End Select
CString = CString & Trim(Text1.Text) & "'"
rs.Open "select * from HUJI-3 where " & Trim(CString), conn, adOpenStatic, adLockReadOnly
If rs.RecordCount <> 0 Then
MSHFlexGrid1.Visible = True
Set MSHFlexGrid1.DataSource = rs
Text1.Text = ""
Text1.SetFocus

MSHFlexGrid1.Visible = False
MsgBox "没有此记录"
Text1.Text = ""
Text1.SetFocus
End If
End Sub

Private Sub Command2_Click()
Unload Me
Load hecaozuo3
