[leesa]

I have a number field in a sequential file. Im going to read this file,
sum up this number and display the grand total in my application using
VB. Do anyone know how to do that??


Thanks in advance!

This is so basic programming.
Try to get a book about programming it does not matter how old it is.
Than get VBExpress

What you have to do is open a windowsform project
Drag from the toolbox a label on the form that is created
Click on that form
Search for MSDN.microsoft. com for "streamread er"
Follow one of the samples on that page

I hope this helps,

Dim fileReader As System.IO.Strea mReader
fileReader = My.Computer.Fil eSystem.OpenTex tFileReader ("C:\File.tx t")
Dim myData As String
Do
myData = fileReader.Read Line()
Loop While Not fileReader.EndO fStream

Homer,

If you write it so exact, would you not count in the routine.

Something as

> Dim myData As String[/color]
label1.text = ""[color=blue]
> Do
> myData = fileReader.Read Line()[/color]
Label1.text = CDbl(Label1.Tex t) + CDbl(myData.Sub string(0,6))
'to count the first 6 characters

Sure. I have a bunch of code in there for my purpose but the OP needs to add
his summing code.
