1、

 
Dim lst As WinForm.ListBox = e.Form.Controls("ListBox1")
If lst.SelectedValue IsNot Nothing Then
    Dim tbx As WinForm.TextBox = e.Form.Controls("TextBox1")
    Dim Book As New XLS.Book(ProjectPath & "Attachments\" & lst.SelectedValue  )
    If  tbx.value IsNot Nothing Then
        Dim dlg As new SaveFileDialog
        dlg.Filter = "excel|*.xls"
        dlg.InitialDirectory = ProjectPath & "报表\"
        dlg.FileName = tbx.value & ".xls"
        If dlg.ShowDialog = DialogResult.OK Then
            Dim fl As String = dlg.FileName
            Dim Sheet As XLS.Sheet = Book.Sheets(0)
            Book.Build() '生成报表
            Book.Save(fl)
            Proc.File = fl
            Proc.Start()
        End If
    Else MessageBox.Show("请填写报表名称!","温馨提示:")
    End If
Else   MessageBox.Show("请选择报表模板!","温馨提示:")
End If

2、直接统计，不能统计关联表。具体问题做个实例说明。
