D:\aa.txt有一些字符
如
345345364u
23657567rtre
34535327r
43564hfhfh
....
....
等等
点击Command1,读取aa.txt,重第一行开始,每次一行循环显示在text1里,该怎么写
如第一个显示345345364u,然后清空text1再显示23657567rtre,然后再清空显示34535327r,以此类推

while not eof(1)
line input #1,istr
text1=istr
wend
这需要设置一个public变量或static变量i
用来记录本次点击时第i次点击 需要读第i行。
Dim istr As String
If Not EOF(1) Then
Line Input #1, istr
Text1 = istr
Else
Close #1
MsgBox "文件已经读完"
End IfEnd SubPrivate Sub Form_Load()
Open "c:\a.txt" For Input As #1End Sub
Text1 = sData(num)
num=num+1
else
