Hi, is there anything already available in the SDK, that allows one to read/write windows registry values?
If not, is there a preferred way of doing so?

The typical C++ code for this is:
RegOpenKeyEx(), RegGetValue(), RegSetKeyValue(), and don't forget to RegCloseKey()

But please don't do this in plugins for sale!!!!
I need to format my HD at least 4 times a year because of people dumping tons of garbage in my registry.

Create a folder in your plugin's folder structure to hold any persistent data. So it get's deleted automatically if the user deletes your plugin.
Please...Don't do it.

In the SDK, you have:

ReadRegInfo() and WriteRegInfo()
SetWorldContainer() and GetWorldContainer()

These might be more useful alternatives to using the Windows registry.

Don't worry, it's not used for my plugins! I strongly stick to Maxons guidelines.

It's need to detect an external aplication and optionally set its parameters.

If you're interested, here's the first prototype I came up with:

  
inline std::string QueryRegistryValue(HKEY hKey, const LPCWSTR subKey, const char* keyName)   
{   
     HKEY hKeyResult;   
     WCHAR buffer[512];   
     DWORD buffer_size = SIZEOF(buffer);   
  
     if (RegOpenKeyExW(hKey, reinterpret_cast<LPCWSTR>(subKey), 0, KEY_READ, &hKeyResult;) == ERROR_SUCCESS)   
     {   
          if (RegQueryValueExA(hKeyResult, keyName, nullptr, nullptr, reinterpret_cast<LPBYTE>(buffer), &buffer;_size) == ERROR_SUCCESS)   
          {   
               RegCloseKey(hKeyResult);   
               return std::string(reinterpret_cast<char*>(buffer));   
          }   
          RegCloseKey(hKeyResult);   
     }   
  
     return std::string();   
}
