在VB中如何用textbox接收结果
代码如下：
Private Sub Command1_Click()
Dim IPC As String
Dim i As Integer
For i = 1 To 254
IPC = "192.168.1." & i
If ping(IPC) Then
Print IPC & "--PING成功"
Else
Print IPC & "--PING失败"
End If
Next
End Sub
我想用textbox去接收结果，但不知道如何设置，请高手解答。谢谢，本人菜鸟！
[解决办法]
看着楼主头像上那妞的表情我就一身发冷.....
Print换成Text1.Text=text1.text &
然后在Next前加一句Text1.text=text1.text & vbcrf
