You can use ShellExecute:

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

Dim Retval

    Retval = ShellExecute(Me.hwnd, "Open", "YOUR_URL_GOES_HERE", "", App.Path, 1)

>Suppose I have a picture box with the onclick event code so that it open a browser and go to a specific URL... how can we do that?
