在VB中模擬超連結，以瀏覽器開啟網頁

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

Private Sub LblLink_Click()
ShellExecute hWnd, "open", "http://bbs-mychat.com/index.php", vbNullString, vbNullString, conSwNormal
End Sub

Private Sub LblLink_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
LblLink.FontBold = True
LblLink.FontUnderline = True
LblLink.ForeColor = vbBlue
Me.MousePointer = 99
End Sub

Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
LblLink.FontBold = False
LblLink.FontUnderline = False
LblLink.ForeColor = vbBlack
Me.MousePointer = 0
End Sub

應用WINDOWS API時，要如何得知相關常數的定義？

請使用VB工具, API檢視員
