If the Write-Random check box is clear, you can click Browse to
copy the contents of a file into the raw data feature. You can specify
Offset and Length, in bytes, for the file contents you want to copy. By
default, Offset is 0 and Length is 2032, indicating that only first 2032
bytes of data is copied. Alternatively. you can also click the Hex-ASCII
converter to browse the file.
6. Specify a write password if you want to write the feature value using
the SFNTWriteRawData API function. The option will be disabled if
you have selected the Read-only option.
7. Selecting the Add instances later check box will allow you to add
new feature instances later in the License Manager screen. This
option helps in modifying the "licensing values" without modifying
the "licensing implementation" in the application/code.
The option will be disabled if you have selected the Write-Once and/
or Write-random option.
8. If you selected the check box described in step 7, specify the maximum
size. It has to be greater than the existing feature size and less than
2032 raw data characters. The overridden values will never exceed
the maximum limit set.
9. Provide a name for this feature (necessary).
10. The constant name will be automatically generated. However, you
may modify it, if needed.
11. You may optionally provide comments. When done, click OK.
4.The maximum length is 2032 bytes for SHK XM keys; and 888 bytes for non-XM keys.
