Q: I create a form field (Text Field) using Adobe LiveCycle Designer
7.0". In the program, I set that form field to a value in my variable
buf as:
itr.Current().GetValue().SetStr(buf);
, it creates an exception: "Object reference not set to an instance of
an object.".

A:
It is possible that the PDF form field doesn't have any value
associated with the field.
To go around this problem, use the following code when modifying the
form field:
// In C#
Field field = itr.Current();
field.SetValue(Obj.CreateString(buf));
// In C++
Field field = *itr;
field.SetValue(new Str(buf));
