Bernard,
I just always leave the BorderStyle set to 3 on the property sheet and set it to 2 in the Form.Init() that way the form is more easily worked with in the designer.
>Set the "BorderStyle" property to Fixed Single. Now no one even you can resize the form. If you need to resize the form in the development environment to make any changes you will have to change this property back to 3 - Sizable and later change it back to 1- Fixed Single
