代码：

 Imports System.Data.SqlClient

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim conn = New SqlConnection("Data Source=.\SQLEXPRESS;AttachDbFilename=" & Chr(34) & "C:\Documents and Settings\user1\My Documents\Q692196DB.mdf" & Chr(34) & ";Integrated Security=True;Connect Timeout=30;User Instance=True")
        conn.Open()
        Dim cmd As New SqlCommand("select * from table1", conn)
        Dim da As New SqlDataAdapter(cmd)
        Dim ds As New DataSet()
        da.Fill(ds)
        DataGridView1.DataSource = ds.Tables(0)
    End Sub
End Class

注意，抓取那一列，设置为bit类型。

我有找到一些参考的资料，但似乎不能用

我将数据用 mydb.dbDataTable(我的元件) 载入dgv.DataSource
要如何在綁定后，再将变成checkbox

已经告诉你了，需要转换成bit
string sql = "select cast(0 as bit) as 抓, * from table1";
