推荐答案

在这里，您可能会不得不更改一些代码，尽管操作不便. :P

Here you go you might have to change some of the code though ill walk you through it :P

Dim db_con As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & "DATABASE LOCATION GOES HERE)

        db_con.Open()

        Dim ds As New DataSet

        Dim query1 As String
        query1 = " SELECT * FROM TABLEGOESHERE"
        Dim da As OleDbDataAdapter
        da = New OleDbDataAdapter(query1, db_con)
        da.Fill(ds, "VirusMD5")
        Dim tblstr As String = Nothing
        Dim cmd As OleDbCommand
        Dim dr As OleDbDataReader
        Dim _Ecount As Integer
        _Ecount = ds.Tables("THE TABLE YOU NEED TO READ FROM").Rows.Count
        signatures = _Ecount
        cmd = New OleDbCommand("SELECT * FROM VirusMD5", db_con)
        dr = cmd.ExecuteReader
        While dr.Read
             'You need to figure out how many items their are and what you are reading. See link below
             Combobox1.Items.Add(dr(0))
'0 Stands for the first items rows are handled automatically.

        End While


        GoTo ende



        End If

我不对列表视图执行任何操作，因为我不熟悉它，但是从数据库获取数据是相同的.
要使其执行您想要的操作，请编辑代码的这一部分.

I do not do anything we listviews because I am not familiar with it but getting the data from the database is the same.
To make it do what you want to do edit this part of the code.

Combobox1.Items.Add(dr(0))

将该行替换为向您的listveiw添加数据.希望对您有帮助

Replace that line with adding data to your listveiw. Hope this helps
