Hidden script
When QlikView script is being executed, the results of the actions are written to the
Script Execution Progress window (and, if enabled, the log file). While this is a very useful feature to see what happened during reload, sometimes you do not want certain things (for example, login credentials) to be visible to everyone. In fact, sometimes you do not even want all developers to have access to the entire script. This is where the hidden script comes into play.
The hidden script is a password protected part of the script. It is always the left-most tab (and cannot be moved), so it is executed before the regular script is reloaded. Anything that is executed within the hidden script is not written to the log.
Note
Logging for the hidden script can be turned on by checking the Show Progress for Hidden Script checkbox on the Security tab of the Document Properties. Note that this will allow others to use the debugger to step through the hidden code. Since this defeats a main point...
