  • Getting registry information using Python

    - by Willy
    I am trying to pull registry info from many servers and put them all into one txt file. I got the code working fine in a .bat file. I hear that there is a way simpler way to do this in Python. I am intrigued and delighted to hear this. Can anyone help finish my code: My working bat file: echo rfsqlcl01app >> foo.txt reg query "\\rfsqlcl01app\HKEY_LOCAL_MACHINE\SOFTWARE\Network Associates\TVD\Shared Components\On Access Scanner\McShield\Configuration\Default" >> foo.txt echo GLADGSQL01 >> foo.txt reg query "\\GLADGSQL01\HKEY_LOCAL_MACHINE\SOFTWARE\Network Associates\TVD\Shared Components\On Access Scanner\McShield\Configuration\Default" >> foo.txt echo GLADGWEB01 >> foo.txt reg query "\\GLADGWEB01\HKEY_LOCAL_MACHINE\SOFTWARE\Network Associates\TVD\Shared Components\On Access Scanner\McShield\Configuration\Default" >> foo.txt echo PAPERVISION >> foo.txt My python code structure: >>> server_list = open('server_test.txt', 'r') >>> for line in server_list: print r'reg query \\%s\blah\blah\blah' % line.strip() reg query \\foo\blah\blah\blah reg query \\moo\blah\blah\blah reg query \\boo\blah\blah\blah >>> server_list.close()

  • Python 2.6 - I can not write dwords greater than 0x7fffffff into registry using _winreg.SetValueEx()

    - by stasizke
    using regedit.exe I have manually created a key in registry called HKEY_CURRENT_USER/00_Just_a_Test_Key and created two dword values dword_test_1 and dword_test_2 I am trying to write some values into those two keys using following program import _winreg aReg = _winreg.ConnectRegistry(None,_winreg.HKEY_CURRENT_USER) aKey = _winreg.OpenKey(aReg, r"00_Just_a_Test_Key", 0, _winreg.KEY_WRITE) _winreg.SetValueEx(aKey,"dword_test_1",0, _winreg.REG_DWORD, 0x0edcba98) _winreg.SetValueEx(aKey,"dword_test_2",0, _winreg.REG_DWORD, 0xfedcba98) _winreg.CloseKey(aKey) _winreg.CloseKey(aReg) I can write into the first key, dword_test_1, but when I attempt to write into the second, I get following message Traceback (most recent call last): File "D:/src/registry/question.py", line 7, in <module> _winreg.SetValueEx(aKey,"dword_test_2",0, _winreg.REG_DWORD, 0xfedcba98) ValueError: Could not convert the data to the specified type. How do I write the second value 0xfedcba98, or any value greater than 0x7fffffff as a dword value? Originally I was writing script to switch the "My documents" icon on or off by writing "0xf0500174" to hide or "0xf0400174" to display the icon into [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\CLSID{450D8FBA-AD25-11D0-98A8-0800361B1103}\ShellFolder]

  • Listing serial (COM) ports on Windows?

    - by Eli Bendersky
    Hello, I'm looking for a robust way to list the available serial (COM) ports on a Windows machine. There's this post about using WMI, but I would like something less .NET specific - I want to get the list of ports in a Python or a C++ program, without .NET. I currently know of two other approaches: Reading the information in the HARDWARE\\DEVICEMAP\\SERIALCOMM registry key. This looks like a great option, but is it robust? I can't find a guarantee online or in MSDN that this registry cell indeed always holds the full list of available ports. Tryint to call CreateFile on COMN with N a number from 1 to something. This isn't good enough, because some COM ports aren't named COMN. For example, some virtual COM ports created are named CSNA0, CSNB0, and so on, so I wouldn't rely on this method. Any other methods/ideas/experience to share? Edit: by the way, here's a simple Python implementation of reading the port names from registry: import _winreg as winreg import itertools def enumerate_serial_ports(): """ Uses the Win32 registry to return a iterator of serial (COM) ports existing on this computer. """ path = 'HARDWARE\\DEVICEMAP\\SERIALCOMM' try: key = winreg.OpenKey(winreg.HKEY_LOCAL_MACHINE, path) except WindowsError: raise IterationError for i in itertools.count(): try: val = winreg.EnumValue(key, i) yield (str(val[1]), str(val[0])) except EnvironmentError: break
