GetLicenseKey()

joadwe · July 28, 2021, 1:59pm

Using the C library LexActivator.h from MATLAB what input arguments are needed to obtain the license key?

Currently using:
sSharedLibrary = ‘LexActivator’;
loadlibrary(sSharedLibrary,@LexActivatorPrototype)
[valid] = calllib(sSharedLibrary,‘IsLicenseGenuine’)
[output] = calllib(sSharedLibrary,‘GetLicenseKey’)

and receiving the error:
No method with matching signature for the ‘GetLicenseKey’ input. The ‘IsLicenseGenuine’ is functioning correctly and returning 0.

Hi Joshua,

Please refer to the following, your case is similar:

github.com

cryptlex/lexactivator-matlab/blob/master/examples/Sample.m#L40


status = calllib(sSharedLibrary,'SetAppVersion',toString(sAppVersion));
if status ~= 0
    fprintf('Error Code: %.0f\n',status)
    return
end
% Calls function to check if license is activated
status = calllib(sSharedLibrary,'IsLicenseGenuine');
if status == 0
    fprintf('License is genuinely activated!\n')
    % [status, metadataKey, metadataValue] = calllib(sSharedLibrary,'GetLicenseMetadata', toString('feature1'), blanks(256),256 );
    % disp(metadataValue);
elseif status == 20
    fprintf('License is genuinely activated but has expired!\n')
elseif status == 21
    fprintf('License is genuinely activated but has been suspended!\n')
elseif status == 22
    fprintf('License is genuinely activated but grace period is over!\n')
else
    % Calls function to check if license is activated
    trialStatus = calllib(sSharedLibrary,'IsTrialGenuine');

Great, that worked. Thanks!
