APPLIES TO

This article was previously published under Q248027
We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:
SUMMARY
This articles describes a process of returning a random background sound from a folder in your Web site using Microsoft Active Server Pages (ASP) and the Scripting.FileSystemObject.
MORE INFORMATION
Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements.
Random Sounds from ASP
Use the following steps to create an include file for use with ASP containing a function named RandomSound(). This function randomly returns the name of a sound based on the contents in a folder, which is passed by name to the function, or the name of a default sound if no sound files are found in the folder.
Create a folder named "Sounds" in your Web site's root folder.
Copy a few .wav, .mid, or .rmi sound files into the Sounds folder. (There are usually several in the %WINDIR%\Media folder.)
Save the following ASP page as "RandomTest.asp" in your Web site's root folder:<% @Language="VBScript" %> <% Option Explicit %> <html> <head> <!--#include virtual="/includes/RandomSound.inc"--> <bgsound src="<%=RandomSound("/sounds/","/sounds/default.mid")%>"> </head> <body> <h2 align="center">Random Background Sound Test</h2> <p>Hit "Refresh" in your browser to change sounds.</p> </body> </html>
Note: The call to the RandomSound() function passes the name of the default sound as /Sounds/Default.mid. You will need to change that to a valid sound file name and path when you want the function to a return default sound when a folder contains no sound files.
Create a folder named "Includes" in your Web site's root directory.
Save the following ASP code in the Includes folder as RandomSound.inc:<% Function RandomSound(strPath,strDefault) On Error Resume Next Randomize Timer ' declare all variables Dim objFSO, objFolder, objFiles, objFile Dim strFiles, strSound, strPhysical, strFile ' this constant has the names of valid file extensions ' it can be customized for more or less file types Const strValid = ".wav.mid.rmi" ' make sure we have a trailing slash in the path If Right(strPath,1) <> Chr(47) Then strPath = strPath & Chr(47) ' get the physical path of the folder strPhysical = Server.MapPath(strPath) ' get a File System Object Set objFSO = Server.CreateObject("Scripting.FileSystemObject") ' create a folder object Set objFolder = objFSO.GetFolder(strPhysical) ' get the files collection Set objFiles = objFolder.Files ' enumerate the files collection looking for valid files For Each objFile in objFiles strFile = LCase(objFile.Name) If Instr(strValid,Right(strFile,4)) Then ' add valid files to a string of file names strFiles = strFiles & strFile & vbTab End If Next ' split the names into an array strSound = Split(strFiles,vbTab) ' if we have an array... If UBound(strSound) > 1 Then ' get a random name RandomSound = strPath & strSound(Int(Rnd(1)*UBound(strSound))) Else ' otherwise return the default RandomSound = strDefault End If End Function %>
When you browse the RandomTest.asp page on a computer equipped with a sound card installed you should hear a random background sound file being played. As long as valid files are found in the Sounds folder the background sound should change each time you refresh the page.Copy a few .wav, .mid, or .rmi sound files into the Sounds folder. (There are usually several in the %WINDIR%\Media folder.)
Save the following ASP page as "RandomTest.asp" in your Web site's root folder:<% @Language="VBScript" %> <% Option Explicit %> <html> <head> <!--#include virtual="/includes/RandomSound.inc"--> <bgsound src="<%=RandomSound("/sounds/","/sounds/default.mid")%>"> </head> <body> <h2 align="center">Random Background Sound Test</h2> <p>Hit "Refresh" in your browser to change sounds.</p> </body> </html>
Note: The call to the RandomSound() function passes the name of the default sound as /Sounds/Default.mid. You will need to change that to a valid sound file name and path when you want the function to a return default sound when a folder contains no sound files.
Create a folder named "Includes" in your Web site's root directory.
Save the following ASP code in the Includes folder as RandomSound.inc:<% Function RandomSound(strPath,strDefault) On Error Resume Next Randomize Timer ' declare all variables Dim objFSO, objFolder, objFiles, objFile Dim strFiles, strSound, strPhysical, strFile ' this constant has the names of valid file extensions ' it can be customized for more or less file types Const strValid = ".wav.mid.rmi" ' make sure we have a trailing slash in the path If Right(strPath,1) <> Chr(47) Then strPath = strPath & Chr(47) ' get the physical path of the folder strPhysical = Server.MapPath(strPath) ' get a File System Object Set objFSO = Server.CreateObject("Scripting.FileSystemObject") ' create a folder object Set objFolder = objFSO.GetFolder(strPhysical) ' get the files collection Set objFiles = objFolder.Files ' enumerate the files collection looking for valid files For Each objFile in objFiles strFile = LCase(objFile.Name) If Instr(strValid,Right(strFile,4)) Then ' add valid files to a string of file names strFiles = strFiles & strFile & vbTab End If Next ' split the names into an array strSound = Split(strFiles,vbTab) ' if we have an array... If UBound(strSound) > 1 Then ' get a random name RandomSound = strPath & strSound(Int(Rnd(1)*UBound(strSound))) Else ' otherwise return the default RandomSound = strDefault End If End Function %>
When you browse the RandomTest.asp page on a computer equipped with a sound card installed you should hear a random background sound file being played. As long as valid files are found in the Sounds folder the background sound should change each time you refresh the page.Save the following ASP page as "RandomTest.asp" in your Web site's root folder:

Note: The call to the RandomSound() function passes the name of the default sound as /Sounds/Default.mid. You will need to change that to a valid sound file name and path when you want the function to a return default sound when a folder contains no sound files.

Save the following ASP code in the Includes folder as RandomSound.inc:<% Function RandomSound(strPath,strDefault) On Error Resume Next Randomize Timer ' declare all variables Dim objFSO, objFolder, objFiles, objFile Dim strFiles, strSound, strPhysical, strFile ' this constant has the names of valid file extensions ' it can be customized for more or less file types Const strValid = ".wav.mid.rmi" ' make sure we have a trailing slash in the path If Right(strPath,1) <> Chr(47) Then strPath = strPath & Chr(47) ' get the physical path of the folder strPhysical = Server.MapPath(strPath) ' get a File System Object Set objFSO = Server.CreateObject("Scripting.FileSystemObject") ' create a folder object Set objFolder = objFSO.GetFolder(strPhysical) ' get the files collection Set objFiles = objFolder.Files ' enumerate the files collection looking for valid files For Each objFile in objFiles strFile = LCase(objFile.Name) If Instr(strValid,Right(strFile,4)) Then ' add valid files to a string of file names strFiles = strFiles & strFile & vbTab End If Next ' split the names into an array strSound = Split(strFiles,vbTab) ' if we have an array...
