In C#, I have one timer (200 ms) and I have 50 label (or gauge C1) and I should check each value before assign to label or gauge.
Is it right way to use new thread for updating these label or gauge value??

U cánt have a thread ... to update the label ... try to use Background worker or something.  Once you create a new thread ... it doesn't have access to your winform control anymore.

I don't just develop software. I find solutions to your business needs.

Microsoft has a very good explanation and example for that: http://msdn.microsof...3(v=vs.95).aspx

What would be wrong with the System.Windows.Forms.Timer? Threaded or not, you'll have to Invoke the UI thread anyways... I don't even see the point in a BackgroundWorker here. The System.Windows.Forms.Timer should be enough for the job; it doesn't block the message queue in between intervals. 50 Labels at 200ms though? That is overkill...

You should only need a single (1) Textbox, and an interval of maybe 400 or 500ms. Past that, it gets to be even more useless, because nobody is going to be able to visually see (or maybe care?) about a super fast interval. Depending on what you're doing you may want to slow that down a bit.

What is this for? - What are you doing exactly?
