Question

帮助！我试图用我的数据库中的项目用sql语句填充列表框，我不确定如何修复此错误，因为它不断出现。我的数据库只包含两个日期，但我需要它在将来可扩展，因此数据库存储日期。

Public ds As New DataSet 
Public con As New OleDb.OleDbConnection 'used to connect to the database
Public provider As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source ="
Public datafile As String = "Resources/database.accdb" 'database location and version
Public da As OleDb.OleDbDataAdapter
Public sqlstatement As String


ds.Clear()
    con.ConnectionString = connString
    con.Open()
    sqlstatement = "SELECT ShowDate FROM AvailableDates"
    da = New OleDb.OleDbDataAdapter(sqlstatement, con)
    da.Fill(ds, "Dates")

    lbxDates.DisplayMember = "ShowDate"
    lbxDates.DataSource = ds
    lbxDates.ValueMember = "ShowDate"
    con.Close()

出现错误'无法绑定到新显示成员'

lbxDates.ValueMember = "ShowDate"   line

Answer 1

您必须首先影响dataSource：

  lbxDates.DataSource = ds.tables("Dates")
  lbxDates.DisplayMember = "ShowDate"
    lbxDates.ValueMember = "ShowDate"

错误！ - 无法绑定到新的显示成员
