How to pass a password to the ebook with the command line?

• Can I pass a password from command line?
  If the password is incorrect, the ebook should:
  1) Show a page containing purchase information about my product.
  2) Block access to my presentation at all.
  

With security profiles and a single HEScript custom function, you can achieve this goal.

First you need to write the HEScript function that checks your password:

• Open your HTML Executable project and select the "Behavior & Scripting" tab.Then double-click on the "UserMain" script to open the script editor as shown on the figure.
• In the script editor, insert a new script function called "CheckPassword" (you can give it another name but remember it in that case) and paste the script available below; click on Save. The editor is closed.

Be sure to change the MYPASSWORD text to the password you want. In this script version, passwords will be case-sensitive.

Secondly we need to modify the Default security profile; go to the Security tab and select Security Profiles. Highlight "Profile: Default"; click on Add and choose Add New Condition.
The "Add a condition" dialog box is shown; choose "If the following boolean script function returns true". HTML Executable asks you to select the boolean function: it's the "CheckPassword" one you created previously. Close all the dialog boxes.

Finally, select the new condition and click on "Configure". Select the "Locking Pages" tab and enable "Pages are locked and cannot be viewed".
If you want to display a "registration page", just select it using the "Select" button.

Compile your publication and that's all.

Note: it is also possible to a new security profile that will only forbid a given set of HTML pages, and much more.
