populating flexgrid with a file vb6

Answer 1

I'm not sure why rowcount is in your example code, but this works for me

namefile = App.Path & "\names.dat"
Open namefile For Input As #1
MSFlexGrid1.Rows = 1
MSFlexGrid1.Col = 1
While Not EOF(1)
    Input #1, x
    With MSFlexGrid1
       .Rows = .Rows + 1
       .Row = .Rows - 1
       .Text = x
    End With
Wend
End Sub

I've also pulled the .Col =1 out of your loop - you don't need to keep setting it and your loop will be faster than without it (not by much but repeatedly setting it is pointless)
