Hi
I am trying to use Parallel.ForEach with ConcurrentBag and it work but to display a feedback I used progessbar control to display fname value , problem after few seconds I get error and the error message is not visible instead a wight box appear because of using a thread . any idea what is the problem in this code ?


int row_idx = 1;
ConcurrentBag<(int, string, float)> bag = new ConcurrentBag<(int, string, float)>();
Parallel.ForEach(elements, element =>
{

    string fname = element.name;
    float ftrack = (float)(element.track);


    var elementsToAdd = new (int, string, float)[]
    {
        (row_idx, fname, fsize)
    };

    bag.Add(elementsToAdd[0]);

    row_idx++;

    ProgressBar1.Text = fname; // <<---- error here
    ProgressBar1.Update();
    //Application.DoEvents();

});
