I would like to retrieve the version number of a program without running it, so I can compare it to a newer version number and update as needed.
Any ideas...?

Easier to watch the date/time stamp. Different time/date = different version. Later = newer.

Otherwise you'ld have to diddle with an API call to look at properties (assuming that they used the App.Major/.Minor properties).

I couldn't get it to work because it was taking too much time for too few points, but here is where i left off.  i am pretty sure 95% of it is correct, just i think i need a type declaration for the data i am passing called pBlock.


Public Declare Function GetFileVersionInfo Lib "version.dll" Alias "GetFileVersionInfoA" (ByVal lptstrFilename As String, ByVal dwHandle As Long, ByVal dwLen As Long, lpData As Any) As Long
Public Declare Function GetFileVersionInfoSize Lib "version.dll" Alias "GetFileVersionInfoSizeA" (ByVal lptstrFilename As String, lpdwHandle As Long) As Long
Public Declare Function VerQueryValue Lib "version.dll" (pBlock As Any, ByVal lpSubBlock As String, ByVal lplpBuffer As Long, puLen As Long) As Long


Sub GetFileVersion()
Dim fname As String
Dim lenFV As Long
Dim Version As Long
Dim VersionLen As Long
Dim pBlock As String

fname = "C:\Program Files\Microsoft Office\Office\EXCEL.EXE"

lenFV = GetFileVersionInfoSize(fname, 0)

GetFileVersionInfo fname, 0, lenFV, pBlock

VerQueryValue pBlock, "\\StringFileInfo\\040904E4\\FileVersion", _
              Version, _
              VersionLen

MsgBox Version

End Sub
