Toolbox items grayed out in VS 2010

Question

I have tried numerous attempts to fix this problem or bug, firstly by deleting the .tbd files from C:\Users\\AppData\Local\Microsoft\VisualStudio\x.0

I have also tried this:

Visual Studio "Tools" menu "Options" submenu "Windows Form Designer" tab "General" tab Set "AutoToolboxPopulate" to "True"

The ToolBox list is still not populating correctly and the "BackgroundWorker" component I need is grayed out. Any ideas?

Answer 1

I have found a solution to my problem, using the BackgroundWorker class in C# without using the component from the toolbox. In this case, I needed two seperate backgroundWorkers:

using System.Threading;

public partial class MainWindow : Window
    {
        private BackgroundWorker bw1 = new BackgroundWorker();
        private BackgroundWorker bw2 = new BackgroundWorker();

        public MainWindow()
        {
            InitializeComponent();

            bw1.WorkerReportsProgress = true;
            bw1.DoWork += new DoWorkEventHandler(bw1_DoWork);
            bw1.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bw1_RunWorkerCompleted);
            bw1.ProgressChanged += new ProgressChangedEventHandler(bw1_ProgressChanged);

            bw2.WorkerReportsProgress = true;
            bw2.DoWork += new DoWorkEventHandler(bw2_DoWork2);
            bw2.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bw2_RunWorkerCompleted);
            bw2.ProgressChanged += new ProgressChangedEventHandler(bw1_ProgressChanged);
        }


        private void bw1_DoWork(object sender, DoWorkEventArgs e)
        {
            StatsProcessor proc = new StatsProcessor();
            proc.CompareStats(listText1, listText2);    
        }

        private void bw2_DoWork2(object sender, DoWorkEventArgs e)
        {
            StatsParser parser = new StatsParser();
        }

        private void bw1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
        {
            progressBar2.IsIndeterminate = false;
            progressBar2.Value = 100;

            btnCompareStats.IsEnabled = true;

        }

        private void bw2_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
        {
            progressBar1.IsIndeterminate = false;
            progressBar1.Value = 100;

            btnFetchStats.IsEnabled = true;
        }

        private void bw1_ProgressChanged(object sender, ProgressChangedEventArgs e)
        {
            this.progressBar2.Value = e.ProgressPercentage;
        }

        private void bw2_ProgressChanged(object sender, ProgressChangedEventArgs e)
        {
            this.progressBar1.Value = e.ProgressPercentage;
        }

        private void btnCompare_Click(object sender, EventArgs e)
        {
            btnCompareStats.IsEnabled = false;

            StatsProcessor proc = new StatsProcessor();

            if (bw1.IsBusy != true)
                    {
                        progressBar2.IsIndeterminate = true;

                        // Start the asynchronous operation.
                        bw1.RunWorkerAsync();
                    }       

        }

        private void btnFetchStats_Click(object sender, RoutedEventArgs e)
        {
            btnFetchStats.IsEnabled = false;

            if (bw2.IsBusy != true)
                {
                       progressBar1.IsIndeterminate = true;

                       // Start the asynchronous operation.
                       bw2.RunWorkerAsync();
                }
        }
}
