Fix Length Data File 2

[AEtherson]

HI All

I am trying to ouput a fix length data file from VB.NET and I am having trouble do it. as it keeps on adding a byte at the beginning of the data with the length of the outputed string

Can you provide some of the code as it would make diagnosing the problem a whole lot easier?

Dim fs As New FileStream(Filename & ".idx", FileMode.CreateNew)
' Create the writer for data.
Dim sWriter As New BinaryWriter(fs)
Dim FileID As String

FileID = "175"
FileID = FileID.PadRight(10)

sWriter.Write(FileID)
sWriter.Flush()

Thanks

the output looks like this:

Byte(0) = &H3
Byte(1) = "1" : H31
Byte(2) = "7" : H37
Byte(3) = "5" : H35
...
Byte(9) = " " : H20

You are using a BinaryWriter and the Write does what it is documented to do.
"Writes a length-prefixed string to this stream in the current encoding of the BinaryWriter, and advances the current position of the stream in accordance with the encoding used and the specific characters being written to the stream."

Use a StreamWriter if you are wtring only Char or String.
