i think you should use invoke method.

here's my example.

delegate void myDelegate(string name);
//...
private void writeToTextbox(string fCounter)
{
    if (this.InvokeRequired)
    {
        myDelegate textWriter = new myDelegate(displayFNums);
        this.Invoke(textWriter, new object[] { fCounter });
    }
    else
    {
        textbox1.Text = "Processing file: " + fileCounter + "of" + 100;
    }
}
//...

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
    //...
    writeToTextbox(fileCounter.ToString());
}

in dowork i manipulate some textfile and i inform the user about how many files i have processed so far.
