Solved!Keeping this topic unlocked so others can use it for reference.Will this line of code work? It's part of a keybind generator script.
function Jeepserver_OpenGui(%guiname)
{
canvas.pushDialog(%guiname);
}

Visual Studio (C# 2010) seems to show a problem.
It basically is supposed to set a newly generated .cs file for a new generated keybind to open a GUI when you press the key.
%FO is a FileObject.
%funcname is the GuiControl's name that a user picked from a PopupMenu List.
