VBA的窗体其实就是一个Dialog(对话框窗体)，缺少完整窗体的许多元素，窗体标题栏上的图标就是其中之一，有时我们自己需要美化一下它，使用代码来为它添加窗体图标(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frmIcon。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btnShowfrmIcon_Click。其供示范之用。

具体代码：

"mdIcon"模块代码

Sub btnShowfrmIcon_Click()
frmIcon.Show
End Sub

"frmIcon" 窗体代码
