Remarks

You can use the CSettingsStoreSP class to redirect all MFC registry operations to other locations, such as an XML file or a database. To do this, follow these steps:

1. Create a class (such as CMyStore) and derive it from CSettingsStore.

2. Use DECLARE_DYNCREATE and IMPLEMENT_DYNCREATE macros with your custom CSettingsStore class to enable dynamic creation.

3. Override the virtual functions and implement the Read and Write functions in your custom class. Implement any other functionality to read and write data to your desired location.

4. In your application, call CSettingsStoreSP::SetRuntimeClass and pass in a pointer to the CRuntimeClass Structure obtained from your class.

Whenever the framework would typically access the registry, it will now dynamically instantiate your custom class and use it to read or write data.

CSettingsStoreSP::SetRuntimeClass uses a global static variable. Therefore, only one custom store is available at a time.
