How would it be possible to check if a subKey exist in the Classes root in Registry Editor. My attemt is like follows but my compiler doesn´t like it.

'Microsoft::Win32::RegistryKey' : class does not have a copy-constructor
no conversion from 'nullptr' to 'Microsoft::Win32::RegistryKey'

C++ Syntax (Toggle Plain Text)

Microsoft::Win32::RegistryKey subKey1 = Microsoft::Win32::Registry::ClassesRoot->OpenSubKey("one\\two");
 
	 if( subKey1 != nullptr ) //Exists ?
	 {
                         //do something
	 }

Microsoft::Win32::RegistryKey subKey1 = Microsoft::Win32::Registry::ClassesRoot->OpenSubKey("one\\two"); if( subKey1 != nullptr ) //Exists ? { //do something }
