API Enable

anyone know witch API to use when I want to enable/disable a command-button just with API. SetWindowLong, SendMessage or some other API?

The EnableWindow API should do it.

Code:

---

Private Declare Function EnableWindow Lib "user32" (ByVal hwnd As Long, ByVal fEnable As Long) As Long

Private Sub Command1_Click()

    'Disable Command1. Pass True instead of False to enable it
    EnableWindow Command1.hwnd, False

End Sub
