嗯,使用shell
比如 shell("cmd /c del /f /s /q ""%userprofile%\local settings\temporary internet files\*.*""")
注意 字符串里面""代表一个"

/c 改为 /k 调用完命令以后不关闭CMD窗口。
CMD 后面的选项很多,在CMD窗口输入 cmd /? 按回车可以查看。

我测试可以用, 你试下,以下代码要隐藏的控件是button1,从button1上第一次移到窗体上会无效,鼠标停留在button1上无效
Private xy As Point
Private data As Integer
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Timer1.Enabled = False
Timer1.Interval = 1000
End Sub
Private Sub Form1_MouseMove(sender As Object, e As MouseEventArgs) Handles Mwhatsapp网页版电脑版白屏e.MouseMove
Dim back As Point = Me.PointToClient(Control.MousePosition)
If xy = back Then Timer1.Enabled = True : Exit Sub
Button1.Visible = True
xy = back
End Sub
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
data = data + 1
If data = 3 Then Button1.Visible = False : Timer1.Enabled = False : data = 0
End Sub
