回答（1）：

在窗体代码中添加如下代码即可
Option Explicit
Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hWnd As Long, ByVal nIndex As Long) As Long
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) 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 As Long = &H40000 '(恢复大小)
Private Const WS_MINIMIZEBOX As Long = &H20000 '(最小化)
Private Const WS_MAXIMIZEBOX As Long = &H10000 '(最大化)

Private Sub UserForm_Initialize()
Dim hWndForm As Long
Dim IStyle As Long
hWndForm = FindWindow("ThunderDFrame", Me.Caption)
IStyle = GetWindowLong(hWndForm, GWL_STYLE)
IStyle = IStyle Or WS_THICKFRAME '还原
IStyle = IStyle Or WS_MINIMIZEBOX '最小化
IStyle = IStyle Or WS_MAXIMIZEBOX '最大化
SetWindowLong hWndForm, GWL_STYLE, IStyle
End Sub

UserForm不支持运行时调整大小，VB支持，VBA不支持

回帖只是为了纠正楼上错误的观点
VBA的窗体的BorderStyle属性只有固定单边框样式但是可以利用编写代码来实现自由调整大小
Me.Width
Me.Height
设置窗体宽高
