vb中DataGrid1怎么在界面中实现连接不同的数据库

Answer 1

Set DataGrid1.DataSource=rs1
通过按钮或其他条件切换数据源
Set DataGrid1.DataSource=rs2
rs1,rs2是数据集，需事先定义好。

Answer 2

If rs1.Bookmark = 1 Then rs.close
rs1.open......
if rs1.RecordCount > 0 Then
Set DataGrid1.DataSource=rs1
endif

If rs2.Bookmark = 1 Then rs.close
rs2.open......
if rs2.RecordCount > 0 Then
Set DataGrid1.DataSource=rs2
endif
