Question

Here’s what I am doing:
I am logging messages and date time to a text file which I did successfully. Now I want to add the same to a Listview (or any other control which can be used to achieve this), also as and when the file is updated the Listview should be updated.

I am new to c# so excuse my lack of knowledge.

You can use FileSystemWatcher

Instantiate an FileSystemWatcher :

FileSystemWatcher watcher= new FileSystemWatcher();

watcher.Path = @"c:\folder_that_contains_log_file";

Set the notify filter : what events should be observed

watcher.NotifyFilter= NotifyFilters.LastWrite | NotifyFilters.FileName;

Specify that the FileWatcher can raise events :

watcher.EnableRaisingEvents = true;

Add event handler for the change event for all files from that folder :

watcher.Changed += new FileSystemEventHandler(Changed);

Capture the change event :

private void Changed(object sender, FileSystemEventArgs e)
{

// Get the ful path of the file that changed and rised this change event   

string fileThatChanged = e.FullPath.ToString();

//Check if file that changed is your log file

 if (fileThatChangedPath.equals("path_tot_the_log_file"))           
 {

   // clear items from ListView

   // Read from file line by line

   // Add each line to the ListView

 }

}
