Loads of ways:
Good:
1) Public Property in Form2; set it from Form1
2) Event with argument in Form1; subscribe to event in Form2

Bad:
1) Public field in Form2; set it in Form1
2) Public field in Form1; grab it in Form2
3) Static field/property in either Form1 or Form2, set/grab in other.

There are others, but that covers most ways.

Solution 2

Create a static global class that contains a static string variable, and set it/get it from anywhere in the application. Of course, global static vars are generally frown upon by OOZ (object oriented zealots), but hey, it gets the job done, and it's efficient.

Create a Static object (single instance if you want) outside any form and later call it using that Static Variable.

This will ensure that you will access the same form object from anywhere.

In case of VB.NET, you might use Form1(name of the class) to implicitly access the Application object.
