How to get the process ID of the current Excel instance, through VBA, without using the caption?

Question

How can I get the process ID of the current Excel instance that my VBA code is running in? I don\'t want to asking for it by the name in the caption, which causes problems when

Answer 1

As a vba n00b, some other things I did not know

1. The Declare statement goes at the top. VBA will complain if the declare statement is inserted after a sub declaration

   For example, this will work

   Declare Function GetCurrentProcessId Lib "kernel32" () As Long
   
   Sub Update
     ...
     ...
   End Sub
   

   But this will not work

   Sub Update
     ...
     ...
   End Sub
   
   Declare Function GetCurrentProcessId Lib "kernel32" () As Long
   

2. Here is how we display the PID in a messagebox in vbscript

   Set app = CreateObject("Excel.Application")
   MsgBox("Excel PID is " + CStr(app.Run("GetCurrentProcessId")))
   

Hope this helps someone
