Hi Linda,

>I have a Windows form on which I need to display a series of text boxes, each displaying the value of a field from a different row of the dataset. In FoxPro, one way I have done is by using a macro to get an indirect reference to the text box name.

You can reference controls with something like this:
If you have a textbox named "txtSpecial1" you could find it with this and change it's text property.
int i = 1;
foreach (Control c in Controls)
{
     if (c is TextBox)
     {
          if (c.Name == "txtSpecial" + i.ToString()
          {
               c.Text = "MyText" + i.ToString();
          }
     }
}
I hope that helps to get you started.
