Executing Files

How do I set the working directory of a program I want to execute from VBA? by dds82
Posted: 7 Aug 02 (Edited 7 Aug 02)

You use Windows' built-in ShellExecute() API function.  Just copy and paste this declaration into a module:

Public Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _
    (ByVal hwnd As Long, _
     ByVal lpOperation As String, _
     ByVal lpFile As String, _
     ByVal lpParameters As String, _
     ByVal lpDirectory As String, _
     ByVal nShowCmd As Integer) As Long

To execute c:\foo\foo.exe, you would say:

'5 is SW_SHOW, to show the window

If the program takes command-line arguments, you can pass them in using the fourth parameter (instead of vbNullString).
