Start filtering filesystem operations.
void __fastcall StartFilter();
This method attaches the filter, causing the component's system driver to start filtering filesystem operations according to the filter rules currently present. Rules can be added and removed both before and after this method is called, so long as the Initialize method is called before doing anything else.
This method can fail for a number of reasons, including (but not limited to) the following:
- If the component's system driver has not been properly installed, or is awaiting a system reboot (as indicated by the return value of Install), this method fails with an ERROR_FILE_NOT_FOUND (2) error code.
- If the Initialize method has not been called yet, this method fails with an ERROR_NOT_READY (21) error code.
- If the filter is already Active, this method fails with an ERROR_CONNECTION_ACTIVE (1230) error code.
