Store data in the license file
Contents
This feature allows storing encrypted data in the license file. The license file acts like a small database.
The data area could be used to store:
| • | Program configuration parameters |
| • | Usage of the application - like number of program starts or last online validation |
| • | Additional customer information |
| • | Other custom values you do not want to save in a configuration file or a database |
It works in the way that you use an ID and assign a text to this ID, e.g. ID = LastOnlineValidation, Text = 09/09/201.
There is a complete set of API commands to read and modify the data.
Save a value
Command SetConfig. If the ID already exists, the existing value is updated with the new value.
Read a value
Command GetConfig
Delete a value
Command DeleteConfig
Check if a value exists
Command ExistsConfig
Preconfigure values in the project template
Values can be preconfigured in the project template. They are added automatically to the license file
Example
<Configs>
<Config name="CustomerID" visible="no">D83726</Config>
<Config name="BasicConfiguration" visible="yes">This is a text</Config>
</Configs>
Do not store large data e.g. MIME-encoded binary data like images or movies as this would significantly slow down the access to the license file.
