Searching for "un"-connected components on the canvas

Hey to all.

I'm fairly new into programming with the VB-Component in Grasshopper and I'm limited with my (poor) programming know-how. But I hope you can feel a little sympathy for me ;-).

Is it possible to search for components, which have no source connected on their inputs ?

Any Help would be greatl appreciated

Thx alex

Not directly, but it's certainly possible to iterate over all objects in a document and figure out which objects don't have inputs.

Thx David for the fast reply.

I understand the things you did. So all I have to do is to search for the objects which have a param.SourceCount > param.Sourcecount -1 for finding objects which have at least one "open" input ?

If you're specifically searching for components then the code becomes a bit easier. If you want to include in your search other types of objects as well (as I did in my example code) then you need to use the AppendToAttributeTree trick.

Searching for components with specific input topology might look like the attached.
