patch through points

hello
i need a very simple thing - a "live" patch surface through some points (not edge curves) in grasshopper.
i've been struggling with it for a while now. i need to use VB script, but i'm only familiar with rhinoscript and VB in GH seems to have different syntax and semantics.
could you please help me out?

thanks!

Hi Jan,

Patch is not exposed, nor in Grasshopper, nor in RhinoScript, nor in the SDK. So you're going to have to make it all from scratch. Are you sure you want this?

actually, i'm not sure.
i've been thinking of something like this
app.RunScript("_-patch uSpans=" & uSpans & " vSpans=" & vSpans & " _Enter")
but it doesn't work for me. maybe the source has to baked or i don't know.
what i actually need is a surface through points. i don't know the number nor positions of the points in advance. it doesn't have to be a patch but i want it to be live.
so you think it's not going to be easy?

I thought someone had already done some work for this:

Yes, bake the points, patch, delete the points...

yes, i've seen the example. don't know why, but it doesn't work for me.
i've been thinking of creating a set of control curves out of the points and then creating a loft using the curves... maybe?

yes, not working cause it is set up for curves. I have not looked at it in a while though...your suggestion might work given your curves make good patch geometry.
