how to show a lots of data though MSFlexGrid [*resolved]

[junny]

I need to read a text file and output the data
I tried the code below
but because the data is so many that it takes much time to run
how to faster it?
please help me, thanks very much

'=======================================
TotalNum = 0 'the total row of the file, about 7050

'first loop to get the row of the file
Open App.Path & "\1.dat" For Input As #1
Do While Not EOF(1)
Line Input #1, MyData1
TotalNum = TotalNum + 1
Loop
Close #1

MSFlexGrid1.Rows = TotalNum + 1
'the second loop to send data to MSFlexGrid1
i = 0
Open App.Path & "\1.dat" For Input As #1
Do While Not EOF(1)
Line Input #1, MyData1
i = i + 1
TempString = MyData1
MyData1 = Split(TempString, ",")
With MSFlexGrid1
.Row = i
.Col = 0
.Text = MyData1(0)
.Col = 1
.Text = MyData1(1)
.Col = 2
.Text = MyData1(2)
.Col = 3
.Text = MyData1(3)
.Col = 4
.Text = MyData1(4)
End With
Loop
