[ACCEPTED]-VBA Shell and Wait with Exit Code-shell
Accepted answer
Have a look at WaitForSingleObject and GetExitCodeProcess functions.
Example Usage:
Private Declare Function GetExitCodeProcess Lib "kernel32" (ByVal hProcess As Long, lpExitCode As Long) As Long
Private Declare Function WaitForSingleObject Lib "kernel32" (ByVal hHandle As Long, ByVal dwMilliseconds As Long) As Long
Private Declare Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Long, ByVal bInheritHandle As Long, ByVal dwProcessId As Long) As Long
Private Declare Function CloseHandle Lib "kernel32" (ByVal hObject As Long) As Long
Private Declare Function FormatMessage Lib "kernel32" Alias "FormatMessageA" (ByVal dwFlags As Long, lpSource As Any, ByVal dwMessageId As Long, ByVal dwLanguageId As Long, ByVal lpBuffer As String, ByVal nSize As Long, Arguments As Long) As Long
Public Const INFINITE = &HFFFF
Public Const PROCESS_ALL_ACCESS = &H1F0FFF
Sub RunApplication(ByVal Cmd as String)
lTaskID = Shell(Cmd, vbNormalFocus)
' Get process handle
lPID = OpenProcess(PROCESS_ALL_ACCESS, True, lTaskID)
If lPID Then
' Wait for process to finish
Call WaitForSingleObject(lPID, INFINITE)
' Get Exit Process
If GetExitCodeProcess(lPID, lExitCode) Then
' Received value
MsgBox "Successfully returned " & lExitCode, vbInformation
Else
MsgBox "Failed: " & DLLErrorText(Err.LastDllError), vbCritical
End If
Else
MsgBox "Failed: " & DLLErrorText(Err.LastDllError), vbCritical
End If
lTaskID = CloseHandle(lPID)
End Sub
Public Function DLLErrorText(ByVal lLastDLLError As Long) As String
Dim sBuff As String * 256
Dim lCount As Long
Const FORMAT_MESSAGE_ALLOCATE_BUFFER = &H100, FORMAT_MESSAGE_ARGUMENT_ARRAY = &H2000
Const FORMAT_MESSAGE_FROM_HMODULE = &H800, FORMAT_MESSAGE_FROM_STRING = &H400
Const FORMAT_MESSAGE_FROM_SYSTEM = &H1000, FORMAT_MESSAGE_IGNORE_INSERTS = &H200
Const FORMAT_MESSAGE_MAX_WIDTH_MASK = &HFF
lCount = FormatMessage(FORMAT_MESSAGE_FROM_SYSTEM Or FORMAT_MESSAGE_IGNORE_INSERTS, 0, lLastDLLError, 0&, sBuff, Len(sBuff), ByVal 0)
If lCount Then
DLLErrorText = Left$(sBuff, lCount - 2) ' Remove line feeds
End If
End Function

This functionality has been wrapped up in 1 the ShellAndWait function.
Excellent write up on it here.
