Return value

C++

This method can return one of the following:

• S_OK, indicating that the operation succeeded.
• An error code, indicating that the operation failed. In this case, the [out] parameter returned is a null object.

VB

This method returns a reference to the FPCCacheDrive object added if the call is successful. Otherwise, an error is raised that can be intercepted by using an error handler.

Remarks

When you add a drive to the FPCCacheDrives collection, and have saved changes by using the Save method, the Microsoft Firewall service must be restarted for your change to take effect. You can use the RestartServices method of the FPCArray object (IFPCArray interface in C++) to stop and restart the Firewall service.
