Alias "MessageBox" (ByVal hWnd As Integer, _
ByVal txt As String, ByVal caption As String, _
ByVal Typ As Integer) As Integer
'定义一些要调用参数
Const MB_ICONQUESTION = &H20L
Const MB_YESNO = &H4
Const IDYES = 6
Const IDNO = 7
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim RetVal As Integer ' 存储返回的值.
RetVal = MBox(0, "调用WinApi成功否？", "Windows API 信息框", _
MB_ICONQUESTION Or MB_YESNO)
' Check the return value.
If RetVal = IDYES Then
MsgBox("您选择了是")
