I'm designing a program that will display share quotes and share information. Currently I have my main form and 2 additional forms (frmStockQuotes and frmStockInfo). The main form, every 30 seconds will go off to a website and get the share quotes and information for all the stocks listed in frmStockQuotes and frmStockInfo.

My issue/question is, how to I pass all the stock codes from frmStockQuotes and/or frmStockInfo to my main form and once received from both (or one if only one of the forms are open) go off and get all the info from the web? Once all the info is retrieved how would I pass the info back to each form?

Once I have this example complete I will be adding additional forms which will do the same thing so I could have 10 forms open that all need to send their stock lists back to the main form before the share info is retrieved.

Any help would be appreciated
