To create a dimension between a panel and a form in VB.NET, you can use the Anchor property and set it accordingly. Here's how you can achieve it:
Place a Panel control on your form at the desired location.
Adjust the size and position of the Panel control as needed.
Set the Anchor property of the Panel control to Top, Bottom, Left, and Right. This ensures that the panel resizes with the form and maintains a dimension between them.
