Private Declare Function DrawMenuBar Lib "user32" (ByVal hwnd As Long) As Long
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 Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Const GWL_STYLE As Long = (-16)
Private Const WS_CAPTION As Long = &HC00000

Private Sub UserForm_Initialize()
   Dim AppV!, hwnd&, IStyle& 
   
   AppV = Application.Version                           '判断Excel版本
   If Val(AppV) &lt; 9 Then
      hwnd = FindWindow("ThunderXFrame", Me.Caption)    '获得ThunderRTMain类的隐藏窗口的句柄
   Else
      hwnd = FindWindow("ThunderDFrame", Me.Caption)
   End If
   
   IStyle = GetWindowLong(hwnd, GWL_STYLE)              '从指定窗口的结构中取得信息, GWL_STYLE：窗口样式，即取得窗口样式信息
   IStyle = IStyle And Not WS_CAPTION
   SetWindowLong hwnd, GWL_STYLE, IStyle
   DrawMenuBar hwnd   
End Sub

其中的 IStyle = IStyle And Not WS_CAPTION是什么意思，谢谢大家！

[解决办法]
将 IStyle 和 &HC00000 的按位非值进行按位与.
[解决办法]
简单的讲就是把Window Style里面的WS_CAPTION拿掉。

语法 IStyle = IStyle And Not WS_CAP
