How to bind OCX to NF serialno.

r_schueler

Hi everybody,

I'm planning to create an OCX for Navision Financials 2.01. I want this OCX to run only if the serialno of the NF Server matches the one hidden in the OCX (for copy protection and licence reasons). The problem is how to get the server serialno
from within the OCX. Could it be done using C/Front and
is a special NF licence needed for using C/Front ?

Best regards

I don't think it's possible to read the serialno of the license-file on the server. In C/FRONT there is a function CHECKLICENSEFILE but this checks the permissions of a specified object.

You can read the fin.flf on the client-side, and check for the serialno (using Visual Basic), but you can't read the fin.flf on the server. There is no reason to give read-access to the directory on the server where the server.exe and fin.flf resides.

Use C/Front to have a look at system table 2000000040 licence information. This has two fields, line no. & text. You should then be able to access the licence in use by the server and look for the line with the serial number.

Haven't tried it with C/Front but it works from C/AL.

How would this be affected by new Navision licences?
Upgrades etc:

Would you have to recode your OCX?

Better to create licence encription within the OCX code for registering your OCX!

I checked several Navision licences: when adding granules to an existing license or when upgrading from eg. NF 1.10 to NF 2.00, the serial number was always the same.
