Get textbox value from a different thread

Question

I have tried using Invoke and a delegate, but it isn't returning the proper value...How do you have a delegate return a value when you use invoke?

Thanks.

Hi,

you can do this by declaring a return type for the delegete. Like this:

 delegate string GetText();

then create a method to retrieve textbox text

  string GetTextBoxText()
        {
            return textBox1.Text;
        }

then call the method using this code from a different thread:

string textBoxText = (string) textBox1.Invoke(new GetText(GetTextBoxText));
