一个timer可以控制多个MSHFlexGrid单元格闪烁吗 急！

[yoyo9250]

我的程序中有一个MSHFlexGrid表格　我读取文件往里填数据　当符合一定的条件后　让对应单元格改变颜色使其闪烁，而这可能有很多单元格符合条件，用一个timer 能控制吗　怎么做　。我做的　最后就一个在闪呀
Private Sub Timer1_Timer()
Dim xx As Integer
Timer1.Enabled = True
Timer1.Interval = 500
counter = counter + 1
If counter > 2 Then
counter = 0
End If

Select Case counter
Case 1

For xx = 0 To record - 1
Grid1.Col = 2
Grid1.Row = lin(xx)
Grid1.CellBackColor = vbRed
Grid1.CellForeColor = vbWhite
Next
Case 2

For xx = 0 To record - 1
Grid1.Col = 2
Grid1.Row = lin(record)
Grid1.CellBackColor = vbWhite
Grid1.CellForeColor = vbRed
Next

End Select

End Sub
