How can I detect Form Open event and Import data event ?

[Former Community Member]

We are using Adobe Designer 7 and Adobe Reader 7.0.5. When we open a Form, Initialize event is being called. Similarly when we Import any data, initialize event is being called. At the Initialize event, I want to know whether it is caused by Opening the Form (or) Importing the data. Please respond as we were completely stuck up with this issue.
