Thanks for the reply! I have attached a zip with a sample project which (I think) illustrates my problem. If you have some time to spare, could you take a look at it? Thanks and sorry for my pretty rookie problems... http://www.djnokturnal.com/downloads/TextBoxes.zip[^]

..\..\..\SecondClass.cs(12): 'System.Windows.Forms.Form' does not contain a definition for 'textFromSecondClass' That is what I get when I try to use your code. I guess I have some reading to do. Thanks anyway.
