Macro For Stepping Into #import Wrapped COM Methods

When using #import to create wrapper classes for your own C++ COM objects, debugging and stepping into the COM methods can be tedious because you have to first step into the wrapper class and then COM object wrappers for many of the method's paramenters (e.g. _bstr_t and _variant_t), before you finally get to the raw method. To solve this I have written the macro StepInComFunc to do all the stepping in and out automatically for you, effectively stepping you directly into the source code for the method being called. Obviously the COM object will have to have been built with debug information. I find it useful to map this macro to the shortcut key ALT+F11.
Sub StepInComFunc()

 Application.Debugger.StepInto

 Dim nMaxParams, nCount
 nCount = 0
 nMaxParams = 20

 Do While ((ActiveDocument.Name = "COMUTIL.H" 
 Or ActiveDocument.Name = "ATLBASE.H") 
 And nCount < nMaxParams)

  Application.Debugger.StepOut
  Application.Debugger.StepInto
  nCount = nCount + 1
 Loop

 if (ActiveDocument.Name = "COMIP.H") then
  Application.Debugger.StepOut
  Application.Debugger.StepInto
 End If

 if (ActiveDocument.Name = "COMIP.H") then
  Application.Debugger.StepOut
  Application.Debugger.StepInto
 End If

 if (InStr(ActiveDocument.Name, ".tli") > 0) then
  Application.Debugger.StepOver
  Application.Debugger.StepInto
 End If

 nCount = 0
 Do While ((ActiveDocument.Name = "COMUTIL.H" 
 Or ActiveDocument.Name = "ATLBASE.H") 
 And nCount < nMaxParams)
  Application.Debugger.StepOut
  Application.Debugger.StepInto
  nCount = nCount + 1
 Loop

End Sub
