'Mytable = CType(datagrid.DataSource, DataTable)
If mytable Is Nothing Then
MessageBox.Show("没有记录不能导出数据", "PurpleStar", MessageBoxButtons.OK, MessageBoxIcon.Information)

Dim MyFileName As String
Dim FileName As String
With SaveFileDialog1
.AddExtension = True '如果用户忘记添加扩展名,将自动家上
.DefaultExt = "xls" '默认扩展名
.Filter = "Excel文件(*.xls)|*.xls"
.Title = "文件保存到"
If .ShowDialog = DialogResult.OK Then
FileName = .FileName
End If
End With
