Is it possible for VBA in Excel to assign to a member variable of a
class in a C# COM AddIn? In C# I have:
namespace mySpace
{
[ClassInterface(ClassInterfaceType.AutoDual), ComVisible(true)]
public class myClass : IDTExtensibility
{
public double myDouble;
public myClass(){}
}
}

in VBA I have:
Dim aClass As mySpace.myClass
Sub Testing()
Set aClass = New mySpace.myClass
aClass.myDouble <--------------------This errors 'unkown member'
End Sub

Is there a way to access member variables in my class or must I write
accessor functions?
