我无法制作此代码,我找到了适合我的工作。
现在:它在注册表中添加2个DWORD值作为Interface文件夹(注册表项)。
Desired :我希望它将这2个DWORD值添加到Interface注册表项(文件夹)的所有子项(子文件夹)中。
我有这个伪代码:
我会继续尝试对此进行排序,但也许有人可以提供帮助吗?

答案 0 :(得分:1)
这是一个没有任何额外内容的最基本的例子:
// open desired key whose subkeys shall be enumerated
HKEY hKey={0};
LPCTSTR path=TEXT("SYSTEM\\CurrentControlSet\\services\\Tcpip\\Parameters\\Interfaces");
if(RegOpenKeyEx(HKEY_LOCAL_MACHINE,path,0,KEY_ENUMERATE_SUB_KEYS,&hKey) != ERROR_SUCCESS)
return; // failed to open
DWORD index=0; // enumeration index
TCHAR keyName[256]={0}; // buffer to store enumerated subkey name
DWORD keyLen=256; // buffer length / number of TCHARs copied to keyName
// enumerate subkey names of hKey, result stored in keyName, keyLen set to strlen(keyName)
while(RegEnumKeyEx(hKey,index++,keyName,&keyLen,0,0,0,0) == ERROR_SUCCESS) {
keyLen=256; // reset buffer length (RegEnumKeyEx changes this value)
// open the subkey and set the desired value(s)
HKEY hSubKey={0};
if(RegOpenKeyEx(hKey,keyName,0,KEY_SET_VALUE,&hSubKey) == ERROR_SUCCESS) {
// set desired value(s):
DWORD myValue = 0xCAFEBABE;
//RegSetValueEx(hSubKey,TEXT("MyValueName"),0,REG_DWORD,(LPBYTE)&myValue,sizeof(DWORD));
RegCloseKey(hSubKey); // close sub key
}
// else: failed to open subkey
}
// RegEnumKeyEx either returns ERROR_SUCCESS, ERROR_NO_MORE_ITEMS, or a system error code
RegCloseKey(hKey); // close key
请注意,此示例不评估错误代码。它只是演示了枚举子键和设置值的过程。 RegOpenKeyEx访问权限设置为执行此任务所需的最小值(将它们设置为您希望对打开的键执行的操作)。 while循环与ERROR_NO_MORE_ITEMS(一旦没有枚举的子键)或实际错误没有区别。 RegSetValueEx被注释掉以确保安全,并忽略其返回值。
