What are the TextStream Object in ASP?

[Silent~Kid]

Hello friends,
I have just started with the Active Server Pages (ASP). I have recently got some work to complete in ASP. Since, I don't know much about the ASP, I am finding very difficult to complete that job. But thought that instead of giving up, I should take help of you guys.!! Actually I want to know what are the TextStream Object in ASP? Waiting for your replies.!! Please help me soon as possible.

The TextStream object is used to access the contents of text files. I have given you the example so that you can understand it more clearly. The following code creates a text file (D:\trial.txt) and then writes some text to the file. In the example, the variable f is an instance of the TextStream object. Here is an example :

<% 
dim fs, f 
set fs=Server.CreateObject("Scripting.FileSystemObject") 
set f=fs.CreateTextFile("D:\trial.txt",true) 
f.WriteLine("First Program!")
f.Close
set f=nothing
set fs=nothing
%>

You will have to know the properties and methods of the TextStream object. The following are the properties and methods of it :

• The property AtEndOfLine, returns true, if the file pointer is positioned immediately before the end-of-line marker in a TextStream file, and false if not.
• The property Column returns the column number of the current character position in an input stream.
• The property Line returns the current line number in a TextStream file.
• The method Close, closes an open TextStream file.
• The method Read, reads a specified number of characters from a TextStream file and returns the result.
• The method Write, writes a specified text to a TextStream file.
• The method Skip, skips a specified number of characters when reading a TextStream file.

I have given you the example below, in which I have created a new text file trial.txt and write some text to it. before using the CreateTextFile method to create a new text file, you will have to create an instance of the FilesystemObject object. The CreateTextFile returns a TextStream object that we will use to write some text to the file. Here is the coding for that example :

<%
Dim objFSO, objTStream
'Create an instance of the FileSystemObject object
Set objFSO = Server.CreateObject("Scripting.FileSystemObject")
'Create a text file named myFile.txt, replacing any existing one with the same name
Set objTStream = objFSO.CreateTextFile("C:\trial.txt", True)
'Write some text to the file
objTStream.WriteLine("Learn ASP Tutorials!")
objTStream.WriteBlankLines(1)
objTStream.WriteLine("The TextStream Object")
objTStream.WriteBlankLines(2)
objTStream.WriteLine("The TextStream object provides sequential access to the contents of text files.")
'Close the TextStream object
objTStream.Close
'Free up resources
Set objTStream = nothing
Set objFSO = nothing
%>

You can also create the TextStream Object using the OpenAsTextStream Method of file object. You can check the example for looking it :

<%
dim strpathinfo,strphysicalpath
strvirtualpath=request.servervariables("Path_details")
strphysicalpath=server.mapPath(strvirtualpath)

dim objFSO,objFile,objTextStream
set objFSO=createobject("scripting.filesystemobject")
set objFile=objFSO.getfile(strphysicalpath)
Set objTextStream = objFile.OpenAsTextStream(Forreading,TrisatteUseDefault)
%>
