I made a question that looked like this before and people didn't understand. I'll try to be more concise and will use a comparison with Ajax used in web applications.
I have the main form. There I have one button that will extract data from a field and send to a second form, a window that will pop up and display the data in a more organized way (A TListBox).
I would like to know if there is a way to on SecondForm.Show to send this data as parameters, like SecondForm.Show(data).
The comparison to Ajax is that when you make an Ajax Call from a html page to the server, you send encapsulated data, the server receives it and works with it.
I want my main form to send the data, the second form to receive the data and use it.
Is it possible? How?
Decide in what form to send the data from Main to SecondFrom. For instance in a TStringList. Fill the striglist on the mainform, use it as parameter in SecondForm.Show.
