Question: I am trying to make a webpage which scrolls content, and when it reaches the bottom of the content continue to scroll the bottom off the page, while scrolling the top back on - so the bottom and the top will be on screen at the same time. Like the `<marquee>` tag, but vertically.

Only stuff I've managed to think up so far is (on load I use `setInterval()` to run this every 75ms)

```
function doScroll() {

window.scrollBy(0,1);

if($(window).scrollTop() + $(window).height() == $(document).height()) {
    window.scrollTo(0,0);   
}

}

```

You should be able to debug the C#.NET dll by setting the start action under Debug to

and specify the VB6 executable as the program.

I know this works as I use this to debug a .NET/C# plugin for an old VB6 application.

It shouldn't matter how many other dlls (.NET or otherwise) you have to go through to get to the code you are trying to debug.
This might not be correct, but I believe VB 2010 uses what? .NET 4.0, right? VB6 was created in like...1994 I believe, so it would be <= .NET 1.0. The binaries would more than likely be incompatible.
