VB读写TXT文件

Private Sub Command1_Click() '读文件
Open "d:a.txt" For Input As #1
Dim Lines As String
Dim NextLine As String
Dim i As Integer

Do While Not EOF(1)
On Error Resume Next
Line Input #1, NextLine
Lines = Lines & NextLine & Chr(13) & Chr(10)
Loop

Close #1
Text1.Text = Lines
End Sub

Private Sub Command2_Click() '写文件
Open "d:a.txt" For Output As #1
Print #1, Text1.Text
Close #1
End Sub

'如果要处理的是程序目录所在的a.txt那么应该是这样写：
'Open app.path+"/a.txt" For Input As #1
