Renumbering PCB pads with a mouse click

Quick way to renumber pads, mostly useful in the pcb library editor.
Click on the pad with the first number and then click on the other pads and they will incremently change numbers.

Sub RenumberPads

Dim Board
Dim Rpad
Dim PadNumber

Set Board = PCBServer.GetCurrentPCBBoard
If Board is Nothing Then Exit Sub
Pcbserver.PreProcess
Set PadObject = Board.GetObjectAtCursor(MkSet(ePadObject),_
AllLayers,"Select Pad To Start With")
PadNumber = PadObject.Name + 1

While Board.ChooseLocation(x,y, "Click Next Pad To Renumber") = True
  Set Rpad = Board.GetObjectAtXYAskUserIfAmbiguous(x,y,MkSet(_
  ePadObject),AllLayers,eEditAction_Change)

  If Not(Rpad is Nothing) Then
     Call PCBServer.SendMessageToRobots(Rpad.I_ObjectAddress,_
     c_Broadcast, PCBM_BeginModify, c_NoEventData)

     Rpad.Name = PadNumber

     Call PCBServer.SendMessageToRobots(Rpad.I_ObjectAddress,_
     c_Broadcast, PCBM_EndModify , c_NoEventData)
  End If

  PadNumber = PadNumber + 1
Wend

Pcbserver.PostProcess
ResetParameters
Call AddStringParameter("Action", "Redraw")
RunProcess("PCB:Zoom")

End Sub

PCB rules and how to access them.

Get access to the PCB rules. Get the width rules and list the details.

Sub GetWidthRule

Dim Board
Dim tmpStr

Set Board = PCBServer.GetCurrentPCBBoard
If Board is Nothing Then Exit Sub

Iterator = Board.BoardIterator_Create
Iterator.AddFilter_ObjectSet(MkSet(eRuleObject))
Iterator.AddFilter_LayerSet(AllLayers)
Iterator.AddFilter_Method(eProcessAll)
Set Rule = Iterator.FirstPCBObject

While Not (Rule Is Nothing)
 If  Rule.Rulekind =  eRule_MaxMinWidth Then
  tmpStr = "Name: " & Rule.Name & vbcrlf
  tmpStr = tmpStr & "Preferred: " & CoordtoMils(Rule.FavoredWidth(eTopLayer))
  tmpStr = tmpStr & "mils" & vbcrlf
  tmpStr = tmpStr & "Minimum: " & CoordtoMils(Rule.MinWidth(eTopLayer))
  tmpStr = tmpStr & "mils" & vbcrlf
  tmpStr = tmpStr & "Maximum: " & CoordtoMils(Rule.MaxWidth(eTopLayer))
  tmpStr = tmpStr & "mils" & vbcrlf
  tmpStr = tmpStr & "Scope1: " & Rule.Scope1Expression & vbcrlf
  tmpStr = tmpStr & "Scope2: " & Rule.Scope2Expression
  ShowMessage( tmpStr )
 End If
 Set Rule = Iterator.NextPCBObject
Wend

Board.BoardIterator_Destroy(Iterator)

End Sub
