OCX control: Sub New() is not accessible in this context because it is 'Private'

Question

Recently I've been trying to create an activeX control and use it in some vb.net code. After much struggle i created my control in vb6 and generated the ocx file. I've been trying to use it as shown in microsoft docs here but to no avail. On :

myActiveX = New MyActiveXComponent.MyClass()

i keep getting

MyActiveXComponent.MyClass.Private Sub New() is not accessible in this context because it is 'Private'

I can import it to toolbox and use that way but i would prefer not to, im using visual studio 2005. Also i have an ocx which to my supprise i can use both ways(not mine) so i suspect there's something wrong with mine, but i can't figure out what.

It looks like you are creating an instance if class called MyClass. Is this a class you have defined in your ocx? — tcarvin
@tcarvin Yes trying to instance an user control in this case MyClass which is contained in the ocx, you can find the source code here support.microsoft.com/en-us/help/315847/…. — chomsk
@ChrisDunaway I can't write sub new in vb6 at all, as far as i know New should be inside wrapper generated by interop, and it is looking at object browser, but its inhered from System.Object, where in the other working ocx it's a member of the class, almost as it was a class module. — chomsk

You are mixing Classes and Controls up a bit. But in any case, if you want your class to be publicly creatable you need to set the Instancing, and I suggest using MultiUse.
