Try api to load Library in runtime to use it - - -
option explicit
Private Declare Function LoadLibrary Lib "kernel32" Alias "LoadLibraryA" (ByVal lpLibFileName As String) As Long
Private Sub Form_Load()
Loadlibrary( app.path & "\msconf.dll")
End Sub
Now you can use it in run time. Here msconf.dll is an example. You can use any dll file in the place of msconf.dll.
Enjoy...
