Is there a way to compile VB6 in 2018?

Question

The reason I need this is I'm porting a VB6 app and I'm getting a very small difference in the arithmetic between VB6 and C#. I just need to test a couple calculations. The one I'm most interested in is how this comes out:

Round(2.24984, 1)

If that comes out to 2.3 in VB6 I'm done, it's figured out. But if not there are a couple steps leading up to that which could also be the problem.

An online VB6 fiddle would be ideal but I can install a virtual machine if I have to.

Answer 1

No, you cannot compile a VB6 project directly in Visual Studio 2017.

What you can do is open the project in Visual Studio 2008 and migrate it to VB.Net using the Visual Basic Update Wizard. (The migrated code will likely have errors you will have to fix yourself.) Once this is done, you can open the migrated project in Visual Studio 2017 (the current production release of Visual Studio).
