I'd like to read a ascii file using VBA and the file has
(for example):
------------------------------------------------
Name Group Measured Modelled
d311 obsgroup 0.3270859 0.2853140
d312 obsgroup 0.3436139 0.3403970
--------------------------------------------------------
I have written:
dim dataname, groupname as string
Dim meas, modell as double

Line Input #1, textline ' Read text line
Do While Not EOF(1) ' Loop until end of file.
Input #1, dataname, groupname, meas, modell
Count = Count + 1
Loop
*******
But the variables does not read correctly. Could you help
me?

Iinput# is designed to read comma delimited data. You data is not comma
delimited.

You will need to use Line Input into a text string and parse it.

You could do this with the split statement if you are using xl2000 or later.

Hi Nazrul,

The Input # statement is looking for a data layout like this:

"d311", "obsgroup", 0.3270859, 0.2853140

where text strings are quoted and each value is separated by a comma. If
the data file is set up like that, you could use code similar to this to
read it in:

Private Type muData
Name As String
Group As String
Measured As Double
Modelled As Double
End Type

Sub GetData(rsFilePath As String)
Dim nFile As Integer
Dim sDummy As String
Dim uData() As muData
Dim sMeasured As String
Dim sModelled As String
Dim lRecord As Long

nFile = FreeFile
Open rsFilePath For Input Shared As #nFile

Line Input #nFile, sDummy
Do While Not EOF(nFile)
ReDim Preserve uData(lRecord)
With uData(lRecord)
Input #nFile, .Name, .Group, .Measured, .Modelled
End With
lRecord = lRecord + 1
Loop
Stop
Close #nFile
End Sub

You'd of course want to add error handling to trap for invalid file name or
format.

If your file is going to remain in the format you specified, you could read
each line in with Line Input # and parse the string with the Mid$()
function, assigning each part to the appropriate variable. Another
alternative is to use the FileSystemObject (part of the Scripting Runtime
library), which encapsulates a lot of this file I/O stuff and adds some nice
functionality. Search MSDN for "FileSystemObject" for more information on
that.
