我已经成功地自学了如何从MySQL数据库中提取数据并将其绑定到ListView控件(ListViewCard)。
现在我无法弄清楚如何使用SelectedIndexChanged事件来记录记录并填充表单上的其他一些控件(即7个文本框,2个组合框和2个日期时间戳)。
非常感谢您的帮助。这是我的代码:
Private Sub loadCard()
Try
'FOR MySQL DATABASE USE
'Dim dbQuery As String = ""
'Dim dbCmd As New MySqlCommand
'Dim dbAdapter As New MySqlDataAdapter
Dim dbTable As New DataTable
Dim i As Integer
If dbConn.State = ConnectionState.Closed Then
dbConn.ConnectionString = String.Format("Server={0};Port={1};Uid={2};Password={3};Database=accounting", FormLogin.ComboBoxServerIP.SelectedItem, My.Settings.DB_Port, My.Settings.DB_UserID, My.Settings.DB_Password)
dbConn.Open()
End If
dbQuery = "SELECT *" & _
"FROM cc_master INNER JOIN customer ON customer.accountNumber = cc_master.customer_accountNumber " & _
"WHERE customer.accountNumber = '" & TextBoxAccount.Text & "'"
With dbCmd
.CommandText = dbQuery
.Connection = dbConn
End With
With dbAdapter
.SelectCommand = dbCmd
.Fill(dbTable)
End With
ListViewCard.Items.Clear()
For i = 0 To dbTable.Rows.Count - 1
With ListViewCard
.Items.Add(dbTable.Rows(i)("ccID"))
With .Items(.Items.Count - 1).SubItems
.Add(dbTable.Rows(i)("ccNumber"))
.Add(dbTable.Rows(i)("ccExpireMonth"))
.Add(dbTable.Rows(i)("ccExpireYear"))
End With
End With
Next
Catch ex As MySqlException
MessageBox.Show("A DATABASE ERROR HAS OCCURED" & vbCrLf & vbCrLf & ex.Message & vbCrLf & _
vbCrLf + "Please report this to the IT/Systems Helpdesk at Ext 131.")
End Try
dbConn.Close()
End Sub
