AXAPTA - Security check with X++ code

Sometimes we need security check with code (Display method etc...):



    SecurityKeySet securityKeys = new SecurityKeySet();
    ;
    securityKeys.loadUserRights(curuserid());
   if (securityKeys.access(securitykeynum("KRC_CrossCompany")) ==  AccessType::NoAccess)
   chkCrsCompany.value(NoYes::No);
