Extra activation data

When customers activate your software, or if they use verified trials, you can pass along extra information to the activation servers that will help you identify the customer. This extra data will be visible to you on the product key page next to the other information like the IP address and the date activated:

Extra activation data

In this example you can see many activations behind the same IP address. The way you can tell activations apart is by the extra data. In this example the computer user's name is used. However you can use anything you want for extra data.

How to pass extra data to LimeLM

Passing extra activation data to the servers is as simple as calling the TA_Activate() function. In C++ passing extra data would look like this:

opts.nLength = sizeof(ACTIVATE_OPTIONS);
opts.sExtraData = "Here's some extra data";

HRESULT hr = TA_Activate(taHandle, &opts);

For all other languages (C#, Java, etc.) the Activate() function is overridden to allow a string "extra data" parameter. So, in C# passing extra data would look like this:

ta.Activate("Here's some extra data");

It's similar for the other language integrations of TurboActivate. If you're using the TurboActivate wizard to activate a customer then you can pass extra data to the wizard by using the "--extradata" commandline option:

TurboActivate.exe --extradata="Here's some extra data"

Here's an example of passing extra data with verified trials in C/C++:

uint32_t trialFlags = TA_VERIFIED_TRIAL | TA_SYSTEM;
HRESULT hr = TA_UseTrial(taHandle, trialFlags, "Here's some extra data");

And in C# this same functionality would look like this:

TA_Flags trialFlags = TA_Flags.TA_SYSTEM | TA_Flags.TA_VERIFIED_TRIAL;
ta.UseTrial(trialFlags, "Here's some extra data");


The maximum size of the extra data is 255 UTF-8 characters.

How the extra data is used

The extra data you pass to LimeLM is for your use only. It's to help you distinguish between multiple activations. The extra data is not used in TurboActivate's "fingerprinting" algorithm.
