You VB .NET developers out there,
I have posted 3 threads requesting help on reading floating point values from a binary file but did not get any reply at all. Is it because I am asking a stupid question or noone really have a clue about the question I asked? I am pretty sure that many of you know the answer. For the love of GOD, please give me some pointers on this. Following code just throws an exception at the first FOR NEXT loop where reading starts (Pls see the code below). I did manage reading integers from a binary file but just can't get it work to read floating point values.

Let me try to explain what I am trying to do. My program should read floating point values (values range between -1.00 and +1.00) from a binary file. After reading those floating point values, it will do some basic math with the values and then will write them into file.
Here is the code:

Dim s1 As FileStream 'Load file 1
            Dim s3 As FileStream 'Save output

            If System.IO.File.Exists(TextBox19.Text) Then
                System.IO.File.Delete(TextBox19.Text)
            End If
            s1 = New FileStream(TextBox1.Text, FileMode.Open, FileAccess.Read)
            s3 = New FileStream(TextBox19.Text, FileMode.CreateNew, FileAccess.Write)

            Dim br1 As BinaryReader
            Dim bw As BinaryWriter

            br1 = New BinaryReader(s1)
            bw = New BinaryWriter(s3)

            Dim fLen1 As Integer
            Dim f1 As New System.IO.FileInfo(TextBox1.Text)


            fLen1 = f1.Length

            Dim snglRead1(fLen1) As Single
            Dim snglOutput(fLen1) As Single 'wıll hold results from division
             Dim i As Integer
            Dim j As Integer
            Dim k As Integer
            Dim m As Integer
            For i = 0 To fLen1 - 1
                 snglRead1(i) = br1.ReadSingle() 'EXCEPTION thrown right here
             Next

            For j = 0 To fLen1 - 1
                snglOutput(j) = snglRead1(j)
                bw.Write(snglOutput(j))
            Next


            s1.Close()
            s3.Close()
            MessageBox.Show("file created succesfully!", "Done")
            Me.Close()
        End If

So you've flooded the forum with threads asking the same question? That alone will cause people to ignore you.

>Following code just throws an exception
What exception? That's somewhat important information.

For i = 0 To fLen1 - 1
snglRead1(i) = br1.ReadSingle() 'EXCEPTION thrown right here
Next

maybe you trying to read while you reached the end of file ,

fLen1 = f1.Length

i think this return length on byte , try this

fLen1 = Int(f1.Length / 4)
Comments
good catch

Thank you Manal for your reply. As you suggested, I divided f1.Length by 4 and it worked. I appreciate it...
