If you want to write to a text file on the server you can use this code. This example shows how to use a text file that is a small counter. Just replace the name of the text file (textfile.txt) to the name you have on your text file.
Note that ON ERROR RESUME NEXT is used and it should be avoided in production code because it implies that errors are ignored.
<% on error resume next ' creates an instance of an server object set fso = createobject("scripting.filesystemobject") ' finds the text file set act = fso.opentext file(server.mappath ("textfile.txt")) ' reads the content from the text file, ' if the text file is missing it will be created further down counter = clng(act.readline) ' adds one counter = counter + 1 ' closes the server object act.close ' creates a new text file if it does not already exist a file Set act = fso.Createtext file(server.mappath("textfil.txt"), true) ' writing the new content to the text file act.WriteLine(counter) ' closes the server object act.Close ' prints the content of the text file to the screen Response.Write counter %>
