Getting Input from a Text File

by Allen Wyatt

True to its BASIC roots, VBA allows you to do file input on sequential files. This means you can open and read a sequential text file, loading the information from the file into string variables. The steps are simple. You only have to open the file, get the input, and then close the file. The following code is a common example of reading from a sequential file:

Dim Raw As String
Dim NumValues As Integer, J As Integer
Dim UserVals() As String

Open "MyFile.Dat" For Input As #1
Line Input #1, Raw
NumValues = Val(Raw)
ReDim UserVals(NumValues)

For J = 1 to NumValues
    Line Input #1, UserVals(J)
Next J
Close #1

In this example you should note that the first line read from the text file (MyFile.Dat) is assumed to contain a value that indicates how many items are to be read in from the file.

A quick note for those who have data files in which line 1 doesn't contain a value that indicates how many items are to be read in from the file:
Enclose the read and process code in a while ... wend loop like this
While Not EOF(1)
Line Input #1, Datensatz
' .... do stuff with the string variable Datensatz
Wend

I use this for reading gpx or html files.
