在Userform上显示Excel工作簿

Question

目标:正如标题所示,我们如何在不使用任何第三方控件的情况下在userform上显示工作簿.

通过Display,我的意思是显示它在一个窗体,其中用户可以选择一个工作表,并查看工作表的内容.

这篇文章试图自我回答这个问题.

Answer 1

我将在下面演示的方法不会使用任何第三方控件.实际上它会在图像控件中显示工作表.这显然意味着您无法与工作表交互.它仅用于显示工作表中的数据.

基本设置

创建用户窗体并放置控件,如下所示.我在帖子的末尾添加了一个示例文件.随意修补它并使其更好.您也可以随意调整用户形式以满足您的需求.

    Ret = Application.GetOpenFilename("Excel Files (*.xls*), *.xls*")

    If Ret = False Then Exit Sub Else TextBox1.Text = Ret

    ComboBox1.Clear
