Ret& = ShellExecute(0, "open", "c:\help.htm", "", vbNull, SW_SHOWNORMAL)
Ret& = ShellExecute(0, "open", "", "", vbNull, SW_SHOWNORMAL)
Private Sub Help_btn_Click()
Ret& = ShellExecute(0, "open", "", "", vbNull, SW_SHOWNORMAL)
End Sub

Private 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 Long) As Long

Hi Rajesh,

It works fine when I use the line :
Ret& = ShellExecute(0, "open", "", "", vbNull, SW_SHOWNORMAL)

However when I want to open a offline html page with:
Ret& = ShellExecute(0, "open", "help.html", "", vbNull, SW_SHOWNORMAL)
it doesn't work..

Can you help me out ?

give the full path:

Ret& = ShellExecute(0, "open", "c:\html\help.html", "", vbNull, SW_SHOWNORMAL)

Maybe you have to use the file protocol , like this
Ret& = ShellExecute(0, "open", "file://c:\html\help.html", "", vbNull, SW_SHOWNORMAL)

If you prefer to have programmatic control over the process rather than just shelling out (so that you can get better error information, for example), you could do this instead:

    Dim oIE As Object
    Set oIE = CreateObject("SHDocVw.InternetExplorer")
    oIE.Visible = True
    oIE.Navigate ""
    Set oIE = Nothing

If you prefer to use early binding, the TypeLib to Reference in VB is called "Microsoft Internet Controls".
