vb 在字符串中插入字符

我想在字符串111111111111第三位,第六位,第九位,第十二插入字符2,成为1112111211121112.我用print语句输出结果成了111 2 111 2 111 2 111 2 ,2和1之间有空格,怎么样写才能把空格去掉哩?谢谢各位达人啰~请写清楚点~我是菜鸟~

Answer 1

'我插入的没有空格啊,你是怎么插入的? 要不你把你插入"2"的地方换成Trim("2")试试看

Private Sub Form_Click()
Dim a As String, b As String
a = "111111111111"
For i = 1 To Len(a) Step 3
b = b & Mid(a, i, 3) & "2"
Next
Print b
End Sub

Answer 2

Private Sub Command1_Click()
Dim a As String
Dim c As String
Dim b(4) As String
Dim i As Integer
a = "111111111111"
Text1 = a
For i = 1 To Len(a) Step 3
b(i / 3) = Mid(a, i, 3) & "2"
Print b(i / 3);
Next
For i = 0 To 4 'Len(a) / 3
c = c & b(i)
Next
Text2 = c
End Sub

Answer 3

Replace("111 2 111 2 111 2 111 2","1 2","12")
