File Version Information

Does any one know how to get a files version information using the Windows API. I already know how to use the GetFileVersionInfo to get a files version number. But what I'm really interested in is getting a files advanced version information such as 'Product Name', 'Internal Name' and 'Company Name'. Any examples would be helpful.

Here, try this, it extracts all the File Information, (Works only on 32-bit Files):

Add a Textbox, CommandButton and CommonDialogbox to a Form..

Code:

---

private 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
private Declare Function GetFileVersionInfoSize Lib "Version.dll" Alias "GetFileVersionInfoSizeA" (byval lptstrFilename as string, lpdwHandle as Long) as Long
private Declare Function VerQueryValue Lib "Version.dll" Alias "VerQueryValueA" (pBlock as Any, byval lpSubBlock as string, lplpBuffer as Any, puLen as Long) as Long
private Declare Function lstrcpy Lib "kernel32" Alias "lstrcpyA" (lpString1 as Any, lpString2 as Any) as Long

private Sub Command1_Click()
    Dim sVerInfo(7) as string
    Dim sInfo as string
    Dim sValue as string
    Dim sFile as string
    Dim sData() as Byte
    Dim lSize as Long
    Dim lPointer as Long
    Dim iIndex as Integer
   
    on error GoTo OpenError
    With CommonDialog1
        .CancelError = true
        .ShowOpen
        sFile = .FileName
    End With
    Text1 = ""
    'get the Length of the FileVersion Information
    lSize = GetFileVersionInfoSize(sFile, byval 0&)
    'Create a Buffer to hold the Version Info
    ReDim sData(lSize)
    'get the Version Info
    If GetFileVersionInfo(sFile, 0&, lSize, sData(0)) then
        'Extract the Details of the Version Info
        sVerInfo(0) = "CompanyName"
        sVerInfo(1) = "FileDescription"
        sVerInfo(2) = "FileVersion"
        sVerInfo(3) = "InternalName"
        sVerInfo(4) = "LegalCopyright"
        sVerInfo(5) = "OriginalFileName"
        sVerInfo(6) = "ProductName"
        sVerInfo(7) = "ProductVersion"
        for iIndex = 0 to 7
            sInfo = "\StringFileInfo\040904E4\" & sVerInfo(iIndex)
            If VerQueryValue(sData(0), sInfo, lPointer, lSize) then
                sValue = Space(lSize)
                lstrcpy byval sValue, byval lPointer
                Text1.SelText = sVerInfo(iIndex) & ": " & sValue
                Text1.SelText = vbCrLf
            End If
        next
    End If
OpenError:
End Sub
