问题:如何使用Datareport打印MSHFlexGrid中多条选中的记录MSHFlexGrid中的记录是通过查询得到的(连接有数据库),但是目标用户,要求对单击选中其中的几条记录进行打印,这个功能如何实现的??目前,自己可以实现单击选中某一天进行打印,或是打印MSHFlexGrid中的全部记录,但在打印“选中多条记录(连续或不连续都有可能)”上遇到了困难,特次求助了?多谢!!!

  1.   

    先生成一个RecordSet,和你报表的DataSource有相同结构,然后将选中的记录添加到生成的RecordSet中,最后 Set 报表.DataSource=RecordSet
      

  2.   

    MSFlexGrid1_MouseDown MSFlexGrid1_MouseUp事件中标记一下选中的行,打印的时候再根据这个标记来判断是否打印。以前我做了一个是用rowdata属性来弄的,翻出来了给你参考一下吧
    Private Sub MSFlexGrid1_MouseDown(Button As Integer, Shift As Integer, x As Single, y As Single)
        Dim i As Long, j As Long
        If MSFlexGrid1.MouseRow = 0 Then Exit Sub
        
        If Button = 1 Then
            If Shift = 2 Then
                With MSFlexGrid1
                    For j = 1 To .Cols - 1
                        .Col = j
                        If .CellBackColor = &H8000000D Then
                            .CellForeColor = &H80000008
                            .CellBackColor = &H80000005
