Since LM-X requires by default that the version number in the license file be greater than or equal to the version number specified in the application, the license file will determine how long users can continue to use new updates of the software. If a the software version has a date newer than is later than the date specified in the license file, that version of the software will not work without an updated license.

...

1. , as shown in the following example, which specifies the license file will work until 2014, October 3:

...

1. which specifies the compile date 2014, January 1:
   
   

   Code Block
   language cpp

...

1. 01; int nDay =

...

1. 01; int nMajor = nYear; int nMinor = nMonth * 10 + nDay; LMX_Checkout(LmxHandle, "F1", nMajor, nMinor, 1);

...

...

1. in the following example,  LMX_Checkout will return an error, and the user will require a new license file to run the new version of the software.  
   
   

   Code Block

   int nYear = 2014; int nMonth = 12; int nDay =

...

1. 30; int nMajor = nYear; int nMinor = nMonth * 10 + nDay; LMX_Checkout(LmxHandle, "F1", nMajor, nMinor, 1);
