This happens in your code only *after* function call, before function call pszPath may be not initialized. You don't have to create that buffer by transforming some meaningful string to null terminated string. See example on that page. It's a out buffer initially filled with garbage. So you don't need toStringz to create it. It's meaningless. > For example all registry functions... > RegCreateKeyW(IN HKEY hKey, IN LPCWSTR lpSubKey,... this is readonly string.

Can you mention at least one of them?
