Putting Enable Macros Button Into Userform Type Display

In reference to my other topci here: Userform Error

In this workbook I have successfully made it act like a userform calculator, the user does not ever see the actual sheets in the workbook, their only interface is the Userform calculator I created.

This is exactly how I want it, they do not need to see the sheets, nor do I want them to.

This leads me only to my next problem... Some of the users obviously wont have Macros automatically enabled, what I am wondering is, is there a way to put the normal "Enable Macros" button which appears along the top of a macro containing workbook when opened, I want to put this button into a userform like display without showing the workbook at all.

So here the process I envision:

1. User double clicks the file
2. It opens and automatically goes invisable (like it does already)
3. If the user does not have macro enabled, a userform like box appears and says "Please enable Marcros to user" with a button below for "Enable" and "Exit"
4. If exit is pressed excel closes
5. If enabled is pressed Macros are enabled and then they will automatically see my calculator userform like normal.

As you see, at no point do I want them to see excel or a workbook, just userforms so its not like they are using excel at all.

I have searched around the net and found a few ideas to tackle this, mainly one that has a "Prompt" workbook that shows when macros are disabled, but that is not ideal for me. However perhaps I could just edit this "prompt" code thing for my situation?

Here is the prompt sheet code I talked about:

Code:
Option Explicit
Private Sub Workbook_Open()
With Application

[Code]....

How to use:

Open an Excel workbook Select Tools/Macro/Visual Basic Editor in the VBE window, select View/Project ExplorerSelect the This Workbook module Copy and paste the code above into this ModuleNow select File/Close and Return To Microsoft Excel Don't forget to save your changes...

8. Name one of your sheets "Prompt"
