How can i use a BackgroundWorker with a timer tick?

Question

Decided to not use any timers. What i did is simpler.

Added a backgroundworker. Added a Shown event the Shown event fire after all the constructor have been loaded.

You can't just throw this code into a background worker and expect it to work. Anything that updates UI elements (labels, textboxes, ...) needs to be invoked on the main thread. You need to break out your logic to get the data and the logic to update the UI.

I would say your best bet is to do this:

In the timer Tick() method:

// Disable the timer.
// Start the background worker

In the background worker DoWork() method:

// Call your functions, taking out any code that 
// updates UI elements and storing this information 
// somewhere you can access it once the thread is done.

In the background worker Completed() method:

// Update the UI elements based on your results from the worker thread
// Re-enable the timer.
