感谢我的朋友们

谢谢大家！

今天我读到了一位朋友sudianbo84的邮件，照抄如下：

Dear Mr solol,
I am sorry to send this email to bother you due to my stupidity,however ,I really need your help . 
Imitating the  main() method provided by yours JNIRegistry Package  , I wrote a program to modify 
the Internet Explore's settings in the windows' Registry ; but with something  wrong when I run my 
program,I hope you can give me some  help or advices! the following is the hints when my program runs
 
"com.ice.jni.registry.RegistryException: Registry API Error 5, 'access denied' - 'RegSetValueEx()'
  at com.ice.jni.registry.RegistryKey.setValue(Native Method)
  at org.solol.test.ssss.main(ssss.java:29)
com.ice.jni.registry.NoSuchValueException: RegQueryValueEx(), value='ProxyServer'
  at com.ice.jni.registry.RegistryKey.getStringValue(Native Method)
  at org.solol.test.ssss.main(ssss.java:47)
Press any key to continue..."
 
And this Is my program list:(I hope you can give me some  help or advices! )
 
package org.solol.test;
import com.ice.jni.registry.NoSuchKeyException;
import com.ice.jni.registry.RegStringValue;
import com.ice.jni.registry.RegDWordValue;
import com.ice.jni.registry.Registry;
import com.ice.jni.registry.RegistryException;
import com.ice.jni.registry.RegistryKey;
import com.ice.jni.registry.RegistryValue;
/**

public class ssss {
  /**
   * @param args
   */
  public static void main(String[] args) {
    try {
      RegistryKey IEsetting = Registry.HKEY_CURRENT_USER.openSubKey("Software").openSubKey("Microsoft").openSubKey("Windows").openSubKey("CurrentVersion").openSubKey("Internet Settings");
      IEsetting.setValue("ProxyServer", new RegStringValue(IEsetting,"ProxyServer","127.0.0.1:8080"));
      IEsetting.setValue(new RegDWordValue(IEsetting,"ProxyEnable",	RegistryValue.REG_DWORD,1)); 
      
      IEsetting.closeKey();
    } catch (NoSuchKeyException e) {
      e.printStackTrace();
    } catch (RegistryException e) {
      e.printStackTrace();
    }

    try {
      RegistryKey IEsetting = Registry.HKEY_CURRENT_USER.openSubKey("Software").openSubKey("Microsoft").openSubKey("Windows").openSubKey("CurrentVersion").openSubKey("Internet Settings");
      //RegistryKey IEsetting = software.openSubKey("SubKeyName");
      RegistryValue proxyenable = IEsetting.getValue("ProxyEnable");
      String proxyserver = IEsetting.getStringValue("ProxyServer");
      System.out.println(proxyenable.toString());
      System.out.println(proxyserver);
      IEsetting.closeKey();
    } catch (NoSuchKeyException e) {
      e.printStackTrace();
    } catch (RegistryException e) {
      e.printStackTrace();
    }   
  }
}	

这是由于我在文章用Java操作Windows注册表中犯了一个错误。

出错内容为：

  RegistryKey openSubKey(java.lang.String subkey) 打开该key的subkey，具有写权限。 

应该为：

  RegistryKey openSubKey(java.lang.String subkey) 打开该key的subkey，具有读权限。 

我已经对文章进行了更新。

sudianbo84朋友要解决你的问题可以使用下面的代码：

  RegistryKey currentVersion = Registry.HKEY_CURRENT_USER.openSubKey("Software").openSubKey("Microsoft").openSubKey("Windows").openSubKey("CurrentVersion");
  RegistryKey inetSetting = currentVersion.openSubKey("Internet Settings",RegistryKey.ACCESS_WRITE);
  inetSetting.setValue(new RegStringValue(inetSetting, "ProxyServer", "127.0.0.1:8080"));
  inetSetting.setValue(new RegDWordValue(inetSetting, "ProxyEnable",RegistryValue.REG_DWORD, 1));

再次感谢大家！谢谢！
