VBA 窗体之去除窗体关闭按钮

JT_man 2014-09-04

VBA 的窗体缺少一般窗体的很多属性，不想许多语言窗体那样可以自由的设置窗体的样式，就连其默认的关闭按钮也不能设置为不显示，一般的处理方法是在窗体的关闭事件中添加代码来阻止窗体的关闭。那还不如就直接运用代码来把他去除掉(如图)。

操作如下：

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

具体代码：

"mdClose" 模块代码

Sub btnShowfrmMaxMin_Click()
    frmNoCloseIcon.Show
End Sub

"frmNoCloseIcon" 窗体代码
