How to pass realtime data on multiple window form

hi, i have a multiple window forms (8 windows forms) application in C# language, but am having problem of passing data between the forms in realtime,i used Delegates for all the child forms which allows me to pass data from parent form but i have to open all the 8 window forms else i get a compiler error. i.e upon start of my application i have to open all the 8 windows in other for the application to pass data effectively.

Brief Description of my Project

my application accepts realtime data (8 time chaging data from a hardware interfaced to the serialport) and sends it to my c# application which displays the 8 variables in 8 different textboxes on the main form also each variable has its own window form acessed via a button click, i have used delegates to pass data from the parent form(Main) to all the eight child forms but the problem is that all the forms has to be open before my application will pass data to it otherwise it throws an exception(compiler error) when i try to debug.how can i solve this problem.
thanks

You should have one or more classes separate from the form classes for the data and the forms should be used to show the data. Your class that gets the data can and should notify the open forms when the data has changed; the data class could have an event (a delegate) that is called when the data changes and the forms could add themselves to the list of event handlers for the event. You would need to remove a form from the list of handlers when the form closes.
