I have tried for like 3 hours now to change the text of label, but I haven't succeeded.

I have tried numerous ways, Invoking, Defining, Subs etc. etc.

I have 2 forms. Form1 and Form2. Form2 is opened by Form1 via ShowDialog. When click a button on Form2 I to change the text of the label on Form1. Form2 also gets closed by that button.

And what I've found out, the text gets changed, but It doesn't appear. The control don't want to display it too me
