在 VBE 编辑器中，我们能看到很多的小标题栏窗体，这就是工具栏窗体，其实我们通过对VBA用户窗体的定制，也可以使VBA的用户窗体成为工具栏式窗体。本文就是运用API函数来定制 Office 中的用户窗体，使其成为工具栏窗体。

点击链接从百度网盘下载操作如下：◾在Excel 的VBE窗口中插入一个用户窗体，将其命名为 frmTools。在用户窗体中添加两个按钮，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 btnToolsForm_Click。其供示范之用.具体代码：
"ModToolsForm" 模块代码
Sub btnToolsForm_Click()frmTools.ShowEnd Sub
"frmTools" 窗体代码
