有这样一段代码,因为本人刚学VB不久,所以不明白它是什么意思.有哪位高手帮忙解释一下啊,谢谢!
Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
If Shift = 6 Then
If Not txtCode.Visible Then
frmMain.Height = 7260
txtCode.Visible = True
Else
frmMain.Height = 3300
txtCode.Visible = False
End If
End If
End Sub
尽量详细一些,谢谢!!

Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
If Shift = 6 Then 'SHIFT ,CTRL 和 ALT 键这些位分别对应于值 1、2 和 4,shift=6就是在窗口上同时按下Ctrl+Alt键
If Not txtCode.Visible Then '如果TXTCODE控件(应该是个文本框)Visible 属性不为真.即不可见
frmMain.Height = 7260 '改变frmmain窗口高度
txtCode.Visible = True '设置Txtcode控件为可视
Else
frmMain.Height = 3300 改变frmmain窗口高度
txtCode.Visible = False '设置Txtcode控件为不可见 End If
End If
End Sub
