In the 6.0 version, the code allowed all the properties of a created form, such as a textbox/label/etc. to be passed to a subroutine by sending the form name. Then in the subroutine, all the attributes/properties are accessible. How is this done in VB.NET I have tried to use the same idea and it will not work. Thanks!
