[Closed] Saving rollout definition with file

What’s the best way to save a rollout defintion with a file: I have a complex dotnet rollout that is run when a button is pressed which works fine as a mxs but obviously is’nt saved with the max file.
Here is the simplfied version of the rollout and associated button:

 
fn someFunction param =
(
try(form.close())catch()
maxHandlePointer=(Windows.GetMAXHWND())

sysPointer = DotNetObject "System.IntPtr" maxHandlePointer

maxHwnd = DotNetObject "MaxCustomControls.Win32HandleWrapper" sysPointer
 
form=dotNetObject "form"
 form.Show (maxHwnd)
   
 theImage = dotNetClass "System.Drawing.Image"
  
graph=dotNetObject "label"
 
 showproperties graph
graph.bounds=dotNetObject "system.drawing.rectangle" 40 40 400 400

form.controls.add graph
form.show()
form.size=dotNetObject "system.drawing.size" 500 500
form.backColor=(dotNetClass "system.drawing.color").fromArgb 100 100 100
form.text="Non Linear Morph Control"

)

rollout dummyRollout ""
(
 local param
 
 timer tim interval:5 active:on
 
 on tim tick do if param != undefined do 
 (  someFunction param
  destroyDialog dummyRollout
  
 )
)

att = attributes "testAtt"
(
 rollout attRol ""
 (
  button runFn "runFn"
  
  on runFn pressed do
  (   
   createDialog dummyRollout pos:[-2000,-2000]
   dummyRollout.param = 800
  )
 )
)
myBox = box isSelected:on
custAttributes.add myBox att 

I don’t want to place defintion of rollout after the “do” clause as it is lengthy and also its going to be an executed string anyway, which creates more problems.
Thanks in advance.
