Form1.Designer.Vb or Form1.Vb??

Dear folks,

I’ve got a group of VB projects in my Solution Explorer. One is a Windows Service project, other a Application Console and the last one is a Windows Applicaton. Fine.

When I take Windows Application project and add a new Windows Form I see Form2.Vb and nothing else. As usual. But I’ve added MSDVideo project sample and I see now how the ones VB forms own when you expand a “xxxxxdesigner.VB“

I mean, for example if add in that project a new form named Form4 I’ll obtain a couple of references: Form4.Vb-> Form4.Designer.Vb

I don’t get the point at all how do the same in the other projects. I don’t mind in the slightest but I feel curiosity for this behaviour. Why, I wonder, at the end of the day is the same or not

Thanks for any input or comment,
