Changing the window style seems to work, but may need more testing.

Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA"
( _
ByVal hwnd As Long, ByVal nIndex As Long) As Long

Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA"
( _
ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As
Long

Private Const GWL_STYLE = (-16)
Private Const WS_THICKFRAME = &H40000

Private Sub MDIForm_Load()
Dim dwStyle As Long
dwStyle = GetWindowLong(Me.hwnd, GWL_STYLE)
SetWindowLong Me.hwnd, GWL_STYLE, dwStyle And (Not WS_THICKFRAME)
End Sub

Was I wrong ?

The OP wasn't clear, and I assumed the child form was the intent.

I just did look in VB, and the child forms do have a border style
property but the parent does not.

Well, the subject line said MDI form, so I took it verbatim. Add to that the
fact that there isn't much point in asking about child forms since, as you
say, they DO have the BorderStyle property, and I'd say it's likely he was
asking about true MDIForm objects.

It didn't even occur to me that the OP may have been asking about the
parent MDI form. It doesn't make any sense ....not to me anyway.
