I have made a simple console application that creates a webpage from my
playlist, then uploads it to my webhost. I decided to convert it to a
windows service and use the FileSystemWatcher to monitor the playlist file,
this is where i became stuck. I know the service detects changes to the
playlist as when running the Change event of FileSystemWatcher, I add an
item to the event log. I've tried making the service without including the
upload line (this is an external call to pscp.exe) but the html file isn't
made so im thinking there is a problem elsewhere in the program. Here is the
code for the FileSystemWatcher changed event as I think this is where the
error is:
private void FileMonitor_Changed(object sender,
System.IO.FileSystemEventArgs e)
{
eventLog1.WriteEntry("It Should Upload it here :|");//This entry appears
in the event log
System.Threading.Thread.Sleep(5000); //I tried adding a 5 second pause
to ensure the playlist file is saved
StreamReader input = new StreamReader(@"c:\my music\playlist.pls");
StreamWriter output = new StreamWriter("playlist.html"); //This file is
never created
String inputString;
int numSongs = 0;
int totalLength=0;
inputString = input.ReadLine();
ArrayList songList = new ArrayList();
while((inputString != null)||!(inputString.StartsWith("Number")))
{
inputString = input.ReadLine();
if(inputString.StartsWith("Number"))
{
break;
}
numSongs++;
inputString = input.ReadLine();
int equalPos = inputString.IndexOf("=")+1;
String title = inputString.Substring(equalPos);
equalPos = inputString.IndexOf("=")+2;
int length = int.Parse(input.ReadLine().Substring(equalPos));
totalLength += length;
int lengthSec = length%60;
int lengthMin = (length-lengthSec)/60;
String zeroed = "";
if(lengthSec<10)
{
zeroed = "0";
}
String song = numSongs+". "+title+"
("+lengthMin+":"+zeroed+lengthSec+")";
songList.Add(song);
}
int avLen = totalLength/numSongs;
int avLenSec = avLen%60;
int avLenMin = (avLen-avLenSec)/60;
String avLength = avLenMin+":"+avLenSec;
String time = "";
if(totalLength>=3600)
{
int numSecs = totalLength%60;
int numMins = ((totalLength-numSecs)%3600)/60;
int numHours = ((totalLength-numSecs)-(numMins*60))/3600;

Any Help you can give would be appreciated.
