This example shows how to use eForm fields as placeholders for the insertion of text. In this example we simply replace each of the fields in a form with the name of that field.

First we create an ABCpdf Doc object and read in our template form.
using var doc = new Doc();
doc.Read("../mypics/form.pdf");
doc.Form.NeedAppearances = false; // for PDF 2.0
doc.Font = doc.AddFont("Helvetica-Bold");
doc.FontSize = 16;
doc.Rect.Pin = XRect.Corner.TopLeft;

We iterate through each of the fields. For each field we focus on the field. We then color the rectangle light gray and draw the name of the field in dark red.
var names = doc.Form.GetFieldNames();
foreach (string name in names) {
Field theField = doc.Form[name];
theField.Focus();
doc.Color.String = "240 240 255";
doc.FillRect();
doc.Rect.Height = 16;
doc.Color.String = "220 0 0";
doc.AddText(theField.Name);
doc.Delete(theField.ID);
}

Save

Finally we save.
doc.Save("eform.pdf");
