Hi,

Im trying to use the FolderBrowserDialog to select a folder in C#. At first I got a Thread exception, so I googled what was wrong and fixed that but now im stuck at a nother problem. I whant to know when a folder has been selected.

This is what i'v got right now.

 private void btnWorkingFolder_Click(object sender, EventArgs e)
    {


        var t = new Thread(SelectFolder);
        t.IsBackground = true;
        t.SetApartmentState(ApartmentState.STA);
        t.Start();

    }

    private void SelectFolder()
    {
        FolderBrowserDialog dialog = new FolderBrowserDialog();
        if (dialog.ShowDialog() == DialogResult.OK)
        {
            txtWorkFolder.Text = dialog.SelectedPath;
        }
    }
}

The problem here is that i cant Set the Text for txtWorkingFolder since im not in the same thread. I dont want to change the thread for txtWorkingFolder, so my question is this, how do I change it's value from the new thread once the DialogResult.OK has been set?

Thx for any help! /Marthin
