What gets selected, when the project is run?

@RodDog, your way will make it "look normal" but all controls are disabled, you will need code to enable them.
I think the OP wants no control gets focus when open the form but they must be enabled as normal and ready to be clicked.
By default, as LaVolpe said, the first enabled control (in tab order), if any, will receive focus when the form open, if no enabled control the form will receive focus.

That code would just be

Frame1.Enabled = True
