"I see. Are you also absolutely certain that inputs only ever contain a single value and that value is not null? IGH_Structure is a pretty minimal interface but GH_Structure(Of T) has some useful features for this sort of thing. Since you know the…"

"Input parameter <nickname> failed to collect data see attached file RegisterInputParmas code is: Protected Overrides Sub RegisterInputParams(pManager As Grasshopper.Kernel.GH_Component.GH_InputParamManager)…"

""name of the user" because we are developing a collaborative design tool. "team member" would be a better description. I am making a prototype in vb.net with a listview that shows the shared parameters between different…"

""name of the user"? sorry, I must be confused today. You're looking to populate a windows.forms.listview with input parameter names? -- David Rutten david@mcneel.com Poprad, Slovakia"

"I want to use a panel with the name of the user as input parameter for a custom GH_Component to be listed in a cell of a Listview on a Windows.Form when the user hits a check button."

"Nicknames and even Names can change. It's always dangerous to rely on them. Accessing parameter through their index is the recommended way. Also note that the volatile data may not have any branches. In that case Branch(0) will throw an…"

"Yes"

"What I found that worked is: Dim myInputParameter as String = Me.Params(x).VolatileData.Branch(0).Item(0).ToString x being the number given when registering the parameter input But I guess that it would be better to find the nickname of the…"

"RegisterInputParams and RegisterOutputParams are called from within the constructor of GH_Component. It is possible to remove and add parameters later as well (though never during a solution) by using the Params objects. So if you're inside a…"

"Tried it, but if that input parameter is not connected, I still get the error "failed to collect data"..."

"Probably changed in new version? Now pManager doesn't have a Register_StringParam method... I use pManager.AddTextParameter("String", "I", "Input file path", GH_ParamAccess.item) How can we make an input parameter…"

"Can you tell me the setting in vb.net to start a GH file? Spares me three clicks and typing Gras :)"

"hmm, I am using Visual Studio 2012, not the express edition and VB not C#. Any idea how I could debug a GH component here? Now I have to close GH and Rhino every time and replace the *.gha file."

"Hi David, Do you already have an answer to the debugging question? What is the best way to debug a vb.net script that makes a new GH_component in VS2012? E.g. I added a second windows form project (VS needs an executable project for…"

"What should one do, when Rhino gets slow? I noticed that even if you disconnect a Grasshopper component that caused the problem, the machine stays slow. Only a restart helps. Is there a command that frees unused memory?"
