To identify a process later in Windows you start them with the WIN32-function CreateProcess. That function returns a structure of type PROCESS_INFORMATION where you can find both the process ID and a handle to the process. Later you can use these to both identify and control the process. Assigning a predetermined process ID, as far as I know, is not possible.

That was all for low level C/C++ programming and as the zone-selection of this question indicates you want something for VB. I'm not too familiar with VB but I undestand it includes some wrapper functionality that allows you to call those WIN32-functions, so that's a starting point for you.

You can't *assign* a PID to a process, but you can *identify* it.

Regards,

Rob.
Set objShell = CreateObject("WScript.Shell")
Set objExec = objShell.Exec("c:\Program Files\Microsoft Office 2007\Office12\EXCEL.EXE")
strPID = objExec.ProcessID
MsgBox strPID

OK, sure.  This code will show you the process ID for the latest instance of a process that has a name as defined by strProcessName

Regards,

Rob.
Const wbemFlagReturnImmediately = &h10
Const wbemFlagForwardOnly = &h20

strComputer = "."
strProcessName = "iexplore.exe"

Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2")
Set colItems = objWMIService.ExecQuery("SELECT CreationDate,ProcessID FROM Win32_Process WHERE Name='" & strProcessName & "'", "WQL", wbemFlagReturnImmediately + wbemFlagForwardOnly)

intProcID = 0
dteStarted = CDate("01-01-1601")

For Each objItem In colItems
	If CDate(WMIDateStringToDate(objItem.CreationDate)) > dteStarted Then
		dteStarted = CDate(WMIDateStringToDate(objItem.CreationDate))
		intProcID = objItem.ProcessId
	End If
Next

If intProcID > 0 Then WScript.Echo "Process ID " & intProcID & " was started at " & dteStarted

Function WMIDateStringToDate(dtmDate)
	WMIDateStringToDate = CDate(Mid(dtmDate, 5, 2) & "/" & _
	Mid(dtmDate, 7, 2) & "/" & Left(dtmDate, 4) _
	& " " & Mid (dtmDate, 9, 2) & ":" & Mid(dtmDate, 11, 2) & ":" & Mid(dtmDate,13, 2))
End Function
