cbSize As Long
dwMajorVersion As Long
dwMinorVersion As Long
dwBuildNumber As Long
dwPlatformID As Long
End Type
Private Declare Function DllGetVersion _
Lib "Shlwapi.dll" _
(dwVersion As DllVersionInfo) As Long
Private Function GetIEVersionString() As String
Dim DVI As DllVersionInfo
DVI.cbSize = Len(DVI)
Call DllGetVersion(DVI)
GetIEVersionString = "Internet Explorer " & _
DVI.dwMajorVersion & "." & _
DVI.dwMinorVersion & "." & _
DVI.dwBuildNumber
End Function
