python脚本读取和写入注册表的路径

我开发了一个python脚本，其中我有一个设置窗口，其中有选择安装软件的路径的选项。当单击设置窗口的确定按钮时，我想要将所有选定的路径写入注册表，并在设置窗口再次打开时读取相同的内容。我的代码如下所示。python脚本读取和写入注册表的路径

def OnOk(self, event): 
    data1=self.field1.GetValue() #path selected in setting window 
    aReg = ConnectRegistry(None,HKEY_LOCAL_MACHINE) 
    keyVal=OpenKey(aReg,r"SOFTWARE\my path to\Registry", 0,KEY_WRITE) 
    try: 
     SetValueEx(keyVal,"Log file",0,REG_SZ,data1) 
    except EnvironmentError: 
     pass 
    CloseKey(keyVal) 
    CloseKey(aReg)

我得到一个错误象下面这样：

Traceback (most recent call last): 
File "D:\PROJECT\project.py", line 305, in OnOk 
keyVal=OpenKey(aReg,r"SOFTWARE\my path to\Registry", 0,KEY_WRITE) 
WindowsError: [Error 5] Access is denied

而且从注册表中读取，保存的注册表在设定window.I显示了以下code.Though其工作尝试，但不满意我编程的方式。帮助我解决更好的解决方案

key = OpenKey(HKEY_CURRENT_USER, r'Software\my path to\Registry', 0, KEY_READ) 
    for i in range(4): 
     try: 
      n,v,t = EnumValue(key,i) 
      if i==0: 
       self.field2.SetValue(v) 
      elif i==1: 
       self.field3.SetValue(v) 
      elif i==2: 
       self.field4.SetValue(v) 
      elif i==3: 
       self.field1.SetValue(v) 
     except EnvironmentError:            
      pass 
CloseKey(key)

Python脚本从注册表中读取如下：

try: 
    root_key=OpenKey(HKEY_CURRENT_USER, r'SOFTWARE\my path to\Registry', 0, KEY_READ) 
    [Pathname,regtype]=(QueryValueEx(root_key,"Pathname")) 
    CloseKey(root_key) 
    if (""==Pathname): 
     raise WindowsError 
except WindowsError: 
    return [""]

Python脚本写入注册表是：

try: 
    keyval=r"SOFTWARE\my path to\Registry" 
    if not os.path.exists("keyval"): 
     key = CreateKey(HKEY_CURRENT_USER,keyval) 
    Registrykey= OpenKey(HKEY_CURRENT_USER, r"SOFTWARE\my path to\Registry", 0,KEY_WRITE) 
    SetValueEx(Registrykey,"Pathname",0,REG_SZ,Pathname) 
    CloseKey(Registrykey) 
    return True 
except WindowsError: 
    return False

希望它可以帮助你all.Cheers :)

看起来像您没有编辑注册表的权限。如果你是管理员，请运行此脚本，请在高架状态运行此脚本。

是的，我使用的是来宾用户，所以我没有得到它的权利。我将HKEY_LOCAL_MACHINE更改为HKEY_CURRENT_USER，现在工作正常。 – Aramanethota 2013-02-28 06:23:04

IS HKEY_CURRENT_USER是否适用于管理员和其他用户帐户？ – Aramanethota 2013-02-28 06:26:33

如果访客用户可以访问注册表中的密钥，那么Admin也是如此。 – 2013-02-28 06:30:20

与@Aramanethota相同，但使用pep8和func def可轻松使用。

REG_PATH = r"SOFTWARE\my_program\Settings" 

def set_reg(name, value): 
    try: 
     _winreg.CreateKey(_winreg.HKEY_CURRENT_USER, REG_PATH) 
     registry_key = _winreg.OpenKey(_winreg.HKEY_CURRENT_USER, REG_PATH, 0, 
             _winreg.KEY_WRITE) 
     _winreg.SetValueEx(registry_key, name, 0, _winreg.REG_SZ, value) 
     _winreg.CloseKey(registry_key) 
     return True 
    except WindowsError: 
     return False 

def get_reg(name): 
    try: 
     registry_key = _winreg.OpenKey(_winreg.HKEY_CURRENT_USER, REG_PATH, 0, 
             _winreg.KEY_READ) 
     value, regtype = _winreg.QueryValueEx(registry_key, name) 
     _winreg.CloseKey(registry_key) 
     return value 
    except WindowsError: 
     return None

来自https://stackoverflow.com/a/28365272/548792的Python脚本完成了所要求的内容等等。

下面是一些例子，假设它已被保存在当前路径中某处的文件setenv.py中。注意，在这个例子，你有你的电脑上没有管理权限，这样的变化仅适用于本地用户发生：

> REM ## Query env-var: 
> setenv.py PATH C:\foo 
!!!Cannot access HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment:PATH due to: [WinError 5] Access is denied 
!!!Cannot find HKEY_CURRENT_USER\Environment:PATH due to: [WinError 2] The system cannot find the file specified 

> REM ## Set env-var: 
> setenv.py PATH C:\foo 
!!!Cannot access HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment:PATH due to: [WinError 5] Access is denied 
---Updated HKEY_CURRENT_USER\Environment:PATH=C:\foo 

> REM ## Append env-var: 
> setenv.py +PATH D:\Bar 
!!!Cannot access HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment:PATH due to: [WinError 5] Access is denied 
---Updated HKEY_CURRENT_USER\Environment:PATH=C:\foo;D:\Bar 

> REM ## Delete env-var: 
> setenv.py -PATH 
!!!Cannot access HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment:PATH due to: [WinError 5] Access is denied 
---Deleted HKEY_CURRENT_USER\Environment:PATH

这是一类我写的（蟒蛇2）有能力在完成操作注册表时恢复状态。该类没有正确测试，因此它可能包含一些错误：
