/questions/2384064/python-winreg-problem

I'm having some problems accessing the Windows 7 Registry with the _winreg.QueryValueEx function in the Python 2.7.3 _winreg module. I am running the python process as Administrator , and can create new keys and values like this: import _winreg as wreg key = wreg.CreateKey(wreg.HKEY_LOCAL_MACHINE, "Software\\TestCompany\\TestProject") # Create new subkey wreg.SetValue(key, 'NewSubkey', wreg.REG_SZ, 'testsubkey') print wreg.QueryValue(key, 'NewSubKey') # prints 'testsubkey' # Create new value wreg.SetValueEx(key, 'ValueName', 0, wreg.REG_SZ, 'testvalue') print wreg.QueryValueEx(key,'ValueName')
