HRESULT ILockBytes_Read([in]VARIANT buffer, [out, retval] VARIANT* lockbytes);
returns a lockbytes interface from a buffer (byte array). Used with automation languages such as VBScript.

HRESULT ILockBytes_Delete([in]VARIANT lockbytes);
deletes a lockbytes interface wrapped inside a VARIANT. Used with automation languages such as VBScript.

HRESULT WriteFile([in]BSTR filename, [in]VARIANT buffer);
