Updating ListView with Thread (+ extra thread questions)

[Skoder]

Hello, i am trying to keep updating a coloum for each ListViewItem in a ListView. I though i could just do this by a thread that kept updating every 10 secound but i can see that it is only possible to update / change / work with the ListView from the Thread that originally created it. Soo how can i achieve what i want ? Should the thread which updates the ListView instead maybe call a method like Invoke(TheMethod) every 10 seconds, or how should it be done ? Other Questions about Threads: I seem to get into 2 usuall problems. 1. I only want 1 thread to be able to be created and working on a method. I usually solve this by declaring the Thread thread globally within the class, soo before i create the Thread i check if thread == null ( create thread ), and in the code which the thread is running i then set thread == null when it exit. Is this okay ? or are there some smarter way to do it ? maybe some build in type / object or something ? 2. I only want 1 thread a time to run some code. Usually i solve this by declaring an Object threadLock globally within the class, soo i can just do lock(threadLock) { THE CODE HERE }. Any better way of doing that ? Best regards Martin :confused:

That's one way to do it. If all the thread does is refresh the listview, you could use the System.Windows.Forms.Timer[^] class instead.

You could use the IsAlive[^] property.

That looks fine. Regards Senthil _____________________________ My Blog | My Articles | My Flickr | WinMacro
