setting text from a variable

[Jonathan_Arrien]

I have this code to set the text of a field from a variable:
FieldPtr        fld_ptrHc;

FormPtr frm=FrmGetActiveForm();
 
        if (ventana==1)
        {
 
 
 fld_ptrHc=FrmGetObjectPtr(frm,FrmGetObjectIndex(frm,EntradaHc1Field));
                FldSetTextPtr(fld_ptrHc,arrEntrada_Hc[0]);
                FldDrawField(fld_ptrHc);
        }

I can not retrieve the text of a variable int a field.I tried with 
FldSetUsable(field,true) before FldSetTextPtr but doesn't work.
Is something missing there???

 

        thank you.
