东风12型拖拉机:C语言程序设计：设计一个程序来创建一个通讯录

如果你平时有许多同学和朋友的信息，试试在电脑上编写一个我这样的通讯录。很方便的哟。 先新建一个工程，在“工具箱->右键->部件”添加“Microsoft windows common control 6.0”，然后在窗体上添加五个标签，“标题”分别为 “姓名、电话、Oicq、E-Mail、地址”；添加一个文本框（text1）, 然后[复制/粘贴4次]使其成为控件数组；添加一个Listview控件(Listview1),在其属性框中，添加五个“列首”，“文本”值分别为“姓名、电话、Oicq、E-Mail、地址”，“查看属性”为 “3-lvwReport”, 选中“整行选择”，取消“隐藏选择”；添加两个按钮，其标题属性分别为“添加”、“删除”。添加如下代码：
Option Explicit
Dim fileName As String
Private Sub Command1_Click()
'将文本框中的信息添加到列表框中
Dim i As Integer
With ListView1.ListItems.Add()
.Text = Text1(0)
For i = 1 To 4
.SubItems(i) = Text1(i)
Next i
End With
End Sub

Private Sub Command2_Click()
'删除列表框中信息
If ListView1.ListItems.Count > 0 Then
If MsgBox("真的要删除吗？", vbQuestion + vbYesNo + vbDefaultButton2) = vbYes Then
ListView1.ListItems.Remove ListView1.SelectedItem.Index
End If
End If
End Sub

Private Sub Form_Load()
Dim tpStr As String, i As Integer
fileName = App.Path & "\data.txt"
If Dir(fileName) <> "" Then
'加载数据
Open fileName For Input As #1
Do While Not EOF(1)
With ListView1.ListItems.Add()
For i = 0 To 4
Line Input #1, tpStr
If i = 0 Then
.Text = tpStr
Else
.SubItems(i) = tpStr
End If
Next i
End With
Loop
Close #1
End If
End Sub

Private Sub Form_Unload(Cancel As Integer)
Dim i As Integer
Dim tpList As ListItem
'保存数据
Open fileName For Output As #1
For Each tpList In ListView1.ListItems
Print #1, tpList.Text
For i = 1 To 4
Print #1, tpList.SubItems(i)
Next i
Next tpList
Close #1
End Sub

本程序已在windows98+VB6.0环境下调试通过。
