excel VBA 窗体 如何禁用窗体关闭按钮

我们前面讲了怎样去除 VBA 窗体的关闭按钮，其实个人感觉没有这个关闭按钮会使整个窗体感觉有点怪，但有时候又想让他不可用，变得不可点击，那该怎么实现呢？ 好，我们马上就来试一试看看。

操作如下：
◾在Excel 的VBE窗口中插入一个用户窗体，将其命名为 frmNotEnabledCloseIcon。然后再添加一个模块。在窗体和模块中添加后面所列代码。
◾在工作薄中的工作表中添加一窗体按钮控件，指定其设置宏 ShowNotEnabledCloseIconForm, 其供示范之用.

具体代码：

"frmNotEnabledCloseIcon" 窗体代码

Option Explicit

End Sub
'**************************************

Private Sub UserForm_Initialize()
'查找窗口句柄
FHwnd = FindWindow("ThunderDFrame", Me.Caption)
'取得窗体系统菜单
hMenu = GetSystemMenu(FHwnd, 0)
'删除系统菜单中关闭菜单
DeleteMenu hMenu, SC_CLOSE, MF_BYCOMMAND
'重绘窗体标题栏
DrawMenuBar FHwnd
End Sub

"mdNotEnabledCloseIcon" 模块代码

Option Explicit'
此过程为工作表内按钮调用
Sub ShowNotEnabledCloseIconForm()
frmNotEnabledCloseIcon.Show
End Sub
