vba Excel Useform：如何隐藏应用程序但在任务栏中有图标

Excel Useform: How to hide application but have icon in the taskbar

提问by Ali Lumsden

What I want to have is Application.Visible = False, so that my users cannot see the excel/worksheets, only the userform.

我想要的是 Application.Visible = False，这样我的用户就看不到 excel/工作表，只能看到用户表单。

I have got this to work by using this code:

我通过使用此代码使其工作：

Private Sub Workbook_Open()
Application.Visible = False
UserForm2.Show
End Sub

However, this only has the userform floating around in the background. My users will have other applications open, and I want them to easily change to the userform by having an icon visible on the taskbar.

但是，这只会使用户表单在后台浮动。我的用户将打开其他应用程序，我希望他们通过在任务栏上显示一个图标来轻松更改为用户表单。

I have found the following example online, but I cannot seem to find where to place this code. Still very new to this, so hopefully I have the right code for the job. If I do, can someone talk me through where to place it, as it is not working when I paste it into my code?

我在网上找到了以下示例，但似乎找不到放置此代码的位置。对此仍然很陌生，所以希望我有适合这项工作的代码。如果我这样做了，有人可以告诉我把它放在哪里，因为当我将它粘贴到我的代码中时它不起作用？

(i.e. should it go under 'userform' or 'this workbook: declarations' etc. )

（即它应该在“用户表单”或“此工作簿：声明”等下）

Thank you,

谢谢，

Try placing this code in the userforms code module:

尝试将此代码放在用户表单代码模块中：

So, as you may noticed this won't work on the 64 bit version of excel.

因此，正如您可能注意到的，这不适用于 64 位版本的 excel。

I made it compatible by adding conditionals to the code i took from here.

我通过向我从这里获取的代码添加条件来使其兼容。

In case you're wondering how you can make API functions compatible with 64 bits versions of Excel hereit's an excellent article that will get you through.

I haven't tested this yet on 32 bits versions of excel but it should work without problems.

我还没有在 32 位版本的 excel 上测试过这个，但它应该可以正常工作。
