Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Button1.Text = setTabName("导体卡片")
    End Sub

    Public Function setTabName(ByVal AppName As String) As String
        Dim sqlcom As Foxtable.SQLCommand
        \' ByRef e As Foxtable.FormEventArgs
        \'Dim con As Foxtable.Connection
        Dim dt As Foxtable.DataTable
        Dim sqlstr As String
        sqlcom = New Foxtable.SQLCommand
        sqlcom.C
        sqlstr = "select * from 表格基础模板 where   应用程序 is not null"
        sqlcom.CommandText = sqlstr
        dt = sqlcom.ExecuteReader()
        For Each dr As Foxtable.DataRow In dt.DataRows
            setTabName = dr("选项卡描述")
        Next
    End Function
End Class

（1）为什么 sqlcom = New Foxtable.SQLCommand 通不过啊，一直“Foxtable.SQLCommand”的类型初始值设定项引发异常。

还有怎么指定 sqlcom.ConnectionName ？ 在foxtble 里指定一下外部数据源就可以用了。

 有没有这发面的资料啊。我想实现 有些功能抽象到VS2008 vbnet 里编写，在foxtable里引用vbnet写好的dll，进行编程。
