Invalid drive is specified, or drive is unavailable. |
See the "Error number" column if you are upgrading Visual Basic 6.0 applications that use unstructured error handling. (You can compare the error number against the Number Property (Err Object).) However, when possible, you should consider replacing such error control with Structured Exception Handling Overview for Visual Basic.

The ChDrive function requires unmanaged-code permission, which may affect its execution in partial-trust situations. For more information, see SecurityPermission Class and Code Access Permissions.
