chapter 10 p404

Hello,

In the code of the file "DisplaySource.asp" on line 30 I find the word "vbCrLf". I don't know what it is doing there. When I remove it, the file still seems to work fine, so I thought it was maybe an empty variable. I added "option explicit" and still I didn't get an error, so there goos my variable theory (I can't find any declaration of such a variable in the file).

Is there somebody who knows what this "vbCrLf" is doing there?

Here is the peace of code with the mysterious word in it:

Code:

  Dim objFileTextStream
  Set objFileTextStream = objFile.OpenAsTextStream(ForReading, TristateUseDefault)

  Dim strLine
  Do While objFileTextStream.AtEndOfStream <> True
    strLine = Server.HTMLEncode(objFileTextStream.ReadLine)
    strLine = Replace (strLine, Chr(9), "&nbsp;&nbsp;&nbsp;&nbsp;")
    Response.Write strLine
    Response.Write "<BR>" + vbCrLf
  Loop
  objFileTextStream.Close

vbCrLf is just a constant that represents the carriage-return/line-feed character pair which marks the end of a line in a text file. Its built in to VBScript so that's why you don't see it declared anywhere, its part of the language.
