关于界面
关于界面代码分析:
Private Sub Label6_Click()
Dim Email
Email = ShellExecute(0&, vbNullString, "mailto:zcjvcbe@263.net", vbNullString, vbNullString, vbNormalFocus)
End Sub
Private Sub Label6_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
End Sub
Private Sub OK_Click()
Unload Me
End Sub
资料查询界面:
代码分析:
Private Sub Check1_Click(Index As Integer)
Dim i As Integer
For i = 0 To 10
Text1(i).Enabled = Check1(i).Value
Next i
'判断性别输入是否有效
Option1(0).Enabled = Check1(3).Value
Option1(1).Enabled = Check1(3).Value
'判断年龄输入是否有效
Frame2.Enabled = Check1(4).Value
For i = 0 To 1
Check2(i).Enabled = Frame2.Enabled
Next i
End Sub
Private Sub Command1_Click() '模糊查询
On Error GoTo ErrHandle
'判断昵称查询
If Check1(0).Value = 1 And Not IsNull(Text1(0).Text) Then
SQLadd = SQLadd + " and Love like'*" + Text1(0).Text + "*'"
End If
'判断QQ查询
If Check1(1).Value = 1 And Not IsNull(Text1(1).Text) Then
SQLadd = SQLadd + " and Oicq like'*" + Text1(1).Text + "*'"
End If
