Keterangan

Gaya batas formulir menentukan bagaimana tepi luar formulir muncul. Selain mengubah tampilan batas untuk formulir, gaya batas tertentu mencegah formulir berukuran. Misalnya, FormBorderStyle.FixedDialog gaya batas mengubah batas formulir ke kotak dialog dan mencegah formulir diubah ukurannya. Gaya batas juga dapat memengaruhi ukuran atau ketersediaan bagian bilah keterangan formulir.
