Salut,
Utilise plutot Shellexecute qui utilise le navigateur par défaut sans avoir à spécifier son emplacement.
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 url as string
url = "
[ Lien ]" & Text1.text
ShellExecute(0, "open", url , vbNullString, vbNullString, vbNormalFocus)
